Solar panels in space could cut Europe's terrestrial renewable energy needs by 80% by 2050, a study has found. The Guardian: Using a detailed computer model of the continent's future power grid, the researchers found that a system of space-based panels designed by Nasa could reduce the cost of the whole European power system by as much as 15%. It could also cut battery use by more than two-thirds.

The study, led by researchers at King's College London, is the first to assess the possible impact of space solar energy on Europe. The space-based solar power (SBSP) panels that yielded the positive results uses a heliostat design. The design, which the system imitates, uses mirror-like reflectors to collect sunlight in orbit. The sunlight is then transmitted to stations on Earth and converted to electricity before it is delivered to an energy grid. The computer model of the continent's power grid spans 33 countries, and simulates electricity demand, generation and storage to identify the lowest-cost option to meet Europe's electricity needs.

President Donald Trump says his administration will not approve solar or wind power projects, even as electricity demand is outpacing the supply in some parts of the U.S. From a report: "We will not approve wind or farmer destroying Solar," Trump, who has complained in the past that solar takes up too much land, posted on Truth Social. "The days of stupidity are over in the USA!!!"

The president's comment comes after the administration tightened federal permitting for renewables last month. The permitting process is now centralized in Interior Secretary Doug Burgum's office. Renewable companies fear that projects will no longer receive permits that were once normal course of business.

Abu Dhabi is gathering the DNA of Emirati newborns in a significant expansion of a national genomic sequencing project that aims to put the UAE on the cutting-edge of health care. From a report: The UAE capital has so far mapped the genomes of 68% of Emirati citizens, a spokesperson for M42, the firm running the program, told Semafor, while at-birth sequencing is being offered to parents on a voluntary basis across several hospitals, and aims to detect over 800 treatable childhood genetic conditions. Only around 1% of the world's mapped genomes are of Arab descent. The UAE is looking to address the gap while tackling public health issues and expanding personalized health care offerings.

FTC, in a press release Wednesday: The Federal Trade Commission today sued the operators of LA Fitness and other gyms over allegations they make it exceedingly difficult for consumers to cancel their gym memberships and related services that continued indefinitely unless cancelled. The agency is seeking a court order prohibiting the allegedly unfair conduct and money back for consumers harmed by the difficulty in cancelling memberships.

"The FTC's complaint describes a scenario that too many Americans have experienced -- a gym membership that seems impossible to cancel," said Christopher Mufarrige, Director of the Bureau of Consumer Protection. "Tens of thousands of LA Fitness customers reported difficulties -- cancellation was often restricted to specific times or required speaking to specific managers who were often not present or available. The FTC will not hesitate to act on behalf of consumers when it believes companies are stifling consumers' ability to choose which recurring charges they want to keep."

India has moved a legislation to ban online money gaming due to rising instances of addiction, money laundering and financial frauds through these apps. From a report: A bill passed in the lower house of Parliament on Wednesday seeks to prohibit promotion and operation of gaming apps that require users to pay money for the chance to win cash. The move threatens India's $3.8 billion gaming industry that has drawn global investors and also fostered homegrown fantasy sports betting apps such as Dream11, Games24X7 and Mobile Premier League.

"People lose their life's savings in online money gaming," India's Minister for Information and Broadcasting Ashwini Vaishnaw told lawmakers in New Delhi. He said the government intends to curb the addiction and financial harm that comes with online money gaming, but will promote e-sports and social gaming.

The melting of sea ice in the Arctic has slowed dramatically in the past 20 years, scientists have reported, with no statistically significant decline in its extent since 2005. From a report: The finding is surprising, the researchers say, given that carbon emissions from fossil fuel burning have continued to rise and trap ever more heat over that time. They said natural variations in ocean currents that limit ice melting had probably balanced out the continuing rise in global temperatures. However, they said this was only a temporary reprieve and melting was highly likely to start again at about double the long-term rate at some point in the next five to 10 years.

The findings do not mean Arctic sea ice is rebounding. Sea ice area in September, when it reaches its annual minimum, has halved since 1979, when satellite measurements began. The climate crisis remains "unequivocally real," the scientists said, and the need for urgent action to avoid the worst impacts remains unchanged. The natural variation causing the slowdown is probably the multi-decadal fluctuations in currents in the Atlantic and Pacific oceans, which change the amount of warmed water flowing into the Arctic. The Arctic is still expected to see ice-free conditions later in the century, harming people and wildlife in the region and boosting global heating by exposing the dark, heat-absorbing ocean.

India Dispatch: The strongest case for India is not merely that it is young, but that it still has time, and it may be the only continental-scale economy that still has it in abundance. India won't cross the demographic threshold for an "old" country -- a median age of 41 -- until the late 2050s, while China reaches that point now. India requires 10.4% sustained GDP growth over 35 years to become rich before aging, compared to China's needed 32% annual growth rate. India's working-age population will increase from 67.5% in 2021 to 69.2% by 2031, with the median age remaining at 34.5 in 2036. The report adds: China's compressed dilemma mirrors what is gripping the developed world, where Europe's share of population over 65 is on track to hit 30% by 2050, up from 8% in 1950. Raising retirement ages -- what economists describe as the closest thing to a silver bullet -- faces older voting blocs, who now make up roughly 40% of those who turn up at the polls in European elections. In the U.S., what J.P. Morgan analysts term a "Social Security cliff" looms by 2033, when the system's trust funds are projected to be exhausted, and hopes that productivity miracles (powered by, hopefully AI) will quietly square this circle look optimistic, leaving much of the rich world and North Asia out of time.

An anonymous reader shares a report: After years of research, the Wyoming Stable Token Commission has unveiled the mainnet launch of its first official state-backed stablecoin. The so-called Frontier Stable Token (FRNT), marking the first time a U.S. state has issued a blockchain-based, fiat-pegged token meant to be used by retail and enterprises alike, according to an announcement on Tuesday.

"FRNT is designed to provide secure, transparent, and efficient digital transactions for individuals, businesses, and institutions -- worldwide," the commission wrote in a statement. "This groundbreaking initiative cements Wyoming at the forefront of digital finance and blockchain innovation."

Indeed, the Cowboy State has long been ahead of the curve when it comes to crypto regulation, including in recognizing DAOs as legal entities, creating a framework for "crypto-banks" under the Special Purpose Depository Institutions charter, and passing the state's Stable Token Act -- all meant to draw economic activity to the region.

Global fertility rates have fallen from five children per woman in the mid-twentieth century to 2.2 today, with approximately half of countries now below the 2.1 replacement threshold, according to data from the Institute for Health Metrics and Evaluation at the University of Washington.

Mexico's rate dropped from seven children in 1970 to 1.6 in 2023. South Korea recorded 0.75 in 2024, down from 4.5 in 1970. The IHME projects over three-quarters of countries will fall below replacement level by 2050. A UN survey of 14,000 people across 14 countries found 39% cited financial limitations as a primary reason for not having children. China's population peaked around 2022 at 1.4 billion, while the U.S. Census Bureau predicts America's population will peak in 2080 at 370 million.

Epic Games CEO Tim Sweeney told the Financial Times that the UK Competition and Markets Authority's December decision to delay mandating alternative app stores on iPhones was a "blunder" that leaves Britain "well behind" other jurisdictions.

The CMA postponed until next year whether to require Apple to allow third-party app stores or sideloading, unlike the EU's Digital Markets Act. Fortnite remains unavailable on UK iOS devices following Epic's years-long dispute over Apple's 30% commission fees. The regulator said it would prioritize forcing Apple and Google to allow alternative payment systems.

The U.S. Federal Trade Commission sued ticket reseller Key Investment Group for evading purchasing limits to buy up thousands of tickets to live events including Taylor Swift's Eras tour and resell them at a markup, according to a complaint filed in Maryland federal court on Monday. From a report: The Baltimore, Maryland-based company, which operates ticket resale sites including TotalTickets.com, used thousands of Ticketmaster accounts, including fake or purchased accounts, the FTC said.

Ticketmaster faced intense criticism after its botched 2022 sale of tickets to Swift's much-hyped Eras tour, when billions of requests from Swift fans, bots and ticket resellers overwhelmed its website and the company canceled a planned ticket sale to the general public.

For one Swift concert in Las Vegas in March 2023, Key Investment Group and its affiliates used 49 different accounts to purchase 273 tickets and evade a 6-ticket purchase limit, netting more than $119,000 in revenue on resales, the FTC said on Monday. The company made more than $1.2 million reselling 2,280 Swift concert tickets it purchased in 2023, the agency said.

The UK government has agreed to withdraw its order requiring Apple to create backdoor access to encrypted iCloud data following intervention from the Trump administration. Vice President JD Vance negotiated the agreement during his recent UK holiday after the January order issued under the UK Investigatory Powers Act prompted Apple to pull its iCloud Advanced Data Protection service from Britain in February. Director of National Intelligence Tulsi Gabbard said the UK agreed to drop demands for access to "the protected encrypted data of American citizens." Apple had filed a complaint with the Investigatory Powers Tribunal scheduled for hearing early next year.

England has declared a "nationally significant" water shortage as reservoirs dropped to 67.7% capacity, their lowest levels in at least a decade. The UK Centre for Ecology and Hydrology warned of exceptionally low river flows while groundwater continues dwindling across the country. Hosepipe bans now affect all of England, with additional restrictions probable in coming months.

Water companies lose approximately one trillion litres annually through leaky pipes -- 20% of all treated water -- while the annual pipe replacement rate remains at 0.05%. No new reservoir has been built in 30 years despite population growth. Government forecasts project England's public water supply could fall short by 5 billion litres daily by 2055 without urgent infrastructure investment. The economic cost of water scarcity could reach $11.48 billion over this parliament, according to thinktank Public First.

Trading volume on AI prediction markets reached approximately $20 million this month across platforms including Kalshi and Polymarket. Kalshi reports ten times the AI trading volume compared to early 2025.

Bettors place wagers on outcomes including monthly AI model rankings, federal AI regulation prospects, and Sam Altman's potential OpenAI equity stake.

Wikipedia volunteer Grnrchst uncovered a decade-long campaign that created articles about composer David Woodard in 335 languages. The investigation identified 200 accounts and IP addresses systematically creating Woodard articles across 92 languages between 2017 and 2019, averaging one new article every six days. From December 2021 through June 2025, 183 unique accounts each created a single Woodard article in different languages after establishing credibility through unrelated edits.

Wikipedia stewards removed 235 articles from smaller wikis. Larger Wikipedia communities banned numerous accounts and deleted 80 additional articles. Twenty Woodard articles remain. Grnrchst called it "the single largest self-promotion operation in Wikipedia's history."

EV sales are up 27% for the first seven months of 2025 — for the world. But in America "For the first half of 2025, EV registrations rose 7% to 620,642, with market share inching up just 0.1 percentage point to 7.5 percent," reports Automotive News.

America's new EV registrations were up 4.6% in June (compared to June of 2024), "But EV market share fell for the month and stayed flat for the first half of the year, according to the most recent S&P Global Mobility data." June's 113,460 EV registrations represented 8.6% of U.S. light-vehicle market share, down from 8.8% a year earlier... The data, which serves as a sales proxy since some EV makers don't report U.S. numbers, shows continued flattening of EV market share ahead of the Sept. 30 repeal of the $7,500 federal tax credit.

The S&P Global Mobility numbers include only battery-electric vehicles and not hybrids.
In June Tesla led with 57,260 registrations — more than 6x its next competitor. (Although Tesla's share of the EV segment dropped 6.8% to 43.7 percent in the first half of 2025).

Ranking #2 in June registrations was Chevrolet with 9,517 — a 152% gain over Chevrolet's June 2024 registrations. (Pointing out that the Chevy Equinox EV starts at under $35,000, Electrek writes that "America's most affordable EV with over 315 miles of range, as GM calls it, is quickly winning over buyers.") Automotive News reports Equinox EV registrations surged 722% to 6,239 in June, with Chevy's share of the EV segment more than doubling to 7.7%.

Chevy pulled ahead of Ford (5,759 registrations), Hyundai (5,227 registrations), Rivian (4,613 registrations) and Cadillac (4,121 registrations). Although maybe it's just as interesting that the complete chart shows electric vehicle registrations for 33 different automakers...

From the French newspaper Le Monde: Odorless, quiet, sustainable. On the last day of July, passengers boarded Barcelona's V3 bus line with no idea where its fuel came from. Written in large letters on the bus facade, just below its name "Nimbus," a sign clearly stated: "This bus runs on biomethane produced from eco-factory sludge." Still, the explanation was likely too vague for most to grasp its full meaning. The moist matter from wastewater treated at the Baix Llobregat treatment plant was used to produce the biomethane. In other words: the human waste of more than 1.5 million residents of the Catalan city.

"Illinois last week banned the use of artificial intelligence in mental health therapy," reports the Washington Post, "joining a small group of states regulating the emerging use of AI-powered chatbots for emotional support and advice." Licensed therapists in Illinois are now forbidden from using AI to make treatment decisions or communicate with clients, though they can still use AI for administrative tasks. Companies are also not allowed to offer AI-powered therapy services — or advertise chatbots as therapy tools — without the involvement of a licensed professional.

Nevada passed a similar set of restrictions on AI companies offering therapy services in June, while Utah also tightened regulations for AI use in mental health in May but stopped short of banning the use of AI.

The bans come as experts have raised alarms about the potential dangers of therapy with AI chatbots that haven't been reviewed by regulators for safety and effectiveness. Already, cases have emerged of chatbots engaging in harmful conversations with vulnerable people — and of users revealing personal information to chatbots without realizing their conversations were not private.

Some AI and psychiatry experts said they welcomed legislation to limit the use of an unpredictable technology in a delicate, human-centric field.

Matt Asay answered questions from Slashdot readers in 2010 as the then-COO of Canonical. Today he runs developer marketing at Oracle (after holding similar positions at AWS, Adobe, and MongoDB).

And this week Asay contributed an opinion piece to InfoWorld reminding us of open source contributions from companies where "enlightened self-interest underwrites the boring but vital work — CI hardware, security audits, long-term maintenance — that grassroots volunteers struggle to fund." [I]f you look at the Linux 6.15 kernel contributor list (as just one example), the top contributor, as measured by change sets, is Intel... Another example: Take the last year of contributions to Kubernetes. Google (of course), Red Hat, Microsoft, VMware, and AWS all headline the list. Not because it's sexy, but because they make billions of dollars selling Kubernetes services... Some companies (including mine) sell proprietary software, and so it's easy to mentally bucket these vendors with license fees or closed cloud services. That bias makes it easy to ignore empirical contribution data, which indicates open source contributions on a grand scale.
Asay notes Oracle's many contributions to Linux: In the [Linux kernel] 6.1 release cycle, Oracle emerged as the top contributor by lines of code changed across the entire kernel... [I]t's Oracle that patches memory-management structures and shepherds block-device drivers for the Linux we all use. Oracle's kernel work isn't a one-off either. A few releases earlier, the company topped the "core of the kernel" leaderboard in 5.18, and it hasn't slowed down since, helping land the Maple Tree data structure and other performance boosters. Those patches power Oracle Cloud Infrastructure (OCI), of course, but they also speed up Ubuntu on your old ThinkPad. Self-interested contributions? Absolutely. Public benefit? Equally absolute.

This isn't just an Oracle thing. When we widen the lens beyond Oracle, the pattern holds. In 2023, I wrote about Amazon's "quiet open source revolution," showing how AWS was suddenly everywhere in GitHub commit logs despite the company's earlier reticence. (Disclosure: I used to run AWS' open source strategy and marketing team.) Back in 2017, I argued that cloud vendors were open sourcing code as on-ramps to proprietary services rather than end-products. Both observations remain true, but they miss a larger point: Motives aside, the code flows and the community benefits.

If you care about outcomes, the motives don't really matter. Or maybe they do: It's far more sustainable to have companies contributing because it helps them deliver revenue than to contribute out of charity. The former is durable; the latter is not.
There's another practical consideration: scale. "Large vendors wield resources that community projects can't match."

Asay closes by urging readers to "Follow the commits" and "embrace mixed motives... the point isn't sainthood; it's sustainable, shared innovation. Every company (and really every developer) contributes out of some form of self-interest. That's the rule, not the exception. Embrace it." Going forward, we should expect to see even more counterintuitive contributor lists. Generative AI is turbocharging code generation, but someone still has to integrate those patches, write tests, and shepherd them upstream. The companies with the most to lose from brittle infrastructure — cloud providers, database vendors, silicon makers — will foot the bill. If history is a guide, they'll do so quietly.

Puerto Rico expects 93 different power outages this summer, reports the Washington Post.

But they also note that "roughly 1 in 10 Puerto Rican homes now have a battery and solar array for backup power" which have also "become a crucial source of backup power for the entire island grid." A network of 69,000 home batteries can generate as much electricity as a small natural gas turbine during an emergency, temporarily covering about 2 percent of the island's energy needs when things go wrong... "It has very, very certainly prevented more widespread outages," said Daniel Haughton, [transmission and distribution planning director for Puerto Rico's grid operator]. "In the instances that we had to [cut power], it was for a much shorter duration: A four-hour outage became a one- or two-hour outage."

Puerto Rico's experience offers a glimpse into the future for the rest of the United States, where batteries are starting to play a big role in keeping the lights on. Authorities in Texas, California and New England have credited home batteries with preventing blackouts during summer energy crunches. As power grids across the country groan under the increasing strain of new data centers, factories and EVs, batteries offer a way for homeowners to protect themselves — and all of their neighbors — from the threat of outages. Batteries have been booming in the U.S. since 2022, when Congress created generous installation tax credits for homeowners and power companies.

Home batteries generally come as an option alongside rooftop solar panels, according to Christopher Rauscher, head of grid services and electrification for Sunrun, a company that installs both. More than 70 percent of the people who hire Sunrun to put up solar panels also get a battery. With the tax credits — and the money saved on rising electricity costs — solar panels and batteries make financial sense for most American homes, according to a study Stanford University scientists published Aug. 1. About 60 percent of homes would save money in the long run with solar panels and batteries...

Those batteries can have broader benefits, too. Utilities pay customers hundreds of dollars a year to sign their batteries up to form "virtual power plants," which send electricity to the grid whenever power plants can't keep up with demand. California's network of home batteries can now add 535 megawatts of electricity in an emergency — about half as much energy as a nuclear power plant... [H]omeowners can make thousands of dollars a year lowering their energy bills, selling solar power back to the grid or enrolling their batteries in a virtual power plant, depending on their power company's policies and state regulations. "Over time, you would get the full payback for your system and basically get your backup for free," said Ram Rajagopal, an associate professor of civil and environmental engineering who co-authored the Stanford study.
