A little to the left … ahhhhhhhhhh!
JOHNS HOPKINS (US)—Scratching below the surface of a troublesome sensation that’s equal parts tingle-tickle-prickle, sensory scientists from Johns Hopkins University have discovered in mice a molecular basis for nonallergic itch. (more…)

To sniff out muscle repair, follow the nose
EMORY (US)—When muscle cells need repair, it turns out they use odor-detecting tools found in the nose to start the process. And if it weren’t for a team of—ahem—nosy researchers, it’s a connection that could have continued to go unnoticed. (more…)

AIDS forerunner hijacked animal gene
U. ROCHESTER (US)—An ancestor of the AIDS virus hijacked an entire gene—perhaps from some prehistoric cat it had infected. Researchers say the gene makes it easier for the virus to infect humans. (more…)

Neurons mature rapidly at birth
DUKE (US)—At the moment a newborn switches from amniotic fluid to breathing air, another profound shift occurs: nerve cells in the brain convert from hyperexcitability to a calm frame against which outside signals can be detected. (more…)

Depression may raise heart disease risk
EMORY (US)—Depression tends to reduce coronary flow reserve, resulting in a greater risk of heart disease for people who suffer from it, according to a new study. The findings also suggest genetic susceptibility influences which individuals have an increased risk. (more…)

Making heads or tails of lowly worm
YALE (US)—A group of researchers is using microRNA genes to untangle the history of the large—and still largely misunderstood—group of segmented worms known as annelids, which evolved millions of years ago and can be found in every corner of the world. (more…)

Gene has breeders counting sheep
“I think it’s very exciting. We only have one gene, but it’s definitely a tool that farmers can use,” says Raluca Mateescu, a member of the research team that has discovered a gene that prompts ewes to breed out of season.

Quantum dots catch cancer early
In this illustration, quantum dots are depicted as gold spheres that attract DNA strands linked to cancer risks. When the quantum dots are exposed to certain types of light, they transfer the energy to fluorescent molecules, shown as pink globes, that emit a glow. This enables researchers to detect and count the DNA strands linked to cancer. (Credit: Yi Zhang/ Johns Hopkins University)

Nature? Nurture? Or simply neither?
“This is one attempt at getting the ideas out there and starting a dialogue, continuing to educate the public and the scientific community, especially the younger generation of researchers,” psychologist Mark Blumberg explains. “We know we don’t have a sound bite that’s as clean and simple and sexy as saying ‘it’s genetic.’ But we’re working on it.”

Gene linked to aggression in disabled adults
“Problem behaviors in these populations account for billions of dollars in intervention costs each year, but nearly all of these interventions occur after the fact,” says study coauthor Craig Kennedy.
