A group of spiky reptiles living on Clarion Island off the coast of Mexico has escaped extermination after it was discovered that they are not the invaders they had been labeled. Known as spiny-tailed iguanas (Ctenosaura sp.), it had been assumed they were introduced to the island by humans, but oh how wrong we were. […]
C/2025 A6 (Lemmon): Phenomenal Fleeting Photobomb Creates Spiral Over Brightest Comet
It is a good rule of thumb to try to see meteors with the naked eye. They move too quickly and they are too ephemeral to catch them with a telescope. Still, all good rules have exceptions, and this latest exception created a stunning mirage around Comet C/2025 A6 (Lemmon), as a red helix seems […]
Why Are Men Taller Than Women? Weirdly, We Don’t Actually Know
Men, on average, are about 13 centimeters (5 inches) taller than women, with sex hormones and growth genes thought to be the main drivers of this height difference. However, while numerous studies have sought to identify these male-specific genes, the long and short of it is that we still don’t really understand the genetic mechanisms […]
First Targeted Treatment For Dangerous Liver Disease Could Come From An Unexpected Source
Scientists could be on course to develop the first treatment with a chance of controlling and even reversing liver fibrosis, thanks to a discovery from a rather surprising source. Pigments extracted from the henna tree Lawsonia inermis, used for generations for coloring hair and decorating skin, have proven to be a promising drug candidate in […]
Mushrooms Could Beat Metal For Large-Scale Memory Storage And Processing
A popular mushroom species can be trained to remember past electrical states, allowing it to act as both a memory device and data processor known as an organic memristor. Scaling performance may be a challenge, but theoretically, the discovery opens the way to computers that consume fewer resources and might eventually be cheaper and certainly […]
Greenhouse Gases’ Heat Trapping Ability Hasn’t Saturated As Some Predicted – But Why?
Anytime global warming or climate change get mentioned online, you can expect a bunch of comments claiming to be able to disprove the whole concept, at least in relation to human activity. Most of these have been debunked, not just in detailed scientific papers, but by plenty of popular science websites, IFLScience included. There’s at […]
Did You Know The World’s Largest Waterfall Is Underwater?
Did you know the world’s largest waterfall is underwater? Us neither – every day’s a school day as they say. The tallest waterfall on Earth stands at a massive 3.5 kilometers (2.2 miles), next to which Angel Falls, the tallest uninterrupted waterfall over land, pales in comparison. So, where is this underwater behemoth? The rest […]
Video Game Study Found Out What People Do When The World Ends, And It’s Exactly What You’d Expect
There are few things more difficult than studying the end of the world, and how humanity would react before it. If you try when the world isn’t ending, then you probably won’t get an accurate impression, given that the world isn’t really ending. If you try while the world is actually ending, people won’t be that interested in […]

You Should Never Leave These Foods In Your Fridge Door (But We Bet You Do)
Fridges are kind of a triumph of design. There are shelves; there are crisper drawers; there are little spaces for individual eggs; a light that comes on only when you open the door and, if you’re feeling fancy, even an ice machine. But not everything about your fridge is so well thought-out. The shelves inside the […]
These Gullies On Mars Look Carved – We Might Finally Know What Created Them
Mars is a desert planet with dunes, canyons, and surprisingly fast winds. It is very cold, though, so it does not often get compared to desert planets of fiction, like Tatooine of Star Wars or Arrakis of Dune. But a mysterious feature made astronomers consider a parallel with the Dune planet, gullies carved in Martian […]
Potential Environmental Trigger For Autism Identified, 3I/ATLAS’s Tail Appears To Have Changed Direction, And Much More This Week
This week, almost 90 percent of US adults have at least one risk factor for a newly defined medical condition, the ancient Jomon of Japan might be one of the only groups of people outside Africa who had virtually no Denisovan DNA, and Iceland records its first-ever sighting of mosquitos in the country, meaning there’s […]
Spaghetti Has Inner Secrets We’re Only Just Learning About
Even in this modern world, there are still so many things science can’t explain. What goes on inside a black hole? Are we alone in the universe? What’s the secret to human happiness? And perhaps most importantly of all: why doesn’t spaghetti disintegrate when we cook it? It’s not a trivial question, even if it […]
How Far Back In Time Could You Go And Still Understand English?
Languages evolve over time, prompting a great question: How far back in time could you go and still understand English? If you were to speak to someone from the 1800s, or read a book from the same period, you would likely be fine. Sense and Sensibility (1811) remains comprehensible, for example, with some even claiming to be […]
We Now Know How The First People Reached America – And It Wasn’t On Foot
The first people to enter the Americas may have sailed from Japan around 20,000 years ago, according to a new analysis of prehistoric stone tools from 10 sites across the US. Until now, researchers had only uncovered a few tantalizing hints that humans had reached the American continent by this time, with ancient footprints in […]
Two Major Coral Species Now Functionally Extinct In Florida Keys, After Record-Breaking Marine Heatwave
A new study by scientists investigating the impact of 2023’s record-breaking marine heatwave on Florida’s coral reef has revealed that the event drove two of the area’s key coral species to functional extinction.

A “Super-Earth” In The Habitable Zone Is Half The Distance To Comparable Worlds
A newly discovered planet sits in the habitable zone of its star, where temperatures are right for liquid water if the atmosphere is appropriate. Based on the available data, GJ 251c is thought most likely to be a “super-Earth”, a rocky planet somewhat larger and more massive than Earth, but a sub-Neptune can’t be entirely […]
Adorable But Critically Endangered Bornean Orangutan Born In Conservation Success

How Did The FDA Settle On The “2,000 Calories Per Day” Guideline?
It is, these days, an overwhelmingly familiar sight: adorning every packet of food or drink, the little table of nutritional information. Snacks today are duty-bound to relate their concentrations of certain vitamins; to warn us of how much sugar and fat they contain; most of all, looming large above all other attributes, they must inform […]
Comet 3I/ATLAS Losing At Least Two Kangaroos’ Worth Of Dust Every Second
In a matter of days, Comet 3I/ATLAS will reach its closest point to the Sun. The third known interstellar object will reach its peak of activity, releasing gases and dust like it might not have done in tens of millions of years, or maybe even longer. Comparison between this interstellar interloper and the previous two […]
