New data about the connection between the Mediterranean and the Atlantic

The magazine ‘Science’ publishes the first results of a research at the Gulf of Cádiz in which José Abel Flores and Francisco Sierro of the University of Salamanca participated

Between November 2011 and January 2012, the most important oceanography research ship in the world, the Joides Resolution, sailed through Gulf of Cádiz and the coast situated in the South of Portugal searching for marine sediments which could help to explain the history of water exchanges between the Mediterranean Sea and the Atlantic Ocean through the Strait of Gibraltar, a phenomenon with numerous implications in the study of climate. Since then, scientists have been analyzing data and, as a result, the magazine Science publishes this expedition’s first results, in which José Abel Flores and Francisco Sierro, researchers of the University of Salamanca participated.

Genomes of two spiders offer new information about venom and silk production

The scientists have sequenced the genomes of a Brazilian and an African spider, data that have pharmacological applications in the case of venom, and in the field of biomaterials in the case of silk.

Danish, Chinese and Saudi researchers have sequenced the genome of two spider species: the Brazilian one called tarantula with “white knees” Acanthoscurria geniculado and the African spider called terciopelo Stegodyphus mimosarum. The data have contributed with information about genes and proteins related to venom and silk production, information which could be applied in the pharmacological field in the case of venom and in the biomaterials field in the case of silk.

Only 16% of Ph.D.s work in the private sector in Spain

Half the OECD average

Spain produces Ph.D.s at levels comparable to other countries in its situation. However, a minimum percentage of these degree holders work in the private sector, which entails problems for funding research. This is one of the conclusions of the study El empleo de los doctores en España y su relación con la I+D+i y los estudios de doctorado (Employment of Ph.D.s in Spain and its relation to R+D+I and doctoral studies),carried out by professors at the Universidad Carlos III de Madrid (UC3M) and promoted by the Conference of Social Councils.

Fossil crocodile discovered with remains of another crocodile in its abdominal cavity

A finding made in northeastern São Paulo State indicates that the reptile may have devoured related species

A previously unknown specimen of fossil crocodile, with the remains of another crocodyliform specimen in its abdominal cavity, has been discovered in the General Salgado region of northeastern of São Paulo State. This is the first time that the abdominal contents of a fossil crocodile have been unequivocally identified, proving that these animals sometimes preyed on individuals of other species of the same group. A detailed description of the finding has been published in the scientific journal PLOS One.

New orchid species located in Panamá

'Lophiaris silverarum' was formally described by Germán Carnevali, a Mexico-based orchid expert

Since she was child, Katia Silvera would hike the remote forests of Panama and collect plants with her father, Gaspar, who operates a small orchid company. On one such hike about eight years ago, the father-daughter team collected an orchid that turned out to be new to science. It was just named in their honor.

Gigantic Explosions Buried in Dust: ALMA Probes Environment around Gamma Ray Bursts

This work will appear in the journal Nature on 12 June 2014 and is the first ALMA science result on GRBs to appear

Japanese observations from the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time directly mapped out the molecular gas and dust in the host galaxies of gamma-ray bursts (GRBs) — the biggest explosions in the Universe. In a complete surprise, less gas was observed than expected, and correspondingly much more dust, making some GRBs appear as “dark GRBs”. This work will appear in the journal Nature on 12 June 2014 and is the first ALMA science result on GRBs to appear. It shows ALMA’s potential to help us to better understand these objects.

Protein map of swine seminal plasma developed

Swine semen is one of the most difficult to cryopreserve. The discover could be used to find a way of maintaining these cells stable for a long time

Although domestic swine seminal plasma (a semen fraction) proteins had already been identified, a map of some of these proteins had not been yet produced. A UNal zootechnician obtained a protein map. The project developed was part of the doctorate thesis work of Verónica González Cardona, a UNal alumnus who has recently returned to Colombia after completing her graduate work in Brazil.

Organic amendments modify action of pesticides

IRNASA has studied the effect that organic residues have in herbicide, fungicide and insecticide behaviors

The low content of organic matter of some agricultural soils makes the farmers use organic residues to increase their fertility and obtain better harvests. They need to make use of pesticides to fight insects, fungi or weed simultaneously. The Institute of Natural Resources and Agrobiology of Salamanca (IRNASA, center of CSIC) has studied the effect of combining different organic amendments with many pesticides which may cause contamination problems if not applied correctly.

The inhibition of a family of proteins helps to fight chronic myeloid leukemia

A team of researchers of IBSAL has found a new therapeutic target cell, a discovery that may help to develop a complementary therapy to the current one, according to a work published at ‘Clinical Cancer Research’

A team of researchers of Biomedical Research Institute of Salamanca (IBSAL) has identified a family of proteins called NADPH oxidases that could be a good therapeutic target cell to fight chronic myeloid leukemia. Even though this type of cancer is caused by an oncoprotein for which there are treatments already, until now, scientists have been able to control the disease, but not heal it. They think that combining the existing therapy with inhibitors of this family of proteins will produce good results, just like cellular cultures and animal models have already confirmed.

Collecting bacteria in the marine abyss at depths of more than 10.000 meters or in extremely arid deserts at heights of up to 5.000 meters is the strategy behind the field work conducted by researchers at the School of Biosciences of the University of Kent in the United Kingdom.

ALMA upgrade to probe supermassive black hole

Once assembled, the EHT -with ALMA as the largest and most sensitive site- will form an Earth-sized telescope with the magnifying power required to see details at the edge of the supermassive black hole at the center of the Milky Way

Scientists last week carried out a major upgrade to the Atacama Large Millimeter/submillimeter Array (ALMA) by installing an ultraprecise atomic clock at ALMA’s Array Operations Site, home to the observatory’s supercomputing correlator. This upgrade will eventually allow ALMA to synchronize with a worldwide network of radio astronomy facilities collectively known as the Event Horizon Telescope (EHT).

Found in Atapuerca a case of rickets and scurvy 5.000 years ago

It is a child who, in spite of one’s short life (the death has been estimated at about 7 years of age), suffered from many nutritional problems due to the lack of vitamins

Members of the Research Team of Atapuerca (EIA) and of the University of Burgos have just published in the magazine Journal of Anthropological Sciences the best documented case of rickets and scurvy in Prehistory. The discovery has been made based on a child-like skeleton in an excellent state of preservation located in the site of El Portalón de Cueva Mayor two seasons ago. The researchers have applied the Carbon-14 dating method and have estimated that the remains belong to a boy or a girl who lived from 5,020 to 5,030 years ago.

Boat noise in Bocas potentially harmful to dolphins

New research by visiting scientists at STRI’s Bocas del Toro Research Station shows that noise from boat motors alters the way bottlenose dolphins communicate while foraging

Panama’s once-sleepy Bocas del Toro Archipelago is an increasingly popular destination for tourists. Attractions include dolphin-watching tours around the mangrove cays of the Caribbean getaway. While the dolphin population of Bocas is relatively small — about 200 individuals — a boat tour can almost guarantee a close encounter with the charismatic creatures. Not surprisingly, dolphin-watching boat traffic has increased exponentially in recent years.
