Weekly: Ultra-processed foods not so bad?; Another milestone toward fusion power; Mapping the genes we know nothing about

#210Ultra-processed foods are bad for us and we should avoid them at all costs – right? Well, it’s actually not as clear cut as that.The foods may actually form a much more important part of healthy diets than we release.  Nuclear fusion, which could some day offer a low-waste source of clean power, is one step closer to becoming viable. Last year scientists managed to get more power out of a fusion reactor than they put in – a huge breakthrough for the technology. And this year they’ve done one better, squeezing even more power out of it.There’s a lot that’s “unknome” about the human genome. More than 20 years since we discovered humans have just 20,000 different genes, we still don’t have a clue what thousands of them even do. A project is now finally looking at the proteins that science forgot.We’re getting 70s space race vibes. Russia has launched its first mission to the moon in nearly 50 years – just behind India’s Chandrayaan-3 spacecraft, which entered lunar orbit earlier this week. With both heading to the moon’s south pole, who’s going to get there first?Plus: a potential vaccine for the virus that causes mononucleosis – often called “the kissing disease” – and is linked to multiple sclerosis; whether robots are better than humans at the very CAPTCHA tests designed to block robots; and the slightly gross treasure hiding in 200-million-year-old fossilised poop.Hosts Timothy Revell and Chelsea Whyte discuss all of this with guests Grace Wade, Matt Sparkes, Michael Le Page and Leah Crane.

Weekly: Surprise superconductor claims put to the test; Alzheimer’s test goes on sale; how NASA (briefly) lost Voyager 2

#209The saga of the room-temperature superconductor continues. The creators of a new material called LK-99 maintain that it perfectly conducts electricity at room temperature and pressure and so other scientists are racing to try to test it for themselves. If the findings are true it would be transformative to science and technology. It’s not just researchers, however, who are testing the material, citizen scientists are also trying to create it at home. Early results are now in.There’s a plan to pump millions of tonnes of carbon dioxide into the seafloor off Canada’s west coast, but some worry that this could trigger earthquakes. A new study works out just how likely that would be.Earth to Voyager, this is NASA – do you copy? NASA has lost contact with the Voyager 2 space probe but all is not lost. The team discusses the future of the mission, as well as that the Euclid space telescope has just come online and started sending back its first images.A blood test for Alzheimer’s has gone on sale that may indicate your risk of developing the disease before symptoms show. But how accurate is the test? And if you find out you’re at risk, is there anything you can do about it? Plus: How the foundations of your house could store energy, how the Maillard reaction – responsible for the deliciousness of toast – can happen on the ocean floor, and the discovery of the world’s oldest jellyfish fossil.Hosts Timothy Revell and Christie Taylor discuss all of this with guests Karmela Padavic-Callaghan, Clare Wilson, Leah Crane and James Dinneen.

Weekly: Cheaper cures for many diseases; How to understand the superconductor ‘breakthrough’; Hear a star twinkle

New Scientist Weekly #208Better and cheaper treatments for everything from sickle cell disease to ageing should come as a result of a new technique for delivering mRNA to blood stem cells. The technique has been adapted from the technology in mRNA covid-19 vaccines and could even be used for doping in sport.Controversial claims of a superconductor that works at room temperature and pressure have ignited heated discussion this week. Such a finding would be revolutionary, with implications for transport, medical science and even nuclear fusion. But is it too early to celebrate this new discovery?Scientists are scrambling to save coral in the Florida Keys, where record sea temperatures are threatening the entire ecosystem. The coral and their symbiotic algae are being moved using a “coral bus” to off-shore nurseries in the hope of reestablishing them after the heat wanes. Genetic research could be instrumental in saving the reefs.Ever wondered what a star’s twinkle sounds like? Astronomer Evan Anders has developed a new way of modelling the movement of gases inside stars, giving us a glimpse (with our ears) at how they are built on the inside, how they spend their lives and evolve…Most of us are heavy-handed when it comes to estimating the weight of our… hands, something researchers have struggled to put their finger on. The strange phenomenon, where we misjudge the weight of our own body parts, could have an evolutionary explanation.Hosts Christie Taylor and Sam Wong discuss all of this with guests Michael Le Page, Karmela Padavic-Callaghan, Sofia Quaglia and Jason Murugesu.

CultureLab: Oppenheimer – The rise and fall of the “father of the atomic bomb”

First J. Robert Oppenheimer created the weapon, then he fought for years to warn of its dangers. During the second world war, the so-called “father of the atomic bomb”, led a team of scientists in the US in a race against Nazi Germany to create the first nuclear weapon. Then it was used to kill thousands in Hiroshima and Nagasaki in Japan.In Oppenheimer, Christopher Nolan’s new 3-hour blockbuster, the film focuses on the years that followed and how the physicist’s campaigning ultimately led to his downfall.In this episode of CultureLab, Christie Taylor speaks to Kai Bird, a journalist and historian who co-authored the book that was the main source material for Nolan’s film – American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer.To read about subjects like this and much more, you can subscribe to New Scientist magazine at newscientist.com.Links and info:Check out our review of Oppenheimer, by Simon Ings.

Weekly: How to measure consciousness; Nature-made graphene; New sabretooth cats

New Scientist Weekly #206A major theory of consciousness is being put to the test with brain scans. Integrated information theory proposes a value called "phi" to represent consciousness and in a new experiment, it seems to work. Does the discovery bring us any closer to solving the elusive “hard problem” of neuroscience? Graphene has been hailed as a super material since its synthesis in 2004. But, unbeknownst to us, nature has long-been producing graphene, right under our noses. Understanding natural graphene production could revolutionise the way we create this remarkable material.A roarsome discovery of two previously unknown sabre-toothed cat species in South Africa provides insights into their cheetah-like and leopard-like lifestyles. The finding challenges our long-held beliefs about these ancient felines. Could chargrilled mushrooms be the key to fireproofing our homes? A team in Melbourne, Australia, unveiled a fire-resistant material created from the mycelium of edible mushrooms this week. With remarkable flame resistance and environmentally-friendly properties, the approach looks promising. Finally, some intriguing space discoveries, including the Janus star, with its unique hydrogen-helium split surface, a giant exoplanet called PDS 70b, which reveals a potential sibling forming in its orbit, marking the first time two planets have been found to share an orbit, and the LEGO robot creating DNA machines.Hosts Timothy Revell and Christie Taylor discuss all of this with guests Clare Wilkins, Corryn Wetzel and Alex Wilkins.
