In what would be the microbiological equivalent of discovering buried treasure, a team of Antarctic bioscientists, led by Jenny Blamey of the Biosciences Foundation of Santiago, Chile, recently discovered a trove of some 300 microorganisms, 70% of which are previously unknown to science.
A transgenic chicken has been developed that blocks transmission of the avian flu to other chickens. The new technique — some aspects of which are not clear even to the geneticists developing it — holds out great promise for preventing human illness as well as unnecessary animal deaths. But nothing is quite that simple when
The National Research Council reports that the use of genetically engineered crops results in less harm to wild life, less soil erosion, and greater cost savings. Its findings could impact agricultural practices in other nations.
