Mars research subjects to emerge after 8 months of isolation

Technology
After eight months of living in isolation on a remote Hawaii volcano, six NASA-backed research subjects will emerge from their Mars-like habitat on Sunday and return to civilization. Their first order of business after subsisting on mostly freeze-dried and canned food: Feast on fresh-picked pineapple, papaya, mango, locally grown vegetables and a fluffy, homemade egg strata cooked by their project's lead scientist. The crew of four men and two women were quarantined on a vast plain below the summit of the world's largest active volcano in January. All of their communications with the outside world were subjected to a 20-minute delay — the time it takes for signals to get from Mars to Earth. They are part of a study designed to better understand the psychological effects that a long-term m

'Shape-shifting' bacteria spotted in space

Technology
Bacterial cells treated with a common antibiotic have been spotted changing shape to survive while aboard the International Space Station (ISS).The way bacteria act in near-zero gravity environments could pose a serious problem for treating astronauts with infections.The "clever shape-shifting" was detected in bacteria being experimented on in the near-weightlessness of space, and is believed to help the bacteria survive.An experiment on the common E coli bacteria subjected it to different concentrations of the antibiotic gentamicin sulfate, a drug which kills the bug on Earth.However, in comparison to a control group on Earth, the space bacteria showed a 13-fold increase in cell numbers and a 73% reduction in cell column size."We knew bacteria behave differently in space and that it takes...
