#163 Antidepressants; Exoplanets; California’s megadroughts – the latest news in science

Season 1, Ep. 163

A vaccine for the respiratory virus RSV may be ready this year. In fact, after decades of efforts, successful vaccines have arrived like buses, with three of them on the way. As a particularly devastating virus for young children and the elderly, the team explains just how impactful these new vaccines will be.

You may have read headlines that Earth’s core is changing direction - but the team explains why it’s not all it’s cracked up to be. They also bring less-than-thrilling news for the existence of life in the universe, as we may have been overestimating how many planets are out there that have the right conditions for life.

Following intense rainfall, floods and disaster declarations, California finally has a dry forecast. But, the team asks, has all this water helped ease the State’s worst-in-a-century drought? And will we see more of these dramatic swings in weather as climate change worsens?

Science has shown what most people who take antidepressants already know - that they blunt both bad and good emotions. The team explores the implications of this new study.

You may be noticing a few bonus episodes popping up in your feed lately. The team shares a teaser of the latest ones, including a discussion about ‘tipping points’ with climate scientist Tim Lenton, and a chat with fungal pathogen expert Mat Fisher about the new fungal horror TV show The Last of Us.

On the pod are Rowan Hooper, Penny Sarchet, James Dinneen, Michael Le Page and Leah Crane. To read about these subjects and much more, you can subscribe to New Scientist magazine at
