Why doesn't the immune system attack the small intestine?

...ith so many millions of bacteria cells and so much opportunity for dendritic cells to stimulate an immune attack, it's remarkable that intestinal tissue is so rarely the target of an immune attack. Our findings demonstrate that the immune system has features that remain to be discovered." ...

'Night owls' report more insomnia-related symptoms

...ptoms related to insomnia, despite many having the opportunity to compensate for their nocturnal sleeplessness by extending their time in bed and being able to gain more total sleep time, according to a study published in the April 15th issue of the Journal of Clinical Sleep Medicine (JCSM).

Scientists find potential 'off-switch' for HIV virus

...hibernates, relatively harmlessly, but awaiting an opportunity to re-emerge and wreak havoc. Weinberger and Shenk studied how an HIV protein, called Tat, plays a major part in initiating and also interrupting the cascade of chemical reactions that leads to full-blown infection. Based on their work and previou...

New biofuels process promises to meet all US transportation needs

...eduction of land area needed for H2CAR provides an opportunity for sustainable production of hydrocarbon fuel for the foreseeable future," Agrawal said. A major reason less land would be needed is because of the overall higher efficiency of generating hydrogen by splitting water molecules using solar energy t...

Old dinosaur research leads to new honor

...e he usually studies. "I had a special research opportunity through NSERC to pursue this, and never expected it would be that successful. In fact, there will soon be an interpretive centre at the site where we found the embryos ?the Golden Gate Highlands National Park in South Africa. It certainly is an honou...

DNA analysis reveals rapid population shift among Pleistocene cave bears

...isruption in the cave bear population, creating an opportunity for the infiltration by a neighboring cave bear group. The authors note that though the new bears successfully colonized the Ach Valley for a time, they endured only another 2,000 years before becoming extinct in the region. ...

Viral protein is an effective preventative against infection

...pper respiratory infection, the bacteria seize the opportunity and migrate to the middle ear, causing a secondary infection. The new treatment would kill the bacteria before it had a chance to move. "These bacteria take advantage of a viral infection by striking when our resistance is lowered," says Fischetti...

Army research mission focused on autism

... the focus of the ASDRP. "This is a very unique opportunity to allow the scientists and advocates to focus on a common cause, improving the lives of children with autism, to produce research that will lead to making a real difference," said Peter Bell, executive vice president of Autism Speaks, who also has a...
