16 Best Prime Day Fitness Tracker Deals and Smart Ring Sales (2025)

In the northern hemisphere, it's hard to not spend the winter in a state of slumbering sloth, just waiting for sunshine and good times to start again. Conveniently, Prime Day fitness tracker deals (all four days of them) drop right in the middle of summer, which makes this a great time to pick up the smartwatch or smart ring that you just didn't have the cash for at Christmas. This year, you have four whole days to shop the Amazon deals, but if you don't want to take that much time, I've highli

How ‘Star Wars’ Inspired a Late Change to James Gunn’s ‘Superman’

During post-production on Superman, writer-director James Gunn ran into a problem. “We found that people loved the movie but that they were confused about the world they were entering,” Gunn told io9 recently. And so, to fix that problem, late in the filmmaking process, he looked to another one of his favorite films for the fix. When Superman hits theaters this week, it opens with six sentences that set up not just the world of the DC Universe, but Superman’s origin and the film’s plot, all in

Mysterious Signals From Deep Space Expose Aftermath of Failed Cosmic Eruptions

Whenever we study space, we’re usually talking about long-lasting objects, like our own solar system or faraway galaxies that occasionally catch our attention when something extraordinary happens. But sometimes, the universe sends us quick, random bursts of energy that are usually too far away and too ephemeral for scientists to make any sense of—like fast X-ray transients (FXTs), whose elusive origins have long evaded astronomers. Recently, however, astrophysicists had a lucky strike: spotting

Exploring the Complexity of Distributed Consensus Algorithms in Blockchain

Consensus in blockchain isn’t just a technical problem—it’s an intellectual minefield. You’ve got decentralized nodes spread across the globe, each operating under different assumptions, with varying latencies, incentives, and potential motivations, and yet they’re all expected to come to the same conclusion about the state of a distributed ledger. No central authority, no fallback mechanisms, no easy resets. Just code, cryptography, and coordination dancing on the edge of chaos. It’s beautiful

5 reasons I’d buy the Galaxy Z Flip 7 over the Fold 7

Samsung’s new foldables may look like minor upgrades on the surface, but give them a closer look and the changes add up — enough to finally catch up with what Oppo and OnePlus have already been doing design-wise. Thankfully, Samsung’s finally in the same league again. And of the two foldables they’ve launched, I’m leaning strongly toward the Samsung Galaxy Z Flip 7. To be honest, I haven’t been a fan of the Galaxy Z Flip lineup so far — it always felt like it was trying too hard to milk nostalg

Inside OpenAI’s empire: A conversation with Karen Hao

And the third feature is that the empires monopolize knowledge production. So, in the last 10 years, we’ve seen the AI industry monopolize more and more of the AI researchers in the world. So AI researchers are no longer contributing to open science, working in universities or independent institutions, and the effect on the research is what you would imagine would happen if most of the climate scientists in the world were being bankrolled by oil and gas companies.

Why I don't ride the AI Hype Train

Ever since ChatGPT came out, the tech world has jumped on a new hype train—just like it did before with crypto, NFTs, and the metaverse. This time, I think the hype spread even faster because it was so easy to try—just open a website and start typing. ChatGPT quickly became one of the fastest-growing products ever, reaching 100 million users in 2 months. Like past trends, it also brought a lot of debate and strong opinions. I’ve used ChatGPT and other large language models (LLMs), and I’ve even

The Sounds of a Dying Glacier Might Make You Cry

From trippy mushroom synths to the stressed-out "pops" of thirsty plants, recording the music of nature has long resulted in soundscapes both fascinating and moving. A new recording of a melting glacier in the Swiss Alps, however, goes over the line right into devastation.

I couldn’t find the right tool, so I started building. I had no idea that side project would one day help over 100,000 households plan for their financial future
