Artifacts in Texas predate Clovis culture by 2,500 years, new study shows (March 25, 2011) -- Researchers in Texas have discovered thousands of human artifacts in a layer of earth that lies directly beneath an assemblage of Clovis relics, expanding evidence that other cultures preceded the Clovis culture in North America. ... > full story

Unexpected action of bisphenol A on the inner ear of certain vertebrates (March 25, 2011) -- Bisphenol A, whose impact on reproduction and development is the subject of numerous studies, induces anomalies in the inner ear of embryos of certain vertebrates. This new, completely unsuspected effect has been demonstrated on zebrafish and Xenopus, a type of frog. These results illustrate, for the first time, the sensitivity of the inner ear in vertebrates to bisphenol A. The study demonstrates that the effects of this chemical compound on the embryonic development of animals, including mammals, now needs to be explored in greater depth. ... > full story

Universal property of music discovered (March 25, 2011) -- Researchers have discovered a universal property of scales. Until now it was assumed that the only thing scales throughout the world have in common is the octave. The many hundreds of scales, however, seem to possess a deeper commonality: if their tones are compared in a two- or three-dimensional way by means of a coordinate system, they form convex or star-convex structures. Convex structures are patterns without indentations or holes, such as a circle, square or oval. ... > full story

BrainGate neural interface system reaches 1,000-day performance milestone (March 25, 2011) -- An investigational implanted system being developed to translate brain signals toward control of assistive devices has allowed a woman with paralysis to accurately control a computer cursor at 2.7 years after implantation, providing a key demonstration that neural activity can be read out and converted into action for an unprecedented length of time. ... > full story

Exploding stars and stripes: Pattern of X-ray 'stripes' in supernova remnant could explain how cosmic rays are produced (March 25, 2011) -- The discovery of a pattern of X-ray "stripes" in the remains of an exploded star may provide the first direct evidence that a cosmic event can accelerate particles to energies a hundred times higher than achieved by the most powerful particle accelerator on Earth. This result comes from a very long observation of the Tycho supernova remnant with NASA's Chandra X-ray Observatory. It could explain how some of the extremely energetic particles bombarding Earth, called cosmic rays, are produced. ... > full story

First student-developed mission in which satellites orbit and communicate (March 25, 2011) -- Two satellites designed and constructed by engineering students in Texas successfully separated in space March 22, completing the most crucial goal of the mission since its Nov. 19 launch and making them the first student-developed mission in the world in which satellites orbit and communicate with each other in real-time. ... > full story

Matter spotted a millisecond from black hole -- but is it really doomed? (March 25, 2011) -- The European Space Agency's Integral gamma-ray observatory has spotted extremely hot matter just a millisecond before it plunges into the oblivion of a black hole. But is it really doomed? These unique observations suggest that some of the matter may be making a great escape. ... > full story

High-temperature superconductor spills secret: A new phase of matter? (March 25, 2011) -- Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter. Understanding this "pseudogap" has been a 20-year quest for researchers who are trying to control and improve these breakthrough materials, with the ultimate goal of finding superconductors that operate at room temperature. ... > full story

Suzaku shows clearest picture yet of Perseus Galaxy Cluster (March 24, 2011) -- X-ray observations made by the Suzaku observatory provide the clearest picture to date of the size, mass and chemical content of a nearby cluster of galaxies. The study also provides the first direct evidence that million-degree gas clouds are tightly gathered in the cluster's outskirts. ... > full story
