“There has been a strong correlation between it and the price of TQQQ, an ETF that seeks to achieve daily investment results that correspond to three times (3x) the daily performance of the Nasdaq-100 Index,” [Yardeni wrote in a note]. Yardeni blamed bitcoin’s slide on the GENIUS Act, which was enacted on July 18, saying that the regulatory framework it established for stablecoins eliminated bitcoin’s transactional role in the monetary system. “It’s possible that the rout in bitcoin is forcing some investors to sell stocks that they own,” he added… Traders who used leverage to make crypto bets would need to liquidate positions in the event of margin calls.

Steve Sosnick, chief strategist at Interactive Brokers, also said bitcoin could swing the entire stock market, pointing out that it’s become a proxy for speculation. “As a long-time systematic trader, it tells me that algorithms are acting upon the relationship between stocks and bitcoin,” he wrote in a note on Thursday.

The pipe operator allows function calls to be chained together, which avoids the extraneous variables and nested statements that might otherwise be involved. Pipes tend to make code more readable than other ways to implement serial operations. Anyone familiar with the Unix/Linux command line or programming languages like R, F#, Clojure, or Elixir may have used the pipe operator. In JavaScript, aka ECMAScript, a pipe operator has been proposed, though there are alternatives like method chaining.

Another significant addition is the URI extension, which allows developers to parse and modify URIs and URLs based on both the RFC 3986 and the WHATWG URL standards. Parsing with URIs and URLs â" reading them and breaking them down into their different parts â" is a rather common task for web-oriented applications. Yet prior versions of PHP didn’t include a standards-compliant parser in the standard library. As noted by software developer Tim Düsterhus, the parse_url() function that dates back to PHP 4 doesn’t follow any standard and comes with a warning that it should not be used with untrusted or malformed URLs.

Other noteworthy additions to the language include: Clone With, for updating properties more efficiently; the #[\NoDiscard] attribute, for warning when a return value goes unused; the ability to use static closures and first-class callables in constant expressions; and persistent cURL handles that can be shared across multiple PHP requests.

[P]ublic records and interviews with more than three dozen scientists, investors, legal experts and others familiar with the company reveal an organization advancing rapidly to the brink of being able to press “go” on its planet-cooling plans. Meanwhile, Stardust is seeking U.S. government contracts and quietly building an influence machine in Washington to lobby lawmakers and officials in the Trump administration on the need for a regulatory framework that it says is necessary to gain public approval for full-scale deployment....

The presentation also included revenue projections and a series of opportunities for venture capitalists to recoup their investments. Stardust planned to sign “government contracts,” said a slide with the company’s logo next to an American flag, and consider a “potential acquisition” by 2028. By 2030, the deck foresaw a “large-scale demonstration” of Stardust’s system. At that point, the company claimed it would already be bringing in $200 million per year from its government contracts and eyeing an initial public offering, if it hadn’t been sold already.

[Yedvab] was delighted, he said, not by the money, but what it meant for the project. “We are, like, few years away from having the technology ready to a level that decisions can be taken” — meaning that deployment was still on track to potentially begin on the timeline laid out in the 2023 pitch deck. The money raised was enough to start “outdoor contained experiments” as soon as April, Yedvab said. These would test how their particles performed inside a plane flying at stratospheric heights, some 11 miles above the Earth’s surface… The key thing, he insisted, was the particle was “safe.” It would not damage the ozone layer and, when the particles fall back to Earth, they could be absorbed back into the biosphere, he said. Though it’s impossible to know this is true until the company releases its formula. Yedvab said this round of testing would make Stardust’s technology ready to begin a staged process of full-scale, global deployment before the decade is over — as long as the company can secure a government client. To start, they would only try to stabilize global temperatures — in other words fly enough particles into the sky to counteract the steady rise in greenhouse gas levels — which would initially take a fleet of 100 planes.

That the global temperature would drop is not in question. Britain’s Royal Society… said in a report issued in early November that there was little doubt it would be effective. They did not endorse its use, but said that, given the growing interest in this field, there was good reason to be better informed about the side effects… [T]hat doesn’t mean it can’t have broad benefits when weighed against deleterious climate change, according to Ben Kravitz, a professor of earth and atmospheric sciences at Indiana University who has closely studied the potential effects of solar geoengineering. “There would be some winners and some losers. But in general, some amount of … stratospheric aerosol injection would likely benefit a whole lot of people, probably most people,” he said. Other scientists are far more cautious. The Royal Society report listed a range of potential negative side effects that climate models had displayed, including drought in sub-Saharan Africa. In accompanying documents, it also warned of more intense hurricanes in the North Atlantic and winter droughts in the Mediterranean. But the picture remains partial, meaning there is no way yet to have an informed debate over how useful or not solar geoengineering could be…

And then there’s the problem of trying to stop. Because an abrupt end to geoengineering, with all the carbon still in the atmosphere, would cause the temperature to soar suddenly upward with unknown, but likely disastrous, effects… Once the technology is deployed, the entire world would be dependent on it for however long it takes to reduce the trillion or more tons of excess carbon dioxide in the atmosphere to a safe level…

Stardust claims to have solved many technical and safety challenges, especially related to the environmental impacts of the particle, which they say would not harm nature or people. But researchers say the company’s current lack of transparency makes it impossible to trust.

The company plans to test the product with a small group of Facebook users in select cities such as New York and San Francisco, according to a person familiar with the project who spoke on the condition of anonymity to discuss private company matters…

Meta’s foray into pushing updates for consumers follows years of controversy over its relationship with publishers. The tech company has waffled between prominently featuring content from mainstream news sources on Facebook to pulling news links altogether as regulators pushed the tech giant to pay publishers for content on its platforms. More recently, publishers have sued Meta, alleging it infringed on their copyrighted works to train its AI models.

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our understanding of dark energy, the elusive force that counters the inward pull of gravity in our universe…

Last year, a consortium of hundreds of researchers using data from the Dark Energy Spectroscopic Instrument (DESI) in Arizona, developed the largest ever 3D map of the universe. The observations hinted at the fact that dark energy may be weakening over time, indicating that the universe’s rate of expansion could eventually slow. Now, a study published November 6 in the journal Monthly Notices of the Royal Astronomical Society provides further evidence that dark energy might not be pushing on the universe with the same strength it used to. The DESI project’s findings last year represented “a major, major paradigm change … and our result, in some sense, agrees well with that,” said Young-Wook Lee, a professor of astrophysics at Yonsei University in South Korea and lead researcher for the new study....

To reach their conclusions, the researchers analyzed a sample of 300 galaxies containing Type 1a supernovas and posited that the dimming of distant exploding stars was not only due to their moving farther away from Earth, but also due to the progenitor star’s age… [Study coauthor Junhyuk Son, a doctoral candidate of astronomy at Yonsei University, said] “we found that their luminosity actually depends on the age of the stars that produce them — younger progenitors yield slightly dimmer supernovae, while older ones are brighter.” Son said the team has a high statistical confidence — 99.99% — about this age-brightness relation, allowing them to use Type 1a supernovas more accurately than before to assess the universe’s expansion… Eventually, if the expansion continues to slow down, the universe could begin to contract, ending in what astronomers imagine may be the opposite of the big bang — the big crunch. “That is certainly a possibility,” Lee said. “Even two years ago, the Big Crunch was out of the question. But we need more work to see whether it could actually happen.”

The new research proposes a radical revision of accepted knowledge, so, understandably, it is being met with skepticism. “This study rests on a flawed premise,” Adam Riess, a professor of physics and astronomy at the Johns Hopkins University and one of the recipients of the 2011 Nobel Prize in physics, said in an email. “It suggests supernovae have aged with the Universe, yet observations show the opposite — today’s supernovae occur where young stars form. The same idea was proposed years ago and refuted then, and there appears to be nothing new in this version.” Lee, however, said Riess’ claim is incorrect. “Even in the present-day Universe, Type Ia supernovae are found just as frequently in old, quiescent elliptical galaxies as in young, star-forming ones — which clearly shows that this comment is mistaken. The so-called paper that ‘refuted’ our earlier result relied on deeply flawed data with enormous uncertainties,” he said, adding that the age-brightness correlation has been independently confirmed by two separate teams in the United States and China… “Extraordinary claims require extraordinary evidence,” Dragan Huterer, a professor of physics at the University of Michigan in Ann Arbor, said in an email, noting that he does not feel the new research “rises to the threshold to overturn the currently favored model....”

The new Vera C. Rubin Observatory, which started operating this year, is set to help settle the debate with the early 2026 launch of the Legacy Survey of Space and Time, an ultrawide and ultra-high-definition time-lapse record of the universe made by scanning the entire sky every few nights over 10 years to capture a compilation of asteroids and comets, exploding stars, and distant galaxies as they change.

A new wind record has been set for Britain, with enough electricity generated from turbines to power 22 million homes, the system operator has said.

The mark of 22,711 megawatts (MW) was set at 7.30pm on 11 November… enough to keep around three-quarters of British homes powered, the National Energy System Operator (Neso) said. The country had experienced windy conditions, particularly in the north of England and Scotland…

Neso has predicted that Britain could hit another milestone in the months ahead by running the electricity grid for a period entirely with zero carbon power, renewables and nuclear… Neso said wind power is now the largest source of electricity generation for the UK, and the government wants to generate almost all of the UK’s electricity from low-carbon sources by 2030.

Gas provided only 12.5 per cent of the mix, with 11.3 per cent coming from imports over subsea power cables, 8 per cent from nuclear reactors, 8 per cent from biomass plants, 1.4 per cent from hydroelectric plants and 1.1 per cent from storage.

Britain has about 32 gigawatts of wind farms installed, approximately half of that onshore and half offshore, according to the Wind Energy Database from the wind industry body Renewable UK. That includes five of the world’s biggest offshore wind farms. The government is seeking to double onshore wind and quadruple offshore wind power by 2030 as part of its plan for clean energy....

Jane Cooper, deputy chief executive of Renewable UK, said: “On a cold, dark November evening, wind was generating enough electricity to power 80 per cent of British homes when we needed it most.

The Post analyzed a collection of thousands of publicly shared ChatGPT conversations from June 2024 to August 2025. While ChatGPT conversations are private by default, the conversations analyzed were made public by users who created shareable links to their chats that were later preserved in the Internet Archive and downloaded by The Post. It is possible that some people didn’t know their conversations would become publicly preserved online. This unique data gives us a glimpse into an otherwise black box…

Overall, about 10 percent of the chats appeared to show people talking about their emotions, role-playing, or seeking social interactions with the chatbot. Some users shared highly private and sensitive information with the chatbot, such as information about their family in the course of seeking legal advice. People also sent ChatGPT hundreds of unique email addresses and dozens of phone numbers in the conversations… Lee Rainie, director of the Imagining the Digital Future Center at Elon University, said that it appears ChatGPT “is trained to further or deepen the relationship.” In some of the conversations analyzed, the chatbot matched users’ viewpoints and created a personalized echo chamber, sometimes endorsing falsehoods and conspiracy theories.

In a post on the Zorin blog, the developers of the operating system Zorin OS 18 announced that they’ve managed to accrue one million downloads of the operating system in a single month [since its launch on October 14]. While this is plenty impressive by itself, the developers go on to reveal that, out of that million, 78% of the downloads came from a Windows machine. That means that at least 780,000 people on Windows gave Zorin OS 18 a download…

[I]t’s easy to see why: the developers put a heavy emphasis on making their system the perfect home for ex-Windows users.

Electrons can freeze into strange geometric crystals and then melt back into liquid-like motion under the right quantum conditions. Researchers identified how to tune these transitions and even discovered a bizarre “pinball” state where some electrons stay locked in place while others dart around freely. Their simulations help explain how these phases form and how they might be harnessed for advanced quantum technologies…

When electrons settle into these rigid arrangements, the material undergoes a shift in its state of matter and stops conducting electricity. Instead of acting like a metal, it behaves as an insulator. This unusual behavior provides scientists with valuable insight into how electrons interact and has opened the door to advances in quantum computing, high-performance superconductors used in energy and medical imaging, innovative lighting systems, and extremely precise atomic clocks… [Florida State University assistant professor Cyprian Lewandowski said] “Here, it turns out there are other quantum knobs we can play with to manipulate states of matter, which can lead to impressive advances in experimental research.”

Scientists in Switzerland have created a robot the size of a grain of sand that is controlled by magnets and can deliver drugs to a precise location in the human body, a breakthrough aimed at reducing the severe side effects that stop many medicines from advancing in clinical trials… “I think surgeons are going to look at this,” [said Bradley J. Nelson, an author of the paper in Science describing the discovery and a professor of robotics and intelligent systems at ETH Zurich]. I’m sure they’re going to have a lot of ideas on how to use” the microrobot. The capsule, which is steered by magnets, might also be useful in treating aneurysms, very aggressive brain cancers, and abnormal connections between arteries and veins known as arteriovenous malformations, Nelson said. The capsules have been tested successfully in pigs, which have similar vasculature to humans, and in silicone models of the blood vessels in humans and animals… Nelson said drug-ferrying microrobots of this kind may be three to five years from being tested in clinical trials. The problem faced by many drugs under development is that they spread throughout the body instead of going only to the area in need… A major cause of side effects in patients is medications traveling to parts of the body that don’t need them. The capsules developed in Switzerland, however, can be maneuvered into precise locations by a surgeon using a tool not that different from a PlayStation controller. The navigation system involves six electromagnetic coils positioned around the patient, each about 8 to 10 inches in diameter… The capsules are made of materials that have been found safe for people in other medical tools…

When the capsule reaches its destination in the body, “we can trigger the capsule to dissolve,” Nelson said.

The Sacramento County Superior Court ruled that the surveillance program run by the Sacramento Municipal Utility District (SMUD) and police violated a state privacy statute, which bars the disclosure of residents’ electrical usage data with narrow exceptions. For more than a decade, SMUD coordinated with the Sacramento Police Department and other law enforcement agencies to sift through the granular smart meter data of residents without suspicion to find evidence of cannabis growing. EFF and its co-counsel represent three petitioners in the case: the Asian American Liberation Network, Khurshid Khoja, and Alfonso Nguyen. They argued that the program created a host of privacy harms — including criminalizing innocent people, creating menacing encounters with law enforcement, and disproportionately harming the Asian community.

The court ruled that the challenged surveillance program was not part of any traditional law enforcement investigation. Investigations happen when police try to solve particular crimes and identify particular suspects. The dragnet that turned all 650,000 SMUD customers into suspects was not an investigation. "[T]he process of making regular requests for all customer information in numerous city zip codes, in the hopes of identifying evidence that could possibly be evidence of illegal activity, without any report or other evidence to suggest that such a crime may have occurred, is not an ongoing investigation,” the court ruled, finding that SMUD violated its “obligations of confidentiality” under a data privacy statute. […]

In creating and running the dragnet surveillance program, according to the court, SMUD and police “developed a relationship beyond that of utility provider and law enforcement.” Multiple times a year, the police asked SMUD to search its entire database of 650,000 customers to identify people who used a large amount of monthly electricity and to analyze granular 1-hour electrical usage data to identify residents with certain electricity “consumption patterns.” SMUD passed on more than 33,000 tips about supposedly “high” usage households to police. […] Going forward, public utilities throughout California should understand that they cannot disclose customers’ electricity data to law enforcement without any “evidence to support a suspicion” that a particular crime occurred.

The Ukrainian Army is knocking a once-hyped Russian superweapon out of the sky by jamming it with a song and tricking it into thinking it’s in Lima, Peru. The Kremlin once called its Kh-47M2 Kinzhal ballistic missiles "invincible.” Joe Biden said the missile was "almost impossible to stop.” Now Ukrainian electronic warfare experts say they can counter the Kinzhal with some music and a re-direction order. […] Kinzhals and other guided munitions navigate by communicating with Russian satellites that are part of the GLONASS system, a GPS-style navigation network. Night Watch uses a jamming system called Lima EW to generate a disruption field that prevents anything in the area from communicating with a satellite. Many traditional jamming systems work by blasting receivers on munitions and aircraft with radio noise. Lima does that, but also sends along a digital signal and spoofs navigation signals. It “hacks” the receiver it’s communicating with to throw it off course.

Night Watch shared pictures of the downed Kinzhals with 404 Media that showed a missile with a controlled reception pattern antenna (CRPA), an active antenna that’s meant to resist jamming and spoofing. “We discovered that this missile had pretty old type of technology,” Night Watch said. “They had the same type of receivers as old Soviet missiles used to have. So there is nothing special, there is nothing new in those types of missiles.” Night Watch told 404 Media that it used this Lima to take down 19 Kinzhals in the past two weeks. First, it replaces the missile’s satellite navigation signals with the Ukrainian song "Our Father Is Bandera.”

Any digital noise or random signal would work to jam the navigation system, but Night Watch wanted to use the song because they think it’s funny. “We just send a song… we just make it into binary code, you know, like 010101, and just send it to the Russian navigation system,” Night Watch said. “It’s just kind of a joke. [Bandera] is a Ukrainian nationalist and Russia tries to use this person in their propaganda to say all Ukrainians are Nazis. They always try to scare the Russian people that Ukrainians are, culturally, all the same as Bandera.” Once the song hits, Night Watch uses Lima to spoof a navigation signal to the missiles and make them think they’re in Lima, Peru. Once the missile’s confused about its location, it attempts to change direction. These missiles are fast — launched from a MiG-31 they can hit speeds of up to Mach 5.7 or more than 4,000 miles per hour — and an object moving that fast doesn’t fare well with sudden changes of direction.

“It turns out,” said [said magician Zi Teng Wang], “that pressing someone else’s phone to my hand repeatedly, trying to figure out where their phone’s RFID reader is, really doesn’t come off super mysterious and magical and amazing.” Then there are the people who don’t even have their phone’s RFID reader enabled. Using his own phone would, in Zi’s words, lack a certain “oomph.”

Oh well, how about making the chip spit out a Bitcoin address? “That literally never came up either.” In the end, Zi rewrote the chip to link to a meme, “and if you ever meet me in person you can scan my chip and see the meme.” It was all suitably amusing until the Imgur link Zi was using went down. Not everything on the World Wide Web is forever, and there is no guarantee that a given link will work indefinitely. Indeed, access to Imgur from the United Kingdom was abruptly cut off on September 30 in response to the country’s age verification rules.

Still, the link not working isn’t the end of the world. Zi could just reprogram the chip again, right? Wrong. “When I went to rewrite the chip, I was horrified to realize I forgot the password that I had locked it with.” The link eventually started working again, but if and when it stops, Zi’s party piece will be a little less entertaining. He said: “Techie friends I’ve consulted with have determined that it’s too dumb and simple to hack, the only way to crack it is to strap on an RFID reader for days to weeks, brute forcing every possible combination.” Or perhaps some surgery to remove the offending hardware.

Amid a deepening ecological crisis and acute water shortage, Tehran can no longer remain the capital of Iran, the country’s president has said. The situation in Tehran is the result of “a perfect storm of climate change and corruption,” says Michael Rubin, a political analyst at the American Enterprise Institute. “We no longer have a choice,” said Iranian president Masoud Pezeshkian during a speech on Thursday. Instead Iranian officials are considering moving the capital to the country’s southern coast. But experts say the proposal does not change the reality for the nearly 10 million people who live in Tehran and are now suffering the consequences of a decades-long decline in water supply.

The IACR said Friday that the votes were submitted and tallied using Helios, an open source voting system that uses peer-reviewed cryptography to cast and count votes in a verifiable, confidential, and privacy-preserving way. Helios encrypts each vote in a way that assures each ballot is secret. Other cryptography used by Helios allows each voter to confirm their ballot was counted fairly.
