Mars is back on the agenda.

During his address to a joint session of Congress in March, President Donald Trump said the United States "will pursue our Manifest Destiny into the stars, launching American astronauts to plant the Stars and Stripes on the planet Mars."

What does this mean? Manifest destiny is the belief, which was particularly widespread in 1800s America, that US settlers were destined to expand westward across North America. Similarly, then, the Trump administration believes it is the manifest destiny of Americans to settle Mars. And he wants his administration to take steps toward accomplishing that goal.

On Monday, OpenAI announced the GPT-4.1 model family, its newest series of AI language models that brings a 1 million token context window to OpenAI for the first time and continues a long tradition of very confusing AI model names. Three confusing new names, in fact: GPT‑4.1, GPT‑4.1 mini, and GPT‑4.1 nano.

According to OpenAI, these models outperform GPT-4o in several key areas. But in an unusual move, GPT-4.1 will only be available through the developer API, not in the consumer ChatGPT interface where most people interact with OpenAI's technology.

The 1 million token context window—essentially the amount of text the AI can process at once—allows these models to ingest roughly 3,000 pages of text in a single conversation. This puts OpenAI's context windows on par with Google's Gemini models , which have offered similar extended context capabilities for some time.

In one way or another, the Lunar Gateway has lingered around the periphery of NASA's human exploration program since the Obama administration.

Back then, the elements that eventually coalesced into the Gateway were geared toward a nebulous initiative to capture a small asteroid and reposition it closer to Earth. Under direction from the first Trump administration, NASA ditched the asteroid idea and repackaged the concept to become a mini-space station in orbit around the Moon.

NASA officials justified the Lunar Gateway program by highlighting its utility as a staging point or safe haven for astronauts traveling to and from the surface of the Moon. Crews could launch from Earth and travel to the Moon's vicinity inside NASA's Orion spacecraft, connect with the Gateway, and then float into their lunar lander already docked with the outpost.

Razer, maker of green-hued gaming hardware and accessories, has entered the game-streaming space with its new—but not entirely new—app, PC Remote Play . It's based on very good existing streaming tech and makes connecting a PC to mobile devices fairly simple. It's worth checking out unless you have a hard-and-fast policy about avoiding software "utilities" from RGB-obsessed gaming companies.

That, or you're already using and comfortable with Moonlight . Moonlight and Sunshine are the open source game-streaming client and server that wonderfully picked up where Nvidia's Gamestream left off . PC Remote Play is based on Moonstream's open source code, and Razer has made much of its own version's code available .

You're getting a few small upgrades when using PC Remote Play:

The Li-ion batteries that power everything from smartphones to electric cars are usually packed in rigid, sealed enclosures that prevent stresses from damaging their components and keep air from coming into contact with their flammable and toxic electrolytes. It’s hard to use batteries like this in soft robots or wearables, so a team of scientists at the University California, Berkeley built a flexible, non-toxic, jelly-like battery that could survive bending, twisting, and even cutting with a razor.

While flexible batteries using hydrogel electrolytes have been achieved before, they came with significant drawbacks. “All such batteries could [only] operate [for] a short time, sometimes a few hours, sometimes a few days,” says Liwei Lin, a mechanical engineering professor at UC Berkeley and senior author of the study. The battery built by his team endured 500 complete charge cycles—about as many as the batteries in most smartphones are designed for.

Power in water

“Current-day batteries require a rigid package because the electrolyte they use is explosive, and one of the things we wanted to make was a battery that would be safe to operate without this rigid package,” Lin told Ars. Unfortunately, flexible packaging made of polymers or other stretchable materials can be easily penetrated by air or water, which will react with standard electrolytes, generating lots of heat, potentially resulting in fires and explosions. This is why, back in 2017, scientists started to experiment with quasi-solid-state hydrogel electrolytes.

Starting the Federal Trade Commission (FTC) antitrust trial Monday with a bang, Daniel Matheson, the FTC's lead litigator, flagged a "smoking gun"—a 2012 email where Mark Zuckerberg suggested that Facebook could buy Instagram to "neutralize a potential competitor," The New York Times reported .

And in "another banger of an email from Zuckerberg," Brendan Benedict, an antitrust expert monitoring the trial for Big Tech on Trial, posted on X that the Meta CEO wrote, "Messenger isn't beating WhatsApp. Instagram was growing so much faster than us that we had to buy them for $1 billion... that's not exactly killing it."

These messages and others, the FTC hopes to convince the court, provide evidence that Zuckerberg runs Meta by the mantra "it's better to buy than compete"—seemingly for more than a decade intent on growing the Facebook empire by killing off rivals, allegedly in violation of antitrust law. Another message from Zuckerberg exhibited at trial, Benedict noted on X, suggests Facebook tried to buy yet another rival, Snapchat, for $6 billion.

Samsung began the process of updating millions of smartphones around the world to its latest One UI 7 ( Android 15 ) software last week, but that process has now been halted. Over the weekend, Samsung purged the One UI 7 update from its servers, which indicates that a serious problem has occurred. The company isn't offering any explanation for the pause yet, but reports around the Internet suggest there are some bugs problematic enough that it required Samsung to slam on the brakes.

This update was destined for the Galaxy S24, Z Fold 6, and Z Flip 6, all of which launched with One UI 6 (Android 14). Samsung promises seven years of update support like Google, but it takes longer for it to release new operating system versions. Not only does Samsung modify the way Android looks, but it also integrates a raft of Galaxy AI features with Android. It takes time to do that—seven months and counting since Android 15's release—but it seems Samsung should have spent a little more time testing all those changes.

As soon as Samsung began the rollout on April 7, Galaxy S24 users in Korea noticed their phones would intermittently refuse to unlock, as reported by frequent Samsung leaker IceUniverse. There are also reports that Samsung's supposedly private Secure Folder has a bug in One UI 7 that can see photos from the gallery appear in auto-generated Stories. These Stories are accessible from outside the Secure Folder, which rather defeats the purpose of having private photos.

Apple is taking another crack at iPad multitasking, according to a report from Bloomberg's Mark Gurman. This year's iPadOS 19 release, due to be unveiled at Apple's Worldwide Developers Conference on June 9 , will apparently include an "overhaul that will make the tablet's software more like macOS."

The report is light on details about what's actually changing, aside from a broad "focus on productivity, multitasking, and app window management." But Apple will apparently continue to stop short of allowing users of newer iPads to run macOS on their tablets, despite the fact that modern iPad Airs and Pros use the same processors as Macs.

If this is giving you déjà vu, you're probably thinking about iPadOS 16 , the last time Apple tried making significant upgrades to the iPad's multitasking model. Gurman's reporting at the time even used similar language, saying that iPads running the new software would work " more like a laptop and less like a phone ."

Nvidia announced plans today to manufacture AI chips and build complete supercomputers on US soil for the first time, commissioning over one million square feet of manufacturing space across Arizona and Texas. The politically timed move comes amid rising US-China tensions and the Trump administration's push for domestic manufacturing.

Nvidia's announcement comes less than two weeks after the Trump administration's chaotic rollout of new tariffs and just two days after the administration's contradictory messages on electronic component exemptions.

On Friday night, the US Customs and Border Protection posted a bulletin exempting electronics including smartphones, computers, and semiconductors from Trump's steep reciprocal tariffs. But by Sunday, Trump and his commerce secretary Howard Lutnick contradicted this move, claiming the exemptions were only temporary and that electronics would face new "semiconductor tariffs" in the coming months .
