The High-Luminosity LHC will be mostly the same machine, but it'll deliver 10 times the luminosity and just as little chance of destroying the universe - sorry, conspiracy theorists:

The end has come for CERN's Large Hadron Collider (LHC), but it's not being turned off for fear of the world being sucked into some sort of cosmic anomaly - it's getting a major upgrade. 

Physicists at CERN are still bidding goodbye to the LHC, per a Monday announcement from the lab, but this is very much a "the king is dead, long live the king" sort of moment, as the four-year shutdown will result in the completion of the High-Luminosity LHC, or HiLumi LHC, not a full-fledged replacement.

In essence, a younger, fitter model with much better eyesight and most of the same genes will be taking the throne as the world's largest particle accelerator, or human-made machine, for that matter, when it comes online in 2030 after what the lab is calling Long Shutdown 3.

HiLumi LHC will feature a number of upgrades. As its name suggests, increased luminosity is the biggest difference between the new model and the old LHC, which was first switched on in 2008.

Luminosity, as CERN explains, is proportional to the number of collisions produced in a given time. Those collisions are detected in the ATLAS and CMS detectors at the LHC (the pair were responsible for the world's first detection of the Higgs boson in 2012), which will be getting some major upgrades that, per CERN, will effectively make them into entirely new detectors.

Place your bets, because it looks increasingly unlikely Boeing's Starliner spacecraft will carry astronauts again, if a NASA inspector general's report is anything to go on.

Published on Tuesday, the OIG report on NASA's management of its Commercial Crew Program (CCP) examines how SpaceX and Boeing have performed in providing crew transportation to the International Space Station. The report notes that SpaceX worked through its own technical challenges getting humans into space and to the ISS.

Boeing's Starliner, a.k.a. the Calamity Capsule, on the other hand, featured extensively in the writeup, with the OIG calling into question whether it'll ever get past the testing phase.

"Boeing has been unable to obtain human-rating certification for its Starliner capsule and Atlas V launch vehicle, conducting two orbital flight tests and one crewed flight test that suffered significant issues and was ultimately classified as a serious mishap," the OIG report said. "With over 11 years invested and about 4 years of crewed operations aboard the ISS remaining until the Station's planned decommission in 2030, NASA and Boeing have limited time and resources to realize the value of their significant investments into Starliner." 

The saga of Boeing's Starliner has been one of repeated failures and budget overruns, both at NASA and Boeing, thanks to the capsule's disastrous launch record. 

As the NASA OIG noted in its report, Starliner has flown three test missions, one with crew, and each encountered significant technical problems. 

The first flight, in 2019, failed to reach the ISS because a software-related mission timing error caused an incorrect orbital insertion burn, preventing the spacecraft from docking. Problems with stuck oxidizer valves discovered ahead of a planned 2021 launch delayed the second orbital flight test until May 2022, when Starliner successfully reached the ISS despite experiencing thruster failures and helium leaks.

In other NASA news, the agency announced some new commercial Moon landing plans Tuesday that included a truly oddball idea: Sending an engineering development model of a Mars rover to the Moon instead of a purpose-built one. 

The rover, which currently lives at NASA's Jet Propulsion Laboratory and serves as a testbed for Curiosity and Perseverance, could be repurposed as the Polar Rover for Observation, Mapping, and In-Situ Exploration, or PROMISE, if Isaacman gets his way. 

The move would mean that a rover that was never meant for actual space exploration would be doing just that, and it'd also mean that JPL was left without its engineering model for two active rovers on Mars. NASA didn't respond to questions about the plan. 

NASA was going to get a pair of astronauts up in the craft in 2023, but that didn't happen after a series of issues were discovered, including a faulty parachute system and flammability risks associated with tape used to protect internal wiring. 

The one crewed mission that Starliner attempted was also a disaster. No one was injured or killed in the incident, but NASA astronauts Butch Wilmore and Suni Williams were stranded on the ISS for months after NASA determined the craft wasn't safe enough to return its crew to Earth.

According to the OIG, it's the parachute problems, along with persistent helium leaks and the aforementioned propulsion system failures, that are making it question whether Starliner is fit for purpose. 

"The helium leaks and propulsion systems failures remain unresolved as of March 2026, and NASA is uncertain as to when this testing will be completed or human-rating certification for the Starliner will be obtained," the report states. 

The OIG placed the blame on both NASA and Boeing for the problems, similarly to what NASA Administrator Jared Isaacman said earlier this year when he accepted that his agency was part of the reason the whole thing had gone so badly.

Per the OIG, NASA contributed to the problem by being "overconfident in Boeing's design and potential success based on the provider's use of heritage systems," which led to the space agency setting "unrealistic launch and flight test schedules." 

"The pressure to adhere to this aggressive schedule was compounded by NASA's underutilization of the contract's data rights, limiting the Agency's ability to fully analyze and resolve flight simulation training failures to ensure crew safety," the report continued. Staffing constraints driven by the Trump administration's desire to cut costs wherever it can find them are likely to further hinder oversight, the OIG said, calling into question once more whether the Calamity Capsule will ever fly again and whether it's worth the cost.

"We question $127.9 million in payments to Boeing, in addition to the $43 million we questioned in a prior 2019 CCP-related report, for a mission that is far from certain," the OIG said. 

In other words, if you want to trim some NASA fat, the Starliner budget's a perfect place to do it.

Oomwoo is a new open-source robot vacuum you can 3D print yourself, sidesteps cloud security risks by running fully offline — project combines Raspberry Pi, 2D LiDAR, and a 3D-printed chassis:

Maker's Pet has launched oomwoo , an open-source robot vacuum that owners build themselves. The robot works by mapping the home with an inexpensive 2D LiDAR sensor and then navigating using ROS 2 and the Nav2 stack on Raspberry Pi, integrating natively with Home Assistant. It can be printed using a regular desktop 3D printer and runs entirely without the cloud, while the hardware, firmware, and software are all open under the Apache 2.0 license. Ilia O of Maker's Pet is also developing oomwoo in public "from the first commit," though the project is so early that it doesn't have any build instructions yet.

Right now, oomwoo is at the request-for-comments stage, with the current v0 milestone covering a 3D-printed chassis, a ROS 2 Gazebo simulation, and LiDAR mapping with manual SLAM, and the compute choice between a Raspberry Pi 5, an ESP32 running micro-ROS, or both is still open. Planned deliverables run from the bill of materials and printable files to firmware and a custom PCB, with the first BoM targeted for around mid-July.

The project is structured so the community can build it in parallel: the robot is split into self-contained modules, and contributors claim one and submit work as a pull request. A convenience kit will be sold through Maker's Pet, but Ilia says that buying it won't be a requirement, and every part can be sourced independently.

The usual route to a cloud-free robot vacuum starts with a robot you already own. Valetudo, maintained by Sören Beye since 2018 and also released under Apache 2.0, replaces a commercial vacuum's cloud connection with local-only control and Home Assistant integration. Installing it, however, means rooting the vendor firmware, which on many supported Dreame, Roborock, and Xiaomi models requires disassembly and voids the warranty, and also can't be undone.

The inclusion of local control could be a boon for getting more tinkerers and enthusiasts on board with the vacuum, following several examples of robot-vacuum security failures over the last few years. At DEF CON 32 in August 2024, researchers Dennis Giese and Braelynn Luedtke showed that several Ecovacs models could be hijacked over Bluetooth to reach their cameras and microphones, with Giese telling TechCrunch the security was "really, really, really, really bad."

Hijacked DEEBOT X2 units later shouted slurs and chased pets in several U.S. homes, and a token flaw in DJI's Romo line let one tinkerer reach roughly 6,700 vacuums worldwide , floor plans, and live feeds included. One owner went as far as reviving a remotely bricked vacuum with custom boards and Python to run it offline. oomwoo's reference design eliminates that attack surface, navigating on 2D LiDAR and bumper sensors with nothing pointed at the room.

https://arstechnica.com/gaming/2026/07/sony-will-stop-making-physical-copies-of-playstation-games-in-2028/

Some gamers are concerned about the future of game ownership after Sony's announcement today that it won't produce physical discs for PlayStation games as of January 2028. On that date, "new games will be available on PlayStation Store and at retailers in digital formats only," Sony said in a blog post.
[...]
"We'll continue to prioritize our resources to drive innovation in how players can access games and provide choices as to where players prefer to purchase new games, whether that's at retailers or PlayStation Store," the blog said.

No companies other than Sony subsidiary Sony Digital Audio Disc Corporation make PlayStation discs, so today's announcement signals the end of physical copies of PlayStation games and marks Sony's evolution toward a licensing-only sales model.
[...]
buying a digital download is not the same as owning a game. Per PlayStation's terms of service:

When you order or purchase a product from PlayStation Store, you buy a personal license to use that product for private, non-commercial use. That license is not transferable unless your local applicable laws say it must be. This means you can use a product in the ways described in the license, but do not own the product.

[...]
Sony also announced today that it will close the PlayStation Store on PlayStation 3 and PS Vita, with the US losing access in July 2027.
[...]
"To ease the transition, players will still be able to download previously purchased content after the closing date for the foreseeable future," Sony said.

Both blog posts have comments decrying Sony's announcements and their implications for ownership and long-term access to PlayStation games.

One user going by Mosquito53, for example, commented:

Another disappointing decision made in the same day. No matter how many users still use these stores, they should remain open. So much content released digital-only, even on these platforms, these games will be lost to time.

Imagine what will happen in the future when this same decision is made for PS4 or PS5 or even the eventual PS6, which now looks to be all digital with the announcement of no more physical disc production.

We will own nothing, it's truly sad.

[...]
in 2024, Sony deleted customers' Funimation digital libraries despite Funimation previously claiming that customers would be able to access these digital copies "forever but" with "some restrictions."
[...]
Sony has also shown a wavering commitment to its digital stores. In 2021, it stopped selling movie and show rentals/purchases. Leaving the door ajar for customers to potentially lose access to digital games they bought for PlayStation 3 or PS Vita doesn't boost confidence around the digital-only future.

Further, the removal of storefronts could mean beloved games released only digitally become virtually impossible to find.
[...]
"This is why physical media matters," a user named Radgatt commented on Sony's PS3 and PS Vita announcement. "More and more proof that you're just buying a license that can be taken away whenever companies feel like it.

Engineer open-sources DIY radar system that's 95% cheaper than $250,000 commercial offerings, has 20 kilometer range — Moroccan engineer designs Aeris-10 radar, shares it on GitHub:

"Nice radar you got there," followed by "thanks, I just had it jammed," might be the new word exchange among buddy electronics enthusiasts. In a move that might ruffle the feathers of many large companies with exceedingly pricey wares, a Moroccan electronics engineer named Nawfal Motii has designed the open-source Aeris-10 radar system that is purportedly comparable to commercial systems costing $250,000.

Aeris-10 comes in two variants: 10N Nexus with a 3-km range and an 8x16 patch antenna array, and the 10E Extended, capable of reaching up to 20 km thanks to its 32x16 slotted waveguide array. Motii published the entire project on GitHub , including all the necessary schematics, PBC layouts, components, firmware, and software with a GUI for controlling and monitoring the system.

On the technical end, the Aeris-10 uses an XCA7A50T FPGA as a central brain for doing its FFT math, along with Moving Target Indicator (MTI), Doppler-effect estimation of moving object speed, and CFAR false alarm detection control. The figurative spinal cord is an STM32F746xx microcontroller that orchestrates the frequency synthesizers, ADCs, DACs, the GPS, barometer, stepper motors, and cooling setup.

Watch full video on the link above:

The fact that Aeris-10 offers a true phased array system and ±45° elevation/azimuth adjustments are seemingly its differentiating factors. Prices for electronics are exceedingly floaty in these ship-shinking days, but a brief estimate pins the bill of materials at $5,000 for the 10N and $7,200 for the 10E. Despite the number of zeros on those figures, they're pocket change compared to amounts commanded by off-the-truck offerings. A cursory look puts commercial phase-array systems at somewhere $120k and $200k, and well past those prices for longer-range units.

Motii claims that military surplus radars can be had for $10k to $50k, but those are invariably decades-old tech with next to no spare parts availability. He says that building a DIY system is also a hard ask for a small team, as the testing gear can cost $50k on its own. Describing himself as "a guy in a workshop in Morocco with a soldering iron and an obsession," he took it upon himself to fix that particular problem.

Anyone can hit the project's GitHub page and get their own radar system going, but not everyone might have the necessary electronic and mechanical skills necessary for building one. To that effect, Motti says he's reached an agreement with the Crowed Supply platform, aiming for a Q3 2026 release. The site isn't your standard dice-rolling crowd-sourcing platform, though, as apparently it only accepts fully-designed projects with functional prototypes, rejects 90% of submissions, and claims it never had a scam.

Interestingly enough, this project was originally licensed under the MIT license, but Motti was advised that said license does not protect physical hardware, so it changed to the CERN-OHL-PT license. Should you elect to build your own unit, be aware that the frequencies it operates in are almost assuredly highly regulated in your legal jurisdiction.

I'm not even going to summarize this, but if you value American science you need to read it.

Near the end of May, the Office of Management and Budget (OMB) proposed a new rule that would govern how the federal government handles the grants it issues, including those that fund the vast majority of scientific research in the US.

If formalized, the rule would make political priorities the prime determinant of what science gets funded and sideline the opinions of scientific experts. Grants could be canceled due to political whims, and new layers of bureaucracy would inhibit basic scientific activities like publishing papers and attending conferences. Unlike the executive orders it echoes, it would have the force of law behind it and be significantly harder to challenge in court.

Before coming into force, however, the proposal must go through a process that includes public feedback and (potentially) changes in response. The deadline for that feedback—Monday, July 13—is rapidly approaching.

I'm here to explain what makes this proposal so dangerous, why your feedback matters, and how you can craft an effective submission.

Three companies that account for 90% of RAM revenue are being sued for anti-competitive practices.

The big story in computing these days is how an ongoing shortage of RAM (dubbed RAMageddon or the RAMpocalypse) has led to massive increases in hardware costs. The conventional explanation of the situation has been that shortages have been driven by the widespread construction of AI data centers. However, a new lawsuit (Garciaguirre et al. v. Samsung Electronics Co., Ltd., et al.) filed against RAM manufacturers Samsung, SK Hynix, and Micron, alleges that these companies are exploiting market conditions to artificially inflate prices.

The class action lawsuit filed by 14 individuals and three businesses accuses Samsung, SK Hynix, and Micron of conspiring to fix prices and supply of DDR3 and DDR4 RAM, resulting in higher costs. "This lawsuit seeks to recover for—and stop—concerted anticompetitive behavior by three oligopolists in the market for dynamic random access memory, more commonly called DRAM," the opening line of the suit reads.

DRAM is essential for virtually every computing device, as it stores the bits used for short-term data. Samsung, SK Hynix, and Micron account for more than 90% of global DRAM revenue. The suit says that the firms have "fixed supply and prices for DRAM, engaging in conduct that makes no economic sense absent collusion and that has driven up the price of conventional DRAM (sometimes called commodity DRAM) approximately 700% in a four-year period."

Polestar, the Swedish maker of electric vehicles, will not be allowed to sell new vehicle models in the US. It says it will continue to sell existing stock of Polestar 3 and Polestar 4 models. 

The Swedish manufacturer of electric vehicles, which became a distinct brand in 2017, revealed the ban in an SEC filing, which it paired with a press release this week announcing that it's shifting manufacturing to Europe.

It said in the release that it will continue to sell existing stock of its Polestar 3 and Polestar 4 vehicles in the US and to support customers through its service network. 

A representative for Polestar told CNET in an email that, because of the Commerce Department's decision, the company has no plans to sell new cars in the US from model year 2027 onward, including the planned Polestar 7.

The company has marketed the Polestar 7 as a premium compact SUV. It's due out in 2028.

This decision isn't surprising: A 2024 letter from Polestar (PDF) to the Bureau of Industry and Security foreshadowed what would eventually happen. It said at the time that the agency's prohibitions could eventually lead the company to stop selling vehicles in the US, even ones it manufactures in South Carolina.

The US ban has not been posted on the Commerce Department's website or social media, but it's in line with the agency's directive to police technology from China that the government considers a potential security threat. This month, the department issued a $36 million penalty against Bosch for exporting sensors and auto software to Huawei. 

In May, however, the Bureau of Industry and Security granted Volvo special authorization to sell its vehicles in the US after the auto company said it discussed its connected technology with the department. 

A representative of the Bureau of Industry and Security did not immediately respond to a request for comment.

US agencies aren't just looking at the auto industry. The Federal Communications Commission has targeted consumer products including routers and drones that have technology made in China.

Polestar is not one of the top 10 EV manufacturers, lagging behind larger companies including Tesla, BYD and Volkswagen. 

Electric vehicles only account for about 6.5 percent of the US auto market, according to industry watcher Edmunds. In the US, EVs are typically priced higher, and federal rebates to purchase these types of vehicles have been phased out. 

With gas prices high this summer, consumers may be giving EVs another look, but concerns remain about pricing and range. 

Some automakers are trying to boost the appeal of electric vehicles through lower-cost models. Slate is taking preorders for a basic, modular EV truck that costs $24,950 before delivery fees. Other EV models, such as the Chevrolet Bolt, can be found for about $30,000.

The Internet Archive and the Authors Alliance are producing a six-part series from the Future Knowledge podcast. The series, Vanishing Culture explores what happens when our shared cultural heritage disappears, and what we can do to preserve it. The first episode was published July 1^st, 2026 starts out discussing the growing threat of cultural loss in the digital age:

From disappearing websites and deleted social media archives to lost films, books, music, and video games, Luca explores why culture vanishes and why it matters. He explains how copyright law, corporate control of digital platforms, and the shift from ownership to licensing are making it harder for libraries, archives, and communities to preserve cultural memory. Along the way, he shares stories that illustrate both the fragility of our digital heritage and the importance of preserving it: from a favorite YouTube recipe rescued by the Wayback Machine to the role cultural artifacts play in memory and identity. The conversation wraps on a positive note, with a look toward solutions and what creators, libraries, and everyday citizens can do to help ensure culture remains accessible for generations to come.

There is also a open access ebook with the same title, Vanishing Culture from this year by Luca Messarra, Chris Freeland, and Juliya Ziskina. It's available from the Internet Archive as EPub or PDF. See also another open access book, Walled Culture: A Journey Behind the Copyright Bricks, from 2022 by Glyn Moody.

In addition to all the other problems, digital goes away by default once active support stops. Contrast that with paper, microfilm, and microfiche which have to have someone expend time and effort (aka money) to be disposed of or, better, you can keep the copy you have regardless of other factors. Physical media are also decentralized, where as with digital information, there is often only a single copy in the world. Yes, the physical media disappear and rot if neglected, but it is a far cry from the out-like-a-light loss that digital information is afflicted by — unless proactive efforts are taken, such as the heroic efforts by the Internet Archive and other archiving services.

An interesting interview with Cory Doctorow

Sci-fi author/tech journalist Cory Doctorow on his new book, The Reverse Centaur's Guide to Life After AI.

The prolific Doctorow is back with a provocative new book that serves as a follow-up of sorts, focusing on AI and related issues: The Reverse Centaur's Guide to Life After AI. [Available wherever books are sold. --Ed]

Doctorow doesn't actually enjoy talking about AI, but he's constantly being asked to comment on it. "I made the tactical error of being sick of talking about AI," Doctorow told Ars. "So I wrote a book about why I think it's a dumb thing to keep asking people to talk about, and now I have to talk about it." Reverse Centaur is Doctorow's attempt to "sort out the bullshit from the material reality."

In automation theory, per Doctorow, a "centaur" describes a human augmented with a technology, like machine learning, or even just driving a car or using autocomplete. A reverse centaur "is a machine head on a human body, a person who is serving as a squishy meat appendage for an uncaring machine," Doctorow said in a speech last December. He gave the example of an Amazon delivery driver, surrounded by AI cameras monitoring their driving, who essentially serves as a peripheral to the delivery van.

https://www.engadget.com/2203145/nasa-tests-in-orbit-refueling-device-deep-space-missions/

Future deep space missions may need to refuel in orbit before they can head to their final destinations. NASA has been working on in-orbit refueling solutions for years, and one of its latest efforts is testing a "cryocoupler" developed by American tech company L3Harris. You can think of the cryocoupler as the nozzle of a gas pump, which is needed so it can fit a car's fuel tank. Cryocouplers will allow spacecraft to link to orbiting gas stations, so they can fill up before they leave the vicinity of our planet.

"In-orbit cryogenic refueling between two spacecraft has yet to be done and remains one of the toughest engineering challenges in spaceflight," said Travis Belcher, cryocoupler project manager at NASA's Marshall Space Flight Center in Huntsville, Alabama. Effective cryocouplers will have to be able to facilitate the transfer of extremely cold fluid, such as liquid hydrogen and liquid oxygen, without leaking. And since these propellants have to stay chilled at hundreds of degrees below Fahrenheit, the device will need to have the proper materials and strong seals. They (obviously) cannot be manually operated, as well.

"The cryocouplers we're working on can attach and detach multiple times and are fully automated, so astronauts won't have to perform a spacewalk to transfer propellant," Belcher added. "They're rigorously designed to withstand space and sized for the expected tank designs."

To test L3Harris' cryocoupler, Belcher's team ran liquid nitrogen at negative 321 degrees Fahrenheit through several connected and disconnected configurations. Those tests provided the team with data on how the device reacts to significant temperature differences. They also put the coupler through operational tests, such as simulations of misaligned dockings, as the device was designed to accommodate some degree of misalignment.

It's early days for L3Harris' cryocoupler, so these tests are pretty basic. Belcher says future tests will be designed for specific missions, so the coupler can be assessed according to those missions' requirements. For now, you can watch part of the test below.

Swarms of cyborg insects controlled remotely via electrical implants can now operate underwater, thanks to tiny diving suits supplying them with oxygen – which could one day enable them to explore Mars.

Hirotaka Sato at Nanyang Technological University in Singapore and his colleagues first demonstrated in 2021 that Madagascar hissing cockroaches (Gromphadorhina portentosa) could be remotely controlled with electrodes embedded in sensory organs known as cerci. In 2024, they demonstrated that a swarm of 20 of these cyborg insects could coordinate.

The aim was to develop biological robots equipped with infrared sensors that could be released in large numbers after natural disasters to search for survivors. Cockroaches represent a ready-made platform for such applications with a working fuel source, efficient locomotion and in-built reflexes to dodge obstacles – capabilities that engineers still struggle to replicate mechanically at such a small scale.

But Sato and his team were unhappy with the insects’ inability to search flooded areas, which aren’t uncommon in disaster zones, so they have developed a diving suit to allow them to operate underwater.

Cockroaches breathe through pores called spiracles on their abdomen and thorax. The researchers 3D printed a watertight resin suit, which protects the abdominal spiracles from water. Tiny hoses run forwards from the suit to connect directly to the thorax spiracles; the main part of the suit would interfere with leg movement if it covered the thorax as well.

Rather than supplying the insects with a pressurised tank of oxygen, as scuba suits do, the researchers included a mixture of hydrogen peroxide and manganese dioxide. When these two chemicals react, the hydrogen peroxide decomposes to produce oxygen, which the cockroach can absorb.

While wearing the suit, the cockroaches were able to walk underwater for up to 3 hours at a time, at depths of up to 50 centimetres, with no ill effects: all five insects that were monitored after wearing the suits were still healthy three days later.

The suits also allowed the insects to move underwater surprisingly naturally. On land, the suit-wearing cyborg insects achieved an average forward speed of 87.5 millimetres per second, and this only slowed to 78.4 millimetres per second underwater.

Sato says such suits could make search-and-rescue cyborg insects far more capable, but he also hopes to explore their use in space, another environment lacking in vital oxygen.

“The ultimate goal is to [take this technology to] space,” he says. “It’s kind of one step, one big step, towards space suits for cyborg insects. Exploration over the Mars surface, for example.”

To this end, the research team now intends to test the cockroach suits in the various harsh conditions that they could encounter in orbit or on the surface of a planet like Mars: very low and high temperatures, a vacuum and intense radiation exposure. However, space agencies may not like the idea of sending cockroaches to Mars because it would risk contaminating the planet with microbes from Earth.

Alan Winfield at the University of the West of England says the concept of scuba-diving cockroaches may seem strange, but it has obvious applications, such as environmental monitoring.

“There have been attempts to build very small robots, but the problem is batteries. With a very small robot, you typically don’t get very much battery life,” he says. “People often used to say to me, what are the three big problems in mobile robots? And I’d say: energy, energy and energy.”

Cockroaches are not only vastly more efficient than robots and able to operate for longer without refuelling, they are also capable of foraging for their own food in the wild and operating almost indefinitely.

https://arstechnica.com/tech-policy/2026/06/supreme-court-ruling-guts-governments-use-of-geofence-warrants/

The Fourth Amendment protects a user's "location history," the Supreme Court ruled [.PDF] Monday.

The same logic already applied to a cellphone's tracking, and the high court found "no good reason exists to reach a different result for Location History" collected by third parties like Google.

Split 6-3, the majority agreed that the government needs a warrant and must show reasonable cause to turn a phone's location-tracking services into a government surveillance tool.

The decision came in a case where cops used so-called geofence warrants to track down an armed bank robber from a list of all phones logged in the area. Applying a three-part process, cops worked with Google to narrow down the list of suspects and eventually arrested Okello Chatrie, who had opted in to share his location with Google every few minutes. Chatrie was sentenced to 12 years in prison but challenged the geofence warrant as an unconstitutional search.

The US tried and failed to argue that no search was conducted under the Fourth Amendment, partly because they only searched a little bit of Chatrie's location data, which the government considered too small to warrant privacy protections.

They also claimed that Chatrie was aware that voluntarily sharing his location with Google could mean that law enforcement might get access to the data. And along similar lines, the government argued that Chatrie's data simply showed his movements in public, where he supposedly had no reasonable expectation of privacy.

However, Justice Elena Kagan, penning the majority opinion, said it didn't matter how much data the government obtained. It was still a search under the Fourth Amendment because people carrying cellphones today commonly opt in to location-tracking, so that their apps work.

"Google repeatedly prompts users to turn on the service, often warning that devices will not 'work correctly' otherwise, while not disclosing in that prompt how frequently users' location information would be recorded, how precise it would be, or how it might be given to the government," the majority agreed.

Much like carrying a cellphone is part of modern life, so is allowing a third party to track your movements, and that doesn't diminish a person's right to privacy, the majority ruled. Justice Sonia Sotomayor noted that "even short-term monitoring" of where a person has been can reveal "a wealth of detail about [his] familial, political, professional, religious, and sexual associations"—particularly if he's seen visiting a sensitive location, like a clinic, an attorney's office, or a strip club.

"An individual has a reasonable expectation of privacy in records about his cell phone's location, and police intrude on that constitutionally protected interest when they demand the information—even though for only a limited time, and from a third-party tech company," Kagan wrote.

Privacy advocates cheered the ruling, even though it "stopped short of striking down these warrants as inherently unconstitutional," the surveillance litigation director of the Electronic Frontier Foundation, Andrew Crocker, said in a statement provided to Ars.

"We applaud the Court's decision," Crocker said. "The Court reaffirmed that you have an expectation of privacy in location data that reveals your movements in the physical world, and that even short-term surveillance of these movements is a search subject to the Fourth Amendment."
