Scientists say they've found the world's oldest fossils, the remains of tiny creatures that lived 3.4 billion years ago in a pre-oxygen world.
There is more proof that all forms of life share certain characteristics with humans. This time it’s our preference for caffeine.
It could soon be possible to use bacteria to generate energy, following a discovery by scientists at the University of East Anglia.
Researchers at McMaster University have made an interesting discovery about those “gut feelings” we sometimes have. It’s a big discovery linked to little organisms.
A theoretical physicist has presented research that shows bacteria might transmit electromagnetic signals to produce species-specific wavelengths.
Scientists have been studying how spaceflight makes bacteria more virulent, in work that could have implications for the health of the Earthbound as well as astronauts.
A NASA scientist says he's discovered alien life, in the form of microscopic fossils, embedded in meteorites.
Bacteria usually attack you with toxins designed to hijack or even kill host cells. To avoid self-destruction, bacteria possess a way of protecting themselves from their own toxins.
A team at the University of California has successfuly implanted E coli bacteria with the key molecular circuitry to act as computers.
The good news: scientists have discovered a completely new type of bacterium that could help with the disposal of old ships and oil rigs. The bad news: it's eating the Titanic.
Oh dear, oh dear. A week or two ago, I found myself on a city street listening to a very cross man on a soap-box explaining that evolutionary theory couldn't possibly be correct, as he remembered his grandfather and his grandfather wasn't a monkey.
Thanks to the abundance of medical fear mongering in America, people are obsessed with killing microorganisms. Antimicrobial compounds are the weapons of choice, but a biologist at Arizona State University is saying they are unsafe and don’t work.
Some bacteria grow electrical hair that lets them link up in big biological circuits, possibly communicating and sharing energy.
A new strain of bacteria has been found that could help clean up some of the nastiest pollutants in the massive Gulf oil spill.
Common bacteria found on spacecraft may be able to survive the harsh environs of Mars long enough to inadvertently contaminate Mars with terrestrial life.
Forensic scientists now have a new way to track criminals and terrorists - through the germs they leave behind.
