Mammoth Biosciences has secured an emergency authorization from the FDA for its high-throughput COVID-19 test, which is powered by CRISPR gene-editing enzymes.

How much should you trust the results of a rapid antigen test? That's a question many people are asking these days amid recent research and anecdotes suggesting these tests may be less sensitive to omicron. Researchers are working fast to figure out what's going on and how to improve the tests. Source: NPR.

NIBIB-funded researchers have found a way to model the human neuromuscular junction by growing these synapses in a lab, which could accelerate novel treatments for neuromuscular diseases.

With questions swirling about how well rapid COVID-19 tests work when it comes to detecting the omicron variant, leading scientists are now reassuring the public that they do work, and have a valuable role to play in the ongoing pandemic. Read more at ABC news online. ABC news online.

As the coronavirus spawns a record-breaking wave of infections, new research suggests that rapid tests widely used to identify potential covid-19 cases might be less effective at identifying illness caused by the swiftly spreading omicron variant. Read more at the Washington Post. Washington Post.

The US FDA said Tuesday that quick antigen tests people take at home may be less sensitive to picking up the Omicron variant of the coronavirus, but health officials say they're still a useful tool. Read more at CNN health. CNN health

The U.S. drug regulator has granted emergency use authorization to German health technology company Siemens Healthineers' (SHLG.DE) at-home COVID-19 tests, a move that will boost availability of tests pressured by rising infection cases. Read more at Reuters. Reuters.

NIH RADx Tech Independent Test Assessment Program provides support for FDA authorization of two rapid at-home COVID-19 tests.

A new study shows how the brown anole lizard solves one of nature's most complex problems -- breathing -- with ultimate simplicity. Whereas human lungs develop over months and years into baroque tree-like structures, the anole lung develops in just a few days into crude lobes covered with bulbous protuberances. These gourd-like structures, while far less refined, allow the lizard to exchange oxygen for waste gases just as human lungs do. And because they grow quickly by leveraging simple mechanical processes, anole lungs provide new inspiration for engineers designing advanced biotechnologies.
