First living transparent mouse; lab-grown stem cells; Spy balloons

Season 1 · Episode 266

Friday, September 6, 2024 • Duration 22:47

🎧 Episode 266

⚡️ The first human blood stem cells have been created in a lab and successfully turned into functioning bone marrow. This research could revolutionise the treatment of blood cancers like leukaemia and lymphoma. So far it’s only been tested on mice, but researchers are hopeful it could work in humans too.

⚡️ In other mouse news, we are now able to turn mice see-through. Using a surprisingly common food dye, researchers have turned the skin of living mice transparent. The technique, which didn’t harm the mice, offers a new (though gruesome) look into the living body.

⚡️ The US is planning to launch spy balloons to carry out surveillance and act as backup communication links. The news comes just a year after the US shot down a Chinese balloon that was full of intelligence-gathering equipment. Coincidence? Find out why balloons are making a comeback.

⚡ Bats have a huge role in human health, often harbouring diseases that are then passed onto us, such as rabies and covid-19. But it turns out when bat populations collapse, that’s also bad for human health. New research finds that when bats die, insecticide use in agriculture goes up and so does infant mortality – find out how the three are linked.

⚡ How dark is deep space? Are there any regions of the universe that are completely and utterly devoid of all light? Researchers now have an answer. Plus, ISS astronauts report a strange noise on Boeing’s stranded Starliner capsule.

🎙️ Hosts Timothy Revell and Christie Taylor discuss with guests James Woodford, Chris Simms, Jeremy Hsu and Michael Le Page.

Could mpox be the next covid-19?; Science of beat drops; Clothes made from potatoes

Season 1 · Episode 265

Friday, August 30, 2024 • Duration 27:15

🎧 Episode 265

⚡️ The latest mpox variant has infected a record number of people in central Africa, has been found in travellers in Sweden and Thailand, and the World Health Organization has now declared it a public health emergency of international concern – just 15 months after the previous such declaration for mpox expired in 2023. But is this virus likely to become another covid? And as health authorities in the most affected countries struggle to keep it under control, will we be able to avoid further global outbreaks of the disease?

⚡️ New rogue worlds have been discovered in our galaxy that resemble both planets and stars but are neither. Thought to be brown dwarfs, the sheer number of them calls into question our understanding of how planet-sized objects form. This, plus another failed – but also successful – attempt to find dark matter’s hypothesised WIMPs.

⚡️ As a piece of music builds up to its crescendo, our brains know exactly when the beat is about to drop. Researchers have discovered the parts of our brains that are responsible for making sense of musical changes or “boundaries” – and this is true whether you’re listening to Mozart or Metallica.

⚡ Clothes made from…potatoes? An idea to turn fibres from potato stems into fabric has turned from concept to reality. If we can use potato fibres instead of other more energy intensive materials, the designers say, we could reduce the environmental footprint of clothing production.

🎙️ Hosts Timothy Revell and Christie Taylor discuss with guests Alexandra Thompson, Leah Crane, Grace Wade and Madeleine Cuff.

Even more powerful gene editing than CRISPR; first moon samples from the far side; dangerous new mpox

Season 1 · Episode 256

Friday, June 28, 2024 • Duration 23:17

#256

A new gene editing technique may be more powerful than CRISPR. Bridge editing is still in its infancy, but could be revolutionary for its ability to more specifically target gene substitutions. This method of altering DNA may let us create single treatments for gene mutations across large groups of people – something even CRISPR can’t do.

China’s Chang’e 6 spacecraft has returned to Earth with samples from the far side of the moon – the first ever. Hear what the samples may tell us about this hard-to-study part of the lunar surface, plus what China is planning for its next big exploration missions.

A dangerous new strain of mpox, formerly known as monkeypox, has been identified in the Democratic Republic of the Congo. A thousand cases have been reported since September and several hundred people have died. What makes this strain so dangerous and can it be kept under control?

A fossil has been discovered that is thought to be a Neanderthal child who had Down’s syndrome. It’s estimated the child lived to at least 6 years old and may have received extra care from the community – more evidence that Neanderthals weren’t as brutish and unfeeling as thought.

Why some people never get covid-19; Chimps using herbal medicines; Largest ever Maxwell’s demon

Season 1 · Episode 255

Friday, June 21, 2024 • Duration 24:11

#255

Why do some people seem to be naturally immune to covid-19? We may finally have the answer and it’s to do with differences in the way immune cells function. Will the finding help us predict who’s immune and who isn’t – and more?

Artificial intelligence is being used to tackle the problem of clearing mines from enormous swaths of Ukraine. Russia has scattered vast amounts of ordinance across Ukraine, tearing up agricultural land and leaving behind chemical contamination. The clean-up operation could take 700 years to complete in total. AI is helping Ukraine to work out where to start.

Chimpanzees are herbal medicine enthusiasts: when sick, they seem to seek out specific plants. But how effective are the plants they’re swallowing at actually dealing with illness? Wild chimps in Uganda’s Budongo Forest are helping researchers to understand the practice.

Maxwell’s demon, a thought experiment that involves a tiny imp, was once thought to disprove the second law of thermodynamics. Now researchers have built a real-life Maxwell’s demon that is not only the largest of its kind so far but could be used to discover new drugs and clean CO2 from the air.

Elephants have names for each other; conspiracies and doppelgangers with Naomi Klein; an ancient galactic weather report

Season 1 · Episode 254

Friday, June 14, 2024 • Duration 36:52

We know elephants are smart, but it seems we’ve only scratched the surface in understanding their intelligence. It turns out African elephants seem to have unique names for each other – maybe even nicknames. If it’s true, humans would no longer be alone in this practice. A team has been analysing their rumbly greeting calls using AI. Is this a hint that we’ve been wrong about other animals, too?

It’s a weather report like no other: two to three million years ago, the protective bubble called the heliosphere that surrounds the sun and the planets crashed into a galactic cloud. This left Earth exposed to the radioactive particles of interstellar space for as long as ten thousand years. And it could even have impacted evolution.

Naomi Klein won the Women’s Prize for nonfiction this week for her book Doppelganger: A Trip Into the Mirror World. Rowan Hooper speaks to Naomi following the win, as the pair dig into the strange confluence of the alt-right and wellness influencers, why conspiracy theories have become so widespread and how grifters and charlatans are exploiting the uncertain times we live in.

Astronauts have been sending biological samples like blood and faeces to a new space “biobank”. It’s all in an effort to better understand the impact of space travel on human health. As a bonus, read Clare’s story on the ‘vomit comet’ here.

Why we should drill a massive hole in the moon; banning fossil fuel advertising; how to stop being lonely

Season 1 · Episode 253

Friday, June 7, 2024 • Duration 28:29

#253

The moon may hold the answer to a decades-long physics conundrum – all we need to do is drill several kilometres into its surface. For years, physicists have been searching for protons that fall apart or decay into other particles, but they’ve always come up empty handed. So why do they think they might find them on the moon?

A new update on the state of the world’s climate has not brought cheery news. A report looking at 2023 has revealed the world is warming at a record rate – with estimates suggesting we may blow past our 1.5oC temperature goals in just five years. As the UN Secretary General calls for urgent action, we hear about calls to ban fossil fuel advertising, just as ads for smoking were banned in the past.

If you ever feel lonely… you’re not alone. Social connections are hugely beneficial for our health. But many of us aren’t reaping their full therapeutic benefits, often due to our own misconceptions about social situations. But researchers are on the case, with simple tools and tricks to help us connect better to other people. David Robson shares some actionable tips, as he discusses his new book The Laws of Connection: The Scientific Secrets of Building a Strong Social Network.

Five children born deaf have gained the ability to hear in both ears after receiving a new gene therapy. The groundbreaking treatment targets a gene called otoferlin, which is defective in some people with deafness – and the results are very encouraging.

Google’s AI search problem; time is a quantum illusion; can we stop ageing?

Season 1 · Episode 252

Friday, May 31, 2024 • Duration 33:09

#252

It is not wise to stick cheese on your pizza with glue, even if Google tells you to do it. This is just one recommendation in a string of blunders made by Google’s new AI search engine. It uses a large language model to summarise your searches, but clearly it’s not always working as planned. Can (and will) the company fix it?

No matter what language you speak, when you hear the word “bouba”, you probably imagine a round shape. And “kiki’ will likely make you think of a sharp shape. This example of sound symbolism is thought to be a precursor to human language. But it may not be unique to humans – even chickens may make this association too, hinting at a deeper evolutionary role.

Some physicists have long theorised that time is just an illusion that emerges from quantum properties of the universe. And there’s even a new study that backs this idea up. If the maths is right, it could finally help us unite the worlds of big and small physics.

We now know enough about the ageing process that scientists believe we can start to slow it down or even stop it altogether. Nobel Prize winning biologist Venki Ramakrishnan has written a new book, Why We Die, which explores the new science of ageing and longevity. Find out what he’s learnt and what he thinks are the most promising areas of research.

The clean energy revolution relies on rare earth metals for things like batteries and solar panels. But mining for them has its own environmental drawbacks. But seaweed may be able to help us with that. It turns out some species collect the minerals we need without damaging the environment. Will seaweed mining be the next big thing?

Record hurricane season approaches; uncovering the mysteries of a rare earth metal; how to fight in Bronze Age armour

Season 1 · Episode 251

Friday, May 24, 2024 • Duration 27:07

#251

Hurricane season in the Atlantic ocean is set to be extremely active, according to forecasts. Expect to see as many as 25 named tropical storms, with many likely to become hurricanes. Find out how high sea surface temperatures and shifting El Niño conditions are creating the perfect conditions for a potentially record breaking season.

The sun’s magnetic field may function quite differently to Earth’s. We’ve long assumed it originates from deep within but it seems the sun has a different way of doing things.

Promethium is a lesser known and rare element on the periodic table that is incredibly hard to find naturally. And even though scientists know how to produce it, it’s still incredibly hard to study, as the radioactive material decays quickly. But that’s all changing as researchers have figured out a way to keep it stable for longer. What will they learn about this mysterious element?

Dwarf plants found on the Japanese island of Yakushima may have evolved to be small thanks to deer. Sika deer are the island’s resident herbivore and their voracious appetites seem to have driven the evolution of many local plant species – giving us new insights into how unrelated organisms evolve together.

Plus: How Argentine ants get better at learning the more caffeine you feed them; why the Greek army has been suiting up in extremely heavy Bronze Age armour; and the most powerful pulse of X-rays ever seen on Earth.

Hosts Christie Taylor and Sophie Bushwick discuss with guests James Dinneen, Leah Crane, Alex Wilkins and Molly Glick. To read more about these stories, visit newscientist.com.

Hints of alien life in our galaxy; freezing human brains; solving a mystery of Egypt’s pyramids

Season 1 · Episode 250

Friday, May 17, 2024 • Duration 28:20

#250

There are signs that aliens might be harnessing the power of stars in our galaxy to fuel their civilisations. Dyson spheres are structures that surround entire stars to absorb their energy. Although these are just hypothetical, researchers have detected hints of their existence. But aliens aren’t the only possible explanation.

Being able to freeze human brain tissue could be a game-changer for medical research. While freezing brains is easy, thawing them out without damaging the tissue is much harder. But now a method involving a cocktail of chemical ingredients seems to have solved the problem..

The largest ever ‘ecoacoustic’ survey is being conducted throughout the forests of Costa Rica. Sound recordings of various habitats, from degraded pastures to regenerating forests, are being gathered to assess the biodiversity and health of the country’s ecosystems. Hear some of the amazing soundscapes that have been captured for the survey.

Orchids may share food with their offspring. Lab experiments have shown for the first time that parent orchids may be using fungal pathways – the mycorrhizal network – to send vital sugars to seedlings that cluster around them.

Ancient Egyptians were reliant on the Nile river to transport materials used to build the world famous pyramids. But many of those pyramids are built on inhospitable, arid land, far from the Nile. So how did they get the materials there? Geoscientists may have uncovered an ancient clue.

Do sperm whales have an alphabet?; Why dark energy is so weird; US bird flu outbreak

Season 1 · Episode 249

Friday, May 10, 2024 • Duration 25:17

#249

Do whales have their own alphabet? We’ve long thought the clicking sounds that sperm whales make is their way of chatting to each other, but those clicks may be even more sophisticated than we realised. After analysing whale recordings, researchers suggest the different click patterns are complex enough to form an alphabet – the closest thing to human communication we’ve yet seen in animals.

We know very little about dark energy – and it turns out we may know even less than we thought. This mysterious force, which accelerates the expansion of the universe, may be changing in an unexpected way, calling our entire understanding of cosmology into question. This discovery by the Dark Energy Spectroscopic Instrument in Arizona could make room for some exciting new physics.

There’s a bird flu outbreak in the US, spreading through herds of dairy cows in nine states. One dairy worker in Texas has even tested positive, though has also recovered. Underreporting and insufficient testing mean we know very little about how fast the virus is spreading. And as officials warn against drinking raw milk, how worried should we be?

Quantum batteries, while mostly still theoretical, could make charging your phone or electric car unimaginably fast. Researchers are looking at the quickest way to charge these batteries, harnessing the advantages of quantumness – like charging in two different places at once.
