  • 00:17 - Climate change has affected crop yields

    In the last 30 years, corn and wheat crops have dropped by 3.8 and 5.5 per cent in response to climate change. This decrease in production has occurred in spite of technological advances, pest control measures and the use of fertilisers...

  • 02:53 - Box Clever: jellyfish use eyes to navigate

    At just one centimetre across, the box jellyfish makes a poor contender for being a paragon of intellect. But now new research has show that these tiny creatures can actually navigate by following the outlines of objects in the sky above them.

  • 06:13 - Antihydrogen trapping

    Researchers at CERN have managed to trap anti-hydrogen atoms for longer than ever before...

  • 08:29 - The Brain's First Whiff of Nicotine

    A new study sheds more light on how the brain responds to its first ever whiff of nicotine. By looking at activity in the brain tissue of a rat as itís exposed to nicotine for the very first time, Professor Daniel McGehee, at the University of Chicago, can help to understand ho...
