A Whale of an Exoneration

We found this interesting article about the early presence of the Basques in America (Canada specifically) at Montreal's based The Gazette:

Basques exonerated in decimation of Canadian whale population

Randy Boswell

In an impressive case of CSI-style sleuthing, researchers examining a single, 450-year-old whale bone from Labrador's south coast have exonerated the prime suspect in a whodunit from the dawn of Canadian history.

The DNA profile of a North Atlantic right whale's humerus — collected from the remains of a shipwreck at the historic Red Bay whaling site along the Strait of Belle Isle — shows that Canada's most endangered species was already suffering from a critically small population and a lack of genetic diversity before Basque whalers began harvesting the giant mammals in the 16th century.

The Basques have long been blamed for decimating the right whale population off Canada's coast. But the new research by a team of Canadian and U.S. biologists, published in the latest issue of the journal Conservation Genetics, indicates that right whales were rarely killed by the Spanish-based whalers and that oil-rich bowhead whales were almost exclusively their targeted species.

The first key finding in the centuries-old cold case was that only one right whale bone could be found among 218 specimens collected from historic East Coast whaling sites, meaning the bowhead was clearly the Basques' prime quarry.

Then, led by Trent University researcher Brenna McLeod, the team compared key genetic markers in the ancient right whale bone with those of present-day right whales — and found no significant differences.

The samples revealed a relatively low level of genetic diversity among the whale's North Atlantic population both today and in the past — a result that makes clear the species' problems in Atlantic Canada began long before the Basques arrived in the region in the early 1500s, the team has concluded.

The findings "are not consistent with the suggestion that Basque whaling activities were responsible for what was previously thought to be the largest reduction of the right whale population," the researchers state.

The results also indicate that "the major decline in this species occurred prior to whaling and that the pre-Basque population of right whales in the western North Atlantic was much smaller than has been assumed."

Today, scientists believe there are only about 350 North Atlantic right whales migrating annually between waters south of Nova Scotia — where they spend much of the summer and fall feeding and breeding — and Florida, where calves are typically born in late winter or spring.

The right whale can grow up to 18 metres in length, weigh more than 100 tonnes and live as long as 70 years.

Right whale advocates — including the new study's Canadian co-author, Moira Brown of Boston's New England Aquarium — have successfully lobbied for various fishing and shipping regulations aimed at protecting the highly endangered species.

But the latest findings, which the authors claim have "rewritten the history of the species," appear to point the finger at a post-1400 cooling period known as the Little Ice Age for the historically restricted numbers of North Atlantic right whales along Canada's eastern shores.

"Our research suggests that some of the factors (such as low levels of genetic variation) that may be limiting right whale recovery in the western North Atlantic have been present for far longer than we had thought," McLeod told Canwest News Service on Friday.

She added that the more scientists can learn about the right whale's history "the better we can understand how those factors are playing a role in the patterns and process of recovery in the species today."

The researchers note that while bowhead whales were the key Canadian target for Basque whalers, historic harvests of right whales throughout the broader North Atlantic world have decimated some populations.

In fact, the animal was named the "right" whale to target for easy hunting because it swims slowly and near the surface, typically stays close to the coast and conveniently floats to the top when harpooned.

In the decades following the New World discoveries of Christopher Columbus and John Cabot, the expert shipbuilders, sailors, fishermen and whalers from the Basque country bordering modern-day France and Spain had begun making transatlantic voyages to exploit coastal Canada's whale populations.

Lamp oil rendered from whales killed in the Strait of Belle Isle became the key commodity for the Basque entrepreneurs, who developed shoreline "factories" that produced thousands of barrels of oil and organized regular shipping schedules between Canada and Europe to deliver the product.

Although the presence of Basque whalers in 16th-century Canada was long known to historians, it wasn't until federal archivist Selma Barkham presented fresh evidence at an Ottawa archeological conference in 1977 that plans were made to search for physical traces of Basque activities in modern Labrador.

In 1978, a Parks Canada-led team of researchers discovered the sunken remains of a 1560s-era, three-masted whaling vessel.

Other major finds followed the discovery of the 20-metre San Juan, including three other "galleon"-class transport ships and a well-preserved "chalupa" rowboat used by whale-hunting crews in their deadly chase.

Land-based excavations yielded burial sites, clothing and countless other relics, including hundreds of whale bones.


There just a couple of things we would like to point out; the Basques were fishing off the coast of what one day would be known as Canada long before Columbus and Cabot stumbled upon America. And there is no reason to call them Spaniards, in the early 1500 (the estimated date given to us by the author) the Basque kingdom of Navarre was still an independent and sovereign political entity. The Spaniards began the final assault until 1512 and the Basques were still fighting all the way to 1524. Castile and Aragon managed to get control of the Basque homeland to the south of the Pyrenees, to the north, Donibane Garazi became the kingdom's capital city for many more decades.

The interesting part is, how come the Native Americans living close to the Basque fisheries did not suffer any European disease epidemics like their neighbors to the south?

Integrating Through Own Identity

Here you have a note published at Basqueresearch:

Basqueness is an element of social integration for the Basque communities in the United States

A PhD thesis undertaken at the University of the Basque Country (UPV/EHU) involved the ethnographic study of young dancers belonging to the Zazpiak Bat Basque Club based at Reno (Nevada, USA). Using this case, how the dances and activities of the Basque communities intervene in the process of multicultural socialization in the United States, was studied.

The PhD thesis aimed to show the subjectivity of persons making up the Basque community in the United States, to which end a study was undertaken of how the dances and activities of these Basque communities in that country intervene in the process of multicultural socialization in that North American country.

The author of the thesis is Ms Clara Urdangarin Liebaert and has entitled her work Dancing the Jauzi under the stars and stripes: an ethnographic study of the Zazpiak Bat Group of Dancers from Reno, Nevada. In order to carry out this research she stayed at Reno from February 2003 to January 2004.

Through the rehearsals and performances and so on of the Basque folk dantzaris from Reno, the researcher was able to see how a code of communication adjusted to the social context in the United States was internalized. Thus, Basqueness is an element of social integration in this multicultural society.

Internal and external logic

The author analyzed the relationship between the internal logic of the Basque dances and the external logic of the dancer. Each one of these logics is divided into four sections, each as a function of the relation of the subject to space, to time, to the other actors and to objects.

The socialization of United States Basques as demonstrated in this work is within a social context characterized by a multiracial society which strives to marry the different origins of its inhabitants with the social cohesion of the country. To a certain extent, the features distinguishing Basques from other ethnic groups in the United States have the features of multiculturality: a United States citizen linked to an immigrant origin, identified with customs and a desire for brotherhood with other groups.

The results show the characteristics of the internal logic of Basque dancing and the social framework in which it happens. The Basque dance in the United States presents a citizen who associates with other Basque citizens to form a group and thus build their identity within the framework of North American minorities. In this way, the Basque fiestas construct a Basque who presents himself or herself to the multicultural community with pride. The Basques dance in order to exist in the multiethnic mosaic that is the United States.

Material culture

Material culture —culture associated with objects— shows a United States person who uses objects of consumption linked to his or her own identity. In the same way, Basque activities underpin their identity —peaked caps embroidered with brotherhood motifs, balloons and banners in white, red and green and car license plates with the inscription proud to be Basque—.

Also, the liking for uniforms is quite clear with the clothing of the dantzaris and other who actively participate in the fiesta. According to the researcher, these objects link the citizen to the group they belong to and, in this case, the Basque with his or her ethnic community.

Information about the author

Ms Clara Urdangarin Liebaert (London, 1960) is qualified as a psychiatric nurse and a graduate in Physical and Sports Education. She undertook her PhD thesis under the direction of Mr Joseba Etxebeste Otegi from the Department of Physical Education at the Faculty of Physical Sports Activities Sciences (UPV/EHU), and spent time at the Center of Basque Studies at the University of Reno (Nevada). She is currently working as a lecturer in the Department where she carried out her PhD.

Archaeological Findings at Lizarate Pass

This note was published at EiTB:

Remains of a medieval castle at the gates between Gipuzkoa and Alava

Olwen Mears

The historical significance of the ancient doorway between two Basque provinces comes further to light with the discovery an ancient dwelling and inn.

Those responsible for leading excavations into the St Adrian tunnel (between Gipuzkoa and Alava) which started a year ago have been amazed by recent findings.

"This is double what we expected (to find)," said one archaeologist. "Without doubt, what is emerging here is a big surprise."

Remains which have been found inside the tunnel, where today only the old Roman road and an ancient chapel still stand, have lead archaeologists to conclude that there once stool a medieval castle of some magnitude, as well as possibly an inn and a cemetery. All of these are evidence of the importance of the underpass which joins the Basque provinces of Gipuzkoa and Alava.

The Lizarate pass, better known as the San Adrian tunnel, was once the entrance to Gipuzkoa and the Roman road that runs through it united the ancient kingdom of Castille with France.

"It was like the N1 (important highway that runs from Madrid to the Basque town of Irun) of its day ... marketers, princesses,.. everybody traveling between Castille and France would have to have passed through here," explained one of the diggers.

Furthermore, remains have also been found from the Bronze Age, two metres below where the current archway stands, proving that the passageway was previously much wider.

Representatives from the council of Gipuzkoa will continue to encourage the archaeological exploration of the site with the objective of retrieving this historically strategic spot of the Aizkorri Aratz national park.

As one council deputy explained: "Firstly what we want to do is preserve the site and then of course give it the importance that is warrants."


This archaeologist needs some history classes, after the Romans there was no Castille and for hundreds of years there was a Basque kingdom called Navarre between Spain and France. Gipuzkoa and Araba where both provinces of that Basque sovereign state we call Nabarra.

Our Irish Cousins

This article was published today at Irish Times:

Genetic studies show our closest relatives are found in Galicia and the Basque region

DICK AHLSTROM

ANCESTRAL LINKS: WHAT DO pygmy shrews, badgers, mountain hares, pine martins and Irish people have in common? All probably originally came to Ireland on boats from northern Spain.

Our closest relatives are found in various parts of Galicia and the Basque country according to genetic studies led by Prof Dan Bradley of Trinity College Dublin’s Smurfit Institute of Genetics. He presented his research over the weekend at the American Association for the Advancement of Science annual meeting in Chicago.

He was joined by Queen’s University Belfast archaeologist and linguist Prof James Mallory who talked about efforts to link these DNA studies with the transmission of languages across western Europe.

The chair of the session was the Government’s chief scientific adviser, Prof Patrick Cunningham.

Prof Bradley and colleagues have done extensive genetic analysis into where the Irish came from and how they got to Ireland. He studies genes associated with the Y chromosome, a genetic inheritance that comes via the father.

By tracking the presence of certain Y chromosome markers he can travel back in time to map our relatedness to others across Europe. He explained how he had also done this with the two main species of cattle, the familiar flat-backed cattle and the hump-backed cattle seen in India and Africa.

The human data definitively showed that our strongest relatedness was with the northern Iberian peninsula, with this genetic signal strongest for the Irish living today in the west of Ireland. These in turn were likely the closest relatives of the migrants who originally settled in Ireland.

Genetic studies of Irish fauna also showed this distinctive signal, he said. “The Irish badgers are Spanish, but the British badgers are not. The fauna of Ireland seems to be divergent. How does one explain this,” he asked.

The most likely explanation was that the island was settled by migrants from northern Spain as the glaciers that covered Ireland from the last ice age melted away. “It seems to me that most animals in Ireland came by boat. There seems to have been some communication with southern Europe.”

The Book of Invasions from the 8th century talked about an invasion by the Spanish king Milesius, he said.

His group also looked for genetic linkages between people sharing a common surname, something passed along from the male lineage like the Y chromosome.

They found linkages that traced back, to the famous Ui Neill kindred, from whom Niall Noigiallagh, Niall of the nine hostages was descended.

Prof Mallory described attempts to match up the transmission of languages with the dispersal of DNA as people migrated across Europe. It was extremely difficult however due to confounding influences including language transmission via “elite dominance”.

Settled areas with a unique language later taken over by invaders would see language displacement, with the newcomers imposing their own language. However, the local gene pool would remain and would dilute the genetic influence of the newcomers.

This was possibly the reason why when one looked for genetic evidence of the Celts in Ireland these Celtic genes could not be found. Studies of this dynamic has occurred in what is now Hungary showed a mismatch between the dominant language and the dominant genetic influence. “Modern DNA is no predictor of the modern Hungarian language,” Prof Mallory said.


Maybe that's why the Irish are so adamant at defending their identity from their meddling and often violently invasive neighbors, they got that from their Basque ancestors.

Studying the Urumea River

The article you are about to read was published at Environmental Expert:

A flood study of the Urumea River in The Basque Country

Source: DHI Water & Environment

The Urumea river catchment area which is located in the Basque Country in the northern part of Spain has historically been seriously affected by flooding. The districts most affected by the frequent inundations are the municipalities of San Sebastian, Astigarraga and Hernani. As recently as October 2008 a minor flood was experienced in Hernani. In 2006 and 2004 major flood events with significant damage occurred.

To improve this situation, the Department of Environmental Affairs of the Basque government will in the coming years invest 60 million € in construction of 18 preventive measures. The overall objective of the project is to 'Let the river breathe' and consequently reduce the frequency of flooding of the Urumea River.

The preventive measures include substitution of a number of exciting bridges, which at the moment are obstructing the river flow, establishment of by-pass channels, enhancements of the riverbed in defined sections, and creation of public recreational areas. All actions amid at increasing the flow capacity of the river, while respecting the environment and natural flow path of the river.

In order to investigate in detail these 18 predefined interventions, DHI was contracted to set up a 2D model (MIKE FLOOD) of the 15 km stretch from Hernani in the south to San Sebastian in the north.

In the First phase of the study a model of the actual situation was established, incorporating all relevant bridges and hydraulic structures. The model was calibrated against observed data from the flood event that occurred in the winter of 2004 and it was verified against the smaller flood event in 2006.

Following the calibration/verification the model was executed for the three return periods T=10, 100, and 500 years.

In the second phase the 18 corrective measures was incorporated into the model, and simulations of the T=10, 100, and 500 years return periods was carried out.

The projects design return period was set to T=500 year, which means that the planed flood protection measures should be capable of withstanding a flood that statistically should happen once every 500 years. (Which could be tomorrow!)

The result of the 500 year event simulation is shown below: The green color shows the extent of the flood in the actual situation, while the blue color represents the future situation with the improvement in place.

Comparison of the simulation results of the actual situation and the future situation when all the improvements are in place.

It is obvious that the flood prevention measures will have the desired effect; - the simulated 500 year flooding will not extend beyond the defined floodplain (yellow line).

The third phase of the study consisted in visualization the results as video animation, which was used for the Basque government press releases and information material. The videos were generated partly by incorporating the results in Google Earth using the DHI GE plug-in and partly by using the Result viewer.

Notes regarding the model configuration.
The bathymetry/topography of the floodplains was defined using available LIDAR data (1x1m), while the description of the riverbed was based on HEC-RAS cross section data. The HEC RAS data was first converted into a MIKE11 model, which then was used to create a bathymetry specifically for the riverbed. This riverbed bathymetry was then “burnt” into the floodplain bathymetry, and thereby generating a bathymetry that integrates the LIDAR data with the detailed data from the HEC RAS model.

Fifteen bridges were incorporated into the model. The description of the flow through (and over) the bridges was accomplished either by directly incorporating the bridge pillars into the bathymetry or by modeling the bridges in MIKE11 and then linking then dynamically to the 2D model via MIKEFLOOD. The decision on which one of the two methods to apply was taken based on the physical dimensions and the design of each bridge.

The model was calibrated against observed data from the flood event that occurred in the winter of 2004 and it was verified against the smaller flood event in 2006.

The model displayed an excellent correspondence with the observed data, except in the lower part of the river. This inconsistency was suspected to derivate from erosion of riverbed that will occur in the real life situation. Meaning that, the concrete erosion of the riverbed material will increase the rivers flow capacity and thereby function as natural flood prevention measure.

The phenomenon was investigated a bit further by use of a simple relation between the calculated maximum water velocity and the erosion depth. The figure below shows a specific river cross-section without erosion (the brown line) and with erosion (grey line). The red line represents the flow velocity.

The river cross sections with sedimentation and without sedimentation.

The results of the two simulations for the 2004 event are shown below, - without erosion to the left and with erosion to the right-. As it can be observed, the situation without considering erosion exhibits a much larger inundation than the situation where the erosion is taken into consideration.

If we compare the simulated flood maps with the actual flood event of 2004, the simulation with erosion (right) correspond almost perfectly to what was observed during the flood, while the simulation without, overestimates the floods.

Results of the simulations of the 2004 event: Left: without erosion, right: with erosion.

The conclusion of the analysis was that the suspicion is largely supported by the modeling results, but considering the very simple erosion description applied, the phenomenon should be investigated more thoroughly using real sediment data and a more sophisticated model 3 dimensional model (MIKE 3 FM).

Research on Conservation of Historic Sites

The correct conservation of sites with a historic value is of great importance, this is why I wanted to reproduce this article published at Basque Research:

Sánchez Beitia: ‹‹One has to know and understand heritage sites before embarking on any intervention››

Santiago Sánchez Beitia is a doctor in Physics and teaches first and second years and the PhD course in the School of Architecture at the University of the Basque Country (UPV/EHU). The research team he leads is pioneer in the analysis of the state of conservation of heritage sites, having adapted techniques from other spheres of study to this end.

Dr Sánchez Beitia has been working on the analysis of the state of conservation of archaeological elements at heritage sites since 1991. “One has to know and understand the monument from a structural perspective before embarking on any intervention. The construction has to be inspected, examined and listened to – but techniques are needed for this”, he explained. The analysis of the state of conservation aims to deduce what the loads supporting the construction are, the structural changes that have taken place over time and, moreover, non-structural problems — dampness, degradation of materials, movements of earth, etc. “We analyse buildings, walls, historical sites, etc.” he explained. To this end, they have adapted techniques and ways of analysing developed from very different fields than that under study.

The Hole-Drilling method

The team led by Mr Sánchez Beitia stands out for having adapted the Hole Drilling method — used for measuring stresses and deformations — to the study of architectural heritage sites. “This method enables us to find out the exact load bearing on a support structure, such as pillars, buttresses, retaining walls, etc., while affecting its physical integrity in the least possible way, as it dramatically improves performance compared to previous, more destructive, techniques”, explained the research worker.

The Hole Drilling method involves making a small orifice — just 36 millimetres in diameter and 36 millimetres deep — in the stone, using a drill onto which a series of feelers is fixed. “These feelers record the displacements – in the order of micros — that take place around the orifice. The analysis of the data obtained enables us to calculate the stresses on or the forces supporting the pillar”, explained Dr Sánchez Beitia. The application of this method is recognised worldwide and Mr Sánchez Beitia’s team has published a number of articles on the topic, in collaboration with other universities.

From Berlin to Cairo

Amongst elements studied by Mr Santiago Sánchez Beitia and his team are the Mayor de Comillas Seminary, the pillars of Santa María del Mar, the Church of Santa Maria del Pi and the Gothic Cathedral of Barcelona — the three gothic representations in the Catalan city; the Cathedral of Tarazona, the Casa Botines or the flying buttresses of the Cathedral in Palma de Mallorca. Outside the Spanish state, the Church of Saint Jacobs in Louvaine, the basement floor of the Altes Museum in Berlin or the Sultán al-Ghawri aqueduct in Cairo. “We publish studies with universities from other countries, which brings an internationalisation to what is being investigated at the School of Architecture at the Donostia-San Sebastian campus of the UPV/EHU”, explained the researcher.

Although a lot of work is undertaken outside the Autonomous Community of the Basque Country, they also carry out analyses here. “We were the first to use this technique in the Cathedral of Santa María in the Basque capital city of Vitoria-Gasteiz, together with Giorgio Croci”, he stated. Moreover, they have examined the walls of Hondarribia in the neighbouring province of Gipuzkoa, and will shortly start on the analysis of their state of conservation, and on the consolidation of and intervention in the monastic site at Sasiola in Deba, in the same province.

Conservation of Sasiola

“The current state of Sasiola would make you cry”, complained Dr Sánchez Beitia. “Two of the vaults have caved in and the third is full of cracks”. Luckily, the situation of this heritage site is improving thanks to the fact that the Gipuzkoa provincial Government is going to carry out an intervention. “Our team is taking part in this project as a body associated to the architectural study which received the adjudication”, explained the researcher. With this project an exhaustive analysis of the state of conservation was made in order to be able to to project the future intervention at Sasiola in the most suitable manner.

Sasiola was a strategic point in Gipuzkoa until the XVIII century, its Franciscan monastery being a landmark on the coastal Camino de Santiago route and a contemporary of the better-known one in Aranzazu. It used to be an important trading centre, being a meeting of the commercial ways between Castille and the coast and the trading routes to the West Indies. With time and, above all, after the disentailment of the Church lands at Mendizábal, it fell into disuse. “There is a serious structural problem there and it could cave in at any moment”, suggested Mr Sánchez Beitia. “I go there a lot and every year I take a group of PhD students so they can get to know it”.

Scientific treatment of the analysis

Santiago Sánchez Beitia underlines the lack of awareness about these intervention processes “having to be based on a scientific treatment integrated into international scientific currents. For some time now Italy and Belgium, for example, have had a scientific treatment protocol for conservation analysis, but here, until recently, we have been on the margins”, pointed out the Mr Sánchez Beitia. He explained that in Catalonia they accept the need of this type of analysis that tries to understand the monumental site in order to subsequently draw up a project, carry it out and undertake conservation. “In Italy a scientific treatment protocol for conservation analysis is a legal obligation. Here it is at the whim of the concern or otherwise of officialdom”, he pointed out.

Thanks to this type of analysis, to the new techniques, to the research, there are less and less buildings that cannot be intervened and recovered. “The Cathedral of Tarazona has been closed for years because it was thought irrecoverable and it now has a Intervention Plan Director. There is always a solution and we are evermore imaginative”, he concluded.

Light and Dark

This article comes to us thanks to Basqueresearch:

Throwing light on the dark side of the Universe

Although we may believe humans know a lot about the Universe, there are still a lot of phenomena to be explained. A team of cosmologists from the University of the Basque Country are searching for the model that best explains the evolution of the Universe.

We usually have an image of scientists who study the Universe doing so peering through a telescope. And, effectively, this is what astrophysicists de: gather data about the observable phenomena of the Universe. However, in order to interpret this data, i.e. to explain the majority of the phenomena occurring in the Universe, complicated calculations with a computer are required and which have to be based on appropriate mathematical models. This is what the Gravitation and Cosmology research team at the University of the Basque Country (UPV/EHU) is involved in: analysing models capable of explaining the evolution of the Universe.

Supernovas, witnesses to acceleration

One of the phenomena that standard models of physics have not yet been able to explain is that of the accelerated expansion of the Universe. Although Einstein proposed a static model to describe the Cosmos, today it is well known, thanks to supernovas amongst other things, that it is, in fact, expanding. Supernovas are very brilliant stellar explosions that, precisely due to this, provide useful data for exploring very distant regions of the Universe. By measuring the quantity of light that gets to us from a supernova, we can calculate its distance from us, and its colour indicates the speed at which it is distancing itself from us – the more reddish it is, the faster it is travelling. In other words, comparing two supernovas, the one that is distancing itself more slowly from us is a more bluish colour. According to observations by astrophysiscists, besides supernovas distancing themselves from us, they are doing so more and more rapidly, i.e. distancing themselves at an accelerated velocity, just like the rest of the material of the Universe.

Looking for dark energy

The energy known to exist in the Universe, however, is not sufficient to cause such acceleration. Thus, the theory most widely accepted within the scientific community is that there exists a ‘dark energy’, i.e. an energy that we cannot detect except by the gravitational force that it produces. In fact, it is believed that 73% of the energy of the Universe is dark. The dark energy debate is not just any theory: its existence has not been proved but, without it, standard models of physics would not be able to explain many of the phenomena occurring in the Universe.

So, what is dark energy exactly? What are its characteristics and have these properties always been the same or have they changed over time? These are questions, amongst others, that researchers at the Faculty of Science and Technology at the UPV/EHU, under the direction of Dr. Alexander Feinstein, are seeking to answer.

The unique characteristic of dark energy known to us is that it possesses repulsive gravitational force. That is, unlike the gravity we know on Earth, this force tends to distance stars, galaxies and the rest of the structures of the Universe from each other. This would explain why the expansion of the Universe is not constant, but accelerated. Nevertheless, this phenomenon can only be detected when achieving observationally enormous, almost unimaginable distances. This is why it is so difficult to understand the nature of dark energy.

The theory of phantom energy

To what point can the Universe expand? If this repulsive force is ever more intense, might it be infinite? This is one of the problems that the UPV/EHU researchers are focusing on. Such powerful dark energy is known as phantom energy, with which the Universe is able to expand to such an extent that the structures we know today would disappear.

This research group considers that the phantom energy model may be the most suitable to explain the accelerated expansion of the Universe. Amongst other things, the team has come to this conclusion after analysing the distribution of galaxies and the background microwave radiation which has inundated all of the Cosmos since shortly after the Big Bang. These waves travel in every direction and enable the exploration of what occurred at tremendously remote instants in time, moments close to the start of it all.

Wave Energy in Euskal Herria

Here you have another article from Basqueresearch:

Iberdrola and Tecnalia install first prototype for producing wave-sourced energy

Iberdrola and Tecnalia Technological Corporation have installed, within the framework of the Oceantec Project, the first prototype for producing energy using the movement of waves along the coast of the Basque province of Gipuzkoa - specifically Pasaia. The initiative has a budget of 4.5 million euros and aims to launch a high performance, low-cost-wave energy capture device.

This first prototype, built on a scale of 1:4, will be ready for trials within months in order to test its performance and ensure that it does not represent a risk for the surrounding area. If the technical verifications are favourable, Iberdrola and Tecnalia anticipate developing a new, full-size device and connected to the electric grid.

This second installation in which both companies are working has a power output of 500 kilowatts (kW) and can produce enough renewable energy in one year to supply the domestic consumption of 950 homes.

The Oceantec Project will enable generation of business based on developing a renewable energy source, the creation of opportunities for industrial growth and rationalisation in the Basque Country and support for making the most of energy resources along the coast of Gipuzkoa and Bizkaia, in the Basque Country Autonomous Community.

Along these lines, it can be pointed out that a number of Basque firms have taken part in the manufacture of various systems contributing to this prototype, such as Vicinay Cadenas and Metalúrgica Marina.

Iberdrola and Tecnalia Technological Corporation have undertaken this initiative through Perseo, the promotion body for R+D+i investment in electricity launched this year. With an annual budget of 6 million euros, its main aim is the support of high value technological projects in the field of renewable energy and the environment.

Lineages in the Cantabrian Coast

This article comes to us via the Basqueresearch page:

Study confirms importance of lineages in the Cantabrian coast of the Bay of Biscay in the European genetic map

A PhD thesis at the University of the Basque Country (UPV/EHU) involved a detailed study of the maternal lines (mitochondrial DNA) of three autochthonous human populations in the Cantabrian coast area of the Bay of Biscay and which aimed to clarify the role of these populations in the postglacial recolonisation in Europe. The study, carried out by Dr. Sergio Cardoso Martín, confirmed the importance of the proposed H1 and V lines as well as considering lines J1c, U5b and T2b as significantly important demographic landmarks in the history of the evolution of European human populations.

One of the aspects that has sparked most interest in recent years in the field of Population Genetics is the postglacial repopulation of Europe that happened about 15,000 years ago. A great amount of this research has focused on the analysis of mitochondrial DNA or maternal lines, using them as a tool to assess the impact of large human migrations in the make-up of the genetic heritage of current European populations.

With his thesis entitled, “Diversity of the mitochondrial genome in autochthonous populations in the Cantabrian coast area: Traces of postglacial recolonisation in Europe”, Dr. Sergio Cardoso Martín explored the involvement of the Franco-Cantabrian populations of the Franco-Cantabrian refuge during the postglacial recolonisation of Europe, by analysing the variability of mitochondrial DNA. The Franco-Cantabrian refuge, extending from the south-east of France to the eastern end of the Cantabrian coast, is considered to have been the main settlement for groups of humans who arrived from the north of Europe during the last glacier age, in order to escape from the extremely adverse weather conditions.

Sergio Cardoso Martín has a degree in biochemistry and is currently working in postdoctoral research. His PhD thesis was directed by Dr.Marian Martínez De Pancorbo of the Department of Zoology and Animal Cell Biology at the Faculty of Pharmacy (UPV/EHU) and of the General Genomic Research Service: DNA Bank, and by Dr. Miguel Ángel Alfonso Sánchez, of the General Genomic Research Service: DNA Bank.

Looking for genetic markers

In order to carry out this research, an analysis was undertaken of a sample made up of 194 individuals belonging to three autochthonous populations from the Cantabrian coast: from the Arratia and Goierri valleys in the Basque Country, the Valley of Baztan in Navarre and from the Pas valley in Cantabria. The HVI and HVII segments from the mitochondrial DNA control region of the 194 participating individuals were sequenced. Moreover, the complete mitochondrial DNA for 43 of the individuals was sequenced with a twin objective: to reconstruct the development of the various maternal lines from the Franco-Cantabrian refuge area and to confirm the results of the analysis of the sequenced segments. The results of this analysis enabled the classification of the individuals under study into genetic families known as haplogroups. The frequency of the various haplogroups was also analysed - their spatial distribution throughout Europe and the age of the most recent common ancestor to the various lines was estimated.

Reduced genetic diversity

Most of the 194 individuals analysed presented mitochondrial haplogroups characteristic of the European populations. Additionally, very infrequent haplogroups were found and exceptionally individuals, carriers of a haplogroup of African origin, were found in the Pas Valley.

The most frequent haplogroup amongst our samples from the Basque Country and Navarre turned out to be H, and, more concretely, the subhaplogroup H1. Also notable amongst these two populations was the high frequency of the J1c line, and particularly in the case of the north of Navarre, lines U5b and T2b also registered notable frequencies. In the Pas Valley, on the other hand, the greatest frequency corresponded to haplogroup V. The adverse climate and the orography of the terrain would have favoured a marked isolation of the populations and, in consequence, a local genetic microdifferentiation that is reflected today in the predominance of some or other maternal lines in each of the analysed populations.

Apart from presenting caracteristic haplogroups, as regards diversity, the research showed that the three autochthonous populations studied were characterised by reduced values for genetic diversity with respect to other European populations, even with respect to the rest of the Iberian Peninsula. The populations of the Basque Country and the Pas Valley, together with that of Galicia, demonstrate the lowest diversity of lines within the European context. The population of the north of Navarre showed values within the range of European populations taken as reference. The author of this study has put forward these differences in mitochondrial genome diversity as being related to the lower isolation of northern Navarre, given the powerful influences of the presence of Romans, Arabs and Jews in the region, as well as its location on the pilgrim route to Santiago de Compostela.

The comparison undertaken with other European populations showed that certain mitochondrial haplogroups presented their maximum level of frequency in the area of the Franco-Cantábrico refuge. It can be deduced from these findings that the definitory mutations of these haplogrupos could have originated in the refuge zone, or otherwise could have been transported by humans who retreated from the north of Europe, thus substantially increasing their frequency subsequently as a consequence of the genetic drift, a phenomenon known as the “founder effect”.

Genetic markers of recolonisation in Europe

The study enabled the confirmation of the importance of lines H1 and V – the most abundant amongst the sample of analysed individuals – as genetic markers of the postglacial recolonisation from the refuges of southeast Europe. Also, the study’s findings showed that the T2b, J1c and U5b haplogroups constitute “paleolithic maternal lines”, well conserved to date and with relevant frequencies in the Franco-Cantabrian refuge area. This is why it is recommendable to include the area in future studies aimed at finding genetic tracks of the postglacial repopulation of Europe and at the evaluation of the impact of this grand demographic event in the reconstruction of the genetic patrimony of contemporary European populations.

Science News in Euskal Herria

This article comes to us thanks to Basqueresearch.com:

Technology, health, information science and the environment are the main topics in science news

Technology in general, health, information technology and the environment were the main topics in science news stories appearing in newspapers published in the Basque Country in the first four months of 2008. This said, the front pages of these dailies give health matters priority, followed by the environment and then technology.

These were some of the conclusions drawn from a research study and published by the Elhuyar Foundation. They analysed 11 daily newspapers (Berria, Deia, Diario de Navarra, El Correo, El Diario Vasco, Gara, Le Journal du Pays Basque, Diario de Noticias, Noticias de Gipuzkoa, Noticias de Alava and Sud Ouest) from the 1st of January to the 30th of April, 2008. The methodology of analysing the profile of science stories in the press was to gather the texts of articles published about science, technology and innovation. 6,448 texts in total were collected and a study of these led to the following conclusions:

Most texts (82%) were published in Spanish, the majority of the newspapers analysed being published in this language. The Vocento Group dailies (the El Correo Español and the Diario Vasco) published most of the articles (932 and 741 respectively); third place in this classification was the Noticias de Gipuzkoa with 715 texts.

Science is not important

Most of the texts published (1,089) were of little importance, according to the Richard Budd scale (space given over to the news, the page the news item appears on and the use of graphics or otherwise), and the number of items of especial importance was only 55.

The research results showed that the topics chosen by journalists in providing information on science, technology and innovation were focused basically on technology in general, health, information technology and the environment.

The daily newspapers usually give mere information — brief news items —, although it could not be said that they totally discard an interpretation of such items.

The study also showed that the dailies do not publish many opinion articles on science, technology and innovation and less so editorial opinion on these matters. In the period under study, the eleven newspapers analysed published only 26 editorials on topics related to science, technology and innovation.

Positive view

However, we can say that these dailies maintain a favourable attitude to science, technology and innovation, although this is not directly demonstrated. Thus, the perspective of most of the news items in these fields is positive, although in journalism bad news tends to have greater possibilities for publication than good news.

Above all, the newspapers publish news stories of an official nature related to science, technology and innovation and which are generally related to the Basque Country or to the European Union; more than half (60%) of the sources for the news stories were government bodies. It also has to be pointed out that 25% of news is of unknown origin (the source of or the person responsible for the item is not known), as the newspapers do not provide this information.

Finally, the topics chosen by journalists in the Basque Country to inform about science, technology and innovation are similar to those selected by their European homologues. Moreover, the problems Basque journalists have in trying to identify the origin/author of the news related to these topics are also those mentioned by European communication media professionals.

Energy Forum at BEC

This note comes to us via EITb:

Bilbao Exhibition Centre to host European Future Energy Forum

09/29/2008

The Centre has been chosen by organizer 'Turret Middle East' to host a meeting which is scheduled to take place next year from the 9th to the 11th of June.

As from 2009, the Bilbao Exhibition Centre is to add another international event to its calendar: the Centre has been chosen by organizer Turret Middle East to host the European Future Energy Forum, the first edition of which is scheduled to take place next year. In the final stage of the selection process, Bilbao completed with Copenhagen, Reykjavik and Frankfurt for the honour of staging the European edition of what has become a strategic event following on from the first World Future Energy Summit in Abu Dhabi (United Arab Emirates) in January this year.

The candidature of the Bilbao Exhibition Centre was part of a package which included support from the Basque government, the Department of Innovation and Economic Promotion of the Provincial Council of Bizkaia, Bilbao City Hall, Bilbao Convention Bureau and Destino Bilbao. The city's selection is made all the more significant by the standard of the other candidates short listed: Germany is Europe’s leading player for renewable energy sources in terms of consumption, output and technological advances, Denmark is the world's leading producer of wind power and Iceland boasts exceptional geological and geothermal resources.

The balance was tipped in favour of Bilbao by the level of investment in the country, the extraordinary recent growth in renewable energy sources, the prominent position of the Basque Country in the field, with strong support from business and institutions, and the success of Gastech 2005, an event which broke records at the Exhibition Centre.

World Future Energy Summit

The first ever World Future Energy Summit featured 220 exhibitors and attracted over 11,000 visitors from 77 countries, including royalty, heads of state, energy and environment ministers, top entrepreneurs and other high-ranking personalities.

In the wake of the success of the summit, and seeking to provide a global benchmark event for policies on energy, investment development and alternative, renewable infrastructures, organising firm Turret Middle East decided to organise a forum outside the Near East every two years, so as to extend the brand to a broader geographical area.

As a result, the Bilbao Exhibition Centre will host a biennial blend of commercial exhibitions and technical seminars on renewable energy sources and their application. This is an area which is undergoing spectacular growth, involving specialists from the fields of energy, architecture and finance.

Organizers with proven prestige

Turret is an English-based firm with broad experience as an event organizer in many different sectors all over the world. It has also maintained links with RAI, DMG and Reed Exhibitions among others, so its representatives work at the highest possible levels. Around 18 months ago it established a subsidiary in Abu Dhabi (to cover the Middle East market), where it has already organised five fairs in the fields of recycling, foodstuffs and renewable energy sources, all of them highly successful. The firm's prestige and track record in organising specialist events means that expectations are high for the success of this fair at the Bilbao Exhibition Centre, aimed at the energy market.

Research on Multiple Sclerosis

This note was published at EITb:

European network to investigate gene causing multiple sclerosis

09/23/2008

Ten research teams will investigate the genetic component of the multiple sclerosis’ treatment, they will do it from the University of the Basque Country.

The University of the Basque Country hosted a conference in which lecturers introduced the European scientific network that will look into the new customized treatments for multiple sclerosis. The talk took place at the so-called “Classrooms of the Experience” located at University’s premises in the old part of Bilbao’s city.

The multiple sclerosis is a chronic neurological disease with no definitive cure. It currently affects 400,000 people in Europe, 2,000 in the Basque Country.

During the presentation it was possible to listen to the Belgian professor Koen Vandenbroeck ‘s speech. Vanderbroek is a scientist that works for Ikerbasque, a Foundation created by the Basque Government that primarily aims to help develop scientific research in the Basque Country by attracting researchers and helping them establish themselves in the field of research. Belgian researcher will be the main coordinator of the study.

A European scientific network will investigate the genetic component of the multiple sclerosis’ treatment and it will do it from the Basque University. Ten research teams from five different countries will work on a 2, 3 million Euro-project during four years. The aim is to use genetics to advance towards a customized medication.

The project also offers training internships intended for young researchers.

Measuring Winds in Venus

This note comes to us thanks to the Basque Research page:

Team led by scientists from University of the Basque Country manage to measure wind details of Venus

Venus is a planet similar in size to the Earth. Nevertheless, it is quite different in other aspects. On the one hand, it spins very slowly on its axis, taking 224 terrestrial days and, moreover, it does so in the opposite direction to that of our planet, i.e. from East to West. Its dense atmosphere of carbon dioxide with surface pressures 90 times that of Earth (equivalent to what we find at 1000 metres below the surface of our oceans), causes a runaway greenhouse effect that raises the surface temperatures up to 450ºC, to such as extent that metals like lead are in a liquid state on Venus. At a height of between 45 km and 70 km above the surface there are dense layers of sulphuric acid clouds totally covering the planet. It was in the 1960s that they discovered, by means of telescopic observations, that the top level of cloud layers moved very rapidly, orbiting the planet in only four days, compared to the planet’s own orbit of 224 days. This phenomenon was baptised the “superotation” of Venus: the winds carrying these clouds travel at 360 km/h.

The various space missions that explored the planet in the 70s and 80s showed that the “superotation” was a permanent phenomenon and, moreover the probes that descended through its atmosphere indicated that, in a number of places, the winds decreased in speed to zero at Venus’s surface. New observations carried out with the Venus Express mission of the European Space Agency, in orbit around Venus since April 2006, have enabled the team of scientists from the University of the Basque Country (UPV/EHU) to determine in detail the global structure of the winds on Venus at its level of clouds while, at the same time, to observe unexpected changes in the wind speeds, and which will help to interpret this mysterious phenomenon. The team was led by Agustín Sánchez Lavega with team members being Ricardo Hueso, Santiago Pérez Hoyos and Javier Peralta, from the Planetary Sciences Group at the Higher Technical Engineering School of Bilbao. The article, entitled “Variable winds on Venus mapped in three dimensions”, was published with front page coverage in the Geophysical Research Letters. This journal is published by the US American Geophysical Union (AGU) and is the most prestigious in its sphere of research. Moreover, the article was one of eight selected amongst hundreds for publication by the AGU in all journals as being the most outstanding in the EOS Transactions bulletin – sent to 50,000 AGU members at research centres all over the world.

Novel aspects of the rotation

Using images recorded by both day and night on Venus with the VIRTIS spectral camera on board the Venus Express, the UPV/EHU scientists have succeeded in measuring these clouds over several months and have discovered new aspects of the “superotation”. Firstly, between the equator and the median latitudes of the planet there dominates a superotation with constant winds blowing from East to West, within the clouds decreasing speed with height from 370 km/h to 180 km/h. At these median latitudes, the winds decrease to a standstill at the pole, where an immense vortex forms. Other aspects of the superrotation that observations with VIRTIS have made possible are that the meridional (North – South) movements are very weak, about 15 km/h, and, secondly, unlike what was previously believed, the superotation appears to be not so constant over time: “We have detected fluctuations in its speed that we do not yet understand”, stated the scientists. Moreover, for the first time they observed “the solar thermal tide” effect at high latitudes on Venus. “The relative movement of the Sun on the clouds and the intense heat deposited on them makes the superotation more intense at sunset than at sunrise”, they stated.

“Despite all the data brought together, we are still not able to explain why a planet than spins so slowly has hurricane global winds that are much more intense than terrestrial ones and are, moreover, concentrated at the top of its clouds” stated Mr Sánchez Lavega. This study has enabled advances to be made in a precise explanation of the origin of superotation in Venusian winds as well as in the knowledge of the general circulation of planetary atmospheres.


Remember, I always dedicate the posts about science and research in Euskal Herria to Keith Johnson who once said that Basques could never excel in science because they speak a language suited only for sheepherders.

More Basque DNA Research in Boise

This note comes to us via Boise's 2News:

Basque students gather DNA in the West

By Associated Press

BOISE (AP) - The research station was simple, a folding table parked on the front lawn of a small brick house that sheltered some of the first Basque sheepherders to immigrate to Idaho in the early 1900s.

But then Adrian Odriozola explains why he's traveled about 5,300 miles from his home in Spain to be here, at a Basque festival in downtown Boise, and it gets quite a bit more complicated.

"We are trying to improve the health of the population," said Odriozola, a doctoral student from the University of the Basque Country in Spain.

Odriozola was sent to the United States in early July to collect DNA samples from descendants of the Basque families that left their historically troubled homeland, where the Pyrenees Mountains separate Spain from France, and immigrated to a states such as Idaho, Nevada and California.

The goal: Collect enough DNA to support one of the most comprehensive genetic maps of the ethnic minority.

The University of the Basque Country is funding the research and hopes to explain why large portions of Basques living in their homeland suffer from diseases such as Alzheimer's and Parkinson's, and learn why diabetes is more prevalent among Basques living in the United States.

Odriozola and his research partner, 27-year-old history student Eneko Sanz, spent several weeks at festivals in California, Nevada and here in Idaho, where some 15,000 Basques live and make up the third-largest population in the world, behind Argentina and the Basque homeland on the Spanish-French border.

"Sometimes, it's difficult," Odriozola said, "at a festival people want to party."

The day was still early when he stationed himself at his makeshift research station at the San Inazio Basque Festival in Boise. Odriozola surveyed the block of bars and restaurants, a neighborhood where Basque descendants congregate each year to honor Saint Ignatius.

The Boiseko Gasteak Basque Dancers wouldn't perform for several more hours. Clear plastic cups were filled, for the most part, with nonalcoholic drinks.

And Odriozola, a 26-year-old foreigner who would spend the day persuading Basque descendants to gargle a vial of pink, cinnamon flavored mouthwash and fill out a 50-question survey about their health, was optimistic.

"This will be our strong day," he said.

As the festival rolled out live music, food and dancing, and then waned into the evening, Odriozola and Sanz had collected nearly 100 samples from people like Louise Murgoitio Gunderson. Her grandparents immigrated from the Basque homeland near the end of the 1800s.

"It was a hard life in Spain," said Gunderson, a 56-year-old budget officer with the U.S. Attorney's Office in Boise.

She swigged down the pink vial of mouthwash, swished it around in her mouth for 10 seconds, and then spit the liquid back into the clear vial before she started filling in a detailed survey about her and her family's health. Did any of her relatives have a blood disorder? What about tumors? Skin diseases?

The process took about 10 minutes and Gunderson became "USA169-BOIDV2" in the study, where names are kept anonymous and vials will be identified by coded stickers and studied at a DNA bank at the University of the Basque Country.

There, researchers will try to determine whether environment or genetics played a role in how Basques descendants developed diseases such as Alzheimer's, Parkinson's and diabetes.

But first, the samples will be processed at a lab at Boise State University, where graduate student Mike Davis is also studying Basque DNA for his master's thesis. Davis helped Odriozola and Sanz gather DNA in Idaho.

Altogether, the team collected about 400 samples from Nevada, California and Idaho before Odriozola and Sanz left the United States in late July to return to Spain to process the data they've collected so far. The pair will travel to Latin America later this year to collect more DNA samples.

Few migrant populations present such a perfect test case for explaining whether genetics or the environment is a bigger factor in why large numbers of Basque have developed certain diseases, Davis said. The Basque offer a tight-knit population, essentially identical when it comes their DNA, but living in two different countries.

"They've always had this sort of mystery about them," Davis said, "their language, nobody really knows where it came from."

Linguists and historians haven't been able to define the origin of the Basque language, called Euskera, and it has no definite link to any other widely spoken tongues in Europe, said John Bieter, acting director of the Basque Studies Center at Boise State University.

"This leaves the Basque as kind of a mysterious group," Bieter said, "studying their DNA may be one way to unravel that mystery."

The AP finally acknowledges the Basque people as an ethnic group, that's a first one.

The US West's Basque Legacy

This article comes to us thanks to the Baker City Herald:

Speaker outlines Basque sheepherders' legacy in the West

Published: August 13, 2008

By MIKE FERGUSON

Baker City Herald

In the early 1970s, Kent McAdoo joined a group of Nevada-based Basque sheepherders for 13 months to study the effects coyotes were having on the large flocks tended by Basques.

On top of his predation research, McAdoo came away with a deep appreciation of the sheepherders, who came to this country from their homeland in the Pyrenees Mountains that separate Spain and France.

"They had a penchant for hard work, a dedication to the task at hand, strong entrepreneurial skills, and they've left an indelible imprint on the High Desert" of Northern Nevada, Southern Idaho and Eastern Oregon, McAdoo told a crowd of about 45 Saturday evening at the Baker Public Library. "I met a lot of very interesting characters."

McAdoo, who works for the Nevada Cooperative Extension, came to Union and Baker counties last week as part of the Libraries of Eastern Oregon's "Sense of Place" series sponsored by the Institute of Museum and Library Services.

McAdoo called his hour-long presentation "Basque Herders: The End of an Era." While 90 percent of the herders who worked their flocks in the High Desert in 1970 were Basque, their numbers had shrunk to 14 percent of all herders by 1976.

McAdoo thinks he knows why: Francisco Franco, the Spanish leader who "kept his thumb on the Basques," died in 1975, and many Basques returned home as soon as they could following the death of Franco and the expiration of their work contract.

"I wasn't in there when (Franco) died," McAdoo said, "but I guarantee you throughout the region there was a big celebration going on. It changed their lives."

The Basque presence changed the region and changed McAdoo, too.

"In our part of the country, many small towns have celebrations" of Basque culture, he said. "Elko (Nevada) draws between 8,000 and 10,000 every year to watch people lift weights and chop wood. It keeps the culture alive even though the sheepherders are gone from the face of the landscape.

"To me that is kind of sad," McAdoo said. "I mourn the loss of their culture. I know when I was working with them that they were something special, but the impact they had was something I took for granted."

Sheepherders from the old country

Basques began moving to the American West in the 1850s. Many, according to McAdoo, "were sheepherders in the old country."

With the 1934 passage of the Taylor Grazing Act, formal sheep and cattle operations were put in place. Many operations were owned by Basques, who used the option of taking part of their payment in "bummer," or orphan lambs, as a way to build up their herds.

The herders McAdoo studied worked hard. Their contracts specified just one day off every year — for the sheepherder to celebrate his birthday.

The men McAdoo lived among followed the Goicoechea Trail, lambing just north of Elko, Nev., then driving the sheep up to summer range just south of Mountain Home, Idaho.

Sheep do indeed play follow the leader, McAdoo noted: one slide he displayed showed a pair of sheep jumping over nothing in particular after they'd seen their leader jump over a clump of sagebrush.

"I'll bet 90 percent of them jumped over nothing, too," McAdoo said with a laugh. "I must have taken a whole roll of film."

The sheepherders were up by 4 o'clock each morning to cook breakfast and boil coffee.

"I learned to pour coffee over rich, thick sheepherder bread with condensed milk," McAdoo said, smacking his lips at the memory. "I got so I liked it pretty well."

The country the sheep and the shepherds traversed is steep, "but these guys are used to it," McAdoo said. They never trucked their sheep, instead slowly working them along a common trail.

"The sheep aren't pushed intensively," McAdoo said. "It's better for weight gain and better for the trail."

To McAdoo's consternation, every day a herder would count the 60 or 80 black sheep among the 7,000-member herd. Why spend time every day counting such a tiny minority, he wondered.

He learned that the Basques figure if one black sheep is missing, that means 100 or more white sheep are missing. If two or three black sheep are missing, time to drop everything and find the hundreds of lost white sheep.

"It was not just a ritual," McAdoo said.

The men clearly had time on their hands, which often led to endless debate, McAdoo said.

"They would melt snow for their horses, and a big topic (of conversation) was not to burn the water so it takes on the metallic taste of the tub," he said. "That conversation took hours."

The Basque language is notoriously difficult to learn — and here are examples why: "etxekoandrea" means "housewife." The number "77" is rendered "Iruetamarzazpi."

"Their language is 75 percent unrelated to any other language, and 25 percent related to Latin languages," McAdoo said. One linguist, he said, found a connection between the Basque language and the language spoken in strife-torn Georgia.

During his 13 months of study, McAdoo met only one sheepherder who could read and write his native language. The afore-mentioned Franco wouldn't let Basques speak their own language on the streets, nor would he allow it to be taught in schools.

"People weren't literate," McAdoo said, "in the language they spoke every day."

In the early 1970s, shepherd pay began at $350 per month, and the rancher bought all the shepherd's clothes and food, "and some of their whiskey and all of their wine," McAdoo said.

"These guys saved money like you wouldn't believe," he said. "Remember, they only had one day a year (their birthday) to spend their money in town."

Nowadays, McAdoo said, sheepherders in Western states come from many different nations, including Mexico, Chile, Peru and China. They, too, are willing to work hard for very little money, he said.

One thing McAdoo has learned to do when he offers his presentations is to say the place names and family names involved in the stories he's telling.

"I pronounce their names because people know them," he said. "This is a very tightknit community, and they have relatives throughout this region."

With that, McAdoo flashed one last message in the Basque language: "Eskerrik asko!" or "Thank you very much!"

Basque DNA Research in Boise

This not comes to us via Idaho News Now:

Researchers gather DNA from Idaho Basques

by Ysabel Bilbao

BOISE -- Idaho’s largest ethnic group will be celebrating this weekend on Boise’s Basque block.

While a festival for some, it will be an experiment for others.

This block will fill with people for the annual San Inazio Basque Festival.

While Basques enjoy the celebration, two research students from the University of the Basque Country will be gathering DNA for medical research.

For many the Basque Center is a place to have a drink with friends, but this week it’s turned into part bar and part research lab.

Ph.D. students from the University of the Basque Country, Adrian Odriozola and Eneko Sanz, are taking DNA samples from local Basques as part of a worldwide research project.

The two have gathered samples from hundreds of Basques living in Idaho, Nevada, and California.

Each person gargles a liquid, which collects cells from the sides of people’s cheeks.

From the back of the bar their work is then transferred to a lab at Boise State University.

It's here under the guidance of Dr. Greg Hampikian, that Odriozola and his American counterpart Michael Davis extract DNA samples.

"We are trying to establish a collection of Basque Community DNA around the world. And in Boise there are a lot of Basque in Idaho, it's a strong DNA, Basque community," said Odriozola.

It's that strong community and strong genetic link to the old country that has drawn the researchers abroad. Dr. Hampikian says the best form of genetic research comes from twins separated at birth. Studying their DNA helps researchers know if disease or illness comes from nature or nurture.

Studying the Basque here and in their homeland provides that on a much larger scale.

"Finding two populations that have the same genetics that are located in different places is a huge benefit to all of humanity," said Hampikian.

The research students are focusing their studies on Alzheimer’s and Parkinson’s diseases, but their research will include a variety of illnesses, including heart disease, cancer and diabetes.

"We want to establish a strong collection about the Basque community, not only for use in DNA Bank, we want to offer this to the scientific community," said Odriozola.

"These types of studies are ongoing, not just with Europeans or the Basques, but really a worldwide phenomena," said Michael Davis, BSU graduate student.

The Basque researchers will leave Boise next week and head back to the Basque country to input data.

Afterward, they will continue traveling to Central and South America to collect DNA samples from Basques living there.


My only question is, are you to do this before or after your first kalimotxo?

How Trees Protect Themselves

This article about some recent research conducted in the Basque Country regarding how trees (and plants in general) protect themselves during harsh times comes to us thanks to Basque Research:

Measuring the stress of forested areas

Plants undergo stress because of lack of water, due to the heat or the cold or to excess of light. A research team from the University of the Basque Country have analysed the substances that are triggered in plants to protect themselves, with the goal of choosing the species that is best suited to the environment during reforestation under adverse environmental conditions.

Droughts, extreme temperatures, contamination, and so on – all are harmful to plants. On occasions, the damage is caused by humans. For example, as a consequence of cutting down trees, plants used to shady conditions may be exposed to an excess of light. However, in most cases it is nature itself that causes the stress. In spring, plants have sufficient average humidity and temperatures, i.e. what scientists deem ‘optimum conditions’. But in winter they have to withstand considerable cold and in summer, on the other hand, high temperatures and droughts: adverse environmental factors that generate stress situations. Thus, in winter and in summer, the light which under normal conditions would be a source of energy becomes excessive, given that the metabolism of the plants under these conditions is not able to assimilate it. This process is known as photo-oxidative stress.

Some plants are incapable of withstanding this stress – unable to dissipate the excess energy, generating a chain reaction by which they deteriorate and die. Other species, on the other hand, undergo processes of acclimatising themselves to the new situation and trigger chemical compounds that act to protect them. These species are the object of interest of a research team from the Department of Plant Biology and Ecology at the Faculty of Science and Technology of the University of the Basque Country (UPV/EHU). The members of this team – called EKOFISKO and led by Dr. Txema Becerril – are studying the plants’ defence mechanisms in order to predict damage before it is produced. They measure the photo-protector substances created by the plants and analyse their behaviour, using them as biosensors of photo-oxidative stress.

Amongst all these plants, they have been studying trees and other forest species, given that they are long-cycle species and it is important that they acclimatize correctly to the environment before reforestation is embarked upon. The autochthonous species of the Autonomous Community of the Basque Country (CAPV), especially the southern part thereof, being where the two climatic regions - the Atlantic and the Mediterranean – meet, would be the first to suffer the consequences of climate change. The study mainly involves species with ecological, economic or landscape interest, and analyses both the deciduous species and the perennial varieties; particularly the latter as they withstand the cold winter temperatures without shedding their leaves.
On the trail of the box tree

The box is a model species and a good example for analysing the defence mechanisms of plants: it is capable of withstanding quite different environments (both dry and sunny climes as well as damp and shaded conditions), thanks to its resistance and adaptability. When it is under stress, the leaves go red, as other species do in autumn, but its peculiarity is that it is able to convert its chromoplasts (where the red pigments accumulate) into chloroplasts (with green pigments) and once again capture energy when the stress conditions disappear.

In order to measure the biomarkers of photo-oxidative stress the research team also simulated the winter or summer conditions in the greenhouse and in the growing rooms at the Faculty of Science and Technology, i.e. they artificially induced in the plants the conditions which they would have to be subjected. This makes it possible to isolate each one of the stress agents and to study its consequences, leaving aside the rest of the variables found in nature.

According to what the research team at the UPV/EHU have shown, the secret to being the most adaptable species lies in accumulating antioxidants, such as vitamin E and special carotenoids (carotenes and xantophylls); precisely the substances that provide colour to plants. On receiving too much light, the VAZ cycle is triggered and the balance between three xantophylls (corresponding to these 3 initials) is altered so that the excess energy does not harm the plants. The human body, for example, is not capable of creating these highly important substances itself and it has to ingest vegetables in order to obtain antioxidants (from plants). Besides studying the VAZ cycle, Mr Txema Becerril’s team has contributed to the discovery of a new cycle (the lutein epoxide cycle), present in many forest species such as beech, laurel, holm oak or oak and the team is currently studying what exactly is its protective function.


I personally dedicate this post to Keith Johnson and his claim that the Basques were unable to conduct any such research because they were being educated in Euskera.

Magnetic Shape Memory Alloys

Magnetic Shape Memory Alloys to create robotic claws with nanometer precision

Robotics

May 26, 2008 Researchers at the University of the Basque Country have used ferromagnetic shape memory alloys to develop experimental devices that can position objects with an incredible accuracy of 20 nanometers. The devices do not consume energy after being put in place, and have applications ranging from medical science to positioning mirrors in high-power telescopes.

Shape memory alloys are metals that, after being bent, are triggered to return to their original state after being heated. The phenomenon was first observed in 1932, but it was only with the commercialization of the Nickel-Titanium alloy, or nitinol, that their applications were properly explored. Researchers at the Ohio State University have proposed using nitinol instead of stainless steel when reconstructing broken bones – the urge of the metal to return to its form exerts a constant pressure on bones, forcing them to stay in place. Stiquito, a small robot often used in university courses, uses the expansion and contraction of nitinol as a method of propulsion.

However, ferromagnetic shape memory alloys only transform back to their original configuration when exposed to a magnetic field. Since the application of the field is instant, the transformation is also rapid, as compared to the gradual heating and cooling of metal in regular shape memory alloy transitions. Ferromagnetic shape memory alloys do not exist commercially, and are currently only created as part of research.

The Automation Group at the Department of Electricity and Electronics of the Faculty of Science and Technology at the Leioa campus of the University of the Basque Country (UPV-EHU) is studying the stimulus-response characteristics of shape memory alloys and ferromagnetic shape memory alloys, with the aim of using them to facilitate precise movements in electrochemical systems in robotics. The researchers used shape memory alloys to build a prototype of a lightweight gripping claw - nitinol wire was placed between two elastic metal sheets, which contracted when a current was applied to the wire, gripping any objects around it. The claw has a point of precision to within a micron. The University hopes to further refine the ferromagnetic shape memory alloy actuators, which are already precise within 20 nanometers.

All these devices, currently at a laboratory stage, are useful for testing the basic characteristics of the materials, but in the future they could be end-product commercial prototypes for robotic devices and in micro and nanopositioning.

DNA Research at Aldaieta

This article was published at Innovation Reports:

Ancient DNA: reconstruction of the biological history of Aldaieta necropolis

A research team from the Department of Genetics, Physical Anthropology & Animal Physiology in the Faculty of Science and Technology at the Leioa campus of the University of the Basque Country (UPV/EHU), and led by Ms Concepción de la Rúa, has reconstructed the history of the evolution of human population and answered questions about history, using DNA extracted from skeleton remains.

Knowing the history of past populations and answering unresolved questions about them is highly interesting, more so when the information is obtained from the extraction of genetic material from historical remains. An example is the necropolis at Aldaieta (Araba) where some of these mysteries about these peoples have been answered – thanks to the study of their DNA.

Aldaieta brings together certain important features which make this site a prime archaeological and historical record and its conservation an important task of restoration and study. In this vein, the Department of Genetics, Physical Anthropology & Animal Physiology in the Faculty of Science and Technology at the University of the Basque Country (UPV/EHU), has undertaken a study of DNA in the necropolis at Aldaieta (Araba).

The researchers at the UPV/EHU have been studying the genetic material of ancient remains, extracted both from bones and teeth, in order to interpret the biological and social meaning of this necropolis. The study of ancient DNA is a field in which laboratory work is enormous for a number of reasons. On the one hand, in comparison with modern or current DNA, that extracted from the bones and teeth is quite degraded and is in very small quantities. As a consequence, the risk of contamination is high. This is why, at all times the results obtained have to be authenticate and it has to be demonstrated that they are not due to contamination or handling/manipulation, but have genuinely been obtained from the samples.

The research work began with the extraction and subsequent analysis of DNA from the ancient remains (normally by the sequencing of mitochondrial DNA, a molecule inherited maternally) of each individual and in duplicate. Moreover, a third copy of the sample from each individual was sent to another laboratory and. finally, they compare all of them in order to distinguish between what is endogenous from what is the result of handling. Obviously, the results obtained from the same sample/individual have to tally in all the analyses in order to be reliable.

Interpretation of the settlement at Aldaieta

Despite the problems inherent working with ancient DNA, the methodology drawn up for the current work as well as the precautions and criteria of authentication undertaken have enabled reliable and verifiable results of the population buried at Aldaieta to be obtained.

Within the great homogeneity of the mitochondrial lines on the European continent, the genetic substrate of the population buried at Aldaieta falls within the variability of that expressed by current populations on the Cantabrian coast and Atlantic axis, thereby indicating the existence of genic flow between these human groups in ancient times.

Besides the characterisation of the mitochondrial genome, they have carried out the characterisation of the chromosome Y, using techniques focused on ancient DNA, an have shown the existence of family relationships within the necropolis, given that certain mitochondrial lines have a particular distribution, the grouping of individuals belonging to the same line having been discovered at nearby burial sites. Besides, there exists a significant differentiation gender wise, men having qualitatively and quantitatively more important funerary artefacts than women.

It is clear that the genetic analysis of skeleton remains, despite the labour-intensive work involved and the problem of authenticity of the results, has provided an essential contribution in the reconstruction of the biological history of human populations.
