What if Your Mask Could Test You for COVID?

Harvard researchers have invented a mask that can test the wearer for COVID:

Researchers at Harvard University’s Wyss Institute for Biologically Inspired Engineering have figured out how to integrate a freeze-dried diagnostic Covid-19 test into a face mask. The test reacts with exhaled particles and gives a diagnosis in 90 minutes or less.

The tests and a tiny blister pack of water can be mounted on any mask. After the mask has been worn for at least 30 minutes, a person punctures the blister pack to release the water needed to rehydrate and run the reactions. The test result is indicated by one or two lines, similar to a pregnancy test

The masks will be affordable and could be useful for a lot more than COVID:

The Wyss team…expects the product to cost about $5. The technology can be targeted to identify other viruses and variants as well.

Any such masks would be subject to FDA approval. Another team at University of California, San Diego is working on a sticker that could be stuck to any mask to test the wearer. Those stickers could cost mere cents.

Incredible ingenuity!

An Outstanding Science Movie and Your Chance to Talk to a Nobel Prize Winner

I just finished watching the superb documentary Human Nature, which details the origins and applications of CRISPR gene editing. The filmmakers interview all the leading people in the field and produce a fascinating and highly accessible narrative.

I found particularly striking how one of the co-inventors of CRISPR, Jennifer Doudna, enjoyed being in an unknown field at first but also wondered whether the field was neglected because it was a dead end. It shows us what we can accomplish when we overcome our self-doubt!

You can see the movie and attend a talk tomorrow at 1pm EST with Nobel Laureate Jennifer Doudna here, both free of charge. It’s not often a person gets the chance to ask questions of a Nobel prize winner. I’ll be there!

P.S. If you’re interested in CRISPR, I recommend this book.)
