Meteorites smacking into the early Earth could have created warm, watery environments favorable to primordial life. A new study of an impact crater in Finland suggests that such hydrothermal activity could have lasted up to 1.6 million years — at least 10 times longer than theory suggested, providing plenty of time for life to emerge and spread. 03.01.13 | more >>

High above Earth’s surface float two rings of energetic charged particles, and for about four weeks in September, they were joined by a third. The temporary ring may have formed in response to a solar shock wave that passed by Earth, researchers report online February 28 in Science. 02.28.13 | more >>

The Vulcan mind meld is no longer the stuff of science fiction. Scientists have electronically linked the brains of pairs of rats, enabling one to apparently share information with the other. And unlike the Vulcan technique, there’s no need for close contact: Using an Internet connection, one rat in Brazil sent signals to the brain of a rat in North Carolina. 02.28.13 | more >>

If someone shouts “look behind you,” tadpoles in Michael Levin’s laboratory may be ready. The tadpoles can see out of eyes growing from their tails, even though the organs aren’t directly wired to the animals’ brains, Levin and Douglas Blackiston, both of Tufts University in Medford, Mass., report online February 27 in the Journal of Experimental Biology. 02.28.13 | more >>

SAN ANTONIO — For people with a dairy allergy, gulping down a glass of milk is unthinkable. But many patients came away with that ability after a months-long program of exposure to increasing amounts of milk, researchers from Israel reported February 24 at a meeting of the American Academy of Asthma, Allergy and Immunology. 02.27.13 | more >>

WASHINGTON — Discerning one lipstick from the next can be tough for consumers but it’s even harder for scientists. Now forensics researchers have found a quick method to tell apart individual lipsticks, no matter the color or brand. The approach could help investigators analyze evidence in cases in which a smear of lipstick on glass, paper or a piece of clothing becomes important. 02.26.13 | more >>

Mouse brain cells scamper close to eternal life: They can actually outlive their bodies. Mouse neurons transplanted into rat brains lived as long as the rats did, surviving twice as long as the mouse’s average life span, researchers report online February 25 in the Proceedings of the National Academy of Sciences. 02.25.13 | more >>

SAN ANTONIO — Bad actors in air pollution may contribute to asthma and allergy by subverting protective cells in the body that tone down immune reactions, researchers report. The pollution components also seem to rev up overactive immune warriors — already linked to allergies — that need no such prompting. 02.25.13 | more >>

A stalagmite’s past may help reveal Earth’s future. By studying Siberian cave formations as old as 500,000 years, researchers have found that even moderate climate warming may set off significant thawing of permafrost. 02.25.13 | more >>

Like the sun, insulin levels rise and fall in a daily rhythm. Disrupting that cycle may contribute to obesity and diabetes, a new study suggests. 02.22.13 | more >>
