 Monthly Notices of the Royal Astronomical SocietyCSI: Milky Way There is growing evidence that several million years ago the center of the Milky Way galaxy was site of all manner of celestial fireworks and a pair of astronomers from Vanderbilt and Georgia Institute of Technology propose that a single event -- a black hole collision -- can explain all the "forensic" clues.

Nature GeoscienceThe making of Antarctica's hidden fjords Antarctica's topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists. Knowing when Antarctica's topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise.

Physical Review LettersStressed proteins can cause blood clots for hours New research from Rice University, Baylor College of Medicine and the Puget Sound Blood Center has revealed how stresses of flow in the small blood vessels of the heart and brain could cause a common protein to change shape and form dangerous blood clots. The scientists report this week in Physical Review Letters that the proteins can remain in the clot-initiating shape for up to five hours before settling back into their normal, healthy shape.

Astrophysical JournalNew evidence that comets could have seeded life on Earth UC Berkeley and Univ. of Hawaii scientists have shown that complex molecules can form on icy dust in space, suggesting that comets may have brought these molecules to Earth and seeded the growth of more complex building blocks of life. The team zapped icy snowballs of carbon dioxide and hydrocarbons, producing complex molecules, such as dipeptides, that are capable of catalyzing the formation of more complex structures.

GeneticsDoes the villainous 'selfish' gene undermine genome's police? Biologists have been observing the "selfish" genetic entity segregation distorter (SD) in fruit flies for decades. Its story is a thriller among molecules, in which the SD gene destroys maturing sperm that have a rival chromosome. A new study reveals a tactic that gives SD's villainy an extra edge.

Proceedings of the Royal Society BStressed-out tadpoles grow larger tails to escape predators When people or animals are thrust into threatening situations such as combat or attack by a predator, stress hormones are released to help prepare the organism to defend itself or to rapidly escape from danger -- the so-called fight-or-flight response.

Nature Communications'True grit' erodes assumptions about evolution New work in Argentina where scientists had previously thought Earth's first grasslands emerged 38 million years ago, shows the area at the time covered with tropical forests rich with palms, bamboos and gingers. Grit and volcanic ash in those forests could have caused the evolution of teeth in horse-like animals that scientists mistakenly thought were adaptations in response to emerging grasslands.

Proceedings of the National Academy of SciencesNew research confirms plight of bumble bees, persistence of other bees in Northeast A new study shows that although certain bumble bees are at risk, other bee species in the northeastern United States persisted across a 140-year period despite expanding human populations and changing land use. Led by Rutgers University and based extensively on historical specimens from the American Museum of Natural History and nine other bee collections, the study informs conservation efforts aimed at protecting native bee species and the important pollinator services they provide.

Nature PhysicsVortex loops could untie knotty physics problems University of Chicago physicists have succeeded in creating a vortex knot -- a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, but creating them in the laboratory had previously eluded scientists.

Scientists call for greater access to biodiversity resources, data The American Institute of Biological Sciences has released a report from a workshop of experts that was convened last fall to outline the steps needed to build a Network Integrated Biocollections Alliance (NIBA) in the next ten years. NIBA is a national scientific, engineering, and data management initiative first called for in 2010. When built, NIBA will provide online access to digitized data for biological specimens.

Nature PhysicsImproved synchronicity: Preventive care for the power grid As the national power-grid network becomes larger and more complex, achieving reliability across the network is increasingly difficult. Now Northwestern University scientists have identified conditions and properties that power companies can consider using to keep power generators in the desired synchronized state. The design could help reduce both the frequency of blackouts and the cost of electricity as well as offer an improved plan for handling the intermittent power sources of renewable energy, which can destabilize the network.

Personality and Social Psychology BulletinLiving through a tornado does not shake optimism Even in the face of a disaster, we remain optimistic about our chances of injury compared to others, according to a new study. Residents of a town struck by a tornado thought their risk of injury from a future tornado was lower than that of peers, both a month and a year after the destructive twister. Such optimism could undermine efforts toward emergency preparedness.

Earth and Planetary Science LettersMineral diversity clue to early Earth chemistry Mineral evolution is a new way to look at our planet's history. It's the study of the increasing diversity and characteristics of Earth's near-surface minerals, from the dozen that arrived on interstellar dust particles when the Solar System was formed to the more than 4,700 types existing today. New research on a mineral called molybdenite provides important new insights about the changing chemistry of our planet as a result of geological and biological processes.
