Seasonal flu is a bit of a guessing game. A very scientific, high-stakes guessing game, but still. We can never know for sure exactly how a flu season will play out, so scientists make predictions based on the season in the opposite hemisphere of the globe, and use their best guesses of which virus strains […]

Why Did Prehistoric Mummies From The Atacama Desert Have Such Small Brains?
The Chinchorro culture that inhabited Chile’s Atacama Desert from about 7,500 years ago is famous for its mummies, which predate those from Ancient Egypt by several millennia. Scanning the heads of these wrinkled corpses, researchers have now revealed that the average Chinchorro individual possessed a brain that was about 12 percent smaller than that of […]
What Would Happen If A Tiny Primordial Black Hole Passed Through Your Body?
A new paper has explored what would happen if a tiny black hole were to pass through a human body. Rather than a disappointing “not much”, the physicist behind the paper specifically tried to determine the minimum size of such a black hole that would cause “significant injury or death” to the human unlucky enough […]
“Far From A Pop-Science Relic”: Why “6 Degrees Of Separation” Rules The Modern World
Suppose you’re given a message to be delivered to a specific person as fast as possible. Here’s the problem, though: you don’t personally know the recipient; you don’t have their address, only a general location; and they’re far away enough that personally going there and wandering about shouting their name is out of the question. […]
IFLScience We Have Questions: Can Sheep Livers Predict The Future?
Is it possible to predict the future by slicing open a farm animal and peering inside its liver? Scientists of the 21st century would surely be skeptical about approaching this question, but for the curious minds of ancient times, it was a tried and tested method for looking ahead and foreseeing what the gods had […]
The Cavendish Experiment: In 1797, Henry Cavendish Used Two Small Metal Spheres To Weigh The Entire Earth
If someone asked you to weigh the planet and you had not paid close attention in high school physics, you might have no idea where to begin. How do you measure something you are standing on? It is a bit like being told to weigh your own set of scales without having another set to […]
People Are Only Now Learning Where The Titanic Actually Sank
On April 15, 1912, an iceberg brought down a ship once thought to be unsinkable. The Titanic was the largest ocean liner of its time when it began its maiden voyage from Southampton in the United Kingdom to New York in the United States. Its journey ended in tragedy just four days into the Atlantic […]
A New Way Of Looking At Einstein’s Equations Could Reveal What Happened Before The Big Bang
The evidence for the Big Bang is overwhelming, yet we cannot truly describe what happens in that event. We cannot even call it a moment because time as we know it did not exist. Our science stops making sense a fraction of a second after it begins. The equations simply fail. But what if there […]
First-Ever Look At Neanderthal Nasal Cavity Shatters Expectations, NASA Reveals Comet 3I/ATLAS Images From 8 Missions, And Much More This Week
This week, research into the evolutionary origins of kissing has revealed that our ancient ancestors were smooching around 21 million years ago, new footage may be the first evidence of wild wolves using tools, and 14,400-year-old paw prints are the world’s oldest evidence of humans living alongside canine companions. Finally, we share an exclusive clip […]
The Latest Internet Debate: Is It More Efficient To Walk Around On Massive Stilts?
People over on Reddit are once again (see also: why we can’t power trucks with a big magnet) asking the big questions: is it more energy efficient to walk around on giant stilts? In a post to the “they did the math” subreddit, one Redditor asked the question, after seeing a video of members of […]
The Trump Administration Wants To Change The Endangered Species Act – Here’s What To Know
The Trump administration announced earlier this week its proposal to make changes to the Endangered Species Act (ESA), limiting protections given to plants and animals and boosting the influence of economic factors in decision-making. This isn’t the first time alterations have been made to the ESA; the previous Trump administration made changes to the act […]
That Iconic Lion Roar? Turns Out, They Have A Whole Other One That We Never Knew About
How do you tell large dangerous animals apart while staying safe? Well, one way for lions has been to identify them through their roar. For a long time it was believed that lions only had one kind of roar, a full-throated noise that was a pretty iconic part of the African soundscape. Now, thanks to […]
What Are Gravity Assists And Why Do Spacecraft Use Them So Much?
As this is written, the Jupiter Icy Moons Explorer (Juice) mission is taking images of interstellar comet 3I/ATLAS, providing an angle Earth-based telescopes can’t offer. Yet if you look at a map of the Solar System, you might wonder why on earth Juice is in this location, well-suited to spotting the cometary interloper as it […]
In 2026, Unique Mission Will Try To Save A NASA Telescope Set To Uncontrollably Crash To Earth
A two-decade-old NASA telescope is on an unstable orbit, and there is a 90 percent chance that it might come burning down in an uncontrolled reentry by the end of 2026. NASA has awarded a private contract to space technology company Katalyst to perform a never-before operation to save this orbiting observatory. The rest of […]
Blue Origin Just Revealed Its Latest New Glenn Rocket And It’s As Tall As SpaceX’s Starship
Last week, Blue Origin launched its first interplanetary mission, two spacecraft bound for Mars. It also performed its first successful landing of its New Glenn rocket’s booster stage. On the wave of that success, the Jeff Bezos-owned private space company has announced it will go bigger. It plans to have a more powerful version of […]
What Exactly Is The “Man In The Moon”?
We love seeing things in other things: rocks, houses, plugs, all become faces. In the sky, the constellations linked myths and legends with distant and often unrelated stars. A particular example of celestial pareidolia – the perception of a pattern in a random arrangement of stuff – is what in Western countries is referred to […]
45,000 Years Ago, These Neanderthals Cannibalized Women And Children From A Rival Group
Neanderthals in what is now Belgium may have eaten the weakest members of an enemy clan around 45,000 years ago. Analyzing the bones of these massacred victims, researchers have revealed that they all belong to petite females and children, suggesting that these individuals were specifically targeted by the cannibals. The rest of this article is […]
“Parasocial” Announced As Word Of The Year 2025 – Does It Describe You? And Is It Even Healthy?
It’s that time of year again, when the Cambridge Dictionary announces the word that it feels best defines the last 12 months. For 2025, the winner is, drumroll please… parasocial. Just as we eagerly anticipate the annual arrival of our Spotify Wrapped, we always look forward to these Word of the Year announcements. But the […]
Why Do Crocodiles Not Eat Capybaras?
The undisputed top chillers of the animal kingdom, capybaras seem to be pals with everyone and everything – even crocodilians, occasionally ferocious predators that aren’t known for their gestures of goodwill. But why is that? Capybaras (Hydrochoerus hydrochaeris) are the largest living species of rodent (real-life Rodents of Unusual Size). Native to much of South […]
Not An Artist Impression – JWST’s Latest Image Both Wows And Solves Mystery Of Aging Star System
From the very first images, JWST showed that it was going to be a revolutionary instrument, and yet it continues to surprise us. New observations from the infrared space telescope have upended previous observations of a relatively close star system. It has revealed a complexity that had not been seen before in spectacularly crisp new […]
