麻豆约拍

Health officials are urgently trying to contain the spread of a new coronavirus in China and beyond. We fact-check a particularly hyperbolic claim about its spread that鈥檚 been doing the rounds on social media. Elsewhere, a loyal listener has told us about a smelly statistic emanating from Radio 4. We nose around the relationship between our olfactory organs and emotions. And Bill Bryson reacts to our work answering his question about an opinion piece in The Wall Street Journal about gun ownership and homicide rates.
