Medical and technological advances have allowed more of us to survive and to live longer, healthier lives. Does this make evolution irrelevant?  In the most basic sense, evolution refers to the process of genetic change in a population over time. It occurs because gene variants are more likely to survive and prosper if they offer […]

Mosquitos get a bad rep – and for good reason. Not only can these flying insects leave a nasty bite, they are responsible for transmitting the parasite that causes malaria. However, if new research is anything to go by, mosquitoes may also provide a creative solution to the disease. By infecting mosquitoes with a genetically […]

The more we learn about planets inside and outside our Solar System, the more difficult the question “Well, where the hell are aliens then?” seems to become. As well as finding a slew of planets in the habitable zones around their stars and locating new classes of exoplanets that may be good candidates for life, […]

In a world that seems to be pretty much designed to make us feel stressed and out of balance, our lord and master the social media algorithm loves to dish us up some apparently simple solutions. One of the most recent? Adaptogens. If your “For You” page is yet to explain what on Earth they […]

This week, fat cell “memory” could help explain why weight loss can be difficult to maintain, researchers might have figured out what made the Earth’s inner core go from molten to “frozen”, and first-of-its-kind footage zooms in on the life cycle of a giant virus. Finally, meet the shark-hunting dog that spent nearly a year […]

Atmospheric rivers have been gaining a lot of media traction lately. But while atmospheric rivers have played an integral role in the water cycle long before the birth of the dinosaurs, the term was first described surprisingly recently – in 1994. It refers to the long, narrow columns of water vapor that flow through the […]

While AI may be more commonly used for stealing art and hallucinating bullshit – that’s a technical term, by the way – the last couple of years have also seen what seem to be some genuinely extraordinary feats from the nascent technology. And that’s particularly true in the field of math: where computers were once […]

Imagine walking down a dark corridor, filled with looming shadows and jump scares at every corner. Your heart is rapidly beating in your chest, and you feel twitchy and ready to flee at a moment’s notice. Then suddenly a person dripping in “blood” rushes towards you carrying a loud chainsaw. You are in a haunted […]

Many people scoff at the sheer speed with which Snow White and her prince realized they were made for each other, or at The Little Mermaid‘s Ariel for tripping over her as-yet-imaginary feet to sign a dodgy contract in pursuit of a man she’d spent about eight seconds with. But if you think Jack and […]

Some animals have a “third eye”, and some spiders have as many as eight, but what about bees? A quick glance might lead you to answer “two”, and two pretty massive ones at that, but first impressions can be deceiving. How many eyes do bees have? Bees actually have five eyes: two compound eyes and […]

There’s lots of water in Antarctica, but most of it is frozen. You’d be forgiven, then, for thinking that rivers aren’t really a thing on the continent – however, you’d be mistaken. Antarctica is home to a number of waterways (at least for a few months a year) – the longest of which, called the […]

Located in one of the most remote corners of the Central Pacific is a small, uninhabited coral reef island known as Palmyra Atoll. Composed of 50 islets measuring no more than 2 meters (7 feet) in elevation, the U-shaped Palmyra Atoll is surrounded by 6,475 hectares (16,000 acres) of shallow and submerged barrier reefs.  One […]

On the jagged coast of Scotland lies an island that has stood deserted for decades, haunted by its legacy as a biological warfare testing ground during World War II. Gruinard Island is around 2 kilometers (1.25 miles) long and a short boat ride from the shore of Ross-shire in the Inner Hebrides of western Scotland. […]

Art critics of the world, look out – a pigeon might just be coming for your job. Well, if you’re in the business of deciding if a child’s artwork is good or bad at least, because that’s exactly what one scientist trained a bunch of pigeons to do. Watanabe Shigeru, a Professor Emeritus in psychology […]

Hundreds of scientists have gathered for an “emergency summit” in Australia to discuss the imperiled future of Antarctica. Concluding their findings in a statement published today, the polar researchers have a stark message: urgent action is needed to prevent the melting of Antarctica and catastrophic sea level rises around the world. “Nowhere on Earth is […]

A zircon crystal blasted off the face of Mars before landing on Earth as part of one of the most unusual meteorites ever found has revealed the oldest evidence of water on Mars. Moreover, it has shown that this water sometimes combined with sources of heat, presumably from volcanic activity, similar to those some think […]

Eat lots of fruits and vegetables, take regular exercise, and don’t smoke – probably the three most common health messages we all hear. The fact that smoking tobacco is a major risk factor for lung cancer – as well as numerous other diseases – is so well accepted now that it’s hard to imagine a […]

Not to sound superstitious or anything, but yet another oarfish has washed up in California. In early November 2024, Scripps Oceanography PhD candidate Alison Laferriere came across a dead oarfish, measuring roughly 2.7 to 3 meters (9 to 10 feet) in length, that had washed up on Grandview Beach in Encinitas.  The discovery follows at […]

This week on Break It Down, astronomers have taken the first-ever close-up photo of a star outside of the Milky Way, putting weight back on after losing it could be down to your fat cells’ “memories”, the mystery surrounding the Earth’s inner core “freezing”, footage shows a “giant” virus infecting a cell for the first […]

The oldest firearm ever discovered in the continental US has been found at the site of a massacre that occurred in Arizona in 1541. Brought to America by the Spanish conquistador Francisco Vázquez de Coronado, the bronze cannon was supposed to protect the residents of the first European settlement in the American Southwest, most of […]
