New device could turn heat energy into a viable fuel source
A new device being developed by Washington State University physicist Yi Gu could one day turn the heat generated by a wide array of electronics into a usable fuel source. The device is a multicomponent, multilayered composite material called a van der Waals Schottky diode. It converts heat into electricity up to three times more efficiently than silicon -- a semiconductor material widely used in the electronics industry.

Jordan faces likelihood of much more frequent long and severe droughts
Jordan is among the world's most water-poor nations, and a new, comprehensive analysis of regional drought and land-use changes in upstream Syria suggests the conditions could get significantly worse.

Key factor identified in gene silencing
In a paper published this week in Proceedings of the National Academy of Sciences, Hengbin Wang and colleagues describe a key role for a protein called RSF1 in silencing genes. Besides the molecular biology details, the researchers also showed that disruption of RSF1 expression in the embryos of African clawed frogs caused severe developmental defects in the tadpoles -- through a dysregulation of mesodermal cell fate specification.

Periodic table of ecological niches could aid in predicting effects of climate change
A group of ecologists has started creating a periodic table of ecological niches similar to chemistry's periodic table. It will be a critical resource for scientists seeking to understand how a warming climate may be spurring changes in species around the globe.

Scientists discover spring-loaded mechanism in unusual species of trap-jaw ant
Researchers provide the first mechanical description of the jaws of a group of trap-jaw ants that can snap their spring-loaded jaws shut at speeds of up to 50 miles per hour -- just fast enough to capture their elusive prey. (Includes video.)

Patient plays saxophone while surgeons remove brain tumor
Music is not only a major part of Dan Fabbio's life, as a music teacher it is his livelihood. So when doctors discovered a tumor located in the part of his brain responsible for music function, he began a long journey that involved a team of physicians, scientists, and a music professor and culminated with him awake and playing a saxophone as surgeons operated on his brain.

Acting like a muscle, nano-sized device lifts 165 times its own weight
New Brunswick engineers have discovered a simple, economical way to make a nano-sized device that can match the friendly neighborhood Avenger, on a much smaller scale. Their creation weighs 1.6 milligrams (about as much as five poppy seeds) and can lift 265 milligrams (the weight of about 825 poppy seeds) hundreds of times in a row.

Volcanic eruptions drove ancient global warming event
A natural global warming event that took place 56 million years ago was triggered almost entirely by volcanic eruptions that occurred as Greenland separated from Europe during the opening of the North Atlantic Ocean, according to an international team of researchers that includes Andy Ridgwell, a University of California, Riverside professor of earth sciences.

Study finds pallid bat is unfazed by venom of Arizona bark scorpion
The Arizona bark scorpion is the most venomous scorpion in North America. The pallid bat is believed to be resistant to scorpion venom, but no laboratory studies have been performed to confirm this. Researchers at the University of California, Riverside now report in PLOS ONE that the pallid bat hunts the Arizona bark scorpion but is unaffected by its venom even after it is stung multiple times during the hunt.

Scientists reveal how these ants snap their jaws shut in the blink of an eye
Few victims stand a chance against the formidable mandibles of a trap-jaw ant. In conflicts between predators and prey, speed is a decided advantage, and evolution has given these insects an edge with spring-loaded jaws that snap shut with astonishing speed. In the Aug. 30 issue of the Journal of Experimental Biology, scientists at the Smithsonian's Natural History Museum provide the first mechanical description of the jaws of a little-known group of trap-jaw ants.

Bahamian songbirds disappeared during last glacial-interglacial transition
Two species of songbirds that once made a home in the Bahamas likely became extinct on the islands because of rising sea levels and a warmer, wetter climate, according to a new study by researchers at the University of California, Riverside and the University of Florida, Gainesville. The study, which was published today in the Proceedings of the National Academy of Sciences, presents a historical view of how climate change and the resulting habitat loss can affect Earth's biodiversity.

Tears in tiny bone cells called osteocytes appear an important step to better bones
The force gravity and physical activity put on our bones causes tiny tears in the membranes of the tiny cells that enable us to make or break down bone, scientists say. While that may sound bad, it's actually a key piece of how the force we put on our bones helps keep them strong, they report in the Journal of Orthopaedic Research.

Inattentive kids show worse grades in later life
Researchers found that inattentiveness in childhood was linked to worse academic performance up to 10 years later in children with and without ADHD, even when they accounted for the children's intellectual ability. The results highlight the long-term effects that childhood inattention can have on academic performance, and suggest that parents and teachers should address inattentiveness in childhood.
