Immunosuppressive Drugs Are A Double-edged Sword To Type 1 Diabetics
Type 1 diabetes occurs when immune cells destroy pancreatic insulin producing beta-cells. It was hoped that islet transplantation would provide a cure for the disease, however, transplant success is short-lived and accompanied by significant side effects. New data indicate that the immunosuppressive drugs used to prevent islet transplant rejection suppress beta-cell regeneration in diabetic mice, raising the possibility that identifying immunosuppressive drugs that do not inhibit beta-cell regeneration might lead to successful regenerative islet transplantation. UF Researchers Map Bacterial Proteins That Cause Tooth Loss
The human mouth teems with millions of enamel-eroding, gum-inflaming microbes. One of these, Porphyromonas gingivalis, is a bacterial homesteader that stakes a claim deep within the spaces between teeth and gums. It's also the leading cause of tooth loss -- secreting proteins that destroy the soft tissues and bone that support teeth to cause periodontal disease.

FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." FTC Reaches New Year's Resolutions With Four Major Weight-Control Pill

Every year, the United State produces millions of scrap tires that clog landfills and become breeding areas for pests. Finding adequate uses for castoff tires is a continuing challenge and illegal dumping has become a serious problem throughout the nation. New System For Earthquake Early Warning
UC Berkeley seismologist Richard Allen has found that the frequency of P waves produced within the first four seconds of an earthquake provides enough information to estimate the ultimate magnitude of the earthquake. Using a system called ElarmS, Allen and colleagues are able to predict distant ground motion and send warnings to areas of potentially damaging shaking, providing seconds to tens of seconds of advance warning.
