Octopuses hunt by 'tasting' with their suckers
12/04/2023 Duration: 27min00:44 The unusual receptors that let octopuses hunt by touchResearchers have shown that the suckers of octopuses are covered with specialised receptors that allow them to taste by touching things. Similar receptors are also found in squid, but there are differences that mirror differences in the animals’ hunting behaviours; while octopuses feel for their prey, squid pull things towards themselves before deciding whether or not to eat it.Research article: Kang et al.Research article: Allard et al.Nature video: How octopuses taste with their arms08:48 Research HighlightsHow climate change has been linked to a devastating avalanche in the Italian Alps, and evidence of hallucinogenic drug use in prehistoric Europe.Research Highlight: A glacier’s catastrophic collapse is linked to global warmingResearch Highlight: Hair buried in a cave shows hallucinogen use in ancient Europe11:31 Briefing ChatWe discuss some highlights from the Nature Briefing.

Giant black-hole pair from the early Universe gives clues to how galaxies form
05/04/2023 Duration: 31min00:46 A pair of supermassive black holes in the distant universeSupermassive black holes are found at the centre of galaxies across the universe. But observations of galaxies with more than one – caused by the merging of two galaxies – have been rare. Now, researchers have combined data from a number of telescopes and satellites, to reveal a pair of supermassive blackholes farther from Earth than any pair detected previously. They hope this will offer insights into how galaxies form.Research article: Chen et al.News and Views: Distant supermassive black holes spotted in galaxy merger10:53 Research HighlightsWhy appetite can increase after dieting, and gliding mammals’ flight-associated genes.Research Highlight: Can’t keep off lost weight?

Audio long read: What Turkey’s earthquake tells us about the science of seismic forecasting
31/03/2023 Duration: 11minLast month, a magnitude-7.8 earthquake struck Turkey and Syria, killing an estimated 50,000 people. Two decades ago, researchers suggested that an earthquake in this area was likely, but exactly where and when it would strike were unknown.This shows both the promise — and limitations — of the science of earthquake forecasting. Years of research suggest that it may be impossible to predict exactly when an earthquake will occur. As a result, many in the field have now shifted to identifying high risk fault segments to help policymakers take steps to avoid death and destruction.This is an audio version of our Feature: What Turkey’s earthquake tells us about the science of seismic forecasting Hosted on Acast.

How to make driverless cars safer — expose them to lots of dangerous drivers
22/03/2023 Duration: 19min00:46 A new test to get autonomous vehicles on the roadTruly autonomous vehicles, ones that don't require a driver to be present and are driven by AI, aren't yet safe for public use. Part of the reason for this is it has been difficult to train them to deal with rare dangerous situations. Now researchers are unveiling a new approach to present lots of these infrequent events to the AI very rapidly, speeding up the training and testing process.Research Article: Feng et al.News and Views: Hazards help autonomous cars to drive safelyVideo: The driving test for driverless cars08:23 Research HighlightsHow bird-flu is adapting to mammals, and the effect of negative headlines.Research Highlight: Bird-flu virus makes itself at home in Canada’s foxes and skunksResearch Highlight: It’s bad!

How to build a virus-proof cell
15/03/2023 Duration: 31min00:47 An edited genetic code that prevents viral infectionResearchers have engineered bacteria with synthetic genomes to be immune to viral infection. The team streamlined the bacteria’s genetic code, and re-engineered the protein-producing machinery to insert the wrong amino acid if used by a virus, effectively making the bacteria ‘speak’ a different language to any invaders. It’s hoped that this technique could be used to reduce unwanted sharing of genes from modified organisms.Research article: Nyerges et al.News & Views: Synthetic bacterial genome upgraded for viral defence and biocontainment07:42 Research HighlightsEstimating the methane output of an enormous wetland ecosystem, and how honeybees improve their dance moves with a little help from their elders.Research Highlight: Methane from one of Earth’s largest wetland complexes is set to soarResearch Highlight: Watch them waggle: bees dance better after lessons from elders10:02 How mini-MRI scanners could improve access to imagingMagnetic resonance

How the Australian wildfires devastated the ozone layer
08/03/2023 Duration: 26min00:47 Wildfire smoke’s chemical composition enhances ozone depletionSmoke from the devastating Australian wildfires of 2019-2020 led to a reduction in ozone levels in the upper atmosphere, but it’s been unclear how. Now, a team proposes that smoke’s particulate matter can enhance the production of ozone depleting chemicals, matching satellite observations during the Australian fires. The results spark concerns that future wildfires, which are set to grow more frequent with ongoing climate change, will undo much of the progress towards restoration of the ozone layer.Research article: Solomon et al.News & Views: How wildfires deplete ozone in the stratosphere08:27 Research HighlightsA global analysis of bats reveals the species most likely to be hunted by humans, and the stem cells that allow deer antlers to regrow.Research Highlight: Big bats fly towards extinction with hunters in pursuitResearch Highlight: Mice grow ‘mini-antlers’ thanks to deers’ speedy stem cells10:53 Modelling food systems with ‘digita

How an increased heart rate could induce anxiety in mice
01/03/2023 Duration: 18min00:47 How a racing heart could trigger anxietyAnxiety can make the heart beat faster, but could the reverse be true as well? That question has been much debated, but hard to test. Now, a team has shown that artificially increasing a mouse’s heart rate can induce anxiety-like behaviours, and identified an area in the brain that appears to be a key mediator of this response. They hope that this knowledge could help to improve therapies for treating anxiety-related conditions in the future.Research article: Hsueh et al.News & Views: How an anxious heart talks to the brain08:32 Research HighlightsThe chance discovery of the smallest rock seen so far in the Solar System, and the first brain recording from a freely swimming octopus.Research Highlight: Asteroid photobombs JWST practice shotsResearch Highlight: How to measure the brain of an octopus10:57 How NASA’s DART mission beat expectiationsIn September 2022, NASA’s DART spacecraft smashed into a space rock known as Dimorphos, which orbits a near-Earth aster

Nature's Take: How Twitter's changes could affect science
27/02/2023 Duration: 26minTwitter has become indispensable to many scientists. It is a place to share findings, raise their profile, and is even used as a source of data in many studies.In recent months though, the site has been in turmoil after a swathe of policy changes in light of Elon Musk's takeover. Never a stranger to misinformation and abuse, these problems have reportedly gotten worse. Additionally, the ability to use Twitter as a source of data is in peril, and malfunctions are more commonplace.In this episode of Nature's Take we discuss how these changes are affecting the platform and the knock-on effects on science.

Audio long read: How your first brush with COVID warps your immunity
24/02/2023 Duration: 16minImprinting is a quirk of the immune system in which someone’s initial exposure to a virus biases their immune response when they meet the same virus again.Studies are showing how imprinting shapes people’s responses to SARS-CoV-2; those infected with earlier strains can mount weaker responses to a later Omicron infection.This phenomenon is dampening the hope that variant-tailored boosters will markedly reduce transmission of the virus, although researchers agree that variant-tailored boosters are worth getting because they still provide some immunity, and prevent serious illness.This is an audio version of our Feature: How your first brush with COVID warps your immunity Hosted on Acast.

How 'metadevices' could make electronics faster
15/02/2023 Duration: 30min00:47 A metadevice for faster electronicsIn the past, increasing the speeds of electronics required designing smaller components, but further reductions in size are being hampered by increasing resistance. To get around this, researchers have demonstrated a ‘metadevice’, which prevents resistance building up by concentrating the flow of signals into specific regions of the device. The hope is that this meta-method could be used to create even smaller electrical components in the future.Research article: Nikoo & Matioli06:27 Research HighlightsHow waiting times for services are higher for people in the US with low incomes, and how your brain hears an alarm while you’re asleep.Research Highlight: Who wastes more time waiting?

This mysterious space rock shouldn’t have a ring — but it does
08/02/2023 Duration: 28min0:46 The mysterious ring in the distant Solar SystemQuaoar is a small, rocky object that lies beyond Neptune’s orbit. In an unexpected discovery, researchers have shown that this object has its own orbiting ring, similar to those seen encircling planets like Saturn. However, Quaoar’s ring shouldn’t exist, as it is at a distance far outside the theoretical limit at which rings are thought to be stable, and researchers are trying to figure out why.Research article: Morgado et al.News and Views: A planetary ring in a surprising place07:01 Research HighlightsA repurposed skin-disease drug suppresses alcohol consumption in people with alcohol-use disorder, and how volcanic eruptions may have contributed to social unrest in ancient Egypt.Research Highlight: Pill for a skin disease also curbs excessive drinkingResearch Highlight: Volcanic quartet linked to bad times in ancient Egypt09:26 Air pollutionExposure to polluted air has been linked to millions of deaths each year.
