“We were a model in 2020,” says Rafael Radi, a biochemist at the University of the Republic in Montevideo. “Unfortunately, things are not following the same path in 2021.” By Luke Taylor – Complacency and a coronavirus variant help to explain why Uruguay, once a pandemic success story, couldn’t withstand the surge now rocking South America. Once looked to as a global model for how to respond to the COVID-19 pandemic, Uruguay has in recent months lost its grip on the coronavirus SARS-CoV-2. It’s now one of several countries in South America struggling to contr...

Gravitational wave search no humdrum hunt 28 May 2021 The gentle hum of a spinning neutron star is very faint and almost impossible to detect The hunt for the never before heard "hum" of gravitational waves caused by mysterious neutron stars has just got a lot easier, thanks to an international team of researchers. Gravitational waves have only been detected from black holes and neutron stars colliding, major cosmic events that cause huge bursts that ripple through space and time. The research team, involving scientists from the LIGO Scientific Collaboration (LSC), Virgo Collaboration and the...

Lycra louts fiddled files to make them faster, but automation overtook their antics Share Copy Virtual cycling company Zwift has banned two riders for fiddling with data they uploaded to the service, and which helped them to do better in races. Zwift allows cyclists to race each other in a virtual world – after first bolting their bikes to a static trainer that allows them to pedal without going anywhere while measuring their performance by tracking power output and the speed at which riders pedal. The service quickly became a venue for e-cycling competitions, and in 2016 recognised...
