Study details impact of Deepwater Horizon oil on beach microbial communities
Using advanced genomic identification techniques, researchers studying the impact of the Deepwater Horizon spill on communities of beach microbes saw a succession of organisms and identified population changes in specific organisms that marked the progress of the oil's breakdown.

A close call of 0.8 light years
A group of astronomers from the US, Europe, Chile and South Africa have determined that 70,000 years ago a recently discovered dim star is likely to have passed through the solar system's distant cloud of comets, the Oort Cloud. No other star is known to have ever approached our solar system this close - five times closer than the current closest star, Proxima Centauri.

Tadpole model links drug exposure to autism-like effects
In utero exposure to the epilepsy drug VPA appears to elevate the risk to babies of developing an autism spectrum disorder. A new Brown University study used a tadpole model to investigate VPA's effects on developing neural physiology and behavior. Researchers now hope to use the model to develop an intervention and to learn more about the underlying causes of neurodevelopmental disorders more broadly.

Researchers synthesize material for efficient plasmonic devices in mid-infrared range
A research team led by North Carolina State University has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared range. This is the first time anyone has demonstrated a material that performs efficiently in response to this light range, and it has applications in fields ranging from high-speed computers, to solar energy to biomedical devices.

Distant species produce love child after 60 million year breakup
A delicate woodland fern discovered in the mountains of France is the love child of two distantly-related groups of plants that haven't interbred in 60 million years, genetic analyses show. Reproducing after such a long evolutionary breakup is akin to an elephant hybridizing with a manatee, or a human with a lemur, the researchers say.

Larger area analysis needed to understand patterns in ancient prehistory
Archaeologists need to study larger areas of land and link those studies to measurable environmental, societal and demographic changes to understand variations in prehistoric societies, according to Penn State anthropologists. The large areas are necessary to say anything meaningful about human behavioral response to social and environmental events.

Researchers glimpse distortions in atomic structure of materials

Under pressure
Just as human relationships are a two-way street, fusion between cells requires two active partners: one to send protrusions into its neighbor, and one to hold its ground and help complete the process. Researchers have found that one way the receiving cell plays its role is by having a key structural protein come running in response to pressure on the cell membrane, rather than waiting for chemical signals to tell it that it's needed.

Carnegie Mellon researchers reveal how mindfulness training affects health
Over the past decade, there have been many encouraging findings suggesting that mindfulness training can improve a broad range of mental and physical health problems. Yet, exactly how mindfulness positively impacts health is not clear. Carnegie Mellon University researchers have developed a model suggesting that mindfulness influences health via stress reduction pathways.

Rutgers-led team makes stride in explaining 30-year-old 'hidden order' physics mystery
A new explanation for a type of order, or symmetry, in an exotic material made with uranium is a major step toward explaining a puzzle that physicists worldwide have been struggling with for 30 years. This 'hidden order' appears as a subtle change in the material's electrical and magnetic properties when the material is cooled to 17.5 degrees above absolute zero or lower -- a bone-chilling minus 428 degrees Fahrenheit.

Making teeth tough: Beavers show way to improve our enamel
Beavers don't brush their teeth or drink fluoridated water, but a new Northwestern University study reports beavers do have protection against tooth decay built into the chemical structure of their teeth: iron. This pigmented enamel, the researchers found, is both harder and more resistant to acid than regular enamel, including that treated with fluoride. This discovery is among others that could lead to a better understanding of human tooth decay, earlier detection of the disease and improving on current fluoride treatments.

A new species of hummingbird?
The Bahama Woodstar is a hummingbird found in the Bahamas, and comprises two subspecies. One of these is found throughout the islands of the Bahamas, and especially in the northern islands. The other is found only among the southern Inaguan islands of the Bahama Archipelago. A research team that includes biologist Christopher J. Clark at the University of California, Riverside now argues that the two subspecies should be recognized as two distinct species.

A gene that shaped the evolution of Darwin's finches
Researchers from Princeton University and Uppsala University in Sweden have identified a gene in Galápagos finches studied by English naturalist Charles Darwin that influences beak shape and that played a role in the birds' evolution from a common ancestor. The study illustrates the genetic foundation of evolution, including how genes can flow from one species to another, and how different versions of a gene within a species can contribute to the formation of new species.

Monster hurricanes reached US Northeast during prehistoric periods of ocean warming
Intense hurricanes possibly more powerful than any storms New England has experienced in recorded history frequently pounded the region during the first millennium, from the peak of the Roman Empire into the height of the Middle Ages, according to a new study. The findings could have implications for the intensity and frequency of hurricanes that the US East and Gulf coasts could experience as ocean temperatures increase as a result of climate change.

Apes prefer the glass half full
Humans aren't the only species to be influenced by spin. Our closest primate relatives are susceptible, too. For example, people rate a burger as more tasty when it is described as '75 percent lean' than when it is described as '25 percent fat,' even though that's the same thing. A Duke University study finds that positive and negative framing make a big difference for chimpanzees and bonobos too.
