From the how-about-that department: Razer will have to fork over $1.1 million in refunds to customers who purchased its RGB-clad Zephyr face mask, according to a proposed settlement announced by the Federal Trade Commission on Monday. From a report: The company claimed the face mask used N95-grade filters, but the FTC alleges Razer never submitted them for testing and only "stopped the false advertising following negative press coverage and consumer outrage at the deceptive claims."
Razer first released its Zephyr face mask in 2021 as a nifty, cyberpunk-esque alternative to traditional face masks worn during the covid-19 pandemic. Although Razer initially marketed the $100 mask as having N95-grade filters, it scrubbed any mention of the grade after YouTuber Naomi Wu tore down the mask and found that it wasn't N95 certified after all. N95 masks are supposed to filter out at least 95 percent of airborne particles, according to the Centers for Disease Control and Prevention. Razer also planned on launching a $150 Zephyr Pro with a voice amplification feature, but that never panned out. At the time, Razer addressed claims about its Zephyr masks, saying in a post on X that "the Razer Zephyr and Zephyr Pro are not medical devices, respirators, surgical masks, or personal protective equipment (PPE) and are not meant to be used in medical or clinical settings."

From the truckin' department: Oakland, California is now home to "the first commercial hydrogen fuel station for big-rig trucks in the United States," according to the Los Angeles Times — serving 30 hydrogen fuel-cell trucks.
The newspaper says the facility "could mark the start of a nationwide network for fuel-cell truck refueling. It could also flop."
Hydrogen fuel is expensive — as much as four times more expensive than gasoline or diesel fuel. The fuel cells, which drive electric motors to drive the truck, are enormously expensive as well.... The vehicles themselves are expensive too. Both battery electric and hydrogen fuel-cell trucks can cost three times as much or more than a $120,000 diesel truck. Those buying the trucks can qualify for state and federal subsidies to make up most of the upfront costs.
But government regulations may spark some demand:
New diesel truck sales will be outlawed in California by 2036. Only zero-tailpipe-emission new trucks will be allowed. Already, zero-emission requirements are in place for trucks that enter ocean ports. And only two technologies are available to achieve that goal: battery electric trucks and hydrogen fuel-cell trucks. "We believe a good portion of those will be hydrogen vehicles," said Matt Miyasato, chief of public policy for hydrogen fuel distributor FirstElement Fuel. FirstElement, through its True Zero brand fueling stations, is the largest hydrogen vehicle fuel distributor in the U.S...
Battery electric is gaining a strong foothold in the medium-sized delivery truck market, but hydrogen could have a leg up for long-haul trucking. While a fuel cell is comparable in size to a diesel engine, a battery big enough for long-haul trucks adds weight and size and cuts down on the total freight load the truck can deliver. And while an electric truck battery can take hours to recharge, the refill time for hydrogen is more comparable to filling up with diesel fuel.

From the recurring-nova department: RockDoctor (Slashdot reader #15,477) wants to tell you about a "new" star that will be visible to the naked eye — without a telescope — sometime before September:
By "star", I do not mean "comet", "meteorite" or "firefly", but genuine [star] photons arriving here after about 3000 years in flight, causing your eyes to see a bright point on the nighttime sky. When it happens, the star will go from needing-a- telescope-or-good-binoculars-to-see, to being the 50th (or even 30th) brightest star in the sky.
For a week or so. Of course, it could just go full-on supernova, and be visible in daylight for a few weeks, and dominate the night sky for months. But that's unlikely.
Named "T Corona Borealis" (because it's the 20th variable star studied in the constellation "Corona Borealis") it's now visible all night, all year, for about 60% of the world's population (although normally you need binoculars to see it).
But RockDoctor writes that in 2016, "T CrB" (as it is known) has started showing "a similar pattern of changes" to what happened in the late 1930s when it became one of only 10 "recurring nova" known to science:
In 2023, the pattern continued and the match of details got better. The star is expected to undergo another "eruption" — becoming one of the brightest few stars in the sky, within the next couple of months. Maybe the next couple of weeks. Maybe the next couple of hours....
