For decades, neuroscientists have been trying to design computer networks that can mimic visual skills such as recognizing objects. Until now, no computer model has been able to match the primate brain at visual object recognition during a brief glance. However, a new study from MIT neuroscientists has found that one of the latest generation of these so-called “deep neural networks” matches the primate brain.

Researchers have detected at least three instances of cross-species mating that likely influenced the evolutionary paths of “old world” mice, two in recent times and one in the distant past. They think these instances of introgressive hybridization are only the first of many needles waiting to be found in a very large genetic haystack. The finding suggests that hybridization in mammals may not be an evolutionary dead end.
NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory’s drill. Researchers used Curiosity’s onboard Sample Analysis at Mars laboratory a dozen times in a 20-month period to sniff methane in the atmosphere. During two of those months, four measurements averaged seven ppb.
IBM announced that the U.S. Department of Veterans Affairs is using Watson technology in a pilot to assist physicians in helping accelerate the process of evidence-based medical decision making. The VA joins leading healthcare organizations that are working with IBM Watson to help improve efficiency and quality of care being delivered. The VHA will also work with Watson for a clinical focus supporting veterans with PTSD.
Using a computer algorithm that can sift through mounds of genetic data, researchers from Brown University have identified several networks of genes that, when hit by a mutation, could play a role in the development of multiple types of cancer. The algorithm, called Hotnet2, was used to analyze genetic data from 12 different types of cancer assembled as part of the pan-cancer project of The Cancer Genome Atlas (TCGA).
About 95 percent of the more than 10,000 bird species known only evolved upon the extinction of dinosaurs about 66 million years ago. According to computer analyses of the genetic data, today's diversity developed from a few species at a virtually explosive rate after 15 million years. Scientists designed the algorithms for the comprehensive analysis of the evolution of birds; a computing capacity of 300 processor-years was required.
Although there are a diverse range of applications for predictive analytics in R&D, two common basic requirements are data and insight. Data may be generated by running experiments/analyses, or re-applied from previous work when available. Insights come from application of knowledge — both explicitand tacit. There are a variety of roles for informatics in predictive analytics...
The genomes of modern birds tell a story of how they emerged and evolved after the mass extinction that wiped out dinosaurs and almost everything else 66 million years ago. That story is now coming to light, thanks to an ambitious international collaboration that has been underway for four years. The first findings of the Avian Phylogenomics Consortium are being reported nearly simultaneously in 28 papers.
Where did the songbird get its song? What branch of the bird family tree is closer to the flamingo — the heron or the sparrow? These questions seem simple, but are actually difficult for geneticists to answer. A new, sophisticated statistical technique can help researchers construct more accurate species trees detailing the lineage of genes and the relationships between species.
The mystery of where Earth's water came from got murkier on December 10, 2014, when some astronomers essentially eliminated one of the chief suspects: comets. Over the past few months, the European Space Agency's Rosetta space probe closely examined the type of comet that some scientists theorized could have brought water to our planet 4 billion years ago. It found water, but the wrong kind.
MS affects more than two million people worldwide. Symptoms are different for everyone but commonly include fatigue, tingling, speech problems and difficulties with walking and balance. To gain a better understanding of MS and its treatments, there is a need for a system to collect comprehensive data that provides an in-depth picture of the experiences of MS patients across a large population.
Intel demonstrated for the first time with Professor Stephen Hawking a new Intel-created communications platform to replace his decades-old system, dramatically improving his ability to communicate with the world. The customizable platform will be available to research and technology communities by January of next year. It has the potential to become the backbone of a modern, customizable system other researchers and technologists can use.
Scientists at Scripps Research Institute have teamed with IBM on a project that aims to combine the power of thousands of small computers to help analyze various compounds to see which might be effective in attacking the Ebola virus and also to help with a longer-term effort to understand how Ebola proteins change shape over time.
Russia's richest man says he has bought James D. Watson's Nobel Prize medal at Christie's in order to return it to the scientist. The 1962 Nobel Prize in Physiology or Medicine was awarded jointly to Francis Harry Compton Crick, James Dewey Watson and Maurice Hugh Frederick Wilkins "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material."
Tracing the evolution of Charles Darwin’s thoughts about evolution is becoming an increasingly accessible project, thanks to a growing cache of publicly available digitized Darwin manuscripts on the American Museum of Natural History’s Web site. By June 2015, the Museum will host more than 30,000 digitized documents written by Darwin between 1835 and 1882.

Geckos have fascinated people for hundreds of years. Scientists have been especially intrigued by these lizards, and have studied a variety of features such as the adhesive toe pads on the underside of gecko feet with which geckos attach to surfaces with remarkable strength. One question that has captivated researchers is: Is the strength of this adhesion determined by the gecko or is it somehow intrinsic to the adhesive system?
Biological engineers have created a new computer model that allows them to design the most complex three-dimensional DNA shapes ever produced, including rings, bowls, and geometric structures such as icosahedrons that resemble viral particles.
In 1997, IBM’s Deep Blue computer beat chess wizard Garry Kasparov.

Researchers have made great progress in recent years in the design and creation of biological circuits — systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But, while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined.
Van der Waals forces act like a sort of quantum glue on all types of matter. Using a new measuring technique, scientists from Forschungszentrum Jülich experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface. With an atomic force microscope, they demonstrated that the forces do not just increase with molecular size, but that they even grow disproportionately fast.
