Bacteria

Sequencing mammoth DNA has already helped scientists map out how these Ice Age giants evolved, migrated, and survived. But there's a hidden layer of history still waiting to be decoded – the microbes that lived inside them.

For the first time, scientists have identified 27 bacteria and fungi in our mouth that contribute to pancreatic cancer. Collectively, carrying all of these “bad” microbes increases cancer risk by 250% – 3.5 times higher than in the general population.

One of the problems with microplastics lies in the fact that the plastic particles can be so small, we don't even know they're present in water in the first place. A new type of engineered bacteria could help, by causing the particles to glow green.

A mysterious marine epidemic has killed billions of sea stars from North America’s Pacific coast. After more than a decade of unanswered questions, scientists have finally traced the disaster to a single bacterial species.

What we eat, what drugs we take, and even the timing or combination of treatments could influence how bacteria respond to antibiotics. A food ingredient like caffeine or a second medication might tip the balance, making antibiotics less effective.

A new study published in Nature Microbiology has reported a naturally occurring family of bacterial species in the human gut that can absorb and break down toxic, long-lasting "forever chemicals" and carry them out as waste through feces.

Humans have been getting infected by ancient bacteria and viruses for at least 37,000 years. Now, for the first time, pathogen DNA has uncovered a pivotal disease "turning point" that happened 6,500 years ago, which would forever change our lives.

Globally, stomach cancer is on the rise in young people, but new research shows that three-quarters of future cases could be prevented by screening for and treating a common bacterial infection: Helicobacter pylori.

Here's a rather novel way to keep trash out of landfills: engineering biologists have developed a way to turn common plastic bottles into the popular painkiller paracetamol. All it takes is a bit of bacteria and time to ferment the treated waste.

More than a third of large animals that feast on dead animals are struggling to survive, and a new report from scientists warns that their downfall could present a serious risk to human life, with an uptick in zoonotic disease spread as a result.

A small daily dose of kombucha made from black tea has been shown to meaningfully reshape the gut microbiome in adults – particularly those with obesity – without any dietary changes. It also reveals a lot about the importance of micro-biodiversity.

A new study from scientists at Michigan State University sheds light on a recently discovered microbe and its potential for scavenging pollutants in deep soil. Further work could lead to novel solutions in providing clean drinking water worldwide.
