A Chinese inventor with no medical training is charging cancer patients $20,000 to inject highly concentrated chlorine dioxide -- a toxic bleach solution -- directly into their tumors, and is working with a former pharmaceutical executive to bring the unproven treatment to the United States, Wired reports.

Xuewu Liu uses injections containing 20,000 parts per million of chlorine dioxide, significantly higher than the 3,000 ppm concentrations typically found in oral bleach solutions peddled by pseudoscience promoters. One patient told WIRED her tumor grew faster after Liu's injections and suspects the treatment caused her cancer to spread to her skin.

An anonymous reader shares a report: Surveys show that the increasing number of extreme climate events, including floods, wildfires and hurricanes, has not raised awareness of the threats posed by climate change. Instead, people change their idea of what they see as normal. This so-called "boiling frog effect" makes gradual change difficult to spot.

Researchers at Carnegie Mellon University in Pennsylvania wondered if climate change could be made more obvious by presenting it in binary terms. Local newspaper archives describing ice skating on Lake Carnegie when it froze in winter inspired a simple experiment. Some test subjects were shown temperature graphs of a fictional town's winter conditions; others had a chart showing whether or not a fictional lake froze each year. The result, published in Nature, showed those who receiving the second graphic consistently saw climate change as more real and imminent.

Binary data gives a clearer impression of the "before" and "after." The disappearing ice is more vivid and dramatic than a temperature trace, even though the underlying data is the same. "We are literally showing them the same trend, just in different formats," says Rachit Dubey, a co-author of the study. These results should help drive more effective ways of communicating the impact of climate change in future by finding simple binary, black-and-white examples of its effects.

The United States will withdraw from UNESCO for the second time in eight years, with the departure taking effect December 31, 2026. The State Department announced the decision yesterday, ending the country's brief two-year return to the Paris-based United Nations science and cultural organization. The US previously withdrew from UNESCO in 2017, cutting off more than 22% of the agency's funding. The American contribution now represents 8% of UNESCO's current $900 million annual budget, making the financial impact less severe than the earlier withdrawal.

Palmer Luckey, known for founding Oculus and defense-tech firm Anduril, is now eyeing U.S.-manufactured laptops as his next venture. While past American laptops have largely relied on foreign components, Luckey is exploring the possibility of building a fully "Made in USA" device that meets strict FTC standards -- though doing so may cost a premium. Tom's Hardware reports: ["Would you buy a Made In America computer from Anduril for 20% more than Chinese-manufactured options from Apple?" asked Luckey in a post on X.] Luckey previously asked the same question at the Reindustrialize Summit, a conference whose website said it was devoted to "convening the brightest and most motivated minds at the intersection of technology and manufacturing," which shared a clip of Luckey discussing the subject, wherein he talks about the extensive research he has already done around building a PC in the U.S. Luckey wouldn't be the first to make a laptop in the U.S. (PCMag collected a list of domestic PCs, including laptops, in 2021.) But those products use components sourced from elsewhere; they're assembled in the U.S. rather than manufactured there.

That distinction matters, according to the Made in USA Standard published by the Federal Trade Commission. To quote: "For a product to be called Made in USA, or claimed to be of domestic origin without qualifications or limits on the claim, the product must be 'all or virtually all' made in the U.S. [which] means that the final assembly or processing of the product occurs in the United States, all significant processing that goes into the product occurs in the United States, and all or virtually all ingredients or components of the product are made and sourced in the United States. That is, the product should contain no -- or negligible -- foreign content." How much more would you be willing to pay for a laptop that was truly made in America?

The New York Stock Exchange and Nasdaq have applied for regulatory permission to extend their trading hours to 22 and 24 hours daily, respectively. Nasdaq expects to implement round-the-clock trading from the second half of 2026. The London Stock Exchange is considering similar extensions, according to Financial Times. Several retail brokers already facilitate overnight trading through alternative platforms and "dark pools" -- off-exchange venues that operate during non-standard hours. Robinhood began offering all-night trading for select stocks in May 2023, while Charles Schwab announced plans to expand its overnight trading service to 1,100 securities this July. Economist argues that 24/7 trading is a bad idea. The publication writes: The problem with such trading is that price discovery can be fraught with difficulty. In fact, this is partly why institutional investors like dark pools: their lighter reporting requirements, compared with exchanges, allow big orders to be executed without alerting the wider market beforehand, which would move the price. Professionals taking the other side of these trades accept the risks and know how to navigate them. Amateurs, getting a worse price than they might have done in daylight, often do not.

The witching hours are currently when all manner of dull, but vital, post-trade processes take place, from settlement and valuation to the reconciliation of mistakes. Once trading is non-stop, there will be no pause for the financial plumbing to clear. Nor for traders to rest in the knowledge that the market is resting with them, so there is no need to refresh their screens. In today's always-on world, stock exchanges' limited opening hours might seem old-fashioned. But get ready to miss them once they're gone.

A landmark decision by a top UN court has cleared the way for countries to sue each other over climate change, including over historic emissions of planet-warming gases. BBC: But the judge at the International Court of Justice in the Hague, Netherlands on Wednesday said that untangling who caused which part of climate change could be difficult. The ruling is non-binding but legal experts say it could have wide-ranging consequences. It will be seen as a victory for countries that are very vulnerable to climate change, who came to court after feeling frustrated about lack of global progress in tackling the problem.

A cyber-espionage campaign exploiting unpatched Microsoft SharePoint vulnerabilities has breached approximately 400 organizations worldwide, including the US National Nuclear Security Administration, according to Netherlands-based cybersecurity firm Eye Security. The figure represents a four-fold increase from 100 organizations cataloged over the weekend, with researchers calling it likely an undercount since not all attack vectors leave detectable artifacts.

Microsoft identified three Chinese groups -- state-backed Linen Typhoon and Violet Typhoon, plus China-based Storm-2603 -- as exploiting the vulnerabilities in on-premises SharePoint servers to steal authentication credentials and execute malicious code remotely. The campaign began July 7 and was first detected July 18 when Eye Security found unusual activity on a customer's server. Victims include the US Energy Department, Education Department, Florida's Department of Revenue, Rhode Island General Assembly, and European and Middle Eastern governments.

A record-breaking heat wave across Western Europe in June and July has triggered a political battle over air conditioning installation, with right-wing parties demanding widespread adoption while government officials warn of environmental consequences. More than 1,000 French schools closed partially or completely due to lack of air conditioning during the heat wave.

Marine Le Pen's far-right National Rally party proposed a major campaign to install air conditioning in schools, hospitals and other institutions. UK Conservatives urged London's Labour mayor to eliminate restrictions on air conditioning in new housing, while Spain's Vox party highlighted air-conditioning breakdowns to criticize establishment parties. French Energy Minister Agnes Pannier-Runacher countered that large-scale air conditioning would heat streets with exhaust, worsening heat waves.

Europe is the fastest-warming continent, heating twice the global average since the 1980s. One study predicts air conditioning will increase Italy's annual power demand by 10% by 2050.

The United Kingdom's government is planning to ban public sector and critical infrastructure organizations from paying ransoms after ransomware attacks. From a report: The list of entities that would have to follow the new proposed legislation includes local councils, schools, and the publicly funded National Health Service (NHS).

"Ransomware is estimated to cost the UK economy millions of pounds each year, with recent high-profile ransomware attacks highlighting the severe operational, financial, and even life-threatening risks. The ban would target the business model that fuels cyber criminals' activities and makes the vital services the public rely on a less attractive target for ransomware groups," the UK government said.

"We're determined to smash the cyber criminal business model and protect the services we all rely on as we deliver our Plan for Change. By working in partnership with industry to advance these measures, we are sending a clear signal that the UK is united in the fight against ransomware," Security Minister Dan Jarvis added.

For the first time ever, a CCTV camera in Myanmar captured real-time footage of a supershear strike-slip earthquake moving at 3.7 miles per second. According to seismologists at Japan's Kyoto University, the analysis has "led to new findings based on real-time visual evidence of tectonic motion," reports Popular Science. From the report: The magnitude 7.7 event took place on March 28 along the Sagaing Fault with an epicenter near Myanmar's second-largest city, Mandalay. Although the initial rupture process lasted barely 80 seconds, it and numerous aftershocks were ultimately responsible for 5,456 confirmed deaths and over 11,000 injuries. Later evaluations indicated the quake was the second deadliest in modern history, as well as the most powerful to hit Myanmar in over a century. According to a separate group's paper published in the same journal, the southern portion of the rupture occurred at an astonishing 3.7 miles per second -- fast enough to qualify as "supershear velocity."

Amid the catastrophe, an outdoor CCTV camera about 74.5 miles south of the epicenter recorded a visceral illustration of its power. Over just a few moments, what at first looks like a single chunk of the ground appears to suddenly divide and horizontally shift past one another in opposite directions. Completely by accident, the camera recorded a direct look of a strike-slip fault, something previously analyzed by remote seismic instruments. To researchers at Kyoto University, the clip wasn't just a jaw-dropping scene -- it was an opportunity to study a strike-slip fault using visual data. You can watch the footage on YouTube.

Conspiracy theorists drastically overestimate how many people share their beliefs, according to a study published in the Personality and Social Psychology Bulletin. Researchers conducted eight studies involving over 4,000 US adults and found that while participants believed conspiracy claims just 12% of the time, believers thought they were in the majority 93% of the time.

The study examined beliefs about claims such as the Apollo Moon landings being faked and Princess Diana's death not being an accident. In one example, 8% of participants believed the Sandy Hook shooting was a false flag operation, but that group estimated 61% of people agreed with them. "It might be one of the biggest false consensus effects that's been observed," said co-author Gordon Pennycook, a psychologist at Cornell University. The findings suggest overconfidence serves as a primary driver of conspiracy beliefs.

Government funding for a program that hunts for threats on America's critical infrastructure networks expired on Sunday, preventing Lawrence Livermore National Laboratory from analyzing activity that could indicate a cyberattack, the program director told Congress on Tuesday. From a report: Nate Gleason leads a team at Lawrence Livermore National Laboratory (LLNL) focused on nation-state threats against critical infrastructure, and this includes the CyberSentry Program.

It's a public-private partnership, managed by CISA, that looks for malicious activity on IT and operational technology (OT) networks in America's energy, water, healthcare, and other critical facilities. This includes threats along the lines of China's Volt Typhoon and Salt Typhoon intrusions -- network activity that may look like, or even start as, espionage, but ultimately enables the digital invaders to backdoor critical orgs and deploy cyber weapons to aid in a kinetic war.

An anonymous reader quotes a report from Tom's Hardware: At the 2025 RISC-V Summit in China, Nvidia announced that its CUDA software platform will be made compatible with the RISC-V instruction set architecture (ISA) on the CPU side of things. The news was confirmed during a presentation during a RISC-V event. This is a major step in enabling the RISC-V ISA-based CPUs in performance demanding applications. The announcement makes it clear that RISC-V can now serve as the main processor for CUDA-based systems, a role traditionally filled by x86 or Arm cores. While nobody even barely expects RISC-V in hyperscale datacenters any time soon, RISC-V can be used on CUDA-enabled edge devices, such as Nvidia's Jetson modules. However, it looks like Nvidia does indeed expect RISC-V to be in the datacenter.

Nvidia's profile on RISC-V seems to be quite high as the keynote at the RISC-V Summit China was delivered by Frans Sijsterman, who appears to be Vice President of Hardware Engineering at Nvidia. The presentation outlined how CUDA components will now run on RISC-V. A diagram shown at the session illustrated a typical configuration: the GPU handles parallel workloads, while a RISC-V CPU executes CUDA system drivers, application logic, and the operating system. This setup enables the CPU to orchestrate GPU computations fully within the CUDA environment. Given Nvidia's current focus, the workloads must be AI-related, yet the company did not confirm this. However, there is more.

Also featured in the diagram was a DPU handling networking tasks, rounding out a system consisting of GPU compute, CPU orchestration, and data movement. This configuration clearly suggests Nvidia's vision to build heterogeneous compute platforms where RISC-V CPU can be central to managing workloads while Nvidia's GPUs, DPUs, and networking chips handle the rest. Yet again, there is more. Even with this low-profile announcement, Nvidia essentially bridges proprietary CUDA stack to an open architecture, one that seems to develop fast in China. Yet, being unable to ship flagship GB200 and GB300 offerings to China, the company has to find ways to keep its CUDA thriving.

Apple is expected to avoid hefty daily fines from the EU by modifying its App Store policies -- allowing developers to direct users to external payment options and adjusting its fee structure. Reuters reports: The company last month said developers will pay a 20% processing fee for purchases made via the App Store, though the fees could go as low as 13% for Apple's small-business program. Developers who send customers outside the App Store for payment will pay a fee between 5% and 15%. They will also be able to use as many links as they wish to send users to outside forms of payment.

Apple made the changes after the EU antitrust enforcer handed it a 500 million euro ($586.7 million) fine in April, saying its technical and commercial restrictions prevented app developers from steering users to cheaper deals outside the App Store in breach of the Digital Markets Act. The company was given 60 days to scrap the restraints to comply with the DMA aimed at reining in Big Tech and giving rivals more room to compete. The European Commission is expected to approve the changes in the coming weeks, although the timing could still change, the people said. "All options remain on the table. We are still assessing Apple's proposed changes," the EU watchdog said.

The US Department of Homeland Security (DHS) and the US Citizenship and Immigration Services (USCIS) intend to reevaluate how H-1B visas are issued, according to a regulatory filing. From a report: The notice, filed on Thursday with the US Office of Management and Budget's Office of Information and Regulatory Affairs (OIRA), seeks the statutory review of a proposed rule titled "Weighted Selection Process for Registrants and Petitioners Seeking To File Cap-Subject H-1B Petitions."

Once the review is complete, which could be a matter of days or weeks, the text of the rule is expected to be published in the US Federal Register. Based on the rule title, it appears the government intends to change the system for allocating H-1B visas the current lottery to some system that will favor applicants who meet specified criteria, possibly related to skills.

The H-1B visa program, which reached its Fiscal 2026 cap on Friday, allows skilled guest workers to come work in the US. As of 2019, there were about 600,000 H-1B workers in the US, according to USCIS. The foreign worker program is beloved by technology companies, ostensibly to hire talent not readily available from American workers. But H-1B -- along with the Optional Practical Training (OPT) program -- has long been criticized for making it easier to undercut US worker wages, limiting labor rights for immigrants, and for persistent abuse of the rules by outsourcing companies.

ChatGPT now handles 2.5 billion prompts daily, with 330 million from U.S. users. This surge marks a doubling in usage since December when OpenAI CEO Sam Altman said that users send over 1 billion queries to ChatGPT each day. TechCrunch reports: These numbers show just how ubiquitous OpenAI's flagship product is becoming. Google's parent company, Alphabet, does not release daily search data, but recently revealed that Google receives 5 trillion queries per year, which averages to just under 14 billion daily searches. Independent researchers have found similar trends. Neil Patel of NP Digital estimates that Google receives 13.7 billion searches daily, while research from SparkToro and Datos -- two digital marketing companies -- estimates that the figure is around 16.4 billion per day.

An anonymous reader shares a report: In 2023 and 2024, the hottest years on record, more than 78 million acres of forests burned around the globe. The fires sent veils of smoke and several billion tons of carbon dioxide into the atmosphere, subjecting millions of people to poor air quality. Extreme forest-fire years are becoming more common because of climate change, new research suggests.

"Climate change is loading the dice for extreme fire seasons like we've seen," said John Abatzoglou, a climate scientist at the University of California Merced. "There are going to be more fires like this." The area of forest canopy lost to fire during 2023 and 2024 was at least two times greater than the annual average of the previous nearly two decades, according to a new study published Monday in the journal Proceedings of the National Academy of Sciences.

The researchers used imagery from the LANDSAT satellite network to determine how tree cover had changed from 2002 to 2024, and compared that with satellite detections of fire activity to see how much canopy loss was because of fire. Globally, the area of land burned by wildfires has decreased in recent decades, mostly because humans are transforming savannas and grasslands into less flammable landscapes. But the area of forests burned has gone up.

FCC Chairman Brendan Carr is proposing (PDF) to roll back key Biden-era broadband policies, scrapping the long-term gigabit speed goal, halting analysis of broadband affordability, and reinterpreting deployment standards in a way that favors industry metrics over consumer access. The proposal, which is scheduled for a vote on August 7, narrows the scope of Section 706 evaluations to focus on whether broadband is being deployed rather than whether it's affordable or universally accessible. Ars Technica reports: The changes will make it easier for the FCC to give the broadband industry a passing grade in an annual progress report. FCC Chairman Brendan Carr's proposal would give the industry a thumbs-up even if it falls short of 100 percent deployment, eliminate a long-term goal of gigabit broadband speeds, and abandon a new effort to track the affordability of broadband.

Section 706 of the Telecommunications Act requires the FCC to determine whether broadband is being deployed "on a reasonable and timely basis" to all Americans. If the answer is no, the US law says the FCC must "take immediate action to accelerate deployment of such capability by removing barriers to infrastructure investment and by promoting competition in the telecommunications market."

Generally, Democratic-led commissions have found that the industry isn't doing enough to make broadband universally available, while Republican-led commissions have found the opposite. Democratic-led commissions have also periodically increased the speeds used to determine whether advanced telecommunications capabilities are widely available, while Republican-led commissioners have kept the speed standards the same.

NVIDIA has released additional open-source header files for its Blackwell and Hopper GPU architectures, continuing its effort to support open-source drivers like Nouveau/NVK and the NOVA Rust driver. Phoronix reports: Last week NVIDIA open-sourced 12k lines of C header files for Blackwell GPUs to help in the open-source driver efforts, namely for Nouveau / NVK and the in-development NOVA Rust driver. On Friday they made public some additional header files for helping in the Blackwell and Hopper open-source driver enablement.

Following the previously-covered open-source header activity, on Friday this commit was pushed to their open-source documentation repository that provides Hopper and Blackwell DMA-copy class header files. [...] In turn the code has already been imported into Mesa Git.

Sir Keir Starmer's government is seeking a way out of a clash with the Trump administration over the UK's demand that Apple provide it with access to secure customer data, Financial Times reported Monday, citing two officials. From the report: The officials both said the Home Office, which ordered the tech giant in January to grant access to its most secure cloud storage system, would probably have to retreat in the face of pressure from senior leaders in Washington, including Vice President JD Vance.

"This is something that the vice president is very annoyed about and which needs to be resolved," said an official in the UK's technology department. "The Home Office is basically going to have to back down." Both officials said the UK decision to force Apple to break its end-to-end encryption -- which has been raised multiple times by top officials in Donald Trump's administration -- could impede technology agreements with the US.
