Science Cafe, Adam Walton

Series 5: Prog 05: 26/04/09

Adam Walton presents your weekly guide to science.

This week Adam Walton hears how biologists in Bangor are trying to tackle illegal fishing. There's news of the UKs new super radio telescope. We visit Techniquest in Wrexham to hear about the colour of stars, and we discuss the decline in numbers of bees and new funding for scientists to tackle the problem.

Fish markers

The problem of illegal fishing across the World is now being tackled by a major new project being spearheaded by biologists at Bangor University. New tools including a "genetic birth certificate" and analysing the ear bones of fish are being developed to offer rigorous proof of origin and species of fish in cases of illegal fishing. Adam Walton talks to Professor Gary Carvalho who is heading the team at Bangor.

eMERLIN magic

A new upgrade to the MERLIN telescopic array in the North of England has recently been swtiched on, and offers astronomers in the UK and across the World a chance to have access to much greater clarity in their observations of the Universe. We hear from Dr Tim O'Brien of Jodrell Bank, where the new "eMERLIN" is based, and also from Derek Ward-Thompson from the Cardif School of Physics and Astronomy, who hopes to use the power of the eMERLIN telescope array to find new planets.

Red glow in the sky

Adam visits Techniquest at Glyndwr University in Wrexham where John Griffith explains the colours of stars, and tries an experiment to illustrate how the heat generated by an object affects its colour.

Bee concern

Funding of £10 million has been announced for scientists to tackle the growing concern about the declining numbers of bees. Numerous theories have been put forward as to why bee numbers are falling, and joining us on the programme is the UKs only Professor of Apiculture, Francis Ratnieks from the Universtiy of Sussex and Dinah Sweet of the Welsh Beekeepers Association, who has kept bees for over 30 years.
