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

4 Ways Tiny Microbes Changed Life on Earth Forever

This is the microbes' world—we just live in it. Throughout the history of Earth, microbes have radically reshaped life on the planet, from creating the very air we breath to wiping out almost all life on Earth. Don't underestimate the power of tiny, tiny microbes populating the Earth trillions of times over. » 4/07/14 12:00pm 4/07/14 12:00pm

How NASA Prevents a Space Plague Outbreak

In the early days of space exploration, NASA basically made up procedure on the fly. With little knowledge of the world outside our atmosphere, agency physicians worried what humans might encounter out there. Maybe John Glenn would go Space Blind. Maybe the Apollo 11 crew would track an Andromeda Strain through the… » 9/25/12 1:00pm 9/25/12 1:00pm

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
