A spore is a bacterium's survival capsule: dried almost solid and wrapped in protein armor, with its chemical processes shut down. Bacteria enter this state of hibernation when environmental conditions are unfavorable. What's left is close to indestructible: It can survive boilin

Microbial cell factories that produce pharmaceutical ingredients and other useful compounds include both the bacterium Escherichia coli and yeast, the organism used to leaven bread and ferment alcohol. The two organisms turn genes on by different rules, so a production design bui

A new study suggests coffee may influence mood and brain function by changing the activity of microbes in the gut. Both caffeinated and decaf coffee were linked to lower stress, depression, and impulsivity, while also producing measurable changes in gut bacteria and metabolites.

Spaceflight may dramatically change the gut within weeks, causing bacteria to break down more protein as food moves more slowly through the intestines. The shift could help explain astronaut constipation and may have wider effects on health, making it an important concern for fut

Scientists resurrected antimicrobial peptides from mammals that lived millions of years ago and found that some were more potent against drug-resistant bacteria than modern human versions. These evolutionary relics could provide new clues for designing treatments as antibiotic re

A magnet-producing bacterium extended the average lifespan of C. elegans worms by more than 43% while helping protect their neurological and intestinal health. Researchers traced much of the effect to suppression of ferroptosis, a damaging form of cell death linked to iron buildu
