Recognized Research Group (IRG) Industrial Telematics, University of Valladolid working to develop software for the recognition of scenes. The system is based on artificial vision technology that uses video cameras and computers to process digital images captured, and on neural networks, computer processes that mimic the observed properties of biological neural models as a detailed to DiCYT Francisco Javier Diaz Pernas, Professor, Department of Signal Theory and Communications and Telematics Engineering and member of the group.
The software serves, for example, to select certain images in a huge database, which is especially important if one thinks of the Internet. “The system is very convenient if you want to search for images with certain components, like it has a landscape, to include in a document or make a report,” says the researcher, who points out that with the software they develop “through networks neural and other processes associated “can be detected within the image bank of the scenes that have the characteristics required.
In this sense, the group works in the processing of the neural architecture for segmentation and recognition of images of natural scenes, which allows to define significant regions within a scene, in the detection and tracking of body parts and bio-architectures insipiradas in the Human Visual System (SVH), those “who somehow behave similarly to the human system.

Should we allow commercial hunting of whales to reduce the catch? The question is raised by a committee of the International Whaling CommissionA few months of the IWC meeting in Morocco, who will try to end the conflict between supporters of an outright ban and the three countries, Japan, Iceland and Norway, which still practice whaling despite the moratorium decided More than twenty years.
The Washington Post pointed out Tuesday that the whale catches are increasing. In 1990, three hundred were slaughtered. Ten years later, catches have increased to 1,000 animals per year, a figure that has nearly doubled over the last five years! In short, the moratorium does not work. Reasoning taken by the “Small group” of the International Whaling Commission, which released a proposal to be discussed in early March. It expects to end the moratorium for a period of ten years, but by imposing a substantial decrease in the number of whales killed each year. Since 1985, the year of entry into force of the moratorium, 33,000 whales were killed, the report confirms. Jurists, members of the working group did not give figures on the quota could be decided in an agreement at the meeting in Morocco … While a portion of Antarctica is in principle prohibited whalers The working group proposes to create a second in the South Atlantic.

Obtained using carbon, hydrogen, oxygen, silicon and molded to form a nanoscopic tip, the material has significant implications for technological applications
Researchers at the University of Pennsylvania and Wisconsin at Madison, United States, together with colleagues from IBM Research in Zurich, Switzerland, have developed a tip extrasottile carbon with a wear resistance at nanoscale, 3000 times greater than the silicon.
The end result is a material similar to diamond: its wear was estimated at one atom per micrometer of slipping on a substrate of silicon dioxide, far below that of a tip generated by the same dioxide, which is still the most advanced solution.

Only seven species of mammals, all rodents, have an unusual mechanism of sex determination which involves the development of fertile females with XY chromosomes
In mammals, sex determination generally follows a very simple rule: If you have XX chromosomes develops a female with XY chromosomes develops instead a male. In situations where there is a deviation from this principle speaks of chromosomal abnormalities that often cause infertility. On the Y chromosome, sex is determined by the presence or absence of a single gene, called Sry, Identified in 1990. This gene triggers the development of masculine characteristics, while in his absence the gonads become ovaries.
Only a few species of mammals are beyond the rule, have hitherto been known only seven, all belonging to rodents.

The tidal forces generated by the gravity of its star to the planet have taken a form that is more like that of a rugby ball than a ball
An extra-solar planet massive, WASP 12-b, is about to be destroyed by his own star: the shows A study published in the journal Nature conducted by researchers at Peking University and the University of California at Santa Cruz.
“It ‘the first time astronomers have witnessed the destruction of incipient or the goal of a planet to their own death,” said Douglas NC Lin, co-author of the study and director of the Kavli Institute for Astronomy and Astrophysics (KIAA) in Beijing.

The mating of females with multiple partners, studied in populations of fruit flies, reduces the risk of extinction of the population effect of offspring without males
Promiscuous females may be the key to the survival of some animal species: So says a new research result of the collaboration of the Universities of Exeter and Liverpool, United Kingdom and now published in the journal Current Biology.
The study could thus solve the mystery of why the females of most species have multiple partners, although such behavior is risky for individuals. Known as polyandry, the phenomenon is indeed widespread in many species, from insects to mammals.

English, Japanese, American, Indian, German – all working flat out on one goal: to develop a cancer treatment that is tailored exactly to the genotype of individual patients. The radiation and chemotherapy, with their devastating side effects could thus be unnecessary in the future.
Cancer is a disease of genes. A person becomes ill from flu, you know that it has spread a virus. He becomes ill with cancer, his heritage has been damaged. Tobacco smoke, ultraviolet light have, the age or the fate of traces in the DNA and mixed up the sequence of their components.
To get it under control, U.S. and British scientists have launched four years ago, a company that will cost billions of euros. This company has evolved into a global medical research laboratory, the largest cancer research project ever. The International Cancer Genome Consortium (ICGC) now set about to collect the 50 major cancers, all changes in the genome and analyze.

The aspects of marine environmental protection that were not regulated by Spanish legislation are addressed in the draft Law on the Protection of the Marine Environment that the Government has introduced this morning. The bill, approved by the Council of Ministers will also address the policy planning in the marine environment, the incorporation of the EU framework directive on this matter, and the creation of Marine Protected Areas Network.
Establishing a legal framework in the marine environment will allow your protection, good condition, and preservation, and the recovery of marine ecosystems and the prevention and elimination of environmental pollution in these environments.
The key elements of Bill’s Marine Environment Protection Strategies are the Marine as a planning tool, the creation of Marine Protected Areas Network and the incorporation of environmental criteria in the uses of the marine environment.
For this reason, Spain delimit a series of marine boundaries in the specific actions to be carried out according to certain Marine Strategies for each of them.

A method of genetic engineering allows the incorporation of unnatural amino acids in a protein. What produce artificial proteins?
Produce Is there one day will of proteins do not exist in nature and endowed with special properties? The team of Jason Chin, Laboratory of Molecular Biology Medical Research Council, Cambridge, United Kingdom, opens up unimagined. She has developed a system capable of producing proteins incorporating combinations of unnatural amino acids in predetermined positions.
In cells, proteins necessary for the functioning of the body are manufactured by ribosomes. These molecular machines interpret the “sentence” consisting of the following “letters” A, C, T and G which make up a gene, and sent a messenger RNA in order to synthesize a protein made of a string longer or shorter amino acids.

A recent study conducted by researchers at the Centro de Biologia Molecular “Severo Ochoa” (CSIC-UAM), Universidad Autonoma de Madrid, addresses the question of how the virus of African swine fever takes control of the cell and prevents the same counter viral infection.
It is known that viruses are intracellular parasites able to employ different strategies to control and interfere with cellular mechanisms of defense against infection. One strategy is to hijack the cellular machinery of protein synthesis. Thus, the virus saves the energy of the cell to synthesize its own proteins, and prevents the infected host antiviral synthesize those molecules that could counteract the viral infection.
However, the molecular basis of the mechanisms used by viruses to carry out this type of phenomenon is still not determined.
