Last April Swedish scientists discovered high levels of a potentially cancer-causing chemical called acrylamide in wide range of starch-containing foods that are fried or baked, particularly french fries, potato chips and crackers. The announcement received worldwide publicity. But at the time, no one knew where the acrylamide came from, how it was formed, or, indeed, if there is a link between acrylamide in food and cancer. The findings were quickly confirmed by the British Food Standards Agency. Ea

Using models that simulate the interaction between global climate and land ecosystems, atmospheric scientists from the Lawrence Livermore National Laboratory have shown that compensating for the carbon dioxide “greenhouse effect” by decreasing the amount of sunlight reaching the planet (geoengineering) could create a more vigorous ecosystem while helping to curb global warming.

The study suggests that planetary-scale engineering projects to lessen the amount of solar radiation reaching the

A broad group of discoveries about the biological powers of “small-RNA” molecules, some of which were made by researchers at Oregon State University, will be hailed on Friday as the scientific “Breakthrough of the Year” by the journal Science. Science is published by the American Association for the Advancement of Science, the world’s largest general scientific society, and each year the prestigious journal identifies what it believes were the top 10 research advances of the year.

Pioneering new solvent systems which are recyclable and environmentally compatible have been developed by researchers at the University of Leicester.

The team, led by Drs Andy Abbott and David Davies, has developed a wide range of new solvents made from bulk commodity materials such as urea (a common fertiliser) and vitamin B4. These have been studied extensively in recent years as they offer a potentially clean way to carry out chemical processes. They are non-volatile whilst liquid over a

The fact that many animal species, such as herds of antelope or shoals of fish, live together in herds is well understood: there is safety in numbers. Why limpets live together is a mystery, but ecologist Tim Theobalds thinks he has come up with the answer, and his findings could have important implications for their conservation and commercial collection.

Speaking at the British Ecological Society’s Winter Meeting, being held at the University of York on 18–20 December 2002, Theobalds of th

Novel developments in electronics which are giving ecologists important new tools to quickly and easily measure biodiversity will be described at the British Ecological Society’s Winter Meeting, being held at the University of York on 18–20 December 2002.

Speaking at the meeting, electronics expert and entomologist Dr David Chesmore from the University of York will explain a novel method of identifying different grasshopper species using time domain signal coding and artificial neural netwo
