Many of us remember growing up with questionable toys that would not make it onto the shelves today – whether they would not be deemed appropriate for kids today or contained potentially harmful materials that made them a health risk. Now, a vintage toy set that was once listed as one of the “most dangerous […]

So-called dark comets exist in two classes, large objects in the outer Solar System and smaller ones closer to the Sun, a new paper reveals. Dark comets are not a form of dark matter, but objects with no visible tail or outgassing, but whose orbits reveal comet-style acceleration. It’s a category that includes ‘Oumuamua, the […]

Nuclear energy is a controversial subject for many people. Although traditional nuclear energy, derived from uranium or plutonium, has been hailed as a reliable, low-carbon energy source, it has also raised significant objections from environmentalists, the public, and policymakers alike. Many of these objections have related to nuclear energy’s overall safety, its high costs, limited […]

Seeing a fish floating vertically might normally be cause for concern, but in the case of Aeoliscus strigatus – better known as the razorfish or coral shrimpfish – swimming snout down is nothing to be worried about. So why exactly do they do it? Masters of disguise The answer lies in where these characteristically long, […]

A bunch of fishermen in the Dmanisi region of Georgia picked up an unexpected catch recently when they hauled in a stone tablet bearing an ancient inscription in a language that has never been seen before. Researchers aren’t entirely sure when the mysterious text was engraved or by whom, but suspect it probably dates back […]

It can be tricky to see sponges as animals, stationary and plant-like as they are, but they represent some of the longest-living animals on the planet. Arguably the most impressive can be found in Antarctica, where scientists estimate one specimen may be as old as 11,000 years. The sponge in question belongs to the species […]

On April 14, 1986, the Gopalganj district in Bangladesh was hit by a deadly hailstorm that would kill 92 people. According to the World Meteorological Organization’s World Weather and Climate Extremes Archive, the hailstones that fell from the sky that day weighed as much as 1.02 kilograms (2.2 pounds), earning the giant balls of ice […]

There are a lot of areas of physics that appear counterintuitive, with some of the most famous examples including wave-particle duality and time dilation. But you may feel like you have a pretty intuitive understanding of fairly simple macro objects, for instance, a pole. So here’s a question; when you take a long metal pole […]

From 1990 to 2020 the world got hotter and most of it also got drier. “Most” here not including the oceans. Areas meeting the definition of drylands have expanded by an area equal to almost three times that of India. The trend has been described in a United Nations report as revealing; “A global, existential […]

Scientists from the European Copernicus Climate Change Service (C3S) are ready to say that 2024 is going to be the hottest year our planet has experienced since records began. This is both surprising and concerning. Surprising because these records are usually awarded after the period has ended. Concerning because even without including data from December, […]

The expression “it’s like learning to ride a bike” is often used in situations where you never really forget the lesson. Once you know how to ride a bike, that’s it, you just know. But while you may know instinctively how to ride a bike, you probably don’t know the physics of it. For instance, […]

Ancient humans came together 35,000 years ago in the deepest, darkest part of a cave in what is now western Galilee, Israel, to hold ritualistic gatherings. This appears to be the earliest known example of such gatherings on the Asian continent. Discovered in 2008, Manot cave has a long history of associations with both humans […]

Ever noticed the appearance of mysterious and jelly-like green blobs or mats on your lawn or driveway after a rainy day? No, it’s not aliens, nor has someone done a very big sneeze near your house – it might just be Nostoc. What is Nostoc? Also known as troll’s butter or star jelly, Nostoc is […]

The Main Asteroid Belt is located between the orbits of Mars and Jupiter. The largest objects there have been known for hundreds of years, but new smaller rocks orbiting in this region are discovered all the time. A team has now pushed the discovery limit to smaller sizes, delivering the smallest asteroids known in the […]

Amid its colossal chunks of ice sheets, Antarctica harbors a land of fiery volcanism. Although the vast majority of these volcanoes are dormant, idle, or hidden beneath the ice, there is some speculation that they could be reawakened due to the melting of surrounding ice sheets. The last major melting event on Earth occurred between […]

Are praying mantises pretty smart? Do inchworms have the highest IQ? Or is it the humble bumblebee that beats out the beetles in the quest for the smartest insect? We take a closer look at which insects are truly in the running when it comes to smarts. Measuring intelligence in a non-human animal is a […]

Neolithic archers in southern Iberia were true masters of their craft, as evidenced by the discovery of Europe’s oldest known bowstring and fletched arrows. Found in a cave near Granada, Spain, the 7,000-year-old artifacts are fashioned from a range of unexpected materials that would have enhanced the power and precision of the ancient weapons. Originally […]

Eggs can come in a variety of sizes and flavors, just ask anybody who has tasted a penguin egg (once they get the horrendous taste out of their mouth, of course). The largest eggs still being laid today come from ostriches. The biggest of those eggs on record weighed in at an impressive 2.589 kilograms […]

Construction workers have stumbled across the ruins of a large pyramid along the side of a highway in Mexico. After being alerted to the discovery, archaeologists collected dozens of other artifacts from the site that will be closely studied in the lab over the next few months. The structure was unearthed in June 2024 during […]

They say opposites attract: Magnets’ north poles are drawn to south poles; Aziraphale is best buddies with Crowley; the sweetness of caramel is complemented by a pinch of salt. Nothing exemplifies this odd couple trope better than Ancient Greek mathematicians and particle accelerators. No, we’re not kidding. Come with us through two millennia, three continents, […]
