A fossil analysis suggests that the yunnanozoan, a wormlike fish that flourished around 520 million years ago, sported structures that were the precursors of the head and jaws of modern vertebrates.

More than 100 grants previously approved for applicants in Britain have been scrapped amid a continuing dispute over the UK’s refusal to fully implement trade arrangements made when the country left the European Union.

The shift is likely to add to an ongoing shortage of primates used in labs, which could slow progress in future COVID-19 vaccine development and other areas.

A new study using fairly complete genetic datasets of two phyla of small suspension feeders (Ectoprocta and Entoprocta) reopens the debate on the phylogenetic relationships between them and other animals.

A peptide found in bull ant venom closely resembles a hormone of its primary predator, triggering hypersensitivity and making subsequent bites even more painful than the ones that came before.

Scientists found that combining the notoriously flimsy anticancer protein p53 with a domain from a spider silk protein resulted in a more stable hybrid that’s more potent and easier for cells to synthesize.

Putting on a mask to protect oneself and others against disease is nothing new, nor is resistance to mask-wearing, but mask designs have changed considerably from their first iterations.

A study traces the effects of a mite outbreak from the earth to the heavens.

DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.

Too often, studies that aim to develop new treatments for patients fail to adequately cite and build upon research that preceded them.

The fish use their stomach to swell up to three times their size. Is this why they can’t use the organ to digest proteins?

The device can chill nerves as small as a few millimeters across, but more testing and modifications are necessary before it could relieve pain in humans.
