The Executive Director of the company Aiplex Software has admitted attacks or DoS type attack by Denial of Service [1] against websites hosting links to illegal download format Torrent.

Girish Kumar Aiplex Software company based in India, said his company offered its services to the film. Having identified sites hosting links to downloads, a message is sent to the company responsible if the links are not disabled, the company launched its attack. In his films in India generally leave on Friday morning at 10:00 in the afternoon and once they are available for download.

DoS attack types allow you to block access to an Internet site by flooding the server with millions of simultaneous requests. According to these estimates 95% of websites are responding to threats and block links in question. This company usually works for Bollywood studios but it also has among its clients Fox STAR Studios. DDoS attacks are usually illegal, they often rely on the use of computer networks Botnet slave type [2].

The 2010 Nobel Prize in Chemistry was awarded to researchers of Japanese nationality Akira Suzuki (Mukawir, Japan, 1930) and Ei-ichi Negishi (Changchun, China, 1935) and in Richard F. Heck (Springfield, USA, 1931), authors of three separate chemical reactions employing palladium catalysts to create carbon-carbon bonds by cross-matches.

As reported by the Royal Swedish Academy of Sciences in Stockholm, the three scientists were honored for having developed separately three different chemical reactions using palladium catalysts to join together atoms of carbon and synthesize complex molecules, that make life better human daily.

Palladium (Pd) is a chemical element located in group 10 of the periodic table of elements. Is a transition metal of the platinum group, soft, ductile, malleable, and very abundant. It resembles platinum chemically and is extracted from some copper and nickel mines. Used as a catalyst and in jewelry.

BBVA Foundation Awards for Biodiversity Conservation, raise additional environmental awards in the world have fallen this year in the Research Group Continental Margin Ecosystems (ECOMARG), the Spanish Institute of Oceanography, for his “decisive contribution” to creating the first Marine Protected Area ocean of Spain, known as the cap.

The Cachucho, officially named “Le Danois Bank ‘, after the French scientist who described it in 1948, is a clump of size equal to the Picos de Europa to emerge from the 4,500 meters deep in the Bay of Biscay, just 65 kilometers on the coast.

Since 2002, the group of international and multidisciplinary research ECOMARG study their characteristics. His studies have allowed to assess the ecological richness and conservation needs of this underwater mountain range, a unique ecosystem with high biodiversity and are studied and 50 species new to science.

How much water the body loses during exercise, either during a jog , a hike or a bike ride ? The body is he threatened by dehydration or a lack of minerals ? Researchers at the Fraunhofer Institute EMFT research and development for micro -therapy [1 ] Regensburg (Bavaria ) developed a T – shirt that shows the type and amount of sweating through color changes.

The first trials on T -shirt , covered with a layer of chemical agents , have proven inconclusive. By chemical reaction , the areas in contact with perspiration become jaunes.Le Dr. Gerhard Mohr ‘s Working Group ” sensorial materials “from the Fraunhofer EMFT explains that ” the color change is clearly visible and indicates that the athlete is time to rehydrate . This technology is based on the dyes used to determine the pH of rivers and wastewater .

A team of European astronomers has shown for the first time a very massive star has led to a magnetar, a neutron star, unusual , instead of a black hole as predicted by current theories. The finding raises the question of how massive a star must be to become a black hole.

European astronomers have demonstrated for the first time that a magnetar, a rare type of neutron star, formed from a star of at least 40 times the mass of the Sun The result challenges current theories of stellar evolution, because it was expected that such a massive star as it became a black hole , not a magnetar. This raises a fundamental question : how massive a star must be really to become a black hole?

To reach these conclusions , astronomers looked at in detail the remarkable star cluster Westerlund 1, located 16,000 light-years away in the southern constellation Ara (the Altar ). This super star cluster is the closest known , with hundreds of very massive stars inside -some shine with a glow similar to almost a million suns , and an area of some two hundred times the diameter of the Sun

The information obtained will be useful for conservation projects in this vertebrate Columbia River Basin

A group of zoologists at the University of British Columbia has discovered a new steroid hormone in the sea lamprey , a direct descendant of one of the first vertebrates appeared about 500 million years ago. The result sheds light on the evolution of steroid hormones and may help in the conservation efforts of those lampreys .

The hormone , called 11- deoxycortisol , is the body of the lamprey a role similar to that in humans is played by the aldosterone and cortisol helps regulate the balance of ions in cells and is involved in stress response .

” The origin of biochemical paths based on corticosteroids has remained controversial for decades because the identity of the ancestral corticosteroids has remained unknown so far , “said David Close , a professor in the department of zoology and director of UBC’s Fisheries Research Unit dell’Aboriginal UBC ‘s Fisheries Centre and co-author of ‘article published Online magazine Proceedings of the National Academy of Sciences. “This discovery will allow a better assessment of environmental factors that constitute a stress for species of lampreys .

If you smoke, your breath contains 2.5-Dimethylfuran. A team of Catalan researchers has shown that the presence of this chemical indicates that smoking in the past three days. This substance does not appear in the breath of nonsmokers, unless they have been in direct contact with smoke snuff for a long time.

“The 2.5-Dimethylfuran is not detectable in breath samples of non-smokers, so that only qualitative determination can tell if someone has smoked in the last 72 hours,” points out to SINC Juan Manuel Sanchez, a researcher Department of Chemistry, University of Girona (UdG) and coauthor of a study published in the journal Analytical and Bioanalytical Chemistry.

The UdG team analyzed various volatile organic compounds (benzene, 2,5-Dimethylfuran, toluene, o-xylene and p-xylene) that could serve as biomarkers of smoking status and found that 2.5-Dimethylfuran is alone gives effective results for breath samples.

“Benzene, which is sometimes mentioned in the literature, it is only useful when snuff consumption is relatively high and in short time-to-1 or 2 hours after consuming a cigarette, so it is useless from a practical, “says Sanchez.

For its part, the levels of toluene and xylenes are significant only for those who smoke heavily and provided there has been too long since the last cigarette.

The Spanish Committee of Automatic Control, headed by a professor at the Universidad Carlos III de Madrid, Miguel Angel Salichs, presented today in Zaragoza the White Paper on Automatic Control, in the presence of the Secretary of State for Research, Petriz Felipe Calvo.

The objective of Automatic Control White Paper is to review the current state of the theory and practice of automatic control in Spain, examining its relevance in the context of university education and industrial location. In addition, this volume examines the actions to be taken in the context of change that is the European Higher Education and technological advancement, to put this field at a level comparable to that of our European environment.

Automatic control is the branch of engineering devoted to the systems operate independently, allowing to carry out, among others, tasks that a human operator is not capable of doing. “Despite its ubiquity in technical systems, often do not explicitly mention it, so that he comes to call hidden technology,” said Miguel Angel Salichs.

Getting a good is monitored at all times, from the origin until it reaches the destination safely and in real time. This is what I have got a group of researchers from the Public University of Navarra and the Navarra TB-Solutions company specializing in developing secure communications platforms. His work is included in the proposed Intermodal Freight Intelligent Transport (TIMI) and work in the commercial development of its product.

The project’s objective is to develop TIMI new technologies to create a future generation of devices, systems and tools to make more intelligent intermodal transport (land, sea, rail and air). To do this, under a project CENIT, in the year 2007, a consortium of ten companies, in collaboration with universities and public institutions, have worked on different aspects of the project. The Navarre TB-Solutions UPNA resorted to for its researchers developed the necessary software and collaboration has borne fruit.

By the University, Jose Javier Astrain, Jesus Villadangos, Aritz Labat, Alberto Cordoba, Marcos and Carlos Goyeneche Aristu have been responsible for the project. Have achieved the necessary hardware and software have been installed in sensors, devices located in each container is responsible for wireless transmitting information.

After two weeks of work, today it has completed the Fourteenth Meeting of the Scientific Advisory Committee of the Convention on Biological Diversity in Nairobi (Kenya) where contributions of experts from the Ministry of Environment, Rural and Marine Affairs (MARM). The proposals include identifying ecologically valuable marine areas, promote sustainable consumption, encourage conservation, and setting measurable targets and realistic after 2010.

During the meeting, the scientific advisory committee has proposed overhaul of the current work program of coastal and marine biodiversity with a view to their reintegration, and especially pay attention to the identification of areas of special ecological interest, the assessment of impacts and risks of unsustainable activities on marine biodiversity, and adverse effects of climate change.

Over 500 international experts present at the meeting held in Kenya have established the need to devise voluntary and market instruments (such as certification, green purchasing, or management of the supply chain) to promote production and consumption models based on the sustainable use of biodiversity.
