The Naked Scientists Podcast · Malaria drug breakthrough, and space radiation vests · 14 Aug 2026 podcast

So how are you able to soak them up?

And to what extent can you soak up the radiation?

How much does the dose drop by?

Oren Milstein, who's the CEO at Stemrad, and if you want to see for yourself what Oran's new vest looked like, he has sent us a picture that accompanies the transcript of his interview.

You can have a look at NakedScientist.com, just click on the podcast link, you'll see this show listed there and the interviews that are in it, including this one.

Tooth sensitivity affects around half of UK adults, causing sharp pain that can put people off cold drinks, ice cream, or even brushing properly.

Most sensitive toothpaste can only mask the symptoms either by numbing the nerves in our teeth or slowly blocking the microscopic tubules that get exposed in worn down teeth, and that takes days of repeated use.

Now an NHS surgeon has taken a different approach, borrowing a material from Aerospace and Bone Graft Science.

Aerogel is an ultralight porous solid used occasionally by NASA and nicknamed Frozen Smoke.

NASA use it to capture micrometeors in space.

Upon contact with saliva, the new material releases sequestered calcium and phosphorus ions to seal up the tube.

Within the teeth within just minutes to rebuild a protective mineral layer on the tooth and reduce the sensitivity.

It's the first newly patented approach to tooth sensitivity in almost three decades.

This deals with the problem of sensitive teeth, doesn't it?

So what is that and who's got it?

And if you look at the tooth, what's actually going on to produce that unpleasant effect?

And what is it because what's in the tubules gets cold or hot and that transmits that to the interior nerve in the tooth?

There's a lot of calcium and phosphate already in toothpaste.

If you look at the back of the tube, you know this as a Max Fax person.

It's loaded with the stuff.
