It seems that early dinosaur precursors to birds that had beaks rather than teeth gave them the advantage to survive the meteor crash almost 66 million years ago. Jack Stewart talks to palaeontologist, Derek Larson, from the Philip J. Currie Dinosaur Museum, in Alberta Canada.

Quantum Games
Scientists in Copenhagen are developing a quantum computer. To help them solve a particular problem, they have turned to human brain power, harnessing our ability to play computer games. Adam Rutherford talks to Jacob Sherson from Aarhus University in Copenhagen.

QB50
A European project called QB50 plans to gain greater insight into a section of the atmosphere called the thermosphere, by sending 50 small satellites, known as CubeSats, into orbit this summer. Marnie Chesterton talks to scientists at UCL’s Mullard Space Science Laboratory in southern England.

Concussion Test
American doctors say they’re just five years away from a pitch-side blood test to spot concussion – which is an injury caused for example by a bang to the head. Claudia Hammond discusses with Dr Linda Papa the work by researchers at the Orlando Regional Medical Centre in Florida who have detected two substances which are released into the blood stream after a brain injury which may help to develop a simple blood test.
