00:46 Millimetre-sized pacemaker fits inside syringeResearchers have developed a tiny, temporary pacemaker that dissolves when no longer needed, helping to overcome some of the challenges associated with current devices. Temporary pacemakers are often required after heart surgery but implanting them can require invasive procedures. This new device is injectable, requires no external power and is controlled using light shone through the skin. The tiny pacemaker has shown promise in animal and heart models, and the team think it could also be used in other situations where electrical stimulation is needed, like the brain.Research Article: Zhang et al.08:19 Research HighlightsMeasurements show that global warming is causing lakes to lose their oxygen, and a massive, 30-year analysis showing that a diet of plant-rich foods is associated with healthy ageingResearch Highlight: Life-giving oxygen is wafting out of lakes worldwideResearch Highlight: The best foods for healthy ageing ― and the worst10:2

With money pouring in and an unprecedented level of public attention and excitement, scientists are publishing a steady stream of papers on ways to measure how rapidly a person’s body is declining.However, there are mixed feelings of enthusiasm and apprehension among researchers about efforts to develop tests that measure the impact of ageing on the body, as they are often interpreted and presented without a full reckoning of the uncertainties that plague them.This is an audio version of our Feature: How quickly are you ageing?

In this episode:00:46 Newly discovered molecule shows potent antibiotic activityResearchers have identified a new molecule with antibiotic activity against a range of disease-causing bacteria, including those resistant to existing drugs. The new molecule — isolated from soil samples taken from a laboratory technician’s garden — is called lariocidin due to its lasso-shaped structure. The team say that in addition to its potent antibiotic activity, the molecule also shows low toxicity towards human cells, making it a promising molecule in the fight against drug-resistant infections.Research Article: Jangra et al.09:36 Research HighlightsA reduction in ships' sulfur emissions linked to a steep drop in thunderclouds, and the epic sea-voyage that let iguanas reach Fiji.Research Highlight: Ship-pollution cuts have an electrifying effect: less lightning at seaResearch Highlight: Iguanas reached Fiji by floating 8,000 kilometres across the sea13:54 Assessing the nuances of humans’ biodiversity impactsA huge stud

00:46 Microsatellite makes messaging secureA tiny satellite has enabled quantum-encrypted information to be sent between China and South Africa, the farthest distance yet achieved for quantum communication. Using a laser-based system, a team in the city of Hefei was able to beam a ‘secret key’ encoded in quantum states of photons, to their colleagues over 12,000 km away. This key allowed scrambled messages to be decrypted — including one containing a picture of the Great Wall of China. The team’s system is drastically smaller and cheaper that previous attempts, and they think it represents a big step towards the creation of a global network of secure, quantum communication.Research Article: Li et al.News: Mini-satellite paves the way for quantum messaging anywhere on Earth09:53 Research HighlightsHow storms known as ‘atmospheric rivers’ could replenish Greenland’s ice, and a prosthetic hand that can distinguish objects by touch almost as well as a human.Research Highlight: Mega-storm dumps 11 b

00:46 2D metals made using sapphire pressTaking inspiration from industrial forging, researchers have demonstrated a way to squeeze molten metals into atomically-thin layers, creating relatively large flakes of 2D metals. Using a hydraulic press containing two sapphire anvils, a team was able to create sub-nanometer thick sheets of different metals — these sheets had diameters exceeding 0.1 mm, orders of magnitude larger than other methods have achieved. 2D metals have been theorized to possess several useful properties not seen in their larger, 3D counterparts, but have been difficult to make at scale, something this method may help overcome.Research Article: Zhao et al.News and Views: Metals squeezed to thickness of just two atoms09:36 Research HighlightsThe discovery of ancient puppets on remains of a large pyramid offers a glimpse into rituals in Mesoamerica, and how the presence of a certain pattern of sleep brainwaves might help predict which people will recover from an unresponsive state.Rese

00:46 Ancient humans made bone tools 1.5 million years agoA 1.5-million-year-old cache of animal-bone tools reveals that ancient humans systematically crafted with this material much earlier than previously thought. Researchers uncovered 27 bone artefacts in Tanzania honed into sharp tools almost 40 cm long. This discovery pushes back the dedicated manufacture of bone tools by around a million years and could have helped these early humans develop new kinds of technology. “This raises a lot of interesting questions,” says study author Ignacio de la Torre.Research Article: de la Torre et al.09:11 Research HighlightsCane toads’ remarkable homing abilities, and evidence that the block of rock that makes up southern Tibet originated in what is now Australia.Research Highlight: Take me home, country toadsResearch Highlight: Lhasa′s rocks reveal an Australian birthplace11:45 A trove of antibacterial molecules hidden in human proteinsTo help protect against infection, cells in the body will selectivel

Over the past two decades, research has emerged showing that opportunities for risky play are crucial for children's healthy physical, mental and emotional development. However, because play is inherently free-form it has been difficult to study. Now, scientists are using innovative approaches, including virtual reality, to probe the benefits of risky play, and how best to promote it.This is an audio version of our Feature: Why kids need to take more risks — science reveals the benefits of wild, free play Hosted on Acast.

00:47 A ‘smart’ way to quickly detect cardiac arrestGoogle researchers have developed an AI for a smartwatch that will call for help if its wearer is having a cardiac arrest. Trained, in part, on data gained when patients had their hearts deliberately stopped during a medical procedure, the team’s machine learning algorithm can automatically detect the telltale signs of cardiac arrest. The team think this system could save lives, although more testing is required. "Our hope is that as these capabilities expand it provides a new way to keep people safer,” says Jake Sunshine, one of the researchers behind the study.Research Article: Shah et al.09:15 Research HighlightsEvidence that a low dose of yellow fever vaccine might be enough to provide lasting immunity, and the odd umbrella-shaped tree fossil that suggests that early plants may have been more complex than previously thought.Research Article: Kimathi et al.Research Article: Gastaldo et al.11:10 Briefing ChatMicrosoft’s new AI that helps cre

01:14 A simple switch to reduce racist ratingsA 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 and got paid less than their white counterparts. Through follow up studies the authors also showed that the five-star system allowed people to impart their personal opinions, whereas a thumbs up or down just focused them on whether a job was good or bad. The team hopes this could be an easy-to-implement shift to tackle racial discrimination.Research Article: Botelho et al.News and Views: Racial bias eliminated when ratings switch from five stars to thumbs up or down11:24 Research HighlightsExperimental evidence that cockatoos like flavouring their food, and the harsh climate of sixteenth century Transylvania.R

In this episode:00:45 An elusive, cosmic neutrino with a record-breaking energyAn 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. The team hopes that further study and future detections will help reveal the secrets of high-energy phenomena like supernovae.Research Article: The KM3NeT Collaboration11:34 Research HighlightsHow bonobos adjust their communication to account for what other individuals know, and the discovery of a huge collection of beads adorning the attire of the powerful Copper Age women in Spain.Research Highlight: Bonobos know when you’re in the know ― and when you’re notResearch Highlight: Record-setting trove of buried beads speaks to power of ancient women14:15 US judge puts NIH grant cuts on holdA judge has block

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 names impact the world — whether the system of naming species remains in step with society, how the names of diseases can create stigma, or even how the names of scientific concepts can drive the direction of research itself.In episode two, we're looking at how the names chosen by scientists help, or hinder, communication with the public.Well chosen names can quickly convey scientific concepts or health messages — in emergency situations they can even save lives. We'll hear how the systems of naming tropical storms and Covid-19 variants came to be, and how they took different approaches to achieve the same outcome.We'l

In this episode:00:45 How arithmetic skills don’t transfer between applied and academic environmentsMathematics 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 arithmetic problems, they struggled to solve problems typically used in schools. The reverse was seen for children enrolled in schools with no market-selling experience. The authors hope this finding could help adjust teaching curricula and bridge the gap between intuitive and formal maths.Research Article: Banerjee et al.12:38 Research HighlightsWolverine populations rebound in Sweden and Norway, and why wobbly arrows launch faster than rigid ones.Research Highlight: Who’s the new furry neighbour?

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 their AIs.This is an audio version of our Feature: The AI revolution is running out of data.

In this episode:00:46 Evidence of ancient brine reveals Bennu’s watery pastAnalysis 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 suggest that brines may have been an important place where pre-biotic molecules were formed. As brines are found throughout the Solar System, this finding raises questions about whether similar molecules will be found in places like Jupiter’s moon Europa.Research Article: McCoy et al.Research Article: Glavin et al.News: Asteroid fragments upend theory of how life on Earth bloomed14:22 Research HighlightsHow seaweed farms could capture carbon, and why chimps follow each other to the bathroom.Research Highlight: Seaweed farms dish up climate benefitsResearch Highlight: All together now: chimps engage i

00:56 How the paths to professorship varyA 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 in this study could help institutions adjust their hiring policies to create a more diverse science workforce.Research Article: Lim et al.News: Want to become a professor?

00:46 Designing new antivenoms to treat snakebitesResearchers 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 settings where most bites occur. The computer-aided approach allowed researchers to design two proteins that provided near total protection against individual snake toxins in mouse experiments. While limited in scope, the team behind the work believe these results demonstrate the promise of the approach in designing effective and cheaper treatments for use in humans.Research Article: Vázquez Torres et al.11:28 Research HighlightsHow male wasp spiders use hairs on their legs to sniff out mates, and how noradrenaline drives waves of cleansing fluid through the brain.Research Highlight: ​​​​​​​Male spiders smell with their le
