Researchers at the Universities of Warwick and Keele are being supported by the Economic and Social Research Council to watch the popular game show Who Wants to be a Millionaire? The globally broadcast show is a treasure trove of data on how all sorts of people of different ages and genders and nationalities perceive and act on risk.
One of the researchers, economist Professor Ian Walker from the University of Warwick said:

“Many decisions involve weighing up potential gains and losses w

Wound healing appears generally a banal event, but in a certain proportion of cases it evolves inappropriately in hypertrophic scars resulting in skin and organ deformations. This is due to an excess of wound contraction, a phenomenon that generally helps to close the wound. Hypertrophic scarring is observed frequently in burned patients.

For the past 30 years, Professor Giulio Gabbiani and his team are interested in the role of myofibroblasts in wound contraction. Myofibroblasts, specializ

Of the estimated 10,000 to 100,000 microbial species that inhabit our planet, scientists can only coax a few thousand to grow in the laboratory. As a result, efforts to categorize the vast diversity of microbes are lagging far behind attempts to classify plants, animals and insects. Now a report published in the current issue of the journal Science suggests that some of these so-called uncultivable microorganisms might not be so out of reach after all.

A research team jointly involving the IRD, the CEA and the CNRS has very recently found phytochromes in a strain of nitrogen-fixing bacterium, Bradyrhizobium (1), symbiont on certain tropical leguminous plants (the Aeschynomene). Techniques of molecular biology, biophysics and biochemistry revealed that the newly-discovered phytochrome has an essential role as regulator of the bacterium’s photosystem synthesis. An identical function was shown in the photosynthetic bacterium Rhodopseudomonas palustris

A model of a system for growing plants to plan biological experiments in space has just left the company of ROVSING, in Ballerup near Copenhagen, on its way to ESA’s European Space Research and Technology Centre (ESTEC) in the Netherlands.

The full name of this experiment reference model is European Modular Cultivation System Experiment Reference Model (EMCS ERM). This will be used at ESTEC to plan and carry out experiments for growing plants in space. Then in 2003 the EMCS Flight Model will

A team of UK astronomers announced this month the discovery of cannibalistic stars that explain one of the mysteries surrounding the Big Bang. The stars are almost as old as the Universe and they reveal what space was like in the very beginning.

The team from the Open University found that a group of 14-billion-year-old stars were all in a spin (literally) because of a nasty phase earlier in their lives. They were, in short, cannibalistic stars. The scientists` discovery not only explains
