| The clay tablet, which is 6cm in diameter |
Science & Technology
A clay tablet that has baffled scientists for 150 years has been identified as a witness's account of the asteroid suspected of being behind the destruction of Sodom and Gomorrah.
Garments that can measure a wearer's body temperature or trace their heart activity are just entering the market, but the European project BIOTEX weaves new functions into smart textiles. Miniaturised biosensors in a textile patch can now analyse body fluids, even a tiny drop of sweat, and provide a much better assessment of someone's health.
It is 7 o'clock in the morning. You check yourself in the mirror, adjust your collar, and consider the hectic day ahead. But at least you know that the stress won't damage your health, for this is no ordinary set of clothes you are wearing. Embedded within the fabric are numerous sensors, constantly monitoring your vital signs. If danger signs are detected, the garment is programmed to contact your doctor - and send a text message telling you to take it easy.

Thousands of viewers have embraced CBC-TV's experiment with BitTorrent, but many Canadians have found their attempts to access a CBC show online restricted by their internet service providers.
Scientists in the United States have discovered how a squid is capable of operating its knife-sharp beak without harming its soft, gelatinous body.
They are separated by a vast ocean and by millions of years, but tiny prehistoric bones found on an Australian farm have been directly linked to a strange and secretive little animal that lives today in the southern rainforests of South America.

Whether you are a Mac person or a PC person, even the briefest exposure to the Apple logo may make you behave more creatively, according to recent research from Duke University's Fuqua School of Business and the University of Waterloo, Canada.
In work to be published in the April issue of the Journal of Consumer Research, Professors Gavan Fitzsimons and Tanya Chartrand of Duke, and Gráinne Fitzsimons of Waterloo, found that even the briefest exposure to well-known brands can cause people to behave in ways that mirror those brands' traits.

The mechanism behind different types of lightning may now be understood, thanks to a combination of direct observation and computer modeling reported by a team of researchers from New Mexico Tech and Penn State.
"Our explanation provides a unifying view of how lightning escapes from a thundercloud," the researchers report in the April edition of Nature Geoscience.
Most people see lightning strikes that go from clouds to the ground, but some lightning goes upward, forming blue jets and gigantic jets. Perhaps the most dangerous lightning appears as "bolts from the blue" -- lightning that begins upward, but then moves sideways and then downward to hit the ground as much as three miles from a thunderstorm.

The Druids of ancient times had no illusions about the stability of our planet, or about the other planets in our solar system. They had inherited knowledge of earlier catastrophic happenings, and this led them to believe that the earth would be destroyed by fire and water. But they always preached that the universe and the souls of those living in it are indestructible. In the legendary voyage of Snedgus and McRiagla there is an island with two lakes, one of fire and the other one of water.
Washington : The new 5 million dollars medical and surgical simulation training centre located at the Johns Hopkins Outpatient Center in East Baltimor, which opened in March, has some very unique new staff members - robots.
What is the fastest a dolphin can swim? Near the surface, no more than 54 kilometres per hour. Why? Because it hurts it to swim faster.
Those are the findings of a pair of researchers from the Israel Institute of Technology in Haifa. But tuna, they say, do not suffer the same problem.
Gil Iosilevskii and Danny Weihs carried out a series of calculations to model the tail and fins of fish such as tuna and mackerel, and cetaceans such as dolphins. The aim was to determine what limits the maximum speed at which these creatures can swim.
