The beat goes on with a new model for artificial flagella

(Phys.org) —Eukaryotic flagella, whip-like organelles that elegantly propel microorganisms and pump fluid, seem to embody simplicity on the microscopic scale. But appearances can be deceptive: Flagella are composed of 650 ...

Building 'nanomachines' in biological outer space

Cambridge scientists have uncovered the mechanism by which bacteria build their surface propellers (flagella) – the long extensions that allow them to swim towards food and away from danger. The results, published this ...

Researchers discover sperm move along a 'twisting ribbon'

Astrobiologists claim meteorite carried space algae

(Phys.org) —A fireball that appeared over the Sri Lankan province of Polonnaruwa on December 29, 2012 was a meteorite containing algae fossils, according to a paper published in the Journal of Cosmology. A team of researchers, ...

Biologists produce rainbow-colored algae

What can green algae do for science if they weren't, well, green? That's the question biologists at UC San Diego sought to answer when they engineered a green alga used commonly in laboratories, Chlamydomonas reinhardtii, ...
