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.
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.
Monstrous moonshine, a quirky pattern of the monster group in theoretical math, has a shadow — umbral moonshine. Mathematicians have proved this insight, known as the Umbral Moonshine Conjecture, offering a formula with potential applications for everything from number theory to geometry to quantum physics.
Just in time for Christmas, Richard Zhang reveals how to print a 3-D Christmas tree efficiently and with zero material waste, using the world’s first algorithm for automatically decomposing a 3-D object into what are called pyramidal parts. The algorithm promises to become a big deal in the world of 3-D printing, and also has applications for designing molds and for casting.
NASA researchers began flight tests of computer software that shows promise in improving flight efficiency and reducing environmental impacts of aircraft, especially on communities around airports. Known as ASTAR, or Airborne Spacing for Terminal Arrival Routes, the software is designed to give pilots specific speed information and guidance so that planes can be more precisely spaced, enabling pilots to fly a "follow the leader" approach.
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...
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.
Communication protocols for digital devices are very efficient but also very brittle: They require information to be specified in a precise order with a precise number of bits. If sender and receiver — say, a computer and a printer — are off by even a single bit relative to each other, communication between them breaks down entirely.
The US Department of Energy is mining for solutions to the rare earth problem — but with high-performance computing instead of bulldozers. Researchers are using the hybrid CPU-GPU, 27-petaflop Titan supercomputer managed by the Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory to discover alternative materials that can substitute for rare earths.
What does a black hole look like up close? As the sci-fi movie Interstellar wows audiences with its computer-generated views of one of most enigmatic and fascinating phenomena in the universe, University of Arizona (UA) astrophysicists Chi-kwan Chan, Dimitrios Psaltis and Feryal Ozel are likely nodding appreciatively and saying something like, "Meh, that looks nice, but check out what we've got."
An interstellar mystery of why stars form has been solved thanks to the most realistic supercomputer simulations of galaxies yet made. Theoretical astrophysicist Philip Hopkins led research that found that stellar activity — like supernova explosions or even just starlight — plays a big part in the formation of other stars and the growth of galaxies.
World's Oldest Computer, Ancient Greek Antikythera Mechanism, 100 Years Older than Previously BelievedDecember 9, 2014 2:10 pm | by University of Puget Sound | News | Comments
An ancient Greek astronomical puzzle has one more piece in place. The new evidence results from research by James Evans, professor of physics at University of Puget Sound, and Christián Carman, history of science professor at University of Quilmes, Argentina. The two researchers published a paper advancing our understanding of the Antikythera Mechanism, an ancient Greek mechanism that modeled the known universe of 2,000 years ago.
Engineers have designed and built a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead to computers that use optics, rather than electricity, to carry data. The optical link is a tiny slice of silicon etched with a pattern that resembles a bar code. When a beam of light is shined at the link, two different wavelengths of light split off
Scientists have developed an ultrafast quantum chemical method, which allows rapid and accurate simulations of complex molecular systems consisting of thousands of molecules.
An international competition using the wisdom of crowds has developed computer algorithms to detect, predict, and ultimately prevent epileptic seizures. A total of five-hundred and four teams competed in two challenges, one for Seizure Detection and a second for Seizure Prediction.
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. This year, a computer system developed at the University of Wisconsin-Madison equaled or bested scientists at the complex task of extracting data from scientific publications and placing it in a database that catalogs the results of tens of thousands of individual studies.
El Niño is not a contemporary phenomenon; it’s long been the Earth’s dominant source of year-to-year climate fluctuation. But as the climate warms and the feedbacks that drive the cycle change, researchers want to know how El Niño will respond.
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.
