Children's Hospital researchers identify molecular 'switch' that could save very young lives
A team of researchers at Children's Hospital of Pittsburgh of UPMC have identified a molecular "switch" that, when blocked, may help reverse necrotizing enterocolitis (NEC), a leading cause of death in premature infants. view more (2007-12-05)
Researchers identify molecular basis of inflammatory bowel disease
Inflammatory bowel diseases, such as Crohn's disease and Ulcerative Colitis, severely impair the lives of more than four million people worldwide. The development of effective therapies against these diseases requires an understanding of their underlying molecular mechanisms. Researchers from the Universities of Cologne and Mainz in Germany, the... view more... (2007-03-15)
Scientists Use MicroRNAs to Track Evolutionary History for First Time
The large group of segmented worms known as annelids, which includes earthworms, leeches and bristle worms, evolved millions of years ago and can be found in every corner of the world. view more (2009-09-10)
Parasitic worms make sex worthwhile
The coevolutionary struggle between a New Zealand snail and its worm parasite makes sex advantageous for the snail, whose females favor asexual reproduction in the absence of parasites, say Indiana University Bloomington and Swiss Federal Institute of Technology biologists in this week's Current Biology. view more (2009-07-24)
Researchers identify antibiotic protein that defends the intestine against microbial invaders
Researchers at UT Southwestern Medical Center have identified a protein that is made in the intestinal lining and targets microbial invaders, offering novel insights into how the intestine fends off pathogens and maintains friendly relations with symbiotic microbes. view more (2006-08-25)
The bizarre lives of bone-eating worms
The females of the recently discovered Osedax marine worms feast on submerged bones via a complex relationship with symbiotic bacteria, and they are turning out to be far more diverse and widespread than scientists expected. view more (2009-11-10)
Oregon researchers show how resident bacteria shape gut development
University of Oregon researchers have shown that bacteria residing in the intestine shape gut development by means of several distinct signaling mechanisms. view more (2006-06-22)
New intestinal disease charted by Swedish researcher
Microscopic colitis is a newly discovered inflammatory intestinal disease that occurs in two different forms, lymphocytary colitis and collagenic colitis. Ã-rebro University, Sweden, is on the cutting edge of research on these diseases, and Martin Olesen is one of first scientists in the country to write a dissertation on the subject, defending... view more...

Natural protein may halt colorectal cancer's spread
Medical College of Wisconsin Cancer Center researchers in Milwaukee have learned that a protein, CXCL12, that normally controls intestinal cell movement, has the potential to halt colorectal cancer spreading. view more (2009-04-21)
Scientists find how bacteria in cows milk may cause Crohn's disease
Scientists at the University of Liverpool have found how a bacterium, known to cause illness in cattle, may cause Crohn's disease in humans. view more (2007-12-11)
Stomach cancer rate set to fall further 25 percent over next decade
New cases of stomach cancer are set to plummet a further 25 per cent in the West over the next decade, indicates research published ahead of print in the journal Gut. view more (2007-08-14)
Forget the antioxidants? McGill researchers cast doubt on role of free radicals in aging
For more than 40 years, the prevailing explanation of why we get old has been tied to what is called oxidative stress. This theory postulates that when molecules like free radicals, oxygen ions and peroxides build up in cells, they overwhelm the cells' ability to repair the damage they cause, and the cells age. view more (2009-02-18)
New Lifespan Extension Genes Found
New genes tied to lifespan extension in yeast have been identified by researchers from UC Davis and Harvard Medical School. view more (2005-10-03)
BA Festival: Asthma and the Sinister Infiltrator
Professor Tim Williams, head of the Leukocyte Biology Section, Imperial College School of Medicine, will tell the BA Festival of Science on Tuesday 12 September how asthma may be caused primarily by a body defence system that has gone wrong - when allergens in the air are mistaken by the body for products from parasitic worms. Professor Williams... view more... (2000-09-12)
JDRF funded study links 'hygiene hypothesis' to diabetes prevention
A research study funded by JDRF suggests that a common intestinal bacteria may provide some protection from developing type 1 diabetes. The findings provide an important step towards understanding how and why type 1 diabetes develops in people, and may lead to potential cures. view more (2008-10-07)
Researchers find level of special protein is critical to proper formation of muscles
Proper formation of the proteins that power heart and skeletal muscle seems to rely on a precise concentration of a "chaperone" protein known as UNC-45, according to a new study. view more (2007-04-25)
UCLA cancer researchers first to link intestinal inflammation with systemic chromosome damage
UCLA scientists have linked for the first time intestinal inflammation with systemic chromosome damage in mice, a finding that may lead to the early identification and treatment of human inflammatory disorders. view more (2009-06-01)
Landmark UNC-led study finds radiofrequency ablation is effective treatment for Barrett's esophagus
A landmark clinical trial led by a University of North Carolina at Chapel Hill researcher concludes that radiofrequency ablation is an effective treatment for dysplasia in people with Barrett's esophagus, a condition that can lead to deadly gastrointestinal cancer. view more (2009-05-28)
Bacterial Protein Shows Promise in Treating Intestinal Parasites
Scientists at the University of California, San Diego and Yale University have discovered that a natural protein produced by Bacillus thuringiensis, a bacterium sprayed on crops by organic farmers to reduce insect damage, is highly effective at treating hookworm infections in laboratory animals. view more (2006-09-26)
Worms control lifespan at high temperatures, UCSF study finds
The common research worm, C. elegans, is able to use heat-sensing nerve cells to not only regulate its response to hotter environments, but also to control the pace of its aging as a result of that heat, according to new research at the University of California, San Francisco. view more (2009-04-17)
