In the last few months, Meta has seemingly taken its foot off the gas when it comes to developing next-generation VR hardware and experiences. The Beijing-based Chinese competitor, ByteDance, the creator of TikTok, is going the other way — and it appears focused on expanding its work beyond just gaming.

The Pico Project Swan, announced at Mobile World Congress in Barcelona this week, is a lot of head hardware. Coming “later this year,” according to ByteDance, it doesn’t sound cheap. An onboard micro OLED display will have 40 pixels per degree of resolution density, which should be in line with what the Apple Vision Pro and Samsung Galaxy XR offer. The headset will have similar capabilities to create mixed-reality overlays of graphics in real-world settings using passthrough cameras.

The headset is also powered by its own dual-chip custom processors that ByteDance claims are twice as powerful as Qualcomm’s Snapdragon XR2 Gen 2 chip that’s on Meta’s Quest 3 and 3S headsets, and in a stepped-up version on Samsung Galaxy XR. While that may still lag behind Apple’s M5 chip on the Vision Pro, it’s a lot for a mixed reality headset.

As for the price of Project Swan and what software it’ll run, that’s still a mystery. Pico headsets already run Android apps and can connect to Windows PCs, but the landscape of VR/AR is changing rapidly.

Apple and Samsung’s headsets feel like prototypes for future computers that still don’t have enough unique software yet. Meta’s emphasis on smaller AR glasses to come mirrors planned moves by Google and Samsung, and Apple could be following suit.

Meanwhile, Valve’s gaming-focused Steam Frame headset, coming later this year, shows another interesting wrinkle in the mix. Valve is running Steam on smaller ARM chips, which could mean Steam OS running on other XR hardware after that. Running more types of software on smaller chipsets is exactly what VR headsets needed more of in the first place.

I’m curious about Project Swan, though. At the least, it shows that other companies are keeping the ball rolling on high-end headsets, even if Meta currently seems not to be. 

A reported outage for Anthropic’s Claude AI lasted more than two hours on Monday morning. The company said it had resolved errors for Claude.AI, Claude Code and its Claude Opus 4.6 model shortly before 11 a.m. ET (8 a.m. PT).

The outage started just before 7 a.m. ET Monday. Anthropic’s status page showed continued errors more than two hours later.

Downdetector showed reported problems with Claude spiking around 6:45 a.m. ET, with nearly 2,000 reports. That number had dropped to 275 by 9:30 a.m. ET. (Disclosure: Downdetector and CNET are both owned by the same parent company, Ziff Davis.)

Nothing has officially teased the highly anticipated Phone 4a once again. After revealing the light pink variant last week, the full roster has now made a public appearance. But while we’re only getting tidbits from the brand, these pictures arrive just a day after a big leak revealed most of the important hardware details of the upcoming device.

Everything in the official teaser

Liquid nitrogen isn’t exactly an everyday material, but it’s acquired conveniently enough to be used in extreme overclocking experiments, classroom demonstrations, chemistry and physics experiments, and a number of other niche applications. Liquid oxygen, by contrast, is dangerous enough that it’s only really used in rocket engines. Nevertheless, [Electron Impressions] made some of his own, and beyond the obvious pyrotechnic experimentation, demonstrated its unusual magnetic properties. Check out the video, below.

The oxygen in this case was produced by electrolysis through a proton-exchange membrane, which vented the hydrogen into the atmosphere and routed the oxygen into a Dewar flask mounted at the cold end of a Stirling cryo-cooler. The cooler had enough power to produce about 30 to 40 milliliters of liquid oxygen per hour, enough to build up an appreciable amount in short order. As expected, the pale blue liquid caused burning paper to disappear in a violent flame, and a piece of paper soaked in it almost exploded when ignited.

More interestingly, a piece of oxygen-soaked paper could also be picked up with a strong enough magnet. This is due to molecular oxygen’s paramagnetism, which is too weak to be significant in a gas made of quickly-moving molecules, but becomes noticeable in a liquid. When some liquid oxygen was poured onto a strong magnet, it stuck to the edges of the magnet, whereas liquid nitrogen just splashed away. Even as the liquid oxygen evaporated, it was possible to faintly see some of the cold vapours sticking close to the magnet. [Electron Impressions] tried to create a kind of coil gun by wrapping a coil around a test tube containing liquid oxygen, but it didn’t really work. Any effect was imperceptible among the disturbances caused by boiling oxygen and the physical jolt of the power supply connecting.

It’s not a process we’ve seen before, but the boiling point of liquid nitrogen is lower than the boiling point of oxygen, so if you have a convenient source of liquid nitrogen, it’s simple enough to make liquid oxygen.

Every time Russia attacks Ukraine’s power infrastructure, Ukrainian engineers risk their lives in the scramble to get electricity flowing again. It’s a dangerous job at best, and a lethal one at worst. It also requires creativity. Time pressure and equipment shortages make it nearly impossible to rebuild things exactly as they were, so engineers must redesign on the fly.

These dangerous, stressful conditions have led to more engineers being hurt or killed. The rate of injuries among Ukrainian workers in electricity generation, transmission, and distribution jumped nearly 50 percent after Russia’s full-scale invasion began four years ago, according to data provided by Antonina Nagorna, who leads the Department of Epidemiology and Physiology of Work at the Kundiiev Institute of Occupational Health, in Kiev. By her count at least 48 people had died on the job through the end of 2025, either while repairing damage or during the bombardment itself.

Transmission mastermind Oleksiy Brecht joined that grim count in January. Brecht, who was director for network operations and development at the Ukrainian grid operator Ukrenergo, died while coordinating work at Ukraine’s most attacked electrical switchyard, Kyivska, west of the capital. He was 47 years old.

Brecht’s life and death are a window into the realities of thousands of Ukrainian engineers who face conditions beyond what most engineers could imagine. “The war completely transformed the professional life of a top-manager engineer,” says Mariia Tsaturian, an energy analyst and chief communication officer at the think tank Ukraine Facility Platform, who previously worked with Brecht at Ukrenergo. “As for junior staff, their world was turned upside down entirely. A substation engineer working under shelling is something no one had ever seen or experienced before,” she says.

How Russia Attacks Ukraine’s Grid

Over the course of the war, Russia has increasingly focused on destroying Ukraine’s energy infrastructure. It sends attack drones almost daily during the winter there, when heat and electricity is needed most to survive the bitter cold. Every 10 days or so it barrages Ukraine’s power system with combinations of missiles and hundreds of drones, repeatedly mangling equipment and cutting off power. The cold imposed on Ukrainian homes is especially hard on former prisoners of war held in Russia, where cold is routinely employed as a form of torture.

In the first two years of the war, keeping the grid flowing was a 24/7 job. But Ukrenergo has adapted to the impossible since then, says Vitaliy Zaychenko, Ukrenergo’s CEO, who somehow found a moment to speak with Spectrum via video call. Now, “we are more prepared for each attack. We have well-trained teams. We have support from Europe,” he says.

But the risk involved in repairing the grid remains unnerving. Last month a crew from DTEK, Ukraine’s biggest private-sector energy firm, was traveling between locations when it was targeted by a Russian drone. They heard the drone coming and escaped before their bucket truck was destroyed. Russian forces have employed “double tap” attacks against DTEK’s crews, targeting their power infrastructure with a follow-up strike designed to kill first responders—a practice confirmed by the U.N.

When Russia began targeting power infrastructure in October 2022, Brecht’s job shifted from high-level direction of grid planning and maintenance to near-constant triage and real-time system reengineering. Most weeks, Brecht spent several days in the field, crisscrossing the country to coordinate work at smashed substations. Brecht would often be found on site figuring out how to restart power using whatever equipment was available. “It was a unique decision every time,” says Zaychenko.

Zaychenko noted Brecht’s “genius” for finding creative grid fixes, his passion and leadership skills, and his credibility with power brokers in Ukraine and abroad. Brecht scoured the globe sourcing critical replacement parts, including stockpiled or older equipment from international utilities. Transformers, which can take a year or more to source, are especially precious.

When the right equipment wasn’t forthcoming, Brecht figured out how to make do. For example, he would deploy transformers from Western Europe rated for 400 kilovolts to restart a 330-kV circuit. He would adapt transformers designed for 60-hertz alternating current for emergency use on Ukraine’s 50-Hz grid. “He would find a way,” says Zaychenko, who worked closely with Brecht for over 20 years.

Brecht’s assistant at Ukrenergo, Svitlana Dubas-Veremiienko, says he also contributed to the teams’ morale and confidence. She shared on Facebook that he smoked “like a locomotive” at the worst times, and yet exuded calm: “In his presence, chaos subsided,” she wrote. Brecht was not easy to intimidate. “He was someone who never feared anything or anyone,” adds Tsaturian.

Brecht’s work proved so essential that Ukrenergo’s former Deputy CEO Andrii Nemyrovskyi recalls telling Ukraine’s Ministry of Defense in 2022 that the military must protect two people: Zaychenko, because he ran grid operations, and Brecht because “system operations requires that the system exists.” Last week, President Zelenskyy posthumously named Brecht a “Hero of Ukraine” for “strengthening the energy security of Ukraine under martial law.”

Ukraine’s Power Infrastructure Under Fire

Brecht joined Ukrenergo in 2002 after earning his degree in power engineering from Igor Sikorsky Kyiv Polytechnic Institute. Over the next 20 years, he held leadership positions in dispatching and grid planning and development. He joined Ukrenergo’s management board in June 2022 and served as its interim leader in 2024.

Brecht’s contributions to Ukraine’s wartime survival began with several key upgrades to Ukrenergo’s technical capabilities ahead of the February 2022 invasion. He reintroduced “live line” techniques, providing training and equipment that enable crews to work on circuits while they continue to carry power to homes and to sustain critical needs.

Brecht also led preparations for Ukraine’s disconnection from the Russian grid and synchronization with Europe’s. When the invasion began, Ukraine’s Minister of Energy at the time, Herman Halushchenko, had argued that switching from Russia’s grid to Europe’s was too risky, according to Tsaturian and Nemyrovskyi. But Brecht insisted—correctly, as hindsight has shown—that synchronizing with Europe would provide crucial stability and backup power. At his urging, the switch was completed in daring fashion during the first weeks of the invasion.

(Halushchenko was dismissed last year following longstanding allegations of corruption and Russian influence in Ukraine’s energy sector that gave way to indictments in November 2025 that have rocked President Zelenskyy’s government. In January, Halushchenko was detained while attempting to leave the country and charged with money laundering.)

A Ukrainian Electrical Engineer’s Final Day

Brecht’s final act of service followed the mass destruction of January 19—a day when Kyiv’s high temperature was –10° C. That night, Russian forces targeted Ukraine’s energy infrastructure with 18 ballistic missiles, a hypersonic cruise missile, 15 conventional cruise missiles, and 339 drones.

The impact included catastrophic damage at the 750-kV Kyivska substation, which feeds electricity to the capital and ensures cooling power for two nuclear power plants.

Brecht was leading a team of about 100 people who were undoing the damage when he made a deadly choice. He picked up a section of busbar—solid conduits that connect circuits within substations. It had been blasted to the ground and, unbeknownst to Brecht, was carrying lethal voltage. It’s unclear whether its circuit was still connected, or if it had picked up voltage from another circuit.

Zaychenko says an investigation is ongoing to provide answers. “I don’t know why he touched this busbar. Maybe because of tiredness. Maybe something else,” he says. “He was trying to help the team to do this job quickly. It was a huge mistake and a huge loss for us.”
