The bacteria in a mother's breast milk are important because it helps develop a baby's gut. Research shows this bacteria are different depending on where mothers live and what they eat.
New research shows viruses can effectively turn bacteria into animal-like cells.
Long viewed simply as 'germs,' the hidden half of nature turns out to be crucial to the health of people and plants.
The answer – fewer than are in a banana – has implications for the study of human health and raises questions about what generates complexity anyway.
For most of us, the form of stool we excrete can vary widely depending, in part, on what we've been doing.
The make-up of our gut is constantly changing and affects everything from our immune system and digestion, to our brain function.
Links have been made between the community of bacteria in your gut and depression, pain, stress and sleep. So what does the science say?
Bacteria are single-celled organisms but you'd be fooled to think they weren't also hugely complex.
Resistant bacteria enter our aging sewer infrastructure and may eventually end up in the environment through sewage spills.
Anyone for a 2,512-day-old burger?
Just like humans, corals live with myriad microscopic organisms. We are just starting to understand this unseen world.
How slow diagnosis of bacterial infections is exacerbating our antibiotics problem.
What started with a study of diseases transmitted by mosquitos, could end with a new way of treating cancer.
Bacteria can produce their own 'buildings' so scientists are genetically engineering them to build ours.
Need a tiny amount of energy? These microorganisms can help.
Scientists are working on a new method to cure cancer and have shown they can genetically program certain bacteria to invade the tumour cells of cancerous mice.
New research shows how adding memory to bacterial circuits could help us harness their computing power.
Genetic analysis shows that marine bacteria broke down much of the oil from the 2010 Deepwater Horizon spill. These findings could lead to more effective cleanups after future spills.
Doctors know that inappropriate prescribing can lead to antibiotic resistance. So why do they keep doing it?
Antibiotic resistance happens when bacteria change in a way that prevents the antibiotic from working in its normal manner. There are several ways in which this can happen.
