Tobacco industry deceived public with ‘low tar’ cigarettes

The tobacco industry has deliberately deceived the public with “low tar/light” cigarettes, reveals an analysis in a special supplement to Tobacco Control. Industry documents show that companies recognised that low tar products were as dangerous as regular cigarettes, yet marketed them as healthy alternatives.

The authors analysed trade sources and internal US tobacco company documents. These show that the industry feared mounting evidence linking tobacco with lung cancer would discourage smo

Depleted uranium soils battlefields

Report assesses chemical effects of Gulf war weapon.

Depleted uranium in weapons may have left some soldiers with kidney damage and could cause long-term environmental contamination, say British scientists. Their independent review calls for accurate exposure tests and long-term environmental monitoring in combat zones.

Depleted uranium (DU) is a dense radioactive substance. It was used in weapons to punch through heavily armoured vehicles during the Gulf War and Kosovo conf

Tomorrow`s Leaders Told to Invest in Research

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 She answered questions fr

What Shall We Do With Nuclear Waste?

There are two ways of dealing with the problem of nuclear waste. The first one is the easiest but not the most sensible: you can simply bury nuclear waste products and try to forget about them. However, this way does not seem to be the most rational. It seems much more attractive to try to derive some benefit from the situation. In this case it is worth extracting the compounds that could be used in future from the whole mass of nuclear wastes. In the first instance, these are non-burnt uranium and p

Tackling Drunk-driving

There are no in-car methods of detecting that a driver is too drunk to drive – until now. A team at Bristol University, led by physiologist Dr Dilwyn Marple-Horvat, has found a new way of detecting whether a driver has drunk too much to be fit to be at the wheel.

To assess a driver`s fitness to drive, a new device has been created that measures the degree of co-ordination between hand and eye. It uses: an in-car eye-tracker; a system that continuously monitors steering wheel movements; and

Virtual-reality mummy

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
