Should we ban cats?

Science Weekly ·

2025/02/18

The Scottish first minister, John Swinney, was recently forced to deny plans to ban cats after a report from independent experts said the species was a threat to Scotland’s wildlife.

Ian Sample hears from cat-owner Madeleine Finlay and the ecologist Prof Robbie McDonald about the best ways to reduce our feline companions’ impact on wildlife without affecting welfare.

2025/02/13

Recently, a group of world-leading scientists called for a halt on research to create ‘mirror life’ microbes amid concerns that the synthetic organisms would present an ‘unprecedented risk’ to life on Earth. Ian Sample tells Madeleine Finlay about why this work initially seemed exciting for scientists and what the risks of it continuing could be. And Kate Adamala, assistant professor of genetics, cell biology and development at the University of Minnesota, describes what made her change her mind

2025/01/09

The Oxford English Dictionary announced its word of the year at the end of 2024: brain rot. The term relates to the supposedly negative effects of consuming social media content, but it struck a chord more widely with many of us who feel we just don’t have the mental capacity we once did. Gloria Mark, a professor of informatics at the University of California, Irvine, has been studying our waning attention spans for 20 years.

2024/12/31

For the regular drinker, the studies that say a daily tipple is better for a longer life than avoiding alcohol completely are a source of great comfort. But a new analysis challenges that thinking and says it was based on flawed research that compares drinkers with people who are sick and sober. In this episode from August, Madeleine Finlay hears from the study’s lead author, Tim Stockwell, a scientist at the Canadian Institute for Substance Use Research at the University of Victoria, to find out
