In a reversal from previous years, U.S. carbon emissions rose 2.4% in 2025 compared with the year before. NBC News reports: The increase in greenhouse gas emissions is attributable to a combination of a cool winter, the explosive growth of data centers and cryptocurrency mining and higher natural gas prices, according to the Rhodium Group, an independent research firm. Environmental policy rollbacks by President Donald Trump’s administration were not significant factors in the increase because they were only put in place this year, the study authors said. Heat-trapping gases from the burning of coal, oil and natural gas are the major cause of worsening global warming, scientists say.

American emissions of carbon dioxide and methane had dropped 20% from 2005 to 2024, with a few one- or two-year increases in the overall downward trend. Traditionally, carbon pollution has risen alongside economic growth, but efforts to boost cleaner energy in recent years decoupled the two, so emissions would drop as gross domestic product rose. But that changed last year with pollution actually growing faster than economic activity, said study co-author Ben King, a director in Rhodium’s energy group. He estimated the U.S. put 5.9 billion tons (5.35 billion metric tons) of carbon dioxide equivalent in the air in 2025, which is 139 million tons (126 million metric tons) more than in 2024.

The cold 2025 winter meant more heating of buildings, which often comes from natural gas and fuel oil that are big greenhouse gas emitters, King said. A significant and noticeable jump in electricity demand from data centers and cryptocurrency mining meant more power plants producing energy. That included plants using coal, which creates more carbon pollution than other fuel sources. A rise in natural gas prices helped create an 13% increase in coal power, which had shrunk by nearly two-thirds since its peak in 2007, King said.

An anonymous reader quotes a report from the Guardian: Screen time spent gaming or on social media does not cause mental health problems in teenagers, according to a large-scale study. […] Researchers at the University of Manchester followed 25,000 11- to 14-year-olds over three school years, tracking their self-reported social media habits, gaming frequency and emotional difficulties to find out whether technology use genuinely predicted later mental health difficulties. Participants were asked how much time on a normal weekday in term time they spent on TikTok, Instagram, Snapchat and other social media, or gaming. They were also asked questions about their feelings, mood and wider mental health.

The study found no evidence for boys or girls that heavier social media use or more frequent gaming increased teenagers’ symptoms of anxiety or depression over the following year. Increases in girls’ and boys’ social media use from year 8 to year 9 and from year 9 to year 10 had zero detrimental impact on their mental health the following year, the authors found. More time spent gaming also had a zero negative effect on pupils’ mental health. “We know families are worried, but our results do not support the idea that simply spending time on social media or gaming leads to mental health problems — the story is far more complex than that,” said the lead author Dr Qiqi Cheng.

The research, published in the Journal of Public Health, also examined whether how pupils use social media makes a difference, with participants asked how much time spent chatting with others, posting stories, pictures and videos, browsing feeds, profiles or scrolling through photos and stories. The scientists found that actively chatting on social media or passive scrolling feeds did not appear to drive mental health difficulties. The authors stressed that the findings did not mean online experiences were harmless. Hurtful messages, online pressures and extreme content could have detrimental effects on wellbeing, but focusing on screen time alone was not helpful, they said.

New York Governor Kathy Hochul is proposing first-of-its-kind legislation that would require 3D printers sold in the state to include built-in software designed to block the printing of gun parts used to make “ghost guns.” The plan would also add criminal penalties for making 3D-printed firearms and hold printer owners or manufacturers liable if safety controls aren’t in place. 3D Printing Industry reports: “From the iron pipeline to the plastic pipeline, these proposals will keep illegal ghost guns off of New York streets, and enhance measures to track and block the production of dangerous and illegal firearms in our state,” Hochul said.

In addition to mandating printer-level safeguards and restricting access to CAD files, the proposed legislation would require law enforcement agencies to report any recovered 3D printed firearms to a statewide database. The measure also includes a provision requiring commercial gun manufacturers to redesign pistols so they cannot be easily converted for automatic fire. “These illegal firearms are being manufactured in homes and used in crimes right now, which is why I have been working with my colleagues in Albany and the private sector over the past several years to stop their proliferation. Passing these measures will reduce crime and strengthen public safety for all New Yorkers,” said Manhattan District Attorney Alvin Bragg.

Iran has imposed one of the longest nationwide internet shutdowns in its history, cutting more than 92 million people off from connectivity for over a week as mass anti-government protests continue. TechCrunch reports: As of this writing, Iranians have not been able to access the internet for more than 170 hours. The previous longest shutdowns in the country lasted around 163 hours in 2019, and 160 hours in 2025, according to Isik Mater, the director of research at NetBlocks, a web monitoring company that tracks internet disruptions.

Mater said that the current shutdown in Iran is the third longest on record, after the internet shutdown in Sudan in mid-2021 that lasted around 35 days, followed by the outage in Mauritania in July 2024, which lasted 22 days. “Iran’s shutdowns remain among the most comprehensive and tightly enforced nationwide blackouts we’ve observed, particularly in terms of population affected,” Mater told TechCrunch.

The exact ranking depends on how each organization measures a shutdown. Zach Rosson, a researcher who studies internet disruptions at the digital rights nonprofit Access Now, told TechCrunch that according to its data, the ongoing shutdown in Iran is on a path to crack the top 10 longest shutdowns in history.

Kathleen Kennedy is stepping down as president of Lucasfilm. Although she will continue as a producer for several Star Wars projects, including upcoming movie The Mandalorian and Grogu, the company will now be helmed by a duo in Dave Filoni and Lynwen Brennan. It’s a big changing of the guard for Star Wars fans, and marks the start of a fresh chapter for the sci-fi universe. 

Before taking over at Lucasfilm, Kennedy had seen great success as a producer with a couple little films you may have heard of: E.T. and Jurassic Park. She became Lucasfilm’s president in 2012 when the company was acquired by Disney. At that point, it had been several years since the last Star Wars movie; Revenge of the Sith closed out the generally panned prequel trilogy in 2005. Fans’ best option for Star Wars content was The Clone Wars, a standalone film and animated series which were well-regarded but primarily popular among the hardcore devotees rather than reaching the widespread cultural relevance of the prior feature films. 

During Kennedy’s tenure, Star Wars returned to the big screen with The Force Awakens in 2015. Although that J.J. Abrams-led trilogy was also a roller coaster for many fans, it marked a renaissance for the franchise. Lucasfilm embarked on two standalone movies in Rogue One and Solo, which generated yet more buzz and more money for the company. Star Wars got the full cinematic universe treatment, with critically acclaimed live-action television projects and several new video games. The world fell in love with Baby Yoda. Ewan McGregor finally got to don his Obi-Wan Kenobi robe in a better vehicle. The franchise was back in the mainstream, with the budgets and expectations of media behemoth Disney at its back. No matter your feelings on the current state of Star Wars, it’s an impressive accomplishment by Kennedy and a big legacy that she leaves behind at Lucasfilm.

So now that Lucasfilm has arguably ended this phase on a high note, what’s next? Dave Filoni moving into the top spot isn’t much of a surprise. He’s long been seen by fans and seemingly by the company as George Lucas’ spiritual successor. Filoni was also the showrunner on The Clone Wars back in the day and has been involved in some capacity with many of the recent TV series, most notably The Mandalorian and Ahsoka. All that history means his new role of President and Chief Creative Officer is pretty expected, and the Star Wars faithful likely feel that they are in good hands. 

As the title implies, Filoni will be responsible for the artistic side of the operation, while as Co-President, Lynwen Brennan will be in charge of the business side. Brennan may be a less familiar name, but her tenure with Lucas’ businesses dates back to 1999 when she joined the legendary effects studio Industrial Light & Magic. Dividing the art and the commerce can yield good results if the two are able to find a good synergy. Star Wars has proven that it’s a moneymaker even when the films and series aren’t particularly well-received, but here’s hoping that Filoni and Brennan will each be able to maintain high standards for Lucasfilm and the Star Wars fandom.

An anonymous reader quotes a report from the BBC: Four astronauts evacuated from the International Space Station (ISS) have landed back on Earth after their stay in space was cut short by a month due to a “serious” medical issue. The crew’s captain, Nasa astronaut Mike Fincke, exited the spacecraft first, smiling and wobbling slightly on his feet before lying down on a gurney, following normal procedures. Nasa’s Zena Cardman, Japan’s Kimiya Yui and cosmonaut Oleg Platonov followed, waving and beaming at cameras. “It’s so good to be home!”, said Cardman.

It is the first time astronauts have been evacuated due to a health issue since the station was put into Earth’s orbit in 1998. The team, known as Crew-11, will now receive medical checks before being flown back to land after the splash down off the coast of California. In a news conference after splash-down, Nasa administrator Jared Isaacman said the sick astronaut is “fine right now” and in “good spirits.” Judging by past Nasa communications about astronauts’ health, it is unlikely that the identity of the crew member or details of the health issue will be released to the public.

Control of the ISS has been handed over to Russian cosmonaut Sergey Kud-Sverchkov and two other crew members. The astronauts arrived on the ISS on August 1 expecting to complete a standard six and a half month stay. They were due to come home in mid-February. But last week, a scheduled spacewalk by Fincke and Cardman was called off at the last minute. Hours later, Nasa revealed a crew member had become ill.

Reports suggest ASUS has effectively ended production of NVIDIA’s RTX 5070 Ti and 5060 Ti 16GB GPUs due to a severe memory crunch driven by AI infrastructure demand, even as NVIDIA insists it’s still shipping all GeForce SKUs. YouTube channel Hardware Unboxed broke the news in its most recent video where it states ASUS “explicitly” told them the RTX 5070 Ti is “currently facing a supply shortage” and has “placed the model into end of life status.” The shift leaves PC gamers facing fewer high-VRAM options just as modern games increasingly demand more than 8GB. Engadget reports: Hardware Unboxed also spoke to retailers in Australia, who told the channel the 5070 Ti is “no longer available to purchase from partners and distributors,” adding they expect that to be the case throughout at least the first quarter of the year. The 5060 Ti 16GB “is almost done as well,” with ASUS stating it no longer plans to produce that model going forward either. Both GPUs are 16GB models, making them more expensive to produce in the current economic climate. And while there might be some hope of the 5070 Ti and 5060 Ti 16GB returning later this year, the channel suggests both are unlikely to make a comeback. NVIDIA will reportedly focus on 8GB models like the RTX 5050, 5060, and 5060 Ti 8GB, with the 12GB 5070 set to stick around for now. The 5080 and 5090 are seemingly safe as well, as more expensive, higher margin models, they offer more space for manufacturers to absorb component price increases.

“Demand for GeForce RTX GPUs is strong, and memory supply is constrained. We continue to ship all GeForce SKUs and are working closely with our suppliers to maximize memory availability,” a NVIDIA spokesperson told Engadget. The company did not say 5070 Ti and 5060 Ti 16GB are going out of production. However, it also didn’t confirm they’re sticking around either. ASUS did not immediately respond to Engadget’s comment request.

After a tumultuous 2025 that saw it lose around 4,000 employees, NASA finally has an operating budget for 2026, and one that largely preserves its scientific capabilities. On Thursday, the Senate passed an appropriations bill funding NASA, alongside the National Science Foundation and a handful of other federal agencies. 

Going into the appropriations process, the president called for a 24 percent year over year reduction to NASA’s total operating budget. As part of that plan, the White House wanted to reduce the Science Mission Directorate’s funding by nearly half, a move that would have forced NASA to cancel 55 ongoing and planned missions, including efforts like OSIRIS-APEX. The bill effectively rejects President Trump’s plan, reducing NASA’s total operating budget by just 1.6 percent year over year to $24.4 billion. 

Per the new appropriations, NASA’s science budget will stand at $7.25 billion, 1.1 percent less relative to fiscal 2024, while shuffling the remaining funds to focus on different priorities. For instance, the House and Senate allocated $874 million (+8.7 percent) for the agency’s heliophysics work; planetary sciences, which oversees missions like New Horizons, was cut to $2.5 billion (-6.5 percent) compared to 2024. At the same time, NASA’s STEM engagement office, which the president proposed eliminating, escaped unscathed with its funding maintained at parity.

“It’s almost everything we had been asking for, and it’s very encouraging to see a House and Senate run by the president’s own party agreeing that we need to keep investing in things like NASA science,” says Casey Drier, chief of policy at the Planetary Society, a nonprofit founded by Carl Sagan that advocates for the exploration and study of space. “It contains very clear and direct language that not only is this funding made available to these projects, but that it will be spent on the initiatives that Congress states.”

Lawmakers also rejected Trump’s effort to scuttle the Space Launch System after its third flight. NASA’s heavy-lift rocket is billions of dollars over budget, but remains — as of now — the only spacecraft ready to ferry astronauts to the Moon. Compared to the rest of NASA, the fate of the SLS was never really in doubt. Senator Ted Cruz (R-TX) secured funding for the rocket as part of Trump’s Big Beautiful Bill. “I’ve been saying for a long time you should never underestimate the political coalition behind the SLS, and I think that was very much validated this year,” says Drier. 

More importantly, it appears the Goddard Space Flight Center will be safe from further damage. Over the summer, the future of the facility, known for its work on projects like the James Webb Space Telescope, was put in jeopardy. By some estimates, the campus has lost a third of its staff due to workforce cuts, and dozens of buildings, including some 100 laboratories, have been shut down by management. One of the casualties was NASA’s largest library, which houses irreplaceable documents chronicling the history of the space race. As part of a “consolidation” effort, many of those documents will be thrown out.

Under the appropriations bill, the Senate has directed NASA to “preserve all the technical and scientific world-class capabilities at Goddard.” It has also instructed the agency to ensure employees of the Goddard Institute for Space Studies are able to continue their work with “minimal disruption.” The New York-based office, one of America’s leading climate labs, was sent into limbo last spring after the Trump administration moved to shut it down. 

The bill also provides a lifeline for NASA’s to bring back samples of Martian dirt collected by the Perseverance rover. Congress has effectively cancelled the official program tied to that ambition, the Mars Sample Return (MSR), but has set aside $110 million for the agency to continue developing technologies for future science missions to the Red Planet. MSR advocates have argued the mission could lead to significant scientific discoveries, but Drier notes the program was “ripe for cancellation” after it became mired in mismanagement. 

“I worry MSR now has this stink of bloat, excess cost and threat of overruns that are really going to make it challenging to restart this without having a dramatically different approach,” says Drier, adding that deciding what to do with mission will likely be top of mind for the agency’s new administrator, Jared Isaacman. 

The 2026 budget leaves NASA with fewer resources. Even in areas where Congress allocated the same amount of funds as it did in 2024, the agency will need to do more with less due to inflation. Compared to the absolute blood bath that would have been Trump’s proposed budget, a marginal funding cut is the best case scenario given the circumstances, but the circumstances remain less than ideal. 

“There will be another presidential budget request coming out in the next couple of months,” Drier said. “They could do this all over again if they wanted to.”

In the immediate future, NASA and its employees are at least protected from the potential fallout of another impending government shutdown. Congress has until January 30 to fully fund the federal government, and as of earlier this week, it has yet to find a way forward on appropriations for agencies like the Department of Labor.
