With the world looking likely to blow past the temperature targets laid out in the 2015 Paris climate agreement, a growing number of voices are saying that carbon removal technologies will be necessary if humanity is to achieve its long-term climate goals. If these approaches succeed, they could help nations and corporations to meet their climate commitments — and help the world to halt global warming.However, questions remain about the financial viability of these technologies, and whether they can live up to the hype.This is an audio version of our Feature: Three ways to cool Earth by pulling carbon from the sky Hosted on Acast.

00:45 Treating mosquitoes for malariaResearchers have developed two compounds that can kill malaria-causing parasites within mosquitoes, an approach they hope could help reduce transmission of the disease. The team showed that these compounds can be embedded into the plastics used to make bed nets, providing an alternative to insecticide-based malaria-control measures, which are losing efficacy in the face of increased resistance.Research article: Probst et al.10:42 Research HighlightsThe sunlight-powered device that can harvest drinkable water from desert air, and evidence that the world’s richest people are disproportionately responsible for climate impacts.Research Highlight: Atacama sunshine helps to pull water from thin airResearch Highlight: The world’s richest people have an outsized role in climate extremes13:02 The genetics that can lead to pregnancy lossResearchers have found specific genetic mutations that can lead to pregnancy loss. It’s known that errors, such as the duplication of chromosomes, can lead to nonviable pregnancies but less has been known about non-chromosomal genetic errors. The new work identifies DNA sequence changes that can lead to a non-viable pregnancy. This may offer clinicians the ability to screen embryos for these changes to help avoid pregnancy loss.Research article: Arnadottir et al.22:24 Briefing ChatBespoke CRISPR-based therapy treats baby boy with devastating genetic disease, and the ‘anti-spice’ compounds that can lower chillies’ heat.Nature: World’s first personalized CRISPR therapy given to baby with genetic diseaseNew Scientist: Chemists discover 'anti-spice' that could make chilli peppers less hotSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

00:46 An antimatter delivery van takes its first road tripResearchers have developed a portable antimatter containment device and tested it by putting it in a truck and driving it around CERN. Their system could represent a big step forward in efforts to take particles made at CERN’s ‘antimatter factory’ and transport them to other labs, something currently impossible due to antimatter being destroyed upon contact with matter. The team showed the feasibility of their approach by using the system to safely transport particles of matter and are now looking to adapt it to ferry antimatter particles.Research article: Leonhardt et al.11:45 Research HighlightsHow a tradition of female diving on a South Korean island might have shaped the genomes of the island’s population, and a poison-dart frog that curiously seems to be monogamous.Research Highlight: How Korea’s female divers have adapted to cold plungesResearch Highlight: A ‘hidden gem’ of the Amazon is a frog with odd habits13:46 The mathematics of a near-miss between black holesPhysicists have tackled a longstanding problem in physics — understanding how two black holes gravitationally interact as they fly past each other — which could help with future detections of the gravitational waves that would be created by these events. Rather than repeatedly running expensive computer simulations to approximate the answer to this problem, a team of theorists have come up with a mathematical formula to describe a black hole fly-by, which can be run in a matter of seconds. Their results could be used to identify the tell-tale signatures of these events when they actually occur.Research article: Driesse et al.22:10 Briefing ChatHow physicists turned lead into gold, for a microsecond and at tremendous cost, and the genetics of the skunk cabbage’s foul odour.Nature: Physicists turn lead into gold — for a fraction of a secondVideo: Scientists turn lead into goldNature: How skunk cabbages and other smelly plants brew their foul odourSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

00:46 How fishing activity altered the migration pattern of HerringSelective fishing of older herring has resulted in a large shift in the migration pattern of these fish, according to new research. For years, herring have visited sites on the south coast of Norway to spawn, but in 2020 a rapid shift was seen, with the fish instead visiting areas hundreds of kilometres to the north. Researchers have concluded that too many older fish have been removed from these waters, preventing the knowledge of the best spawning grounds being passed to younger, less experienced fish. This finding shows how human activity can affect animal migration, which could have serious consequences for the delicately balanced ecosystems built around them.Research article: Slotte et al.10:37 Research HighlightsArchaeologists have identified tools that the ancient Maya may have used for tattooing, and the self-assembling stable structures that may help ‘forever chemicals’ persist in nature.Research Highlight: Tattoo-making tools used by ancient Maya revealedResearch Highlight: ‘Forever’ molecules bunch themselves into cell-like structures13:02 How might AI companions affect users’ mental health?AI companions — apps where humans build relationships with computers — are hugely popular, with millions of people around the world using them.

Research shows that, over the past two decades, rates of mental illness have been increasing in adolescents in many countries. While some scientists point to soaring use of smartphones and social media as a key driver for this trend, others say the evidence does not show a large effect of these technologies on teenagers’ psychological health.At the heart of the dispute is a large, complex and often conflicting body of research that different researchers interpret in different ways. This has left parents unsure what to do.This is an audio version of our Feature: Do smartphones and social media really harm teens’ mental health?

00:27 Five people see ‘olo’, a brand-new colourUsing a laser system to activate specific eye cells, a team has allowed five study participants to perceive a vibrant blue-greenish hue well outside the natural range of colours seen by humans. Although the setup required to accomplish this feat is currently complicated, this finding could provide more understanding about how the brain perceives colour and could one day help boost the vision of people with colour blindness.Nature News: Brand-new colour created by tricking human eyes with laser08:30 US regulator greenlights pig-liver transplant trialThe US Food and Drug Administration has approved the first trial to test whether genetically modified pig livers can be used safely to treat people with organ failure. In the initial phase of the trial, four people with severe liver failure will be temporarily connected to an external pig liver that will filter their blood. Participants will then be monitored for a year for safety and changes in liver function. The organs have been genetically modified to make them more compatible with humans.Nature News: Pig livers for people: US regulator greenlights first safety trial14:08: A chunk of lab-grown chickenUsing a designer ‘circulatory system’, a team of researchers have created what they think is the largest piece of meat grown in the laboratory yet. One of the challenges to producing larger pieces of lab-grown meat has been providing cells with sufficient oxygen and nutrients, something the team’s new setup helps overcome. They used it to grow a chunk of chicken muscle about the size of a nugget, but multiple challenges remain before meat produced in this way could make it to market.Nature News: Winner, winner, lab-made dinner!

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. What’s in a name is a series exploring naming in science and how names impact the world. We look at whether the system of naming species remains in step with society, how the names of diseases can create stigma, and how the names chosen by scientists can help, or hinder, communication with the public.In episode three, we're looking at how the names chosen for concepts in physics can inadvertently send researchers down very specific research avenues while distracting them from others. In this podcast we hear five stories about the importance of names and how much can be lost in translation when physicists try and label the unknown.For a list of sources and music used, please visit the podcast show notes Hosted on Acast.

Many particle accelerators that power huge experiments like the Large Hadron Collider at CERN are radio-frequency accelerators, but they are large and limited in how strong their magnetic fields can be. The new work shows that accelerators that instead use plasma to accelerate particles could be a viable alternative and could be built at much smaller scales.Research article: Winkler et al.19:55 Briefing ChatA drug that makes blood poisonous to mosquitoes, and how an AI worked out how to solve key challenges in Minecraft by ‘imagining’ solutions.Science Alert: Drug For Rare Disease Turns Human Blood Into Mosquito PoisonNature: AI masters Minecraft: DeepMind program finds diamonds without being taughtVote for us in this year's Webby AwardsVote for How whales sing without drowning, an anatomical mystery solvedVote for What's in a name: Should offensive species names be changed?

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 study analysing data from thousands of research articles has shown that the human impacts on biodiversity are large but are in some cases context dependent. The new study reveals that at larger scales, communities of living things are becoming more similar due to human influence, but at the smaller scale they are becoming more different. "These are generally unwanted effects on biodiversity," says study author Florian Altermatt, "this is one more very strong argument that stopping and reducing these pressures to halt and reverse biodiversity declines is needed."Research article: Keck et al.21:45 Briefing ChatHow a proposed green-energy facility in Chile could increase light pollution at one of the world’s most powerful telescopes, and how a calving Antarctic iceberg revealed an unseen aquatic ecosystem.Nature: Light pollution threatens fleet of world-class telescopes in Atacama DesertScientific American: Stunning Antarctic Sea Creatures Discovered after Iceberg Breaks AwaySubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
