There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Moran Frenkel-PinterLife on Earth is complex and varied, but every living organism on the planet builds its proteins from the same set of 20 amino acids. All proteins in a human body, for example, are made up of some combination of the 20 common amino acids. But how exactly did that happen? Chemists say they might finally have some answers. ... “The research helps us understand how positively charged peptides could have formed on the pre-biotic earth,” says Moran Frenkel-Pinter, Ph.D., in the press statement. Frenkel-Pinter, a postdoctoral fellow at Georgia Tech, is the first author of the accompanying paper published in the Proceedings of the National Academy of Sciences.
