We've all seen the satellite images of Earth at night--the bright blobs and shining webs that tell the story of humanity's endless sprawl.   view more (2008-11-25)

Melatonin may save eyesight in inflammatory disease
Current research suggests that melatonin therapy may help treat uveitis, a common inflammatory eye disease. The related report by Sande et al., "Therapeutic Effect of Melatonin in Experimental Uveitis," appears in the December issue of The American Journal of Pathology.   view more (2008-11-24)

Common cold virus came from birds
A virus that causes cold-like symptoms in humans originated in birds and may have crossed the species barrier around 200 years ago, according to an article published in the December issue of the Journal of General Virology. Scientists hope their findings will help us understand how potentially... view more (2008-11-20)

New tool trains athlete brains to react 53 percent faster
All great athletes know that in order to perform well, they can't just depend on their physical capabilities. Speed and efficiency in decision-making are just as essential.   view more (2008-11-19)

Hormone shows promise in reversing Alzheimer's disease and stroke
Saint Louis University researchers have identified a novel way of getting a potential treatment for Alzheimer's disease and stroke into the brain where it can do its work.   view more (2008-11-12)

Researchers discover method for mass production of nanomaterial graphene
Graphene is a perfect example of the wonders of nanotechnology, in which common substances are scaled down to an atomic level to uncover new and exciting possibilities.   view more (2008-11-11)

Urgent action on international coral reef crisis
Coral reef scientists and policy makers from the world's most prominent coral reef nations are meeting in Australia this week to develop urgent action plans to rescue the world's richest centre of marine biodiversity from gradual decline.   view more (2008-11-10)

Previously unknown immune cell may help those with Crohn's and colitis
The tonsils and lymphoid tissues in the intestinal tract that help protect the body from external pathogens are the home base of a rare immune cell newly identified by researchers at Washington University School of Medicine in St. Louis.   view more (2008-11-04)

What's the influence of laxative agents on mucosal barrier repair?
The prostone lubiprostone has been shown to stimulate chloride secretion via one of the minor intestinal epithelial channels, ClC-2. This results in sustained low-level secretion of water into the lumen.   view more (2008-11-03)

Gender Biases in Leadership Selection During Competitions Within and Between Groups
What makes a great leader? Traits that we look for typically include a sense of power, great negotiating skills and lots of charisma. However, a recent study suggests that it is not just an outgoing personality and great communication skills that determine who is chosen as leader of a group.   view more (2008-10-31)

Candidate markers for gastric cancer
The sequencing of the human genome has opened the door for proteomics by providing a sequence-based framework for mining proteomes.   view more (2008-10-29)

Building the blood-brain barrier
Construction of the brain's border fence is supervised by Wnt/b-catenin signaling, report Liebner et al. in The Journal of Cell Biology.    view more (2008-10-27)

What is the function of NOD2 in colonic epithelial cells?
NOD2 is a cytosolic pattern recognition receptor similar in structure and function to Toll like receptors (TLRs). It can recognize and respond to a component found in the cell wall of bacteria, muramyl dipeptide (MDP), and has been shown to play an important role in the innate immune response of... view more (2008-10-23)

Clue to genetic cause of fatal birth defect
A novel enzyme may play a major role in anencephaly, offering hope for a genetic test or even therapy for the rare fatal birth defect in which the brain fails to develop, according to a study from researchers at the University of Illinois at Chicago College of Medicine.   view more (2008-10-10)

Diversity of plant-eating fishes may be key to recovery of coral reefs
For endangered coral reefs, not all plant-eating fish are created equal. A report scheduled to be published this week in the early edition of the journal Proceedings of the National Academy of Sciences suggests that maintaining the proper balance of herbivorous fishes may be critical to restoring... view more (2008-10-09)

Waterborne disease risk upped in Great Lakes
An anticipated increased incidence of climate-related extreme rainfall events in the Great Lakes region may raise the public health risk for the 40 million people who depend on the lakes for their drinking water, according to a new study.   view more (2008-10-09)

Extinction by asteroid a rarity
In geology as in cancer research, the silver bullet theory always gets the headlines and nearly always turns out to be wrong.   view more (2008-10-07)

Mental barriers hamper obese women's efforts to get exercise
For arachnophobes, it's difficult to kill a spider as it scurries across the floor. Those who are scared to fly might not ever set foot on a plane. While nothing physically stops people with these aversions, a mental barrier can keep them from the task at hand.   view more (2008-10-06)

Water table depth tied to droughts
Will there be another "dust bowl" in the Great Plains similar to the one that swept the region in the 1930s?   view more (2008-09-30)

Discovered: World's Largest Tsunami Debris
A line of massive boulders on the western shore of Tonga may be evidence of the most powerful volcano-triggered tsunami found to date. Up to 9 meters (30 feet) high and weighing up to 1.6 million kilograms (3.5 million pounds), the seven coral boulders are located 100 to 400 meters (300 to 1,300... view more (2008-09-26)

New lights on the pathogenic mechanisms of liver cirrhosis with ascites
The pathogenic mechanisms implicated in the failure of intestinal barrier in cirrhosis have not been fully elucidated as yet and remains to be investigated.   view more (2008-09-24)

Modest CO2 cutbacks may be too little, too late for coral reefs
How much carbon dioxide is too much? According to United Nations Framework Convention on Climate Change (UNFCCC) greenhouse gases in the atmosphere need to be stabilized at levels low enough to "prevent dangerous anthropogenic interference with the climate system." But scientists have... view more (2008-09-23)
