NewsStudy reveals how microbes create the most toxic form of mercury
Mercury is extraordinarily toxic, but it becomes especially dangerous when transformed into methylmercury – a form so harmful that just a few billionths of a gram can cause severe and lasting neurological damage to a developing fetus. Unfortunately, methylmercury often makes its way into our bodies through seafood – but ...

NewsOptical biosensor rapidly detects monkeypox virus
Researchers have developed an optical biosensor that can rapidly detect monkeypox, the virus that causes mpox. The technology could allow clinicians to diagnose the disease at the point of care rather than wait for lab results.
