AI-enhanced night-vision lets users see in the dark
26/07/2023 Duration: 21minIn 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 imaging enables day-like visibility at night09:27 Research HighlightsBenjamin Franklin’s anti-counterfeiting money printing techniques, and how much snow is on top of Mount Everest really?Research Highlight: Ben Franklin: founding father of anti-counterfeiting techniquesResearch Highlight: How much snow is on Mount Everest?

Disrupting snail food-chain curbs parasitic disease in Senegal
19/07/2023 Duration: 24minIn 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 improve health and the economy.Research article: Rohr et al.News and Views: A sustainable way to control the parasitic disease schistosomiasis12:03 Research HighlightsHow artificial intelligence can predict the art that people will find memorable, and the protein-based, shock-absorbing gel that can stop projectiles in their tracks.Research Highlight: Memorable artworks are easy to predictResearch Hi

ChatGPT can write a paper in an hour — but there are downsides
12/07/2023 Duration: 14minIn this episode:00:23 Using ChatGPT to generate a research paper from scratchA 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 speed up research, it is still unclear what role they should play in research.Nature News: Scientists used ChatGPT to generate an entire paper from scratch — but is it any good?06:28 Last week saw the world’s hottest day on record – twiceOn Monday last week the average worldwide temperature reached 17.01 °C, beating a record set in 2016. Then, on Tuesday that record was broken again, as average temperatures hit 17.18 °C. Further record-breaking days may follow this year as a result of climate change, and the arrival of the El Niño weather phenomenon, which is expected to strengthen in the coming months.Bloomberg:

Even a 'minimal cell' can grow stronger, thanks to evolution
05/07/2023 Duration: 29minIn 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 offspring, and how microwaving plastic containers can release microplastic particles.Research Highlight: Dolphin mums whistle ‘baby talk’ with their calvesResearch Highlight: What happens when you microwave that plastic bowl?12:18 The first hints of giant gravitational wavesGravitational waves were first detected in 2015, when two black holes collided — sending ripples in space-time across the Univers

Do octopuses dream? Neural activity resembles human sleep stages
28/06/2023 Duration: 30minIn 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
21/06/2023 Duration: 29minIn 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 deep into the lungs, and why artificial lights could dazzle glow worms into extinction.Research Highlight: Flu virus hitches a ride with haze particles deep into the lungResearch Highlight: Glow-worms’ ‘come-hither’ signals are lost in the glare of human lights10:10 Engineering synthetic cartilageThe cartilage in our joints is able to withstand and dissipate a lifetime of impacts, protecting

What IBM's result means for quantum computing
14/06/2023 Duration: 29minIn 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 the near future.Nature News: IBM quantum computer passes calculation milestoneResearch article: Kim et al.News and Views: Quantum computer scales up by mitigating errors10:11 Research HighlightsHow some bacteria turned their defences into weapons, and a forecast of how quickly arctic sea ice will disappear.Research Highlight: Cholera bacteria turn slime into an offensive weaponResearch Highlight: Th

A brain circuit for infanticide, in mice
07/06/2023 Duration: 31minIn 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 between neural circuits for infanticide and maternal-care behaviours08:11 Research HighlightsThe cyclone raging at the north pole of Uranus, and the ants that build landmarks to help them find their way home.Research Highlight: A storm is whirling atop UranusResearch Highlight: These hardy ants build their own landmarks in the desert10:52 Getting to the source of fast solar windThe sun produces

AI identifies gene interactions to speed up search for treatment targets
31/05/2023 Duration: 21minIn 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 targets.Research article: Theodoris et al.09:08 Research HighlightsMicrobes that can break down persistent ‘forever chemicals’, and why intermolecular distances are the key to keeping gummy sweets chewy.Research Highlight: Microbes take the ‘forever’ out of ‘forever chemicals’Research Highlight: Better gummy sweets are within reach, thanks to physics12:06 Briefing ChatWe discuss some highlights fr

‘Tree islands’ give oil-palm plantation a biodiversity boost
24/05/2023 Duration: 23minIn 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 Research HighlightsThe oldest identified ‘blueprints’ depict vast hunting traps with extraordinary precision, and fossil evidence that pliosaurs swimming the Jurassic seas may have been as big as whales.Research Highlight: Oldest known ‘blueprints’ aided human hunters 9,000 years agoResearch Highlight: This gigantic toothy reptile terrorized the Jurassic oceans12:08 Briefing ChatWe discuss some

Nature's Take: Can Registered Reports help tackle publication bias?
12/05/2023 Duration: 26minMany 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 review process in two, first critically assessing the methodology of a research study before data is collected, and again when the results are found. The idea being to encourage robust research regardless of the outcome.In this episode of Nature's Take we discuss Nature's recent adoption of the format, the pros and cons of Registered Reports, and what more needs to be done to tackle publication bias.

‘Pangenome’ aims to capture the breadth of human diversity
10/05/2023 Duration: 21minIn this episode:00:45 Making a more diverse human genomeThe 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 human populations. To address this, a consortium of researchers have published the first draft of a ‘pangenome’, which combines the genomes of 47 genetically diverse individuals. This draft provides a more complete picture of the human genome, and is the starting point for a project that aims to include sequences from 350 individuals.Research article: Liao et al.
