Defense peptide found in primates may block some human HIV transmissions

...aniell has developed a similar approach to growing anthrax vaccine in tobacco plants. An inexpensive way to produce the drug with only a small amount of tobacco would help to make it accessible in areas such as Southeast Asia, Africa and the Caribbean where the disease spreads most quickly. "If we could ...

Basic work on E. coli identifies two new keys to regulation of bacterial gene expression

...tion, such as bacteria that cause cholera, produce anthrax toxin or lead to ulcers and stomach cancer." Scientists use model organisms because they are relatively easy to work with and because there is a vast amount of previous knowledge about them. They can then test whether their findings in model organis...
