Seattle has enacted a one-year moratorium on new datacenters, making it the largest U.S. city to do so as the backlash against AI infrastructure grows across the country. The city council voted unanimously in favor of the ban. The Guardian reports: Lawmakers have framed the pause as an opportunity to draft regulations specifically targeting the electricity-hungry datacenters being built nationwide to serve the AI sector, and to protect local residents from environmental risks and rising electricity bills. According to Seattle mayor Katie Wilson, the moratorium will also let city officials determine whether datacenters are a "good use of urban land," and potentially impose new stipulations on their approval, such as requiring developers to invest in local transit and housing initiatives in exchange for construction permits. "There are times when public pressure forces elected officials to do something they don't want to do, but in other cases, public pressure just supports and helps to spur on elected officials to do things that they already want to do," said Wilson. "I think this was one of those latter cases." [...] An amendment to the moratorium that passed unanimously last week allows existing datacenters in Seattle to apply for expansions requiring up to 20 megawatts of additional power during the year-long pause. Activists are concerned that the provision may lead to a spike in datacenters' demand for power while the moratorium is in place, and may undermine the premise of the pause. Lawmakers justified the amendment as a way to differentiate between the datacenters that already exist in Seattle and serve a civic purpose, like those powering health facilities and emergency-call systems, from large-scale centers designed to serve the AI sector.

An anonymous reader quotes a report from ComputerWeekly: Microsoft has issued patches for about 200 flaws in its latest monthly Patch Tuesday drop, blasting past a previous record high of almost 170 common vulnerabilities and exposures (CVEs) set in October 2025. Among a great many others, the latest update from Redmond fixes a total of 32 critical CVEs and three zero-day flaws. Dustin Childs, head of threat awareness at TrendAI's Zero Day Initiative, said: "We are heading into a high-stakes summer for cyber security. June's record-shattering drop ... is a stark warning that AI is supercharging flaw discovery at an uncontrollable scale. The current number of CVEs shipped by Microsoft this year exceeds the total number of CVEs shipped in all of 2018. It is extraordinary that Microsoft can produce so many patches in a single month, and I expect many testers are wondering what quality issues may exist." And with the addition of hundreds of CVEs in Google Chrome and Microsoft Edge (Chromium) and other third-party flaws taking the total to almost 600, Chris Goettl, vice president of security product management at Ivanti, said talk of a 'Patch Apocalypse' was no longer unwarranted. "We are in the Patch Apocalypse. The Patch Apocalypse is now," said Goettl. "This is not intended to be a scare tactic. It is meant to outline the challenge that many organizations were anticipating, but the new generation of LLMs [Large Language Models] has accelerated significantly in the first half of 2026." "There are going to be more CVEs resolved by vendors at a faster and more continuous pace than we have ever seen previously. Unfortunately, this will also include more zero-day and n-day exploits than previously seen as well. The window from release from a vendor to exploitation had already shortened to five days as of 2023 threat intelligence data." Goettl said that many suppliers have acknowledged the need to use AI tools in their security research to identify and resolve flaws, with Oracle, Google Chrome and Mozilla all upping the cadence of their updates. Whether or not Microsoft follows suit remains to be seen.

Commonwealth Fusion has published five peer-reviewed papers laying out the physics case for ARC, its planned 400 MW fusion power plant, which would follow the company's smaller SPARC tokamak now under construction. The papers suggest ARC could produce more energy than it consumes using high-temperature superconducting magnets, molten-salt heat extraction, and 15-minute fusion pulses. Ars Technica reports: ARC will be a tokamak that hosts fusion between hydrogen's two heavier isotopes, deuterium and tritium. This reaction results in a helium nucleus and releases a neutron and radiation. The helium transfers heat to the plasma, maintaining the conditions needed for fusion, but it is otherwise a waste product, referred to as "ash" in the fusion context. The neutron and radiation, however, are put to use. Part of that use is simply imparting energy into a blanket of molten salt that surrounds the fusion chamber. That energy, in the form of heat, will be used to drive a turbine that produces the electricity. The molten salt includes lithium ions; when one lithium isotope absorbs a neutron, it decays into more helium, plus tritium that can be used as fuel for the reactor. There are isotopes present that will also release additional neutrons, allowing this process to generate sufficient fuel. Overall, the present design of ARC is expected to produce about 1.13 GW of fusion power, with 500 MW of that extracted as electricity. Some of that (100 MW) will be needed to power the plant's operations, leaving 400 MW to be sent to the grid. The rest of the energy is either kept in the tokamak to maintain the fusion reactions or lost due to inefficiencies in the heat and energy transfer of the system. There's a lot of uncertainty about these numbers; the 1.13 GW is just the center of a range of potential values running from 900 MW to 1.3 GW, so the 400 MW output may need to be adjusted up or down accordingly. Some of that 400 MW comes during periods where fusion is not occurring. The nuclear reactions will occur within 15-minute-long periods that will be interspersed with one minute resets. The resets are meant to be kept short enough that nothing has much of a chance to cool down before it gets heated up again -- thermal inertia will let it continue generating power. That will be one of the key differentiators with SPARC, which doesn't have the heat extraction needed to maintain stable fusion for these long time periods, and so can't maintain the near constant temperatures needed for reliable power generation. It's inevitable that parts of the device will be exposed to radiation and perhaps fusion plasma. The inner walls of the reactor will be shielded by tungsten, which will limit erosion by the conditions. Meanwhile, the vacuum vessel is designed to be replaced every one to two years. The papers note that this flexibility will allow them to make some design changes even after ARC is built. To enable this, the whole tokamak is meant to split in half for maintenance.

NASA has named Randy Bresnik, Luca Parmitano, Frank Rubio, and Andre Douglas as the crew for Artemis III, which has been reworked from a moon-landing mission into a roughly two-week Earth-orbit test of lunar landers being built by SpaceX and Blue Origin. NBC News reports: Randy Bresnik, Luca Parmitano, Frank Rubio and Andre Douglas are expected to launch into Earth orbit next year, with the goal of testing two commercially developed lunar landers that are slated to carry astronauts to the surface of the moon during the Artemis IV mission in 2028. Bresnik will be the mission's commander, with Parmitano, an Italian astronaut with the European Space Agency, serving as the pilot. Douglas and Rubio will be mission specialists, and Bob Hines will train with the crew as a backup member. "This test flight will enable us to prove we can carry out highly choreographed operations with our partners across hardware interfaces, software propulsion systems and life support elements with crew in the high-stakes space environment," Jeremy Parsons, NASA's Artemis program manager, said during NASA's announcement on Tuesday. Bresnik has been to the International Space Station twice, most recently as commander of an expedition in 2017. A retired U.S. Marine colonel, he was selected as a NASA astronaut in 2004. Bresnik has helped oversee development and testing of spacecraft for the Artemis program as an assistant to the chief of the Astronaut Office, which manages astronaut training and operations. Parmitano has also done two stints on the ISS and served as commander of an expedition in 2019. He has completed a total of six spacewalks and also performed the first live DJ set in orbit. Before becoming an astronaut, Parmitano was a test pilot for the Italian air force. For Rubio, a physician with 28 years of service in the Army, Artemis III will be his second trip to space. From 2022 to 2023, he spent 371 days on the space station, breaking the record for longest-duration spaceflight by an American, according to NASA. Douglas is the only crew member making his spaceflight debut. An engineer who previously worked on space exploration and robotics at Johns Hopkins University Applied Physics Lab, he became a NASA astronaut in 2022. Douglas was the backup crew member for the Artemis II mission around the moon earlier this year. He told NBC News in an interview after Tuesday's announcement that the role had at times been a challenge. "It was hard to figure out how do you balance getting ready to go, not go, all that stuff," he said. "But to go now is just fantastic."
