There's romance in the air for this Valentine edition of Science Cafe. Adam learns more about a study to gauge if reading love poetry really can raise your temperature...

Feeling Coy?

Resarchers at Aberystwyth University have been using state-of-the-art Thermal Imaging Cameras to record the changes in the faces of volunteers reading love poems - including Andrew Marvell's His Coy Mistress. They hope to prove that there's not only a cerebral dimension to reading love poetry, but that it can also produce measurable physical effects.

Flutter, flutter

A Welsh scientist working at Rothamsted Reasearch Centre in Hertfordshire has discovered that insects use wind highways to travel at speeds of up to 60mph. Dr Jason Chapman and his team have been studying migrating butterflies and discovered that despite their fragile appearance, these tiny creatures have a inbuilt system to find these highways.

Red Alert

The numbers of Red squirrel in Wales continue to dwindle and this week a new conservation plan has been approved to save them from extinction. Liz Halliwell, a mammal ecologist with the Countryside Council for Wales, explains how scientist are helping to work on the issue.

Radiating

Fifty-nine years ago this week the first clinical trials of neutron capture, and early form of radiotherapy, were taking place in New York. Today, of course, radiation therapy is a recognised and often successfull treatment for cancer and a multitude of other illnesses. Two radiographers from the Velindre Cancer Treatment Centre in Cardiff join the programme to talk about how it works and advances made.
