In George R.R. Martin’s fantastical land of Westeros in Game of Thrones and House of the Dragon, the spectacle of dragons breathing fire captivates his audience through a blend of myth and fantasy. For me at least, there’s also scientific curiosity. The images of dragons unleashing torrents of flames on the new series of House … Read more
The remarkable aurora in early May this year demonstrated the power that solar storms can emit as radiation, but occasionally the sun does something far more destructive. Known as “solar particle events”, these blasts of protons directly from the surface of the sun can shoot out like a searchlight into space. Records show that around … Read more
“Warp drives” used by super-advanced alien civilizations may create specific space-time ripples in their wake that we can spot from Earth, a new paper argues. However, the jury is still out on whether the faster-than-light technology is even possible to create in the first place. A warp drive is a hypothetical device that enables an … Read more
If you look up on a clear night, the brightest and largest object in the sky will probably be the moon. And unless you have a decent telescope, it is the only natural satellite you can see with your own eyes. As a result, most people have a warped perception of what a moon is … Read more
The Antikythera mechanism — an ancient shoebox-sized device that was used to track the motions of the sun, moon and planets — followed the Greek lunar calendar, not the solar one used by the Egyptians, as was previously thought, new research reveals. The Antikythera mechanism, found by sponge divers off the Greek island of Antikythera … Read more
Some memories last a lifetime — and now, scientists have revealed a type of molecular “glue” that helps those memories stick around. Memories form when collections of neurons in a region of the brain called the hippocampus activate in response to a particular experience. Each time you recall that experience, the same set of cells … Read more
The monster black hole at the center of our galaxy may be unleashing huge, gassy explosions — and now, astronomers think they’ve pinpointed the exact spot where that superheated gas is spilling into the Milky Way. Acting like a gargantuan exhaust vent, the newly discovered feature is a bright region of X-ray energy that’s nearly … Read more
Researchers have synthesized highly durable solar cells made from perovskite — a common crystal structure (in its natural form a calcium titanium oxide mineral) — in a breakthrough that could revolutionize the solar industry. Solar power is the fastest-growing energy technology and plays a key role in cutting greenhouse gas emissions. Solar power converts sunlight … Read more
With the release of artificial intelligence (AI) video generation products like Sora and Luma, we’re on the verge of a flood of AI-generated video content, and policymakers, public figures and software engineers are already warning about a deluge of deepfakes. Now it seems that AI itself might be our best defense against AI fakery after … Read more
Humans have shared stories about giants for thousands of years, from the cyclopes of Greek mythology to the biblical Goliath. But are these just tall tales, or have giant humans really walked this Earth? If you consider a nearly 9-foot-tall human a giant, then yes. Robert Wadlow, the tallest person on record, grew to 8 … Read more
