Astrobiologists in Germany are developing a new testing device that could help tease dormant alien microbes into revealing ...

Chemotaxis, a process for chemically inducing movement in an organism, may be a crucial tool in the search for life on Mars.

Finding life on another planet would be a world-changing discovery for humanity. But actually detecting it is no simple task.

“One of the goals [of astrobiology] is to go to [other worlds] and look for microorganisms, but in the meantime there’s so ...

The search for alien life could be boosted by a simple new test, say scientists. They believe the movement of microbes may ...

Use precise geolocation data and actively scan device characteristics for identification. This is done to store and access ...

Finding life in outer space is one of the great endeavors of humankind. One approach is to find motile microorganisms that ...

The inflammasome is a multiprotein intracellular complex that detects pathogenic microorganisms and sterile stressors, and that activates the highly pro-inflammatory cytokines interleukin-1b (IL ...

Data presented in this useful report suggest a potentially new model for chemotaxis regulation in the gram-negative bacterium P. putida. Data supporting interactions between CheA and the ...

In the first part, several experiments were carried out to show that CsoR binds to CheA, inhibits CheA phosphorylation, and impairs P. putida chemotaxis. The second part provides some evidence that ...

Phospholipase A 2 is also activated by cAMP and is important for chemotaxis. The leading edge is extended partially by the force of dendritic actin polymerization beneath the membrane, but also ...
