Scientists identify prion's infectious secret

... prion could cross the species barrier but did not identify the mechanism. Tessier found that this synthetic prion contained two recognition elements, one for baker’s yeast and one for pathogenic fungi. When the prion was placed with peptide fragments from baker’s yeast, the baker’s yeast recognition element ...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

... very similar to that used by the immune system to identify a virus or bacteria in the body. The organism attacks an infection by generating antibodies which hook onto, for example, a specific type of virus. Hence the virus is identified and may be eliminated. In the case of the sensors, specific antibodies f...
