I have you loud and clear.

Hello.

Hello.

Science and that is the say physics, medicine, nature, or space, time, brain, life, the universe.

Hello, welcome to the Naked Scientists, the show where we bring you the latest breakthroughs in science and technology, me Adam Murphy and with Chris Smith.

This week we're looking at radioactivity from its uses in medicine to its uses in war.

Plus a sneak preview of a new film due out soon all about Radio Activity Pioneer Mary Curie.

Plus a new 90 minute test for coronavirus infection, how fast is the new coronavirus mutating

and evidence that humans are just like dogs, we eat much faster if there's someone else around.

The Naked Scientist Podcast is powered by UKfast.co.uk. dot UK. Test, test, test, the World Health Organization have said,

counseling the world on how it ought to be proceeding in trying to gain control of the coronavirus pandemic

But scaling up to offer tests to large numbers of people as well as making tests fast and agile seems to be proving very difficult.

Now researchers at the University of Cambridge and the company Diagnostics for the real world

have repurposed a rapid HIV test so it can detect coronavirus infections

in just 90 minutes. The system generates multiple copies of the genetic information for the

virus if it's present and then produces a visible pattern of three lines on a

readout as well as an electronic log of the results. I spoke to Dammy Collier who's been working on the new

system. This is a rapid diagnostic test for COVID-19. So it's

rapid in the sense that from taking the sample from the patients which is

usually a swab of the
