Biologists from ETH Zurich have discovered speargun- like molecular injection systems in two types of bacteria and have described their structure for the first time. The special nanomachines are used ...

Similar in function to ballast tanks in submarines or fish bladders, many water-based bacteria use gas vesicles to regulate their floatability. In a new publication in Cell, scientists from the ...

Bacteria are also able to communicate with each other through chemical signals, a behavior known as quorum signaling (QS). These chemical signals spread through a biofilm that colonies of bacteria ...

As a grad student in cell biology, Shaeri Mukherjee was always on the lookout for new ways to fiddle with cells’ internal structures. It was the early 2000s, and Mukherjee was working in Dennis ...

The mucosal surfaces that line the body are embedded with defensive molecules that help keep microbes from causing ...
