01:14 A simple switch to reduce racist ratings A study of almost 70,000 ratings showed that racial discrimination could be eliminated from an online platform by switching from a five-star rating system to a thumbs up or down. The platform connected customers to workers who performed home repair jobs, and prior to the shift people categorised by the study authors as ‘non-white’ had lower ratings an...

In this episode: 00:45 An elusive, cosmic neutrino with a record-breaking energy An enormous array of detectors, deep under the Mediterranean Sea, has captured evidence of the highest-energy neutrino particle ever recorded, although researchers aren’t sure exactly where in the cosmos it originated. Calculations revealed this particle had over 30 times the energy of previously detected neutrinos. T...

In episode 2 of 'What's in a name' we look how choosing names can help, or hinder, attempts to communicate important messages. Categorizing things is central to science. And there are dozens of systems scientists have created to name everything from the trenches on the sea bed to the stars in the sky. But names have consequences. In our series What’s in a name we explore naming in science and how...

In this episode: 00:45 How arithmetic skills don’t transfer between applied and academic environments Mathematics skills learnt in real-world situations may not translate to the classroom and vice versa, according to a new study. A team surveyed children in India who work in markets, to see whether the skills they learnt there transferred to the classroom. While proficient at solving market-based...

The explosive improvement in artificial intelligence (AI) technology has largely been driven by making neural networks bigger and training them on more data. But experts suggest that the developers of these systems may soon run out of data to train their models. As a result, teams are taking new approaches, such as searching for other unconventional data sources, or generating new data to train th...

In this episode: 00:46 Evidence of ancient brine reveals Bennu’s watery past Analysis of samples taken from the asteroid Bennu reveal the presence of organic compounds important for life, and that its parent asteroid likely contained salty, subsurface water. Collected by NASA’s OSIRIS-REx mission, these rocks and dust particles give insights into the chemistry of the early Solar System, and sugges...

00:56 How the paths to professorship vary A huge analysis of hiring practices has revealed that criteria to get a promotion to full professorship is hugely variable around the world. The authors suggest that this variability results in researchers from countries that value one type of metric being locked out of professor positions in others. They hope that the database of hiring practices created...

00:46 Designing new antivenoms to treat snakebites Researchers have shown that machine learning can quickly design antivenoms that are effective against lethal snake-toxins, which they hope will help tackle a serious public health issue. Thousands of people die as a result of snakebites each year, but treatment options are limited, expensive and often difficult to access in the resource-poor setti...

Marc Abrahams created the Ig Nobel prizes in 1991, after years of collecting examples of weird research that he included in the  Journal of Irreproducible Results . The aim of these satirical awards is to honour achievements that “make people laugh, then think”. While the initial response from the scientific community was mixed, last year the prize received more than 9,000 nominations. Severa...

02:54 The death star moon and a win for the little guys The shifting orbit of one of Saturn’s moons indicates that the satellite has a subsurface ocean, contradicting theories that its interior is entirely solid. The finding calls for a fresh take on what constitutes an ocean moon. Nature Podcast:  14 February 2024 News and Views:  Mimas’s surprise ocean prompts an update of the rule boo...

01:11 “Ozempic you’re able” In the first of our annual festive songs celebrating the science of the past year, we pay homage to Ozempic, or Semaglutide, that's able to tackle obesity, diabetes and potentially a whole lot more. 05:20 A very scientific quiz We gather an all-star cast and see how well they can remember some of the big science stories from 2024 in our annual festive quiz. 21:31 “CAR T...

Categorizing things is central to science. And there are dozens of systems scientists have created to name everything from the trenches on the sea bed to the stars in the sky. But names have consequences — unintended or otherwise. In our new series  What’s in a name  we’ll explore naming in science and how names impact the world — whether that’s how the names of storms impact public safe...

00:45 A potential treatment for pre-eclampsia Researchers have shown in mice experiments that an mRNA-based therapy can reverse the underlying causes of pre-eclampsia, a deadly complication of pregnancy for which treatment options are limited. Inspired by the success of mRNA vaccines, the team behind the work designed a method to deliver the genomic instructions for a blood-vessel growth factor di...

Zoologist Arik Kershenbaum has spent his career studying animals and how they communicate in the wild. In his book  Why Animals Talk: The New Science of Animal Communication , Arik takes a deep dive into the various forms of communication, from wolf howls to gibbon songs, to look at how different species get their points across, why they do it the way they do, and what insights they provide i...

00:48 Chemotherapy efficacy varies with the menstrual cycle Breast cancer cells are more susceptible to chemotherapy at certain points in the menstrual cycle, new data in Nature suggests. Researchers studied the equivalent hormonal cycle in mice and found that during the oestrous phase, where progesterone levels are low, tumours are more susceptible to chemotherapy. The same effect was shown in hu...

AI tools that help researchers design new proteins have resulted in a boom in designer molecules. However, these proteins are being churned out faster than they can be made and tested in labs. To overcome this, multiple protein-design competitions have popped up, with the aim of sifting out the functional from the fantastical. But while contests have helped drive key scientific advances in the pas...

00:50 Fossilised faeces give news insights into dinosaurs’ diets and rise A huge collection of fossilised digestive contents has provided clues as to how dinosaurs grew to become the dominant animals on the planet. Why these animals rose to dominance has been unclear, with one theory proposing that a chance event wiped out other species, whereas another suggests that dinosaurs had adaptations that...

00:45 A squid-inspired device for needle-free drug delivery Inspired by squids’ ability to shoot ink, a team of researchers have developed swallowable devices that can deliver tiny jets of drugs directly into the gut lining, circumventing the need for needles. Previous studies have shown that most people prefer to take medication in pill form, rather than as an injection, but many drugs are degrad...

00:46 The role of skull bone marrow in ageing During ageing, bone marrow in the skull becomes an increasingly important site of blood-cell production. This is in stark contrast to most bones where the ability of marrow to make blood and immune cells declines. Studies in mice and humans showed that ageing results in skull bone-marrow expanding, and in mice this marrow was more resistant to inflamma...

Samantha Harvey's Booker Prize shortlisted novel  Orbital  is set inside an International Space Station-like vessel circling 250 miles above Earth. It looks at a day-in-the-life of the crew, investigating the contrasts they experience during the 16 orbits they make around the planet, crossing continents, oceans and the line separating night and day. On the latest episode of  Nature...

00:46 Mitochondria divide their labour to help cells thrive Researchers have uncovered that mitochondria divide into two distinct forms when cells are starved, a finding that could help explain how some cancers thrive in hostile conditions. Mitochondria are cellular powerhouses, creating energy and vital metabolic molecules, but how they are able to do this when resources are limited has been a my...
