Babbage: The fight to link contact sports to long-term brain injuries

02/22/23 • 40 min

1 Listener

Over the past few years, hundreds of rugby players have launched class-action lawsuits against the sport’s governing bodies, accusing them of failing to do enough to protect players from head injuries. They say that repeated blows to the head, sustained through years of playing rugby, or other sports, have caused neurodegenerative conditions like dementia, motor neurone and Parkinson’s diseases. But can scientific evidence prove a link between contact sports and these brain conditions?

Alix Popham, a Welsh former professional rugby player, tells his story of head injuries on the pitch and his desired outcomes from the lawsuits. Plus, Lauren Pulling, who runs the Drake Foundation, explains the current state of neuroscientific research and what further studies are needed to investigate the connection. Alok Jha hosts with Natasha Loder, The Economist’s health editor, and Georgia Banjo, our Britain correspondent.

Babbage: Will bird flu cause the next human pandemic?

Over the past 18 months, the largest-ever recorded avian influenza outbreak has decimated bird populations around the world. But recently bird flu has spread to mammals. Last week, Peru reported the deaths of 585 sea lions. If the virus has mutated to enable mammal-to-mammal transmission, that could be an intermediate step towards human-to-human transmission. How worrying is this threat?

Susan Davies, CEO of the Scottish Seabird Centre, describes how the H5N1 avian flu has affected populations of wild birds. Ian Brown of Britain’s Animal and Plant Health Agency explains why the dynamics of this outbreak are concerning scientists. Plus, we ask Marion Koopmans, head of viroscience at Erasmus MC, why she’s more worried than ever about a human influenza pandemic. The Economist’s Slavea Chankova also compares the influenza threat to the covid-19 pandemic. Do we have enough tools in our arsenal? Alok Jha hosts.

Babbage: The scandal of scientific fraud

There is a worrying amount of fraud in medical research. As many as one in 50 research papers may be unreliable because of fabrication, plagiarism or serious errors. Fabricated data can influence the guidelines which doctors use to treat patients. Misguided clinical guidelines could cause serious illness and death in patients. Fraudulent studies can also influence further research programmes—recent findings suggest that manipulated images may have resulted in scientists wasting time and money following blind alleys in Alzheimer’s research for decades. What can be done to combat scientific malpractice?

Dorothy Bishop, a retired professor of psychology at the University of Oxford, explores the motivation behind fraudsters in research. John Carlisle, an anaesthetist and an editor of the journal Anaesthesia, explains the impact of fraud and how to detect it in research papers. Also, Elisabeth Bik, a former microbiologist and a full-time scientific image detective, discusses the consequences of whistle-blowing on both sleuths and the fraudsters. Plus, The Economist’s health-care correspondent, Slavea Chankova, investigates how to overcome the worrying unwillingness on all sides to do anything about fraud in research. Alok Jha hosts.
