Blue is a relatively rare sight in living things. Green blankets much of the world, yellow and orange frequently pop up in plants and animals, while reds and pinks also find their time to shine. Meanwhile, blue is confined to just a meager selection of flowers, the odd eccentric bird, and a few freaky frogs. […]

When the ancestors of terrestrial life on Earth crawled or slithered out of the sea, they formed the starting point for many of the world’s species. Some of these species even made the return journey back into the water from a life on land. Now, a new study has taken a closer look at explaining […]

It’s nearly December, which – if you’re a tween in Australia – means it’s just weeks until your TikTok and Snapchat accounts go dark. The nation down under is about to become the world’s first home of a total ban on social media for under-16s, with the blackout set to kick off on December 10. […]

A new pre-print paper suggests that our latest interstellar visitor, comet 3I/ATLAS, may be headed for one final close encounter before it departs our Solar System in 2026. The paper, which focuses on dynamical simulations of the object, also attempts to look at the course 3I/ATLAS will take on departure, and the path that brought […]

Until recently, it was widely accepted that the earliest members of the Homo lineage were the first hominids to hunt. In particular, Homo erectus – which emerged around two million years ago – is typically credited with developing the taste for meat, yet new studies have begun to challenge this narrative, suggesting that our ancestors […]

Fort Knox is synonymous with gold. Lots of gold. But this Art Deco castle of concrete and granite is not actually the world’s largest depository of monetary gold on Earth. That title belongs to another US building in a far less conspicuous location. If you’ve ever wandered through downtown Manhattan, you may have walked right […]

A new mRNA vaccine against the flu has proven itself more effective than existing vaccines in a new clinical trial. The Pfizer-developed vaccine was found to be 34.5 percent more effective than current vaccines at preventing illness caused by influenza A in a trial of over 18,000 people. Though the new vaccine was associated with […]

Have you heard that dodo meat tasted foul? Loathsome, even. You’re not alone. It’s a strangely prevalent rumor, given that nobody alive today has ever eaten one. However, it’s quite possible that this “fact” is one that got lost in translation. Known to science as Raphus cucullatus, dodos also went by the nickname “wallowbird”, said […]

An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, first made over 60 years ago. When an object approaches the speed of light (let’s call the object a spaceship, for ease), a number of strange things take place. According to our best classical model of […]

Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, scientists have demonstrated time and time again how correct these theories are. Still, we know that they have limitations. They do not work together well, especially in two particularly important areas: black holes and the Big Bang. The rest […]

The first person known to have been infected with the H5N5 strain of avian influenza has died, the Washington State Department of Health announced Friday.  The rest of this article is behind a paywall.

Worrying levels of “forever chemicals” were detected in the waters of certain pockets of North Carolina in recent years. These human-made pollutants appeared everywhere, from rivers and sewers to drinking water. Now, a new study may have uncovered the culprit. “Forever chemicals” is the nickname given to PFAS, a synthetic group of compounds added to […]

From October 2007 until mid-2022, the Atacama Cosmology Telescope (ACT) looked at the millimeter and microwave universe. It discovered the most extreme galaxy cluster and many other peculiar things, though its true focus has always been studying the cosmic microwave background (CMB).  This is the light echo of the Big Bang, the first light that […]

The Hayli Gubbi shield volcano, thought to be dormant since almost the last ice age, has erupted, and the volcanic plume is reaching heights at which intercontinental aircraft fly. Hayli Gubbi is located in the Afar region of Ethiopia where the Arabian tectonic plate meets the Nubian and Somali parts of the African Plate, creating […]

There are a number of candidates for the title of the quietest natural place on Earth. It’s difficult to pinpoint the absolute quietest natural location, as it is highly variable due to the influence of, for example, noise produced by wind, wildlife, rustling vegetation, tourists and those goddamn aircraft flying overhead. But a good candidate, […]

If you’ve spent a little time wondering about how the cosmos works (as you should) you have likely stumbled across one of the so-called “constants” of the universe. These are physical quantities which cannot be derived through theory, and must be gained through going out there and measuring them through experiment. Classic examples include the […]

A massive 40-year study in the US has concluded that adding fluoride to drinking water does not reduce people’s cognitive ability. In fact, kids who grew up with fluoridated tap water performed slightly better in mathematics and reading in later life compared to those who didn’t. Scientists at the University of Minnesota looked at data […]

Guatemala’s rainforests support a remarkable diversity of cat species, including jaguars, pumas, ocelots, and the lesser-known margays. It’s unusual to have so many medium to large predators in one ecosystem, let alone from one family, and now scientists have worked out how they manage. Two species follow Michelle Obama’s philosophy: “When they go low, we […]

Happy birthday, Hannah Shirley! This year marks 52 trips around the Sun for the world’s oldest living pygmy hippopotamus in managed care, and what better way to celebrate than with a bash based on everyone’s favorite hippo-themed game? The team at San Diego Humane Society’s Ramona Wildlife Center, where Hannah Shirley is resident, really went […]

Whether it’s a frosty December morning or a breezy summer day, Germans will embrace the ancient art of lüften, part health practice, part cultural quirk – and many experts would recommend you give it a try yourself. Lüften, meaning “to air” in German, simply involves opening windows and doors to replace stuffy, stale air with […]
