There are four fundamental forces that describe how everything works, from black holes to radioactive decay to sounds coming out of your headphones. But this week we discuss hints that there is a fifth fundamental force of nature.

In the pod this week are New Scientist journalists Rowan Hooper, Penny Sarchet, and Valerie Jamieson. They ask whether physics is in crisis, given that it struggles to explain 95% of the universe, or if physicists are happy, because there is so much still to discover.

The team also discuss the creation of mouse-human chimeras, they reveal how kelp could help remove billions of tonnes of carbon from the atmosphere, and analyse whether dystopian science fiction has primed us to think that social distancing surveillance measures - such as the robot dog seen patrolling in Singapore - are too creepy. And there’s a swift discussion about the bird that sleeps on the wing and that has just returned to Europe from Africa. To find out more, subscribe at newscientist.com/podcasts.

As severe weather events around the world give us a very real taste of the devastating effects of climate change, we’re also getting a better understanding of what the future holds for our planet. The Intergovernmental Panel on Climate Change releases its big report on the physical basis of climate change next week - the team previews what’s to come. They also explain why a number of nations are now mixing and matching their vaccine doses in order to stop the spread of the covid-19 delta variant. For the first time, microplastics have been found in human placentas, and the team examines the possible health implications. They also learn about new technology which is being used to send hidden messages in the calls of whales and dolphins, and they get all Doctor Who when they find out about the existence of real life time crystals. On the pod are Rowan Hooper, Penny Sarchet and Matt Sparkes. To read about these stories and much more, subscribe at newscientist.com/podcasts.

The UK now has the highest number of covid-19 deaths in Europe, and worldwide, the total number of confirmed covid-19 deaths is second only to the US. So how did the UK get it so wrong? We discuss why slowness to get testing seems to have been a real problem, and if it is even possible to vaccinate against covid-19.

In the pod this week are New Scientist journalists Rowan Hooper, Penny Sarchet, and Adam Vaughan. They delve into the ethics of vaccine development, and why hopes of seeing one in September are now vanishingly unlikely.

They also discuss new research which suggests Parkinson’s disease may spread from the gut to the brain, they hear about why Mars’s moon Phobos may someday turn back into a ring around the planet, and they celebrate that astrophysicist Brian May - better known as the guitarist from Queen - has published a paper on asteroids. Not only that, but Greta Thunberg turns up on the new 1975 album. To find out more, subscribe at newscientist.com/podcasts.

Episode 293

The future of NASA and of US science is under threat, following cuts made by the Trump administration. Johns Hopkins University lost $800 million in grants this week which will impact the health of people all over the world. At the same time, there’s chaos at NASA where the budget is set to be cut in half, with multiple people losing their jobs overnight. What missions will we have to sacrifice - and will NASA survive?

As we pump ever increasing amounts of carbon dioxide into the atmosphere, some people argue this is actually a benefit to the world’s plant life. As carbon dioxide rises, photosynthesis can increase - but only up to a point. New research shows there’s a limit to this effect and many, many consequences. One study on trees suggests rising CO2 levels could impact the carbon storage capacity, and the lifespan, of the world’s forests.

Our understanding of memory has been flipped on its head. Researchers have been looking into a memory illusion that warps our perception of time. In a clever experiment, they’ve shown that experiencing something multiple times not only makes our memory of it stronger, but also makes us think it’s an older memory too. Find out what’s happening - and how there is no single thing as “memory”.

Chapters:

(00:21) The future of NASA

(6:52) Photosynthesis collapse

(19:59) The mystery of memory

Hosted by Rowan Hooper and Penny Sarchet, with guests Jacob Aron, Madeleine Cuff, Sophie Berdugo, Rob MacKenzie, Gustaf Degen, Ian Billick and Alex Easton.

The world, the universe and us - Weekly: Reversing blindness; power beamed from space; animal love languages
play

#237

Glaucoma, which can cause blindness by damaging the optic nerve, may be reversible. Researchers have managed to coax new optic nerve cells to grow in mice, partly restoring sight in some. How the treatment works through an eyeball injection and why, for humans, prevention and early detection are still the best options.

Black holes, just like planets and stars, spin. But they may be spinning a lot slower than we thought. When black holes gobble up matter around them, they start spinning faster and we’ve largely used this understanding to guess their speed. But new research also weighs the slowing effect of massive gas jets that black holes emit – revealing that many may have slowed dramatically since their births. How these new estimates of spin also offer insights into a black hole’s history.

What if we could generate solar power in space, far more efficiently than on Earth – and then beam it down to our houses? An MIT experiment has managed to do one of the most crucial steps of that science fiction-seeming process, converting electricity from a satellite into microwaves that were then successfully received by a collector in California. How these microwaves could supply the power grid on Earth and help ween us off of fossil fuels – if they can overcome some major hurdles.

Apes like to playfully tease each other, just like humans do. While their methods may be a bit different from ours – poking, hitting, pulling on hair and stealing – it looks like they’re often doing it for fun, rather than to harass or assert dominance. This new finding could explain why humans evolved to enjoy jokes.

Plus: A weird cooling quirk of Antarctica’s atmosphere; the microbes that make your tea taste delicious; and the flamboyant love languages of cuttlefish, scorpions and even dog-loving humans.

Hosts Christie Taylor and Chelsea Whyte discuss with guests Michael Le Page, Alex Wilkins and Chen Ly. To read more about these stories, visit newscientist.com.

#233

A cloned rhesus monkey named ReTro is said to be in good health more than three years after his birth – a landmark achievement, as no other rhesus clone has lived to adulthood.. However, the method used to clone ReTro used fetal cells, a method that cannot create identical clones of adult primates. The method could still be useful for medical research.

Fermented foods are meant to be healthy and good for our guts, but there’s a problem. Researchers have found antibiotic resistant bacteria in a small pilot study of some fermented foods. In vulnerable people, these bacteria could damage the gut and cause more severe health issues – and be resistant to antibiotic treatment. This ancient practice may need an update to deal with a modern problem.

Is it a black hole, is it a neutron star? No it’s a... mystery. A strange object has been found in the depths of space that could be the smallest black hole we’ve ever detected, or a neutron star that’s larger than we thought possible. Either result would be interesting, offering exciting new insights into our understanding of the universe.

A new type of computer promises to be more efficient than your standard PC. Normal Computing’s device uses the laws of thermodynamics – and tiny, random fluctuations in electrical current – to compute. And maybe most importantly, it’s already been used to solve some difficult problems.

Tardigrades are some of the hardiest creatures on the planet. These microscopic “water bears” can survive harsh conditions by entering a deep, dehydrated state of hibernation. And now researchers have figured out how they do it.

Hosts Timothy Revell and Christie Taylor discuss with guests Sam Wong, James Woodford, Alex Wilkins, Karmela Padavic-Callaghan and Chen Ly. To read more about these stories, visit newscientist.com.

The world, the universe and us - Dead Planets Society: Giving the Milky Way More Arms
play

05/14/24 • 37 min

Galaxies come in only a few shapes, which are all very round looking. You’ve got spirals and you’ve got blobs. Not content with this boring assortment, Leah Crane and Chelsea Whyte want to shake things up a bit.

First up they want to give our own spiral galaxy, the Milky Way, more arms. One, two... eight? As many as possible. But they don’t stop at “octogalaxy”. They also ponder on what it would take to defy the laws of physics and create a giraffe-shaped galaxy.

Aided by Vivian U, an astronomer at UC Irvine, the team discusses whether smashing galaxies together would help in their quest, how shooting black holes into orbit via rail gun may create interesting patterns and whether the galaxy sculpture can be made using dark matter.

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.

Episode 267

The remains of an ancient Neanderthal man discovered in France may be one of the last members of a lost line. Researchers analysing the DNA of the fossil nicknamed “Thorin” (named after the dwarven king in the Hobbit) made the surprising discovery that he’s possibly one of the last of his line. He may have been part of a group that lived in isolation for 50,000 years.

How can we tell climate change is to blame for specific heat waves, hurricanes, or other extreme weather events the planet has been hit by in recent years? That’s where attribution science comes in. Find out how the fingerprints of climate change could one day make it into your daily weather report.

Elephants, chimps and even chickens have shown signs of self-awareness. Even a fish, the cleaner wrasse, has passed the famous ‘mirror test’ in recent years. But new research on this territorial fish has found it can also use mirrors as a tool – to decide if they’re big enough to fight another wrasse. Learn more about how cleaner wrasse size themselves up before picking fights, and what this may say about their cognition.

Private astronauts on a SpaceX mission performed the first ever civilian spacewalk on Thursday. Hear reaction to the historic news and why their state-of-the-art spacesuits are grabbing people’s attention. Plus hear how researchers have created a “cloud atlas”, full of gorgeous pictures of the weird and wonderful – and informative – clouds that fill Mars’ sky.

Reporter James Woodford recently took control of one of the most advanced humanoid robots ever created. An energy company is helping NASA test a robot from its Valkyrie programme in Perth, Australia. James met the robot, nicknamed Val, and even helped use virtual reality tools to control her movements.

Hosts Rowan Hooper and Christie Taylor discuss with guests Alison George, Madeleine Cuff, Corryn Wetzel and James Woodford.

Would you feel uneasy or relieved to know that free will doesn’t exist? For those who have been fortunate in life, it may feel an attack to suggest they are not captains of their own ships - that their success was down to biological and environmental chance. But for others it may feel a lot more liberating.

Robert Sapolsky is an author, eminent neuroscientist and professor at Stanford University, known by many for his work studying baboons and human biology. But his latest book is much more associated with the field of philosophy. Determined: Life Without Free Will explores the notions of choice, responsibility and morality, arguing that free will does not exist and why acknowledging this should cause us to rethink the fundamentals of human society.

In this episode of CultureLab, Timothy Revell asks Sapolsky why humans are so-hardwired to believe that free will does exist, how our understanding of free will has shifted over the years and whether we could avoid societal collapse if everyone began believing their actions are not their own.

The world, the universe and us - #64: Earth Day rescue plan: climate change and biodiversity special
play

04/22/21 • 31 min

To mark Earth Day 2021, we’ve assembled a panel of experts to discuss climate change and biodiversity loss - “two runaway crises tightly interlinked that will mutually make each other’s effects worse”. New evidence shows 2021 really is a make-or-break year for the environment and the planet. In this episode the panel explores the disparity between our efforts to combat each issue, they explain how some attempts to help the environment can actually worsen the situation, and they discuss the limitations of carbon drawdown technologies. The discussion leans into the dangers of losing the Amazon rainforest, the importance of working with local communities, and the role billionaires play in advancing global climate goals. And while the scale of the problem seems insurmountable to many, the team says it’s important to remember that your actions are not futile - taking a personal stand and changing your habits is still absolutely critical. The Earth can recover, if we let it. On the pod this week: New Scientist journalists Rowan Hooper, Michael Le Page and Adam Vaughan, joined by Tilly Collins from the Centre for Environmental Policy and Bonnie Waring from the Grantham Institute for Climate Change and the Environment.
