Could Genetically Engineered Bacteria in Your Colon Replace Vitamins?

It's easy to forget how horrifying the effects of a vitamin deficiency can be. Each year, up to 500,000 children in the developing world go blind from lack of vitamin A, half of whom will then die within 12 months. The molecule that could save their lives is so well-studied and abundant, yet we haven't figured out how… » 2/04/15 2:40pm 2/04/15 2:40pm

Electricity-Eating Bacteria Are Real and More Common Than We Thought

In the extreme world of bacteria, stunts such as living in hot springs or without oxygen are, like, totally unimpressive. But then there are bacteria that live off electricity, feeding directly on naked electrons. Even more surprisingly, scientists are finding that these bacteria are not even that rare. » 7/17/14 7:47pm 7/17/14 7:47pm

The SpaceX Launch Is Sending Dinosaur Microbes to the Space Station

The SpaceX Dragon capsule that just left Earth for the International Space Station is carrying many an important item: a new laser communication system, coffee (which they just ran out of!), a planter for fresh produce, and billions and billions of microbes swabbed from dinosaur bones, sneakers, and spacecraft clean… » 4/18/14 4:45pm 4/18/14 4:45pm

Scientists Create Diode Propulsion Engine for Bloodstream-Swimming…

Science fiction edges ever closer to reality as researchers at NC State University devise a form of propulsion that can accelerate microbots through the human bloodstream. The challenge: not only finding a way to create this engine on such a tiny scale, but to provide power to it. The solution? Diode propulsion, using… » 3/15/07 1:37pm 3/15/07 1:37pm
