The James Webb Space Telescope has been picking up little red dots in almost every image,
writes Quanta magazine. And now two teams of astronomers propose they're looking at a new astronomical object: a black hole star. It shines with the light of billions of suns — and hides a black hole in its core.
But Quanta adds that "not everyone agrees with this bold interpretation."
[Two Webb telescope surveys of distant objects included little red dots] for hours at a time. They tabulated precisely what shades of light were coming from each dot, and how bright the shades were... The bombshell discovery in the little red dot spectra was that the colors of hydrogen were smeared out across multiple shades. Usually, seeing such an effect means you're looking straight at an exposed black hole. Black holes whip hydrogen clouds around them at furious rates, with the clouds emitting slightly different colors depending on their speed...
Then, in the spring of 2025, [two of the paper's astronomers] de Graaff and Naidu's teams unveiled the two strangest dots yet... The new little red dots couldn't literally be stars — they were way too bright. And they didn't look much like black holes either. Black holes have an assortment of ringlike structures of different temperatures... Naidu and de Graaff concluded that they were[ looking at the first examples of something combining the vigor of a black hole with the outward appearance of a star: a black hole star... This black hole would pull gas around it, dramatically heating it and pushing light and energy outward, which would keep the outer layers of hydrogen from collapsing inward. In this way, the black hole would form the "engine" of the star, analogous to the fusion-powered core of our sun... "We are seeing the seed," Naidu said. "This is the birth of potentially every massive black hole in the universe."
"Astronomers have spent the last year in a lively debate about what's really going on," Quanta adds. And this week simulations using the Japanese Supercomputer ATERUI III "have explained the nature of the Little Red Dots without requiring any exotic assumptions," writes Phys.org — by conducting the most detailed cosmological simulations yet of conditions in the early universe:
The simulations show that the Little Red Dots are black holes growing at a rate that would be impossible today because of conditions in the early universe. The simulations show that in the early universe, intense far-ultraviolet (FUV) radiation from nearby galaxies suppresses star formation in gas clouds, so rather than forming many small stars, the gas can form a single supermassive star, which then collapses into a black hole seed.
The simulations show that, once formed, these black hole seeds are surrounded by dense gas disks. This environment traps radiation, enabling the black holes to grow at rates dozens of times faster than would be possible in the modern universe. The simulated properties of these rapidly growing black holes provide a good match to the Little Red Dots (LRDs) observed by the James Webb Space Telescope (JWST).

Neither OpenAI or Anthropic is acting responsibly, warned AI researcher Jacob Coxon when resigning last week from Anthropic. But just hours earlier, OpenAI VP of Research Aidan Clark had posted "For the first time, I am asking myself if things are moving too fast. I'm honestly not sure, but I am sure that it would be good for us to have an answer to 'What would a successful pace look like?'"
CNN noted Wednesday they're just some of the many AI insiders who are now concerned about the speed of research. Coxon even wrote that "The people building AI earnestly believe that it could kill us all by the end of the decade. This is not a marketing stunt. If anything, many executives and senior researchers will couch their phrasing in the press to sound sensible — but I hear the same people express fear privately."
In 10 days since, Coxon's post has been viewed more than 170 million times, warning that OpenAI and Anthropic are "racing straight to self-improving superintelligence and gambling with our lives." It's part of what CNN now calls "pressure on AI companies and governments to do something about the pace of development and safety," where "much of that pressure is coming from staffers inside the companies."
One staffer at a top AI company told CNN the fears of how AI could hurt humanity keeps them up at night. Another researcher who recently left a different AI company said it's a common subject of conversation at parties and social events in Silicon Valley. "You can't spend more than a few hours in this community without realizing that a very substantial number of people are really pretty worried about these sorts of outcomes," said the researcher. "A majority would say there's some chance of it killing everyone...." Dozens of Coxon's colleagues in the AI industry publicly supported his statements, with some making even more dire predictions... OpenAI CEO Sam Altman and SpaceXAI CEO Elon Musk agreed to Amodei's proposal to embed independent watchdogs at the AI companies...
"I would burn my equity to the ground in a heartbeat for a 1% higher chance we make it out of this situation alive. I expect a great many of my colleagues across the industry would as well," wrote Drake Thomas, who works on AI safety at Anthropic. "I promise you, we are actually just f**king scared, it's not galaxy brained marketing..." AI staffers told CNN that they fear that as AI gets better at training and improving itself, their leverage goes down, prompting today's urgency. "As we get into this recursive self-improvement loop, I think that might substantially reduce staff's bargaining power, because frankly, you'll be able to replace many of the staff with models that can do as good a job," the researcher who recently left a top AI company said.
Coxon posted Tuesday on X that Anthropic "largely initiated" the race to recursively self-improving AI, justifying it with "a belief in its inevitability." And then OpenAI "had to shed a bunch of dead weight like Sora," as he sees it, "because Anthropic was going for the jugular." (In fact, his specific disagreement with Anthropic's leadership was whether China and the U.S. could ever negotiate an alternative to their current race towards self-improving AI...)
In an informal "Ask Me Anything", Coxon responded to a question about when we'd see a Terminator-like malevolent AI by saying that "Skynet could go live in the 2030s if we aren't careful. ai-2027.com is a modern skynet story written a year ago and it's on track so far." Yet while AI development risks an end to humankind, "I do think that if we go slower we can take risk to 0%... But this requires radical action." He acknowledged there was still a possibility that the steady increases to model intelligence could suddenly plateau, but "They haven't so far, and it's just a few more steps up the ladder to hit the finish line."
To avoid stifling innovation, he recommends "prioritizing applications that actually improve people's lives [like healthcare discoveries], rather than immediately going for raw economic value or intelligence." But isn't mass unemployment a more pressing threat? "Things are coming so fast that unemployment would be a brief preliminary to deadly superintelligence."
To people who feel disempowered, Coxon offered his solidarity. "I also feel disempowered. Part of resigning was a feeling of hopelessness about the future. I would say — keep your eyes open as things get crazier and advocate for increased transparency into AI companies."
When asked if he'd start his own company now, Coxon said he had "No idea what I'm doing next."

In 2021, America approved $65 billion to fund broadband internet services as part of President Biden's Bipartisan Infrastructure Law. But Trump's administration announced they'd withhold funds from states with net neutrality protections...
States could object and sue the government, Ars Technica reported last October, "but even a successful lawsuit could take years and leave unserved homes without broadband for the foreseeable future." So where does that leave California's net neutrality laws? Ars Technica asks. California expect to spend about $1.4 billion to deploy broadband to 270,571 locations...
Similar to federal net neutrality rules repealed during the first Trump administration, California's law prohibits ISPs from blocking or throttling lawful traffic and says ISPs may not require fees from websites or online services to deliver or prioritize their traffic to Internet users. While the first Trump administration lost its attempt to preempt state net neutrality laws, the second Trump administration is trying to achieve a similar result by making federal broadband money conditional on whether states agree not to enforce net neutrality...
California and Illinois are the only states that haven't finalized their funding, according to the BEAD progress dashboard maintained by the National Telecommunications and Information Administration (NTIA)... California could try to continue enforcing its net neutrality law even while accepting the federal funding, a strategy that would involve another long court battle over its right to regulate broadband providers. This would be difficult, as the Trump administration is requiring states that accept grant funding to commit that they won't enforce net neutrality rules... [N]early 30 advocacy groups that focus on access to technology are treating the vote as a significant milestone and urged state leaders to defend California's net neutrality law in a letter yesterday...
Winning a court battle would become much more difficult after the state accepts the money [according to Paul Goodman, legal counsel for the Center for Accessible Technology]. Goodman said the CPUC should delay the vote and that California should file a lawsuit arguing that the NTIA-imposed condition is illegal. In addition to net neutrality, Goodman said California may be giving up other regulatory authority over companies, like AT&T and Verizon, because the NTIA requirement forbids rate regulation and "utility-style rules on broadband Internet service" in general... Goodman said the exemption from state laws would last for up to 14 years. This is because ISPs receiving grants would have four years to deploy the required broadband networks, and the extended period of performance lasts another 10 years... AT&T is already trying to get out of state obligations related to its basic phone service in California, as we've reported... [Also at stake is whether "ISPs themselves get to pick the price of the mandated low-cost broadband offerings," the article points out.]
The letter from 30 advocacy groups to California state leaders argues accepting the money "would set a dangerous precedent for the federal government to use federal funding as a cudgel that forces states in line with its agenda... If California were to allow this funding to be used as leverage, there is no telling what other resources the administration would confidently seek to exploit."
Thursday California's Public Utility Commission did vote to approve the plan, but a spokesperson earlier told Ars Technica their vote "does not address subgrantee agreements, or the conditions the NTIA requires be included in subgrantee agreements."

The Register reports:
When Microsoft's developers and engineers sit down to code, they can now choose to work in Rust, which Redmond has added to its list of canonical languages. "Rust now is a Tier One language at Microsoft, and that just means that it sits among C++, C# and TypeScript as the best supported languages for internal development in the company," explained Victor Ciura, Microsoft principal engineer for the Rust tooling team, during a keynote talk today at this year's annual RustConf, being held this week in Montréal. Ciura said Microsoft has "paved a path" of tools and processes that support local Rust development across the entire software development lifecycle.
Rust is no stranger at Microsoft and is already present in over 100 Microsoft project repositories. The company has built Oxidizer, a set of crates to build scalable services in Rust, which have been used to build and refine the Microsoft 365 core services such as Outlook, Word, Excel, OneDrive, and SharePoint. The Copilot tech stack also owes quite a bit to Rust... [C]ompany engineers built rustc_codegen_utc, a custom Rust compiler code-generation backend that wires the rustc compiler directly into the Microsoft Visual C++ internal toolchain for Windows... "The result is a unified code generation platform for Rust and C++ on Windows" [Ciura wrote in a blog post, noting that more than 100 Microsoft project repositories now build with rustc_codegen_utc.]
Still, Redmond running towards Rust is a welcome development. In his 2025 RustConf keynote, Microsoft Azure CTO Mark Russinovich noted that ~70 percent of Windows CVEs are memory issues.
"One of the things that I realized a long time ago is that no matter how much we really want to make C and C++ better, we can't make it as good as what Rust starts with," he said.

"Turns out, Silicon Valley isn't especially altruistic," writes the nonprofit education news site The 74. They're reading a new book promising "the inside story of how Big Tech catalyzed, co-opted, and ultimately came to capture computer science and AI education in America". Written by
New York Times business reporter Natasha Singer, Coding Kids: Big Tech's Battle to Remake Public Schools tells "the story of the nonprofit Code.org and its charismatic, Harvard-educated leader, Hadi Partovi," according to their review:
Thirteen years ago, Partovi... delivered a worrying message: Kids who didn't learn to write code would be left behind. And the long-term success of the United States economy depended on training these students to fill a million open tech jobs.... Fast-forward to 2026, and now we're dealing with AI, and tech is reading from a similar playbook.
Asked by The74's Greg Toppo, "Does this moment seem different to you?", Singer replies, "This moment is different, but also similar.
"We are in a moment in society where a lot of people have increased distrust of these huge tech companies, and we see a wave of parents pushing back against tech in schools. But we also see waves of people pushing back against Flock cameras, against data centers, that there's this feeling that tech has taken so much, and that people feel like they have lost control — that tech is being enacted on them... And parents are worried about the effects of unfettered tech access and kids' compulsive use of social media and phones, and so there's a different climate.
And yet there seems to be a disconnect in some ways with AI because you see that Microsoft and OpenAI and Anthropic and Google are all competing to get their AI tools into schools, and you see school districts across the country say "We've partnered with OpenAI." "We are a ChatGPT Pioneer School," or "We've partnered with Microsoft, and we're going to use 10,000 licenses of CoPilot." It's amazing to me. We have had these cycles of tech in schools where there are all these promises about the latest tech, laptops, learning apps, massive open online courses, virtual reality, big data's going to revolutionize schools and like democratize access to education for kids and get them these great career skills, and we keep having these cycles. My concern is that we don't learn anything.
One of the reasons I wrote this book is because it feels like we have collective amnesia. Now we're in the sixth or eighth cycle of this — and shouldn't we be asking questions about the push for AI in schools, based on what we've learned about the push for all the other things that came before?
Two Slashdot posts are cited in the book, both submitted by long-time Slashdot reader theodp (Slashdot UID #442,580), who even gets a shout-out in the book's "Acknowledgements" section (along with consumer advocate Ralph Nader).
Ironically, one member of Amazon's "Vine" program received a free copy of the book in exchange for a review — and apparently misunderstood its topic, writing that it made coding "feel approachable and even fun... [T]his is exactly the kind of book that could help a child become interested in technology without feeling overwhelmed by it. I particularly liked the way it encourages kids to be curious, experiment, and solve problems on their own. I would definitely recommend Coding Kids to parents, grandparents, or teachers looking for a good introduction to coding..."

Tuesday U.S. Space Force chief Douglas Schiess said his branch of the U.S. military operates "on-orbit weapons," reports Reuters, to defend "against space-enabled attacks." He promised "disciplined and responsible choices" when scaling America's orbital defense arsenal in the coming years.
NPR calls this week's reveleations "remarkable... after previous warnings about countries such as Russia possibly weaponizing a global frontier long agreed in treaties to be used for only peaceful purposes."
The revelation comes as the Trump administration puts a growing focus on space. In 2019, during his first term, Trump created the Space Force as a separate military branch. In his second term, he has announced the "Golden Dome" missile defense system, which includes plans to put U.S. weapons in space. Trump said last year that he expected the system would be "fully operational before the end of my term," which ends in January 2029, and have the capability of intercepting missiles "even if they are launched from space." Trump also has directed the Pentagon to pursue the space-based interceptors, in an executive order during the first week of his presidency. The Congressional Budget Office estimated that just the space-based components of the Golden Dome could cost as much as $542 billion over the next 20 years.
The Biden administration announced in 2024 that Russia was developing a space-based nuclear weapon that could loiter in space for long durations, then release a burst that would take out satellites around it. That kicked off a renewed debate on the idea of weapons in space at the United Nations. In April 2024, Russia vetoed a joint U.S.-Japanese resolution that would have called on all countries not to develop or deploy nuclear arms or other weapons of mass destruction in space, as banned under a 1967 international treaty that included the U.S. and Russia... The Russian delegation called the resolution hypocritical and a double standard and instead proposed a rival resolution to ban all weapons in space "for all time." It ultimately failed. Russia had argued that the United States and its allies opposed a ban on all weapons in outer space because they planned to deploy weapons there.
Reuters calls this "a landmark moment in space militarization," while noting that it's "aimed at deterring what U.S. officials describe as aggressive orbital activities from China and Russia, officials and analysts said."
The remarks this week by Washington's top military-space officials are part of "the increasing comfort level of the U.S. government to speak about aggressive actions in space" that has been building up in recent years, said Victoria Samson, chief director of space security and stability at the nonprofit Secure World Foundation. "We've gone from not talking about counter-space capabilities... to now saying flat-out we have weapons in space," Samson said. "The pendulum keeps on shifting over that way..."
"The acknowledgment of these space-control capabilities is fundamental to ensuring that we prevent deterrence from failing, and that we are postured and ready should deterrence fail to employ them effectively," Richard Palmer, the director of the Capability and Resource Integration Directorate at U.S. Space Command, said on Tuesday.... "The bottom line is that our joint force and our allied forces require space. Our economies require space," added Palmer. "We are ready in the U.S. to preserve that."
Reuters adds that Russia's Foreign Ministry issued criticism of America's move, saying "In pursuit of its narrow self-interests, Washington is ready to completely ignore the catastrophic consequences for humanity of any armed conflict in orbit."

Reuters reports that a former Google DeepMind employee "became the latest AI researcher to warn that the technology could 'kill all humans', saying time could be running out to avoid the outcome:
Public alarm about the potential danger posed by AI is growing, after Anthropic researcher Jacob Coxon said last week he had resigned, in part because the "people building AI earnestly believe that it could kill us all by the end of the decade." Anthropic scientist Evan Hubinger then responded to Coxon's comments, saying he was correct and that he believed there was a greater than 10% chance that AI could kill all humans within the next decade.
"I recently resigned from Google DeepMind, where I worked on AGI safety and alignment research," Bilal Chughtai wrote on X. "I earnestly believe that AI has the potential to kill us all, and that we might be running out of time to avoid this outcome." Chughtai, who co-authored research papers while at Google DeepMind, worked there as a research engineer and left the company in July 2026, according to his LinkedIn profile.
Meanwhile, Meta CEO Mark Zuckerberg "said it's up to each AI company to make sure its technology is safe," reports the Associated Press, "distancing himself from calls by rival companies for a coordinated slowdown in the development of advanced artificial intelligence.
AI companies are already motivated to develop their models in a safe way and face "significant liability" to prevent them from causing harm, Zuckerberg said. "Every lab has the responsibility and incentive to move at the pace required to train its models safely, and the ability to take its own actions to ensure that happens," he wrote on X... Zuckerberg said Meta delayed releasing its Muse AI agent for several months to ensure its safety and security. "We didn't call for everyone else to do this before we would," he said.
Companies should prioritize building safe AI models instead of systems that can automatically improve themselves, a function known as recursive self-improvement, Zuckerberg wrote. "Committing the significant majority of compute towards serving people rather than racing towards recursive self-improvement is one of the best ways to ensure we develop this technology safely."
But Zuckerberg also agreed that engaging independent evaluators and advisors "is industry best practice," adding that Meta Superintelligence Labs "already does this today in several areas because it helps produce better work...
"I believe the key to building a positive future for everyone is maintaining the right balance of power. This is within our power to do."

"Hackers ripped down a Flock camera above a roadway, made a near-complete copy of the data stored inside it, and shared the files with 404 Media and WIRED," according to an article published on both sites.
Though Flock has described its system as protected by on-device encryption, "The hackers were able to copy the camera's storage and recover an encryption key stored on the device, which unlocked videos of thousands of vehicle detections."
The hackers shared the material with 404 Media and the transparency nonprofit Distributed Denial of Secrets, which shared the data with WIRED. 404 Media and WIRED then analyzed those files as part of a joint investigation... [T]he joint analysis of the recovered data shows that software running on the device explicitly detects people as well as vehicles, license plates, and bicycles. The camera can produce dozens of images of a single passing vehicle and, according to several weeks of recovered logs, generated more than a million images. Its computer-vision software also sometimes isolated bumper stickers and other graphics, including, in one case, an American flag patch on a motorcyclist's saddlebag...
According to our analysis, the camera's logs recorded about 21 days of activity across several periods. During those windows, the device photographed roughly 50,200 vehicles and generated about 1.6 million images. On a typical day, it logged around 3,300 vehicles, with a high of 4,454... The software running on the camera explicitly detects people, something which is typically overlooked in discussions around Flock cameras. When it spots a person, it records where they appear in the image and how confident it is in the detection.
It was a collective calling itself stegan0gram that breached the cameras, according to the interview they did with Wired and 404 Media. "Why just destroy them when we can reverse engineer them and find the secrets of those spying on us?"

The New York Post reports:
A new app called Zuckoff can detect if a user is near someone with Meta's creepy AI-powered glasses, which have drawn criticism for enabling creeps to record video of women without their consent. Programmer Pawel Szydlowski says tales of dirtbags recording themselves perving on women or harassing strangers prompted him to launch the app...
Zuckoff — which detects Bluetooth signatures broadcast by smart glasses and can estimate their distance — has gained some 5,000 users since it hit Apple's App Store last month, according to Business Insider. "There's a need for such an application," the 30-year-old Polish techie told the outlet, adding that European Union regulators have contacted him for more info about his app. "We as a society have the right to at least know that someone is recording," Szydlowski said...
Earlier this month, the tech giant disabled thousands of glasses it found had been tampered with to keep a small light off that indicates the device is recording.
It's already #77 on the iPhone's list of best-selling utilities apps.
In a related story, "After accusations of selling 'perv glasses,' Meta prepares to sell a pair without a camera," writes TechCrunch, citing a report from The Information.
The glasses include six built-in microphones so users can communicate with the chatbot, as well as a button on the side of the glasses that, when pressed, activates the AI system... Meta's Reality Labs, which is responsible for developing its smart glasses line, is still losing a gargantuan amount of money, as its earnings report from April revealed.
In fact, Meta stock is off 13% over the last 12 months, reports Yahoo Finance. So Tuesday Meta announced subscription services for its social apps as "part of Meta's push to drive additional revenue from the billions it's investing in AI data centers and model development."
The plans, which start at $2.99 per month for single-product plans, $7.99 for individual bundles, and $14.99 for creator and business bundles, provide a number of features for users looking to get more out of their Instagram, Facebook, and WhatsApp accounts. Instagram Plus and Facebook Plus allow users to keep their stories up for 48 hours instead of 24, send animated super reactions and super hearts to stories, preview stories without showing up as a viewer in other users' lists, and more. WhatsApp Plus lets you share exclusive stickers, get exclusive ringtones for contacts, and pin up to 20 different chats.
Meta One also includes Core and Premium user plans that offer the features found in the single-product plans, along with increased AI usage limits for images and videos. The social media giant is also offering creator and business plans... that it says include capabilities such as enhanced profiles, automatic follow invitations to users that interact with your content, and increased access to the Meta Business Agent, which can respond on your behalf.
When Instagram head Adam Mosseri announced on Threads that the plans brought "more features and more AI across Instagram, WhatsApp, Facebook, and Meta AI," writer Joe Hill drew 13,300 likes for his response. "That's sweet--so pay a fee, get more AI, pay nothing, get a little less AI. Can we work out a deal where you pay ME and I get no AI at all?"

Targeting students and beginners, Adafruit released "CircuitPython" in 2017 (as a derivative of the MicroPython microcontroller-optimized programming language).
Now Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone) brings this update:
Adafruit has published CircuitPython Turbo, a workflow that compiles selected Python functions into native machine code on a computer, then loads them onto compatible microcontroller boards.
It builds on MicroPython's Native and Viper emitters. In a documented Metro RP2040 fixed-point Mandelbrot test, Viper cut computation time from 8.335 seconds to 0.423 seconds, a 19.71x speedup over bytecode. The rest of the application stays in Python. The guide includes benchmarks, source code and hardware demos. The speedup is for the measured computation, not the whole application.
"Turbo support is now included in the latest official CircuitPython builds for RP2040 and RP2350 boards..." explains Torrone's announcement at Adafruit.com. "The new Turbo in CircuitPython helps when the board spends time calculating: making neopixel effects, drawing fractals, processing audio, filtering sensor readings, or preparing lots of pixels. Those projects can get smoother animation, quicker responses, or room to do more things at once."
With Turbo, it's easier, better, and now even faster to make LED light up costumes that also reacts to sound at the same time, a sensor dashboard with animated graphics, or a tiny game doing physics while drawing the screen. Turbo speeds up the busy Python parts. It won't make a slow sensor or display connection faster... Your computer turns selected functions into instructions the chip can run directly. Python still handles the rest.
We have measured speedups, real display captures, and examples you can pull apart to see what happened. None of this arrived alone. CircuitPython, MicroPython, PyMCU, compiler tools, open hardware, and people sharing their work gave us pieces to connect. The Bao experiments take that idea somewhere else, handing calculations to four helper cores. Now we get to make those paths easier to use, compare results, and find the next useful thing. Maybe that's smoother animation, a responsive instrument, or an idea we haven't tried yet.
That's what I like about open source. Someone shares a piece, someone else sees a possibility, and we get to keep building it together.

"As parts of the Southern California coastline crumbled into the sea, slammed by intense waves and flooding in recent days, oceanographer Kim McCoy had one thing on his mind," reports the Los Angeles Times.
He was thinking about "the nuclear waste set in concrete on the beach near San Clemente at the shuttered San Onofre nuclear power plant."
"Rising sea levels, storm waves, El Niño which increases wave height ... these could wash away a section of the walkway that protects the San Onofre seawall, and the waste canisters are just 100 feet away from that," the former wave dynamics researcher and longtime advocate against beach storage of nuclear waste said. Most experts agree the risk of erosion damaging the nuclear waste storage system is extremely low in the near term. The plant's owner, Southern California Edison, has promised the California Coastal Commission to move the waste to higher elevation on-site if modeling shows sea level rise and erosion will start to pose a challenge. But the recent waves, fueled by Hurricane Marie far away in the Pacific, resurfaced the issue of the ultimate fate of the highly radioactive spent fuel that used to power the reactors. "At the moment, it is under control, I think it's essential to say that," said James Day, a geology professor at UC San Diego. "But geologically we must be thinking long term. The waste lasts for hundreds, if not thousands of generations...." [In 2103 some of the site's canisters' approach their intended 100-year lifespans, and the utility may have to start the transfer into new cansiters.]
The distinctive twin domes that once housed the reactor cores will start coming down early next year. But the 3.6 million pounds of high-level waste will stay in the coastal community indefinitely. How much of a safety hazard that is depends on whom you ask. "San Onofre is sitting on some fairly young rocks in a seismically active region," Day said at a recent symposium at the Scripps Seaside Forum in La Jolla, hosted by the Samuel Lawrence Foundation. "This is not the sort of place you would leave nuclear waste." Others noted that collapse of beach slopes could make the site more vulnerable to tsunamis. They spoke of the corrosive effects of the ocean air on the steel canisters that hold the waste...
Edison says its system will be safe for decades to come. "The maximum credible tsunami here would not even overtake the seawall," said Manuel Camargo, principal manager of decommissioning for Edison, standing on the concrete pad that holds the steel waste storage canisters. "The maximum credible earthquake, somewhere around a 7.0 magnitude, would produce something about half of what this system is designed to withstand...." Edison is bolstering a path below the seawall. Based on state data from the California Ocean Protection Council, the seawall would not be inundated before 2050, Camargo said...
Plans for a deep geological repository beneath Yucca Mountain in Nevada crumbled in the face of local opposition in 2011. Utilities around the U.S. now sue the federal government every year to recoup their storage expenses because the Department of Energy has not come through on its promise. The lawsuits cost taxpayers $2 million a day, according to Camargo.
