Placing bacteria on a conducting plastic electrode does more than deliver electrical current; it flips genetic switches that rewire their internal metabolism to pump out useful chemicals.
Sex chromosomes alter cell metabolism and disease risk entirely on their own, operating independently of circulating sex hormones like oestrogen or testosterone.
Scientists edited the same nine unwanted genes in hamster cells using two distinct timelines. Editing several genes at once caused far less cell damage and gene disruption than snipping them one by one.
A common gut bacterium eats host mucus when other food runs out, but its own protective sugar shell can physically get in the way. Researchers also found that while the microbe switches on dozens of digestive enzymes, most are backup workers that can be lost without slowing it down.
Using long-read sequencing on human blood cells exposed to X-rays, researchers detected changes in alternative RNA messages that standard gene-level counts miss entirely.
A review outlines how targeted gene editing could help major sugar crops withstand heat and drought, though almost all proposed fixes still await tests in living plants.
Genetic analysis of Jonathan, a 194-year-old Aldabra giant tortoise, shows that key switches controlling his cellular powerhouses remain remarkably tidy despite his extreme age.
A computer modelling study shows that placing electrical charges on hollow organic cages creates oriented electric fields that speed up chemical reactions up to 100-fold.
Ancient genomes from Colombia show that local groups began eating maize long before outside migrants arrived and replaced them.
Researchers found that immune cells detect a compound concentrated in muscle tissue, which explains how red meat and muscle damage can trigger inflammation.
