A newly identified class of RNA molecules has been discovered in bacteria living inside the human body. These circular genetic structures, termed obelisks, differ from known viruses and bacteria and ...

A new study shows that protein sequences associated with microbial communities in the human gut have uniquely low stoichiometric water content and undergo counterintuitive chemical shifts toward ...

Biologists mapping the human microbiome expected to find new bacteria and viruses, not entities that slip through every ...

Amyloids are perhaps best known as a key driver of Alzheimer’s disease. The amorphous proteins, found throughout the human body, stick to nerve cells like plaque, choking off their function and ...

Pathogens can create sticky situations. When microbes invade the body to cause an infection, often one of their first lines ...

How well bacteria move and sense their environment directly affects their success in surviving and spreading. About half of known bacteria species use a flagella to move — a rotating appendage that ...
