NewsStudy shows N95 masks near-perfect at blocking escape of airborne COVID-19
In a head-to-head comparison of masks worn by people with active COVID-19, the inexpensive ‘duckbill’ N95 came out on top, stopping 98% of COVID-19 particles in the breath of infected people from escaping into the air.

NewsScientists uncover factors potentially contributing to the decline of the mpox outbreak
Researchers hypothesise that it is not likely that preventive vaccination was a driver of the outbreak’s decline in the Netherlands, as the mpox incidence started to decline before the start of the vaccination programme.

NewsAncient viral DNA in the human genome linked to major psychiatric disorders
New research led by King’s College London has found that thousands of DNA sequences originating from ancient viral infections are expressed in the brain, with some contributing to susceptibility for psychiatric disorders such as schizophrenia, bipolar disorder, and depression. Published in Nature Communications, the study was part-funded ...
