Honda's motorsport division must be doing some spring cleaning. Today, the Honda Racing Corporation announced that it's getting into the memorabilia business, offering up parts and even whole vehicles for fans and collectors. And to kick things off, it's going to auction some components from the RA100E V10 engines that powered the McLaren Honda MP4/5Bs of Ayrton Senna and Gerhard Berger to both F1 titles in 1990.

"We aim to make this a valuable business that allows fans who love F1, MotoGP and various other races to share in the history of Honda's challenges in racing since the 1950s," said Koi Watanabe, president of HRC, "including our fans to own a part of Honda's racing history is not intended to be a one-time endeavor, but rather a continuous business that we will nurture and grow."

The bits from Senna's and Berger's V10s will go up for auction at Monterey Car Week later this year, and the lots will include some of the parts seen in the photo above: cam covers, camshafts, pistons, and conrods, with a certificate of authenticity and a display case. And HRC is going through its collections to see what else it might part with, including "heritage machines and parts" from IndyCar, and "significant racing motorcycles."

There are a remarkable number of commercial fusion power startups, considering that it's a technology that's built a reputation for being perpetually beyond the horizon. Many of them focus on radically new technologies for heating and compressing plasmas, or fusing unusual combinations of isotopes. These technologies are often difficult to evaluate—they can clearly generate hot plasmas, but it's tough to determine whether they can get hot enough, often enough to produce usable amounts of power.

On the other end of the spectrum are a handful of companies that are trying to commercialize designs that have been extensively studied in the academic world. And there have been some interesting signs of progress here. Recently, Commonwealth Fusion, which is building a demonstration tokamak in Massachussets, started construction of the cooling system that will keep its magnets superconducting. And two companies that are hoping to build a stellarator did some important validation of their concepts.

Doing donuts

A tokamak is a donut-shaped fusion chamber that relies on intense magnetic fields to compress and control the plasma within it. A number of tokamaks have been built over the years, but the big one that is expected to produce more energy than required to run it, ITER, has faced many delays and now isn't expected to achieve its potential until the 2040s. Back in 2015, however, some physicists calculated that high-temperature superconductors would allow ITER-style performance in a far smaller and easier-to-build package. That idea was commercialized as Commonwealth Fusion.

Nearly half of US states sued the federal government and Secretary of Health and Human Services Robert F. Kennedy Jr. today in a bid to halt the termination of $11 billion in public health grants. The lawsuit was filed by 23 states and the District of Columbia.

"The grant terminations, which came with no warning or legally valid explanation, have quickly caused chaos for state health agencies that continue to rely on these critical funds for a wide range of urgent public health needs such as infectious disease management, fortifying emergency preparedness, providing mental health and substance abuse services, and modernizing public health infrastructure," said a press release issued by Colorado Attorney General Phil Weiser.

The litigation is led by Colorado, California, Minnesota, Rhode Island, and Washington. The other plaintiffs are Arizona, Connecticut, Delaware, the District of Columbia, Hawaii, Illinois, Kentucky, Maine, Maryland, Massachusetts, Michigan, Nevada, New Jersey, New Mexico, New York, North Carolina, Oregon, Pennsylvania, and Wisconsin.

Apple spent years ignoring RCS, allowing iPhones to offer a degraded messaging experience with Android users. This made Android folks unwelcome in many a group chat, but Apple finally started rectifying this issue last year with the addition of RCS support in iOS. It has been a slow rollout, though, with Google's mobile service only now getting support.

While Apple supports RCS messaging on iPhones now, it has not exactly been enthusiastic about it. Anyone using Google Fi on an iPhone was left in the lurch even after Apple changed course. The first RCS update rolled out in iOS 18 last fall, but it only supported postpaid plans on the big three carriers. Everyone else was left waiting, including Google Fi, as confirmed to Ars last year. It was a suitably amusing outcome, considering Google is largely responsible for reviving the RCS standard and runs the Jibe back-end servers through which many iPhone RCS messages flow.

Slowly but surely, Apple is making good on its promises to enable RCS. The company released iOS 18.4 this week, and hiding amid the control center tweaks and priority notifications is support for RCS on Google Fi and other T-Mobile MVNOs. Some users spotted this feature in the recent beta releases, but the servers that handle RCS for Google's mobile service were not yet connectable. With the final release, Google has confirmed that RCS is ready at last.

With its planned Switch 2 Direct presentation scheduled for Wednesday morning, Nintendo is set to finally fully pull back the curtain on a console we've been speculating about for years now. We'll have plenty of reporting and analysis of whatever Nintendo announces in the days to come. In the meantime, though, we thought it would be fun to put down a marker on some of the key announcements we expect Nintendo to make tomorrow.

Rather than limiting ourselves to a single prediction, though, we've broken things down into increasingly outlandish categories of "Likely," "Possible," and "Implausible." Consider this an exercise in expectation-setting for one of the most important moments in Nintendo's recent history, and be sure to let us know what you think will happen in the comments section below.

Likely: A $399 MSRP would reflect some of the eight years of inflation-related erosion that Nintendo has seen in the (seemingly unmovable) $299 price of the original Switch. That price point would also put the Switch 2 at rough parity with the market-proven price point of the (older, non-portable) Xbox Series X and PS5.

In 1982, while most game developers were busy with space invaders and maze ghosts, Bill Williams created something far more profound: a game about swimming upstream against impossible odds. Salmon Run for the Atari 800 served as a powerful metaphor for life itself, one that resonates even more deeply when you learn about the creator's own struggles with cystic fibrosis.

As a kid growing up in the 1980s with an Atari 800 home computer, I discovered this hidden gem in our family's game collection, and it soon became a favorite. What struck me most—and what still amazes me today—was its incredible audio design, creating water sounds that seemed impossible for 8-bit hardware. But Salmon Run was about far more than impressive audio.

In the game, you play as Sam the Salmon, swimming upriver to spawn with a female salmon waiting upstream. You control your speed while dodging obstacles like rocks, waterfalls, and riverbanks, moving left to right and leaping from the water. And predators—bears, fishermen, and birds—are constantly trying to eat you.
