A mussel-inspired glue for more sustainable sticking
In this episode:00:46 A sustainably-sourced, super-strong adhesiveThe modern world is held together by adhesives, but these fossil-fuel derived materials come at an environmental cost. To overcome this, a team have developed a soya-oil based adhesive, which also takes inspiration from the proteins that marine animals like mussels use to stick firmly to rocks. The researchers say their glue is strong, reversible, and less carbon intensive to produce than existing adhesives.Research article: Westerman et al.07:43 Research HighlightsWhy chemicals derived from wood could be sustainable alternatives to a common plastic building block, and how historical accounts helped researchers estimate the brightness of a 1859 solar flare.Research Highlight: Wood component yields useful plastics — without the health risksResearch Highlight: A historic solar flare’s huge intensity is revealed by new tools10:08 New insights into childhood stunting and wastingAround the world, millions of children are affected by malnutrition, which can result in stunting or wasting, both associated with serious health issues. Despite a widespread recognition of the seriousness of stunting and wasting, there are still questions about their extent, causes and consequences. To answer these, a team have pooled data from previous studies, and show that nutritional interventions targeting the earliest years of life could have the greatest impact.Research article: Benjamin-Chung et al.Research article: Mertens et al.Research article: Mertens et al.Nature Collection: Progress towards the Sustainable Development Goals20:29 Briefing ChatThis time, what rejoining the Horizon Europe research-funding programme means for UK research, and the 1.4-million-year-old stone balls that are mystifying scientists.Nature News: Scientists celebrate as UK rejoins Horizon Europe research programmeScience: Were these stone balls made by ancient human relatives trying to perfect the sphere?Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

In this episode:00:47 First observation of oxygen 28Oxygen 28 is an isotope of oxygen with 20 neutrons and eight protons. This strange isotope has long been sought after by physicists, as its proposed unusual properties would allow them to put their theories of how atomic nuclei work to the test. Now, after decades of experiments physicists believe they have observed oxygen 28. The observations are at odds with theory predictions, so they imply that there’s a lot more physicists don’t know about the forces that hold atomic nuclei together.Research article: Kondo et al.News and Views: Heaviest oxygen isotope is found to be unbound10:06 Research HighlightsHow venus fly traps can protect themselves from wildfires, and a ball-point pen that can ‘write’ LEDs.Research Highlight: Venus flytraps shut their traps when flames approachResearch Highlight: A rainbow of LEDs adorns objects at the stroke of a pen12:39 An AI for Drone RacingAIs have been beating humans at games for years, but in these cases the AI has always trained in exactly the same conditions in which it competes. In chess for example, the board can be simulated exactly. Now though, researchers have demonstrated an AI that can beat humans in a place where simulation can only take you so far, the real world. The Swift AI system is able to race drones against champion-level humans, and beat them most of the time. The researchers hope this research can help improve the efficiency of drones in general.Research article: Kaufmann et al.News and Views: Drone-racing champions outpaced by AIVideo: AI finally beats humans at a real-life sport - drone racing19:51 Briefing ChatThis time, the Indian Space Research Organization’s successful moon landing, and the low level of support offered to researchers whose first language isn’t English by journals.Nature News: India lands on the Moon!

Audio long read: Medicine is plagued by untrustworthy clinical trials. How many studies are faked or flawed?
Investigations suggest that, in some fields, at least one-quarter of clinical trials might be problematic or even entirely made up. Faked or unreliable trials are dangerous, as they could end up being included in the reviews that help inform clinical treatments. However, the extent of the problem in unclear, and many researchers urge stronger scrutiny.This is an audio version of our Feature: Medicine is plagued by untrustworthy clinical trials.

Brain-reading implants turn thoughts into speech
In this episode:00:47 The brain-computer interfaces that help restore communicationPeople with certain neurological conditions can lose the ability to speak as a result of facial paralysis. This week, two teams demonstrate the potential of devices called brain-computer interfaces to help people in these situations communicate. These interfaces work by identifying the brain activity associated with the intent to say words, and converting this activity into speech-related outputs, such as text or audio. Both devices show marked improvements compared with previous interfaces, and show that the technology could represent a way to help restore communication to people with severe paralysis.Research article: Metzger et al.Research article: Willett et al.News and Views: Brain implants that enable speech pass performance milestones11:46 Research HighlightsHow wind-tunnel experiments could help athletes run the fastest marathon ever, and an analysis that could help explain why birds are the colours they are.Research Highlight: Physicists find a way to set a new marathon recordResearch Highlight: Which birds are drab and which dazzle?

But it’s unknown how much the trees can endure before their leaves start to die. A team has combined multiple data sources to try and answer this question, and suggest that a warming of 3.9 °C would lead to many leaves reaching a tipping point at which photosynthesis breaks down. This scenario would likely cause significant damage to these ecosystems’ role in vital carbon storage and as homes to significant biodiversity.Research article: Doughty et al.21:01 Briefing ChatThis time, a reexamination of Ötzi the iceman’s DNA suggests he had a different appearance, and the failure of a Russian mission to the moon.Nature News: Ötzi the Iceman has a new look: balding and dark-skinnedNature News: Russian Moon lander crash — what happened, and what’s next?Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

Fruit flies' ability to sense magnetic fields thrown into doubt
In this episode:00:49 The search for animals’ magnetic sense sufferers a potential setbackExactly how animals sense Earth’s magnetic field has long eluded researchers. To understand it, many have turned to the fly model Drosophila melanogaster, long thought to be able to detect magnetic fields. However, a recent Nature paper has raised questions about this ability, a finding that could have repercussions for scientists’ efforts to understand the mechanism behind magnetic sensing, one of the biggest questions in sensory biology.Research article: Bassetto et al.News & Views: Replication study casts doubt on magnetic sensing in flies10:53 Research HighlightsThe world’s first filter feeder, and human-caused climate change in the Bronze Age.Research Highlight: This ancient reptile wanted to be a whaleResearch Highlight: Bronze Age deforestation changed Europe’s climate13:03 An iconic observatory shuts downThis week the famed Arecibo Observatory in Puerto Rico shut down. The facility’s main telescope collapsed in 2020 and the site has since been battered by storms and pandemic-related shutdowns. Now, with funding exhausted and no clear plan in place, scientists are wondering what will become of the site.Nature News: Closing down an icon: will Arecibo Observatory ever do science again?20:28 Briefing ChatThis time, the Standard Model of physics still isn't dead according to new measurements of muons' magnetic moment, and finding the most diverse habitat on Earth under your feet.Nature News: Dreams of new physics fade with latest muon magnetism resultThe Guardian: More than half of Earth’s species live in the soil, study findsSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

How welcome are refugees in Europe? A giant study has some answers
In this episode:00:46 A measure of refugees’ welcome in EuropeWith repeated humanitarian crises displacing millions of people, researchers have been considering how this might affect acceptance of refugees. Will some refugees be more welcome than others? Will continued movements erode support for refugees overall? To answer these questions, a huge study looks at the attitudes of 33,000 people from 15 European countries towards refugees. They find that overall support for refugees has slightly increased, although some characteristics, such as ability to speak the language of the country they’re settling in, are preferred. They hope this research will help policymakers to respond to stresses on the asylum system.Research article: Bansak et al.11:26 Research HighlightsThe unusual feeding grounds of the pygmy right whale, and the JWST spots a possible quasar from the early Universe.Research Highlight: An enigmatic little whale’s habits, from its own mouthResearch Highlight: JWST spots what could be a quasar from the early Universe13:44 Briefing ChatWe discuss some highlights from the Nature Briefing.
