I have you loud and clear.

Hello.

Hello.

Welcome.

Science.

And that is the same physics, medicine, nature, or space,, the brain, life, the universe.

Hello, this week from skin care to going under the knife, we're lifting the lid on the science of looking good.

Plus in the news, a DNA repair kit. lifting the lid on the science of looking good.

Plus in the news, a DNA repair kit that can fix genetic diseases and a UK project

launches to clean up 7,000 tons of space junk.

I'm Katie Haleer. And I'm Chris Smith and this is the Naked Scientist.

UK. UK. Fast.

Go dot UK. First this week, scientists in Cambridge have developed a system to fix a class of devastating genetic

diseases called mitochondrial enzyme defects.

Charlie Gard, a little boy who became a high profile case at Great Orman Street Hospital, who sadly died last year had one of these conditions.

They occur when structures called mitochondria, which supply our cells with energy, don't function properly.

This happens because some of the mitochondria, which

contain their own small piece of DNA, carry genetic changes or mutations that prevent

them from working properly. But now there might be a way to fix the problem.

Piam damage from the Medical Research Council's Laboratory of Molecular Biology has developed

a gene editing system that knocks out selectively the defective mitochondria so they're replaced by healthy
