America's CIA Recruited Iran's Nuclear Scientists - By Threatening To Kill Them (newyorker.com) 126

A former U.S. spy spoke to The New Yorker about "years of clandestine work for the C.I.A. — which, he said, had 'prevented Iran from getting a nuke'." [Kevin] Chalker told me that, as he understood it, the Pentagon had suggested running commando operations to kill key Iranian scientists, as Israel subsequently did. But the C.I.A. proposed recruiting those scientists to defect, as U.S. spies had once courted Soviet physicists. Chalker paraphrased the agency's pitch: "We can debrief them and learn so much more — and, if they say no, then you can kill them." (A more senior agency official confirmed the broad strokes of his account.) The White House liked the agency's idea, and [president George W.] Bush authorized the C.I.A. to conduct clandestine operations to stop Iran from building a bomb. The C.I.A. program that Chalker described to me became publicly known in 2007, when the Los Angeles Times reported on the existence of an agency project called Brain Drain. But the details of the "invitations" to Iranian scientists have not previously been reported...

Chalker typically had about ten minutes to explain, as gently as possible, that he was from the C.I.A., that he had the power to secure the scientist and his family a comfortable new life in the U.S. — and that, if the offer was rejected, the scientist, regrettably, would be assassinated. (Chalker tried to emphasize the happier potential outcome.) Killing a civilian scientist would violate international law. The American government has denied ever doing it, and I found no evidence that the U.S. has carried out any such murders. A former senior agency official familiar with the Brain Drain project told me all that mattered was that Iranian scientists had believed they would be killed, regardless of whether the U.S. actually made good on the threat. And Israel had been conducting a campaign to assassinate Iranian scientists, which made the prospect of lethal reprisal highly plausible. Other former officials with knowledge of the project told me that the C.I.A. sometimes shared intelligence with Mossad which enabled its operatives to locate and kill a scientist. Such information exchanges were kept vague enough to preserve deniability if a more legalistic U.S. Administration later took office...

[Chalker] is confident that those who rebuffed him were, in fact, killed — one way or another... One of Chalker's colleagues told me that, against the backdrop of so many Israeli assassinations, Chalker's interactions with Iranian scientists could almost be considered humanitarian — he had been "throwing them a lifeline." Of the many scientists he approached, three-quarters ultimately agreed to coöperate.

Their 10,000-word article suggests Chalker may now be resentful the CIA didn't help him in a later unrelated lawsuit, noting it's "nearly unheard of for ex-spies to divulge their past activities."

But Chalker also says he "helped obtain pivotal information that laid the groundwork for more than a decade of American efforts to disrupt the Iranian nuclear-weapons program, from the Stuxnet cyberattacks, which occurred around 2010 [destroying 1,000 uranium-enriching centrifuges], to the Obama Administration's nuclear deal, in 2015, to the U.S. air strikes on Iranian atomic-energy facilities in the summer of 2025."

Renewables Reached Nearly 50% of Global Electricity Capacity Last Year (theregister.com) 114

Renewables made up nearly half of global installed electricity capacity by the end of 2025, "accounting for 85.6% of global capacity expansion," reports the Register, citing the International Renewable Energy Agency's (IRENA) 2026 Renewable Capacity Statistics report. "Per IRENA's data, that aforementioned 85.6 percent share of new power capacity additions was actually a decrease from 2024, when renewables were about 92 percent of global capacity additions. Yes, the share of total installed power capacity in 2025 rose again, but non-renewable capacity additions also rebounded sharply last year." From the report: Solar, in turn, was the dominant renewable technology, accounting for nearly three-quarters of last year's renewable capacity additions. Those additions totaled 692 GW in 2025, lifting installed renewable capacity by a record 15.5 percent year over year, IRENA noted. By the end of last year, renewables accounted for 49.4 percent of global installed electricity capacity, while variable renewable sources such as solar and wind represented roughly 35 percent of total capacity. For reference, it was only in 2023 that renewable energy sources crossed the threshold of generating 30 percent of the world's electricity.

Goldman Sachs, Morgan Stanley Calculate AI's Contribution To U.S. Growth May Be Basically Zero 30

The narrative that AI spending has been singlehandedly propping up the U.S. economy -- a claim that captivated Silicon Valley, Wall Street and Washington over the past year -- is facing serious pushback from economists [non-paywalled source] at Goldman Sachs, Morgan Stanley and JPMorgan Chase, all of whom now calculate that the AI buildup's direct contribution to growth was dramatically overstated and possibly close to zero.

The debate hinges on how GDP accounts for imported components: roughly three-quarters of AI data center costs go toward computer chips and gear largely manufactured in Asia, and that spending gets subtracted from domestic output because it boosts foreign economies. Joseph Politano of the Apricitas Economics newsletter pegs AI's actual contribution at about 0.2 percentage points of the 2.2 percent U.S. growth in 2025, and even Hannah Rubinton at the St. Louis Fed -- whose own analysis attributed 39 percent of growth to AI-related business spending through the first nine months of the year -- acknowledges that figure is probably the ceiling. "It's not like AI is propping up the economy," Rubinton said.

Hazardous Substances Found In All Headphones Tested By ToxFREE Project (theguardian.com) 95

An anonymous reader quotes a report from the Guardian: You wear them at work, you wear them at play, you wear them to relax. You may even get sweaty in them at the gym. But an investigation into headphones has found every single pair tested contained substances hazardous to human health, including chemicals that can cause cancer, neurodevelopmental problems and the feminization of males. [...] Researchers say that while individual doses from particular sources may be low, a "cocktail effect" of daily, multi-source exposure nevertheless poses potentially severe long-term risks to health. [...]

Researchers bought 81 pairs of in-ear and over-ear headphones, either on the market in the Czech Republic, Slovakia, Hungary, Slovenia and Austria, or from the online marketplaces Shein and Temu, and took them for laboratory analysis, testing for a range of harmful chemicals. "Hazardous substances were detected in every product tested," they said. Bisphenol A (BPA) appeared in 98% of samples, and its substitute, bisphenol S (BPS), was found in more than three-quarters. Synthetic chemicals used to stiffen plastic, BPA and BPS mimic the action of oestrogen inside organisms, causing a range of adverse effects including the feminization of males, early onset puberty in girls, and cancer. Previous studies have shown that bisphenols can migrate from synthetic materials into sweat, and that they can be absorbed through the skin.

"Given the prolonged skin contact associated with headphone use, dermal exposure represents a relevant pathway, and it is reasonable to assume that similar migration of BPA and its substitutes may occur from headphone components directly to the user's skin," the researchers said. Also found in the headphones tested were phthalates, potent reproductive toxins that can impair fertility; chlorinated paraffins, which have been linked to liver and kidney damage; and brominated and organophosphate flame retardants, which have similar endocrine disrupting properties to bisphenols. Most were, however, found in only trace quantities.

Comcast Keeps Losing Customers Despite Price Guarantee, Unlimited Data (arstechnica.com) 79

Comcast's attempt to slow broadband customer losses still isn't stopping the bleeding as fiber and fixed wireless competition intensifies. In Q4 2025 alone, Comcast lost 181,000 broadband subscribers, even as it leans harder into wireless bundling and other business lines like Peacock and theme parks. Ars Technica reports: The Q4 net loss is more than the 176,000 loss predicted by analysts, although not as bad as the 199,000-customer loss that spurred [Comcast President Mike Cavanagh's] comment about Comcast "not winning in the marketplace" nine months ago. The Q4 2025 loss reported today is also worse than the 139,000-customer loss in Q4 2024 and the 34,000-customer loss in Q4 2023.

"Subscriber losses were 181,000, as the early traction we are seeing from our new initiatives was more than offset by continued competitive intensity," Comcast CFO Jason Armstrong said during an earnings call today, according to a Motley Fool transcript. Comcast's residential broadband customers dropped to 28.72 million, while business broadband customers dropped to 2.54 million, for a total of 31.26 million.

Armstrong said that average revenue per user grew 1.1 percent, "consistent with the deceleration that we had previewed reflecting our new go-to-market pricing, including lower everyday pricing and strong adoption of free wireless lines." Armstrong expects average revenue per user to continue growing slowly "for the next couple of quarters, driven by the absence of a rate increase, the impact from free wireless lines, and the ongoing migration of our base to simplified pricing." Comcast Connectivity & Platforms chief Steve Croney said the firm is facing "a more competitive environment from fiber" and continued competition from fixed wireless. "The market is going to remain intensely competitive," he said.

Wall Street Pushes Solo 401(k)s as More Americans Work for Themselves (bloomberg.com) 22

An anonymous reader shares a report: A niche retirement plan favored by freelancers is quickly becoming a hot Wall Street sales pitch, as more and more Americans look for ways to shelter a bigger chunk of their paychecks from taxes. Known as solo 401(k)s, they allow the self-employed to contribute $72,000 a year into tax-advantaged retirement accounts. That's nearly three times the maximum for typical salaried workers in the US.

While they've existed for decades serving a workforce that often struggled to earn enough to max out those contributions, wealth planners like JPMorgan Chase & Co. and Betterment are now racing to tap into burgeoning demand from a newer, and wealthier cohort: Post-pandemic contractors and self-employed DIY savers looking to shelter more income, grow assets tax-deferred or tax-free, all with the click of a button.

The pitch is simple: Because of a quirk in the tax code, self-employed workers effectively contribute twice to their 401(k)s -- once as an employee on their own behalf and then again as a business owner making matching contributions. The platforms take care of the paperwork and clients get institutional-level tax planning and investment flexibility.
More than three-quarters of America's record 36 million small businesses now have just a single employee, the owner. Cerulli Associates projects that total 401(k) plans in the U.S. will surpass 1 million by 2030, and the fastest growth is expected in sub-$5 million "micro" accounts.

Apple is Fighting for TSMC Capacity as Nvidia Takes Center Stage (culpium.com) 47

Apple, which spent years as TSMC's undisputed top customer and helped the Taiwanese foundry become the semiconductor industry's most important manufacturer, is now fighting for production capacity as Nvidia's AI chip orders consume an ever-larger share of the company's leading-edge wafer supply.

TSMC CEO CC Wei visited Cupertino last August to deliver unwelcome news: Apple would face the largest price increase in years and the iPhone maker would no longer have guaranteed access to production capacity across TSMC's nearly two dozen fabs.

According to Culpium analysis and its supply chain sources, Nvidia likely overtook Apple as TSMC's largest customer in at least one or two quarters of 2025. TSMC's revenue climbed 36% last year to $122 billion, the company reported Thursday.

AI Fails at Most Remote Work, Researchers Find (msn.com) 39

A new study "compared how well top AI systems and human workers did at hundreds of real work assignments," reports the Washington Post.

They add that at least one example "illustrates a disconnect three years after the release of ChatGPT that has implications for the whole economy." AI can accomplish many impressive tasks involving computer code, documents or images. That has prompted predictions that human work of many kinds could soon be done by computers alone. Bentley University and Gallup found in a survey [PDF] last year that about three-quarters of Americans expect AI to reduce the number of U.S. jobs over the next decade. But economic data shows the technology largely has not replaced workers.

To understand what work AI can do on its own today, researchers collected hundreds of examples of projects posted on freelancing platforms that humans had been paid to complete. They included tasks such as making 3D product animations, transcribing music, coding web video games and formatting research papers for publication. The research team then gave each task to AI systems such as OpenAI's ChatGPT, Google's Gemini and Anthropic's Claude. The best-performing AI system successfully completed only 2.5 percent of the projects, according to the research team from Scale AI, a start-up that provides data to AI developers, and the Center for AI Safety, a nonprofit that works to understand risks from AI. "Current models are not close to being able to automate real jobs in the economy," said Jason Hausenloy, one of the researchers on the Remote Labor Index study...

The results, which show how AI systems fall short, challenge predictions that the technology is poised to soon replace large portions of the workforce... The AI systems failed on nearly half of the Remote Labor Index projects by producing poor-quality work, and they left more than a third incomplete. Nearly 1 in 5 had basic technical problems such as producing corrupt files, the researchers found.

One test involved creating an interactive dashboard for data from the World Happiness Report, according to the article. "At first glance, the AI results look adequate. But closer examination reveals errors, such as countries inexplicably missing data, overlapping text and legends that use the wrong colors — or no colors at all."

The researchers say AI systems are hobbled by a lack of memory, and are also weak on "visual" understanding.

Reddit Surges in Popularity to Overtake TikTok in the UK - Thanks to Google's Algorithm? (theguardian.com) 38

Reddit "has overtaken TikTok as Britain's fourth most-visited social media service," reports the Guardian: The platform has undergone huge growth over the last two years, with an 88% increase in the proportion of UK internet users it reaches. Three in five Brits online now encounter the site, up from a third in 2023, according to Ofcom. Its popularity is rising fastest with younger internet users. It is now the sixth most visited organisation of any kind by UK users aged between 18 and 24, up from 10th a year earlier. More than three-quarters of that cohort now visit it....

The UK is a boom market for the platform, with the second largest user base behind the US, according to company records. A series of factors are behind its rise. However, a change in Google's search algorithms last year to prioritise helpful content from discussion forums appears to have been a significant driver. A recent deal with Google that allows the company to train its AI model on Reddit's content also appears to have provided a boost. Reddit is the most-cited source for Google AI overviews, which is likely to see more people directed to its forums. It has a similar deal with OpenAI, which owns the most popular AI chatbot, ChatGPT.

According to the article, Reddit "believes it is also benefiting from shifting internet habits, as younger users seek out human-generated reviews and opinions."

'One of America's Most Successful Experiments Is Coming to a Shuddering Halt' (nytimes.com) 282

The six-decade flow of highly skilled Indian immigrants to the United States -- a migration pattern that produced some of the country's highest-earning households, several Nobel laureates, and the CEOs of Google, Microsoft, and Pepsi -- appears to be grinding to a halt amid rising anti-Indian rhetoric from Republican officials and chaos in the visa system, according to New York Times.

Indian student arrivals at American universities fell 44% this year, even as Indians had just become the largest contingent of foreign students the previous year. The decline comes as top Trump administration officials have publicly accused Indian immigrants of gaming the system. Stephen Miller, the architect of the president's immigration crackdown, declared on Fox News that Indians "engage in a lot of cheating on immigration policies that is very harmful to American workers." Governor Ron DeSantis called the H-1B visa program "chain migration run amok."

The hostility extends beyond policy circles. At a Hindu temple in Sugar Land, Texas, conservative Christian protesters gathered during the dedication of a 90-foot Hanuman statue, calling the deity "a demon god." A U.S. Senate candidate wrote on social media: "Why are we allowing a false statue of a false Hindu God to be here in Texas? We are a CHRISTIAN nation." Indian Americans' median household income significantly outstrips that of white Americans, and about three-quarters hold at least a college degree. Foreign students have earned more engineering and computer science doctorates than American citizens and permanent residents for over two decades, according to the National Science Foundation. American tech giants have announced $67.5 billion in new investments in India in just the past few months.

Tough Job Market Has People Using Dating Apps To Get Interviews 42

An anonymous reader quotes a report from Bloomberg: Most people use dating apps to find love. Tiffany Chau used one to hunt for a summer internship. This fall, the 20-year-old junior at California College of the Arts tailored her Hinge profile to connect with people who could offer job referrals or interviews. One match brought her to a Halloween party, where she networked in hopes of landing a product-design internship for the summer. While there, she got some tips from someone who had recently interviewed at Accenture. As for the connection with her date? Not so much. "I feel like my approach to the dating apps is it being another networking platform like everything else, like Instagram or LinkedIn," Chau said.

Chau is among a cadre of workers who are using dating apps to boost their job searches. They're recognizing that the online job hunt is broken as unemployed workers flood the system, AI screens out resumes and many job matching programs are overwhelmed. Automation has squeezed human contact out of hiring, which has pushed applicants to seek any path to a live hiring manager, no matter the means.

The overall US unemployment rate continued to climb throughout 2025, reaching 4.6%, according to the Bureau of Labor Statistics. And while the number of unemployed high school graduates held steady at about 4.4% in November, the rate for workers with a bachelor's degree rose to 2.9% from 2.5% a year ago. About a third of dating app users said they had sought matches for job hook-ups, according to a ResumeBuilder.com survey of about 2,200 US dating site customers in October. Two-thirds targeted potential paramours who worked at a desirable employer. Three-quarters said they matched with people working in roles they wanted.
"People are doing it to expand their networks, make connections, because the best way to get a job today is who you know," said Stacie Haller, ResumeBuilder.com's chief career advisor. "Networking is the only way people are rising above the horror show that the job search is today."

There Was Some Good News on Green Energy in 2025 (msn.com) 40

Yes, greenhouse gas emissions kept rising in 2025, writes Bloomberg (alternate URL here). And the pledges of various governments to lower greenhouse gases "are nowhere near where they need to be to avoid catastrophic climate change..."

But in 2025, "there were silver linings too." The world is decarbonizing faster than was expected 10 years ago and investment into the clean energy transition, including everything from wind and solar to batteries and grids, is expected to have reached a new record of $2.2 trillion globally in 2025, according to research by the Energy & Climate Intelligence Unit, a London nonprofit. "Is this enough to keep us safe? No it clearly isn't," said Gareth Redmond-King, international lead at the ECIU. "Is it remarkable progress compared to where we were headed? Clearly it is...." Global investment in clean tech far outpaced what went into polluting industries. For every $1 funding fossil fuel projects, $2 went into clean power, according to the ECIU. For China, the EU, the U.S. and India, the four largest polluters, it was $2.60.

Funds flowing into renewable power set another record in the first half of this year and were up 10% compared to the same period in 2024, to $386 billion, according to the latest available research by BloombergNEF. Solar and wind grew fast enough to meet all new electricity demand globally in the first three quarters of 2025, according to UK-based energy think tank Ember. That means renewable capacity is set to hit a new record globally this year, with Ember forecasting an 11% increase from 2024. Over the last three years, renewable capacity grew by nearly 30% on average. That puts the world within reach of the goal set at COP 28 in Dubai in 2023 to triple clean power by 2030. China is leading the charge, with the world's largest polluter expected to have delivered 66% of new solar capacity, and 69% of new wind globally this year, according to Ember. Renewables also advanced in parts of Asia, Europe and South America.

The explosive power demand from artificial intelligence is also turning the tide on green technology investment, which had soured in recent years. For the first three quarters of this year, global clean tech investment, which was dominated by funding in next-generation nuclear reactors, renewables and other solutions that help power data centers, has already surpassed all of 2024. That marks the sector's first annual increase since the 2022 peak. And despite President Trump's rollback of climate policies, the S&P's main gauge tracking clean energy is up about 50% this year, outperforming most other stock indexes and even gold. That same enthusiasm has also helped channel more capital into developing and upgrading the power grid, a backbone of the global energy transition.

The article also notes that prices per kilowatt-hour of battery capacity "fell by 8% to a record $108 this year and they're expected to decline a further 3% next year, according to BloombergNEF."

And this year the International Court of Justice "determined that countries risk being in violation of international law if they don't work toward keeping global warming to the 1.5C threshold agreed on at the Paris climate conference in 2015."

Free Software Foundation Receives 'Historic' Donations Worth Nearly $900K - in Monero (fsf.org) 24

On Wednesday (Christmas Eve), the Free Software Foundation announced it had received two major contributions totaling around $900,000 USD — in the cryptocurrency Monero.

The two donations "are among some of the largest private gifts ever made to the organization," the FSF said in a statement.

"The donors wish to remain anonymous," according to the FSF's statement: The organization is in its annual winter fundraising drive, currently at three-quarters of its $400,000 USD winter goal, and will now switch its focus to a member drive thanks in part to these donations... The donation will support the organization's technical team and infrastructure capacity, as well as strengthen its campaigns, education, licensing, and advocacy initiatives, and future opportunities. The FSF is seeking donations until year-end after which they aim to gain 100 associate members through its year-end fundraising ending January 16.
The FSF's executive director said the donations prove "that software freedom is recognized more and more as a principal issue today, at the core of several other social movements people care about like privacy, ownership, and the right to repair...

"We are proudly supported by a large variety of contributors who care about digital rights. All donations matter, whether $5 or $500,000."

What Rules Govern Hallmark Christmas Movies? (stephenfollows.com) 42

Hallmark has released more than 300 Christmas-themed TV movies since 2000, and a detailed internal rulebook obtained by film data analyst Stephen Follows explains how the company manages to produce nearly one new holiday film per week during the final quarter of each year without the whole operation collapsing into creative chaos.

The document, referred to as Hallmark's "bible" by writers and producers who have worked on these films, specifies everything from script length (105-110 pages across a rigid nine-act structure) to prohibited activities (no bowling, no karaoke). Christmas movies must include snow or its remnants and feature characters engaged in seasonal activities like baking cookies, ice skating, and drinking hot chocolate.

The target demographic is women aged 25-54, and the content must be watchable by an 80-year-old grandmother and a 5-year-old niece simultaneously. The economics differ sharply from theatrical filmmaking. Licensed titles from outside production companies carry budgets around $500,000 or less, while Hallmark's in-house productions can exceed $2 million. About three-quarters of the library comes from external producers. The formula appears to work. Hallmark TV movies have averaged a 6.3 IMDb user score over the past 14 years, compared to 5.9 for feature films worldwide.

In 2025 Scammers Have Stolen $835M from Americans Using Fake Customer Service Numbers (straitstimes.com) 26

They call it "the business-impersonator scam". And it's fooled 396,227 Americans in just the first nine months of 2025 — 18% more than the 335,785 in the same nine months of 2024. That's according to a Bloomberg reporter (who also fell for it in late November), citing the official statistics from America's Federal Trade Commission: Some pose as airline staff on social media and respond to consumer complaints. Others use texts or e-mails claiming to be an airline reporting a delayed or cancelled flight to phish for travellers' data. But the objective is always the same: to hit a stressed out, overwhelmed traveller at their most vulnerable. In my case, the scammer exploited weaknesses in Google's automated ad-screening system, so that fraudulent sponsored results rose to the top [They'd typed "United airlines agent on demand" into Google, and the top search result on their phone said United.com, had a 1-888 number next to it and said it had had 1M+ visits in past month. "It looked legit. I tapped the number..." ]

After I reported the fake "United Airlines" ad to Google, via an online form for consumers, it was taken down. But a few days later, I entered the same search terms and the identical ad featuring the same 1-888 number was back at the top of my results. I reported it again, and it was quickly removed again... A [Google] spokesperson there said the company is constantly evolving its tactics "to stay ahead of bad actors." Of the 5.1 billion ads blocked by the company last year, she said, 415 million were taken down for "scam-related violations." Google updated its ads misrepresentation policy in 2024 to include "impersonating or falsely implying affiliation with a public figure, brand or organization to entice users to provide money or information." Still, many impostor ads slip through the cracks.

"Reported losses from business-impostor scams in the United States rose 30 per cent, to US$835 million, in the first three quarters of 2025," the article points out (citing more figures from the America's Federal Trade Commision). An updated version of the article also includes a response from United Airlines. "We encourage customers to only use customer-service contact information that is listed on our website and app."

And what happened to the scammed reporter? "I called American Express and contested the charge before cancelling my credit card. I then contacted Experian, one of the three major credit bureaus, to put a fraud alert on my file. Next, I filed a complaint with the FTC and reported the fake ad to Google.

"American Express wound up resolving the dispute in my favour, but the memories of this chaotic Thanksgiving will stay with us forever. "

UK Actors Vote To Refuse To Be Digitally Scanned In Pushback Against AI 44

An anonymous reader quotes a report from the Guardian: Actors have voted to refuse digital scanning to prevent their likeness being used by artificial intelligence in a pushback against AI in the arts. Members of the performing arts union Equity were asked if they would refuse to be scanned while on set, a common practice in which actors' likeness is captured for future use -- with 99% voting in favor of the move. The vote was an indicative ballot designed to demonstrate the strength of feeling on the issue, with more than 7,000 members polled on a 75% turnout. However, actors would not be legally protected if they refused to be scanned.

The union said it would write to Pact, the trade body representing the majority of producers and production companies in the UK, to negotiate new minimum standards for pay, as well as terms and conditions for actors working in film and TV. Equity said it may hold a formal ballot depending on the outcome of the negotiations, which, if backed, would give actors legal protection if they were being pressed to accept digital scanning on set.
The general secretary, Paul Fleming, said: "Artificial intelligence is a generation-defining challenge. And for the first time in a generation, Equity's film and TV members have shown that they are willing to take industrial action. Ninety per cent of TV and film is made on these agreements. Over three-quarters of artists working on them are union members. This shows that the workforce is willing to significantly disrupt production unless they are respected, and [if] decades of erosion in terms and conditions begins to be reversed."

How We Ingest Plastic Chemicals While Consuming Food (washingtonpost.com) 67

A comprehensive database built by scientists in Switzerland and Norway has catalogued 16,000 chemicals linked to plastic materials, and the findings paint a troubling picture of what Americans are actually eating when they prepare food in their kitchens. Of those 16,000 chemicals, more than 5,400 are considered hazardous to human health by government and industry standards, while just 161 are classified as not hazardous. The remaining 10,700-plus chemicals simply don't have enough data to determine their safety.

The chemicals enter food through multiple pathways. Black plastic utensils and trays often contain brominated flame retardants because they're made from recycled electronic waste. Nonstick pans and compostable plates frequently contain PFAS. One California study found phthalates in three-quarters of tested foods, and a Consumer Reports analysis last year detected BPA or similar chemicals in 79% of foods tested. According to CDC data, more than 90% of Americans have measurable levels of these chemicals in their bodies. A 10-fold increase in maternal levels of brominated flame retardants is associated with a 3.7-point IQ drop in children.

Startup Successfully Uses AI to Find New Geothermal Energy Reservoirs (cnn.com) 50

A Utah-based startup announced last week it used AI to locate a 250-degree Fahrenheit geothermal reservoir, reports CNN. It'll start producing electricity in three to five years, the company estimates — and at least one geologist believes AI could be an exciting "gamechanger" for the geothermal industry. [Startup Zanskar Geothermal & Minerals] named it "Big Blind," because this kind of site — which has no visual indication of its existence, no hot springs or geysers above ground, and no history of geothermal exploration — is known as a "blind" system. It's the first industry-discovered blind site in more than three decades, said Carl Hoiland, co-founder and CEO of Zanskar. "The idea that geothermal is tapped out has been the narrative for decades," but that's far from the case, he told CNN. He believes there are many more hidden sites across the Western U.S.

Geothermal energy is a potential gamechanger. It offers the tantalizing prospect of a huge source of clean energy to meet burgeoning demand. It's near limitless, produces scarcely any climate pollution, and is constantly available, unlike wind and solar, which are cheap but rely on the sun shining and the wind blowing. The problem, however, has been how to find and scale it. It requires a specific geology: underground reservoirs of hot water or steam, along with porous rocks that allow the water to move through them, heat up, and be brought to the surface where it can power turbines... The AI models Zanskar uses are fed information on where blind systems already exist. This data is plentiful as, over the last century and more, humans have accidentally stumbled on many around the world while drilling for other resources such as oil and gas.

The models then scour huge amounts of data — everything from rock composition to magnetic fields — to find patterns that point to the existence of geothermal reserves. AI models have "gotten really good over the last 10 years at being able to pull those types of signals out of noise," Hoiland said...

Zanskar's discovery "is very significant," said James Faulds, a professor of geosciences at Nevada Bureau of Mines and Geology.... Estimates suggest over three-quarters of US geothermal resources are blind, Faulds told CNN. "Refining methods to find such systems has the potential to unleash many tens and perhaps hundreds of gigawatts in the western US alone," he said... Big Blind is the company's first blind site discovery, but it's the third site it has drilled and hit commercial resources. "We expect dozens, to eventually hundreds, of new sites to be coming to market," Hoiland said.... Hoiland says Zanskar's work shows conventional geothermal still has huge untapped potential.

Same Product, Same Store, but on Instacart, Prices Might Differ (nytimes.com) 56

A study this week has found that shoppers using Instacart are often charged different prices for identical products at the same store at the same time, even when selecting in-store pickup rather than delivery. The Groundwork Collaborative, a progressive policy group, and Consumer Reports organized nearly 200 volunteers across four cities to simultaneously check prices on 20 grocery items. Price differences appeared on nearly three-quarters of the items tested. In one test, more than 40 participants selected the same Safeway in Washington, D.C. and the same brand of eggs. Prices ranged from $3.99 to $4.79 -- a 20% spread. At a Target in North Canton, Ohio, Skippy peanut butter was $2.99 for some shoppers and $3.59 for others. The full 20-item basket varied by about 7% within each store.

An Instacart spokeswoman said retailers on its platform set their own prices and that some run short-term, randomized pricing tests. The company said tests were "never based on personal or behavioral characteristics." Instacart acquired Eversight, an AI-driven pricing optimization company, in 2022. A Target spokesman said the company is not affiliated with Instacart and bears no responsibility for prices on the platform. Safeway and parent company Albertson's declined to comment.

The Inevitable Shape of Cheap Online Retail (indiadispatch.com) 15

Pinduoduo in China, Shopee in Southeast Asia, and Meesho in India operate in markets that could hardly be more different -- an upper-middle-income industrial state, a stitched-together archipelago of under-banked economies, and a country where three-quarters of retail is unorganized and e-commerce penetration sits at about 7% -- yet all three have landed on the same business model.

These platforms run asset-light marketplaces specializing in cheap goods and slow delivery, monetizing through logistics mark-ups, advertising, and installment credit rather than retail margins. Temu and Shein are further variations now expanding in the U.S. and Europe.

The economics are thin for all. Pinduoduo's EBITDA margins on GMV (gross merchandise value) sit in a 0-4% band; Meesho's group-wide EBITDA hovers around break-even. Neither charges commissions on most sales; both earn through logistics mark-ups and advertising. Sponsored listings account for 1-3% of GMV at Indian marketplaces and 4-5% at Alibaba and Pinduoduo.

Credit is the more consequential side business. In India, cash on delivery functions as unofficial credit. Meesho CEO Vidit Aatrey said the customers prefer CoD for its "built-in delay," which effectively makes it "a five-day loan." Geography, income, and regulation were supposed to produce different answers. They produced one: a 3% endgame where e-commerce clips a few points of GMV and relies on attention and credit for profits.
