00:46 Uncovering the origins of the Black DeathThe Black Death is estimated to have caused the deaths of up to 60% of the population of Europe. However, despite extensive research, the origin of this wave of disease has remained unclear. Now, by using a combination of techniques, a team have identified a potential starting point in modern day Kyrgyzstan.Research article: Spyrou et al.06:57 Research HighlightsThe cocktails of toxins produced by wriggling ribbon worms, and a tiny thermometer the size of a grain of sand.Research Highlight: A poisonous shield, a potent venom: these worms mean businessResearch Highlight: Mighty mini-thermometer detects tiny temperature changes09:22 Researchers race to understand monkeypoxAround the world, there have been a number of outbreaks of monkeypox, a viral disease that has rarely been seen in countries outside of sub-Saharan Africa. Although infection numbers are small, researchers are racing to find out what’s driving these outbreaks and the best way to contain them. We g

One of the most curious symptoms of COVID-19 is the loss of smell and taste. For most, this phenomenon is short lived, but for many around the world the symptom can persist for months or even years after the infection has cleared. Once a tell-tale sign of infection, this sensory disruption is now becoming characterised as a chronic problem and scientists are only recently getting clear answers about the mechanisms behind it. In this episode of Coronapod, we dig into the most recent studies on the causes of smell loss after infection with SARS-CoV-2, as well as the treatments scientists are proposing to tackle it.News: COVID and smell loss: answers begin to emergedSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

00:33 A headbashing relative gives insights into giraffe evolutionHow the giraffe got its long neck is a longstanding question in science. One possibility is that giraffes evolved longer necks for sexual competition, with males engaging in violent neck-swinging fights. Now, a team have described fossils of an ancient giraffoid species with a thick headpiece adapted for fighting, which could add weight to this hypothesis.Nature News: How the giraffe got its neck: ‘unicorn’ fossil could shed light on puzzle05:18 A wave of resignations signals discontent in academiaAround the world, the ‘great resignation’ has seen huge numbers of workers re-evaluating their careers and lifestyles and choosing to leave their jobs following the pandemic. Academia is no exception, with many scientists deciding to leave the sector in the face of increased workloads, systemic biases and pressure to publish.Nature Careers: Has the ‘great resignation’ hit academia?10:34 An emergency fix gets MAVEN back on trackEarlier this year, NASA’

Brain–computer interfaces (BCIs) implanted in the brains of people who are paralysed are allowing them to control prosthetics that are restoring a range of skills.Although the field is relatively young, researchers are making rapid advances in the abilities that these implants can restore. In the past few years, commercial interest in BCIs has soared, but many hurdles remain before these implants can be brought to market.This is an audio version of our Feature: The brain-reading devices helping paralysed people to move, talk and touch See acast.com/privacy for privacy and opt-out information.

00:47 The robot shoulder that exercises cellsRecreating the movements that tendon cells experience as they develop in the human body is necessary for growing tissue for transplantation, but this has been difficult to achieve in a laboratory setting. Now, a team has developed a system that uses a robot shoulder to stretch and twist these cells, which they hope could be used to improve the quality of tissue grafts in the future.Research article: Mouthuy et al.Video: A robotic Petri dish: How to grow human cells in a robot shoulder07:56 Research HighlightsA robotic surgeon that works within an MRI chamber, and an ancient human genome from a resident of Pompeii.Research Highlight: Robot surgeons steer smoothly with help from magnet-free motorResearch Highlight: Vesuvius victim yields first human genome from Pompeii10:30 Overcoming COVID-19 vaccine hesitancyIdentifying sources of vaccine hesitancy is a key challenge in public health.

Despite the devastating loss of life caused by COVID-19, some researchers are arguing that the longest lasting impact of the pandemic will be on education. UN agencies calculate that more or less all school students on the planet - 1.6 billion - have faced an average of 4.5 months of school closures owing to the pandemic, the largest disruption to education in history. Teachers have been under immense pressure to keep their students happy and learning, but it is an uphill battle. In this episode of Coronapod, we discuss the research which might guide policymakers and teachers in their attempts to repair some of this damage, and ask how implementing an evidence-based system of education could have benefits beyond the pandemic.News Feature: COVID derailed learning for 1.6 billion students.

00:45 The puzzle of PalaeospondylusOver a hundred years ago, palaeontologists discovered fossils of the aquatic animal Palaeospondylus. But since then researchers have been unable to place where this animal sits on the tree of life. Now, new analysis of Palaeospondylus’s anatomy might help to solve this mystery.Research article: Hirasawa et al.News and Views: Clues to the identity of the fossil fish Palaeospondylus08:18 Research HighlightsA strong, silk-based version of mother of pearl, and the parrots that use their heads when climbing.Research Highlight: Silk imitates mother of pearl for a tough, eco-friendly materialResearch Highlight: A ‘forbidden’ body type?

00:47 The mystery of the missing dark matterDark matter makes up most of the matter in the Universe, and is thought to be needed for galaxies to form. But four years ago, astronomers made a perplexing, and controversial discovery: two galaxies seemingly devoid of dark matter. This week the team suggests that a cosmic collision may explain how these, and a string of other dark-matter-free galaxies, could have formed.Research article: van Dokkum et al.News and Views: Giant collision created galaxies devoid of dark matter08:39 Research HighlightsHow fossil fuel burning has caused levels of helium to rise, and a high-efficiency, hybrid solar-energy system.Research Highlight: Helium levels in the atmosphere are ballooningResearch Highlight: Flower power: ‘Sunflower’ system churns out useful energy10:49 Researchers experiences of the war in UkraineWe hear the stories of scientists whose lives have been affected by Russia’s invasion of Ukraine, including researchers who have become refugees, soldiers and activists i

Millions of people around the world have been left managing the complex and amorphous syndrome that is long COVID. But the underlying cause of this myriad of symptoms is not clear. One hypothesis is that the virus is able to find a safe haven in the body from which it can bide its time and potentially re-emerge - a viral reservoir. Now researchers studying long COVID have found evidence of SARS-CoV-2 in a series of organs around the body, most notably the gut, months after the infection appears to have been cleared from the respiratory system. While there is still a long way to go before the reservoir hypothesis can be confirmed, these data provide compelling new support for the theory. In this episode of Coronapod, we discuss how the studies were carried out, why the question of long COVID's cause is so difficult to crack, and what more needs to be done to get a firm answer.News: Coronavirus ‘ghosts’ found lingering in the gutSubscribe to Nature Briefing, an unmissable daily round-up of science ne

00:57 Reviving retinas to understand eyesResearch efforts to learn more about diseases of the human eye have been hampered as these organs degrade rapidly after death, and animal eyes are quite different to those from humans. To address this, a team have developed a new method to revive retinas taken from donors shortly after their death. They hope this will provide tissue for new studies looking into the workings of the human eye and nervous system.Research article: Abbas et al.08:05 Research HighlightsA technique that simplifies chocolate making yields fragrant flavours, and 3D imaging reveals some of the largest-known Native American cave art.Research Highlight: How to make a fruitier, more floral chocolateResearch Highlight: Cramped chamber hides some of North America’s biggest cave art10:54 Did life emerge in an ‘RNA world’?How did the earliest biochemical process evolve from Earth’s primordial soup?

The true disability cost of the COVID-19 pandemic is still unknown, but more and more studies are adding to the list of potential fallout from even mild COVID 19 infection. In this episode of Coronapod we discuss a massive association study which links COVID-19 cases with an increase in the risk of developing type 2 diabetes. We delve into the numbers to ask how big the risk might be? Whether any casual relationship can be drawn from this association?

00:56 How video calls can reduce creativityAs a result of the pandemic, workers around the world have become accustomed to meeting colleagues online. To find out if this switch from face-to-face meetings came at a cost to creativity, a team compared the number of ideas generated by workers collaborating either online, or in-person. They showed that people meeting virtually produced fewer creative ideas than those working face-to-face, and suggest that when it comes to idea generation maybe it’s time to turn the camera off.Research article: Brucks & LevavNews and Views: Virtual collaboration hinders idea generationVideo: Why video calls are bad for brainstorming08:08 Research HighlightsFragments from an ancient pyramid suggest earliest known use of a Maya calendar, and how sweet snacks could damage rare iguanas’ metabolism.Research Highlight: Deer symbol hints at early adoption of Maya calendarResearch Highlight: Tourists’ sweet treats threaten rare iguanas’ health10:34 Fish skin reveals a new type of cell

Results from a huge epidemiological study found that infection by the Epstein-Barr virus increases the risk of developing multiple sclerosis 32-fold. This result, combined with emerging mechanistic insights into how the virus triggers brain damage, are raising the prospect of treating or preventing MS.These advances come at a time when researchers are more interested than ever in what happens in the months and years following a viral infection, and highlights the issues untangling the relationships between infectious diseases and chronic conditions.This is an audio version of our Feature: The quest to prevent MS — and understand other post-viral diseases.

00:46 What COP26 promises will do for climateAt COP26 countries made a host of promises and commitments to tackle global warming. Now, a new analysis suggests these pledges could limit warming to below 2˚C — if countries stick to them.BBC News: Climate change: COP26 promises will hold warming under 2C03:48 Efficiency boost for energy storage solutionStoring excess energy is a key obstacle preventing wider adoption of renewable power. One potential solution has been to store this energy as heat before converting it back into electricity, but to date this process has been inefficient. Last week, a team reported the development of a new type of ‘photothermovoltaic’ that increases the efficiency of converting stored heat back into electricity, potentially making the process economically viable.Science: ‘Thermal batteries’ could efficiently store wind and solar power in a renewable grid07:56 Leeches’ lunches help ecologists count wildlifeBlood ingested by leeches may be a way to track wildlife, suggests new resear

Since the beginning of the pandemic there has been a debate amongst researchers about whether the body's immune cells can themselves be infected by SARS-CoV-2. Now two new studies show that they can - and what's more, the work has revealed a new mechanism for the massive inflammatory response seen in severe COVID. In this episode of Coronapod, we dig into the papers, asking why it has taken so long to get an answer to this question? How immune cell infection could lead to severe disease? And whether this new mechanism could provide a new avenue for the development of therapeutics?News: What triggers severe COVID?

00:54 How Mammals’ mutation rates affects their lifespanFor biologists, a long-standing question has been why some animals live longer than others. This week a team have attempted to answer this, by measuring the rates that different animal species accumulate mutations. They show that longer-lived animals acquire mutations at a slower rate, which helps to explain why cancer risk does not scale with lifespan.Research article: Cagan et al.News and Views: Mutational clocks tick differently across species07:56 Research HighlightsA clinical trial suggests a change to the treatment of a pregnancy ailment, and astronomers identify the largest known structure produced by a single galaxy.Research Highlight: Ambitious trial inspires a rethink on a common ailment of pregnancyResearch Highlight: Even among ‘giant’ galaxies this one is record-setting10:43 The war in Ukraine’s effects on global energyMany European countries are dependent on Russian fossil fuels for energy production.

00:46 The very cool experiment looking for a proposed particlePhysics tells us that when matter is created, antimatter should be as well. But while the Universe is full of matter, there’s surprisingly little antimatter to be found. To try and understand this imbalance, a team have built a detector kept just above absolute zero which they are using to look for a hypothesised, ultra-rare type of particle decay that could create matter without antimatter.Research article: The CUORE CollaborationNews and Views: Cryogenic mastery aids bid to spot matter creation09:43 Research HighlightsSubsidence of coastal cities makes them more vulnerable to sea-level rise, and tackling ‘crazy ants’ with a parasitic fungus.Research Highlight: Global cities are sinking — and humans are partly to blameResearch Highlight: Marauding crazy ants come to grief when a fungus comes to call12:17 Solving the puzzle of the missing plasmidsBacteria are well known for their ability to share genes, which they often do using small circles of DN
