Local cuisine was on the menu at Cafe Neanderthal

Sixty thousand years ago, two groups of Neanderthals lived just a stone’s throw apart in what’s now northern Israel. But they had very different cultures when it came to food, according to a recent study. Archaeologist Anaëlle Jallon of Hebrew University of Jerusalem and her colleagues examined dozens of animal bones from both sites, looking for clues about Neanderthal meal prep. It turns out that something as mundane as the cut marks left by butchering an animal can reveal differences in ancien

Tuesday Telescope: Webb and Hubble team up to reveal spectacular star clusters

Welcome to the Tuesday Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’ll take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder. Open clusters of stars—which consist of dozens up to a few thousand stars—are an interesting tool for astronomers to study the Universe. T

Optimizing Tool Selection for LLM Workflows with Differentiable Programming

Modern agentic architectures rely heavily on chaining LLM calls. A typical pattern looks like: Use an LLM to decide which tool to invoke Call the tool (e.g. search, calculator, API) Use another LLM call to interpret the result and generate a final response This structure is easy to reason about, simple to prototype, and generalizes well. But it scales poorly. Each LLM call incurs latency, cost, and token overhead. More subtly, it compounds context: every step includes not only the original q

A rare look inside the durability lab where Apple tortures its products

Apple puts its products through a lot of tests during the development process, intended to ensure they have a long and reliable life even in challenging conditions. The company tests at least 10,000 iPhones prior to launch in an attempt to cover all the bases. It’s not often the iPhone maker lets outsiders into its labs, but Apple invited some of those attending WWDC 2025 to visit one to see for themselves the conditions it expects its gadgets to survive … To be clear, it’s not the first time

I want to leave tech: what do I do?

Let’s say you’re working in tech and you have a technical role: you’re a programmer, a graphic or UI/UX designer, a sysadmin, maybe even a product manager. Let’s say you want to leave, change career, and do something more meaningful with your skills. Your motivations may vary: you feel the tech industry produces nothing of value, or maybe you have the legitimate suspicion that what you build helps bomb innocent people somewhere. You might want to leave because of the individualistic culture tha

What James Gunn’s ‘Superman’ Tells Us About the Future of the DC Universe

It’s been years since James Gunn and Peter Safran first announced their plans for the future of the DC Universe. In that time, plans have changed slightly, and work is ongoing, but, with one exception, we have yet to see exactly how things are going to play out. That changes July 11 with the release of Superman. Not only is the film our first introduction to this brand-new, reimagined version of Superman, it’s our first look at what Gunn and Safran’s DC Universe looks like on the big screen. Sp

New Images Show Andromeda Galaxy as You’ve Never Seen It Before

Andromeda lies 2.5 million light-years away from the Milky Way, a spiral galaxy similar to our own that has allowed scientists to better understand our galactic home. A new composite image reveals our closest galactic neighbor in five different wavelengths of light, combined together to create a stunningly detailed view of Andromeda. Telescopes capture images in different wavelengths by observing a specific part of the electromagnetic spectrum, from low-frequency radio waves to extremely high-f

Planting flags in AI coding territory

Answering this often triggers more questions that shouldn't surprise anyone. Do you have some workable requirements? Have you created meaningful tests aligned with those? Can you understand and fix your code when those tests fail? Are you seeing opportunities to delete code in a way that enhances its value by reducing its liability? In all of these questions, code is ingrained with purpose, hampered by ambiguity, and therefore very much human, even when it lies forgotten in some machine wher

Apple's Workout Buddy Is Friendly, but What if It Could Adopt Other Personalities?

We all have different ways of motivating ourselves to exercise, so when Apple announced Workout Buddy for the Apple Watch at WWDC 2025, it made us think about what sorts of verbal encouragement would spur us to complete our workouts. We couldn't help but imagine the different types of future Workout Buddies -- and how they might help, cajole or even bargain with us to hit our fitness goals. Workout Buddy in WatchOS 26 will be available at the outset in eight workouts (such as running and cyclin

Apple will at long last let you customize snooze times on alarms in iOS 26

We've been covering all the news Apple announced at WWDC 2025, but possibly the most exciting element coming to iOS 26 wasn't discussed on stage. The next update to the operating system will let people set custom snooze times. MacRumors reported that iOS 26 will offer anywhere from one to 15 minute snoozes that users can select when setting the alarm. For years, Apple has kept the snooze timing locked at nine minutes. If you wanted to doze at a different interval, you'd need to set separate ala

Google Home now lets you control your smart devices, your way

TL;DR Google Home now lets you set up different Favorites for each device. That means you can pin the front door as a favorite on your smartwatch, while the lounge light is pinned on Google TV. This should be useful if you tend to control different smart home gadgets via specific devices. Google has just announced the stable release of Android 16, while also revealing a few features for ecosystem users. It turns out there’s a notable addition to the Google Home app as well. The search giant

Study: Cuttlefish adapt camouflage displays when hunting prey

Crafty cuttlefish employ several different camouflaging displays while hunting their prey, according to a new paper published in the journal Ecology, including mimicking benign ocean objects like a leaf or coral, or flashing dark stripes down their bodies. And individual cuttlefish seem to choose different preferred hunting displays for different environments. It's well-known that cuttlefish and several other cephalopods can rapidly shift the colors in their skin thanks to that skin's unique st
