Your own stem cells could help deadly bacteria hide in your body - a discovery that could inspire new treatments for tuberculosis.
Over 2 billion people are infected with TB. Typically, the bacteria lie latent inside balls of immune cells, or granulomas, in the lungs. Carriers get sick when t... Read More
A team of Nasa-supported researchers has discovered a microbe in Mono Lake, California, that lives in an environment high in salinity, alkalinity and arsenic – which would be toxic to most organisms. Studies of species in extreme environments help astrobiologists define the physical boundaries o... Read More
Nonchemical treatment systems are touted as environmentally conscious stand-ins for such chemicals as chlorine when it comes to cleaning the water-based air-conditioning systems found in many large buildings.

A new study has revealed that there are greater similarities between the DNA repair systems of bacteria and humans than previously thought.
The University of Bristol researchers have discovered how a network of repair proteins enables bacteria to prioritise the repair of the most heavily used... Read More
Last week, amid much fanfare, scientists reported they had found an organism that — unlike all previously observed life on Earth — was able to do without phosphorus and use the normally deadly element arsenic in its place.
This week, skeptical scientists expressed serious concerns about the d... Read More
