Brain tells signs from pantomime
Different brain areas light up when deaf people use American Sign Language than when they gesture.

Rapid HIV treatment could slow growing TB rates
Widespread yearly testing and immediate treatment with antiretroviral drugs could avert more than 6 million tuberculosis cases in Africa, a new model finds.

IVF kids show shift in gene activity
Team finds differences related to metabolism and growth.

Possible prostate cancer culprit
Scientists identify a type of stem cell and a gene that play a role in the disease.

Climate science: Credibility at risk, scientists say
Publication of hacked emails exchanged by climate scientists. News accounts of problems in vetting data used in climate-assessment reports. Charges by critics that scientists won’t release their raw data so that others might independently vet published analyses of climate trends. Taken together, these events have marred the reputations of climate scientists, the Intergovernmental Panel on Climate Change and perhaps science generally. Or so concluded a distinguished panel of science luminaries.

Finding coolable hot spots for crime
Some high-risk areas are easier to manage than others, a new model suggests.

Healthy teeth, healthy people
Talk leaves journalists flossing for details on oral health.
- Health & Medicine
Brain at the breaking point
New research, showing how stresses can snap tiny tracks inside brain connections, may improve understanding of traumatic brain injury.
- Tech
Leasing car batteries to the power company
Most people, on average, drive their cars only an hour or two a day. The rest of the time, those pricey vehicles sit parked on the street or in some garage. But if those cars had a big bank of batteries – typical of today’s gasoline hybrids or soon-to-hit-the-road plug-in hybrids – they could be earning their owners money while sitting parked. Maybe $5 to $10 a day, just by serving as a back-up energy-storage system for the electric-utility grid.

Dolphins may offer clues to treating diabetes
Insulin-resistance switch helps maintain glucose levels in dolphin brains, suggesting possible clues to treating diabetes in people.

Tumor tracking gets personal
A new method has the potential to use genome science to improve cancer care.

Lunch time for stem cells
Kristen Brennand is trying to tease out how the cells in brains of healthy people differ from those in schizophrenic patients. The problem: No one wants to give up a chunk of brain for her to study. So she’s fashioning her own clumps of brain cells from tissue people willingly part with – skin.
