When mammoths roamed England

A clash of the mammoths could have taken place in what is now southern England thousands of years ago. Fossils found in Buckinghamshire and Norfolk suggest that two types of mammoth lived side-by-side in prehistoric times. Scientists believe herds of more advanced mammoths moving south from Siberia encountered primitive European ones

Scientists have released new details of a giant super-crocodile which lived around 110 million years ago and grew to the length of a bus. Sarchosuchus imperator specimens were first discovered in the Ténéré Desert in Niger in 1964, but new finds in the Sahara have made it possible to form a clearer picture of the giants

The popular overkill theory took a hefty knock today with evidence it wasn’t humans but climate change which caused the extinctions

Secrets Of Insect Flight

Scientists have puzzled for years how insects manage to fly. The bumble bee, for instance, has the aerodynamics of a tiny brick and it has been theoretically proved several times it’s impossible for it to fly. Now we’ve found out the secret of insect flight — it’s all to do with complex tiny air vortices produced from their wings

New career for ex-Soviet ‘killer’ dolphins

Trained to kill, the dolphin Diana has found a new vocation — helping autistic children to break out of their shell. Born 28 years ago, Diana was raised by her Soviet masters to serve as a weapon in the Cold War.
