Rock-Eating Martian Microbes?
A recently published study of a 30-pound martian meteorite found in Antarctica suggests the presence of indigenous carbon-rich material, ancient water erosion, and a number of tiny structures that resemble the sort of features that we see rock-eating microbes leaving in basaltic glasses here on Earth.
Bacteria in space!
Where humans travel, bacteria will follow. If people are in space for any amount of time, bacteria are sure to thrive there so it’s good to know that there are already researchers looking at how the environment within spaceships affects bacterial populations.
Categorising bacteria in purple and pink
When confronted with a new bacteria there are a series of simple tests that can be carried out to give a rough idea of the properties of the bacteria you are dealing with.
Dawn attack: how plants anticipate pathogen infection
Like animals, plants are susceptible to infections from bacteria, viruses and fungi. While animals have a wide variety of immune cells and in some cases an interconnected immune system plants must rely on other methods to fight infection.
Swirling and whirling: the movement of spherical bacteria

On the Curious Motions of Syphilis and Lyme Disease Bacteria
The bacteria that cause syphilis and Lyme Disease have something extraordinary in common: they manage to propel themselves through their environment in spite of the fact their tails are located inside their bodies.
The SOS response: how bacteria deal with damaged DNA
DNA is important stuff. It’s present in all living organisms on the planet (or ‘almost all’ if you wish to remain friends with virologists) and contains the information required to produce and organise the proteins within a cell.
The FDAs Action on Agricultural Antibiotics is Overdue and Utterly Insufficient
Most of the meat on our dinner plates comes from cows and chickens treated with a battery of drugs that helped them grow quickly in dismal, cramped conditions that would otherwise make them sick.
The bacteria in breast milk
Bacteria are found in large numbers all over the human body where there is a channel to the outside world, for example in the gut, lungs, and surface of the skin.
