New lab-on-a-chip can process and present results rapidly

The chip, developed at Imperial College London and known as TriSilix, is a 'micro laboratory' which performs a miniature version of the polymerase chain reaction (PCR) on the spot. PCR is the gold-standard test for detecting viruses and bacteria in biological samples such as bodily fluids, faeces, or environmental samples.

SARS-CoV-2 deletion mutations may have attenuated infectivity in some strains

A team of researchers at the University of Hong Kong has identified a panel of SARS-CoV-2 variants, called Del-mut, which contains a deletion in the S1/S2 junction. Upon investigating one of the deleted variants in animal models, they found that Del-mut-1 is attenuated in its ability to cause disease or pathological changes.
