Fermented foods sustain both microbiomes and cultural heritage

From kimchi to kombucha and sauerkraut to sourdough, many traditional food staples across cultures make use of fermentation. And these variations are reflected in your microbiome.

Infections after surgery are more likely due to bacteria already on your skin than from microbes in the hospital − new research

Most infection prevention guidelines center on the hospital environment rather than the patient. But the source of antibiotic-resistant microbes is often from the patient’s own body.

Thin, bacteria-coated fibers could lead to self-healing concrete that fills in its own cracks

Your skin heals from cuts and scrapes on its own − what if concrete could do that too?

Bacteria can develop resistance to drugs they haven’t encountered before − scientists figured this out decades ago in a classic experiment

The Nobel Prize-winning Luria−Delbrück experiment showed that random mutations in bacteria can allow them to develop resistance by chance.

Sugary handshakes are how cells talk to each other − understanding these name tags can clarify how the immune system works

Sugar molecules called glycans cover the surface of all cells, acting as ID cards that broadcast what they are to the rest of the body.

Vampire viruses prey on other viruses to replicate themselves − and may hold the key to new antiviral therapies

Researchers discovered a satellite virus latching onto the neck of another virus called MindFlayer. Studying the viral arms race between similar viruses could lead to new ways to fight infections.

Your microbes live on after you die − a microbiologist explains how your necrobiome recycles your body to nourish new life

With the help of the microbes that once played an essential role in keeping you alive, the building blocks of your body go on to become a part of other living things.

Flesh-eating bacteria infections are on the rise in the US − a microbiologist explains how to protect yourself

Warmer ocean waters are fueling the spread of the bacteria Vibrio vulnificus. Infections can lead to a rare but fatal condition called necrotizing fasciitis.

_E. coli_ is one of the most widely studied organisms – and that may be a problem for both science and medicine

Researchers uncovered the foundations of biology by using E. coli as a model organism. But over-reliance on this microbe can lead to knowledge blind spots with implications for antibiotic resistance.
