Scientists at Horticulture Research International have been studying natural mutations in vegetables in the hope of identifying the genes responsible for limiting uptake of caesium. The results of their quest, to be presented at the annual SEB conference suggest ‘safe’ crops could one day be grown on radioactive soil.

Four million people in Belarus, Russia and the Ukraine currently live in areas where 137Cs deposition densities to soils exceeded 37 kBq m-2 following the Chernobyl accident in

Many shark species, including the great white and mako, swim at speeds greater than their morphology should allow. Dr. Adam Summers (University of California) has discovered they achieve this speed by changing the stiffness of their body by pressurising their thick, inflexible skin. “This study could help answer questions about the evolution of the shark, especially why sharks abandoned a bony skeleton in favour of a cartilage structure,” said Dr. Summers who will be presenting his findings on Frida

The broad barred goby is a coward. A sweeping statement you may say, but even though the goby is poisonous to its predators, the cowardly fish still spends almost all its time cowering in an inaccessible coral home 20-30 cm in diameter. A new study, to be presented to the Society for Experimental biology on Wednesday 3rd April, reveals how the fish has adapted to extremely low oxygen concentrations (hypoxia) in order to avoid venturing out from its coral den.

The exotic island of Madagascar, situated off the southeast coast of Africa, was a dangerous place to live 65 million to 70 million years ago. Crocodiles swarmed in the rivers, and a 30-foot-long, meat-eating dinosaur named Majungatholus atopus stalked the plains. Like most carnivorous dinosaurs, Majungatholus had teeth perfectly suited for ripping into flesh. But what was on the menu? Until now, this question has remained a mystery. In a report published in the April 3 issue of the Journal

Scientists using NASA satellite data have found the most intense global pollution from fires occurred during droughts caused by El Niño. The most intense fires took place in 1997-1998 in association with the strongest El Niño event of the 20th century.

Bryan Duncan, Randall Martin, Amanda Staudt, Rosemarie Yevich and Jennifer Logan, from Harvard University, used data observed by NASA’s Total Ozone Mapping Spectrometer (TOMS) satellite to quantify the amount of smoke pollution from biomass b

Special modification of reverse genetics created at St. Jude allowed vaccine to be custom-made within weeks of emergence of virus

Scientists at St. Jude Children’s Research Hospital announced today the development of a vaccine against H5N1, a new lethal influenza virus that triggered the World Health Organization (WHO) to declare a pandemic alert in February 2003.

The virus appeared in birds in Hong Kong late last year and subsequently killed one of two infected people
