Hello, and this week scientists.

And with Cat Arnie Hella Cat.

Hello, and this week scientists have grown a new functioning liver from stem cells.

We'll hear how it works, how cancers evolve to become resistant to drugs, and what will the

last life forms on earth look like?

I'm betting cockroaches.

We're bringing you the latest from the UK's National Astronomy Meeting in St Andrews.

First up let's take a look at this week's top science new stories

and I've got a story about scientists in

Japan managing to do a world first and to re-grow a new liver in a dish using stem

cells this is tachanori tachabe from the Yokohama City University.

It's a paper in nature this week. And what he and his colleagues have done is to go to what are called

IPS or induced pluripotent stem cells.

These are cells that were initially made by reprogramming skin cells to make them into stem cells.

They then grow these cells in a dish alongside some what

are called mezankymal stem cells which are another population of stem cells you

find in the developing embryo and some endothelial cells from the umbilical
