Beating bacteria on Earth—and in space

By sheer strength of numbers, bacteria are by far the most successful life form on Earth. As we've learned over the past several decades of human spaceflight, they don't do too badly in microgravity either. For evidence, ...

Colloidal suspensions of microspheres in a liquid may not be simple systems

(Âé¶¹ÒùÔº) —A colloidal suspension is a mixture in which microscopic particles of one substance are dispersed in another and because of its properties does not "settle" in the way that one might expect a stirred mixture ...
