Another AT&T FirstNet user gets shocking $6,200 bill, at $2 per megabyte

Another AT&T FirstNet user gets shocking $6,200 bill, at $2 per megabyte

If you're an AT&T FirstNet customer and suddenly get hit with a $6,200 charge, the good news is that it's probably a mistake and can be corrected. But actually getting the wrong charge wiped out might not be so easy.

This has now happened at least twice. In December 2024, a Texas police officer received a $6,223 bill with a $6,194 charge for using 3.1GB of data. He said he had unlimited data but was charged incorrectly after moving a line to AT&T's FirstNet service for first responders. He called AT&T and went to an AT&T store but only got the bill reversed after contacting the AT&T president’s office.

An AT&T spokesperson told Ars at the time that it was "investigating to determine what caused this system error." But AT&T never revealed exactly what caused it, and now another FirstNet user has gone through an almost identical ordeal.

Subscribers to Amazon Prime Video with ads lose 4K support on April 10

Subscribers to Amazon Prime Video with ads lose 4K support on April 10

fivenewscrypto    mars 15, 2026   

Starting on April 10, Amazon Prime subscribers will pay $5 per month for ad-free Prime Video without ads, up from the current $3 per month on top of their Prime subscription, Amazon announced today.

On that date, Amazon will introduce a new ad-free Prime Video subscription tier called “Prime Video Ultra.” Amazon will also increase the number of simultaneous streams supported by the tier from three to five and the number of downloads permitted from 25 to 100.

Currently, Prime Video with ads is part of Amazon’s Prime membership, which starts at $15 a month. Today, ad-free Prime Video users can watch supported titles in 4K, but starting on April 10, a new Prime Video Ultra subscription will be required for 4K viewing.

M5 MacBook Air review: Still the best MacBook for almost everybody

M5 MacBook Air review: Still the best MacBook for almost everybody

fivenewscrypto    mars 14, 2026   

The M5 Pro and M5 Max in the new MacBook Pros are interesting not because they deliver a solid speed increase for Apple's fastest laptop processors but because they also include substantial under-the-hood changes. And the MacBook Neo is interesting because, while the hardware has limits, it's quite a capable and high-quality computer for its $599 starting price.

And then there's the M5 MacBook Air, which was also released this week.

Apple sent us a 16-inch M5 Max MacBook Pro, the MacBook Neo, and a 15-inch MacBook Air to test, and the MacBook Air was the only one without a standard review embargo. As if to say, "we know the other stuff is more interesting—if you want to cover the Air, get to it when you can."

Magnetars drag spacetime to power superluminous supernovae

Magnetars drag spacetime to power superluminous supernovae

fivenewscrypto    mars 14, 2026   

Some of the most extreme explosions in the universe are Type I superluminous supernovae. “They are one of the brightest explosions in the Universe,” says Joseph Farah, an astrophysicist at the University of California, Santa Barbara. For years, astrophysicists tried to understand what exactly makes superluminous supernovae so absurdly powerful. Now it seems like we may finally have some answers.

Farah and his colleagues have found that these events are most likely powered by magnetars, rapidly spinning neutron stars that warp the very space and time around them.

The power within

Magnetars have been a leading candidate for the engine behind superluminous supernovae. The theory says these insanely magnetized stars are born from the collapsing core of the original progenitor star and emit energy via magnetic dipole radiation. “This core is roughly a one solar mass object that gets crushed down to the size of a city,” Farah explains. As its spin slows down, a magnetar bleeds its rotational energy into the expanding material of the dead star, lighting it up.

Measles vaccinations rose 291% among New Mexico adults during outbreak

Measles vaccinations rose 291% among New Mexico adults during outbreak

fivenewscrypto    mars 14, 2026   

In January 2025, a measles outbreak erupted on the western edge of Texas and soon spilled over to New Mexico and other states. The overall outbreak would become the largest the country has seen since 2000, when measles was declared eliminated from the US. In Texas, it was the largest outbreak recorded since 1992. And in New Mexico, it was the first measles outbreak the state had even seen since 1996.

But the trajectory of the two states' measles cases diverged. Texas declared the outbreak within its borders over on August 18, with an end tally of 762 cases. In New Mexico, officials declared its outbreak, which began in February, over on September 26, with a total of just 99 cases.

One of the key differences, according to a new study, was that in New Mexico, the rapid spread of the highly infectious virus spurred a massive surge in measles vaccinations among children and adults. Overall, shots of the measles, mumps, and rubella (MMR) vaccine increased 55 percent statewide from January to September compared to the same period in 2024.

Microsoft is working to eliminate PC gaming's "compiling shaders" wait times

Microsoft is working to eliminate PC gaming's "compiling shaders" wait times

fivenewscrypto    mars 14, 2026   

Modern gamers are used to loading up a new game for the first time and being forced to wait multiple minutes while a "compiling shaders" step whirs away, optimizing advanced 3D effects for their specific hardware. This week at the Game Developers Conference, Microsoft provided some updates about its Advanced Shader Delivery for Windows efforts, which are designed to fix the problem by generating collections of precompiled shaders that can be downloaded ahead of time.

In a console environment, developers can optimize and precompile their graphics shaders to work well with a set driver and GPU environment. On PC, though, developers tend to leave their shaders as uncompiled code that can then be compiled and cached at runtime based on the specific hardware and drivers on the player's machine.

Microsoft's Advanced Shader Delivery infrastructure aims to fix this problem by automating the process of precompiling shaders that work across "a large matrix of drivers and GPUs in the Windows ecosystem," as the company puts it. To enable that, developers use Microsoft's Direct3D API to create a State Object Database (SODB) that represents in-game assets at the game engine level. That asset database is then fed into multiple shader compilers to create a Precompiled Shader Database (PSDB) that supports multiple display adapters from different hardware vendors.

Aliens announce their presence in latest Disclosure Day trailer

Aliens announce their presence in latest Disclosure Day trailer

fivenewscrypto    mars 14, 2026   

There are different marketing strategies when it comes to movie trailers. One is the Project Hail Mary approach, in which the final trailer pretty much gives away the entire movie, trusting that the audience will still come along for the ride because it's a sci-fi adventure, not a whodunnit. The other extreme is Universal Pictures' deliberately vague trailers for Disclosure Day, director Steven Spielberg's return to his "aliens are among us" roots, which give tantalizing hints about the basic premise and little more.

Per the official logline: “If you found out we weren’t alone, if someone showed you, proved it to you, would that frighten you? This summer, the truth belongs to 7 billion people. We are coming close to… Disclosure Day.”

As previously reported, David Koepp, who has worked with Spielberg on numerous projects (including Jurassic Park and War of the Worlds), wrote the screenplay, while John Williams composed the score. Emily Blunt stars as a TV meteorologist in Kansas City. Her co-stars include Josh O’Connor, Colin Firth, Eve Hewson, Colman Domingo, Wyatt Russell, Elizabeth Marvel, Henry Lloyd-Hughes, Michael Gaston, and Mckenna Bridger. Professional wrestlers Chavo Guerrero Jr., Lance Archer, and Brian Cage will also appear.
