Audio long read: Lab mice go wild — making experiments more natural in order to decode the brain
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 hoping to glean lessons about the brain and behaviour that are more holistic and more relevant to everyday activity than ever before.This is an audio version of our Feature: Lab mice go wild: making experiments more natural in order...

Facebook ‘echo chamber’ has little impact on polarized views, according to study
In this episode:How tweaking social media algorithms affects polarizationSocieties 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 polarization. But, a group of studies show that such changes have little to no affect on polarization, implying that solutions to this issue are trickier than previously thought.Research Article: Nyhan et al.News and Views: Influence ...

AI-enhanced night-vision lets users see in the dark
In this episode:00:46 How to see in the dark like it’s daytimeThere 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 such sensors with machine learning algorithms to make a system that grants day-like night-vision. They hope it will be useful in technologies such as self-driving cars.Research article: Bao et al.News and Views: Heat-assisted imag...

Disrupting snail food-chain curbs parasitic disease in Senegal
In this episode:00:45 A sustainable solution for schistosomiasis controlSchistosomiasis 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 for freshwater snails – intermediate hosts for the disease. Results showed that this reduced disease levels, and that the plants could be composted to increase agricultural yields, suggesting this approach could be used to improv...

Even a 'minimal cell' can grow stronger, thanks to evolution
In this episode:00:46 The effects of evolution on a minimal genomeIn 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 have the ability to evolve and can recover from some of the fitness costs associated with its streamlined genome.Research article: Moger-Reischer et al.09:21 Research HighlightsDolphins use ‘baby talk’ when talking to their of...

Audio long read: ‘Almost magical’ — chemists can now move single atoms in and out of a molecule’s core
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 speeding up the drug-discovery process.This is an audio version of our Feature: ‘Almost magical’: chemists can now move single atoms in and out of a molecule’s core Hosted on Acast.

Do octopuses dream? Neural activity resembles human sleep stages
In this episode:00:46 Inside the brains of sleeping octopusesResearchers 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. However, despite its presumed importance, it is a mystery why this system exists at all.Research article: Pophale et al.Nature Video: Do octopuses dream?

Why bladder cancer cells that shed their Y chromosome become more aggressive
In this episode:00:45 Why losing the Y chromosome makes bladder cancer more aggressiveLoss 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 certain chemotherapy treatments, and the researchers hope their findings could help improve outcomes for patients in the future.Research article: Abdel-Hafiz et al.07:30 Research HighlightsHow pollution particles ferry influenza virus d...

What IBM's result means for quantum computing
In this episode:00:47 How to make quantum computers ready for real world applicationsQuantum 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 concerning the orientation of quantum particles in a 2D material, which is difficult to accomplish with a ‘regular’ machine. They hope that this shows how quantum computers could be applied in real world research applications in th...

A brain circuit for infanticide, in mice
In this episode:00:46 The mouse brain circuit controlling infanticidal behaviourIn 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 infanticidal behaviour that gets switched off after mice give birth. They hope that by better understanding this circuit it could inform why animals engage in such behaviours.Research article: Mei et al.Research Briefing: A battle bet...

AI identifies gene interactions to speed up search for treatment targets
In this episode:00:46 An AI that predicts gene interactionsMapping 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 predictions about gene interactions in data-limited situations. As a test-case they look at the heart condition cardiomyopathy, and show that the system can identify potential interactions that could represent new therapeutic target...

‘Tree islands’ give oil-palm plantation a biodiversity boost
In this episode:00:45 Tree islands bring biodiversity benefits for oil-palm plantationGlobal 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 ecosystem health, without affecting crop yields. The team say that while protecting existing tropical rainforests should remain a priority, tree islands represent a promising way to restore ecosystems.Research article: Zemp et al.09:42 Rese...
