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

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.

CultureLab: On the hunt for alien life with Lisa Kaltenegger

If (or maybe when) we find alien life in the universe, will it look like us? As telescopes become bigger, our ability to peer into the cosmos is only getting better. So the question may not be “will we find something?” but rather “what exactly should we be looking for?”

Lisa Kalteneggar is an astrophysicist and founding director of Cornell University's Carl Sagan Institute. She even works out of Sagan’s old office and shares the same optimism and enthusiasm he brought to the search for extraterrestrial life. 

Abby Beall speaks to her about her new book Alien Earths: Planet Hunting in the Cosmos, which takes readers on a cosmic adventure to faraway exoplanets with oceans of lava and multiple suns. 

Through the conversation Lisa explains how Earth’s geological history can help inform our search for life, while acknowledging alien life may not look the same as us. She discusses the technology that has allowed us to enter a new epoch of exploration – and what technological advancements are needed to help advance our search for alien life. And she examines the alien worlds that feature in various science fiction worlds, like those in Star Wars and Avatar, and whether they could actually exist somewhere in the universe.

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

#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?

Hosts Timothy Revell and Christie Taylor discuss with guests Matthew Sparkes, Chen Ly, Karmela Padavic-Callaghan and James Dinneen.

Dead Planets Society: Removing Mars’s Iron With a Magnet

When you bring a giant magnet to Mars, apocalyptic eruptions are just the beginning. In an attempt to suck out all of the iron from the red planet, Leah Crane and Chelsea Whyte end up shattering it like an Easter egg.

Their new cosmic plaything, a U-shaped Wile E. Coyote-esque magnet, is used in various different ways for the purposes of complete annihilation. 

With the help of science journalist and volcanologist Robin George Andrews, the team squeeze the core out like it’s toothpaste, turn the magnet into a projectile, bring multiple magnets to the fray to create a work of cosmic art and even hollow out the planet to fill it up with… SPIDERS!

Dead Planets Society is a podcast that takes outlandish ideas about how to tinker with the cosmos – from punching a hole in a planet to unifying the asteroid belt to destroying the sun – and subjects them to the laws of physics to see how they fare.

Your hosts are Leah Crane and Chelsea Whyte.

If you have a cosmic object you’d like to figure out how to destroy, email the team at [email protected]. It may just feature in a later episode.

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

#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.

CultureLab: Emily H. Wilson celebrates the expansive world of science fiction

From Dune to The Three Body Problem, is science fiction having a moment? Attention to the genre, as well as TV and films based on it, seems to have exploded in the past few years. With sci-fi often getting a bad rap, it’s time to ditch the snobbery and celebrate its complexity and diversity. And who better to do this with than New Scientist’s science fiction columnist – and our former editor – Emily H. Wilson?

Wilson is a journalist and author. In 2023 she published Inanna, the first of The Sumerians, a trilogy set in the ancient civilisation of Sumer. The books are an epic, speculative retelling of some of the oldest myths ever recorded.

In this episode, Rowan Hooper speaks to Wilson about the enduring popularity of the genre, and why you should be proud to call yourself a science fiction fan. Plus, the pair share loads of recommendations and explore sci-fi’s many different sub-genres, from climate fiction to cyberpunk.

You can learn more about Emily’s trilogy, The Sumerians, here.
