A Fusion Energy Breakthrough? Watch Live as US Scientists Make Major Announcement

A fusion reactor at Lawrence Livermore National Laboratory may have reached a critical milestone.

Scientists at Lawrence Livermore National Laboratory may have achieved a remarkable new high point for fusion reactions, generating even more energy than was pumped in during a recent experiment, according to a report by the Financial Times.

The publication suggests scientists «with knowledge of preliminary results from a recent experiment» have discussed the result and analysis is ongoing. A major announcement is scheduled to take place at LLNL on Tuesday, Dec. 13. It’s expected to be livestreamed by the Department of Energy at approximately 7 a.m. PT.

The National Ignition Facility operates an «inertial confinement fusion» experiment, which sees almost 200 lasers fired directly at a tiny capsule of hydrogen. According to Nathan Garland, a physicist at Griffith University in Australia, the lasers create a plasma around the capsule which eventually starts an implosion — these conditions allow for fusion reactions to take place.

Fusion is the reaction that powers our sun and it works by smashing two atoms together. This requires extreme pressure and extreme heat but trying to recreate the conditions in a lab is «super difficult,» noted Garland.

The energy released by fusing two atoms together is massive and, importantly, releases no carbon dioxide. Unlike fission — splitting atoms — used in nuclear power plants, fusion also leaves behind no radioactive waste and there’s no risk of meltdown, either. In short, if we could harness fusion power, it would revolutionize energy, allowing us to generate clean power without pumping greenhouse gases into the atmosphere.

If the FT report and chatter on social media is correct, scientists at LLNL could have achieved «fusion energy gain» which is denoted by the letter Q. In a fusion experiment, if Q > 1, then we’re on our way to a bona fide energy breakthrough, one that scientists have long been dreaming of reaching. «It is a big deal for sure, if true,» Garland said.

But, as with all science, it’s good to be cautious and not overhype results yet to be fully analyzed. We have been here before, after all. In 2013, reports swirled the NIF had achieved this exact feat. It wasn’t the case.

In more recent times, though, NIF has taken big strides toward achieving the goal. In August 2021, researchers reported they had, for a brief moment, re-created the power of the sun in a self-sustaining reaction. That’s a good pedigree and one that makes us here at CNET Science feel a little more confident in the rumors.

A spokesperson for LLNL told CNET «our analysis is still ongoing, so we’re unable to provide details or confirmation at this time» and provided a link to the media advisory — which, in all caps, suggests a «MAJOR SCIENTIFIC BREAKTHROUGH.»

The result won’t mean that we suddenly have an endless supply of energy. It’s likely the reaction that took place at NIF lasted for just a fraction of a second or even less. But this is the first step in a journey toward fusion energy as a viable, serious technology to power our world. It provides a proof of concept that fusion experiments like this can reach Q > 1.

So while I’m always cautious about throwing around the word «breakthrough» when reporting on cutting-edge science — especially in the realm of fusion energy — it does feel like it might be justified here. We’ll have to wait and see.

Updated Dec. 12: Changed sentence to «smashing two atoms together» rather than «heavy» atoms because hydrogen is, of course, a very light atom.

Sora Video Limits Got You Down? Pay Up for More, Says OpenAI

Sora has opened to everyone in the US, and OpenAI is now charging for extra AI video generations.

Soon after Sora dropped its invite-only requirement, OpenAI is already moving to monetize the popular AI video social media app. The company has introduced paid «video generation packs,» allowing you to purchase additional AI-generated videos after reaching the daily free limit.

Until now, you could generate around 30 videos a day for free or up to 100 for Pro accounts. Now, anyone who hits that cap will see a prompt to purchase extra «gens» through the App Store.

A small bundle of 10 extra generations costs roughly $4, according to Sora’s listing on Apple App Store, but OpenAI’s support page states that the exact credits used per video range based on factors like the video length and resolution.

OpenAI’s Bill Peebles confirmed the change in a post on X, citing increased demand and «unsustainable» economics as reasons behind the change. He also confirms the free quota options are likely temporary.

«Eventually, we will need to bring the free gens down to accommodate growth (we won’t have enough GPUs to do it otherwise!), but we’ll be transparent as it happens,» he wrote. «[i]n the meantime, enjoy the crazy usage limits.»

Even at full price, CNET smartwatch expert Vanessa Hand Orellana called the third-gen SE a «$250 steal that delivers nearly everything you’d want from a wearable, with surprisingly few compromises.» It’s equipped with the same S10 processor as the Series 11 and Ultra 3, and offers many of the same features, like fast charging, 5G connectivity and new wellness tools. Plus, the vibrant 40mm display is always on, so you can check the time with a glance. Other helpful features include onboard Siri, fall detection and a durable design that’s water-resistant up to 50 meters.

Surprise Twist: Apple’s Next iPhones Might Come in These 3 Unlikely Colors

Apple seems to be choosing a deep, earthy path for its upcoming phone colors.

From cosmic orange to coffee brown? Brown, purple and burgundy will be the available colors for the iPhone 18 Pro next September, if a leak out of China proves true.

Depending on your language translator, brown could mean simply «brown» or «coffee brown,» but you get the general idea. The tidbit comes from regular leaker Digital Chat Station’s post on the Chinese microblogging platform Weibo. The post also says that black will not be an available color for the iPhone 18 Pro.

A representative for Apple did not immediately respond to a request for comment.

The iPhone 17 Pro comes in cosmic orange, deep blue and silver.

The Apple release schedule for the iPhone 18 series has been shifting, but the latest intel reports that the iPhone 18 Pro, iPhone 18 Pro Max and iPhone Fold will launch in September 2026. The iPhone 18 and iPhone 18e will follow in the spring of 2027.

If Digital Chat Station’s leak is accurate, the iPhone 18 Pro would be the first Pro edition in years without a color resembling black, white or silver.

Here are the colors for the iPhone Pro dating back to its introduction in 2019:

2019: iPhone 11 Pro/Pro Max: Midnight Green, Space Gray, Silver, Gold
2020: iPhone 12 Pro/Pro Max: Graphite, Silver, Gold, Pacific Blue
2021: iPhone 13 Pro/13 Pro Max: Graphite, Gold, Silver, Sierra Blue, Alpine Green (March 2022)
2022: iPhone 14 Pro/14 Pro Max: Space Black, Silver, Gold, Deep Purple
2023: iPhone 15 Pro/15 Pro Max: Black Titanium, White Titanium, Blue Titanium, Natural Titanium
2024: iPhone 16 Pro/16 Pro Max: Black Titanium, Natural Titanium, White Titanium, Desert Titanium
2025: iPhone 17 Pro/17 Pro Max: Cosmic Orange, Deep Blue, Silver

Not offering any version of black for Pro models might seem counterintuitive, since the iPhone 16 Pro Max black titanium version has been a big seller, and black has also been popular with iPhone 17 shoppers. But a lack of black has not hurt iPhone 17 Pro sales.
