‘Phenomenal breakthrough’: Nuclear fusion test sparks high-energy hopes

A laser blast in California creates a miniature sun for a tiny fraction of a second and ignites a self-sustaining chain reaction.

For an almost imperceptible fraction of a second on Aug. 8, massive lasers at a government facility in Northern California re-created the power of the sun in a tiny hot spot no wider than a human hair. The result is a significant step forward in the pursuit of nuclear fusion, a long-sought-after panacea for many energy and environmental challenges.

The experiment took place at the National Ignition Facility, which takes up the space of three football fields at the campus of the Lawrence Livermore National Laboratory on the eastern edge of the San Francisco Bay metroplex. Powerful lasers there were focused onto a target the size of a BB, resulting in a reaction that threw off over 10 quadrillion watts of power.

Remarkably, that’s about 6% of the total energy of all the sunshine striking Earth’s surface at any given moment, although the powerful burst only lasted for 100 trillionths of a second. Even in that minuscule timeframe, though, scientists observed a big breakthrough: The hotspot was able to ignite a self-sustaining chain reaction, fusing more hydrogen atoms together and continuing the process of energy generation, like an internal combustion engine burning through one molecule of fuel after another to keep going.

Achieving this ignition point is a key milestone in the roadmap to fusion power.

«This phenomenal breakthrough brings us tantalizingly closeto ademonstration of ‘net energy gain’ from fusion reactions — justwhenthe planet needs it,» said Arthur Turrell, physicist and author of The Star Builders: Nuclear Fusion and the Race to Power the Planet, in a statement.

Nuclear power plants today are fueled by thereaction from nuclear fission, the process of splitting atoms to createenergy. Fusion is just the opposite: merging hydrogen atomsinto helium the same way the sun does, releasing gobs of energy in theprocess. Fusion is a sort of holy grail, because theoretically it wouldprovide a limitless source of clean energy with fewer safety and wasteconcerns compared to fission reactors.

For decades now, dozens offacilities have been experimenting with different methods. The challenge isn’tjust to achieve fusion, but to do so in a way that doesn’t require moreenergy to create the reaction than is produced as a result.

This month’s experiment was still a net negative in terms of energy in versus energy out, but it puts the science on the threshold of breaking even.

Lawrence Livermore National Laboratory reports that while a final analysis still needs to be peer reviewed, the initial data showed that the results yielded eight times the energy output of experiments done earlier this year and 25 times that seen in 2018.

«For reference this [is] about 1000x more energy output than we were getting when I joined the project 10 years ago,» project physicist Jayson Luc Peterson added on Twitter.

Jeremy Chittenden, co-director of the Center for Inertial Fusion Studies at Imperial College London, said in a statement that improvement in fusion energy output has accelerated over the past year, «suggesting we may soonreach moreenergy milestones, such as exceeding the energy input fromthe lasersused to kick-start the process.»

Interestingly, the National Ignition Facility is not primarily meant as a tool for fusion energy development, but rather for nuclear weapons research. Chittenden says the result should spur on other efforts focused on creating clean power.

«We have now proven it is possible to reach ignition, givinginspiration to other laboratories and start-ups around the world workingon fusion energy production to try to realize the same conditionsusinga simpler, more robust and above all cheaper method.»

Google Could Revive Last Year’s Bright Pink Color for the Pixel 10a

Google’s upcoming Pixel 10a is expected to launch in February with some new colors, including one popular ask.

The Google Pixel 9a is one of Google’s most affordable Pixel phones, and it includes one of the most frequently requested colors — bright pink. With the Google Pixel 10a rumored to launch in February, we’re already getting a hint at the colors the new model will come in.

According to Roland Quandt, a regular mobile leaker on Bluesky, the Google Pixel is expected to be offered in obsidian (black), berry (pink), fog (light gray), and lavender colors. However, it’s the berry hue that is intriguing customers.

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

«I always love to see phones come in vibrant colors, and it’s especially welcome in more budget-friendly options,» said Abrar Al-Heeti, senior technology reporter at CNET. «Yes, we tend to slap a case on our phones anyway, but just knowing your phone touts a bold color can make it feel like more of a statement piece, rather than a bland piece of tech.»

Pink is one of the most requested color options for the Pixel phones. CNET sister site Mashable loved the color when it debuted on the Pixel 9. Phone rivals like Apple and Samsung are usually expected to offer a pink color option in their flagship and midrange phone lineups, so it’s not surprising to see the berry color on the Pixel 10a.

«I’ll say that Google loves having Pixel phones in pink,» said Patrick Holland, CNET managing editor. «The Pixel 9 and 9a come in peony (a bright, bold pink) and the 9 Pro in rose quartz (a more muted pink). The Pixel 10 series lacks any pinkish hues.»

Quandt also says that the Pixel 10a will have 128GB and 256GB storage models, and will launch in mid-February. That’s earlier than expected compared with the Pixel 9a, which was revealed in mid-March 2025 for a launch on April 10. In terms of specifications, we expect the Pixel 10a to be a modest upgrade compared with previous generations. According to leaks, the Pixel 10 is unlikely to feature a newer Tensor G5 chip, and it’s likely to retain the same overall design as the Pixel 9a.

One leaker, Mystic Leaks on Telegram, expressed disappointment and revealed additional specs, including the absence of a telephoto lens, UFS 3.1 storage, a Tensor G4 chip, a 2,000-nit display and no Magic Cue, which is Google’s AI feature for the Pixel 10.
