In this episode: 00:46 Mysterious methane emission from a cool brown dwarf The James Webb Space Telescope (JWST) is revealing the makeup of brown dwarfs — strange space objects that blur the line between a planet and a star. And it appears that methane in the atmosphere of one of these objects, named W1935, is emitting infrared radiation. Where the energy comes from is a mystery however, researchers hypothesise that the glow could be caused by an aurora in the object’s atmosphere, perhaps driven by an as-yet unseen moon. Research Article: Faherty et al. 10:44 Research Highlights The discovery that bitter taste receptors may date back 450 million years, and the first planet outside the Solar System to boast a rainbow-like phenomenon called a ‘glory’. Research Highlight: Bitter taste receptors are even older than scientists thought Research Highlight: An exoplanet is wrapped in glory 13:07 How working memory works Working memory is a fundamental process that allows us to temporarily store important information, such as the name of a person we’ve just met. However distractions can easily interrupt this process, leading to these memories vanishing. By looking at the brain activity of people doing working-memory tasks, a team have now confirmed that working memory requires two brain regions: one to hold a memory as long as you focus on it; and another to control its maintenance by helping you to not get distracted.

In this episode: 00:46 Mapping ‘ghost roads’ in tropical forests Across the world, huge numbers of illegal roads have been cut into forests. However, due to their illicit nature, the exact numbers of these roads and their impacts on ecosystems is poorly understood. To address this, researchers have undertaken a huge mapping exercise across the tropical Asia-Pacific region. Their findings reveal over a million kilometers of roads that don’t appear on official maps, and that their construction is a key driver for deforestation.

Around the world, rates of cancers that typically affect older adults are increasing in those under 50 years old. Models based on global data predict that the number of early-onset cancer cases like these will increase by around 30% between 2019 and 2030. The most likely contributors — such as rising rates of obesity and early-cancer screening — do not fully account for the increase. To try and understand the reasons behind this trend, many researchers are searching for answers buried in studies that tracked the lives and health of children born half a century ago. This is an audio version of our Feature Why are so many young people getting cancer? What the data say Hosted on Acast. See acast.com/privacy for more information.

In this episode: 00:35 Pregnancy advances your ‘biological’ age — but giving birth turns it back Growing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA, but new research suggests that after giving birth, these changes can revert to an earlier state. Nature News: Pregnancy advances your ‘biological’ age — but giving birth turns it back 08:07 Bird gestures to say 'after you' A Japanese tit (Parus minor) will flutter its wings to invite their mate to enter the nest first. Use of these sorts of gestures, more complex than simply pointing at an object of interest, were thought to be limited to great apes, suggesting that there are more non-vocal forms of communication to be found in the animal kingdom. Scientific American: Wild Birds Gesture ‘After You’ to Insist Their Mate Go First 13:34 The carbon cost of home-grown veg Research have estimated that the carbon footprint of home-grown food and community gardens is six-times greater than conventional, commercial farms. This finding surprised the authors — keen home-growers themselves — who emphasize that their findings can be used to help make urban efforts (which have worthwhile social benefits) more carbon-efficient.

In this episode: 01:28 Inflammation’s role in memory How memories are stored is an ongoing question in neuroscience. Now researchers have found an inflammatory pathway that responds to DNA damage in neurons has a key role in the persistence of memories. How this pathway helps memories persist is unclear, but the researchers suggest that how the DNA damage is repaired may play a role. As inflammation in the brain is often associated with disease, the team were surprised by this finding, which they hope will help uncover ways to better preserve our memories, especially in the face of neurodegenerative disorders. Research Article: Jovasevic et al. News and Views: Innate immunity in neurons makes memories persist 08:40 Research Highlights The effect of wind turbines on property values, and how waste wood can be used to 3D print new wooden objects. Research Highlight: A view of wind turbines drives down home values — but only briefly Research Highlight: Squeeze, freeze, bake: how to make 3D-printed wood that mimics the real thing 11:14 How melting ice is affecting global timekeeping Due to variations in the speed of Earth’s rotation, the length of a day is rarely exactly 24 hours. By calculating the strength of the different factors affecting this, a researcher has shown that while Earth’s rotation is overall speeding up, this effect is being tempered by the melting of the polar ice caps. As global time kept by atomic clocks occasionally has to be altered to match Earth’s rotation, human-induced climate change may delay plans to add a negative leap-second to ensure the two align.

This podcast has been corrected: in a previous version at 5:55 we stated that that the team's 200mm devices currently contain only a couple of magnetic tunnelling junctions, in fact they studied 500-1000 devices in this work. 00:48 How mysterious skyrmions could power next-generation computers Skyrmions are tiny whirlpools of magnetic spin that some researchers believe have useful properties that could unlock new kinds of computing. However getting skyrmions to perform useful computational tasks has been tricky. Now researchers have developed a method to create and manipulate skyrmions in a way that is compatible with existing computing technology, allowing them to read and write data at a fraction of the energy cost of conventional systems. The team think this shows that skyrmions could be a viable part of the next generation of computers. Research Article: Chen et al.

How female birds judge the fitness between these males has been a long-standing puzzle. Now, using an AI-based system a team has analysed the songs of male zebra finches and shown that some songs have a hidden factor that is imperceptible to humans. Although it’s not clear exactly what this factor is, songs containing it were shown to be harder to learn and more attractive to females. The researchers hope that this AI-based method will allow them to better understand what makes some birdsong more attractive than others. Research article: Alam et al.

In this episode: 00:45 Making a map of the human heart The human heart consists of multiple, specialised structures that all work together to enable the organ to beat for a lifetime. But exactly which cells are present in each part of the heart has been difficult to ascertain. Now, a team has combined molecular techniques to create an atlas of the developing human heart at an individual cell level. Their atlas provides insights into how cell communities communicate and form different structures. They hope that this knowledge will ultimately help in the treatment of congenital heart conditions, often caused by irregular development of the heart. Research article: Farah et al.

Several of these species are toothed whales, such as killer whales, beluga whales and narwhals. But why menopause evolved multiple times in toothed whales has been a long-standing research question. To answer it, a team examined the life history of whales with and without menopause and how this affected the number of offspring and ‘grandoffpsring’. Their results suggest that menopause allows older females to help younger generations in their families and improve their chances of survival. Research Article: Ellis et al.

In this episode: 00:48 Bumblebees can learn new tricks from each other One behaviour thought unique to humans is the ability to learn something from your predecessors that you couldn’t figure out on your own. However, researchers believe they have shown bumblebees are also capable of this ‘standing on the shoulders of giants’ approach to learning. Bees that were taught how to complete a puzzle too difficult to solve on their own, were able to share this knowledge with other bees, raising the possibility that this thought-to-be human trait could be widespread amongst animals.

Now research shows that the tiny elephantnose fish can increase the range of this sense by combining its pulses with those of other elephantnose fish. This allows them to discriminate and determine the location of different objects at a much greater distance than a single fish is able to. This is the first time a collective electric sense has been seen in animals, which could provide an ‘early-warning system', allowing a group to avoid predators from a greater distance.

In this episode: 00:49 What caused the Universe to become fully transparent? Around 13 billion years ago, the Universe was filled with a dense ‘fog’ of neutral hydrogen that blocked certain wavelengths of light. This fog was lifted when the hydrogen was hit by radiation in a process known as reionisation, but the source of this radiation has been debated. Now, researchers have used the JWST to peer deep into the Universe’s past and found that charged particles pouring out from dwarf galaxies appear to be the the main driver for reionization. This finding could help researchers understand how some of the structures we now see in the Universe were formed. Research article: Atek et al. 08:46 Research Highlights Ancient inscriptions could be the earliest example of the language that became Basque, and how researchers etched a groove… onto soap film.

Controlling cholesterol by editing the epigenome has shown promise in lab-grown cells, but its efficacy in animals was unclear. Now, researchers have shown the approach can work in mice, and have used it to silence a gene linked to high cholesterol for a year. The mice show markedly lowered cholesterol, a result the team hope could pave the way for epigenetic therapeutics for humans. Research Article: Cappelluti et al. 18:52 The gene mutation explaining why humans don’t have tails Why don’t humans and other apes have a tail? It was assumed that a change must have happened in our genomes around 25 million years ago that resulted in the loss of this flexible appendage. Now researchers believe they have pinned down a good candidate for what caused this: an insertion into a particular gene known as TBXT. The team showed the key role this gene plays by engineering mice genomes to contain a similar change, leading to animals that were tail-less. This finding could help paint a picture of the important genetic mutations that led to the evolution of humans and other apes.

The phenomenon of animals catching diseases from humans, called reverse zoonoses, has had a severe impact on great ape populations, often representing a bigger threat than habitat loss or poaching. However, while many scientists and conservationists agree that human diseases pose one of the greatest risks to great apes today there are a few efforts under way to use a research-based approach to mitigate this problem.

The deep haunting tones of the world's largest animals, baleen whales, are iconic - but how the songs are produced has long been a mystery. Whales evolved from land dwelling mammals which vocalize by passing air through a structure called the larynx - a structure which also helps keep food from entering the respiratory system. However toothed whales like dolphins do not use their larynx to make sound, instead they have evolved a specialized organ in their nose. Now a team of researchers have discovered the structure used by baleen whales - a modified version of the larynx. Whales like Humpbacks and Blue whales are able to create powerful vocalizations but their anatomy also limits the frequency of the sounds they can make and depth at which they can sing. This leaves them unable to escape anthropogenic noise pollution which occur in the same range.

In this episode: 00:45 Why are humans so helpful? Humans are notable for their cooperation and display far more altruistic behaviour than other animals, but exactly why this behaviour evolved has been a puzzle. But in a new paper, the two leading theories have been put the test with a model and a real-life experiment. They find that actually neither theory on its own leads to cooperation but a combination is required for humans to help one another. Research article: Efferson et al.

For over a century, cancer has been classified by areas of the body - lung cancer, breast cancer, skin cancer etc. And yet modern medical research is telling us that the molecular and genetic mechanisms behind cancers are not necessarily tied to parts of the body. Many drugs developed to treat metastatic cancers have the capacity to work across many different cancers, and that presents an opportunity for more tailored and efficient treatments. Oncologists are calling for a change in the way patients, clinicians and regulators think about naming cancers.

In this episode: 0:46 Borrowing tricks from cancer could help improve immunotherapy T cell based immunotherapies have revolutionised the treatment of certain types of cancer. However these therapies — which involved taking someone’s own T cells and reprogramming them to kill cancer cells — have struggled to treat solid tumours, which put up multiple defences. To overcome these, a team has taken mutations found in cancer cells that help them thrive and put them into therapeutic T cells. Their results show these powered-up cells are more efficient at targeting solid tumours, but don’t turn cancerous themselves.

Cervical cancer is both treatable and preventable, and the WHO has called for countries to come together to to eliminate the disease in the next century. However the disease still kills over 300,000 people each year, and levels of screening, treatment and vaccination need to be stepped up in order to achieve this goal. These challenges are particularly stark in low- and middle-income countries, where a lack of funding, staffing and infrastructure are obstacles. Vaccine hesitancy, especially in light of the COVID-19 pandemic, is also a key problem.

Evidence so far suggests that the prevalence of long COVID in low- and middle-income countries could be similar to that of wealthier countries. For example, by some estimates, more than four million people in Brazil have long COVID.
