Social distancing policies, such as cancelling high-density gatherings, discouraging handshakes and asking people to increase their distance from each other will delay a coronavirus pandemic and help health authorities plan resources, according to epidemiologist Dr Vittoria Colizza who is modelling the spread of Covid-19 and the effectiveness of interventions.
Scientists are drawing on nature’s clever ways to build structures and produce iridescence.
Infection-halting therapies being explored include neutralising antibodies.
Metagenomics can help us spot emerging diseases such as coronavirus, says virologist Marion Koopmans.
