U-M scientist to talk about tissue engineering at AAAS
Scientists have a pretty good handle on how to teach human cells to do tricks in a laboratory -- things like getting soft cells from the mouth's lining to form bone.

Ultra-cold temperature physics opens way to understanding and applications
Researchers doing ultra-cold temperature physics may not have to wear parkas, but they are producing the coldest temperatures ever and exploring model quantum systems that might lead to more accurate clocks and gyroscopes, quantum computers and communications as well as a better understanding of quantum physics phenomena.

A new technique developed at Georgia Tech can help reveal better ways to heal and regenerate bones using microcomputed tomography (micro-CT) imaging.

Climate change to bring a wave of new health risks
According to Jonathan A. Patz, as the world's climate warms, and as people make widespread alterations to the global landscape, human populations will become far more vulnerable to heat-related mortality, air pollution-related illnesses, infectious diseases and malnutrition.

Psychiatric disorders greatly underdiagnosed in hospital emergency departments
New research offers dramatic evidence of how psychiatric disorders are underdiagnosed in hospital emergency departments, affecting an increasing number of Americans who rely on such facilities for much of their primary health care needs.
