Buckling up to turn

Buckling up to turn | Biosciencia News | Scoop.it
Bacteria swim by rotating the helical, hairlike flagella that extend from their unicellular bodies. Some bacteria, including the Escherichia coli (E.
Biosciencia's insight:

Now, using high-speed video to record individual swimming bacteria at up to 1,000 frames per second, researchers at MIT have seen that the flick occurs when the so-called “hook,” a small flexible rod connecting the flagellum to the cell’s internal motor, buckles during forward swims.

Bacterium Planococcus halocryophilus Offers Clues about Microbial Life on Enceladus, Mars | Biology, Space Exploration | Sci-News.com | Biosciencia News | Scoop.it
Bacterium Planococcus halocryophilus that is able to thrive at minus 15 degrees Celsius offers clues about microbial life on both Mars and Enceladus.
Biosciencia's insight:

A novel aerobic, gram-positive bacterium that is able to thrive at minus 15 degrees Celsius  - the coldest temperature ever reported for bacterial growth – offers clues about microbial life on both Mars and the Saturn moon Enceladus, where similar briny subzero conditions are thought to exist, says a McGill University-led team of researchers.
