P. sojae was chosen for the project because it has a compact genome, and because researchers have been studying its genetics for many years. Dr. Brett Tyler, Dr. Bruno Sobral, and their colleagues at the VBI ...Stanford researchers develop gene therapy technique that sharply cuts risks
...vised a new gene therapy technique that appears to eliminate one of the major health risks linked to gene therapy. The technique, published in the Oct. 15 advanced online edition of the journal Nature Biotechnology, overcomes the need for viral vectors that have plagued gene therapy trials, while retaining the...Shadow proteins in thymus - Clues to how immune system works?
...uspects the processes are similar to those used to eliminate T cells that react to ubiquitous or circulating proteins. Nor is it clear how aire controls the expression of so many shadow proteins. One possibility is that it works by binding to other transcription factors. "It is going to be interesting to figur...Understanding acetaminophen poisoning
...increases its ability to modify such compounds and eliminate them from the body. This is normally a protective response. In some cases, however, it can also result in harmful effects, for example by increasing the production of toxic byproducts like NAPQI. Using a mouse bred to lack CAR, Moore and his c...Gene's role in malaria drug resistance proved
...transmits malaria. Chloroquine helped control or eliminate malaria throughout much of the world when it became widely used in the years following World War II.

...hole process of disease resistance in plants could eliminate the need for fungicides or bacteriocides." When disease strikes a plant, its immune system sends up a warning "flare" telling different areas of the plant to resist infection.

In France, information on race is seldom collected officially, but evidence of systematic racial discrimination remains. In Brazil, the nati...Scientists use alfalfa plants to harvest nanoparticles of gold
