In the latest episode of Nature hits the books , physicist Athene Donald joins us to discuss her book Not just for the boys, why we need more women in science. We discuss how science has historically excluded women, the barriers to entry and retention that remain prevalent, and what could be done to improve the situation for female scientists today. Not Just for the Boys: Why We Need More Women in...

Neuroscientists are creating more naturalistic experiments that they hope will provide a more nuanced understanding of animal — and human — behaviour. These set-ups differ from the classic laboratory experiments that have been used for decades, and may help in the understanding of behaviours such as escaping a predator or finding scarce food. By studying these natural actions, scientists are hopin...

In this episode: How tweaking social media algorithms affects polarization Societies are becoming increasingly polarized, with people reportedly shunning those with differing political views. Social media is often thought to be exacerbating these divides, by creating echo chambers and filtering out dissimilar views. Many hoped that tweaking the algorithms that drive these platforms could reduce po...

In this episode: 00:46 How to see in the dark like it’s daytime There are many methods for better night-vision, but often these rely on enhancing light, which may not be present, or using devices which can interfere with one another. One alternative solution is to use heat, but such infrared sensors struggle to distinguish between different objects. To overcome this, researchers have now combined...

In this episode: 00:45 A sustainable solution for schistosomiasis control Schistosomiasis is a serious parasitic disease that affects millions of people, who become infected when they come into contact with contaminated water. To prevent the spread and reinfection of this disease, researchers trialled an environmental intervention that removed plants from lakes in Senegal. These plants act as food...

In this episode: 00:23 Using ChatGPT to generate a research paper from scratch A pair of scientists have produced a research paper in less than an hour with the help of the generative artificial intelligence (AI) ChatGPT. The aim of this exercise was to explore the technology’s ability to act as a research ‘co-pilot’ and spark debate about its use. While AI tools like ChatGPT have the potential to...

In this episode: 00:46 The effects of evolution on a minimal genome In 2016, researchers created a ‘minimal cell’ bacterium with a genome that only contains genes essential for the organism's survival. Any mutation in these genes could be fatal, so it was unclear whether there could be scope for evolution. But now, a team has grown this bacterium through 2,000 generations and shown that it does ha...

In the past two years, there has been an explosion in the number of papers published relating to 'skeletal editing', a technique that allows chemists to precisely edit a molecule by deleting, adding or swapping single atoms in its core. Although many of these methods are early in development, researchers hope skeletal editing could revolutionize how organic chemists design molecules, dramatically...

In this episode: 00:46 Inside the brains of sleeping octopuses Researchers have probed the brains of octopuses and confirmed previous reports suggesting that these invertebrates have a two-stage sleep cycle similar to that seen in many vertebrates. The team suggests this system may have evolved independently in the two groups, as there are millions of years of evolutionary history between them. Ho...

In this episode: 00:45 Why losing the Y chromosome makes bladder cancer more aggressive Loss of the Y chromosome in bladder cancer cells is associated with increased severity of disease, but the reasons behind this have been unclear. Now researchers show that the loss of this chromosome helps tumour cells evade the immune system. However, this mechanism also makes the cells more vulnerable to cert...

In this episode: 00:47 How to make quantum computers ready for real world applications Quantum computers have long held the promise of being able to perform tasks that classical computers can’t. However, despite this promise, there have been few applications that can only be accomplished by a quantum computer. Now though, researchers show that a quantum computer can resolve a physics problem conce...

In this episode: 00:46 The mouse brain circuit controlling infanticidal behaviour In mammals, infanticide is a relatively common behaviour, but not a default one. For example, virgin female mice will often kill young produced by other females, but this behaviour disappears when they become mothers themselves. To understand this switch, researchers have identified a brain circuit associated with in...

In this episode: 00:46 An AI that predicts gene interactions Mapping the network of genes that control cellular processes can be difficult to do when gene-expression data is sparse, such as in rare diseases or those affecting tissues that are hard to clinically sample. To overcome this, a team has developed an artificial intelligence system trained on a large, general dataset, and used it to make...

Shocked by the impact of online misinformation surrounding the COVID-19 pandemic, several researchers are launching efforts to survey scientists’ thinking on issues from vaccine safety to climate change. They hope that their projects will make scientific debate, and degrees of consensus, more visible and transparent, benefiting public conversation and policymaking. However, others suggest that the...

In this episode: 00:45 Tree islands bring biodiversity benefits for oil-palm plantation Global demand for palm oil has resulted in huge expansion of the palm plantations needed to produce it, causing widespread tropical deforestation and species loss. To address this, researchers planted islands of native trees among the palms in a large plantation, and showed that this approach increases ecosyste...

In this episode: 00:46 What JWST has revealed about an ancient galaxy Researchers have pointed the James Webb Space Telescope (JWST) at JD1, one of the universe's most distant known galaxies. The power of JWST has filled in some of the gaps in what was known about the galaxy, giving greater insight into its age, structure and composition. The team behind the work hope that learning more about how...

Many researchers have been critical of the biases that the publication process can introduce into science. For example, they argue that a focus on publishing interesting or significant results can give a false impression of what broader research is finding about a particular field. To tackle this, some scientists have championed the publication of Registered Reports. These articles split the peer...

In this episode: 00:45 Making a more diverse human genome The first draft of the human genome ushered in a new era of genetics research. Since its publication, researchers have constructed ever more accurate ‘reference genomes’ – baselines against which others are compared. But these are based on the DNA of a small number of people, and don’t represent the genetic variation known to exist across h...

In this episode: 00:47 A focus on women’s health Nature ’s Kerri Smith and Heidi Ledford join us to discuss two Features published in Nature looking at topics surrounding women’s health. The first looks at efforts to understand how menopause affects brain health, while the second takes a deep-dive into research funding and shows how conditions affecting women more than men receive less money. Feat...

Last year, researchers announced that the Alzheimer’s drug lecanemab lowered the amount of amyloid protein plaques associated with the disease in the brains of participants in a clinical trial, and slowed their cognitive decline. Now, researchers are looking to drug combinations, vaccines and gene therapy to tackle different stages of the disease, as they forge the next generation of treatments fo...

In this episode: 00:57 Franklin’s real role When it comes to the structure of DNA, everyone thinks they know Rosalind Franklin’s role in its discovery. The story goes that her crucial data was taken by James Watson without her knowledge, helping him and Francis Crick solve the structure. However, new evidence has revealed that this wasn’t really the case. Rosalind Franklin was not a ‘wronged heroi...

In this episode: 00:45 A new method to break down plastic polymers Plastic waste is an enormous problem, with much of it being incinerated or ending up in landfill. One way to give plastics another life is to break them down into their individual components using heat, but this method yields low amounts of usable product. Now, a team demonstrates a proof-of-concept method of heating that wicks the...

In the latest episode of Nature hits the books , psychologist Sander van der Linden joins us to discuss his new book Foolproof , which focuses on misinformation and what can be done to prevent people being duped, particularly by the falsehoods found online. We discuss how misinformation messages are crafted, why they can be hard to shake once someone is exposed, and how Star Wars : Episode 3 helpe...

00:44 The unusual receptors that let octopuses hunt by touch Researchers have shown that the suckers of octopuses are covered with specialised receptors that allow them to taste by touching things. Similar receptors are also found in squid, but there are differences that mirror differences in the animals’ hunting behaviours; while octopuses feel for their prey, squid pull things towards themselves...

00:46 A pair of supermassive black holes in the distant universe Supermassive black holes are found at the centre of galaxies across the universe. But observations of galaxies with more than one – caused by the merging of two galaxies – have been rare. Now, researchers have combined data from a number of telescopes and satellites, to reveal a pair of supermassive blackholes farther from Earth than...
