Changes in primate teeth linked to rise of monkeys
UC Berkeley's Leslea Hlusko searches for simple inherited dental characteristics that could lead to genes controlling tooth development, and has ucovered an easy-to-measure trait that tracks primate evolution over the last 20 million years, shedding light on the mysterious decline of apes and the rise of monkeys 8 million years ago. She concludes that monkeys diversified and took over the dentition niche of the majority of apes. Apes with outlying dentition, including human ancestors, remained.

Ultrashort cell-free DNA reveals health of organ transplants
When cells die, whether through apoptosis or necrosis, the DNA and other molecules found in those cells don't just disappear. They wind up in the blood stream, where degraded bits and pieces can be extracted.

A 'time switch' in the brain improves sense of smell 
When the brain processes olfactory stimuli, it differentiates between similar smells using subtly modulated signals. Brain examinations and behavioral studies in mice have now shown that neurons with inhibiting characteristics play a key role in this process.

University of Illinois researchers demonstrate tunable wetting and adhesion of graphene
Researchers from the University of Illinois at Urbana-Champaign have demonstrated doping-induced tunable wetting and adhesion of graphene, revealing new and unique opportunities for advanced coating materials and transducers. The study suggests for the first time that the doping-induced modulation of the charge carrier density in graphene influences its wettability and adhesion.

New clues could help scientists harness the power of photosynthesis
A discovery has been made that could enable scientists to design better ways to use light energy and to engineer crop plants that more efficiently harness the energy of the Sun. The identification of a gene needed to expand light harvesting in photosynthesis into the far-red-light spectrum provides clues to the evolution of oxygen-producing photosynthesis, an evolutionary advance that changed the history of life on Earth.

Newly discovered planet has 3 suns
A team of astronomers led by the University of Arizona has discovered a planet in a unique position between three stars. The finding shows that massive planets may be found on long and possibly unstable orbits in multi-star systems, expanding current models of how star systems and their planets form.

Robot helps study how first land animals moved 360 million years ago
When early terrestrial animals began moving about on mud and sand 360 million years ago, the powerful tails they used as fish may have been more important than scientists previously realized. That's one conclusion from a new study of African mudskipper fish and a robot modeled on the animal.

A sharper focus for plasmonic lasers
Lehigh University researcher Sushil Kumar and his group have demonstrated that it is possible to induce plasmonic lasers to emit a narrow beam of light by adapting a technique called distributed feedback. They have experimentally implemented a scheme for terahertz plasmonic lasers that emit radiation at extremely long wavelengths (approximately 100 microns). Their results have been published today in an article in Optica, the journal of the Optical Society of America.

Bees' ability to forage decreases as air pollution increases
Air pollutants interact with and break down plant-emitted scent molecules, which insect pollinators use to locate needed food, according to a team of researchers led by Penn State. The pollution-modified plant odors can confuse bees and, as a result, bees' foraging time increases and pollination efficiency decreases. This happens because the chemical interactions decrease both the scent molecules' life spans and the distances they travel.

'Omics' data improves breast cancer survival prediction
Precise predictions of whether a tumor is likely to spread would help clinicians and patients choose the best course of treatment. But current methods fall short of the precision needed. New research reveals that profiling primary tumor samples using genomic technologies can improve the accuracy of breast cancer survival predictions compared to clinical information alone. The study was published in the journal GENETICS, a publication of the Genetics Society of America.

Eye of the beetle: How the Emerald Ash Borer sees may be key to stopping it
This iridescent jewel beetle, responsible for the death of more than 50 million ash trees in the United States, has blazed an absolute path of destruction west since its discovery in Michigan in 2002. Recently the pest has been detected in Colorado, and just this spring it was confirmed in Nebraska and Texas. Researchers at BYU have been doing more than just watching the migration patterns--they've been studying the creature in hopes of helping to slow it.

Learning about the hummingbirds and the bees in floral diversity
The floral diversity and repeated shifts in pollination have inspired a series of scientists to study adaptive evolution in the genus. But until now many of the species relationships have been unresolved and hampered by the very thing that makes studying the genus so appealing. The rapid speciation and evolutionary radiation that makes studying adaptation in these groups so interesting have also meant the species relationships have been difficult to resolve -- until now.

Study: How we explain things influences what we think is right
New research focuses on a fundamental human habit: When trying to explain something (why people give roses for Valentine's Day, for example), we often focus on the traits of the thing itself (roses are pretty) and not its context (advertisers promote roses). In a new study, researchers found that people who tend to focus on 'inherent traits' and ignore context also are more likely to assume that the patterns they see around them are good.
