Chimps, bonobos and humans have more in common than you might think
Episode 292Chimps are often seen as our hyper-aggressive ancestral cousins, while bonobos are famously more peaceful and caring. But studies of their sexual habits and practices show they are much more alike than we realised. Both apes appear to use sex and genital contact not just to reproduce, but also to smooth tensions in the group, deal with stressful situations and handle conflict at feeding time. Sophie Bergudo has recently finished a PhD on chimp behaviour and shares insights from her ti

Life-saving mice perform first aid; tiny lab-grown human brains; making skyscrapers and hair condition from wood
Episode 290Mice have been found saving the lives of their cagemates by performing a resuscitation technique similar to CPR. After opening the mouth of an unconscious mouse, the “attending mouse” yanks up its tongue to clear the airways and dislodges anything that’s stuck. This remarkable discovery shows that empathy and consolation behaviour is more widespread in mammals than we thought, and hints at a mouse theory of mind.Tiny, lab-grown bits of human brain are being combined to create somethin

Why chimps are still in the Stone Age and humans are in the Space Age
Episode 277Chimps are an intelligent species, capable of using tools and developing culture - so why have humans surpassed them to such a huge extent? How is it that we are busy exploring space while chimps remain stuck in the Stone Age? It’s long been thought it’s because their culture doesn’t evolve cumulatively, but that assumption has just been challenged. Hear from Cassandra Gunasekaram, the lead author of a paper that shows chimp culture develops in a more complex way than we real

Climate overshoot - when we go past 1.5 degrees there is no going back
Episode 271If we overshoot 1.5 degrees of global warming, there is no going back. The hope has long been that if - and when - we blow past our climate goals, we can later reverse the damage. But there’s no guarantee we can bring temperatures back down, according to a paper published in Nature this week. The report suggests it would take decades to get back to normal - and some of the more devastating consequences will be irreversible. Hear from a variety of experts on the problem of cli

Does loneliness really cause ill health?; A time-travelling photon; The supermassive mystery of early black holes
Episode 268Research has long linked loneliness to surprising health conditions, including diabetes and some cancers. The assumption has been that loneliness in some way causes these issues, perhaps through increased stress or inflammation. But in a study of tens of thousands of people’s biomedical data, that link has gotten more complicated. Where does this leave the relationship between loneliness and health, and the public health programs that are trying to tackle both?Supermassive bl

Shocking source of deep sea oxygen; Alcohol really is unhealthy; ‘Green’ plastic downsides
#260Most of us imagine plants when we think about the production of oxygen. But turns out, in the deep sea, metal-rich rocks also seem to generate oxygen. This surprising discovery suggests they may have a much more important role in their ecosystem than we originally thought – and is fueling more calls to ban deep sea mining, which would target these same rocks. Drinking a glass of wine once in a while can’t be that bad, right? Over the decades we heard that drinking a little alcohol m

Why we should drill a massive hole in the moon; banning fossil fuel advertising; how to stop being lonely
#253The moon may hold the answer to a decades-long physics conundrum – all we need to do is drill several kilometres into its surface. For years, physicists have been searching for protons that fall apart or decay into other particles, but they’ve always come up empty handed. So why do they think they might find them on the moon?

Google’s AI search problem; time is a quantum illusion; can we stop ageing?
#252It is not wise to stick cheese on your pizza with glue, even if Google tells you to do it. This is just one recommendation in a string of blunders made by Google’s new AI search engine. It uses a large language model to summarise your searches, but clearly it’s not always working as planned. Can (and will) the company fix it? No matter what language you speak, when you hear the word “bouba”, you probably imagine a round shape. And “kiki’ will likely make you think of a sharp shape.

#249Do whales have their own alphabet? We’ve long thought the clicking sounds that sperm whales make is their way of chatting to each other, but those clicks may be even more sophisticated than we realised. After analysing whale recordings, researchers suggest the different click patterns are complex enough to form an alphabet – the closest thing to human communication we’ve yet seen in animals.
