This week on Science in Action with Sue Broom…… Ivory DNA Poachers are again threatening the survival of the African elephant, flouting the 1989 export ban which initially reduced the trade in elephant tusks. Now scientists are aiming to control poaching
using a new genetic technique which traces the ivory back to the
elephant’s native land.
Professor Sam Wasser at the University of Washington explains.
Cloning We mark the 10th anniversary of the scientific paper which announced Dolly the sheep.
Green muscle A new weapon against desert locusts has been developed in the form of a naturally occurring fungus. It’s hoped that Green Muscle will minimise the environmental damage caused by chemical sprays. Locust specialist Keith Cressman tells Sue how it works. Proton beam therapy Particle accelerators are more than just the means to probe the frontiers of physics. They are also used by doctors in the fight against cancer. Their beams of protons kill tumours of the eye, brain and prostate with great precision. Azi Khateri reports from the Clatterbridge Centre for Oncology in the UK.
Squid capture Australian marine biologist Mark Norman of Museum Victoria explains why he’s not so happy about the world-breaking capture of a Colossal squid in Antartica by New Zealand fisherman.
Hurricane research Flying aircraft into the eye of a hurricane may seem foolish, but researchers did just that during hurricanes Rita and Katrina. The findings are being used to predict the intensity of future hurricanes, something that has proved very difficult, as Robert Houze from the University of Washington explains.
