COLUMBUS, Ohio — In a discovery that raises further concerns about the future contribution of Antarctica to sea level rise, a new study finds that the western part of the ice sheet is experiencing nearly twice as much warming as previously thought.
The temperature record from Byrd Station, a scientific outpost in the center of the West Antarctic Ice Sheet (WAIS), demonstrates a marked increase of 4.3 degrees Fahrenheit (2.4 degrees Celsius) in average annual temperature since 1958—that is, three times faster than the average temperature rise around the globe.

Mild cooling of the brain after a head injury prevents the later development of epileptic seizures, according to an animal study reported this month in the Annals of Neurology.
Epilepsy can result from genetics or brain damage. Traumatic head injury is the leading cause of acquired epilepsy in young adults. It is often difficult to manage with antiepileptic drugs. The mechanisms behind the onset of epileptic seizures after brain injury are not known . There is currently no treatment to cure it, prevent it, or even limit its severity. (more…)
Two groups — clades — of grasses that once had a common ancestry diverged. The PACMAD clade was predisposed to evolve a more efficient “C4” means of photosynthesis than grasses in the BEP clade. In a new study in the Proceedings of the National Academy of Sciences, a Brown-led team pinpoints the anatomical differences between the clades that led to the PACMAD’s tendency toward C4.
PROVIDENCE, R.I. [Brown University] — Even on the evolutionary time scale of tens of millions of years there is such a thing as being in the right shape at the right time. An anatomical difference in the ability to seize the moment, according to a study led by Brown University biologists, explains why more species in one broad group, or clade, of grasses evolved a more efficient means of photosynthesis than species in another clade.

COLUMBUS, Ohio – A new study of the batteries commonly used in hybrid and electric-only cars has revealed an unexpected factor that could limit the performance of batteries currently on the road.
Researchers led by Ohio State University engineers examined used car batteries and discovered that over time lithium accumulates beyond the battery electrodes – in the “current collector,” a sheet of copper which facilitates electron transfer between the electrodes and the car’s electrical system.

People who worry constantly are at greater risk for post-traumatic stress disorder, according to new Michigan State University research published in the journal Psychological Medicine.
Many people experience traumatic events such as the death of a loved one, being assaulted or witnessing violence, but only a small minority develop PTSD, said study author Naomi Breslau, a professor of epidemiology at MSU. (more…)
Django is a slave whose brutal history with his former owners lands him face-to-face with German-born bounty hunter Dr. King Schultz. Schultz is on the trail of the murderous Brittle brothers, and only Django can lead him to his bounty. The unorthodox Schultz acquires Django with a promise to free him upon the capture of the Brittles — dead or alive. Success leads Schultz to free Django, though the two men choose not to go their separate ways. Instead, Schultz seeks out the South’s most wanted criminals with Django by his side. Honing vital hunting skills, Django remains focused on one goal: finding and rescuing Broomhilda, the wife he lost to the slave trade long ago. Django and Schultz’s search ultimately leads them to Calvin Candie, the proprietor of “Candyland,” an infamous plantation. Exploring the compound under false pretenses, Django and Schultz arouse the suspicion of Stephen, Candie’s trusted house slave. Their moves are marked, and a treacherous organization closes in on them. If Django and Schultz are to escape with Broomhilda, they must choose between independence and solidarity, between sacrifice and survival… (more…)
Fashion travels quickly from ramp to street. It is no longer confined to ramp or backstage, but has gone beyond with increase in affordability. Fashion experts believe that globalization has brought a shift in fashion from being region specific to cosmopolitan.(more…)
