Science magazine reports: For decades, string theory promised a "theory of everything" that described all particles and forces as tiny vibrating strings. Physicists hoped it could also solve one of the field's deepest problems: reconciling quantum mechanics with gravity. But as string theory grew increasingly elaborate — and experimentally unreachable — many physicists lost hope. Now, some researchers are revisiting the theory from first principles. In a paper in press at Physical Review Letters, Clifford Cheung, a physicist at the California Institute of Technology, and colleagues lay out a small set of assumptions about the universe and show that they inevitably give rise to string theory.... Cheung's study, along with another one posted to arXiv in January, starts with two reasonably conservative assumptions: that the probabilities of all possible outcomes of an event add up to 100%, and that the laws of physics are consistent for observers moving at different speeds. Each group then posits additional assumptions that have not been borne out by observations. Cheung's analysis invokes "ultrasoftness," the idea that the probability of certain particle interactions drops off at a particular rate at high energies. The second study, led by University of Michigan physicist Henriette Elvang, instead assumes "supersymmetry," a maximal coupling between matter and forces. Both groups conclude the only theory that can satisfy their assumptions is one that looks like string theory... Cheung and Elvang stress that their aim is not to prove the inevitability of string theory. "I don't have a dog in the fight; I just work here," Cheung says. Rather, the goal is to explore the space of possible theories under rigid constraints — regardless of whether they reflect reality... The one thing the researchers all agree on is that the field would benefit from more alternative models to string theory. Cheung sees the agnostic, bottom-up exploration as a step in that direction. "You can either give up on the problem because it's too culturally toxic, or you can ask: If you want to find an alternative, what do you need?" he says. "Now, we know exactly what to do."

A "growing wave" of Reddit's "promoted posts" are sending U.S. and European audiences to money-stealing scams that impersonate major news organizations including the BBC, the Financial Times, and The Guardian, according to new findings from Bitdefender Labs. "Domains are short-lived and rapidly rotated to evade detection," they write, noting that the impersonating sites apparently even use language "to falsely imply that the investment platform had been reviewed, approved, or vetted" by the legitimate site they're impersonating: The campaign promotes fake AI-powered investment platforms such as Wencoin STX, Warrior Coin AI, and Nevo Coin, using fabricated celebrity endorsements, cloned news websites, fake interviews, and invented financial success stories to lure victims into depositing money. Researchers Andrea Olariu and Emanuel Puscasu have identified multiple promoted Reddit posts masquerading as legitimate financial or breaking news stories. Some ads claimed that: — NVIDIA and OpenAI were "creating the future" — Heathrow police discovered hundreds of thousands of pounds in cash — Governments and banks were allegedly trying to "hide" a revolutionary AI investment platform — European regulators were "silencing" articles about AI trading systems Some Reddit ads delivered in video format, including what appeared to be a deepfake BBC news segment featuring a news anchor presenting fabricated financial headlines... Examples observed by researchers included: — Fake BBC pages discussing "$20 billion conversations" tied to AI investments — Fraudulent Financial Times articles about Heathrow airport cash seizures — Fake Guardian stories claiming governments were trying to suppress coverage of Wencoin STX or Nevo Coin The pages featured fabricated interviews, fake profit screenshots, manipulated banking documents, false testimonials, and even fictional journalists or business editors designed to make the scam look legitimate. In many cases, the content sought to create a sense of exclusivity or conspiracy, suggesting that banks, regulators, or governments were trying to suppress public access to the investment platform... Our researchers found that after users clicked links embedded within the fake Guardian articles, they were redirected to a registration form allegedly used to create a "Nevo Coin" investment account. The form requested personal contact information, including the victim's name, email address, and phone number. To increase pressure and encourage immediate action, the page warned that registration availability was limited, claiming that once all spots were filled, new user registrations would be suspended. And in the final stage, they're asked to deposit money...

U.S. Senator Bernie Sanders announced a plan for the public to take a 50% ownership stake in AI companies, remembers the Associated Press. And then OpenAI's Sam Altman "told Sanders that he, too, wants the public to have equity in AI companies." Though the CEO said he couldn't support Sanders' threshold of 50%, he nonetheless wanted to work with him to advocate for the general idea, according to people with knowledge of the conversation. The nearly hourlong meeting in Sanders' Senate office this week, held at Altman's request, highlighted the inherent tension between AI powerhouses and policymakers as Americans are increasingly asked to accept the costs of the AI boom even as they remain unconvinced of its direct benefits. Yet it's also creating odd political bedfellows fueled by populism as politicians from Sanders to President Donald Trump embrace giving the public a stake in AI's growth. Speaking to reporters on Air Force One on Friday, Trump described a potential partnership "where the American people can benefit from the success of AI" and said executives from leading AI companies will visit the White House, "probably next week," to discuss the idea. The article points out that Altman also met with congressional leaders from both of America's political parties.

Ars Technica shares some anecdotes from Steve Jobs in Exile, a new book released last month: [Author Geoffrey] Cain reminds us, in stunning detail, that Jobs' "exile" era at NeXT was not only critical to his evolution as a man and an entrepreneur, but that it mattered for the rest of us, too. The technological innovations that came out of NeXT — notably, the NeXTSTEP OS — continue to live on in what we now call both macOS and iOS. As Cain puts it, "NeXTSTEP was Steve's attempt to make Unix taste sweet...." [W]hile many tech nerds know that Tim Berners-Lee created the first World Wide Web server on a NeXT machine while working in Switzerland in 1990, few know that NeXT employees were wary of bringing the news to Jobs. Why? They feared his wrath "and that he would dismiss [the web] as 'shit.'" (In another timeline, NeXT might itself have capitalized on this world-changing innovation....) Perhaps one of the wildest anecdotes that Cain uncovered was how one voicemail changed computer history forever. In 1996, when Apple was solidly in its mediocre Performa era — and considering buying BeOS as the basis for its new operating system — a mid-level NeXT product manager asked aloud, "Why don't we just frickin' call Apple?" (NeXT was also struggling during this period.) And so someone did. As Cain writes: Garrett left the group of managers, walked back to his office, and took a risk. He picked up his designer phone and called the head of software at Apple. He left what he described as "one of my more inspired sales pitches" on the man's voicemail, explaining why Apple should be looking at NeXT instead of Be... In any other universe, Garrett's call might have gotten him fired. But in this timeline, it worked out. And thanks to him, Steve [Jobs] was about to enter Apple's airspace once again.

"A DNA-editing feat involving editing the genes of early stage embryos was announced this week," reports the Wall Street Journal. They describe the feat as "a far cry from designer babies, but nevertheless a step in that direction." Dieter Egli, an associate professor of developmental cell biology at Columbia University and his co-authors, including Nathan Treff of Nucleus Genomics, a New York-based DNA-testing startup, say the technology could help fix disease-causing mutations in embryos. "We're not throwing the final 'OK, you will have gene-edited babies tomorrow' at the public," said Egli. "That is a process that can occur through discussion matched with scientific progress...." Previous gene-editing efforts have often used Crispr, which can cut out parts of the DNA sequence, but the technology can also cause damage if the wrong DNA is targeted or cut out. In 2018, Chinese scientist He Jianku said he used Crispr to tweak DNA in human embryos and was imprisoned for the work. The technology Egli's group used, called base editing, allows them to target individual DNA letters in sequences more precisely with fewer adverse effects... Egli's group focused on altering two genes, one that can raise the risk of heart disease and one that is tied to blood disorders like sickle cell disease, and the research showed they were sometimes able to do so successfully, in the same embryo, without damage. "I am generally supportive of the concept of embryo editing to prevent genetic disease," said Dr. Paula Amato, a fertility expert at Oregon Health & Science University who wasn't involved in the research... Base editing has been used in human embryos before, according to peer-reviewed studies. The technology was used to correct a disease-causing mutation and an Alzheimer's disease-risk gene variant, said Alexis Komor, associate professor of biochemistry and molecular biophysics at the University of California, San Diego, who wasn't involved in the work. "There really is not any unmet medical or clinical need for this, especially from an in vitro fertilization perspective," Komor said. "Usually what you'll hear is that they're doing it just so that you know we can prevent genetic diseases, but there are so many other better ways to do that." Using embryo editing to create babies is illegal in the U.S. and many other countries. Scientists have long worried that it is a slippery slope and that the technology could ultimately be used to promote eugenics. Her worry is that "they're basically building a blueprint" for more ethically problematic forms of embryo editing. "In my opinion, I think this is a huge no-no," Komor said. "There's just no ethical way to use this...." Nucleus Genomics Chief Executive Kian Sadeghi said his company plans to fund Egli's further research, building on the new findings. His company sells a polygenic embryo-screening product, which screens prospective parents' embryos and produces risk scores for their likelihood of developing disease, as well as factors like height, IQ and eye color. The company has said the IQ predictions are limited in accuracy. The research was published online Monday on a preprint server.
