macOS 26 Tahoe: The Ars Technica review

macOS 26 Tahoe: The Ars Technica review

fivenewscrypto    septembre 16, 2025   

The last time Apple gave macOS a fresh design was in 2020's macOS 11 Big Sur.

That release was relatively light on new features and heavy on symbolism. Big Sur is also when Apple finally jettisoned the "10" in Mac OS X after two decades. More importantly, it was the first release installed on then-new Apple Silicon Macs, the culmination of a decade-plus of in-house chip design that began with single-core, low-power iPhone and iPad chips and culminated in something powerful enough for the Mac Pro.

Today's macOS 26 Tahoe release holds up a translucent, glassy mirror to the Big Sur update. It comes with an all-new look, one that further unifies Apple's design language across all its operating systems. And it even throws out the old version numbering system and introduces a new one.

Get into the cockpit as new crop of “Top Gun” pilots get their wings

Get into the cockpit as new crop of “Top Gun” pilots get their wings

fivenewscrypto    septembre 16, 2025   

The blockbuster success of the 1986 film Top Gun—chronicling the paths of young naval aviators as they go through the grueling US Navy's Fighter Weapons School (aka the titular Top Gun)—spawned more than just a successful multimedia franchise. It has also been credited with inspiring future generations of fighter pilots. National Geographic takes viewers behind the scenes to see the process play out for real, with its new documentary series, Top Guns: The Next Generation.

Each episode focuses on a specific aspect of the training, following a handful of students from the Navy and Marines through the highs and lows of their training. That includes practicing dive bombs at break-neck speeds; successfully landing on an aircraft carrier by "catching the wire"; learning the most effective offensive and defensive maneuvers in dogfighting; and, finally, engaging in a freestyle dogfight against a seasoned instructor to complete the program and (hopefully) earn their golden wings. NatGeo was granted unprecedented access, even using in-cockpit cameras to capture the pulse-pounding action of being in the air, as well as capturing behind-the-scenes candid moments.

How does reality stack up against its famous Hollywood depiction? "I think there is a lot of similarity," Capt. Juston "Poker" Kuch, who oversees all training and operations at NAS Meridian, told Ars. "The execution portion of the mission gets focused in the movie so it is all about the flight and the dogfighting and dropping the bombs. What they don't see is the countless hours of preparation that go into the mission, all the years and years of training that it took to get there. You see the battle scenes in Top Gun and you're inspired, but there's a lot of time and effort that goes in to get an individual to that point. It doesn't make for good movies, I guess."

China rules that Nvidia violated its antitrust laws

China rules that Nvidia violated its antitrust laws

fivenewscrypto    septembre 16, 2025   

A Chinese regulator has found Nvidia violated the country’s antitrust law, in a preliminary finding against the world’s most valuable chipmaker.

Nvidia had failed to fully comply with provisions outlined when it acquired Mellanox Technologies, an Israeli-US supplier of networking products, China’s State Administration for Market Regulation (SAMR) said on Monday. Beijing conditionally approved the US chipmaker’s acquisition of Mellanox in 2020.

Monday’s statement came as US and Chinese officials prepared for more talks in Madrid over trade, with a tariff truce between the world’s two largest economies set to expire in November.

The US is trying to kick-start a “nuclear energy renaissance”

The US is trying to kick-start a “nuclear energy renaissance”

fivenewscrypto    septembre 16, 2025   

In May, President Donald Trump signed four executive orders to facilitate the construction of nuclear reactors and the development of nuclear energy technology; the orders aim to cut red tape, ease approval processes, and reshape the role of the main regulatory agency, the Nuclear Regulatory Commission, or NRC. These moves, the administration said, were part of an effort to achieve American independence from foreign power providers by way of a “nuclear energy renaissance.”

Self-reliance isn’t the only factor motivating nuclear power proponents outside of the administration: Following a decades-long trend away from nuclear energy, in part due to safety concerns and high costs, the technology has emerged as a potential option to try to mitigate climate change. Through nuclear fission, in which atoms are split to release energy, reactors don’t emit any greenhouse gases.

The Trump administration wants to quadruple the nuclear sector’s domestic energy production, with the goal of producing 400 gigawatts by 2050. To help achieve that goal, scientific institutions like the Idaho National Laboratory, a leading research institute in nuclear energy, are pushing forward innovations such as more efficient types of fuel. Companies are also investing millions of dollars to develop their own nuclear reactor designs, a move from industry that was previously unheard of in the nuclear sector. For example, Westinghouse, a Pennsylvania-based nuclear power company, plans to build 10 new large reactors to help achieve the 2050 goal.

60 years after Gemini, newly processed images reveal incredible details

60 years after Gemini, newly processed images reveal incredible details

fivenewscrypto    septembre 16, 2025   

Six decades have now passed since some of the most iconic Project Gemini spaceflights. The 60th anniversary of Gemini 4, when Ed White conducted the first US spacewalk, came in June. The next mission, Gemini 5, ended just two weeks ago, in 1965. These missions are now forgotten by most Americans, as most of the people alive during that time are now deceased.

However, during these early years of spaceflight, NASA engineers and astronauts cut their teeth on a variety of spaceflight firsts, flying a series of harrowing missions during which it seems a miracle that no one died.

Because the Gemini missions, as well as NASA's first human spaceflight program Mercury, yielded such amazing stories, I was thrilled to realize that a new book has recently been published—Gemini & Mercury Remastered—that brings them back to life in vivid color.

Scientists: It’s do or die time for America’s primacy exploring the Solar System

Scientists: It’s do or die time for America’s primacy exploring the Solar System

fivenewscrypto    septembre 16, 2025   

Federal funding is about to run out for 19 active space missions studying Earth's climate, exploring the Solar System, and probing mysteries of the Universe.

This year's budget expires at the end of this month, and Congress must act before October 1 to avert a government shutdown. If Congress passes a budget before then, it will most likely be in the form of a continuing resolution, an extension of this year's funding levels into the first few weeks or months of fiscal year 2026.

The White House's budget request for fiscal year 2026 calls for a 25 percent cut to NASA's overall budget, and a nearly 50 percent reduction in funding for the agency's Science Mission Directorate. These cuts would cut off money for at least 41 missions, including 19 already in space and many more far along in development.

RFK Jr.’s CDC may limit COVID shots to 75 and up, claim they killed kids

RFK Jr.’s CDC may limit COVID shots to 75 and up, claim they killed kids

fivenewscrypto    septembre 15, 2025   

Under ardent anti-vaccine activist Robert F. Kennedy Jr, federal health officials are working to link COVID-19 mRNA vaccines to the deaths of 25 children, and may further restrict access to the shots, possibly recommending them for people aged 75 and up, instead of 65 and up, according to The Washington Post.

Four unnamed sources close to the situation told the Post that Trump administration health officials appear to be using information from the Vaccine Adverse Event Reporting System (VAERS) to make the claim that COVID-19 vaccines have killed children. VAERS is a system in which anyone can report anything they think is an adverse event related to a vaccination. The reports are completely unverified upon submission, and the Centers for Disease Control and Prevention staff follow up on serious reports to try to substantiate claims and assess if they were actually caused by a vaccine. They rarely are.

Vaccine safety

Federal health experts continuously monitor VAERS and other safety surveillance systems, exhaustively assessing the safety of vaccines. After billions of COVID-19 doses have been administered worldwide, they—like other governments, health organizations, and academic researchers around the world—have found the shots to be remarkably safe. While they have been linked to a risk of myocarditis and pericarditis (inflammation of the heart and surrounding tissue, respectively), that risk is low and the cases are generally mild. During the 2023–2024 COVID-19 season, the incidence rate of heart conditions was 27 cases per million doses for males aged 12 to 24, who have the highest risk of any group. The shots have not been linked to deaths or heart transplants, according to data presented by staff experts at the CDC.
