PROGRAMME INFO
Thursday 21:00-21:30
Leading Edge brings you the latest news from the world of science. Geoff Watts celebrates discoveries as soon as they're being talked about - on the internet, in coffee rooms and bars; often before they're published in journals. And he gets to grips with not just the science, but with the controversies and conversation that surround it.

The study of snowflakes could help scientists make local alterations in the weather.

Grow your own climate

Could analysing the particles inside raindrops and snowflakes allow us to alter the weather?

Cindy Morris of the French Institute of Agronomy believes it just might.

Hair today, jail tomorrow

Geoff speaks to researchers at the University of Utah who’ve found that the chemical make up of your hair can show where you’ve been.

Their work could have important implications in the field of forensics.

Space junk

Will space travel ever be safe?

Marcus Chown ponders the real and increasing threat of space junk.

The Mary Rose

Raised from the seabed nearly thirty years ago, Henry VIII's favourite ship is a remarkable record of Tudor naval life.

But preserving its artefacts needs the latest science, as Roland Pease reports.

Microscopic engineering

Geoff visits scientists at Harvard University who’ve been working at the molecular and cellular level to develop “biohybrids”.

Among other things, these combinations of living and non-living tissue could be used to patch a hole in the heart or test new medicines.
