Victims of traumatic brain injuries 鈥� caused by car accidents or falls 鈥� have a better chance of survival if their body temperature is deliberately cooled for a few days. But the technique does not help children with similar injuries 鈥� according to the British researchers behind the largest ever review of 鈥渂rain cooling鈥� studies. Pankaj Sharma, Professor of Neurology at Royal Holloway, University of London led the research and says the body should be cooled quickly to get the best results.

Prehistoric Porridge Pots
Broken shards of pottery discarded in the Libyan Sahara 10,000 years ago, when the area was lush and green, carry tell-tale traces of plants that were once cooked by the primitive inhabitants. Roland Pease visits the Bristol University Labs of Richard Evershed and Julie Dunne to hear how they uncovered the origin of what could be the oldest example of bubbling cereal porridge.

Henry Heimlich
This week the death was announced of 96 year old Henry Heimlich 鈥� the American whose special manoeuvre has helped to save many thousands of lives. The upwards abdominal thrusts are now taught as part of first aid courses.

Octopuses of the Very Deep
Octopuses that live four kilometres beneath the sea surface have been discovered by German and American marine scientists. Their habitat is found in desolate plains that are littered with metal-rich nodules that have precipitated over the millennia from sea water. And that is the problem 鈥� because the area is attractive to submarine prospectors for the precious metals they could harvest there. And that could disturb the delicate deep-ocean ecological balance and interfere with the breeding of the octupus. Autun Purser of the Alfred Wegener Institute in Bremerhaven describes the discovery and explains the issues.

Mind Wandering and ADHD
Is attention deficit hyperactivity disorder actually a problem of excessive mind wandering? Children who find it hard to sit still and concentrate may be diagnosed with ADHD. Claudia Hammond hears from two teenage girls with ADHD, talking about how difficult they find it to concentrate at school. Philip Asherson is Professor of Clinical and Molecular Psychiatry at Kings College London 鈥� and he says the idea that mind wandering might play a big part in ADHD is now being taken seriously.

Migrating Insects
Trillions of insects migrate over southern England every year 鈥� moving north in the spring and south in the autumn. These mighty migrations were tracked down using radar and high-flying experimental balloons. The University of Exeter鈥檚 Jason Chapman explains.
