TEENAGERS from an Oxford school have been commended for their film about an unsung hero of science.

Daniel Treuherz and Toby Saunders, both sixth formers at The Cherwell School, won second place as well as the audience choice award in a Hertford College contest.

The Oxford college launched the Unsung Heroes of Science competition in March, asking teenagers around the country to make a short video about a lesser-known scientist.

Cherwell's team dedicated theirs to the astronomer Caroline Herschel, who discovered several comets.

Competition judge Professor Alison Woollard said: "I was astounded by this brilliant video from two truly inspiring scientists-of-tomorrow.

"The world needs people and stories like this to keep going."

The challenge was open to pupils aged 16-18 across the UK.

The winners, who made a film about physician, surgeon and chemist Al-Zahrawi, will be invited to shadow newsreader and Hertford alumnus Krishnan Guru-Murthy at Channel 4 News.
