Scientists have engineered what they say are the first self-replicating ‘robots’ ever made from living cells. At first, these freaky-looking ‘xenobots’ might seem notable for their superficial resemblance to Pac-Man, but their likeness to the video game character is probably the least strange thing about them.   These unusual robotic creatures are a spin-off of

Outbreaks of invasive moth caterpillars, Lymantria dispar dispar, and forest tent caterpillar moths, Malacasoma disstria, occur at least every five years in temperate forests. The insects munch through so many leaves that our research has found the resulting decrease in leaf-fall and increase in caterpillar poop hugely alter the way nutrients, particularly carbon and nitrogen,

Muons are everywhere. Unbeknownst to you, several hundred strike your head every second. These subatomic particles – created when cosmic rays enter the Earth’s atmosphere – are harmless and quickly decay into clusters of lighter particles.   The particles penetrate objects like X-rays do, which make them useful to scientists, who used muons to uncover

Smartphone technology has improved rapidly in recent years, giving us more battery life, better performance, and improved photo-taking capabilities – but they still come with screens that have a tendency to crack after being knocked or dropped.   Scientists have made encouraging progress in developing lead halide perovskite (LHP) screens that offer top-quality brightness and

The idea of artificial intelligence overthrowing humankind has been talked about for many decades, and in January 2021, scientists delivered their verdict on whether we’d be able to control a high-level computer super-intelligence. The answer? Almost definitely not.   The catch is that controlling a super-intelligence far beyond human comprehension would require a simulation of

The United Nations Climate Change Conference of the Parties (COP26) begins on Sunday 31 October in Glasgow, and the outcome may determine whether the world moves closer to a net-zero carbon economy by 2050.    The climate conference will bring together delegates from around the world to discuss their plans for reducing emissions and limiting climate

A talking CGI dinosaur just gave an impassioned speech about climate change to world leaders in a new UN video. Will they take it seriously? The dinosaur, named Frankie according to its Twitter page, bears a strong resemblance to the velociraptors from the film Jurassic World and is voiced by multiple celebrities in different languages, including film star and musician Jack

Almost 20 years after researchers first predicted electron quadruplets, evidence of their existence has been shown to occur in experimental setups, representing a brand new state of matter that opens up a whole new field of possibilities in physics.   Technically what we’re talking about here is fermionic quadrupling, referring to the type of particles

If you’re wondering just how much scientific consensus there is that humans have caused the climate of our planet to change, we can now put a number on it: 99.9 percent. That doesn’t leave much room for doubt. To get to that figure, researchers looked in detail at a total of 3,000 peer-reviewed studies randomly

The Arctic may no longer be the refuge it once was for migrating animals. Scientists now fear that climate change and environmental degradation have turned the yearly journey of numerous species, including birds, butterflies and ungulates, into an ecological trap.   Upon reaching their destination, many animals are likely starving, being hunted or dying of

The patterns of activity produced by our brains are unique. They’re so unique that we can use brain connectivity maps to identify individuals just as reliably as fingerprints. “An individual’s functional brain connectivity profile is both unique and reliable, similar to a fingerprint, and it is possible, with near-perfect accuracy in many cases, to identify
