Ancient microbes appear to have used molybdenum as far back as 3.7 billion years ago, despite the metal being scarce in Earth’s early oceans. Scientists funded by NASA have found that organisms living on Earth more than 3 billion years ago were already using molybdenum, even though the metal was extremely rare in the environment […]

Scientific Reports, Published online: 22 August 2026; doi:10.1038/s41598-026-65638-7 Influence of defatted winged termite ( Macrotermes natalensis ) inclusion levels in diets on caeca bacterial community of Ross 308 broiler chickens

The Chagas disease parasite (Trypanosoma cruzi) undergoes a major transformation throughout its life cycle in order to infect humans and other mammals.

Scientists have linked a specific gut bacterium, Roseburia inulinivorans, to stronger muscles in both humans and mice. Older adults who carried it had 29% greater handgrip strength, while treated mice gained about 30% more grip strength and developed larger, more fast-twitch muscle fibers. The bacterium was also less common in older people. Researchers say it could eventually become a probiotic c…

A 2026 Mendelian-randomization study connected genetic proxies for certain gut bacteria with cognitive performance. The finding is a research clue, not evidence that a probiotic or diet can improve cognition.

NPR's David Folkenflik talks with Don Schaffner, a food microbiology specialist and distinguished professor at Rutgers University, about this summer's foodborne illnesses and recalls.

Purple non-sulfur bacteria (PNSB), a major subgroup of purple phototrophic bacteria (PPB), have emerged as a promising platform for integrating wastewater treatment with resource recovery through the simultaneous production of value-added products, including single-cell protein (SCP), polyhydroxyalkanoates (PHAs), hydrogen, lipids, pigments, and other biomass-derived compounds. Although substanti…

A new NASA-backed study has pinpointed why astronauts often experience constipation in space and how that might affect their health on long-haul missions to Mars and beyond.

Bacteria may build a memory of herbivore attack in the soil and coax new plants to attract wasps to rein in destructive pests.

Newly inserted lipopolysaccharide does not simply mix into the existing membrane. It forms persistent patches, whilst outer membrane vesicles remove older material. This process allows E. coli to adapt its surface even in the absence of growth and division.

Antibiotic resistance in humans and farm animals poses a major health challenge. A new study published in the journal 'Nature Communications' reveals that this problem does not stop at hospital doors or farm gates - indeed, antibiotic resistance genes (ARGs) can also be detected in wild animals.

Inside every cell, thousands of proteins must reach the right place at the right time. Helping coordinate this complex logistics network are centriolar satellites--tiny, membrane-less organelles that play important roles in protein trafficking, cell division, and the formation of cilia.
