| 2024-Apr-22 • 28 minutes CultureLab: Meredith Broussard on trusting artificial intelligence How much faith should we be putting in artificial intelligence? As large language models and generative AI have become increasingly powerful in recent years, their makers are pushing the narrative that AI is a solution to many of the world’s problems.But Meredith Broussard says we’re not there yet, if we even get there at all. Broussard is the author of More than a Glitch: Confronting Race, Gender, and Ability Bias in Tech. She coined the term “technochauvinism,” which speaks to a pro-technology bias humans... |
| 2024-Apr-19 • 33 minutes Weekly: Carbon storage targets ‘wildly unrealistic’; world’s biggest brain-inspired computer; do birds dream? #246Our best climate models for helping limit global warming to 1.5oC may have wildly overestimated our chances. To reach this goal, models are relying heavily on geological carbon storage, a technology that removes carbon from the atmosphere and places it underground. But it may not be nearly as effective as models have suggested, making the task of decarbonising much more difficult. Do we need to rethink our approach?Intel has announced it has constructed the world’s biggest computer modelled on the human... |

| 2024-Apr-12 • 29 minutes Weekly: The multiverse just got bigger; saving the white rhino; musical mushrooms #245The multiverse may be bigger than we thought. The idea that we exist in just one of a massive collection of alternate universes has really captured the public imagination in the last decade. But now Hugh Everett’s 60-year-old “many worlds interpretation”, based on quantum mechanics, has been upgraded.The northern white rhino is on the brink of extinction but we may be able to save it. Scientists plan to use frozen genes from 12 now dead rhinos to rebuild the entire subspecies. But how do you turn skin c... |
| 2024-Apr-08 • 39 minutes CultureLab: Jen Gunter on the taboo science of menstruation Half of the human population undergoes the menstrual cycle for a significant proportion of their lifetimes, yet periods remain a taboo topic in public and private life.

While we can expect world leaders to make some major commitments regarding renewable energy, sceptics are concerned the location of the summit will mean that fossil fuel interests end up disproportionately shaping the meeting.You ma... |
| 2023-Nov-28 • 22 minutes Science of cannabis: #1 A long history and a seismic shift Cannabis is having a moment. Half of the US population lives in a state where marijuana is legal, and 9 in 10 people nationwide support legalisation in some form. This is a stark difference from mere decades ago, when prohibition was the norm in the entire US. Meanwhile, if you live in Malta, Uruguay, Canada – and maybe soon, Germany – your entire country is one with legal recreational pot. And access to medical marijuana extends to even more countries, including the UK and Australia.But as medical and recr... |
