I have you loud and clear.

Hello.

Hello.

Welcome.

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

Hello, this is the Naked Scientists,

the show that brings you the latest breakthroughs in science and technology. I'm Katie

Hala and I'm Adam Murphy. This week tick-talk we are talking body clock science

whether it's eating, sleeping or coming down with something we're taking a look at the

biology of our daily rhythms.

Plus in the news doctors begin testing gene editing to treat cancer and what have

honey bees and love hearts got in. We'll be finding out.

The Naked Scientists Podcast is powered by UKfast.co.uk. In a world first in humans, scientists in the US have used the gene editing tool

CRISPR to treat patients with cancer.

In a proof of concept study, the team began by harvesting immune T cells from three patients

with advanced tumors.

They then edited the T- cells genes to reprogram the receptor

that the T cells use to recognize hostile targets so that they would then regard

the patient's cancer cells as foreign and destroy them.

A gene that normally puts the brakes on cell growth

was also disabled so the T cells should be able to grow and expand their numbers in the body

to keep the cancer under control in the long term.
