Molecules in larvae’s food determine whether honeybees are queens or workers
Plant microRNA plays a key role in determining whether a female honeybee develops into a queen or a sterile worker. The tiny molecules are present in bee bread, a […]

Gut microbes change seasonally in Tanzania’s Hadza people
The gut microbes of a tribe of hunter-gatherers in Tanzania change along with the seasons. Researchers collected stool samples from the Hadza and found that not only is their gut microbiome diverse, […]

Cloud bands like those around Neptune observed on brown dwarfs
Cloud bands similar to those around Neptune have been detected surrounding brown dwarfs, massive objects that aren’t quite planets and didn’t make the cut as stars. This is the first […]

CRISPR edits genes in pigs to make organs safer for transplants
Researchers have inactivated porcine endogenous retroviruses using CRISPR-Cas9, paving the way for potentially safer pig-to-human transplants. After 25 retroviruses were edited out of the pig DNA, the genetic material […]
