Scientists Discover "Zombie" Fungus That Seizes Control of Spiders, Suggest It Be Used for Human Medicine
While filming a TV documentary inside an old Victorian gunpowder store in Northern Ireland, scientists made an intriguing discovery: cave spider "zombies" that were infected by a "Last of Us"-like fungus.
In a study published last month in the journal Fungal Systematics and Evolution, as spotted by Live Science, scientists detailed the discovery of a "novel species" of fungus that infects "cave-dwelling, orb-weaving spiders," called Gibellula attenboroughii — a name in honor of British biologist and natural historian David Attenborough.
The scientists concluded that the "infected spiders exhibit behavioral changes similar to those reported for zombie ants," referring to an insect-pathogenic fungus that forces infected ants to leave their canopy nests and head to areas that are more suitable for fungal growth.
The way G. attenboroughii spreads is just as chill-inducing. The study authors suggest the fungus forces the infected spiders to crawl to more open areas where air currents can then disperse the spores — a fascinating new discovery fit for a dystopian TV series.
Study lead author and Center for Agriculture and Bioscience International researcher Harry Evans told Live Science that the spores penetrate the spider to infect the insect's equivalent of blood, compelling it to find open space. Then, a neurotoxin kills the spider once it reaches a spot in the open. An antimicrobial substance also preserves the corpse, allowing the fungus to absorb its nutrients.
The cycle then repeats with the fungus growing long — and terrifying-looking — structures out of the spider's body.
Despite the frightening optics, Evans told Live Science the substances the fungus produces could be a "medical treasure chest" with a range of possible applications in human medicine, including antibiotics.
More generally, the discovery highlights how much there's still to cover in the wild world of "zombie" fungi.
"There's a lot more fungi to find," Evans told Live Science. "The fungal kingdom could be up to 10, 20 million species, making it the biggest kingdom by far, but only one percent have been described."

If books could kill: The poison legacy lurking in libraries
The Victorians loved the colour green. In particular, they loved a vibrant shade of emerald created by combining copper and arsenic, which was used in everything from wallpaper to children's toys. "This colour was very popular for most of the 19th Century because of its vibrancy and its resistance to light fading," says Erica Kotze, a preservative conservator at the University of St Andrews. "We know that many household items were coloured with arsenic-based green pigments. It was even used in confectionery." The trouble is, the combination of elements used is toxic and that's still a problem more than a century later. And it's a particular problem when it comes to old books. Victorian bookbinders used arsenic as well as mercury and chrome to create striking covers. And unlike domestic items, books have survived in archives around the world, creating a 21st Century problem from 19th Century fashion. Prolonged exposure to multiple green books can cause low level arsenic poisoning. Long-term exposure can cause changes to the skin, harm to the liver and kidneys and a reduction in red and white blood cells, which can lead to anaemia and an increased risk of infections. In 2019, an attempt to tackle the problem was set up in Delaware between the Winterthur Museum and the state university. The Poison Book Project tested books and drew up a list of titles which are potentially harmful to humans. These included four books in the National Library of France, which were immediately withdrawn. Inspired by this, Erica Kotze called on her colleague Dr Pilar Gil, who trained as a biochemist before working in Special Collections at the University of St Andrews. Dr Gil took a practical approach to surveying the thousands of historic books in their collection. "The most important thing was to find a non-destructive, portable instrument that could tell us if it was a poisonous book or not," she says. She rule out X-ray technology because of the fragile nature of the books being examined and instead looked to the geology department. They had a spectrometer - a device that measures the distribution of different wavelengths of light - for detecting minerals in rocks. "Minerals and pigments are very similar," says Dr Gil, "so I borrowed the instrument and started looking for emerald green in books." She tested hundreds of books and then realised she was looking at a breakthrough. "I realised there was a distinctive pattern to the toxic ones. It was a 'eureka' moment. I realised it was something that no one had seen before." The next task was to speak to the physics department to build their own prototype. Dr Graham Bruce, senior research laboratory manager explains how it works. "It shines light on the book and measures the amount of light which shines back," he says. "It uses green light, which can be seen, and infrared, which can't be seen with our own eyes. The green light flashes when there are no fragments of arsenic present, the red light when there are pigments." The new testing device is smaller and will be less costly to produce and use than a full-scale spectrometer It has already been used to survey the thousands of books in the St Andrews collections and in the National Library of Scotland, and the team hope to share their design with other institutions around the world. "We're lucky as a large institution to have expensive kit, so that we can test 19th Century potentially toxic books," says Dr Jessica Burge, deputy director of library and museums at the University of St Andrews. "But other institutions with big collections may not have those resources, so we wanted to create something which was affordable and easy. It doesn't require a specialist conservator or analysis, and it's instant." It's also a problem which isn't going away. If anything, toxic books will become more harmful as they get older and disintegrate. Identifying them means they can stored in a safe way and still enjoyed with controlled access and precautions such as wearing gloves. "It will continue to be a live issue," says Dr Burge. "But I think that the biggest issue for institutions at the moment is that any book that's got a green cover from the 19th Century is being restricted because they don't know. "And as libraries and museums, that's not really what we're about. We want people to be able to use the books and help bring back access to collections, rather than restricting their use."

The Climate Solution Hiding In Plain Sight
We're drowning in climate headlines. Every week brings more reports about disappearing species, collapsing ecosystems, or yet another environmental tipping point. It's exhausting. And it's easy to feel like the damage is too big, too complex, or too far gone to fix. That's what makes Ocean with David Attenborough—the new documentary directed by Toby Nowlan and narrated by Sir David Attenborough—so powerful. It doesn't offer false comfort or vague inspiration. It presents a clear, science-backed message: the ocean is more resilient than we thought, and protecting it is the most powerful thing we can do right now to restore the health of the planet. Dr. Enric Sala has spent the last 15 years proving that point. Once a university professor, Sala left academia after realizing he was spending his days documenting the slow death of the sea. He now leads National Geographic's Pristine Seas initiative, which combines exploration, policy, science, and storytelling to create marine protected areas (MPAs) around the world. So far, his team has helped establish 29 of them—covering an area larger than the Amazon rainforest. The findings so far are staggering. Fully protected marine reserves quickly regenerate. Fish populations can increase fivefold. Coral reefs damaged by bleaching events often recover in a few short years—if given the chance. I first met Dr. Sala and saw him speak in 2019 at the National Geographic Explorers Festival in Washington DC. I had a chance to sit down recently with Sala and Nowlan, to talk about this documentary and what they hope the audience will take away from watching it. 'The resilience is extraordinary,' Sala told me. 'Everywhere where there is fishing and you create a [marine protected] area, marine life comes back. That's universal.' These aren't isolated pockets of recovery. From the Southern Line Islands to the coasts of California, the pattern is the same: when you stop taking, the ocean gives back. A bait ball in the open ocean near Azores. Silverback Films and Open Planet Studios/Doug Anderson Despite these results, just 3% of the global ocean is fully protected today. Scientists say we need to protect at least 30%—both land and sea—by 2030 to maintain a livable planet. That 30x30 goal has been endorsed by governments, conservationists, and NGOs around the world. But Ocean isn't a policy documentary. It's not filled with charts and legislative jargon. It uses stunning visuals and emotional storytelling to make the science real—and personal. The film's message is direct: saving the ocean isn't just a climate issue. It's a life support issue. Half of the oxygen we breathe comes from the sea. The ocean regulates temperature, absorbs carbon, and feeds billions. If it collapses, it will have a cascading effect that collapses everything else with it. One thing that makes Ocean different from other environmental films is its focus on a single, proven action. While many documentaries leave viewers overwhelmed with advice—buy local, drive less, eat plant-based—Ocean makes a case for one big move: expand marine protection. 'We wanted to focus on one solution,' Sala explained. 'There is one proven solution that works everywhere… that actually can be applied by governments, by communities, by anybody.' That simplicity is what gives the film power. It shows that this isn't just about global policies or top-down mandates. Coastal communities can start small, protecting local waters. Governments can scale efforts. Even viewers far from the sea can raise awareness and support legislation to help the cause. The film is also shaped by director Toby Nowlan, whose credits include Planet Earth II and Our Planet. Nowlan has spent two decades filming the rarest, most vulnerable wildlife on Earth—including securing the best footage ever captured of the critically endangered Javan rhino. With Ocean, he wanted to make one message stick: protecting the sea works. It's not theory. It's happening now. That's why having Attenborough narrate the film matters. His voice has become a universal symbol of trust in nature storytelling. His presence here elevates the message, giving it weight at a time when public trust is rare and essential. One of the moments that stuck with me most in our conversation was Sala's reminder that this isn't just about the Arctic or the Great Barrier Reef. 'If you live on the coast, you can be the person who leads your community to protect your ocean backyard,' he said. That line matters. It reframes the ocean as not just a remote wilderness, but a shared resource that touches every life—no matter where we live. We don't need another film telling us how bad things are. We need stories that show us how to fix it. Ocean with David Attenborough does exactly that. It's beautiful, emotional, and urgent—but also deeply practical. The science is real. The path is clear. And the results are already visible in every corner of the sea that's been given time to heal. If governments follow through on the 30x30 promise—and if communities join the push—we could see the greatest comeback story the natural world has ever told. And it starts with protecting what's below the surface. Check out Ocean with David Attenborough for yourself. It is available now to stream on Disney+ and Hulu.

These are the best times to view June's strawberry moon
These are the best times to view June's strawberry moon A strawberry moon will dazzle skywatchers June 11. This year's strawberry moon will be a micromoon – which means it will appear dimmer and smaller than usual – and will be at its fullest at 3:44 a.m. ET, according to NASA. But because it's so early in the day, the best time to view the moon will be June 10, when it rises at sunset, according to LiveScience. The moon is expected to be a shade of gold rather than a vibrant shade of red like a strawberry, if weather conditions allow. The spectacle marks the last full moon before the summer solstice, when we officially say goodbye to spring. The moon also will appear about 14% smaller and 30% dimmer because it will be near its farthest point from Earth. Why is it called the strawberry moon? According to the Almanac, the name "strawberry moon" comes from the Native American Algonquian tribes, who lived in the northwestern United States. The Ojibwe, Dakota and Lakota tribes also used the name, which marked the wild strawberries in June. Where to view the strawberry moon June's full moon will be among the lowest in the sky of the year because of its low arc. Its moonlight will reflect the Earth's atmosphere, giving it a yellow or orange tint. On June 11, the full moon rises in the east shortly before sunset, which makes it the best time to see it from North America. Check the moonrise and moonset times in your location, then pick a site where you can see the eastern horizon at a low angle. You can use an online tool from The Old Farmer's Almanac to determine the local moonrise and moonset times. Try searching your city or ZIP code here. June's phases of the moon The moon takes about 29½ days to revolve around Earth, which is called a lunar cycle, according to the Lunar and Planetary Institute. As the moon moves through its various stages, it experiences several phases of partial light. These range from a banana-shaped crescent moon, a D-shaped quarter moon and a nearly full gibbous moon. When are the full moons in 2025? There are seven full moons remaining this year; three will be supermoons.
