Quantum entanglement comes in a new form, one that could be used to make quantum information technology smaller, once it becomes practical outside the laboratory. The work relies on the fact that when photons are restricted to spaces smaller than their wavelengths two of their properties merge into one. Quantum entanglement links the destinies of […]

Astronomers think there could be as many as 100 million black holes in our galaxy, most with a similar mass to our Sun, but they are not that easy to find. With no light able to escape them, black holes are usually detected when they are eating, since their feeding frenzies emit a lot of […]

As the only surviving members of the Hominini tribe, us Homo sapiens have the important responsibility of piecing together our family tree, documenting all those extinct human species upon whose hairy shoulders we stand. Yet the more fossils we discover, the messier the picture seems to get, and the harder it becomes to figure out […]

This week, we visited the How To Fix Our Broken Planet exhibit at the Natural History Museum, London, to discuss how whale earwax is spilling the ocean’s secrets. RFK Jr has claimed that we will “know” the cause of autism by September, a statement that science says is very unlikely, the world’s oldest analog computer […]

It would be incredibly useful if humans (just like sharks and elephants) could continuously grow new teeth throughout their lifetime, replacing those lost to disease, neglect, and bar fights. This is the fundamental idea that’s inspiring scientists to explore the prospect of lab-grown teeth.  In a new study, scientists at King’s College London and Imperial […]

When Mount St Helens erupted in 1980, the resulting lava, ash, and debris turned the landscape barren for miles around. It was clear the land would take a long time to recover from the eruption. But one team of scientists had an idea about how they could help speed up the process: sending a few […]

The global navigation satellite system, of which GPS is the most famous example, is a crucial aspect of modern life. From planes to cargo ships, to simply finding your way around a new city or just getting home, satellites help us navigate the world. The system is not foolproof, though, and it doesn’t work in […]

The Sun goes through an 11-year cycle of activity, going from the solar maximum, where it is covered in many sunspots and is more likely to have flares and coronal mass ejections, to the minimum, where there are no spots and those events are extremely rare. But this is not only the cycle our star […]

Times are tough at the moment and world news may feel like we are bouncing from one negative story to another, so here’s something to add some pep to our news consumption step. Anti-Personnel Landmines Detection Product Development (APOPO), a Belgian non-governmental organization, has just announced that HeroRAT Ronin has broken the Guinness World Record […]

It’s a truth often played for laughs that alcohol messes with your brain function. That’s why the cops make you do stuff like walk in a straight line and touch your nose when they suspect you’ve been drinking: those are some of the first things to deteriorate after a heavy night at the bar. But […]

In the cutthroat jungles of Madagascar, vast webs hang over the landscape’s bustling rivers, scooping up prey like industrial-strength bug-catching nets. They’re the handiwork of none other than Darwin’s bark spider. Despite the females being smaller than a human hand, this remarkable arachnid weaves webs that can stretch up to 25 meters (82 feet) across […]

Olo is described as a “new color” that scientists argue they’ve enabled people to see – one that doesn’t resemble anything in our everyday visual experience. It’s described as an intensely saturated greenish-blue, brought to life using a new technique that stimulates the eye’s photoreceptors in a non-conventional way. “We name this new color ‘olo’,” […]

Early next week, the Lyrid meteor shower will have its peak, and the Moon being less than half full will not ruin the spectacle too much. If you’re planning to watch, you won’t need any specialist equipment. In fact, telescopes or binoculars are often a hindrance to catching meteors.   The peak will be on […]

Pandemics, contentious political environments, economic distress, continued war, ecological degradation, climate change, wildfires – all these themes have featured in the 24-hour news cycle over the last few years, and it can be exhausting to constantly follow them all. However, consistently engaging with negative news is not just demoralizing. The frequent consumption of such information […]

We have been moderately lucky with comets in the last several months. We had Comet Tsuchinshan-ATLAS last October shining across the sky for weeks, visible to the naked eye, having survived a dangerous close encounter with the Sun. That chance now lies with C/2025 F2 (Swan), although it’s not expected to get as bright. The […]

Could aquatic mammals, such as whales, orcas, and bottlenose dolphins, ever evolve to live on land again? It seems the chances of this are actually vanishingly small, as the adaptations that allow them to thrive in the water are more or less irreversible, representing an evolutionary threshold beyond which there can be little chance of […]

What do Freddy Mercury, Nero’s mom, and an ancient Bulgarian vampire have in common? That’s right: they all have hyperdontia – aka “too many teeth”.  But while for these three toothy icons, their dental situation was variously a source of embarrassment, a lucky omen, and a genuine benefit to their goal of eating the local […]

In most European languages, the name of the holiday commemorating the resurrection of Jesus derives from the word “Pascha.” It’s called Pâques in French, Pasqua in Italian, Pasg in Welsh, Påske in Danish, Páskar in Icelandic, and Pasen in Dutch. Why, then, do we call it “Easter” in English? First things first, Pascha (or Πάσχα) […]

Whether it’s Adam and Eve being shunned from Eden, Prometheus chained upon the rock, or Odin sacrificing his own eye, humanity has long agreed: wisdom comes at a price.  Of course, for most of us, growing to an age where we might accept and understand the world a little better won’t bring the kinds of […]

Throughout the Iron Age, wealthy elites and royals swanned around the Mediterranean decked out in purple robes – although where and how these flamboyant garments acquired their aubergine hues has until now remained a mystery. Yet the authors of a new study report the discovery of an industrial-scale purple dye workshop near Haifa, Israel, which […]
