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 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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

Moss spores have reproduced after nine months on the International Space Station (ISS), an announcement that sounds more impressive when you learn they were on the outside, exposed directly to the perils of space. Although single-celled organisms have demonstrated the same capacity previously, this is the first time a land plant has shown such powers […]

In 2017, the US’s Advanced Aerospace Threat Identification Program (AATIP), and the related Advanced Aerospace Weapons System Application Program (AAWSAP) were made public for the first time following an investigation by the New York Times.  The programs, funded by the Defense Intelligence Agency (DIA), were pretty out-there. Operating between 2007 and 2012, AATIP investigated unexplained […]

Exploring new caves during the Upper Palaeolithic was fraught with danger, which is why one group of ancient humans in Italy made sure to take their trusted four-legged companion with them when they stepped into the darkness. Analyzing the fossilized foot and paw prints left behind during this subterranean excursion, researchers say that these 14,400-year-old […]

The Grand Canyon is so immense and otherworldly that it can feel distant from the day-to-day life of most humans. But for some people, this awe-inspiring natural wonder is their ancestral home. Eleven tribes have deep historical connections to the lands associated with or bordering the Grand Canyon National Park, according to the National Park […]

To say it’s been a bit wet in Southern California of late would be something of an understatement. At the end of last week, a powerful atmospheric river dumped an extreme amount of rainfall on the region, including in Death Valley. According to a Facebook post from Death Valley National Park, Furnace Creek – which […]

“Well, why not call it The Big Chill? Or the Nippy Era? I’m just saying, how do we know it’s an Ice Age?” “Because of all the ice!” That’s the interaction between two Macrauchenia that kicks off Ice Age, everybody’s favorite squirrel-led foray into the Pleistocene. It touches on an interesting point, really, because although […]

For the first time, the effects of a geomagnetic superstorm on the Earth’s protective plasmasphere have been observed in detail. The storm in question compressed the plasmasphere by 80 percent, leaving us to wonder what even larger storms of the past did. The auroras of May 10-11, 2024, were almost certainly seen by more people […]

To our best of our understanding, the Moon formed from Earth following a colossal impact. A Mars-sized world we nicknamed Theia slammed and merged with the primordial Earth, throwing material into space. Some fell back onto the planet, while some spread out and formed the Moon. New analysis is providing novel insights into Theia and […]
