Remains at Crenshaw site are local, ancestors of Caddo, study finds

A new study by University of Arkansas researchers determines that hundreds of human skulls and mandibles at the Crenshaw site are local ancestors of the Caddo Nation. The findings use a novel dating technique to test lead and strontium isotopes in human teeth, revealing a multiregional pattern indicative of local ancestry.

World’s first transgenic ants reveal how colonies respond to an alarm

Researchers developed transgenic ants with fluorescent neurons that flashed green in response to odorants, allowing them to study the ant olfactory system. Contrary to previous findings, they discovered that only a few specific areas of the olfactory system responded to alarm pheromones, suggesting a more localized processing mechanism.
