BBC Radio 4 ‘Inside Science’ talks about satellite navigation in the UK; the science of the World Wide Web and Neolithic genomics.
Is the UK losing its way when it comes to satellite navigation? There’s GPS from the US, but other countries and regions, including Russia, China, India and Japan, either have, or are building, satellite navigation systems of their own. The EU has Galileo, but with Brexit, Britain is no longer involved. The Government has announced that it’s just acquired a satellite technology company called OneWeb. It’s primary role is enhanced broadband, but there’s talk of adding in a navigation function to the constellation of satellites. But how feasible will that be?
In an era of cyber-crime, misinformation, disinformation, state-sponsored attacks on rival countries’ infrastructure, government-imposed internet shutdowns in places like Eritrea and Kashmir, the World Wide Web is an increasingly dark and troubled place. Making sense of how the internet has changed from the democratic, sharing, open platform it was designed to be, and predicting what’s next, are the web scientists. Professor Dame Wendy Hall, Regius Professor of Computer Science at the University of Southampton, and a co-founder of the whole field of web science, is hosting an online, annual conference this week. The theme this year is ‘Making the web human-centric’.
Communal burial sites tend to suggest an egalitarian society, where everyone is considered equal. And this is what we expected the Neolithic societies that spread across Europe with the birth of agriculture around 6000 years ago would be. But DNA evidence from a single human, NG10, buried in 3200 B.C.E in the vast tomb of Newgrange, 25 miles north of Dublin, in Ireland, shows very strong inbreeding. Couple this with the fact the body was buried and not cremated and placed in a highly adorned chamber. Does this indicate an elite ruling class where marrying one’s close kin was the order of the day? Dr. Lara Cassidy, palaeogeneticist at Trinity College Dublin, decoded NG10’s DNA and she tells Adam Rutherford the story.

The spread of misinformation is crippling our fight against the coronavirus. Social media and a deeply partisan divide are fueling what the World Health Organization calls an “infodemic,” which is just as urgent as the virus itself.
Chest pain is a common chief complaint. It may be caused by either benign or life-threatening aetiologies and is usually divided into cardiac and non-cardiac causes. James E. Brown, Professor and Chair, Wright State University Boonshoft School of Medicine, Kettering, Ohio, gives us an overview of assessing chest pain in the emergency setting.

Researchers have run numerous military-style simulations to predict the consequences of fictitious viral outbreaks. We discuss how these simulations work, what recommendations come out of them and if any of these warnings have been heeded.
