Shh! Don't wake the sleeping virus!
Scientists at Bar-Ilan University report on a novel experimental model that, for the first time, successfully mimics the 'sleeping' and 'waking' of the varicella-zoster virus. Based on neurons generated from human embryonic stem cells, and not requiring the use of experimental animals, the model allows scientists to test drugs and develop therapies to prevent shingles. It may also contribute to the fight against other viruses -- such as herpes and polio -- that target the human nervous system.

Vanishing friction
Physicists at MIT have developed an experimental technique to simulate friction at the nanoscale. Using their technique, the researchers are able to directly observe individual atoms at the interface of two surfaces and manipulate their arrangement, tuning the amount of friction between the surfaces. By changing the spacing of atoms on one surface, they observed a point at which friction disappears.

Cheating amoebas reveal key to successful societies
Nobody likes a cheater. In a recent study, a University of Houston evolutionary biologist and her collaborators found that while cheaters do not take over populations, they also cannot ever fully be removed. Supported by grants from the National Science Foundation, the findings are described in a paper appearing June 15 in Current Biology.

Warmer, lower-oxygen oceans will shift marine habitats
Warming temperatures and decreasing levels of dissolved oxygen will act together to create metabolic stress for marine animals. Habitats will shift to places in the ocean where the oxygen supply can meet the animals' increasing future needs.

Planarian regeneration model discovered by artificial intelligence
An artificial intelligence system has for the first time reverse-engineered the regeneration mechanism of planaria -- the small worms whose power to regrow body parts makes them a research model in human regenerative medicine. The discovery presents the first model of regeneration discovered by a non-human intelligence and the first comprehensive model of planarian regeneration, which has eluded human scientists for a century.

Sudden draining of glacial lakes explained
In 2008 scientists from Woods Hole Oceanographic Institution and the University of Washington documented for the first time how the icy bottoms of lakes atop the Greenland Ice Sheet can crack open suddenly -- draining the lakes completely within hours and sending torrents of water to the base of the ice sheet thousands of feet below. Now they have found a surprising mechanism that triggers the cracks.

Paleo study shows how elevation may affect evolution
About 34 million years ago, global temperatures took a dive, causing a sudden wave of extinctions among European mammals. In North America, however, life went on largely unscathed. A new study explains why: the rise of the Rocky Mountains had forced North American mammals to adapt to a colder, drier world.

Trouble in the tide pools
A harmful algal bloom is the suspected culprit of a die-off in 2011 of millions of purple sea urchins and six-starred sea stars in Northern California. Their disappearance is predicted to have long-term ecological consequences on their populations. As algal blooms are expected to increase with climate change and ocean acidification, similar mass mortality events are expected to increase.

Researchers simulate behavior of 'active matter'
From flocks of starlings to schools of fish, nature is full of intricate dynamics that emerge from the collective behavior of individuals. In recent years, interest has grown in trying to capture similar dynamics to make self-assembling materials from so-called 'active matter.' Researchers from Brown University have shed new light on the dynamics of one type of active matter known as active colloids.

Coupled human and natural systems explain change on the Mongolian Plateau
Using well-established metrics of social, economic, and ecosystem functions, researchers have achieved a holistic view of coupled human and natural systems on the Mongolian Plateau. This view reveals a dynamic system of interacting factors, with widely varied results in the plateau's two geopolitical regions.

At peak fertility, women who desire to maintain body attractiveness report they eat less
Women near peak fertility -- those nearing ovulation -- and who are motivated to manage their body appearance, reported they desire to lose weight and so ate fewer calories. Those are findings from three new independent studies, says lead author Andrea Meltzer, Southern Methodist University, Dallas. Previous ovulation research has attributed reduced eating solely to neuroendocrinological factors. The new findings indicate an additional factor is a woman's concern about her body appearance, say Meltzer and her co-authors.
