"As employers and tech companies rush to deploy AI software into workplaces to improve efficiency, labor unions are stepping up work with state lawmakers across the nation to place guardrails on its use..." reports the Washington Post. "Union leaders say they must intervene to protect workers from the potential for AI to cause massive job displacement or infringe on employment rights." In Massachusetts, the Teamsters labor union is backing a proposed state law that would require autonomous vehicles to have a human safety operator who can intervene during the ride, effectively forbidding truly driverless rides. Oregon lawmakers recently passed a bill supported by the Oregon Nurses Association that prohibits AI from using the title "nurse" or any associated abbreviations. The American Federation of Labor and Congress of Industrial Organizations, a federation of 63 national and international labor unions, launched a national task force last month to work with state lawmakers on more laws that regulate automation and AI affecting workers... The AFL-CIO task force plans to help unions take on problematic use of AI in collective bargaining and contracts and in coming months to develop a slate of model legislation available to state leaders, modeled on recently passed and newly proposed legislation in places including California and Massachusetts. The president of the California Federation of Labor Unions also supports a proposed state law "that would prevent employers from primarily relying on AI software to automate decisions like terminations or disciplinary actions," according to the article. "Instead, humans would have to review decisions. The law would also prohibit use of tools that predict workers' behaviors, emotional states and personality."

Sunlight becomes energy when plants convert four photons of light. But unfortunately, most attempts at synthetic light-absorbing chemicals can only absorb one photon at a time, write two researchers from the University of Melbourne. "In the Polyzos research group at the School of Chemistry, we have developed a new class of photocatalysts that, like plants, can absorb energy from multiple photons." This breakthrough allows us to harness light energy more effectively, driving challenging and energy-demanding chemical reactions. We have applied this technology to generate carbanions — negatively charged carbon atoms that serve as crucial building blocks in the creation, or synthesis, of carbon- and hydrogen-rich chemicals known as organic chemicals. Carbanions are vital in making drugs, polymers and many other important materials. However, traditional methods to produce carbanions often require lots of energy and dangerous reagents, and generate significant chemical waste, posing environmental and safety challenges... Our new method offers a greener, safer alternative [using visible light and renewable starting materials]... We've used it to synthesize important drug molecules, including antihistamines, in a single step using simple, cheap and commonly available "commodity chemicals" — amines and alkenes. And importantly, the reaction scales well in commercial-scale continuous flow reactors, highlighting its potential for industrial applications. "By learning from the subtle mastery of photosynthesis," the researchers write, their group "is forging a new paradigm for chemical manufacturing — one where sunlight powers sustainable and elegant solutions for the molecules that shape our world."

An anonymous reader shared this report from Tom's Hardware: According to German news outlet Heise, notable progress has been made regarding the counterfeit Seagate hard drive case. Just like something out of an action movie, security teams from Seagate's Singapore and Malaysian offices, in conjunction with local Malaysian authorities, conducted a raid on a warehouse in May that was engaged in cooking up counterfeit Seagate hard drives, situated outside Kuala Lumpur. During the raid, authorities reportedly uncovered approximately 700 counterfeit Seagate hard drives, with SMART values that had been reset to facilitate their sale as new... However, Seagate-branded drives were not the only items involved, as authorities also discovered drives from Kioxia and Western Digital. Seagate suspects that the used hard drives originated from China during the Chia [cryptocurrency] boom. Following the cryptocurrency's downfall, numerous miners sold these used drives to workshops where many were illicitly repurposed to appear new. This bust may represent only the tip of the iceberg, as Heise estimates that at least one million of these Chia drives are circulating, although the exact number that have been recycled remains uncertain. The clandestine workshop, likely one of many establishments in operation, reportedly employed six workers. Their responsibilities included resetting the hard drives' SMART values, cleaning, relabeling, and repackaging them for distribution and sale via local e-commerce platforms.

"Illinois last week banned the use of artificial intelligence in mental health therapy," reports the Washington Post, "joining a small group of states regulating the emerging use of AI-powered chatbots for emotional support and advice." Licensed therapists in Illinois are now forbidden from using AI to make treatment decisions or communicate with clients, though they can still use AI for administrative tasks. Companies are also not allowed to offer AI-powered therapy services — or advertise chatbots as therapy tools — without the involvement of a licensed professional. Nevada passed a similar set of restrictions on AI companies offering therapy services in June, while Utah also tightened regulations for AI use in mental health in May but stopped short of banning the use of AI. The bans come as experts have raised alarms about the potential dangers of therapy with AI chatbots that haven't been reviewed by regulators for safety and effectiveness. Already, cases have emerged of chatbots engaging in harmful conversations with vulnerable people — and of users revealing personal information to chatbots without realizing their conversations were not private. Some AI and psychiatry experts said they welcomed legislation to limit the use of an unpredictable technology in a delicate, human-centric field.

"The planet Uranus emits more heat than it gets from the Sun," reports Science Daily , citing a new study led by University of Houston researchers, in collaboration with planetary scientists worldwide. "This means it's still slowly losing leftover heat from its early history," says the first author on the paper, "a key piece of the puzzle that helps us understand its origins and how it has changed over time." The study found the planet emitting about 12.5% more heat than it absorbs via sunlight, which "suggests Uranus does have its own internal heat — an advance that not only informs NASA's future missions but also deepens scientists' understanding of planetary systems, including processes that influence Earth's climate and atmospheric evolution." The discovery resolves a long-standing scientific mystery about the giant planet, because observational analyses from Voyager 2 in 1986 didn't suggest the presence of significant internal heat — contradicting scientists' understanding of how giant planets form and evolve... Additionally, the team's methodology provides testable theories and models that could also be applied to explore radiant energy of other planets within and beyond our solar system... It could even impact technology innovation and climate understanding on Earth [giving insights intoi "the fundamental processes that shape planetary atmospheres, weather systems and climate systems," said one of the paper's authors.] The article adds that the researchers now think the planet "may have a different interior structure or evolutionary history compared to the other giant planets."
