In 2018 researchers claimed evidence of a lake beneath the surface of Mars, detected by the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument (or Marsis for short).
But new Mars observations “are not consistent with the presence of liquid water in this location and an alternative explanation, such as very smooth basal materials, is needed.” Phys.org explains
Aboard the Mars Reconnaissance Orbiter, the Shallow Radar (SHARAD) uses higher frequencies than MARSIS. Until recently, though, SHARAD’s signals couldn’t reach deep enough into Mars to bounce off the base layer of the ice where the potential water lies — meaning its results couldn’t be compared with those from MARSIS. However, the Mars Reconnaissance Orbiter team recently tested a new maneuver that rolls the spacecraft on its flight axis by 120 degrees — whereas it previously could roll only up to 28 degrees. The new maneuver, termed a “very large roll,” or VLR, can increase SHARAD’s signal strength and penetration depth, allowing researchers to examine the base of the ice in the enigmatic high-reflectivity zone. Gareth Morgan and colleagues, for their article published in Geophysical Research Letters, examined 91 SHARAD observations that crossed the high-reflectivity zone.
Only when using the VLR maneuver was a SHARAD basal echo detected at the site. In contrast to the MARSIS detection, the SHARAD detection was very weak, meaning it is unlikely that liquid water is present in the high-reflectivity zone.
The company that pioneered small launch has had a big year.
Rocket Lab broke its annual launch record with the Electron booster—17 successful missions this year, and counting—and is close to bringing its much larger Neutron rocket to the launch pad.
The company also expanded its in-space business, including playing a key role in supporting the landing of Firefly’s Blue Ghost mission on the Moon and building two small satellites just launched to Mars.
Uber is apparently feeling generous this holiday season. The company is launching family sharing for Uber One members, allowing individuals to add another adult to their account for free. They can also include an unlimited number of teens.
Anyone added to the membership can access all of the same benefits, including free delivery. They will also earn unique credits for rides. You can attach someone to your membership by clicking Account and then Uber One. From there, you can tap manage membership and then family sharing.

Uber is also giving members additional perks, like prioritized complimentary upgrades. The company claims that it will upgrade over one million rides for members between December 2 and 25. Plus, members traveling between today and Thursday for Thanksgiving should get 10 percent off if booking an Uber Black to or from an airport.
Tech lovers with an Uber One subscription will be happy to hear that you can get early access to $25 off if you spend $75 or more at Best Buy — through Uber Eats, of course.

In 2016, the legendary Japanese filmmaker Hayao Miyazaki was shown a bizarre AI-generated video of a misshapen human body crawling across a floor.
Miyazaki declared himself “utterly disgusted” by the technology demo, which he considered an “insult to life itself.”
“If you really want to make creepy stuff, you can go ahead and do it,” Miyazaki said. “I would never wish to incorporate this technology into my work at all.”
If you’re a creator in the market for a good-quality wireless microphone, DJI has the best deal we’ve ever seen on one of its most popular products. This Mic Mini bundle, which includes two mics, a receiver and two charging docks (plus two windscreens and other accessories), is already a good deal at the regular $119 price. For Black Friday, however, it’s marked down to just $66 for a savings of 45 percent. If you only need a single wireless mic, you can also grab a Mic Mini with a mic, receiver, charging dock and accessories for $45, or 49 percent off the regular price.
DJI’s Mic Mini deal includes two mic transmitters and a receiver that can be connected to a camera or phone. The bundle also includes a pair of charging docks, two windscreens, a splitter USB-C cable for charging, a 3.5mm camera audio cable, two magnetic clips, a smartphone adapter, a charging cable and a compact carrying case. Note that the charging case is not included in this deal. And if you want a simpler setup with just a single mic and receiver, plus all the other accessories, that’s also on sale for $45, or 53 percent off.
The wireless mics weigh just a third of an ounce and attach easily to subjects via magnets or clips. Everything pairs automatically and they offer high quality 24-bit, 20Hz to 20K Hz recording. They also connect easily to smartphones over Bluetooth and other DJI devices like the Action 5 Pro and Osmo Pocket 3 cams using DJI’s OsmoAudio direct connection. With a range of 1300 feet and 48 hours of battery life with the charger case, they’re an excellent addition to a creator’s bag of tricks.

In May MIT announced “no confidence” in a preprint paper on how AI increased scientific discovery, asking arXiv to withdraw it. The paper, authored by 27-year-old grad student Aidan Toner-Rodgers, had claimed an AI-driven materials discovery tool helped 1,018 scientists at a U.S. R&D lab.
But within weeks his academic mentors “were asking an unthinkable question,” reports the Wall Street Journal. Had Toner-Rodgers made it all up?
Toner-Rodgers’s illusory success seems in part thanks to the dynamics he has now upset: an academic culture at MIT where high levels of trust, integrity and rigor are all — for better or worse — assumed. He focused on AI, a field where peer-reviewed research is still in its infancy and the hunger for data is insatiable. What has stunned his former colleagues and mentors is the sheer breadth of his apparent deception. He didn’t just tweak a few variables. It appears he invented the entire study. In the aftermath, MIT economics professors have been discussing ways to raise standards for graduate students’ research papers, including scrutinizing raw data, and students are going out of their way to show their work isn’t counterfeit, according to people at the school.
Since parting with the university, Toner-Rodgers has told other students that his paper’s problems were essentially a mere issue with data rights. According to him, he had indeed burrowed into a trove of data from a large materials-science company, as his paper said he did. But instead of getting formal permission to use the data, he faked a data-use agreement after the company wanted to pull out, he told other students via a WhatsApp message in May… On Jan. 31, Corning filed a complaint with the World Intellectual Property Organization against the registrar of the domain name corningresearch.com. Someone who controlled that domain name could potentially create email addresses or webpages that gave the impression they were affiliated with the company. WIPO soon found that Toner-Rodgers had apparently registered the domain name, according to the organization’s written decision on the case. Toner-Rodgers never responded to the complaint, and Corning successfully won the transfer of the domain name. WIPO declined to comment…
In the WhatsApp chat in May, in which Toner-Rodgers told other students he had faked the data-use agreement, he wrote, “This was a huge and embarrassing act of dishonesty on my part, and in hindsight it clearly would’ve been better to just abandon the paper.” Both Corning and 3M told the Journal that they didn’t roll out the experiment Toner-Rodgers described, and that they didn’t share data with him.
DJI’s hyper-popular vlogging camera, the Osmo Pocket 3, is on sale at a near-record low at Amazon. You can pick one up now for $520 and save 35 percent ($279) off the regular price. This is likely the best deal you’re going to see for the Pocket 3 any time soon, given US tariffs that recently forced DJI to jack up the price.
When DJI’s Osmo Pocket 3 came out I said was “maybe the only vlogging camera you need.” To start with, it has a big one-inch sensor that boosts image quality considerably, particularly in low light. You also get a large swiveling touchscreen that makes it easier to switch between horizontal and vertical video. What really makes it great for vlogging, though, are the follow modes combined with face tracking. When working solo, you can simply set it up and it’ll rotate and tilt to follow you around — so you don’t have to worry about focus or even pointing the camera at yourself.
While there’s very little not to like about the Osmo Pocket 3, it’s not ideal for photos and is also quite expensive. But with the Black Friday deal and DJI’s Osmo Pocket 4 rumored to be arriving in December, it’s a great time to buy one — just act quickly as stocks are bound to run out.

An anonymous reader shared this report from the Guardian:
James and Owen were among 41 students who took a coding module at the University of Staffordshire last year, hoping to change careers through a government-funded apprenticeship programme designed to help them become cybersecurity experts or software engineers. But after a term of AI-generated slides being read, at times, by an AI voiceover, James said he had lost faith in the programme and the people running it, worrying he had “used up two years” of his life on a course that had been done “in the cheapest way possible”.
“If we handed in stuff that was AI-generated, we would be kicked out of the uni, but we’re being taught by an AI,” said James during a confrontation with his lecturer recorded as a part of the course in October 2024. James and other students confronted university officials multiple times about the AI materials. But the university appears to still be using AI-generated materials to teach the course. This year, the university uploaded a policy statement to the course website appearing to justify the use of AI, laying out “a framework for academic professionals leveraging AI automation” in scholarly work and teaching…
For students, AI teaching appears to be less transformative than it is demoralising. In the US, students post negative online reviews about professors who use AI. In the UK, undergraduates have taken to Reddit to complain about their lecturers copying and pasting feedback from ChatGPT or using AI-generated images in courses.
“I feel like a bit of my life was stolen,” James told the Guardian (which also quotes an unidentified student saying they felt “robbed of knowledge and enjoyment”.) But the article also points out that a survey last year of 3,287 higher-education teaching staff by edtech firm Jisc found that nearly a quarter were using AI tools in their teaching.
An anonymous reader shared this report from Forbes:
On November 20, at approximately 4 p.m. Eastern time, Napster held an online meeting for its shareholders; an estimated 700 of roughly 1,500 including employees, former employees and individual investors tuned in. That’s when its CEO John Acunto told everyone he believed that the never-identified big investor — who the company had insisted put in $3.36 billion at a $12 billion valuation in January, which would have made it one of the year’s biggest fundraises — was not going to come through.
In an email sent out shortly after, it told existing investors that some would get a bigger percentage of the company, due to the canceled shares, and went on to describe itself as a “victim of misconduct,” adding that it was “assisting law enforcement with their ongoing investigations.” As for the promised tender offer, which would have allowed shareholders to cash out, that too was called off. “Since that investor was also behind the potential tender, we also no longer believe that will occur,” the company wrote in the email.
At this point it seems unlikely that getting bigger stakes in the business will make any of the investors too happy. The company had been stringing its employees and investors along for nearly a year with ever-changing promises of an impending cash infusion and chances to sell their shares in a tender offer that would change everything. In fact, it was the fourth time since 2022 they’ve been told they could soon cash out via a tender offer, and the fourth time the potential deal fell through. Napster spokesperson Gillian Sheldon said certain statements about the fundraise “were made in good faith based on what we understood at the time. We have since uncovered indications of misconduct that suggest the information provided to us then was not accurate.”
The article notes America’s Department of Justice has launched an investigation (in which Napster is not a target), while the Securities and Exchange Commission has a separate ongoing investigation from 2022 into Napster’s scrapped reverse merger.
While Napster announced they’d been acquired for $207 million by a tech company named Infinite Reality, Forbes says that company faced “a string of lawsuits from creditors alleging unpaid bills, a federal lawsuit to enforce compliance with an SEC subpoena (now dismissed) and exaggerated claims about the extent of their partnerships with Manchester City Football Club and Google. The company also touted ‘top-tier’ investors who never directly invested in the firm, and its anonymous $3 billion investment that its spokesperson told Forbes in March was in “an Infinite Reality account and is available to us” and that they were ‘actively leveraging’ it…”
And by the end, “Napster appears to have been scrambling to raise cash to keep the lights on, working with brokers and investment advisors including a few who had previously gotten into trouble with regulators…. If it turns out that Napster knew the fundraise wasn’t happening and it benefited from misrepresenting itself to investors or acquirees, it could face much bigger problems. That’s because doing so could be considered securities fraud.”
Pew Research surveyed 5,022 Americans this year (between February 5 and June 18), asking them
“do you ever use” YouTube, Facebook, and nine of the other top social media platforms. The results?
YouTube 84%
Facebook 71%
Instagram 50%
TikTok 37%
WhatsApp 32%
Reddit 26%
Snapchat 25%
X.com (formerly Twitter) 21%
Threads 8%
Bluesky 4%
Truth Social 3%
An announcement from Pew Research adds some trends and demographics:
The Center has long tracked use of many of these platforms. Over the past few years, four of them have grown in overall use among U.S. adults — TikTok, Instagram, WhatsApp and Reddit. 37% of U.S. adults report using TikTok, which is slightly up from last year and up from 21% in 2021. Half of U.S. adults now report using Instagram, which is on par with last year but up from 40% in 2021. About a third say they use WhatsApp, up from 23% in 2021. And 26% today report using Reddit, compared with 18% four years ago.
While YouTube and Facebook continue to sit at the top, the shares of Americans who report using them have remained relatively stable in recent years… YouTube and Facebook are the only sites asked about that a majority in all age groups use, though for YouTube, the youngest adults are still the most likely to do so. This differs from Facebook, where 30- to 49-year-olds most commonly say they use it (80%).
Other interesting statistics:
“More than half of women report using Instagram (55%), compared with under half of men (44%). Alternatively, men are more likely to report using platforms such as X and Reddit.”
“Democrats and Democratic-leaning independents are more likely to report using WhatsApp, Reddit, TikTok, Bluesky and Threads.”
Theia crashed into earth and formed the moon, the theory goes. But then where did Theia come from? The lead author on a new study says “The most convincing scenario is that most of the building blocks of Earth and Theia originated in the inner Solar System. Earth and Theia are likely to have been neighbors.”
Though Theia was completely destroyed in the collision, scientists from the Max Planck Institute for Solar System Research led a team that was able to measure the ratio of tell-tale isotopes in Earth and Moon rocks, Euronews explains:
The research team used rocks collected on Earth and samples brought back from the lunar surface by Apollo astronauts to examine their isotopes. These isotopes act like chemical fingerprints. Scientists already knew that Earth and Moon rocks are almost identical in their metal isotope ratios. That similarity, however, has made it hard to learn much about Theia, because it has been difficult to separate material from early Earth and material from the impactor.
The new research attempts a kind of planetary reverse engineering. By examining isotopes of iron, chromium, zirconium and molybdenum, the team modelled hundreds of possible scenarios for the early Earth and Theia, testing which combinations could produce the isotope signatures seen today. Because materials closer to the Sun formed under different temperatures and conditions than those further out, those isotopes exist in slightly different patterns in different regions of the Solar System.
By comparing these patterns, researchers concluded that Theia most likely originated in the inner Solar System, even closer to the Sun than the early Earth.
The team published their findings in the journal Science. Its title? “The Moon-forming impactor Theia originated from the inner Solar System.”
After taking a break from the Playdate following Season Two and the wonderfully weird experience that was Blippo+, I finally dusted off my little yellow console this week and dove back in. And what better place to start than with a couple of games about cheese? Cheese ‘n Crackers and Say When! both hit the Playdate Catalog recently, but aside from the thematic similarity, they’re two very different games. As an extra treat (unrelated to cheese), I also picked up Ware-wolf Campfire Stories, a free game on itch.io that’s actually over a dozen bite-sized games in one.
Cheese ‘n Crackers
When it comes to snacking, everyone’s got their preferences. Some crave a savory blast of umami, while for others, a sweet treat might be what always hits the spot. Or maybe you’re like me, and if you have one, it needs to be followed by the other. Creating snacks that hit just right iswhat Cheese ‘n Crackers is all about.
In this Playdate game, you have what is essentially a neverending charcuterie board with all the fixins you could imagine. There are meats, cheeses, spreads, spices, vegetables, fruits and various types of crackers and breads to adorn with those toppings. You have to combine ingredients to make the perfect snacks for whatever group you’re serving that round. Each group — like the Speed Daters or Grandma’s Bridge Club — has a specific set of guidelines that may include favorites, dietary restrictions or aversions to certain tastes.

Scenic Route Software
While pairing ingredients is pretty intuitive, there are specific combinations that will earn you more points, so you’ll have to pay attention to descriptions of each food item. Or, you can turn to the Cheese ‘n Crackers Compatibility Spreadsheet for all of that information in one place. Yes, that exists, and it’s an intimidating work of culinary organization. Toppings will go bad if they sit out for too long, so you won’t want to waste too much time scouring the spreadsheet, but it’s still a relatively low-pressure game that you can play at your own pace. For the more competitive among us, though, there are leaderboards so you can challenge yourself with scores to beat.
Say When!
This is the more intense of our cheese games, with a Root Bear–like structure that sees you tending to a revolving door of restaurant patrons and trying to grate the perfect amount of cheese for their meals using the crank. And despite being called Say When!, your customers (very unhelpfully) will not actually say “when” to let you know you can stop cranking; you have to pay attention to their unique tells to know when they’re satisfied — the twitch of a mustache, a change in facial expression, etc.
A still from the Playdate game Say When! showing a man wearing dark sunglasses sitting at a table, with a dish in front of him. Grated cheese is pouring onto the dish from a cheese grater that floats above it
Smashtoad Studios
There’s a customer satisfaction meter at the top of the screen that will take hits any time you under- or over-serve cheese, or suffer if you’re moving too slowly, and once it’s down to the bottom, you’re fired. After each shift, you’ll be given the choice to use a modifier that can help you out in areas like customer satisfaction or getting the boss off your back. To mix things up, there are also mini-games that pop up in the middle of your shift. You might be furiously grating cheese and then have to switch gears and save the life of a choking customer, for example.
It’s fast-paced, it’s silly and it’s pretty hard to put down once you get going.
Ware-wolf Campfire Stories
While the Playdate Catalog has lots of great titles to choose from, there are plenty of gems not on there that are worth checking out too. One such example is Ware-wolf Campfire Stories, a unique package of 14 tiny games that’s free on itch.io. It’s the result of a collaboration between 15 developer teams — including the developers of Off-Planet Dreams, the Life’s Too Short series, Voidblazers and other popular Playdate titles.
Per the description:
In Ware-wolf Campfire Stories, 5 kids are sitting around a fire with their counselor telling spoooooky tales! Each story launches a separate game that you may win or lose…. with consequences.
It’s a cool format, and there’s some nice variety among the games, which each only take a few minutes to get through for the most part. They’re all of the spooky sort, so expect bats, ghosts and skeletons galore. It’s a nice way to get a taste of some of the many different game styles you’ll encounter on the Playdate, and maybe discover some developers whose games you haven’t yet checked out.

In October cryptologist/CS professor Daniel J. Bernstein alleged that America’s National Security
Agency (and its UK counterpart GCHQ) were attempting to influence NIST to adopt weaker post-quantum cryptography
standards without a “hybrid” approach that would’ve also included pre-quantum ECC.
Bernstein is of the opinion that “Given how
many post-quantum proposals have been broken and the continuing flood of side-channel attacks, any competent engineering evaluation will conclude that
the best way to deploy post-quantum [PQ] encryption for TLS, and for the Internet more broadly, is as double encryption: post-quantum cryptography on top of ECC.” But
he says he’s seen it playing out differently:
By 2013, NSA had a quarter-billion-dollar-a-year
budget to “covertly influence and/or overtly leverage”
systems to “make the systems in question exploitable”; in
particular, to “influence policies, standards and specification
for commercial public key technologies”. NSA is quietly
using stronger cryptography for the data it cares about, but
meanwhile is spending money to promote a market for weakened
cryptography, the same way that it successfully created decades of
security failures by building up the market for, e.g., 40-bit
RC4 and 512-bit
RSA and Dual EC.
I looked concretely at what was happening in IETF’s
TLS working group, compared to the consensus
requirements for standards-development organizations. I reviewed
how a call for “adoption” of an NSA-driven specification produced a variety of objections that weren’t
handled properly. (“Adoption” is a preliminary step before IETF standardization….) On 5 November 2025, the chairs issued “last call” for objections to publication of the document. The deadline for input is “2025-11-26”, this coming Wednesday.
Bernstein also shares concerns about how the Internet Engineering Task Force is handling the discussion, and argues that the document is even “out of scope” for the
IETF TLS working group
This document doesn’t serve any of the official goals in the TLS working group charter. Most importantly, this document is directly contrary to the “improve security” goal, so it would violate the charter even if it contributed to another goal… Half of the PQ proposals submitted to NIST in 2017 have been broken already… often with attacks having sufficiently low cost to demonstrate on
readily available computer equipment. Further PQ software has been broken by implementation issues such as side-channel attacks.
He’s also concerned about how that discussion is being handled:
On 17 October 2025, they posted a “Notice of Moderation for Postings by D. J. Bernstein” saying that they would “moderate the postings of D. J. Bernstein for 30 days due to disruptive behavior effective immediately” and specifically that my postings “will be held for moderation and after confirmation by the TLS Chairs of being on topic and not disruptive, will be released to the list”…
I didn’t send anything to the IETF TLS mailing list for 30 days after that. Yesterday [November 22nd] I finished writing up my new objection and sent that in. And, gee, after more than 24 hours it still hasn’t appeared… Presumably the chairs “forgot” to flip the censorship button off after 30 days.
Thanks to alanw (Slashdot reader #1,822) for spotting the blog posts.
“Three years ago, Google removed JPEG XL support from Chrome, stating there wasn’t enough interest at the time,” writes the blog Windows Report. “That position has now changed.”
In a recent note to developers, a Chrome team representative confirmed that work has restarted to bring JPEG XL to Chromium and said Google “would ship it in Chrome” once long-term maintenance and the usual launch requirements are met.
The team explained that other platforms moved ahead. Safari supports JPEG XL, and Windows 11 users can add native support through an image extension from Microsoft Store. The format is also confirmed for use in PDF documents. There has been continuous demand from developers and users who ask for its return.
Before Google ships the feature in Chrome, the company wants the integration to be secure and supported over time. A developer has submitted new code that reintroduces JPEG XL to Chromium. This version is marked as feature complete. The developer said it also “includes animation support,” which earlier implementations did not offer.
“Fresh from announcing it is building an AI browsing mode in Firefox and laying the groundwork for agentic interactions in the Firefox 145 release, the corp arm of Mozilla is now flexing its AI muscles in the direction of those more likely to care,” writes the blog OMG Ubuntu:
If you’re a developer building AI agents, you can sign up to get early access to Mozilla’s TABS API, a “powerful web content extraction and transformation toolkit designed specifically for AI agent builders”… The TABS API enables devs to create agents to automate web interactions, like clicking, scrolling, searching, and submitting forms “just like a human”. Real-time feedback and adaptive behaviours will, Mozilla say, offer “full control of the web, without the complexity.”
As TABS is not powered by a Mozilla-backed LLM you’ll need to connect it to your choice of third-party LLM for any relevant processing… Developers get 1,000 requests monthly on the free tier, which seems reasonable for prototyping personal projects. Complex agentic workloads may require more. Though pricing is yet to be locked in, the TABS API website suggests it’ll cost ~$5 per 1000 requests.
Paid plans will offer additional features too, like lower latency and, somewhat ironically, CAPTCHA solving so AI can ‘prove’ it’s not a robot on pages gated to prevent automated activities.
Google, OpenAI, and other major AI vendors offer their own agentic APIs. Mozilla is pitching up late, but it plans to play differently. It touts a “strong focus on data minimisation and security”, with scraped data treated ephemerally — i.e., not kept. As a distinction, that matters. AI agents can be given complex online tasks that involve all sorts of personal or sensitive data being fetched and worked with…. If you’re minded to make one, perhaps without a motivation to asset-strip the common good, Mozilla’s TABS API look like a solid place to start.
Social media is an overwhelming part of our lives these days, but the Pew Research Center provided an in-depth look at just how much we rely on these platforms. In a 2025 report that looks at social media usage with American adults, the data-driven think tank revealed some nitty-gritty details like year-to-year changes, age gaps and most importantly, frequency of use.
At the number one spot, YouTube holds a dominant position, with 84 percent of the 5,022 adults surveyed saying they use Alphabet’s video-sharing platform. Meta earns silver and bronze medals since 71 percent of adults said they use Facebook, while 50 percent responded positively when it comes to Instagram use. However, not all of Meta’s social media outlets are doing well. Threads may have hit 400 million monthly active users this summer, but only eight percent of adults surveyed said they use it. Rounding out the bottom of the list, only 21 percent of adults surveyed said they use X, while four percent of adults said they’re on Bluesky and three percent are on Truth Social.
Besides popularity, the Pew Research Center also explored the frequency with which American adults use their preferred social media platforms. In a separate survey with 5,123 adults, the report uncovered that 52 percent of adults go on Facebook daily, with 37 percent of them logging on several times a day. Nearly as frequently, 48 percent of adults use YouTube daily, including 33 percent of that demographic watching videos on the platform several times a day. When looking at frequency through the lens of age gaps, the starkest difference is found with 47 percent of adults between 18 and 29 using TikTok at least once a day, while only five percent of those aged 65 or older use the ByteDance-owned app every day.
When looking at annual trends, YouTube and Facebook have largely maintained stable usage — and even some growth — since 2021. Even though it may feel like Facebook has begun to stagnate, the report shows that it has a loyal user base that’s still growing at a consistent rate. On top of that, Meta is still continuing to update the social media platform, including recently revamping Facebook Marketplace.

Long-time Slashdot reader jenningsthecat shared this article from IEEE Spectrum:
By dropping a nuclear reactor 1.6 kilometers (1 mile) underground, Deep Fission aims to use the weight of a billion tons of rock and water as a natural containment system comparable to concrete domes and cooling towers. With the fission reaction occurring far below the surface, steam can safely circulate in a closed loop to generate power.
The California-based startup announced in October that prospective customers had signed non-binding letters of intent for 12.5 gigawatts of power involving data center developers, industrial parks, and other (mostly undisclosed) strategic partners, with initial sites under consideration in Kansas, Texas, and Utah… The company says its modular approach allows multiple 15-megawatt reactors to be clustered on a single site: A block of 10 would total 150 MW, and Deep Fission claims that larger groupings could scale to 1.5 GW. Deep Fission claims that using geological depth as containment could make nuclear energy cheaper, safer, and deployable in months at a fraction of a conventional plant’s footprint…
The company aims to finalize its reactor design and confirm the pilot site in the coming months. [Company founder Liz] Muller says the plan is to drill the borehole, lower the canister, load the fuel, and bring the reactor to criticality underground in 2026. Sites in Utah, Texas, and Kansas are among the leading candidates for the first commercial-scale projects, which could begin construction in 2027 or 2028, depending on the speed of DOE and NRC approvals. Deep Fission expects to start manufacturing components for the first unit in 2026 and does not anticipate major bottlenecks aside from typical long-lead items.
In short “The same oil and gas drilling techniques that reliably reach kilometer-deep wells can be adapted to host nuclear reactors…” the article points out. Their design would also streamline construction, since “Locating the reactors under a deep water column subjects them to roughly 160 atmospheres of pressure — the same conditions maintained inside a conventional nuclear reactor — which forms a natural seal to keep any radioactive coolant or steam contained at depth, preventing leaks from reaching the surface.”
Other interesting points from the article:
They plan on operating and controlling the reactor remotely from the surface.
Company founder Muller says if an earthquake ever disrupted the site, “you seal it off at the bottom of the borehole, plug up the borehole, and you have your waste in safe disposal.”
For waste management, the company “is eyeing deep geological disposal in the very borehole systems they deploy for their reactors.”
“The company claims it can cut overall costs by 70 to 80 percent compared with full-scale nuclear plants.”
“Among its competition are projects like TerraPower’s Natrium, notes
the tech news site Hackaday, saying TerraPower’s fast neutron reactors “are already under construction and offer much more power per reactor, along with Natrium in particular also providing built-in grid-level storage.
“One thing is definitely for certain…” they add. “The commercial power sector in the US has stopped being mind-numbingly boring.”
In a recent interview, Valve warned that the upcoming Steam Machine won’t be priced like a game console. It’s not clear what that means just yet, but speculation concerning the Steam Machine’s pricing has been rampant. We previously wrote up a defense of the Steam Machine’s mid-range PC specifications, but GPU performance roughly on par with
In a rare event, a number of first-party Nintendo Switch games are on sale on Amazon, just in time for Black Friday. While Nintendo doesn’t often place any of its first-party titles on sale, a number of prominent games including Super Mario Odyssey, The Legend of Zelda: Echoes of Wisdom, and Donkey Kong Country Returns HD are up to 50% off.
Valve shook up the gaming world with the announcement of the Steam Machine, but we’re all still curious about the million-dollar question of pricing. While there’s plenty of speculation, we finally have some sort of indication from Valve directly. In an interview with Skill Up’s Friends Per Second podcast, Valve’s Pierre-Loup Griffais revealed that the Steam Machine will not be subsidized but will still have competitive pricing.
“I think that if you build a PC from parts and get to basically the same level of performance, that’s the general price window that we aim to be at,” Griffais said on the podcast. “Obviously, our goal is for it to be a good deal at that level of performance, and then you have features that are actually really hard to build if you’re making your own gaming PC from parts.”
Griffais didn’t offer a concrete price range since Valve was still early in the process, adding that “right now is just a hard time to have a really good idea of what the price is going to be because there’s a lot of different things that are fluctuating.” When asked if the Steam Machine would be subsidized like how other companies often sell new consoles at a loss or slim profit margin to generate early momentum, Griffais said no and that it would be “more in line with what you might expect from the current PC market.”
However, Griffais also revealed that Valve is potentially interested in doing a Steam Machine Pro, but that the company is currently focused on this mid-range level as a “good trade off between affordability and the level of power we get.”
