First detailed picture of cancer-related cell enzyme in action on chromosome unit
New insight into the function of an enzyme related to the BRCA1 breast-cancer protein has been released by researchers. The study produced the first detailed working image of an enzyme in a group that is associated with many types of cancer. The researchers obtained the first crystal structure of a gene-regulation enzyme working on a nucleosome. The image reveals previously unknown information about how the enzyme attaches to its nucleosome target.

Running robots of future may learn from world's best two-legged runners: Birds
With an eye toward making better running robots, researchers have made surprising new findings about some of nature's most energy efficient bipeds -- running birds. Their skills may have evolved from the time of the dinosaurs and they may now be superior to any other bipedal runners -- including humans.

The science of charismatic voices: How one man was viewed as authoritarian, then benevolent
When a right-wing Italian politician named Umberto Bossi suffered a severe stroke in 2004, his speech became permanently impaired. Strangely, this change impacted Bossi’s perception among his party’s followers -- from appearing authoritarian to benevolent. Now researchers think they know why.

Urban seismic network detects human sounds
When listening to the Earth, what clues can seismic data reveal about the impact of urban life? Although naturally occurring vibrations have proven useful to seismologists, until now the vibrations caused by humans haven’t been explored in any real depth. Researchers have described their efforts to tap into an urban seismic network to monitor the traffic of trains, planes, automobiles and other modes of human transport.

Plump turtles swim better: First models of swimming animals
Bigger is better, if you're a leatherback sea turtle. For the first time, researchers have measured the forces that act on a swimming animal and the energy the animal must expend to move through the water.

Innovative study utilizing video games shows sleep apnea may affect memory of everyday events
Sleep apnea may affect your ability to form new spatial memories, such as remembering where you parked your car, new research suggests. The study demonstrates through the playing of a specific video game that disruption of rapid eye movement (REM) sleep as a consequence of sleep apnea impairs spatial memory in humans even when other sleep stages are intact.

Low carb, high fat diets may reduce seizures in tough-to-treat epilepsy
Diets high in fat and low in carbohydrates, such as the ketogenic or modified Atkins diet, may reduce seizures in adults with tough-to-treat epilepsy, according to a review of research.

Novel ultrasound technology to screen for heart conditions developed by engineers
Engineers have determined, for the first time, the impact of a ring-shaped vortex on transporting blood flow in normal and abnormal ventricles within the human heart, and have developed a novel ultrasound technology that makes screening cheaper and much easier, making it possible to reach a large number of people and even infants.

Ammonium source in open ocean tracked by researchers
To understand the extent to which human activities are polluting Earth's atmosphere and oceans, it's important to distinguish human-made pollutants from compounds that occur naturally. A new study finds that deposition of ammonium, a source of nitrogen pollution, over the open ocean comes mostly from natural marine sources, and not from human activity.
