Bloom Filters by Example

Bloom Filters by Example A Bloom filter is a data structure designed to tell you, rapidly and memory-efficiently, whether an element is present in a set. The price paid for this efficiency is that a Bloom filter is a probabilistic data structure: it tells us that the element either definitely is not in the set or may be in the set. The base data structure of a Bloom filter is a Bit Vector. Here's a small one we'll use to demonstrate: Each empty cell in that table represents a bit, and the nu

Student Solves a Long-Standing Problem About the Limits of Addition

The original version of this story appeared in Quanta Magazine. The simplest ideas in mathematics can also be the most perplexing. Take addition. It’s a straightforward operation: One of the first mathematical truths we learn is that 1 plus 1 equals 2. But mathematicians still have many unanswered questions about the kinds of patterns that addition can give rise to. “This is one of the most basic things you can do,” said Benjamin Bedert, a graduate student at the University of Oxford. “Somehow

I Let AI Agents Plan My Vacation—and It Wasn't Terrible

The worst part of travel is the planning: the faff of finding and booking transport, accommodation, restaurant reservations—the list can feel endless. To help, the latest wave of AI agents, such as OpenAI’s Operator and Anthropic’s Computer Use claim they can take these dreary, cumbersome tasks from befuddled travelers and do it all for you. But exactly how good are they are digging out the good stuff? What better way to find out than deciding on a last-minute weekend away. I tasked Operator, w

James Webb Discovers First-Ever Exoplanet by Taking a Picture of It

BusyBeaver(6) Is Quite Large

For overdetermined reasons, I’ve lately found the world an increasingly terrifying and depressing place. It’s gotten harder and harder to concentrate on research, or even popular science writing. Every so often, though, something breaks through that wakes my inner child, reminds me of why I fell in love with research thirty years ago, and helps me forget about the triumphantly strutting factions working to destroy everything I value. Back in 2022, I reported an exciting advance in BusyBeaverolo

Facebook is asking to use Meta AI on photos in your camera roll you haven’t yet shared

Facebook is asking users for access to their phone’s camera roll to automatically suggest AI-edited versions of their photos — including ones that haven’t been uploaded to Facebook yet. The feature is being suggested to Facebook users when they’re creating a new Story on the social networking app. Here, a screen pops up and asks if the user will opt into “cloud processing” to allow creative suggestions. As the pop-up message explains, by clicking “Allow,” you’ll let Facebook generate new ideas

Authors call on publishers to limit their use of AI

In Brief An open letter from authors including Lauren Groff, Lev Grossman, R.F. Kuang, Dennis Lehane, and Geoffrey Maguire calls on book publishers to pledge to limit their use of AI tools, for example by committing to only hire human audiobook narrators. The letter argues that authors’ work has been “stolen” by AI companies: “Rather than paying writers a small percentage of the money our work makes for them, someone else will be paid for a technology built on our unpaid labor.” Among other c

Tech Workers Say They're Rapidly Being Replaced by AI

"She claimed it was outperforming us." As AI conquers every human-driven endeavor at a breathless pace, from bombing military targets to teaching kids, we gotta ask ourselves a scary question: what is it doing to the workplace right now, and in the future? Sure, we have Dario Amodei, CEO of hotshot AI company Anthropic, saying he foresees AI models erasing 50 percent of entry-level white collar positions throughout the entire job market, but that could be all marketing hype.

Scientists Intrigued by Comet With Jets Blasting From Its Interior

What can a comet tell us about the Universe? Vomit Comet Astronomers have detected a gigantic comet — possibly the largest ever discovered — and it's spewing gases from its nucleus as it shoots through our cosmic neighborhood. Comet C/2014 UN271 (Bernardinelli-Bernstein) is 85 miles in diameter, far bigger than the six-mile asteroid that ended the age of the dinosaurs, according to a new study in The Astrophysical Journal Letters. But thankfully, it's pretty far away — in the vicinity of Nept

Facebook test uses Meta AI to process photos you've yet to upload

In that notification, Meta wrote that in order to create ideas for users, it'll select media

This Prehistoric Trick Shows How Ice Age People Harvested Teeth for Jewelry

When piecing together the cultural practices of ancient humans, traditional archaeologists rely on clues from artifacts such as tools, bones, and pottery. Experimental archaeologists, however, go a step further—recreating past behaviors to experience how people once lived. That’s precisely what a team of researchers recently did to investigate how Stone Age communities in northeastern Europe extracted animal teeth to produce accessories.

Meta Won Its AI Fair Use Lawsuit, but Judge Says Authors Are Likely 'to Often Win' Going Forward

AI companies scored another victory in court this week. Meta on Wednesday won a motion for partial summary judgment in its favor in Kadrey v.
