And the Hello and welcome to the naked scientist with me Chris Smith and with Cat Arnie.

What's a hundred times stronger than steel, transparent, and a football field-sized sheet of it

would weigh less than a gram. Stay tuned to discover the identity of this marvelous material that's apparently destined to

change the world we live in. Plus we go behind the headlines from the world of

science and technology to hear how scientists have discovered a trigger for

organ regeneration, how the first complex life Scientists have

pupils shaped like a trigger for organ regeneration,

how the first complex life on earth reproduced itself, and why do cats have pupils shaped like a vertical slit?

First this week researchers are saying they're on the brink of being able to

kick-start the regrowth of hair follicles and even other bodily organs.

Scientists have discovered a trigger in the form of short pieces of genetic material called

double stranded RNA, which switches on an immune pathway, inducing stem cells to rebuild

organs just like they would do in a developing baby.

Done in the skin, it could help victims of severe burns.

Louise Garza made the discovery at Johns Hopkins University in the US.

When I was a resident studying medicine, at Johns Hopkins University in the US.

When I was a resident studying medicine,

all of my teachers taught me that it was impossible to grow a new hair follicle

if you destroy the entire thing in an adult.

And yet, other people before us and we in this paper show that you

indeed can do that and so it does create hope that in the same way that I was
