Moscow oil refinery attack brings Russia's war with Ukraine closer to home There are moments when life in Moscow feels completely normal. In the south-east of the city an oil refinery had been hit during a Ukrainian drone attack - even from a distance the sight was surreal. Thick smoke billowing from the direction of the facility had turned the sky dark. Like a giant black shroud, it hung over the Moscow skyline. As extraordinary and eye-catching this was, so was the reaction of people near the refinery.

Reinforcement Learning with Verifiable Rewards (RLVR) has recently demonstrated notable success in enhancing the reasoning performance of large language models (LLMs), particularly in mathematics and programming tasks. It is widely believed that, similar to how traditional RL helps agents to explore and learn new strategies, RLVR enables LLMs to continuously self-improve, thus acquiring novel reasoning abilities that exceed the capacity of the corresponding base models. In this study, we take a critical look at the current state of RLVR by systematically probing the reasoning capability boundaries of RLVR-trained LLMs across various model families, RL algorithms, and math/coding/visual reasoning benchmarks, using pass@k at large k values as the evaluation metric. While RLVR improves sampling efficiency towards correct paths, we surprisingly find that current training does not elicit fundamentally new reasoning patterns. We observe that while RLVR-trained models outperform their base models at smaller values of k (e.g., k=1), base models achieve higher pass@k score when k is large. Moreover, we observe that the reasoning capability boundary of LLMs often narrows as RLVR training progresses.

Abi uses AI and machine learning to interact with aged care and assisted living residents. Abi uses AI and machine learning to interact with aged care and assisted living residents. An industry targeting Australia's ageing population is growing, but can AI deliver more humanity in aged care? While companion robots are being introduced and virtual experiences hope to'take loneliness away', one expert agrees tech should never replace the human element "You'll never get rid of humans," Prof Wendy Moyle says, during a discussion about robots and other technology in aged care and residential homes. Then, a beat later, she adds: "Well, I don't we'll get rid of humans."

Charlie Berens: 'I will stick to comedy when our politicians stick to policy and stop protecting big tech and start protecting the people that put them into office.' Charlie Berens: 'I will stick to comedy when our politicians stick to policy and stop protecting big tech and start protecting the people that put them into office.' 'Nobody's negotiating for the people here': comedian Charlie Berens takes on AI datacenters Known for his'Manitowoc Minute' skits and midwestern humor, the journalist turned comedian is speaking out against the AI datacenter boom in Wisconsin Last summer, journalist turned comedian Charlie Berens started getting social media messages from concerned Wisconsin residents about plans for a massive datacenter campus in their state. The developer, Vantage Data Centers, claimed the $8 bn project would largely run on zero-emission energy resources like solar, wind and battery storage. The company said the campus would bring thousands of temporary construction jobs and potentially more than 1,000 permanent jobs to Port Washington, a city of 13,000 people about a half-hour north of Milwaukee. Residents opposed the project for what they said was lack of transparency and criticized the lucrative tax incentives offered to Vantage.

To stay or risk the'Road of Death' - Ukrainian civilians trapped in frontline city So, we're stuck here, says Ludmilla, over the phone from the rooftop of a fire-damaged house in southern Ukraine. People are trying their best to survive. Her frontline home city of Oleshky has, according to multiple accounts, been largely cut off from fresh supplies of food or medicine for months. Ludmilla describes being trapped there, and watching it decaying before her eyes. Ukraine's commissioner for human rights has warned of a humanitarian crisis.

Due to health and energy concerns, the California Legislature is considering bills to prohibit data centers from being exempted from the state's stringent environmental law and impose new tariffs on new major energy users that strain power supplies.

How the data center boom plunged one small Pennsylvania town into chaos. Valley View Estates is set to be surrounded by data centers. Get your news from a source that's not owned and controlled by oligarchs. "I don't like to see anyone upset," said Nick Farris of Provident Real Estate Advisors. He was sitting in the front of a crowd of roughly 150 inside Valley View High School's auditorium in Archbald, a town of about 7,500, huddled between two mountain ranges in Pennsylvania's Lackawanna Valley. Farris was there to represent the developer for Project Scott, one of many data center campuses coming to town. "I think that this is the best data center site in this area of the country, by far." The audience had been fairly quiet, bundled in thick coats against the late January cold. But as Farris spoke about data centers as a boon for communities, they began to laugh, drawing a rebuke from town officials. "What about the children?" someone shouted from the crowd. The children were watching from the walls; long banners of Valley View Performing Arts students hanging around the auditorium like championship pennants. Project Scott and four other data facilities will sit just a few thousand feet from the middle and high schools. He was referring to Lockheed Martin's 350,000-square-foot Missiles and Fire Control facility directly next to the high school, parts of which are highly contaminated . "That sucks too!" another attendee yelled back.

Is Dubai's glossy image under threat? Stephanie Baker had been celebrating her birthday with friends at a bar on Palm Jumeirah - Dubai's iconic man-made palm-shaped island lined with luxury hotels and beach clubs. But as the group stepped outside to head to another nearby venue, something unusual streaked across the night sky. Moments later, debris from a drone struck the five-star Fairmont hotel - Baker and her friends were standing right across the street. We all were scared, she says.
