136 long-clawed shrew skulls from Hokkaido showed the classic winter flattening of the braincase, and across the same series the snout enlarged in winter and shrank again in spring

2+ day, 3+ hour ago   (595+ words) A museum series of Sorex unguiculatus from Tomakomai confirms Dehnel's winter braincase shrink in an Asian shrew, and adds a reverse pattern in the snout that the authors did not find in the jaw. By Natural History · Edited by Chris…...

A cattle parasite changes the smell of the animals it infects, and tsetse flies carrying it showed raised activity in several odour-receptor genes alongside reduced activity in five light-sensing genes — traps baited with a three-phenol blend caught twice the share of infected flies that unbaited traps did

4+ day, 11+ hour ago   (628+ words) The gene work was done on wild flies caught in a Kenyan reserve, because this species is so hard to infect in a laboratory. By Natural History · Edited by Christy Jeremia Published September 10, 2026 · How we edit The behavioural results are…...

Researchers invited 11 people to cuddle two Holstein steers at a New York sanctuary, and the animals developed a striking preference — they were far more engaged with the women than the men

Humpback whales can sing for up to 16 hours without stopping, and scientists have found their songs are synchronized with every dive — different themes line up with the descent, the deep-water phase and the climb back to the surface

There is no queen and no hive behind Xylocopa caerulea: each female excavates her own wood tunnel, packs it with bee bread of pollen and nectar, lays an egg on the store and seals the cell before starting the next

1+ week, 1+ day ago   (343+ words) A blue carpenter bee working a tropical garden looks like a scrap of sky that got loose, and the temptation is to imagine a hive somewhere behind her — a colony, a queen, a comb. By Lab Report · Edited by Justin…...

An unknown human lineage interbred with our ancestors in Africa more than 50,000 years ago — and although scientists still don't know who these humans were, traces of their DNA survive in every modern population studied.

1+ week, 6+ day ago   (1147+ words) A new genomic method detected roughly 0.49% to 1.1% ancestry from an unidentified human population across five sampled groups. The signal points to mixing in Africa before the main out-of-Africa expansion, but it has not been matched to a fossil species. By…...

Western disgust at eating insects may have roots deeper than culture — dental plaque from 745 ancient humans found Europeans rarely ate them, while genetic evidence shows reduced ability to digest their exoskeletons persisted for at least 9,000 years.

2+ week, 16+ hour ago   (1222+ words) Sparse insect DNA in ancient northern Eurasian dental calculus and 9,000-year-old chitinase patterns point to a deep ecological history without identifying a gene for disgust.

Scientists once thought zebra stripes might help confuse predators, but when researchers dressed horses in zebra-striped coats, biting flies repeatedly failed to land — adding to evidence that the famous pattern evolved to thwart insects, not lions

Emotional tears may have evolved not merely to express sadness, but to change the behaviour of the people around us — a distress signal originating in infancy that humans carried into adult social life to recruit attention, care and protection.

Why 34 of 38 crickets in a dark glass tube walked away from a synthetic copy of one terpene found in a bat's snout secretions, and why the researchers still cannot say how a cricket tells a bat from a leaf
