Material from deadly pathogens triggers alerts directly, and could speed detection. Early detection is key to slowing outbreaks of Ebola, such as the one currently spreading across west Africa that is estimated to have infected almost 1000 people, according to the latest World Health Organization report. A molecular computer could one day simplify analysis of biomedical assays like those used to diagnose Ebola, researchers say. And a new prototype device can display a fluorescent letter in the presence of nucleic acid sequences from the Ebola virus or the closely-related Marburg virus: ‘E’ for Ebola or ‘M’ for Marburg.
