02:54 The death star moon and a win for the little guysThe shifting orbit of one of Saturn’s moons indicates that the satellite has a subsurface ocean, contradicting theories that its interior is entirely solid. The finding calls for a fresh take on what constitutes an ocean moon.Nature Podcast: 14 February 2024News and Views: Mimas’s surprise ocean prompts an update of the rule book for moons07:05 Could red mud make green steel?Millions of tonnes of ‘red mud’, a hazardous waste of aluminium production, are generated annually. A potentially sustainable process for treating this mud shows that it could become a source of iron for making steel.Nature Podcast: 24 Jan 2024News and Views: Iron extracted from hazardous waste of aluminium production12:09 A hierarchy of failureA design principle for buildings incorporates components that can control the propagation of failure by isolating parts of the structure as they fail — offering a way to prevent a partial collapse snowballing into complete destruction.Nature podcast: 15 May 2024Nature video: Controlled failure: The building designed to limit catastropheNews and Views: Strategic links save buildings from total collapse17:57 Programable enzyme for genpme editingRNA-guided recombinase enzymes have been discovered that herald a new chapter for genome editing — enabling the insertion, inversion or deletion of long DNA sequences at user-specified genome positions.News and Views: Programmable RNA-guided enzymes for next-generation genome editing Hosted on Acast.

01:11 “Ozempic you’re able”In the first of our annual festive songs celebrating the science of the past year, we pay homage to Ozempic, or Semaglutide, that's able to tackle obesity, diabetes and potentially a whole lot more.05:20 A very scientific quizWe gather an all-star cast and see how well they can remember some of the big science stories from 2024 in our annual festive quiz.21:31 “CAR T Cells”In the second of our festive songs, we look at CAR-T cells. These engineered immune cells have shown great promise at tackling cancer, but these treatments are not without their drawbacks.25:43 Nature’s 10Every year, Nature’s 10 highlights some of the people who have helped shape science over the past 12 months. We hear about a few of the people who made the 2024 list, including an economist who now needs to run a country, a Russian science-sleuth, a researcher who’s been sounding the alarm on Mpox, and a PhD student who won a salary bump for researchers in Canada.News Feature: Nature’s 10Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

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 — unintended or otherwise. In our new series What’s in a name we’ll explore naming in science and how names impact the world — whether that’s how the names of storms impact public safety, how the names of diseases impact patient care, or even how the names of scientific concepts can drive the direction of research itself.In this first episode we’re looking at species names. The modern system of species naming began in the 1700s and has played a vital role in standardizing academic communication, ensuring that scientists are on the same page when they talk about an organism. 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? Its volcanoes hint at an answer13:29 Programmable cellular switchesA team of scientists have created cellular switches on the surface of cells, allowing them to control their behaviour. 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. Quantum computing could potentially open up applications beyond the capabilities of classical computers, but these systems are error-prone, making it difficult to scale them up without introducing errors into calculations. 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. This breakthrough could mean that quantum computers are getting very close to realising the useful applications that their proponents have long promised.Nature: ‘A truly remarkable breakthrough’: Google’s new quantum chip achieves accuracy milestoneSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
