Man-made Proteins Could Be More Useful Than Real Ones
Researchers have constructed a protein out of amino acids not found in natural proteins, forming a complex, stable structure closely resembling a natural protein. Their findings could help scientists design drugs that look and act like real proteins but won't be degraded by enzymes or targeted by the immune system, as natural proteins are. Rules To Target RNA Are Focus Of Research
Finding compounds that bind to and inhibit an RNA sequence -- as a potential new approach to designing disease treatments -- is still very much a trial-and-error process, involving the tedious screening of millions of molecules against a single RNA sequence. Now, a University at Buffalo medicinal chemist is hoping to change that. Engineers: In Big Picture, Gas, Cordless Mowers Equal Polluters
A new study by University of Florida engineers confirms that traditional gas-powered mowers belch far more smog-forming pollution than battery-powered or corded mowers. But the study, described in an article in the current issue of Environmental Engineering Science, also finds that lead pollution stemming from production of the battery in cordless mowers may contribute significantly more carcinogens and other toxins to people and the environment. Teens and Technology: Youth Are Leading the Transition to a Fully Wire

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.

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." Scientists Use Transcription Factors To Increase Insulin Production In
A group of Japanese scientists has used gene therapy to deliver three insulin transcription factors, MafA, PDX-1, and NeuroD, to the livers of diabetic mice. As a result, the mice experienced an increase in insulin gene expression and insulin production, raising the possibility that this could eventually be used to treat diabetes. The Impeachment Trial of President Andrew Johnson: Supplement to the C

A study released today by the University of Minnesota's "Project EAT"(Eating Among Teens) shows startling results of 2,500 female teenagers studied over a five-year period. The study found that high school-aged females' use of diet pills nearly doubled from 7.5 to 14.2 percent. By the ages of 19 and 20, 20 percent of females surveyed used diet pills. Creating Males With Female Sex Chromosomes: Brain Gene Flicks The Swit
