However the researchers say on their own these genetic factors are not determinants of how sick people will become. Underlying health, age and sex and a range of environmental and social factors are likely more important says Andrea Ganna from Finland’s Institute of Molecular Medicine who crunched the numbers. The Royal Society Summer Exhibition has just opened. And this year its an opportunity for more people to get involved than ever before – the event is taking place online. There are a number of workshops and interactive games. We speak to a couple of the participants. Caroline Orr from Teesside University talks about research using supercomputers to make microbes produce a range of biofuels that could replace petrol
