Dutch ecologists plea for scientific research to aid risk assessment
A survey among nine prominent Dutch ecologists has identified gaps in knowledge on the potential effects of Bt-crops on food chains and ecosystems. Bt-crops have been modified to express a bacterial gene that codes for a toxin that kills certain groups of insects. The toxin is continuously produced in all plant tissues and target as well as... view more... (2003-08-28)

Nanometric butterfly wings created
A team of researchers from the State University of Pennsylvania (USA) and the Universidad Autónoma de Madrid (UAM) have developed a technique to replicate biological structures, such as butterfly wings, on a nano scale. The resulting biomaterial could be used to make optically active structures, such as optical diffusers for solar panels. view more (2009-10-09)
