Plunging down to a depth of about 11,000 m (36,000 ft), the Mariana Trench is the deepest part of the ocean, so it's no surprise that we don't really know what's down there. New species and strange sounds have turned up recently, and now researchers have discovered a new group of oil-eating bacteria...

Though it is not the most abundant greenhouse gas, methane is certainly the most potent when it comes to trapping heat within the atmosphere. So while it be far lower in concentration than CO2, there is considerable interest in eating away at its presence. Scientists in Europe have made an exciting breakthrough in this area, isolating a previously unknown bacterium that appears to have a r
Knowing the make up the microbial community on the International Space Station (ISS) would be of huge use to space agencies trying to safeguard the wellbeing of their astronauts. This has been a focus of NASA's for a while, and its scientists have just put the finishing touches on what they say is the first comprehensive catalog of all the bacteria and fungi inside the ISS, describing a ba
Bacteria are fast evolving resistance to antibiotics, which is fast-tracking us to a future where our best drugs no longer work and simple infections become life-threatening once again. While new antibiotics are in the works, the bugs will eventually develop resistances to those too, so a longer term strategy might be to prevent them from evolving in the first place. A new study has found
Probiotics, delivered in pills or foods like yoghurt, have long been held up as a force for good in the body, but there may be a bit of a gray area between good and bad bacteria. A mouse study conducted at Washington University in St. Louis has now found that probiotics can evolve in the gut, becoming less effective or even turning against the host...

The fact that bacteria can share genes with each other is fascinating and a little alarming – after all, that's how they're developing resistance to antibiotics so quickly. It's easy to assume that the bugs need to be in close proximity to teach each other, but unfortunately that might not be the case. A new genetic study of bacteria from around the world has found that isolated population
Humans weren't built for space travel – the harsh environment messes with our vision, circulation, muscles and bones, and increases our risk of cancer and diabetes. The immune system also takes a beating, leaving us more vulnerable to infection. Astronauts have now tested a new antimicrobial coating on board the International Space Station (ISS), and found it kept the space-faring bugs at
Hospital-acquired infections are a serious problem, and the most common type of such infections occurs when catheters are inserted into blood vessels. A new coating, however, shows promise for killing bacteria at insertion sites, keeping them from establishing biofilm colonies on the catheters...

The smallest creatures can have some of the biggest impacts on the planet. You can get a sense of how healthy a given environment is by taking a census of the health and types of microorganisms that call it home. Now researchers at Berkeley Lab have developed a new way to get a larger snapshot of what's going on, by looking specifically at the genes bacteria pass around to help each other
An international team of scientists has discovered bacteria can enter a previously unknown zombie-like state, in between dormancy and activity, allowing it to survive for extended periods of time when its environment is starved of nutrients...
