Over the centuries, we have learned to put information into increasingly durable and useful form, from stone tablets to paper to digital media. Beginning in the 1980s, researchers began theorizing about how to store the information inside a quantum computer, where it is subject to all sorts of atomic-scale errors. By the 1990s they had… Continue reading Qubits Can Be as Safe as Bits, Researchers Show

Remember IBM’s Watson, the AI Jeopardy! champion? A 2010 promotion proclaimed, “Watson understands natural language with all its ambiguity and complexity.” However, as we saw when Watson subsequently failed spectacularly in its quest to “revolutionize medicine with artificial intelligence,” a veneer of linguistic facility is not the same as actually comprehending human language. Natural language… Continue reading What Does It Mean for AI to Understand?

I grew up in a small village in a very rural part of England. It was a landscape capped with the huge skies of a low-lying coastal zone. Gently rolling fields, long hedgerows, and a lot of farms. Some of the people running those farms came from so many generations that they could point to… Continue reading A Wrinkle in Nature Could Lead to Alien Life – Issue 111: Spotlight

So Dwyer and his team turned to the Low Frequency Array (LOFAR), a network of thousands of small radio telescopes mostly in the Netherlands. LOFAR usually gazes at distant galaxies and exploding stars. But according to Dwyer, “it just so happens to work really well for measuring lightning, too.” When thunderstorms roll overhead, there’s little… Continue reading Detailed Footage Finally Reveals What Triggers Lightning

It doesn’t feel right to see a toddler walking down the street by themselves. Toddlers don’t just go rogue, and if they do they are quickly chased down by a parent or grandparent or teacher and brought back where they belong. Most planets are like toddlers: They follow a well-behaved orbit around a star. It… Continue reading We Discovered a Rogues’ Gallery of Monster-Sized Gas Giants – Facts So Romantic

The recent election of Glenn Youngkin as the next governor of Virginia based on his anti–critical race theory platform is the latest episode in a longstanding conservative disinformation campaign of falsehoods, half-truths and exaggerations designed to create, mobilize and exploit anxiety around white status to secure political power. The problem is, these lies work, and… Continue reading The Anti–Critical Race Theory Movement Will Profoundly Affect Public Education

“Brain fog” is not a formal medical descriptor. But it aptly describes an inability to think clearly that can turn up in multiple sclerosis, cancer or chronic fatigue. Recently, the condition has grabbed headlines because of reports that it afflicts those recovering from COVID-19. COVID’s brain-related symptoms go beyond mere mental fuzziness. They range across… Continue reading How COVID Might Sow Chaos in the Brain
