easy rabies cure: Tobacco plants have been genetically modified to produce proteins used to combat the rabies virus. Till now, the only way to fight the virus was to use antibodies derived from either horses or humans; but they are difficult to get. Researchers from the Thomas Jefferson University, USA, have now inserted DNA coding of the human antibodies into the tobacco plants. The new antibodies are as efficient as the ones used at present.

biodetectors: Scientists from US-based National Oceanic and Atmospheric Administration have started using sensors to map wind patterns and provide information in case of a chemical or biological attack. The prototypes, in the form of nine-meter high aluminum towers, are being tested in New York and Washington DC. The sensors measure wind strength and direction 10 times per second. The data is downloaded via the Internet to computers that simulate a
