Take a Trip to the Final Frontier With This Year’s Best Astronomy Photography

When a comet meets solar winds, its nuclear coma—a bright cloud of gas around its core—reacts vibrantly to our Sun’s solar maximum, leaving a trail of stellar gas and dust across the solar system. Miraculously, the sky above June Lake, California, cleared up for a full 13 minutes for photographer Dan Bartlett to image the comet clearly enough for his photograph, “Comet 12P/Pons-Brooks Taking a Final Bow.” With incredible technological advances, the continuous flow of space photos can sometimes

Physicists Made a Time Crystal We Can Actually See

Of all the eccentricities of the quantum realm, time crystals—atomic arrangements that repeat certain motions over time—might be some of the weirdest. But they certainly exist, and to provide more solid proof, physicists have finally created a time crystal we can actually see. In a recent Nature Materials paper, physicists at the University of Colorado Boulder presented a new time crystal design: a glass cell filled with liquid crystals—rod-shaped molecules stuck in strange limbo between solid

This is the Most Effective Type of Creatine You Should Be Taking to See Results, According to Registered Dietitians

If you look in the supplement aisle at your local pharmacy, you'll likely find different forms of creatine in gummies, powders, capsules and even drink mixes. That's because creatine is a popular fitness supplement for those who want to gain strength and power while improving performance. It's also naturally made in our bodies and assists our muscles with energy production when we work out. Though creatine can be found in smaller quantities in foods like salmon, chicken, beef and pork, many peo

Education report calling for ethical AI use contains over 15 fake sources

On Friday, CBC News reported that a major education reform document prepared for the Canadian province of Newfoundland and Labrador contains at least 15 fabricated citations that academics suspect were generated by an AI language model—despite the same report calling for "ethical" AI use in schools. "A Vision for the Future: Transforming and Modernizing Education," released August 28, serves as a 10-year roadmap for modernizing the province's public schools and post-secondary institutions. The

New FAA program will let eVTOL startups test some operations before full certification

The Federal Aviation Administration (FAA) has announced a new pilot program that will let electric vertical takeoff and landing (eVTOL) startups test some operations before they receive full regulatory certification. It’s a potentially big change for these companies, as they’ve spent the last few years performing limited test flights of their aircraft while working toward FAA approval. But the program has its limits. Companies will have to partner with state, local, tribal, or territorial gove

Joby and Archer join FAA's eVTOL pilot testing program

The Federal Aviation Administration said Friday it's launching a pilot program to speed up the rollout of air taxis. Archer Aviation and Joby Aviation , major players in the electric vertical takeoff and landing, or eVTOL, space, said they are participating in the program. Shares of each were higher on Friday. The program will establish at least five projects through public-private partnerships with state and local governments to promote safe usage of electric vertical takeoff and landing airc

A Beginner's Guide to Extending Emacs

With that prelude out of the way, let's begin. Inside of emacs you can call up a list of potential completions by using the keyboard shortcut M-. (that’s "hit the meta key along with period", where "meta" is the Alt key for me). This applies in a wide variety of scenarios, like when completing class names or variables. If we want to ask emacs to hand us a list of potential references, then the system we want to hook into is this completions system. (This is the only time I'll assume we know wh

New pathway engineered into plants lets them suck up more CO₂

Lots of people are excited about the idea of using plants to help us draw down some of the excess carbon dioxide we've been pumping into the atmosphere. It would be nice to think that we could reforest our way out of the mess we're creating, but recent studies have indicated there's simply not enough productive land for this to work out. One alternative might be to get plants to take up carbon dioxide more efficiently. Unfortunately, the enzyme that incorporates carbon dioxide into photosynthes

How to Make Legacy Databases AI-Ready

A significant roadblock organizations face when taking advantage of artificial intelligence (AI) and machine learning (ML) is a legacy database. ITP.net reports that nearly 90 percent of businesses are hindered by legacy technologies, and approximately 62 billion data and analytics work hours are lost annually due to their inefficiencies. Organizations frequently grapple with legacy system issues, including security risks, increased costs, poor data accessibility, and slow AI model training. To

Claude’s memory architecture is the opposite of ChatGPT’s

Claude Memory: A Different Philosophy How Claude memory works, how it differs from ChatGPT, and what these approaches reveal. Earlier this week, I dissected ChatGPT's memory system. Since then, I've been doing the same for Claude and realized something remarkable: these two leading AI assistants have built completely opposite memory systems. In this post, I'll start by breaking down exactly how Claude's memory works—what it stores and how it retrieves information. Then we'll get to the intere

We are entering a golden age of robotics startups — and not just because of AI

When Seth Winterroth left his job at GE Ventures to help launch Eclipse Ventures in 2015, robotics was on his mind. Or more specifically, the number of early-stage robotics startups that were struggling to launch due to lack of interest. “These are teams that had just finished their postdocs at Waterloo, or CMU, or MIT, and were starting robotics companies, and the refrain that I continually heard from the startups was, ‘hey, we’re having a really hard time raising institutional venture capital

Microsoft slips unscathed through EU competition probe after promising to unbundle Teams

Thanks to a pledge to unbundle its corporate messaging app Teams from its productivity suites, Microsoft has managed to slip unscathed through a major antitrust investigation by the European Commission that could have resulted in massive fines for the tech giant. The Commission on Friday okayed Microsoft’s concessions to address the EU’s competition concerns over the company including Teams along with the rest of its Office productivity suite for free, concluding a multi-year investigation that

We will, of course, put a live tracker online for his journey, and thanks to modern communications equipment, the paddler will be able to send information, pictures and even videos from the middle of the Atlantic. Preparations for this special challenge have been ongoing for many months. However, for a project like this to come together, a lot of things have to fit together perfectly.

A Modular Couch Is Worth It. Here’s Why

A sofa is one of the biggest investments you can make in home decor, and the last thing you want is to make the wrong choice. A good couch will be with you for a decade, and it should not only be comfortable and look great, it should also have the versatility to adapt to your needs in new spaces and seasons of your life. You should consider a modular sofa. That's the kind that comes in individual pieces you can pull apart, put back together, and rearrange to suit whatever you fancy. Usually, yo

AI 'friend' chatbots probed over child protection

AI 'friend' chatbots probed over child protection The seven companies - Alphabet, OpenAI, Character.ai, Snap, XAI, Meta and its subsidiary Instagram - have been approached for comment. The impacts of AI chatbots to children is a hot topic, with concerns that younger people are particularly vulnerable due to the AI being able to mimic human conversations and emotions, often presenting themselves as friends or companions. The Federal Trade Commission (FTC) is requesting information on how the c

How do AI models generate videos?

Sure, the clips you see in demo reels are cherry-picked to showcase a company’s models at the top of their game. But with the technology in the hands of more users than ever before—Sora and Veo 3 are available in the ChatGPT and Gemini apps for paying subscribers—even the most casual filmmaker can now knock out something remarkable. The downside is that creators are competing with AI slop, and social media feeds are filling up with faked news footage. Video generation also uses up a huge amount

The Morning After: HBO Max is going to get more expensive

As is often the case, the tech news tide is out after Apple’s iPhone 17 event. (Did we do a dedicated newsletter on all the announcements? Yes, yes we did.) Before the weekend, though, there’s still more to read about. But let’s start with the not-great tech news. David Zaslav, CEO of Warner Bros. Discovery, plans to make HBO more expensive and passwords a lot harder to share. These were part of his comments at a Goldman Sachs Communacopia + Technology Conference, which sounds awful. The main

How I use a smart outlet to save money on electricity bills every month

Smart Wi-Fi power strips are a great way to save on your power bill. But do they pay for themselves? Adrian Kingsley-Hughes/ZDNET Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways Leaving devices plugged and switched on can be wasteful. Monitoring usage and remote switching helps reduce bills. This Tapo smart power strip is a great option to monitor power consumption, and at $45, it pays for itself. I have three 3D printers that are on the go a lot of the time. I

Gene-edited pancreatic cells transplanted into a patient with type 1 diabetes

Crispr gene-editing technology has demonstrated its revolutionary potential in recent years: It has been used to treat rare diseases, to adapt crops to withstand the extremes of climate change, or even to change the color of a spider’s web. But the greatest hope is that this technology will help find a cure for a global disease, such as diabetes. A new study points in that direction. For the first time, researchers succeeded in implanting Crispr-edited pancreatic cells in a man with type 1 diab

Introduction to Nyquist and Lisp Programming

Dannenberg and was intended to be used as a complete programming language for audio synthesis and analysis, with support for MIDI, audio recording and playback, file I/O, object-oriented programming, profiling, debugging and more. Audacity uses a subset of Nyquist's functionality, allowing you to use Nyquist functi

Becoming the person who does the thing

It can be disorienting when our beliefs shift. The world we helped create no longer exists, and our role in it transforms too. It can be unsettling, naturally. But that's kind of the point. Looking back at times when I held certain beliefs—about how the world works, and what my role in this story is—it can feel less like a mod was installed and more like an entirely new operating system was swapped in. Up until my late twenties, I could count the number of times I had been to the gym on one h

The New York Times Mini Crossword Now Has a Paywall, but There Is a Way to Play

I'm a fan of the New York Times Mini Crossword -- a sporty, streamlined companion to the newspaper's legendary regular daily crossword. Typically, the Mini Crossword (we publish the answers daily) has roughly a dozen clues to work through -- six across-clues and six down-clues -- and you can complete it in less than a minute if all goes well. It makes me feel smart, unlike the big crossword, which sometimes makes me throw things. But in late August, some Mini Crossword players suddenly ran int

Apple Watch hypertension alerts feature receives FDA clearance
