I have you loud and clear.

Hello.

Hello.

Welcome.

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

This week, when the worst happens at nuclear power plants, how do we clean up the mess?

We meet the scientists who are trying to use nature to neutralize

contamination. Plus a new way to target the spread of cancer, a slug-inspired

surgical glue, and the science behind bicycles. I'm Georgia Mills and this is the Naked Scientists. I'm Georgia Mills and this is the Naked Scientists.

First up a look at the top science headlines and there's been some promising research regarding

cancer this week.

The main cause of death for cancer sufferers isn't actually the original tumor.

Instead it's caused when cells from the tumor break off and spread around the body. This process, known as metastasis, makes cancer much harder to treat.

If you could pinpoint this process in the body with a kind of biological flag,

you could then gear treatment towards the tumors without damaging the rest of the body.

This sounds simple enough but has proven almost impossible as different tumors behave in such different

ways.

But now a team at the University of California Irvine

may have found such a flag which in mice at least allowed for a targeted attack on

multiple tumors at once. I spoke to Dr. Justin Alford, Senior Science Information Officer

at Cancer Research UK, who wasn't involved in the study about the research.
