NASA Mission to Map Sun’s Protective Bubble Could Help Better Predict Dangerous Space Weather

The Sun is an energetic star, constantly radiating energy and pumping streams of charged particles out into space. And while this solar wind can be dangerous in itself, without it, Earth and all the other members of our planetary system would be at constant risk of threats from outer space. Our host star creates a protective bubble called the heliosphere that extends far beyond the orbit of Neptune, shielding the planets from the interstellar medium. Yet though we may owe our existence to this b

AI-Enhanced Version of ‘The Wizard of Oz’ at the Sphere Could Pull in $1 Billion

The biggest blockbuster of the summer came out 86 years ago. While some people balk at the idea of paying $12 to catch a film that’ll be on streaming platforms a month later, apparently thousands of folks are flocking to the Sphere in Las Vegas and dropping about $200 a ticket to watch The Wizard of Oz, according to a report from Bloomberg. The film is reportedly grossing about $2 million per day from its showtimes on just one (very large) screen. Citing information from Wolfe Research, Bloombe

AUKEY’s new modular wireless charger is an absolute game changer

The world's first modular true wireless charger, AUKEY MagFusion Ark TL;DR The AUKEY MagFusion Ark is a modular wireless charging system with a Qi2.2 multi-pad base and detachable spheres. Each sphere has a 6,700mAh battery, a Qi2.2 charging pad, and a bi-directional 30W USB-C port, making it a portable power bank. The official launch and pricing are expected in Q1 2026. Multiple base plate and sphere configurations are planned. If you thought wireless chargers were boring, here’s a new one

This Unlikely Chemical Could Be a Powerful Weapon Against Climate Change

Year after year, humans pump more carbon dioxide (CO2) into the atmosphere than nature can remove, fueling global warming. As the need to mitigate climate change becomes increasingly urgent, scientists are developing ways to actively remove CO2 from the atmosphere in addition to cutting emissions. One of the biggest hurdles to scaling current carbon capture technologies is the vast amount of energy they consume, but what if there was an alternative that uses an abundant, cheap power source? A t

‘The Wizard of Oz’ at the Sphere Has a Shocking 2-Second Cameo: David Zaslav

The Sphere’s version of The Wizard of Oz has already drawn controversy over its use of AI. Now we know another unsettling element has been introduced into the Hollywood classic: a likeness of Warner Bros. Discovery CEO and president David Zaslav. No, really: the exec, along with the Sphere’s executive chairman and CEO, James Dolan, will be superimposed on the faces of uncredited background characters in what are apparently blink-and-you’ll-miss-them appearances. The stunt is to celebrate the mo

How Science Fiction Became the Key to This Year’s Most Buzzed About Concert

2001: A Space Odyssey. Star Wars. Star Trek. Tron. Blade Runner. Akira. The Fifth Element. Interstellar. Superman. Flash Gordon. The Matrix. That sounds like a list of the greatest sci-fi films of all time, but actually, it’s a list of the films mentioned during a discussion about the inspirations behind the Backstreet Boys’ popular new residency at the Sphere in Las Vegas, Nevada. This past July, one of the biggest boy bands of all time celebrated 20 years of their iconic album, Millennium, at

The Relativity of Wrong (1988)

The Relativity of Wrong by Isaac Asimov I received a letter from a reader the other day. It was handwritten in crabbed penmanship so that it was very difficult to read. Nevertheless, I tried to make it out just in case it might prove to be important. In the first sentence, he told me he was majoring in English Literature, but felt he needed to teach me science. (I sighed a bit, for I knew very few English Lit majors who are equipped to teach me science, but I am very aware of the vast state of

The Weight of a Cell

Ella Watkins-Dulaney Microbes are so small that tens of thousands could fit in the space of the period at the end of this sentence. And yet, for two of the most widely studied kinds — S. cerevisiae and E. coli — we know their weight with remarkable precision: A single yeast cell weighs about 100 picograms and a single E. coli bacterium weighs about one picogram, or 60 million times less than a grain of sand. At first blush, measuring the weight of a single cell seems an impossible task. How ca

Misunderstood “photophoresis” effect could loft metal sheets to exosphere

Most people would recognize the device in the image above, although they probably wouldn't know it by its formal name: the Crookes radiometer. As its name implies, placing the radiometer in light produces a measurable change: the blades start spinning. Unfortunately, many people misunderstand the physics of its operation (which we'll return to shortly). The actual forces that drive the blades to spin, called photophoresis, can act on a variety of structures as long as they're placed in a suffic

High costs and thin margins threatening AI coding startups

In February, AI coding startup Windsurf was in talks to raise a big new round at a $2.85 billion valuation led by Kleiner Perkins, at double the valuation it hit six months earlier, sources told TechCrunch at the time. That deal didn’t happen, according to a source familiar with the matter. Instead, news broke in April that the startup planned to sell itself to OpenAI for roughly the same valuation: $3 billion. While that deal famously fell apart, one bigger question remains: If the startup was

‘The Wizard of Oz’ blown up by AI for giant Sphere screen

In Brief The massive Las Vegas venue known as Sphere will be screening its first classic movie, “The Wizard of Oz,” starting on August 28. And as detailed in a segment on CBS Sunday Morning, this isn’t just a matter of taking the existing movie and projecting it on Sphere’s 160,000-square-foot, wraparound LED screen. Instead, Sphere Entertainment CEO James Dolan said a 2,000-person team is creating a new experience. That includes using AI to both increase the resolution of the existing film an

Cursor’s New Bugbot Is Designed to Save Vibe Coders From Themselves

But the competitive landscape for AI-assisted coding platforms is crowded. Startups Windsurf, Replit, and Poolside also sell AI code-generation tools to developers. Cline is a popular open-source alternative. GitHub’s Copilot, which was developed in collaboration with OpenAI, is described as a “pair programmer” that auto-completes code and offers debugging assistance. Most of these code editors are relying on a combination of AI models built by major tech companies, including OpenAI, Google, an

Was This the Geekiest Concert of All Time?

When the hamburger-shaped spaceship with the word “Millennium” on the back lowered down above me, I figured I was in for something special. What I didn’t expect was that, for the next two hours, the “Millennium…” let’s call it “Falcon,” would fly through an asteroid field before docking on a planet with light cycles and noir landscapes, as lines of code dropped down like rain and huge cylindrical gates of stars swirled around. But that’s what happened, and, I must say, it was phenomenal. Last w

The most otherworldly, mysterious forms of lightning on Earth

Our atmosphere is like one big electrical circuit: Thunderstorms are the batteries that charge it up, and lightning is the current flowing through it. On the ground we see evidence of this circuit when lightning cracks and strikes the ground, or when it lights up deep inside a thundercloud, but high above the clouds lies a secret electrical zoo full of sprites, elves, and jets. These fantastical terms refer to light displays called transient luminous events or TLEs that occur in Earth’s upper a

New sphere-packing record stems from an unexpected source

The advantage of Rogers’ method was that you didn’t have to start with a particularly efficient lattice to get an efficient sphere packing. You just had to choose the right ellipsoid. But this introduced a new complication. Unlike a sphere, which is completely defined by a single number — its radius — an ellipsoid is defined by several axes of different lengths. The higher the dimension, the greater the number of directions you can stretch your ellipsoid in, and the more options you have for wha

‘The Wizard of Oz’ at the Sphere Tests the Ways AI Can Preserve Classic Cinema

The Wizard of Oz is landing on the Vegas strip at the Sphere this summer, and it’s not without some controversy. The Warner Bros. classic Technicolor feature starring Judy Garland is being presented in a special limited engagement at the massive spherical stadium venue in Las Vegas, presumably in between music artist residencies. The state-of-the-art immersive entertainment center made its debut as a must-visit attraction with rock band U2. Now in a new venture, the Sphere collaborates with Wa

What Problems to Solve (1966)

What Problems to Solve - By Richard Feynman A former student, who was also once a student of Tomonaga’s, wrote to extend his congratulations. Feynman responded, asking Mr. Mano what he was now doing. The response: “studying the Coherence theory with some applications to the propagation of electromagnetic waves through turbulent atmosphere… a humble and down-to-earth type of problem.”

NASA's Voyager Found a 30k-50k Kelvin "Wall" at the Edge of Solar System

In 1977, NASA launched the Voyager probes to study the Solar System's edge, and the interstellar medium between the stars. One by one, they both hit the "wall of fire" at the boundaries of our home system, measuring temperatures of 30,000-50,000 kelvin (54,000-90,000 degrees Fahrenheit) on their passage through it. There are a few ways you could define the edge of the Solar System – for instance, where the planets end, or at the Oort cloud, the boundary of the Sun's gravitational influence wher

Anysphere launches a $200-a-month Cursor AI coding subscription

Anysphere launched a new $200-a-month subscription plan for its popular AI coding tool, Cursor, the company announced in a blog post on Monday. The new plan, Ultra, offers users 20x more usage on AI models from OpenAI, Anthropic, Google DeepMind, and xAI compared to the company’s $20-a-month subscription plan, Pro. Anysphere also says Cursor users on the Ultra plan will get priority access to new features. Anysphere CEO Michael Truell said in a blog that the Ultra plan was made possible throug

Scientists Reveal Easy Three-Step Plan to Terraform Mars

Terraforming, the act of radically transforming a planet's climate and environment to make it suitable for human habitation, currently belongs to the realm of science-fiction. But it's possible, at least in theory, and the idea of terraforming our nearest candidate planet for off-world colonization, Mars, has captivated us for generations. But how would we even begin to pull off such a monumental feat of engineering? You can basically boil it down to three simple steps, argue the authors of a r

Astronomers create first 3D map of a hellish alien planet's atmosphere

The big picture: Nearly 6,000 exoplanets have now been confirmed in the vast expanse of the Milky Way galaxy. Some are believed to have the potential to harbor life, while others are so hostile that they make Venus seem mild by comparison. One such planet is the ultra-hot Jupiter known as WASP-121b, nicknamed Tylos – a world so extreme it defies expectations. Located around 900 light-years away in the Puppis constellation, Tylos orbits its parent star at an absurdly close distance, completing a
