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

Physicists and biologists challenge a prevailing evolutionary theory that single-celled organisms can only evolve to become multicellular life forms if doing so increases their overall productivity.
“Rather than each cell producing what it needs, specialised cells need to be able to trade with each other. Previous work suggests that this only happens as long as the overall group’s productivity keeps increasing,” explains lead author David Yanni, PhD student at Georgia Institute of Technology, Atlanta, US.
