Microbial forensics: The next great forensic challenge

...ex, interdependent societies. The nation is in the process of developing a strong microbial forensic program to attribute and prosecute such attacks, and perhaps deter them. The opportunities and challenges facing the new field of microbial forensics will be presented at the 229th National Meeting of the Am...

Silence the gene, save the cell: RNA interference as promising therapy for ALS

...ference is part of a complex cellular housekeeping process that protects cells from invading viruses or other genetic threats. It works by interrupting messenger RNA as it transfers the genetic code for a protein from the nucleus to the site in the cell where the protein is synthesized. To trigger RNA inter...
