Two studies on bee evolution reveal surprises
A 100-million-year-old bee fossil and a DNA study suggest that bees may have originated in the Northern rather than the Southern Hemisphere and from a different family of bees than previously thought.

Researchers in Montréal and the US create model of key immune-system component
Researchers at Université de Montréal, working with teams at Massachusetts General Hospital and Johns Hopkins University, have made a major breakthrough in understanding an essential aspect of the immune system.

Beyond silicon: MIT demonstrates new transistor technology
MIT engineers have demonstrated a technology that could introduce an important new phase of the microelectronics revolution that has already brought us iPods, laptops and much more.

Why teens do stupid things
Teens take a lot of risks, but not because they think they're invulnerable or haven't thought about the consequences.

Graduate students study links between African and US weather systems
When their DC-8 flew into a tropical storm off the coast of West Africa, Aaron Pratt and Tamara Battle realized their lifelong dream -- to study storms and weather systems at their source.

Unusually stable glasses may benefit drugs, coatings
A new approach to making remarkably stable glassy materials from organic molecules, developed by researchers from the University of Wisconsin-Madison and the NIST Center for Neutron Research, could lead to novel coatings and to improvements in drug delivery.

When the label says 'low fat,' calories can pile up, study says
People -- especially overweight people -- consume up to 50 percent more calories when they eat low-fat versions of snack foods than when they eat the regular versions, finds a study by Cornell's Brian Wansink.

Queen bee promiscuity boosts hive health
Though promiscuity may be risky behavior for humans, it's healthy for honeybees: Queen honeybees who indulge in sexual surfeits with multiple drones produce more disease-resistant colonies than monogamous monarchs, according to a new study.

New research published in Ecology Letters offers an explanation for why numbers of many countryside bird species continue to decline, despite Government financial support for farmers to improve their habitat through agri-environment schemes.

Patients' requests for antidepressants can influence physician evaluation of depression
Patients who initiate a general discussion about the need for antidepressant medication with their primary-care physician are more likely to be thoroughly evaluated for depression than those who make a brand-specific request or no request, according to a new study in the December issue of Medical Care.
