Physiological effects of reduced gravity on bacteria
An article in Journal of Applied Microbiology investigates how bacteria respond when they are subjected to environmental alterations, such as those of space stations, which feature lowered effects of gravity. "Intra-specific differences in bacterial responses to modeled reduced gravity" by Paul W. Baker and Laura G. Leff describes differences in bacterial responses to reduced gravity and h...New gravity-flow column gives faster and simpler purification of histidine-tagged proteins
A. Bergh, M. Carlsson, A. Karlsson, and H. Lindgren GE Healthcare, Uppsala, Sweden Histidine-tagged proteins* can be quickly and simply purified on His GraviTrap columns prepacked with Ni Sepharose 6 Fast Flow without the need for a pump or purification system. The protein binding capacity (approx. 40 mg/column) is among the hi...French Surgeons Take Off for First 'Gravity-free' Surgery
A team of French surgeons took off on a specially equipped aircraft early Wednesday from Merignac Airport in Bordeaux to attempt the first-ever operation // carried out in weightless conditions, the Bordeaux University Hospital Centre (CHU) said. The Airbus A300 is equipped with a special surgical module, which could serve as a prototype for equipment used in future surgery carried o...
