By studying tissues from deceased people, a team found that women have more rhythmical gene expression and that this molecular rhythmicity decreases with age.
A reference sequence for this emerging model organism will facilitate research on type 2 diabetes and the health effects of circadian rhythm disruption.
Before their own central clocks develop, the brains of fetal rats detect their mother’s metabolic cycle to help regulate the expression of certain genes.
Disturbing circadian rhythms in organoids and mice increases intestinal tumor growth, findings that may explain a recent rise in colon cancer among young adults, the researchers behind the work say.

More cancer cells are shed from primary tumors when individuals are asleep than when they’re awake, according to observations in mouse models and a small cohort of breast cancer patients.
The microbiota helps align a mouse’s innate immune system with its feeding patterns, prepping the animal to fend off infection when it’s most likely to be eating.
A study of 19 postmenopausal women found that eating a bar of chocolate in the morning affected their bodies differently than eating it at night, but neither led to weight gain.
Two studies show that Plasmodium—the genus of protozoans that cause malaria—have an internal sense of time that synchronizes with their host’s circadian rhythms and allows the parasites to collectively attack blood cells.
As global temperatures rise and winters shorten, caterpillars of the corn borer moth are emerging earlier in parts of the US thanks to changes in two genes, researchers find.
