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…

Researchers believe they have solved a mystery that has puzzled evolutionary scientists for years ... if 'good' genes spread through the population, why are individuals so different?  The so…

The good news: improved health care is reducing occurrences of intestinal parasites worldwide. The bad news: at the same time, rates of asthma are increasing worldwide. The link between these trends…

Biology and chemistry researchers from Virginia Tech are creating molecular complexes to bind to and disrupt the DNA of diseased tissues, such as tumors or viruses. Testing the activity of each of…

For the first time, researchers have used adult bone marrow stem cells to regenerate healthy human liver tissue, according to a study published in the April issue of the journal Radiology. When…

The Himalaya, the “Roof of the World”, source of the seven largest rivers of Asia are, like other mountain chains, suffering the effects of global warming. To assess the extent of melting of its 33…

Some day, heart attack survivors might have a patch of laboratory-grown muscle placed in their heart, to replace areas that died during their attack. Children born with defective heart valves might…

The validity of a leading theory that has held a glimmer of hope for unraveling the intricacies of the brain has just been called into question. Dr. Ilan Lampl of the Weizmann Institute of Science's…

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are trying to design catalysts inspired by photosynthesis, the natural process by which green plants convert…

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…

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…

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…
