Los Alamos is capturing real-time images of explosions at 7mths of a second

Download a print-friendly version of this article. Los Alamos scientists are good at doing things that seem impossible, like taking a picture of something that happens in less than seven-millionths of a second—such as an explosion. And not just one picture, but a series of images that reveal pivotal data about the material that exploded and the physics of the explosion. This so-called dynamic imaging is essential to the Lab’s stockpile stewardship mission because it helps scientists test and un

US Coast Guard Report on Titan Submersible

WASHINGTON — The U.S. Coast Guard Marine Board of Investigation (MBI) released its Report of Investigation (ROI) Tuesday on the loss of the Titan submersible, which imploded during a June 2023 dive to the Titanic, killing five people. The more than 300-page ROI outlines key findings and contributing factors in the casualty and includes 17 safety recommendations aimed at strengthening oversight of submersible operations, improving coordination among federal agencies and closing gaps in internati

Four radioactive wasp nests found on South Carolina nuclear facility

Wasps living around a Cold War-era nuclear facility in South Carolina have built at least four radioactive nests, raising questions about their source of hazardous material and the extent of environmental contamination, according to a report by The New York Times. Last week, news broke that officials at the site—Savannah River Site (SRS) near Aiken, South Carolina—had found one radioactive nest on July 3. The discovery was documented in a July 22 report by the US Department of Energy, which own

Yosemite embodies the long war over US national park privatization

The Trump administration’s cuts to the National Park Service’s budget and staffing have raised concerns among park advocates and the public that the administration is aiming to further privatize the national parks. The nation has a long history of similar efforts, including a wildly unpopular 1980 attempt by Reagan administration Interior Secretary James Watt to promote development and expand private concessions in the parks. But debate over using public national park land for private profit da

Show HN: NaturalCron – Human-Readable Scheduling for .NET (With Fluent Builder)

NaturalCron NaturalCron is a human-readable scheduling engine for .NET. It lets you write schedules in a clear and intuitive way instead of memorizing cryptic cron strings. Why? Because memorizing 0 18 * * 1-5 is harder than understanding every day between monday and friday at 6:00pm . Readable schedules reduce mistakes, write expressions that you can understand at a glance. Note: NaturalCron is not a cron converter. It’s a new expressive syntax for better readability. 💡 Why use NaturalCron

Hibernation’s Hidden Healing ‘Superpowers’ Could Be Locked in Our DNA

After spending months without eating, drinking, or moving, hibernating mammals must rebound from extreme physiological changes. Two new studies suggest that the genetic “superpowers” underlying this incredible resilience may also be present in the human genome. For these studies, published Thursday, July 31, in the journal Science, researchers at the University of Utah honed in on the specific DNA regions that help hibernators rapidly recover from muscle atrophy, insulin resistance, and brain d

Radioactive Wasp Nest Found in Decommissioned Nuclear Weapons Plant

As if wasps couldn’t get any scarier, a chilling discovery near Aiken, South Carolina, suggests they’re comfortable making their nest in a former nuclear bomb facility. On July 3, employees conducting a regular checkup of radiation levels at the Savannah River Site (SRS)—a former nuclear weapons production facility dating back to the 1950s—found themselves staring down at something that probably should not have been there. That something was a wasp nest measuring more than 10 times the federall

Trump will end the de minimis exemption for low-cost global shipments

President Donald Trump's latest economic move is to halt the de minimis exemption, a provision that made international shipments of low-value items cheaper. When the exemption ends on August 29, shipments valued at or under $800 will be subject to duty fees when sent by any carrier other than the international postal network, no matter what country they are coming from. According to the White House's announcement of this change, shipments will either be assessed with an ad valorem duty equal to

Minnesota activates National Guard as cyberattack on Saint Paul disrupts public services

Minnesota Gov. Tim Walz has activated the state’s National Guard following a cyberattack on the state’s capital, Saint Paul. City officials have not yet disclosed the nature of the cyberattack, but the July 25 breach continues to disrupt city operations and some public services.

Trump caving on Nvidia H20 export curbs may disrupt his bigger trade war

The next front in Donald Trump's trade war will be chip tariffs—which could come by next month—but national security experts are warning that the president may have already made a huge misstep that threatens to disrupt both US trade and national security. In a letter Monday to Department of Commerce Secretary Howard Lutnick, 20 policymakers and professionals with a background in national security policy urged Trump to reverse course and block exports of Nvidia's H20 chips to China. In April, t

2025 Polestar 3 drives sporty, looks sharp, can be a little annoying

Earlier this month, Ars took a look at Volvo’s latest electric vehicle. The EX90 proved to be a rather thoughtful Swedish take on the luxury SUV, albeit one that remains a rare sight on the road. But the EX90 is not the only recipe one can cook with the underlying ingredients. The ingredients in this case are from a platform called SPA2, and to extend the metaphor a bit, the kitchen is the Volvo factory in Ridgeville, South Carolina, which in addition to making a variety of midsize and larger Vo
