With the emergence of an epidemic of obesity and type 2 diabetes (DM) throughout the world, the association of lifestyle habits that may affect the risk of metabolic diseases is especially important. Most prospective studies have shown that moderate drinkers tend to have about 30% lower risk of developing late onset diabetes than do non-drinkers, and moderate drinkers also tend to be at lower...

Biomedical engineers at UC Davis have developed a plug-in interface for the microfluidic chips that will form the basis of the next generation of compact medical devices. They hope that the "fit to flow" interface will become as ubiquitous as the USB interface for computer peripherals.
Can a road-trip across eastern North America, ancient ice sheets, and DNA samples unlock the ancestral history of jack pine trees? Julie Godbout and colleagues from the Université Laval, Quebec, Canada, certainly hoped that driving across northeastern U.S. and Canada to collect samples from jack pine trees would shed some light on how glaciers may have impacted present-day pine genetics.
From a drab office in this ultra-Orthodox Jewish stronghold, three devout young women hunch over computers and surf the Internet - looking for pornography, celebrity gossip and a laundry list of other items banned by their rabbis.

It's an almost automatic decision, as though we instinctively know how to keep ourselves safe.
Breast cancers that arise sporadically, rather than through inheritance of certain genes, likely start with defects of DNA repair mechanisms that allow environmentally triggered mutations to accumulate, according to researchers at the University of Pittsburgh School of Medicine, Magee-Womens Hospital of UPMC and the University of Pittsburgh Cancer Institute. The findings, reported this week in the...
A new study by researchers at the Walter and Eliza Hall Institute in Melbourne, Australia, has shown that mature blood cells can communicate with, and influence the behaviour of, their stem cell 'parents'.

(Santa Barbara, Calif.) Scientists can use cylinders as small as teapots to study the mechanisms involved in powerful hurricanes and other swirling natural phenomena.
Whitehead Institute researchers have shown in mouse models that overexpression of the microRNA 125b (miR-125b) can independently cause leukemia and accelerate the disease's progression. Their results are published in this week's online edition of the Proceedings of the National Academy of Sciences (PNAS).
Health care costs and expenditures are expected to rise over the next decade or two and governments need methods to publicly finance these costs, states an analysis in CMAJ (Canadian Medical Association Journal).
A drilling rig bit into the bed of California's biggest river, hauling up sage-green tubes of clay and sand the consistency of uncooked fudge.
Gold nanoparticles, tiny pieces of gold so small that they can't be seen by the naked eye, are used in electronics, healthcare products and as pharmaceuticals to fight cancer. Despite their positive uses, the process to make the nanoparticles requires dangerous and extremely toxic chemicals. While the nanotechnology industry is expected to produce large quantities of nanoparticles in the near...
