Sight for sore eyes

An inventive breakthrough from the Applied Optics Group at the University of Kent at Canterbury (UKC) is set to revolutionise current methods of eye examinations.

Professor David Jackson, Dr Adrian Podoleanu and Dr John Rogers, who gained his doctorate at Kent, have developed an instrument known as an Optical Dual Channel Tomograph. The instrument blends together two imaging technologies. Although in its early stages, it is already being used by ophthalmologists and researchers at New York`

Survey of U.S. Streams Finds Numerous Contaminants

Many chemicals commonly used in medications such as over-the-counter painkillers or birth control pills end up far from their intended destination – in American streams. According to a new report, published online today by the journal Environmental Science and Technology, a number of the waterways contain complex cocktails of compounds.

The 30-state study, conducted by the U.S. Geological Survey, tested 139 streams for 95 organic contaminants – ranging from medications and hormones to inse

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 www.tomorrows-leaders.net. 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
