Billions of years ago, the Great Oxygenation Event wiped out most life on Earth at the time. This ramped up about 2.5 billion years ago, but now scientists have discovered signs of the oldest known “oxygen oasis” in South Africa, showing that the process started almost half a billion years earlier.

Scientists may eventually be able to biologically engineer unique artificial lifeforms from scratch. A new study from Princeton has brought that future a step closer, by confirming that an artificial protein the team developed functions as an enzyme in living bacteria.

Crunching massive amounts of data, involving billions of measurements, has offered up a detailed picture of the changes a human body undergoes during periods of weight gain, including affecting a person's microbiome and immune and cardiovascular systems.

A UK study has found that regular surfers were three times more likely to have an antibiotic resistant strain of E. coli bacteria in their gut than non-surfers, suggesting surfers are more likely to be at risk from these microorganisms.

Imagine recruiting a strain of gut bacteria to help target and kill cancer cells in your colon? A team from Singapore is doing exactly that - genetically modifying a type of gut bacteria so it locks onto colorectal cancer cells and turns a substance found in broccoli into a cancer-killing toxin

There's a steady flow of research connecting our gut microbiome to different illnesses or diseases, but often the mechanisms behind these connections are unclear. A new study reveals one potential way good gut bacteria can control our gene activity and potentially help prevent colorectal cancer

An innovative ingestible capsule, designed to measure gases inside the gut, has just passed phase one human trials. The swallowable sensor could reframe how gastrointestinal disorders are diagnosed as well as offering a new insight into the activity of crucial bacteria in our gut microbiome.

To find out where a submarine is, you send out a sonar signal which that sub reflects back. It may some day be similarly possible to locate therapeutic bacteria within a patient's body, as scientists have created the first bacterial cells that are capable of reflecting sound waves.

Bacteria are hardy, but even they have their limits. One of those was previously thought to be polar ice, but a new study has now observed bacteria living in those conditions. That discovery has implications for our understanding of Earth's past climate, as well as life elsewhere in the universe.

A new study from a team at the University of Massachusetts Amherst has found that some non-toxic food preservatives, added to food for antimicrobial properties, could be unexpectedly and adversely interacting with out gut microbiome.
