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.

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.

However, this system is not without its issues. For example, there has been much debate around whether species with names considered offensive — such as those named after historical racists — should be changed, and what rule changes need to be made to allow this to happen.We speak to researchers about the history of this naming system, how it's applied and how it might evolve in the face of growing pressures.SourcesFor a full list of sources, please visit https://www.nature.com/articles/d41586-024-04200-9Music creditsPremiumaudio/Pond5Alon Marcus/Pond5Groove Committee/Pond5Opcono/Pond5Erik Mcnerny/Pond5Earless Pierre/Pond5Richard Smithson/Triple Scoop Music/Getty Images​​​​​​​Douglas Romayne/Triple Scoop Music/Getty ImagesSound effects via Pond5Thick-billed Longspur/​​​​​​​Andrew Spencer via ​​​​​​​CC BY-NC-ND 2.5 Hosted on Acast.

00:45 A potential treatment for pre-eclampsiaResearchers have shown in mice experiments that an mRNA-based therapy can reverse the underlying causes of pre-eclampsia, a deadly complication of pregnancy for which treatment options are limited. Inspired by the success of mRNA vaccines, the team behind the work designed a method to deliver the genomic instructions for a blood-vessel growth factor directly into mouse placentas. This stimulated the production of extra blood vessels reducing the very high-blood pressure associated with the condition. Pre-eclampsia causes 15% of maternal deaths and 25% of foetal and newborn deaths worldwide and although the work is early and human trials will be required, the team hope that this work demonstrates the potential of using this approach to treat pre-eclampsia.Research Article: Swingle et al.11:00 Research HighlightsStacks of, mass-produced bowls suggest that people founded, but then abandoned an ancient Mesopotamian civilization, and analysis of Venus's gases suggests that the planet was always dry.Research Highlight: Ancient stacks of dishes tell tale of society's dissolutionResearch Highlight: Has Venus ever had an ocean?

Creating these switches has been a long-term goal for synthetic biologists — especially a group of proteins called G-protein-coupled receptors that already control many cellular processes. However, engineering these proteins has been challenging, as modifications can ruin their function. Instead, the team added another molecular component that blocked the receptors activity, but could be removed in response to specific signals. This allowed the researchers to activate these receptors on command, potentially opening up a myriad of new ways to control cell behaviour, such as controlling when neurons fire.Research Article: Kalogriopoulos et al.19:35 Google reaches a milestone in quantum computingA team at Google has shown it is possible to create a quantum computer that becomes more accurate as it scales up, a goal researchers have been trying to achieve for decades.

The team showed that by increasing the quality of all the components in a quantum computer they could create a system with fewer errors, and that this trend of improvement continued as the system became larger.

Why these animals rose to dominance has been unclear, with one theory proposing that a chance event wiped out other species, whereas another suggests that dinosaurs had adaptations that better allowed them to thrive. By analysing over 500 vomit and faeces fossils, researchers have better identified what dinosaurs ate, and their interactions with other animals.

00:45 A squid-inspired device for needle-free drug deliveryInspired by squids' ability to shoot ink, a team of researchers have developed swallowable devices that can deliver tiny jets of drugs directly into the gut lining, circumventing the need for needles. Previous studies have shown that most people prefer to take medication in pill form, rather than as an injection, but many drugs are degraded as they pass through the digestive system. The team's new swallowable devices overcome this issue, and deliver drugs directly to where they need to be. So far, this approach has shown efficacy in animal models, but more work needs to be done to ensure their safety in humans.Research Article: Arrick et al.10:50 Research HighlightsThe largest ‘terror bird' fossil ever found, and a simple solution to help prevent premature births.Research Highlight: Huge carnivorous ‘terror bird' rivalled the giant panda in sizeResearch Highlight: Reducing pregnancy risk could be as easy as chewing gum12:52 A milder way to break down ‘forever chemicals'.Two papers describe how light-activated catalysts could be used to break down toxic ‘forever chemicals', hinting at a new way to clean up pollution caused by these persistent compounds. Forever chemicals contain multiple carbon-fluorine bonds that give them useful physical properties, but these bonds are some of the strongest in organic chemistry, making these compounds energetically difficult to break down.

00:46 The role of skull bone marrow in ageingDuring ageing, bone marrow in the skull becomes an increasingly important site of blood-cell production. This is in stark contrast to most bones where the ability of marrow to make blood and immune cells declines. Studies in mice and humans showed that ageing results in skull bone-marrow expanding, and in mice this marrow was more resistant to inflammation and other hallmarks of ageing. The team behind the work hope by understanding this process better it may be possible to help organs become more resistant to ageing.Research Article: Koh et al.08:56 Research HighlightsElderly big brown bats show remarkable resistance to age-related hearing loss, and why search-engine algorithms may not be the main driver steering people towards misinformation.Research Highlight: No hearing aids needed: bats' ears stay keen well into old ageResearch Highlight: Don't blame search engines for sending users to unreliable sites11:38 How to make lead a useful material to date the Solar SystemResearchers have overcome a major hurdle preventing the radioactive isotope lead-205 from being used as a ‘clock' to date the age of the Solar System. 205Pb is made in some stars and thanks to its half life of around 17 million years has been proposed as a potential way to date ancient astronomical processes. However, exactly how much 205Pb can escape a star were unclear, limiting its dating potential.

Surprise finding reveals mitochondrial 'energy factories' come in two different types

00:46 Mitochondria divide their labour to help cells thriveResearchers have uncovered that mitochondria divide into two distinct forms when cells are starved, a finding that could help explain how some cancers thrive in hostile conditions. Mitochondria are cellular powerhouses, creating energy and vital metabolic molecules, but how they are able to do this when resources are limited has been a mystery. It turns out that in nutrient-poor situations, mitochondria split into two separate types, one which concentrates on energy production, the other on producing essential cellular building blocks. Together these allow cells to make everything they need. The team showed that this also happens in certain cancer cells, which may help them survive and grow under hostile conditions in the body.Research Article: Ryu et al.News and Views: Division of labour: mitochondria split to meet energy demandsVideo: A new kind of mitochondrion07:53 Research HighlightsA tidy genome may explain naked mole rats' long lifespans, and why the midlife crisis may not be as ubiquitous as previously thought.Research Highlight: Naked mole rats vanquish genetic ghosts — and achieve long lifeResearch Highlight: The midlife crisis is not universal10:41 A smashing way to snapshot an atomic nuclei's shapePhysicists have revealed a new technique to image the shape of atomic nuclei — by smashing them together. The nucleus of an atom doesn't really resemble what is shown in textbooks — they actually come in a variety of shapes, which drive an element's behaviour. Current methods essentially take a long-exposure photo of an atom's nucleus, which doesn't capture the subtle variations in how the protons and neutrons arrange themselves. The new method overcomes this by colliding nuclei together and then using information on the resulting debris to reconstruct the shape of the nucleus. The researchers hope that this technique can help physicists resolve many more mysteries about atomic nuclei.Research Article: STAR CollaborationNews: Scientists worked out the shapes of atomic nuclei — by exploding them19:51 Briefing ChatAnalysing the genome of an ancient clone forest has revealed it could be up to 80,000 years old, and how putting limits on the famous infinite monkey theorem means they probably wouldn't churn out Shakespeare before the end of the Universe.Nature: The world's oldest tree?
