Friction pushes a spinning egg from horizontal to vertical.

Mathematicians have cracked the conundrum of the spinning egg. A hard-boiled egg spun on its side flips upright because of friction between the egg and the table, they calculate 1 .

The egg’s elevation appears paradoxical. Its centre of gravity moves up – making the system seem to be gaining energy.

In fact, spinning energy, translated into a horizontal force, pushes the egg upright, sa

Footprints and a fire found from 20,000 years ago.

Handprints and footprints 20,000 years old reveal that people lived on the Tibetan plateau at the height of the Ice Age – 16,000 years earlier than scientists had thought. The newly found signs of life cast doubt on the idea that a glacier a kilometre thick covered the plateau at that time.

David Zhang and S. H. Li of the University of Hong Kong found the marks of at least six individuals, including two children, in marble-l

Ethiopian fossil suggests early humans were one big family.

A one-million-year-old skull unearthed in Ethiopia hints that our long-extinct cousins Homo erectus were a varied and widespread bunch, much like today’s humans. The find may undermine previous claims that H. erectus was in fact made up of two different species. Homo erectus , which means ’upright man’, appeared about 1.8 million years ago. Because of its posture and large brain, it is regarded as t

A lack of investment in corporate research may be counterproductive to industry says Dr Elsa Reichmanis, director of Materials Research at Lucent Technologies` Bell Labs, New Jersey, USA. In an exclusive Tomorrow’s Leaders online broadcast, Reichmanis stated ‘In order to succeed in the long term, investment in the future is a must, and that means investment in research.’

Dr Reichmanis made her remarks during a one-hour live broadcast at www.tomorrows-leaders.net. She answered questions fr

Technology unravels mysteries of ancient corpse.

Glassy-eyed with a hole in the head – meet Nesperennub, the virtual-reality mummy. A new three-dimensional reconstruction of his insides swoops through musty layers of linen to penetrate his holy skull, without putting the ancient artefact at risk.

Egyptologist John Taylor smuggled the British Museum’s sealed coffin into a hospital computerized tomography (CT or CAT) scanner after hours. The resulting 1,500 flat scans hav

Research by a University of Sunderland psychologist has revealed that one in four people may have a special gift for predicting uncertainties like the weather.

Tests carried out by Professor Richard Heath, from the university’s Business School, also showed that this uncanny ability could possibly extend to the financial markets.

During his research volunteers were shown temperature figures for the previous eight days and were asked to predict the following four days.
