Quentin Cooper reports on a four-month rat cull underway in South Georgia, the protective powers of olive oil and the Romantic Chemistry exhibition at the Royal Society.
Dr Dave Reay analyses the latest Energy Bill statement by the Energy Secretary.
An expedition of scientists, helicopter pilots, chefs and engineers embark on a four month mission to eradicate the brown rat from South Georgia. Professor Tony Martin, the team's leader, will be talking to Quentin about how his team will spread rat bait across 94,000 hectares of land.
Olive oil could be used to preserve ancient stone buildings, like York Minster. Synchrotron X-ray methods are used to understand the protective powers of olive oil for stone. Dr Karen Wilson will be joining Quentin on the line from Cardiff.
Also, Quentin talks to Professor Martyn Poliakoff about the new "Romantic Chemistry" exhibition at the Royal Society. The exhibition looks at the most unusual elements discovered by Fellows of the Society during the Romantic period (1780-1825).
