The Aztecs and the Celts were separated by an entire ocean and several millennia, which means they never met and had absolutely nothing to do with other. Despite this, their respective beliefs around death and the afterlife have now become fused to create both Halloween and the Day of the Dead (or Día de los […]

While the night sky might be set aglow with fireworks and bonfires in the UK next Wednesday, there’s another dazzling sight that evening that you’ll be able to see across the globe: the biggest supermoon of the year. If you’re unfamiliar, a supermoon is the name for when a full Moon happens at the same […]

If you’re trying to find a date, you want to look your best, right? Snazzy outfit, slick hair, makeup on point – whatever it takes to get the best choice of partner in the Grand Annual Orgy. Sound familiar? Well, it would if you were a toad. “Asian Common Toads (Duttaphrynus melanostictus) [are] an explosive […]

Our interstellar visitor is visible again after reaching its closest approach to the Sun yesterday. The PUNCH mission, a group of small satellites studying the Sun, spotted comet 3I/ATLAS as it came out of the Sun’s glare. The interstellar comet, the third known object formed in another star system to be tracked through our Solar […]

The bowhead whale is the world’s longest-living mammal, sometimes making it to a staggering 200 years old. How does it do it? A new study sheds some light on the secrets of this curious cetacean’s extreme longevity – and it could have ramifications for how we tackle aging in our own species too. As well […]

US President Donald Trump has revealed on social media that he has instructed the Pentagon (now known as the Department of War) to resume nuclear weapons testing in the United States for the first time in 33 years. According to Trump, the decision to conduct the highly controversial tests stems from a need to keep […]

Two paleontologists think they have settled a long-standing debate as to whether certain fossils from the very end of the Cretaceous represent a distinct species of small tyrannosaur, or juvenile T. rex, as many had assumed.  Their evidence relies on one of the pair of “Dueling Dinosaurs”, fossils that show a Triceratops fighting for its life […]

At IFLScience, we often like to talk about the Mantelpiece Of Dreams, a line-up of rare geological trinkets we’d like to shine down on us as we sit on the sofa (were it not for, you know, ethics). London Natural History Museum’s Professor Paul Barrett said he’d like a triceratops skull (nice), our own Eleanor […]

On October 19, South Australian vet Dr Andrew Melville-Smith’s newly collected car was struck by something, leaving damage unlike anything repairers have seen before. The South Australian Museum has requested access to the car to collect samples, and suspects this may be the first recorded case of a meteorite striking a car while it was […]

There’s always a lot going on in the deep ocean, but anyone who had “carnivorous ‘death-ball’ sponge” on their bingo card for 2025 deserves to win the prize. It’s one of 30 new species discovered by researchers exploring the deep dark depths of the Southern Ocean, some of them pretty peculiar – even for the […]

Chimpanzees at Uganda’s Ngamba Island Sanctuary can do what was once considered an exclusively human trait: form expectations on the basis of evidence, but revise them on learning new facts. Responding to evidence is an essential skill for the survival of any animal, but given how often humans neglect our supposed superpower, seeing another species […]

Meteor showers are the product of comets or asteroids dropping debris on their orbit. Once these debris streams cross the Earth, they burn up in the atmosphere, creating the shooting stars that we know and love. Many famous comets are responsible for famous showers, but the most prolific seems to be Comet Encke. It might […]

Genetic analysis of the hoiho, also known as the yellow-eyed penguin, has revealed that this species is in fact made up of three distinct subspecies – knowledge that could be crucial in preventing these rare and notoriously shy birds from going extinct. Found solely on the New Zealand mainland and Enderby and Campbell Islands, the […]

Being allergic to other people is one thing (and it sounds terrible, honestly). But imagine if the opposite were true – and everybody else were allergic to you. It sounds like the monkey’s paw interpretation of an asthmatic’s lament, but it’s an oh-so-real phenomenon. It’s called “People Allergic To Me” – often shortened to PATM […]

The creation of art has historically been thought of as a distinctly Homo sapiens behavior, but the recent discovery of a crayon-like piece of ocher that’s at least 42,000 years old adds to a growing body of evidence suggesting that our Neanderthal cousins also dabbled in a bit of symbolism. Researchers came to this conclusion […]

This month, we’ve been diving into one of the world’s most famous mysteries: the Loch Ness Monster. From its 1930s media debut to AI-generated “cryptids” reshaping modern folklore, we’re exploring how technology and storytelling keep legends like Nessie alive. And in our new documentary, we head to Loch Ness ourselves, speaking to experts, monster hunters, […]

An enormous area of the Earth’s crust has torn and slumped, dropping about 5 kilometers (3 miles). We’ve only just noticed because this is happening beneath the Pacific Ocean, but what sounds alarming could eventually end one of the planet’s most dangerous earthquake fault lines. The San Andreas Fault gets most of the USA’s attention […]

Stars like our Sun turn into red giants as they run out of hydrogen to fuse at their core. As the star continues to age, it will blow out its outer layers until the only thing that remains is an exposed core, a white dwarf. Before getting to the white dwarf state, Sun-sized stars can […]

As physics has its atoms, so math has the primes: numbers that are indivisible into any smaller constituent pieces. When we first learn about them, some time in grade school, they’re usually presented as an interesting little aside – strange blips in the number line that might occasionally make long division a bit more difficult, […]
