During today's Nvidia GTC keynote, the company introduced NemoClaw, a security-focused stack designed to make the autonomous AI agent platform OpenClaw safer. ZDNet explains how it works: NemoClaw installs Nvidia's OpenShell, a new open-source runtime that keeps agents safer to use by enforcing an organization's policy-based guardrails. OpenShell keeps models sandboxed, adds data privacy protections and additional security for agents, and makes them more scalable. "This provides the missing infrastructure layer beneath claws to give them the access they need to be productive, while enforcing policy-based security, network, and privacy guardrails," Nvidia said in the announcement. The company built OpenShell with security companies like CrowdStrike, Cisco, and Microsoft Security to ensure it is compatible with other cybersecurity tools.

Nvidia said NemoClaw can be installed in a single command, runs on any platform, and can use any coding agent, including Nvidia's own Nemotron open model family, on a local system. Through a privacy router, it allows agents to access frontier models in the cloud, which unites local and cloud models to help teach agents how to complete tasks within privacy guardrails, Nvidia explained. Nvidia seems to be hoping that the additional security can make OpenClaw agents more popular and accessible, with less risk than they currently carry. The bigger picture here is how NemoClaw could give companies the added peace of mind to let AI agents complete actions for their employees, where they wouldn't have previously. Nvidia did not specify when NemoClaw would be available.

Nuclear engineer Lonnie Johnson worked on NASA's Galileo mission, has more than 140 patents, and invented the Super Soaker water gun. But now he's working on "a potential key to unlock a huge power source that's rarely utilized today," reports the Atlanta Journal-Constitution. [Alternate URL here.]

Waste heat... The Johnson Thermo-Electrochemical Converter, or JTEC, has few moving parts, no combustion and no exhaust. All the work to generate electricity is done by hydrogen, the most abundant element in the universe. Inside the device, pressurized hydrogen gas is separated by a thin, filmlike membrane, with low pressure gas on one side and high pressure gas on the other. The difference in pressure in this "stack" is what drives the hydrogen to compress and expand, creating electricity as it circulates. And unlike a fuel cell, it does not need to be refueled with more hydrogen. All that's needed to keep the process going and electricity flowing is a heat source.

As it turns out, there are enormous amounts of energy vented or otherwise lost from industrial facilities like power plants, factories, breweries and more. Between 20% and 50% of all energy used for industrial processes is dumped into the atmosphere and lost as waste heat, according to the U.S. Department of Energy. The JTEC works with high temperatures, but the device's ability to generate electricity efficiently from low-grade heat sources is what company executives are most excited about. Inside JTEC's headquarters, engineers show off a demonstration unit that can power lights and a sound system with water that's roughly 200 degrees Fahrenheit — below the boiling point and barely warm enough to brew a cup of tea, said Julian Bell, JTEC's vice president of engineering. Comas Haynes, a research engineer at the Georgia Tech Research Institute specializing in thermal and hydrogen system designs, agrees the company could "hit a sweet spot" if it can capitalize on lower temperature heat...

For Johnson, the potential application he's most excited about lies beneath our feet. Geothermal energy exists naturally in rocks and water beneath the Earth's surface at various depths. Tapping into that resource through abandoned oil and gas wells — a well-known access point for underground heat — offers another opportunity. "You don't need batteries and you can draw power when you need it from just about anywhere," Johnson said. Right now, the company is building its first commercial JTEC unit, which is set to be deployed early next year. Mike McQuary, JTEC's CEO and the former president of the pioneering internet service provider MindSpring, said he couldn't reveal the customer, but said it's a "major Southeast utility company." "Crossing that bridge where you have commercial customers that believe in it and will pay for it is important," McQuary said...

On top of some initial seed money, the company brought in $30 million in a Series A funding in 2022 — money that allowed the company to move to its Lee + White headquarters and hire more than 30 engineers. McQuary said it expects to begin another round of fundraising soon.
"Johnson, meanwhile, hasn't stopped working on new inventions," the article points out. "He continues to refine the design for his solid-state battery..."

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.

A promotional video for Amazon's Kiro software development system took a unique approach, writes GeekWire. "Instead of product diagrams or keynote slides, a crew from Seattle's Packrat creative studio used action figures on a miniature set to create a stop-motion sequence..."

"Can the software development hero conquer the 'AI Slop Monster' to uncover the gleaming, fully functional robot buried beneath the coding chaos?" Kiro (pronounced KEE-ro) is Amazon's effort to rethink how developers use AI. It's an integrated development environment that attempts to tame the wild world of vibe coding... But rather than simply generating code from prompts [in "vibe mode"], Kiro breaks down requests into formal specifications, design documents, and task lists [in "spec mode"]. This spec-driven development approach aims to solve a fundamental problem with vibe coding: AI can quickly generate prototypes, but without structure or documentation, that code becomes unmaintainable...

The market for AI-powered development tools is booming. Gartner expects AI code assistants to become ubiquitous, forecasting that 90% of enterprise software engineers will use them by 2028, up from less than 14% in early 2024... Amazon launched Kiro in preview in July, to a strong response. Positive early reviews were tempered by frustration from users unable to gain access. Capacity constraints have since been resolved, and Amazon says more than 250,000 developers used Kiro in the first three months...

Now, the company is taking Kiro out of preview into general availability, rolling out new features and opening the tool more broadly to development teams and companies... During the preview period, Kiro handled more than 300 million requests and processed trillions of tokens as developers explored its capabilities, according to stats provided by the company. Rackspace used Kiro to complete what they estimated as 52 weeks of software modernization in three weeks, according to Amazon executives. SmugMug and Flickr are among other companies espousing the virtues of Kiro's spec-driven development approach. Early users are posting in glowing terms about the efficiencies they're seeing from adopting the tool... startups in most countries can apply for up to 100 free Pro+ seats for a year's worth of Kiro credits.
Kiro offers property-based testing "to verify that generated code actually does what developers specified," according to the article — plus a checkpointing system that "lets developers roll back changes or retrace an agent's steps when an idea goes sideways..."

"And yes, they've been using Kiro to build Kiro, which has allowed them to move much faster."

"AI isn't just a tool anymore; it's an integral part of the development experience," argues GitHub's blog. So "Agents shouldn't be bolted on. They should work the way you already work..."

So this week GitHub announced "Agent HQ," which CNBC describes as a "mission control" interface "that will allow software developers to manage coding agents from multiple vendors on a single platform." Developers have a range of new capabilities at their fingertips because of these agents, but it can require a lot of effort to keep track of them all individually, said GitHub COO Kyle Daigle. Developers will now be able to manage agents from GitHub, OpenAI, Google, Anthropic, xAI and Cognition in one place with Agent HQ. "We want to bring a little bit of order to the chaos of innovation," Daigle told CNBC in an interview. "With so many different agents, there's so many different ways of kicking off these asynchronous tasks, and so our big opportunity here is to bring this all together." Agent HQ users will be able to access a command center where they can assign, steer and monitor the work of multiple agents...

The third-party agents will begin rolling out to GitHub Copilot subscribers in the coming months, but Copilot Pro+ users will be able to access OpenAI Codex in VS Code Insiders this week, the company said.
"We're into this wave two era," GitHub's COO Mario Rodriguez told VentureBeat, an era that's "going to be multimodal, it's going to be agentic and it's going to have these new experiences that will feel AI native...."

Or, as VentureBeat sees it, GitHub "is positioning itself as the essential orchestration layer beneath them all..." Just as the company transformed Git, pull requests and CI/CD into collaborative workflows, it's now trying to do the same with a fragmented AI coding landscape...

The technical architecture addresses a critical enterprise concern: Security. Unlike standalone agent implementations where users must grant broad repository access, GitHub's Agent HQ implements granular controls at the platform level... Agents operating through Agent HQ can only commit to designated branches. They run within sandboxed GitHub Actions environments with firewall protections. They operate under strict identity controls. [GitHub COO] Rodriguez explained that even if an agent goes rogue, the firewall prevents it from accessing external networks or exfiltrating data unless those protections are explicitly disabled.

Beyond managing third-party agents, GitHub is introducing two technical capabilities that set Agent HQ apart from alternative approaches like Cursor's standalone editor or Anthropic's Claude integration. Custom agents via AGENTS.md files: Enterprises can now create source-controlled configuration files that define specific rules, tools and guardrails for how Copilot behaves. For example, a company could specify "prefer this logger" or "use table-driven tests for all handlers." This permanently encodes organizational standards without requiring developers to re-prompt every time... Native Model Context Protocol (MCP) support: VS Code now includes a GitHub MCP Registry. Developers can discover, install and enable MCP servers with a single click. They can then create custom agents that combine these tools with specific system prompts. This positions GitHub as the integration point between the emerging MCP ecosystem and actual developer workflows. MCP, introduced by Anthropic but rapidly gaining industry support, is becoming a de facto standard for agent-to-tool communication. By supporting the full specification, GitHub can orchestrate agents that need access to external services without each agent implementing its own integration logic.

GitHub is also shipping new capabilities within VS Code itself. Plan Mode allows developers to collaborate with Copilot on building step-by-step project approaches. The AI asks clarifying questions before any code is written. Once approved, the plan can be executed either locally in VS Code or by cloud-based agents. The feature addresses a common failure mode in AI coding: Beginning implementation before requirements are fully understood. By forcing an explicit planning phase, GitHub aims to reduce wasted effort and improve output quality.

More significantly, GitHub's code review feature is becoming agentic. The new implementation will use GitHub's CodeQL engine, which previously largely focused on security vulnerabilities to identify bugs and maintainability issues. The code review agent will automatically scan agent-generated pull requests before human review. This creates a two-stage quality gate.
"Don't let this little bit of news float past you like all those self-satisfied marketing pitches we semi-hear and ignore," writes ZDNet: If it works and remains reliable, this is actually a very big deal... Tech companies, especially the giant ones, often like to talk "open" but then do their level best to engineer lock-in to their solution and their solution alone. Sure, most of them offer some sort of export tool, but the barrier to moving from one tool to another is often huge... [T]he idea that you can continue to use your favorite agent or agents in GitHub, fully integrated into the GitHub tool path, is powerful. It means there's a chance developers might not have to suffer the walled garden effect that so many companies have strived for to lock in their customers.

A first-of-its-kind global research expedition has extracted freshwater samples from beneath the Atlantic Ocean floor off Cape Cod, documenting a massive aquifer stretching from New Jersey to Maine. The three-month Expedition 501, funded at $25 million by the National Science Foundation and European Consortium for Ocean Research Drilling, drilled up to 1,289 feet into the seabed at sites 20-30 miles offshore.

Samples registered salinity as low as 1 part per thousand -- meeting U.S. freshwater standards -- with some readings even lower. Scientists collected nearly 50,000 liters for laboratory analysis to determine whether the water originates from ancient glacial melt or current terrestrial groundwater systems. The UN projects global freshwater demand will exceed supply by 40% within five years.

Liquefied CO2 will be transported by ship to "the world's first carbon shipping port," reports the Washington Post — an island in the North Sea where it will be "buried in a layer of spongy rock a mile and a half beneath the seabed."

Norway's government is covering 80% of the $1 billion first phase, with another $714 million from three fossil fuel companies toward an ongoing expansion (with an additional $150 million E.U. subsidy). As Europe's top oil and gas producer, Norway is using its fossil fuel income to see if they can make "carbon dumping" work. The world's first carbon shipment arrived this summer, carrying 7,500 metric tons of liquefied CO2 from a Norwegian cement factory that otherwise would have gone into the atmosphere... If all goes as planned, the project's backers — Shell, Equinor and TotalEnergies, along with Norway — say their facility could pump 5 million metric tons of carbon dioxide underground each year, or about a tenth of Norway's annual emissions...

[At the Heidelberg Materials cement factory in Brevik, Norway], when hot CO2-laden air comes rushing out of the cement kilns, the plant uses seawater from the neighboring fjord to cool it down. The cool air goes into a chamber where it gets sprayed with amine, a chemical that latches onto CO2 at low temperatures. The amine mist settles to the bottom, dragging carbon dioxide down with it. The rest of the air floats out of the smokestack with about 85 percent less CO2 in it, according to project manager Anders Pettersen. Later, Heidelberg Materials uses waste heat from the kilns to break the chemical bonds, so that the amine releases the carbon dioxide. The pure CO2 then goes into a compressor that resembles a giant steel heart, where it gets denser and colder until it finally becomes liquid. That liquid CO2 remains in storage tanks until a ship comes to carry it away. At best, operators expect this system to capture half the plant's CO2 emissions: 400,000 metric tons per year, or the equivalent of about 93,000 cars on the road...

[T]hree other companies are lined up to follow: Ørsted, which will send CO2 from two bioenergy plants in Denmark; Yara, which will send carbon from a Dutch fertilizer factory; and Stockholm Exergi, which will capture carbon from a Swedish bioenergy plant that burns wood waste. All of these projects have gotten significant subsidies from national governments and the European Union — essentially de-risking the experiment for the companies. Experts say the costs and headaches of installing and running carbon-capture equipment may start to make more financial sense as European carbon rules get stricter and the cost of emitting a ton of carbon dioxide goes up. Still, they say, it's hard to imagine many companies deciding to invest in carbon capture without serious subsidies...

The first shipments are being transported by Northern Pioneer, the world's biggest carbon dioxide tanker ship, built specifically for this project. The 430-foot ship can hold 7,500 metric tons of CO2 in tanks below deck. Those tanks keep it in a liquid state by cooling it to minus-15 degrees Fahrenheit and squeezing it with the same pressure the outside of a submarine would feel 500 feet below the waves. While that may sound extreme, consider that the liquid natural gas the ship uses for fuel has to be stored at minus-260 degrees. "CO2 isn't difficult to make it into a liquid," said Sally Benson, professor of energy science and engineering at Stanford University. Northern Pioneer is designed to emit about a third less carbon dioxide than a regular ship — key for a project that aims to eliminate carbon emissions. The ship burns natural gas, which emits less CO2 than marine diesel produces (though gas extraction is associated with methane leaks). The vessel uses a rotor sail to capture wind power. And it blows a constant stream of air bubbles to reduce friction as the hull cuts through the water, allowing it to burn less fuel. For every 100 tons of CO2 that Northern Lights pumps underground, it expects to emit three tons of CO2 into the atmosphere, mainly by burning fuel for shipping.
Eventually the carbon flows into a pipeline "that plunges through the North Sea and into the rocky layers below it — an engineering feat that's a bit like drilling for oil in reverse..." according to the article.

"Over the centuries, it should chemically react with the rock, eventually being locked away in minerals."

Microsoft is positioning Windows as the primary gaming platform for Xbox, according to Xbox president Sarah Bond. "We're working closely with the Windows team to ensure that Windows is the number one platform for gaming," Bond said in a video announcing a partnership with AMD for next-generation Xbox hardware spanning consoles and handhelds.

The statement, PCWorld points out, aligns with Microsoft's recent "This is an Xbox" marketing campaign, which promotes phones, PCs, televisions, and traditional consoles as Xbox devices. The company's newly announced Xbox Ally X handheld runs Windows beneath its Xbox interface, allowing access to multiple game stores unlike Valve's Steam Deck.

Microsoft has shifted strategy following weak Xbox console sales compared to PlayStation, spending billions to acquire publishers including Bethesda and Activision Blizzard while expanding Xbox Cloud Gaming services across multiple device types.

Evidence is mounting for "a vast reservoir of liquid water" on Mars, according to a new article by Australian National University professor Hrvoje TkalÄiÄ and geophysics associate professor Weijia Sun from the Chinese Academy of Geological Sciences, announcing their recently published paper.

"Using seismic data from NASA's InSight mission, we uncovered evidence that the seismic waves slow down in a layer between 5.4 and 8 kilometres below the surface, which could be because of the presence of liquid water at these depths." Mars is covered in traces of ancient bodies of water. But the puzzle of exactly where it all went when the planet turned cold and dry has long intrigued scientists... Billions of years ago, during the Noachian and Hesperian periods (4.1 billion to 3 billion years ago), rivers carved valleys and lakes shimmered. As Mars' magnetic field faded and its atmosphere thinned, most surface water vanished. Some escaped to space, some froze in polar caps, and some was trapped in minerals, where it remains today. But evaporation, freezing and rocks can't quite account for all the water that must have covered Mars in the distant past.

Calculations suggest the "missing" water is enough to cover the planet in an ocean at least 700 metres deep, and perhaps up to 900 metres deep. One hypothesis has been that the missing water seeped into the crust. Mars was heavily bombarded by meteorites during the Noachian period, which may have formed fractures that channelled water underground. Deep beneath the surface, warmer temperatures would keep the water in a liquid state — unlike the frozen layers nearer the surface.

In 2018, NASA's InSight lander touched down on Mars to listen to the planet's interior with a super-sensitive seismometer. By studying a particular kind of vibration called "shear waves", we found a significant underground anomaly: a layer between 5.4 and 8 kilometres down where these vibrations move more slowly. This "low-velocity layer" is most likely highly porous rock filled with liquid water, like a saturated sponge. Something like Earth's aquifers, where groundwater seeps into rock pores. We calculated the "aquifer layer" on Mars could hold enough water to cover the planet in a global ocean 520-780m deep.
InSight's seismometer captured vibrations between the crust of Mars and its lower layers from two meteorite impacts in 2021 and a Marsquake in 2022. "These signatures let us pinpoint boundaries where rock changes, revealing the water-soaked layer 5.4 to 8 kilometres deep."

It's an exciting possibility. "Purified, it could provide drinking water, oxygen, or fuel for rockets." And since microbes thrives on earth in deep rocks filled with water, "Could similar life, perhaps relics of ancient Martian ecosystems, persist in these reservoirs?"

Earth's core "burns with an estimated forty-four trillion watts of power," the New Yorker reminds us — enough to "satisfy the entire world's energy needs" with a power source that's carbon-free, ubiquitous — and unlimited. (Besides running 24 hours a day, one of geothermal energy's key advantages is "it can be used for both electricity and heating, which collectively account for around 38% of global climate emissions...")

And one drilling expert tells them there's been an "exponential spin-up of activity in geothermal" energy projects over the last two years. (Ironically it was the fracking boom also brought an "explosion of new drilling practices — such as horizontal drilling and magnetic sensing — that inspired a geothermal resurgence.") In 2005 one research team calculated that just 2% of the heat just four miles underground in America "could meet the entire country's energy needs — two thousand times over," according to the article.

So their new article checks in on the progress of geothermal energy projects around the world, including a Utah company using a diamond-bit drill to dig nearly a mile into the earth to install a 150-ton steel tube surrounded by special heat-resistant cement — all to create "a massive straw" for transporting hot water (and steam). The biggest problem is drilling miles through hot rock, safely. If scientists can do that, however, next-generation geothermal power could supply clean energy for eons... At 6:15 P.M. on May 3rd, cement had started flowing into the hole. Four hours later, part of the cement folded in on itself. The next morning, the cement supply ran out; the men had miscalculated how much they needed. This brought the three-hundred-million-dollar operation to a maddening halt... The cement truck from Bakersfield arrived around 8:30 P.M. By ten-thirty, the men were pouring cement again, gluing the enormous metal straw in place. Next, the team scanned the borehole with gamma rays...

A new study suggests Uranus' moon Miranda may harbor a vast subsurface ocean, challenging previous assumptions about its frozen state and positioning it as a potential ocean world alongside other icy moons. Phys.Org reports: Among the moons in the solar system, Miranda stands out. The few images Voyager 2 captured in 1986 show Miranda's southern hemisphere (the only part we've seen) is a Frankenstein-like hodgepodge of grooved terrain quartered off by rough scarps and cratered areas, like squares on a quilt. Most researchers suspect these bizarre structures are the result of tidal forces and heating within the moon. Caleb Strom, a graduate student at the University of North Dakota who worked with Nordheim and Alex Patthoff of the Planetary Science Institute in Arizona, revisited the Voyager 2 images. The team set out to explain Miranda's enigmatic geology by reverse engineering the surface features, working backward to uncover what the moon's interior structure must have been to shape the moon's geology in response to tidal forcing.

After first mapping the various surface features like cracks, ridges and Miranda's unique trapezoidal coronae, the team developed a computer model to test several possible structures of the moon's interior, matching the predicted stress patterns to the actual surface geology. The setup that produced the best match between predicted stress patterns and observed surface features required the existence of vast ocean beneath Miranda's icy surface some 100-500 million years ago. This subsurface ocean was at least 62 miles (100 kilometers) deep, according to the study, and hidden beneath an icy crust no more than 19 miles (30 kilometers) thick. Given Miranda has a radius of just 146 miles (235 kilometers), the ocean would have filled almost half of the moon's body. "That result was a big surprise to the team," Strom said.

Key to creating that ocean, the researchers believe, were tidal forces between Miranda and nearby moons. These regular gravitational tugs can be amplified by orbital resonances -- a configuration where each moon's period around a planet is an exact integer of the others' periods. Jupiter's moons Io and Europa, for example, have a 2:1 resonance: For every two orbits Io makes around Jupiter, Europa makes exactly one, leading to tidal forces that are known to sustain an ocean beneath Europa's surface. These orbital configurations and the resulting tidal forces deform the moons like rubber balls, leading to friction and heat that keeps interiors warm. This also creates stresses that crack the surface, creating a rich tapestry of geologic features. Numerical simulations have suggested that Miranda and its neighboring moons likely had such a resonance in the past, offering a potential mechanism that could have warmed Miranda's interior to produce and maintain a subsurface ocean.

At some point, the moons' orbital ballet desynchronized, slowing the heating process so that the moon's insides started to cool and solidify. But the team doesn't think Miranda's interior has fully frozen yet. If the ocean had completely frozen, Nordheim explained, it would have expanded and caused certain telltale cracks on the surface, which aren't there. This suggests that Miranda is still cooling -- and may have an ocean beneath its surface even now. Miranda's modern-day ocean is probably relatively thin, Strom noted. "But the suggestion of an ocean inside one of the most distant moons in the solar system is remarkable," he said. Miranda wasn't predicted to have an ocean. With its small size and old age, scientists thought it would likely be a frozen ball of ice. Any leftover heat from its formation was assumed to have dissipated long ago. But as Patthoff pointed out, predictions about ice moons can be wrong, as evidenced by Saturn's moon Enceladus. The study has been published in The Planetary Science Journal.

SFGate spills the secrets of Disneyland's "Enchanted Tiki Room" and its lifelike animatronic singing birds — Jose, Fritz, Michael and Pierre — "whose movements were perfectly synced with the audio track." "Beneath the room, the heartbeat of the attraction is a $1 million installation of electronics equipment, operated by a roll of 14-channel magnetic tape," the Orange County Register wrote upon its opening. "It is the same system which programs the U.S. military's polaris missile." That system also ran very hot. To keep guests from overheating, air conditioning was installed throughout the building, making the Tiki Room Disneyland's first attraction to be fully air conditioned...
Or, as another article puts it, "While Disney did not delve into the speculative science of cryogenics to preserve his life, he did borrow the mechanical brain of a nuclear missile to simulate life, creating a new type of entertainment in the process."

The article remembers how Wernher Von Braun became a technical advisor (and on-camera presenter) for three Disney-produced TV episodes about space travel — at the same time Von Braun was working as technical director for the U.S. Army rocket program that produced the world's first long-range guided ballistic missile, plus the first submarine-launched ballistic missile with its ground-breaking launch control mechanism: An important aspect of the Polaris launch system hinged on the fact that the conditions under which the missiles might be launched were constantly changing. Different underwater currents, temperatures, and flexing of the metal hull all contributed to the difficulty of a successful launch. In order to minimize human errors and to automate the sequence as much as possible, scientists developed an audio control system. A magnetic audio tape with a series of prerecorded cues precisely timed to account for the submarine's movement, controlled the launch machinery.

This new technology, invented to deliver nuclear destruction, proved exactly what Disney needed for his wonderland developed for children.
The article concludes that Disneyland engineering "transformed Von Braun's military technology" to the point today where "what was once controlled by the artificial brain of a nuclear missile is now run by the equivalent of a MacBook."

SFGate delves deeper into the attraction's strange origins — and how it all came full circle 63 years later... At the intersection of Main Street and Adventureland, a restaurant called the Pavillion — now the Jolly Holiday — bridged the gap. Under one roof, it served food to Main Street guests on one side and Adventureland diners on the other. The inelegant transition created an eyesore that Walt despised... The need for the Tiki Cafe "appeared to be less about food and more about aesthetics," Ken Bruce writes in Before the Birds Sang Words , a comprehensive history of the attraction.

In 1961, Walt gathered with park designers about the concept. The sketch made by legendary theme park designer John Hench was remarkably thorough, with much of its design incorporated into the final product... When Walt saw a plethora of birds in the sketch, he famously exclaimed, "We can't have birds in there ... because they'll poop in the food." Hench hurriedly ad-libbed that the birds would be mechanical, a concept that Walt adored...

Although its powerful air conditioning may be its biggest draw today, many attractions you love owe their existence to the flock of singing birds. Disney engineers' work on the talking flora and fauna laid the foundation for much more complex Audio-Animatronics (a word that Walt Disney coined). Without Jose, Fritz, Michael and Pierre, there would be no Haunted Mansion, no Pirates of the Caribbean, no Rise of the Resistance. Next year, in celebration of Disneyland's 70th anniversary, the park will unveil one of its most sophisticated animatronics yet: Walt Disney himself. It will be the first time Walt appears in a Disney attraction anywhere in the world, completing a journey that started with a mechanical bird and ends with an immortal homage.
Their article also reveals that a year after the Tiki Room opened, one of the birds was programmed to say "Come, there's an island there for you in Hawaii. Soaring birds of United Airlines fly there too!" Because Disneyland had signed a sponsorship deal with United Airlines...

Newsweek writes that the missing atmosphere of Mars "may be locked up in the planet's clay-rich surface, a new study by MIT geologists has suggested." According to the researchers, ancient water trickling through Mars' rocks could have triggered a series of chemical reactions, converting CO2 into methane and trapping the carbon in clay minerals for billions of years...

The dominant explanation relies on an interaction between the sun's rays and gases in the atmosphere. Mars lost its protective magnetic field billions of years ago, likely allowing high-energy solar particles to strike the upper atmosphere, kicking molecules off into space, according to NASA... But this might not be the whole story. The researchers focused on a type of clay mineral called smectite, known for its ability to trap carbon. These minerals, abundant on Mars, contain tiny folds that can store carbon molecules for aeons. The study was published in the journal Science Advances.

"There is plenty of evidence for a thick clay layer on the Martian surface. Almost 80 percent of satellite spectra detect these high-surface-area clay minerals on the Martian surface. Clay has been detected in craters as deep as 17 kilometers [10.5 miles]," [lead author Joshua] Murray said... Their model suggested that Mars' surface could contain up to 1.7 bar of CO2 — roughly 80 percent of its early atmospheric volume — sequestered as methane within clay deposits. This methane could still be present today, lying beneath the planet's dry and barren crust. "We know this process happens, and it is well-documented on Earth. And these rocks and clays exist on Mars," Oliver Jagoutz, the study's author, said in a statement. "So, we wanted to try and connect the dots."

The discovery that Mars' ancient atmosphere could be hidden within its surface clays offers a new perspective on the planet's history and raises intriguing possibilities for future exploration. For example, if the sequestered carbon could be recovered and converted, it could serve as a propellant for future space missions between Earth, Mars and beyond.
"In some ways, Mars' missing atmosphere could be hiding in plain sight," says the study's lead author — and the article adds that this raises some interesting possibilities.

"For example, if the sequestered carbon could be recovered and converted, it could serve as a propellant for future space missions between Earth, Mars and beyond..."

"The cab was cut from a 1997 Jeep Grand Cherokee," writes the New York Times. "The engine once revved up a 1985 Toyota Celica; and 107 hand-sewn rubber segments, courtesy of Mr. Tymofichuk's wife, help to direct low-pressure air beneath the craft so that it rises eight inches above the ground..." On a cold spring day in a small garage in Alberta, Canada, an engine revved up and an improbable machine — fabricated from auto parts, a hand-sewn rubber skirt and an abandoned fiberglass hull — came to life.

A homemade hovercraft began to rise off the ground with a small crew standing by.

The successful liftoff was the culmination of a lifelong fascination of Robert Tymofichuk, 55, who spent about 1,800 hours over a year working on it [according to this nifty video on YouTube ]. And, to the gratitude of passengers, it comes with heated seats. "If you're going through all that hassle, you might as well make yourself comfortable," Mr. Tymofichuk said. He repurposed the seats from a Volkswagen, so the heating coils were already installed.
Achieve speeds around 40 miles per hour (or 64 kmph), "Mr. Tymofichuk's hovercraft now sails above land and water, a bright red gem coasting over the Saskatchewan River," according to the article. And it also quotes Mr. Tymofichuk as saying it's the fulfillment of a childhood dream.

"To actually have something constructed with your own hands be zipping around, and it's fully functional — it's like magic."

"Slabs of material from an ancient extraterrestrial planet are hidden deep within the Earth," argues a new scientific theory (as described by CNN).

"Scientists widely agree that an ancient planet likely smashed into Earth as it was forming billions of years ago, spewing debris that coalesced into the moon that decorates our night sky today." But then whatever happened to that planet? No leftover fragments from a hypothetical planet "Theia" have ever been found in our solar system.

But the new theory "suggests that remnants of the ancient planet remain partially intact, buried beneath our feet." If the theory is correct, it would not only provide additional details to fill out the giant-impact hypothesis but also answer a lingering question for geophysicists. They were already aware that there are two massive, distinct blobs that are embedded deep within the Earth. The masses — called large low-velocity provinces, or LLVPs — were first detected in the 1980s. One lies beneath Africa and another below the Pacific Ocean.
The study's lead author (Dr. Qian Yuan, a geophysicist and postdoctoral fellow at the California Institute of Technology) first proposed the idea for a paper three times in 2021 — and was rejected each time. But "then he came across scientists who did just the type of research Yuan needed." Their work, which assigned a certain size to Theia and speed of impact in the modeling, suggested that the ancient planet's collision likely did not entirely melt Earth's mantle, allowing the remnants of Theia to cool and form solid structures instead of blending together in Earth's inner stew... If Theia were a certain size and consistency, and struck the Earth at a specific speed, the models showed it could, in fact, leave behind massive hunks of its guts within Earth's mantle and also spawn the debris that would go on to create our moon...

The study Yuan published this week includes coauthors from a variety of disciplines across a range of institutions, including Arizona State, Caltech, the Shanghai Astronomical Observatory and NASA's Ames Research Center.

In downtown San Francisco two vehicles were stopped at a red light on Monday night, reports the Washington Post — a regular car and a Cruise robotaxi. Both vehicles advanced when the light turned green, according to witness accounts and video recorded by the Cruise vehicle's internal cameras and reviewed by The Post. As the cars moved forward, the pedestrian entered the traffic lanes in front of them, according to the video, and was struck by the regular car. The video shows the victim rolling onto that vehicle's windshield and then being flung into the path of the driverless car, which stopped once it collided with the woman. According to Cruise spokesperson Hannah Lindow, the autonomous vehicle "braked aggressively to minimize the impact" but was unable to stop before rolling over the woman and coming to a halt. Photos published by the San Francisco Chronicle show the woman's leg sticking out from underneath the car's left rear wheel.
"According to Cruise, police had directed the company to keep the vehicle stationary, apparently with the pedestrian stuck beneath it," reports the San Francisco Chronicle.

Also from the San Francisco Chronicle: Austin Tutone, a bicycle delivery person, saw the woman trapped underneath the Cruise car and tried to reassure her as they waited for first-responders. "I told her, 'The ambulance is coming' and that she'd be okay. She was just screaming." He shared a photo of the aftermath with The Chronicle that appears to show the car tire on the woman's leg. San Francisco firefighters arrived and used the jaws of life to lift the car off the woman. She was transported to San Francisco General Hospital with "multiple traumatic injuries," said SFFD Capt. Justin Schorr. The victim was in critical condition as of late Tuesday afternoon, according to the hospital.

It appears that once the Cruise car sensed something underneath its rear axle, it came to a halt and turned on its hazard lights, Schorr said. Firefighters obstructed the sensors of the driverless car to alert the Cruise control center. He said representatives from Cruise responded to firefighters and "immediately disabled the car remotely." More from the San Francisco Chronicle: "When it comes to someone pinned beneath a vehicle, the most effective way to unpin them is to lift the vehicle," Sgt. Kathryn Winters, a spokesperson for the department, said in an interview. Were a driver to move a vehicle with a person lying there, "you run the risk of causing more injury." Once the person is freed, the car must stay in place as police gather evidence including "the location of the vehicle and/or vehicles before, during and after the collision," said Officer Eve Laokwansathitaya, another spokesperson.
The human driver who struck the pedestrian immediately fled the scene, and has not yet been identified.

Vanity Fair revisits the many warning signs about OceanGate's Titan submersible prior to an implosion on June 18th that killed all five passengers onboard.

A professional expedition leader tells their reporter that "This tragedy was predicted. It was avoidable. It was inevitable." As the world now knows, Stockton Rush touted himself as a maverick, a disrupter, a breaker of rules. So far out on the visionary curve that, for him, safety regulations were mere suggestions. "If you're not breaking things, you're not innovating," he declared at the 2022 GeekWire Summit. "If you're operating within a known environment, as most submersible manufacturers do, they don't break things. To me, the more stuff you've broken, the more innovative you've been." In a culture that has adopted the ridiculous mantra "move fast and break things," that type of arrogance can get a person far. But in the deep ocean, the price of admission is humility — and it's nonnegotiable...

In December 2015, two years before the Titan was built, Rush had lowered a one third scale model of his 4,000-meter-sub-to-be into a pressure chamber and watched it implode at 4,000 psi, a pressure equivalent to only 2,740 meters. The test's stated goal was to "validate that the pressure vessel design is capable of withstanding an external pressure of 6,000 psi — corresponding to...a depth of about 4,200 meters." He might have changed course then, stood back for a moment and reconsidered. But he didn't. Instead, OceanGate issued a press release stating that the test had been a resounding success because it "demonstrates that the benefits of carbon fiber are real."
OceanGate's director of marine operations later issued a Quality Control Inspection Report filled with warnings: These included missing bolts and improperly secured batteries, components zip-tied to the outside of the sub. O-ring grooves were machined incorrectly (which could allow water ingress), seals were loose, a highly flammable, petroleum-based material lined the Titan's interior... Yet even those deficiencies paled in comparison to what Lochridge observed on the hull. The carbon fiber filament was visibly coming apart, riddled with air gaps, delaminations, and Swiss cheese holes — and there was no way to fix that short of tossing the hull in a dumpster...

Rush's response was to fire Lochridge immediately, serve him and his wife with a lawsuit (although Carole Lochridge didn't work at OceanGate or even in the submersible industry) for breach of contract, fraud, unjust enrichment, and misappropriation of trade secrets; threaten their immigration status; and seek to have them pay OceanGate's legal fees.
The article also tells a story about OceanGate's 240-foot dive to the wreck of the Andrea Doria in 2016. The article claims that Rush disregarded safety instructions, then "landed too close, got tangled in the current, managed to wedge the sub beneath the Andrea Doria's crumbling bow, and descended into a full-blown panic..."

The article's author marvels that five years ago, "I didn't yet know how reckless, how heedless, how insane the Titan was." They'd once even considered booking a trip on the OceanGate's submersible — until receiving this advice from the chief pilot of the University of Hawaii's two deep-sea submarines. "Do not get into that sub. He is going to have a major accident."

Online publishers are inundated with useless article pitches as websites using AI-generated content multiply. From a report: When she first heard of the humanlike language skills of the artificial-intelligence bot ChatGPT, Jennifer Stevens wondered what it would mean for the retirement magazine she edits. Months later, she has a better idea. It means she is spending a lot of time filtering out useless article pitches. People like Stevens, the executive editor of International Living, are among those seeing a growing amount of AI-generated content that is so far beneath their standards that they consider it a new kind of spam.

The technology is fueling an investment boom. It can answer questions, produce images and even generate essays based on simple prompts. Some of these techniques promise to enhance data analysis and eliminate mundane writing tasks, much as the calculator changed mathematics. But they also show the potential for AI-generated spam to surge and potentially spread across the internet. In early May, the news site rating company NewsGuard found 49 fake news websites that were using AI to generate content. By the end of June, the tally had hit 277, according to Gordon Crovitz, the company's co-founder. "This is growing exponentially," Crovitz said. The sites appear to have been created to make money through Google's online advertising network, said Crovitz, formerly a columnist and a publisher at The Wall Street Journal.

Researchers also point to the potential of AI technologies being used to create political disinformation and targeted messages used for hacking. The cybersecurity company Zscaler says it is too early to say whether AI is being used by criminals in a widespread way, but the company expects to see it being used to create high-quality fake phishing webpages, which are designed to trick victims into downloading malicious software or disclosing their online usernames and passwords. On YouTube, the ChatGPT gold rush is in full swing. Dozens of videos offering advice on how to make money from OpenAI's technology have been viewed hundreds of thousands of times. Many of them suggest questionable schemes involving junk content. Some tell viewers that they can make thousands of dollars a week, urging them to write ebooks or sell advertising on blogs filled with AI-generated content that could then generate ad revenue by popping up on Google searches.

An ancient Nevada lakebed could become a vast source of the lithium used in electric car batteries, reports the Associated Press. But "NASA says the same site — flat as a tabletop and undisturbed like none other in the Western Hemisphere — is indispensable for calibrating the razor-sharp measurements of hundreds of satellites orbiting overhead." At the space agency's request, the U.S. Bureau of Land Management has agreed to withdraw 36 square miles (92 square kilometers) of the eastern Nevada terrain from its inventory of federal lands open to potential mineral exploration and mining. NASA says the long, flat piece of land above the untapped lithium deposit in Nevada's Railroad Valley has been used for nearly three decades to get measurements just right to keep satellites and their applications functioning properly. "No other location in the United States is suitable for this purpose," the Bureau of Land Management concluded in April after receiving NASA's input on the tract 250 miles (400 kilometers) northeast of Las Vegas...

In Railroad Valley, satellite calculations are critical to gathering information beamed from space with widespread applications from weather forecasting to national security, agricultural outlooks and natural disasters, according to NASA, which said the satellites "provide vital and often time-critical information touching every aspect of life on Earth." That increasingly includes certifying measurements related to climate change. Thus the Nevada desert paradox, critics say. Although lithium is the main ingredient in batteries for electric vehicles key to reducing greenhouse gases, in this case the metal is buried beneath land NASA says must remain undisturbed to certify the accuracy of satellites monitoring Earth's warming atmosphere...

The area's unchanged nature has allowed NASA to establish a long record of images of the undisturbed topography to assist precise measurement of distances using the travel time of radio signals and assure "absolute radiometric calibration" of sensors on board satellites. "Activities that stand to disrupt the surface integrity of Railroad Valley would risk making the site unusable," Jeremy Eggers, a spokesman for NASA's Goddard Space Flight Center in Greenbelt, Maryland, told The Associated Press.
One company with most of the mining rights says the tract's withdrawal will put more than half the site's value out of reach, according to the article.

But the Associated Press got a supportive quote for the move from the satellite imaging company Planet Labs, which has relied on NASA's site to calibrate more than 250 of its satellites since 2016. "As our nation becomes ever more impacted by an evolving and changing environment, it is critical to have reliable and accurate data and imagery of our planet."

An anonymous reader shared this report from the Washington Post: An outbreak of severe storms, including deadly tornadoes, hail bigger than DVDs and life-threatening flooding, has ravaged the South, coming amid a month of wild weather across North America. Texas is baking beneath heat indexes as high as 120 degrees, the coasts are cool and mostly calm and Canadian wildfire smoke is suffocating much of the northern U.S.

If it seems the weather has been a little bit "off" since the calendar flipped to June, you're not imagining it — things have been downright weird. It's all linked to a bizarre jet stream pattern, which is displacing air masses from their typical positions and disrupting the movement of weather systems across the continent.
Among other things, the jet stream created a sprawling heat dome in Canada which "helped sap the landscape of moisture, leaving it ripe to burn," the article points out.

"Meanwhile in the southern U.S., the roaring southern branch of the jet stream has been energizing storms. That's brewed back-to-back rounds of severe weather, complete with strong winds, tornadoes and 'gargantuan' hail — and the pattern doesn't look to budge soon." [El Niño] historically, has been linked to split-flow jet stream patterns like the one driving wild weather across parts of the Lower 48. Natural variability, a.k.a. randomness, is also a big player, but it stands to reason that the two factors, overlapping together, are in large part culpable for what we've been facing.

Some scientific research also suggests human-caused climate change may increase the chances of slow, wonky jet stream patterns such as the one being observed this summer. The idea is that the disproportionate warming of the high latitudes is reducing the temperature contrast between the north and south, weakening the jet stream and thus causing it to take bigger dips and meander more. It remains a controversial idea.
