Mapping the "Big Bang" of Bird Evolution

December 12, 2014 6:04 pm | by Kelly Rae Chi, Duke University | News | Comments

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.

Sophisticated New Statistical Technique helps Map Species' Genetic Heritage

December 12, 2014 5:50 pm | by Liz Ahlberg, University of Illinois | News | Comments

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.

EPFL scientists have picked up an atypical photon emission in X-rays coming from space, and say it could be evidence for the existence of a particle of dark matter.

Atypical Photon Emission a Possible Signal from Dark Matter

December 12, 2014 5:40 pm | by Ecole Polytechnique Fédérale de Lausanne | News | Comments

Could there finally be tangible evidence for the existence of dark matter in the Universe? After sifting through reams of X-ray data, scientists at EPFL and Leiden University believe they could have identified the signal of a particle of dark matter. This substance, which up to now has been purely hypothetical, is run by none of the standard models of physics other than through the gravitational force.

New Theory could Yield More Reliable Communication Protocols

December 12, 2014 5:23 pm | by Larry Hardesty, MIT | News | Comments

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.

Mystery Deepens: Where Did Earth's Water Come From?

December 11, 2014 4:32 pm | by Seth Borenstein, AP Science Writer | News | Comments

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.

Solving the Shaky Future of Super-strong Rare Earth Magnets

December 11, 2014 4:15 pm | by Katie Elyce Jones, Oak Ridge National Laboratory | News | Comments

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.

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.
