The emerging field of metagenomics, where the DNA of entire communities of microbes is studied simultaneously, presents the greatest opportunity -- perhaps since the invention of the microscope --…

Is that pain in your chest a heart attack or indigestion? New research from Wake Forest University School of Medicine reveals that more areas of the brain than previously thought are involved in…

Virginia Tech chemists are looking for biobased alternatives and environmentally friendly reaction pathways to replace a toxic intermediate that is a critical component of many polymer products.…

Common bacteria with an overt reaction to toxins that cause oxidative stress show promise as a biosensor to predict public health threats. At the 233rd American Chemical Society national meeting in…

Platinum might outweigh gold in the jewelry market, but as part of an ongoing effort to produce efficient and affordable fuel cells, scientists at the U.S. Department of Energy's (DOE) Brookhaven…

A mother’s high beef consumption while pregnant was associated with lower sperm counts in her son, according to a study led by researchers at the University of Rochester. Researchers sought to…

People are mixing supplements, herbs and over-the-counter medications and prescription drugs to cure themselves of ills, unaware that they could be making themselves sicker, says George Grossberg, M…

A new climate modeling study forecasts the complete disappearance of several existing climates in tropical highlands and regions near the poles, while large swaths of the tropics and subtropics may…

An odd, six-sided, honeycomb-shaped feature circling the entire north pole of Saturn has captured the interest of scientists with the Cassini mission. This atmospheric feature was already imaged by…

Yesterday, I gave my first talk at the March07 ACS meeting on Teaching Organic Chemistry with Blogs and Wikis. The screencast is now available. It was part of a symposium on Using Social Networking…

Nanomechanical oscillators -- tiny strips of vibrating silicon only a few hundred atoms thick -- are the subject of extensive study by nanotechnology researchers. They could someday replace bulky…

A pioneering “biofuel cell” that produces electricity from ordinary air spiked with small amounts of hydrogen offers significant potential as an inexpensive and renewable alternative to the costly…

An international team of researchers has discovered that two types of plant proteins are at work in the transport of an important growth hormone, a finding that could have applications in creating…

Gene therapy - the idea of using genetic instructions rather than drugs to treat disease - has tickled scientists' imaginations for decades, but is not yet a viable therapeutic method. One sizeable…

Researchers in Japan have developed a pair of molecular-scale scissors that open and close in response to light. The tiny scissors are the first example of a molecular machine capable of…

The medication tilarginine, a drug that was believed could be beneficial for patients who develop cardiogenic shock (low blood pressure due to impaired cardiac function) after a heart attack, did…

High concentrations of nitrogen dioxide gas — inhaled for even very brief periods following fires, explosions of military munitions or detonations of terrorist devices — could cause serious lung…

Researchers at the U.S. Department of Energy’s Ames Laboratory are employing some modern day alchemy in an effort to find a material with properties of rare and high-priced palladium. If they’re…

Web 2.0 + Medicine = Medicine 2.0. You must have read the BMJ article: How Web 2.0 is changing medicine. I’ve been searching for med 2.0 links for days now, and I hope you’ll like them. Some of them…

Although intelligence is generally thought to play a key role in children's early academic achievement, aspects of children's self-regulation abilities—including the ability to alternately shift and…
