Another twist has been added to the puzzling mix that is early human ancestry with evidence that one of the most complete pre-human fossil skeletons we have found doesn’t belong to any recognized species. The team who made the discovery say they don’t know where StW 573, nicknamed Little Foot, fits from an evolutionary perspective, […]

Arctic animals are some of the most hardy on Earth, with special adaptations that help them survive freezing temperatures, vast sea ice, and long periods with nothing to eat. Among these adaptations, the Arctic fox possesses beautiful white fur, helping to blend in with the snowy background. But did you know that some of these […]

Analysis of data from almost 20,000 pregnancies in Canada has revealed that getting a COVID-19 shot is a great idea for pregnant people – not just for their health, but the baby’s too. As well as being linked to a lower risk of hospitalization and serious illness, vaccination was also found to be associated with […]

There are few things more pleasing to your average mathematician than when a result surprises you. Take e, for example – a transcendentally irrational number equal to a little more than 2.7 – and raise it to the power of π multiplied by the imaginary unit i. Add one to your total, and you get… zero. […]

At 4,100 meters (13,450 feet) beneath the ocean’s surface, scientists witnessed a never-before-seen behavior in a deep-sea cephalopod: an unknown species of whiplash squid burying its head into the muddy seabed with its tentacles rigidly poking out like chopsticks.  The researchers can only speculate on the purpose of this mysterious behavior in an undescribed species, […]

Coffee, probably the world’s favorite perker-upper and pooper-shaker, can have surprising benefits to those with severe mental illnesses, a new study has found. So long as you don’t overdo it, it seems the beverage can slow down the telomere shortening that diseases like bipolar disorder and schizophrenia can cause, taking roughly half a decade off […]

Pet nutrition has gotten complicated in recent years. There’s the ethics of where that meat comes from (David Attenborough’s OCEAN revealed how Antarctic krill is supplementing pet food). Then there’s the matter of whether raw meat is safe, or if pets can be healthy on a vegan diet. Owners put a lot of time, effort, […]

“The cosmos is within us. We are made of star stuff. We are a way for the universe to know itself,” Carl Sagan famously said in the 1980 TV series Cosmos. Forty-five years later, the quote has not lost its incredible impact on how profound our curiosity about the universe and our place in it […]

Lonesome George was an endling, the last of a rare subspecies native to a far-flung island in the Pacific. When he died, the subspecies died with him, but his legacy still lives on (and not just in the form of his stuffed taxidermized body). This truly unique animal was a Pinta Island tortoise (Chelonoidis niger […]

Bermuda is an island remnant of a volcano active 30-35 million years ago. However, it lacks the familiar features of other volcanic islands. Seismic waves reveal a unique structure that two scientists say explains these differences, but the theory of mantle plumes will need to be rewritten to understand how it happens. When hot plumes […]

Time is relative. The ticking of the clock, even of the most precise clocks we can make, does not exist in an absolute. It depends on the gravity you are experiencing and on your speed. Being on the surface of a sizable planet moving at high speed through space, spinning around a yellow star and […]

“Necrobotics” is a ghoulishly named field of research that uses the bodies of dead animals as robot parts. In the latest step toward creating the walking dead, researchers at EPFL in Switzerland have turned leftover crustacean tails into surprisingly effective robots. The engineers began by collecting the exoskeletons of langoustine (small lobsters also known as […]

Italians are known for their food, architecture, and longevity (among other things), with the Mediterranean diet often cited as a major contributor to an extensive lifespan. Yet new genetic research reveals that Italians who reach the age of 100 may in fact have their ancient hunter-gatherer DNA to thank. The rest of this article is […]

We are just days away from interstellar comet 3I/ATLAS’s closest approach to Earth, so it is not surprising that this fascinating space rock has gotten more attention. Observatories on Earth and in space have been able to study it without any risk of getting too close to the Sun, and new details and beautiful images […]

Here at IFLScience, we work hard to convince you that bears aren’t actually just a guy in a bear suit, but every so often, a video comes along that really doesn’t help our cause. The latest incident? Two young bears that appear to be playing seesaw with a tree branch. The stars of the video […]

Human toes, long removed from their tree-gripping days, are mostly noticed only when they are stubbed or exposed in sandals. The rest of this article is behind a paywall. Please sign in or subscribe to access the full content. Losing the ability to grip branches with them may seem like a backward step, given how […]

A large mass of granite that has been slowly releasing heat has been discovered buried beneath a crater on the Moon. This is not science fiction. It is ancient volcanism. The Moon once had lava fields and eruptions, but astronomers had never actually identified a more traditional Earth-like volcano until they examined what lay beneath […]

Back in 1967, the Soviet Union celebrated its 50th anniversary. As well as events on the ground, part of these celebrations involved a stunt to be carried out in space, which ultimately ended in the unnecessary death of cosmonaut Vladimir Komarov, who became known as “the man who fell from space”. The plan was to […]

Trekking nearly a whole day by plane to Australia might seem like a long-haul flight, but that’s got nothing on what the common swift is capable of. Lots of us get pretty restless after just a few hours, and we’re just sat on our asses. Imagine having to hold your arms out to the side […]

This week, a first-ever sauropod fossil with melanosomes suggests Diplodocus may have had a speckled color pattern, a new report outlines the priorities for a NASA-led human mission to Mars, and a new study has found that scheduling cancer immunotherapy in the morning may lower the risk of death by up to 63 percent. Finally, […]
