5,500 Superconducting Wires Survive Intense Testing for World’s Largest Fusion Reactor

Stakeholders around the world are vying to realize nuclear fusion—a fossil fuel alternative that promises maximum energy generation with minimal environmental risk. Behind the efforts to build the world’s largest fusion reactor is an equally gigantic global collaboration: ITER, which has just announced a major advance in its quest to prove fusion’s viability. In a paper published September 11 in Superconductor Science and Technology, the ITER Collaboration reported completing a key test to vali

New to Linux? 5 desktop environments I recommend you try first - and why

Jack Wallen / Elyse Betters Picaro / ZDNET Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways Not all Linux desktop environments are created equal. Some desktops are better suited for skilled Linux users. There are some desktops that make new users feel right at home. One aspect of Linux that has always been a strength is choice. As a user, you have the choice of making the open-source OS exactly what you want it to be. There are options for just about everything,

Sparky Linux is a great option, even for new Linux users. Get more in-depth ZDNET tech coverage: Add us as a preferred Google source on Chrome and Chromium browsers. Sparky Linux is well-known as a very good lightweight Linux distribution. Typically, Sparky defaults to the LXQt desktop, but offers versions with MATE, Xfce, and KDE

SOSV bets plasma will change everything from semiconductors to spacecraft

Sometimes a tool — like a hammer — comes along and everything starts looking like a nail. But other times, new tools end up being more than a simple blunt-force object. The investors at SOSV are betting that plasma will become a nuanced implement capable of everything from enabling fusion power to changing the way semiconductors are made. It sees so much potential that it plans on investing in more than 25 plasma-related startups over the next five years. It is also opening a new Hax lab space

NixOS on a Tuxedo InfinityBook Pro 14 Gen9 AMD Laptop

I link to TUXEDO a lot in this blog post. These links are not affiliate links, and this post is not sponsored (duh). TUXEDO Computers is a laptop manufacturer based in Augsburg, Germany, who are special to Linux users because they’re one of the few manufacturers developing specifically for Linux. They ship with their own TUXEDO OS, which comes with KDE Plasma by default. For my new job, I actually wanted a Framework laptop with an AMD chip, but they were temporarily out of stock so I opted for

SpaceX launches a pair of NASA satellites to probe the origins of space weather

Two NASA satellites rocketed into orbit from California aboard a SpaceX Falcon 9 rocket Wednesday, commencing a $170 million mission to study a phenomenon of space physics that has eluded researchers since the dawn of the Space Age. The twin spacecraft are part of the NASA-funded TRACERS mission, which will spend at least a year measuring plasma conditions in narrow regions of Earth's magnetic field known as polar cusps. As the name suggests, these regions are located over the poles. They play

New records on Wendelstein 7-X

Also called the Lawson Criteria, fusion triple product defines the threshold that must be exceeded for a plasma to produce more fusion power than the heating power injected. It marks the point where the energy balance across the plasma becomes positive, and the fusion reaction can sustain itself without (or with greatly reduced) external heating. The triple product is derived from three factors—ion temperature (T), density (n) and energy confinement time (τ). In any future fusion power plant, a

Astronomers Detect Entirely New Type of Plasma Wave Above Jupiter’s North Pole

Since entering Jupiter’s orbit in 2016, NASA’s Juno spacecraft has been hard at work unveiling the many mysteries of our solar system’s largest planet. And its latest discovery may be one of the most intriguing yet: an entirely new type of plasma wave near Jupiter’s poles. In a paper published Wednesday in Physical Review Letters, astronomers describe an unusual pattern of plasma waves in Jupiter’s magnetosphere—a magnetic “bubble” shielding the planet from external radiation. Jupiter’s excepti

Colossal Eruption Carves ‘Canyon of Fire’ Onto the Sun’s Surface

On July 15, a solar filament erupted from the Sun’s upper left side, ejecting a powerful blast of plasma and magnetic fields into space. The resulting explosion was so massive that it seared a deep, fiery scar of hot plasma and debris onto the star’s visible surface. While filament eruptions aren’t uncommon, astronomers had already been watching an unusually large filament—cold, dense ribbons of gas suspended above the Sun’s surface—that they spotted days before the explosion. When the filament

YPlasma zaps the air to cool chips for data centers

If you didn’t know any better, you might think it’s magic. David Garcia gave TechCrunch a demo video demonstration of a device developed by his company, YPlasma. A row of five candles sit in front of a harmonica-like device with wires hanging off it. Suddenly, the flames flicker and then snuff out. Inside the device, two strips of copper coursing with electrical current are generating plasmas, or clouds of charged particles, that induce airflow through the cavity and out over the candles. It’

This Debian-based Linux distro is an overlooked and user-friendly gem

Jack Wallen/ZDNET I spend a lot of time looking for Linux distributions that fit in certain niches, and one of the most important niches is those open-source operating systems that can serve the general public. When looking for such distributions, I tend to consider those based on Ubuntu first, which one might think is limiting, but there are hundreds of distributions with that base. Every so often, however, I run into a Debian-based distribution that fits the bill. That makes perfect sense, g

4 ways the latest KDE Plasma release is better than ever - and how to try it yourself

Jack Wallen / Elyse Betters Picaro / ZDNET Ladies and gents of the Linux community, it is time to enjoy another point release of yet another desktop environment: KDE Plasma 6.4. A point release? I got you all excited about a point release? Hear me out. 1. HDR/EDR support One of the biggest additions to KDE Plasma 6.4 is support for Extended Dynamic Range and a new High Dynamic Range wizard. The new HDR Calibration wizard is found in System Settings > Display & Monitor and only appears if you'

Your jump from Windows 10 to Linux gets easier with KDE Plasma 6.4

Weiquan Lin/Getty For the last few years, my favorite Linux desktop interface has been Linux Mint Cinnamon. However, that adoration doesn't mean I can't appreciate other Linux desktops. For example, when the KDE Community recently released KDE Plasma 6.4, I decided to give it a try on my openSUSE Tumbleweed machine, a Dell XPS 8300 with a 3.4GHz Intel Core i7-2600 processor, 16GB DDR3 RAM, and a 1.5TB 7200 rpm hard drive from 2011. That machine can run Windows 10 (you can forget about Windows

Every fusion startup that has raised over $100M

Over the last several years, fusion power has gone from the butt of jokes — always a decade away! — to an increasingly tangible and tantalizing technology that has drawn investors off the sidelines. The technology may be challenging to master and expensive to build today, but fusion promises to harness the nuclear reaction that powers the sun to generate nearly limitless energy here on Earth. If startups are able to complete commercially viable fusion power plants, then they have the potential
