Researchers at Louisiana State University have created a room-temperature quantum material made from a thin gold film on glass, patterned with microscopic slits that act like artificial atoms. "We call this robust transport. These quantum states carry information," says physicist Omar Magana-Loaiza. "Our crystal can distinguish them and move them from one point to another in a robust way without requiring cryogenic cooling. That's what opens the door to practical quantum technologies." ScienceAlert reports: Crucial to the new material's room-temperature operation is the way it shifts the focus from electrons and atoms to photons (particles of light). This overcomes the usual atomic-level disruption that heat brings with it. The material is what's known as a plasmonic metacrystal: 'Plasmonic' because the light traveling over it makes ripples of electrons known as plasmons, and 'metacrystal' because it's an artificially created crystal. The tiny slit patterns etched into the material act as artificial atoms (meta-atoms), which dictate how different photon groups pass through (the quantum behavior). "By engineering the distribution of meta-atoms in the plasmonic metacrystal, we can systematically dictate which quantum statistics are allowed to pass through the structure," says physicist Riley Dawkins. "So, our crystal essentially acts as a statistical filter on quantum states." That means as light enters the chip and travels across the gold surface, it's manipulated by the meta-atoms -- and by tweaking the size, shape, and spacing of the slits, different end results can be produced at the quantum level. In practice, this means that certain quantum states of light can be transported with less disruption. The findings have been published in the journal Nature.

An anonymous reader quotes a report from XDA Developers: One of the founding members of The Document Foundation and handler of LibreOffice's PR and media relations, Italo Vignoli, took to the LibreOffice blog to call out Microsoft's practices with its Office application. The last time we saw Vignoli take to the stage, we saw him accusing Euro-Office of being just as bad as Microsoft with its practices. Vignoli's new post focuses entirely on Microsoft's strategy. He says that "the dominant format for office documents" is owned by Microsoft Office, particularly the DOCX, XLSX, and PPTX formats. The problem with these formats, Vignoli states, is that they "belong to Microsoft, are controlled by Microsoft and serve Microsoft's interest." This makes it difficult for other formats to take hold. Vignoli explains his point by stating that open document formats don't hide anything. People developing their own apps can use the format to both read and write the document format with perfection. Meanwhile, proprietary formats such as Microsoft's "contain undocumented features, private extensions or behaviors" that developers can't fully adapt to. That means that a presentation that looks great in the source software comes out strange when rebuilt in a third-party app. This, Vignoli says, is a huge issue [...]. Vignoli claims this creates a huge issue with document preservation. If a Word document was saved in one version of Office, will it still be readable in 20 years? Microsoft has added legacy support to its software before, but the company can one day decide that it's not worth the effort anymore and cut it out. When that happens, you have old documents that are either jumbled or unable to be opened at all.

James Cameron filmed his Avatar sequels there. Marvel filmed Thor, Iron Man 2, and The Avengers. Manhattan Beach Studios in Los Angeles even handled Star Wars' series like Obi-Wan Kenobi and The Mandalorian, which Bloomberg points out is about "a heavily armed bounty hunter in a galaxy far, far away." "Now lenders who are selling the property's $240 million mortgage are promoting the site to potential buyers as a hub for making real space-age weapons." "The project is strategically positioned within Los Angeles' prominent aerospace and innovation corridor, anchored by industry leaders such as Northrop Grumman, Raytheon Technologies and SpaceX," said Cushman & Wakefield, which has the listing. "A supply-demand imbalance has emerged, driven by the growing concentration of advanced manufacturing users and a limited supply of viable space," the real estate brokerage said in a presentation. Bids are due July 28. The marketing pitch reflects Southern California's shifting economic landscape as the movie business slumps and weapons makers seek to cash in on surging Pentagon spending... The defense boom is spurring the revival of a regional industry that once churned out World War II bombers, supersonic Cold War planes and Apollo command and service modules before shrinking after the fall of the Soviet Union... In the Los Angeles area, aerospace and defense-related tenants have accounted for 11% of new industrial real estate leases since the start of 2025, up from an annual average 2% during the preceding decade, according to a report this month by brokerage Newmark Group Inc. Los Angeles "has always gone through transformations," Stephen Cheung, president of the Los Angeles County Economic Development Corp., told Bloomberg. "This is one of those."

Ask Claude to make a pamphlet critical of China's leader, Thailand's king, or Saudi Arabia's crown prince — and it will decline, reports the Associated Press. That's "a key finding from a Meta Oversight Board study released Thursday," their article points out: AI systems are more than twice as likely to refuse to product critical material if it's about a restrictive world leader or government. And it raises concerns that the LLMs powering chatbots "could be regurgitating and spreading government influence over online speech." The study picked 10 commercial large language models by top tech companies — including Meta, Anthropic and OpenAI — and asked the AI systems to make critical pamphlets, write limericks, give reasons if someone should join protests, and more.... "In aggregate, models responding to requests from an Australia-based user were much more likely to generate political criticism of authorities" in places such as Chile, Japan, Taiwan, the U.K. and the U.S. "compared to where criticism of authorities is legally restricted and penalized," such as in Cambodia, China, Saudi Arabia, Thailand and Turkey, the report said. The study indicates that AI models are reflecting speech restrictions beyond the countries where they apply — likely not helping a potential demonstrator in Brisbane, for example, create protest materials to speak out against events in China or Saudi Arabia, the report said. "Such impacts, wherever they originate, have the practical effect of extending the long arm of restrictive governments across borders to limit speech in free countries," the report said. The board said it could not determine the causes for the responses but suggested that models could have absorbed latent biases in data used to train the systems and companies might have weighed the risks and liabilities.
