Study links Greenland ice sheet collapse, sea level rise 400,000 years ago
A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some four to six meters.

Lowering toxicity of new HIV drugs predicted to improve life expectancy
While bringing new drugs to market is important for increasing life expectancy in younger people with HIV, lowering the toxicity of those drugs may have an even greater health impact on all HIV patients, a University of Pittsburgh Graduate School of Public Health analysis reveals.

Metal particles in solids aren't as fixed as they seem, new memristor study shows
In work that unmasks some of the magic behind memristors and 'resistive random access memory,' or RRAM -- cutting-edge computer components that combine logic and memory functions -- researchers have shown that the metal particles in memristors don't stay put as previously thought.

Regional anesthesia cuts length of stay, mortality vs. general anesthesia in hip fracture surgery
Patients who received regional anesthesia during hip fracture surgery had moderately lower mortality and a significantly lower length of stay than those who received general anesthesia, according to new research from the Perelman School of Medicine at the University of Pennsylvania. In a related study published in JAMA Internal Medicine this week, the team also reported high rates of mortality and functional disability among nursing home residents treated for hip fracture.

Learning and Memory
UCI study finds that learning by repetition impairs recall of details
UC Irvine neurobiologists Zachariah Reagh and Michael Yassa have found that while repetition enhances the factual content of memories, it can reduce the amount of detail stored with those memories. This means that with repeated recall, nuanced aspects may fade away.

Long non-coding RNAs can encode proteins after all
Case Western Reserve School of Medicine scientists have made an extraordinary double discovery. First, they have identified thousands of novel long non-coding ribonucleic acid transcripts. Second, they have learned that some of them defy conventional wisdom regarding lncRNA transcripts, because they actually do direct the synthesis of proteins in cells. Both of the breakthroughs are detailed in the June 12 issue of Cell Reports.

Measuring the mass of 'massless' electrons
Graphene, a one-atom-thick carbon sheet, has taken the world of physics by storm -- in part, because its electrons behave as massless particles. Yet these electrons seem to have dual personalities.

Church-going is not enough to affect job satisfaction and commitment, Baylor study finds

Neurons get their neighbors to take out their trash
Biologists have long considered cells to function like self-cleaning ovens, chewing up and recycling their own worn out parts as needed. But a new study shows that some nerve cells found in the eye pass off their old energy-producing factories to neighboring support cells to be 'eaten.' The find, which may bear on the roots of glaucoma, also has implications for Parkinson's, Alzheimer's, amyotrophic lateral sclerosis and other diseases that involve a buildup of 'garbage' in brain cells.

UV-induced beta-endorphin production causes addiction-like symptoms in mice
A new study from Massachusetts General Hospital investigators adds important support to the theory that ultraviolet light can actually be addictive, finding that chronic UV exposure raises circulating levels of beta-endorphin in mice and that UV-habituated mice exhibit withdrawal symptoms if beta-endorphin activity is blocked.

Evolution depends on rare chance events, 'molecular time travel' experiments show
While historians can only speculate on what might have been, a team of evolutionary biologists studying ancient proteins has turned speculation into experiment. They resurrected an ancient ancestor of an important human protein as it existed hundreds of millions of years ago and then used biochemical methods to generate and characterize a huge number of alternative histories that could have ensued from that ancient starting point.

Familiar yet strange: Water's 'split personality' revealed by computer model
Using computer models, Princeton University researchers found that as water freezes it takes on a sort of split personality wherein, at very cold temperatures and above a certain pressure, it may spontaneously split into two liquid forms. Finding this dual nature could lead to a better understanding of how water behaves in high-altitude clouds, which could improve the predictive ability of current weather and climate models.
