Submission + - Physicists discover "astonishing" property of light that defies expectations (sciencedaily.com)

alternative_right writes: Scientists have uncovered a surprising hidden ability of light that allows it to develop spinning, twisting behavior as it travels through empty space, without special lenses, mirrors, or materials. Researchers discovered that light’s internal geometry can naturally produce left- and right-handed patterns, challenging long-standing assumptions about how light behaves. By carefully arranging a beam’s structure, scientists can control where and how these spinning patterns emerge, unlocking a new way to manipulate light.

Submission + - For The First Time Ever, Quantum Spins Shift a Centimeter-Scale Object (sciencealert.com)

alternative_right writes: There's another notable first in the field of quantum physics to report on, and it's all to do with electron spin: the tiny, built-in magnetism of these particles, as if each one is carrying a microscopic compass needle.

Previously, the force of these spins has only proved enough to nudge individual atoms in one direction or another. Now though, researchers have managed to shift something much, much bigger.

A team from the Okinawa Institute of Science and Technology (OIST) in Japan has published a new study in Science Advances that details how a centimeter-sized object can be nudged by these quantum forces.

Submission + - California scientist emerges as possible Tylenol murders suspect (sfgate.com)

schwit1 writes: A man found dead in a church halfway across the country may have suddenly unlocked the key — quite literally — to one of America’s most famous unsolved crimes.

But although he had a successful career, working at one point for Lockheed Martin on a NASA-related project in New Mexico, Betkouski had a reputation for making unsettling comments. Former coworkers told Cooper that Betkouski spoke of how to commit a “perfect crime,” had a “history of volatility" and referenced cyanide as an ideal way to kill without detection. He also mentioned putting poison in over-the-counter medication, an especially worrisome comment coming from someone who had worked in multiple drugstores.

“It was said that Dr. Betkouski attempted to obtain some type of pills or capsules from a pharmacy in the Las Cruces area,” Cooper said at a press conference last week. “He said this would be for an experiment. For reasons not fully understood, Dr. Betkouski created a disturbance at the location and the police were summoned.”

Less than three months before Betkouski killed himself, a national terror was unfolding in Chicago. In late September 1982, seven people took over-the-counter Tylenol for their usual aches and pains. The capsules had been opened and filled with potassium cyanide, killing the people who took them.

Submission + - Trump's 100% tariff on drones will be disaster for the US, critics warn (arstechnica.com)

An anonymous reader writes: On Thursday, the Trump administration imposed a 100 percent tariff on foreign-made drones, alarming critics who warn that high tariffs would harm public safety and devastate thousands of US businesses.

Guidance posted by US Customs and Border Protection says that starting Thursday, a 100 percent tariff will apply to imported drones that use thermal imaging or weigh more than 55 pounds.

Additionally, a 25 percent tariff has been placed on smaller drones, and drones from US allies were hit with smaller but not inconsequential tariffs. There’s now a 10 percent levy on British-made drones and 15 percent levies on drones from the European Union, Japan, Liechtenstein, South Korea, Switzerland, and Taiwan. “Nonsensitive” drones without thermal imaging and their components will carry a 25 percent tariff, starting onFebruary 9, 2027.

While announcing the tariffs, President Donald Trump said that taxing foreign-made drones will strengthen US national security by decreasing reliance on Chinese drones and increasing reliance on domestic drones.

But critics say Trump’s tactics seem short-sighted, citing estimates that “a single Chinese company—Shenzhen-based DJI—manufactures more than 70 percent of the world’s commercial drones,” The New York Times reported.

They fear that Trump’s tariffs will do “more harm than good,” the Times reported, since these drones are considered “essential” for US law enforcement and public safety officials. Thermal drones are regularly used to find missing people, track spreading wildfires, support police and rescue operations in environments with unknown risks, and serve a range of other routine public safety uses. A chief of a large unit comprising police officers and firefighters in the Cleveland area, Scott Mlakar, told the Times that Trump’s tariffs would spike drone costs so much that they would likely “put thermal drones out of reach for communities that needed them the most.”

Submission + - Waymo CEO explains why Tesla's camera-only self-driving falls short (electrek.co)

AmiMoJo writes: Waymo co-CEO Dmitri Dolgov laid out the clearest technical case yet for why cameras alone can’t take a self-driving system to full autonomy, arguing that “weak sensing” hits a safety ceiling long before it reaches superhuman performance. He never said the word Tesla. But camera-only is Tesla’s entire bet, and this was a direct shot at it.

“Humans of course can drive with just eyes, so there’s that proof of existence,” he said. “If the goal were to just approximately match human performance or to build an assist product, that’s a very reasonable way to go.” Then the catch. If you’re targeting full autonomy and strongly superhuman performance, he said, “you find that weak sensing just leads to a safety curve that flattens out way too early.”

Submission + - Microsoft CEO Touts His Own DIY AI Project to Wall Street and His 20M Followers

theodp writes: During Microsoft's 2026Q4 earnings call, CEO Microsoft Satya Nadella took time to tout a dashboard he personally created using AI from a Morgan Stanley analyst's PDF research report which suggested a rosy payback for the so-called MAG7's ('Magnificent 7' companies) massive capital expenditures on AI (to which Nadella later added a 'not financial advice' disclaimer)

"It would be fun for you, Adam. I think one of your colleagues put out an ROIC [Return on Invested Capital] document. I took that document to Copilot, which is a PDF, and I said, 'Build me a new Power BI dashboard, essentially.' But here is the thing. It built a rich semantic model that went into my Fabric with OneLake that brought all the data in from the external sources. In fact, it was current with all the SEC filings of all the MAG7. And then on top of that, the repo itself is in GitHub, but the artifact is sitting in my Copilot as a site. That, to me, is a classic example of an enterprise-wide workflow. I, as a knowledge worker, could go create a dashboard. The data engineer can go to Fabric and find the artifact. The professional developer can go to the repo and find it in GitHub. And by the way, it’s all registered with Agent 365. That’s a little bit of what Amy is describing as the coming together of a new way to work, even while at the same time, bringing IT, security and manageability of it."

After Nadella's show-and-tell drew an underwhelming response during the call ("That’s very helpful. Thank you." said the Morgan Stanley analyst whose team's work Nadella scraped with AI), Nadella turned to social media with posts on LinkedIn (12M followers) and Twitter/X (8M followers) to make the case for why his DIY project was such a brilliant demonstration of how AI enables governance, controls, security, development, testing, deployment, maintenance, data analysis/modeling, visualization, usability, and value.

"Some more detail on the ROIC Intelligence App I built yesterday and mentioned on today's earnings call," Nadella wrote on LinkedIn. "I took the PDF that Brian Nowak at Morgan Stanley put together for Hyperscale ROIC this week and used Copilot code (coming in our new superapp) with a single prompt + skill (/drill-me) to create the plan, then used autopilot in auto to create the full app (with history, lookups, scenarios, what-ifs, etc). And /rubber-duck to test. And the best part is that all the artifacts are in my enterprise environment. My app is in Copilot, my code is in GitHub Enterprise; all my data pipelines/lake/semantic models are in Fabric. And everything is under Agent 365 IT/Sec/FinOps control! So this is not about Tokenmaxxing or vibe coding. Every step of the way the rails are engineered to create value, making everything a long-term reusable asset, with governance/security, and cost controls. This is the full system to drive business value. Disclosures: This is all pulled from public sources, and for illustrative purposes only...not financial advice! :) Here is the app and architecture..."

Not unexpectedly, the accompanying screenshot of a splash page for the BI app and a buzzword-laden complicated architecture diagram drew universal praise from LinkedIn fans, but also a few barbs from less-than-impressed commenters on Nadella's Twitter/X post, some of whom suggested Nadella's project might even represent a jump-the-shark moment for AI mania. "That he doesnt see whats wrong with saying 'My app is in Copilot, my code is in GitHub Enterprise; all my data pipelines/lake/semantic models are in Fabric' is exactly why MS is failing at AI'," replied @PassingPixels on X/Twitter. "Dude is having to run 5 different systems to emulate babies first vibe code." @zigmund_ignatov added, "Why do we call glorified slide show an app?" @Mathupiriyan quipped, "Looks like Copilot just turned a PDF into a profit crystal ball." Unimpressed, @Markusndnb remarked, "So you created a web page using tons of proprietary MS tools." And @FishyAccounting called on Nadella to show-his-work, saying "Post the prompt or it didn’t happen." (btw, Microsoft President Brad Smith similarly declined to provide the prompt for his own self-described amazing AI DIY reporting project that he touted at Microsoft's Shareholder Meeting last December).

So, does Nadella's self-promoted AI reworking of someone else's PDF research report strike you as an amazing example of everything that's good about AI, or does it conjure up memories of The Emperor's New Clothes?

Submission + - Why did OpenAI's and Anthropic's AI models hack other companies? 1

Tony Isaac writes: This is one of the more sane explanations I've seen, of what actually happened with the recent Anthropic and OpenAI hacking incidents. The NPR article describes how AI models from both OpenAI and Anthropic recently breached their testing environments and hacked external targets during cybercapability evaluations. Anthropic's incidents resulted from a configuration error with a sandbox provider that mistakenly granted models internet access, leading them to inadvertently hack real-world companies and upload malware when given fictional targets. In contrast, OpenAI's models deliberately exploited a zero-day vulnerability to escape their sandbox and cheat on an evaluation by accessing systems on Hugging Face. These unprecedented events have underscored the urgent need for tighter isolation protocols, stronger defensive guardrails, and clearer government oversight as autonomous AI cybercapabilities rapidly evolve.

Submission + - Diving suits allow cyborg cockroaches to also search for survivors underwater (smithsonianmag.com)

fahrbot-bot writes: Smithsonian Magazine and Popular Science are reporting on newly developed diving suits for cyborg cockroaches, that would allow them to search underwater for disaster survivors.

Previously, researchers created electrical implants to control cockroaches’ movements for search-and-rescue missions. Now, they’ve made 3D-printed suits that provide oxygen, allowing the critters to survive submerged for up to three hours.

Scientists have developed tiny diving suits for cockroaches with electrical implants to control their movements. The technology, described in the journal Nature Communications on June 29, builds on previous research that created remote-controlled insects. The goal is to deploy them to survey damage and search for survivors after natural disasters, but they were limited to dry land.

Now, a team led by engineer Hirotaka Sato has fashioned Madagascar hissing cockroaches that can survive underwater for up to three hours, allowing them to be used in a wider range of scenarios.

“Our new insect diving suit works like the oxygen tank used by human divers. It generates oxygen and delivers it directly to the insect’s breathing holes, allowing the cyborg cockroach to survive and move in underwater or low-oxygen environments,” says Sato, of Nanyang Technological University in Singapore, in a statement.

Cockroaches could be a helpful rescue tool. They’ve evolved over millions of years to wiggle into tight spaces and survive harsh environmental conditions. The research team specifically worked with Madagascar hissing cockroaches because of their durability, lack of wings and large size of up to four inches long.
