The US military launched a long-range hypersonic missile Friday morning from Cape Canaveral Space Force Station in Florida on a test flight that, if successful, could pave the way for the weapon's operational deployment later this year.

The Army's Long-Range Hypersonic Weapon fired out of a canister on a road-mobile trailer shortly after sunrise on Florida's Space Coast, then headed east over the Atlantic Ocean propelled by a solid-fueled rocket booster. Local residents shared images of the launch on social media.

Designed for conventional munitions, the new missile is poised to become the first ground-based hypersonic weapon fielded by the US military. Russia has used hypersonic missiles in combat against Ukraine. China has "the world's leading hypersonic missile arsenal," according to a recent Pentagon report on Chinese military power. After a successful test flight from Cape Canaveral last year, the long-range hypersonic weapon (LRHW)—officially named "Dark Eagle" by the Army earlier this week—will give the United States the ability to strike targets with little or no warning.

As of Friday, April 25, the US has confirmed over 900 measles cases since the start of the year. The cases are across 29 states, but most are in or near Texas, where a massive outbreak continues to mushroom in close-knit, undervaccinated communities.

On April 24, the Centers for Disease Control and Prevention had tallied 884 cases across the country. Today, the Texas health department updated its outbreak total, adding 22 cases to its last count from Tuesday. That brings the national total to at least 906 confirmed cases. Most of the cases are in unvaccinated children and teens.

Overall, Texas has identified 664 cases since late January. Of those, 64 patients have been hospitalized, and two unvaccinated school-aged children with no underlying medical conditions have died of the disease. An unvaccinated adult in New Mexico also died from the infection, bringing this year's measles death toll to three.

A lawyer representing MyPillow and its CEO Mike Lindell in a defamation case admitted using artificial intelligence in a brief that has nearly 30 defective citations, including misquotes and citations to fictional cases, a federal judge said.

"[T]he Court identified nearly thirty defective citations in the Opposition. These defects include but are not limited to misquotes of cited cases; misrepresentations of principles of law associated with cited cases, including discussions of legal principles that simply do not appear within such decisions; misstatements regarding whether case law originated from a binding authority such as the United States Court of Appeals for the Tenth Circuit; misattributions of case law to this District; and most egregiously, citation of cases that do not exist," US District Judge Nina Wang wrote in an order to show cause Wednesday.

Wang ordered attorneys Christopher Kachouroff and Jennifer DeMaster to show cause as to why the court should not sanction the defendants, law firm, and individual attorneys. Kachouroff and DeMaster also have to explain why they should not be referred to disciplinary proceedings for violations of the rules of professional conduct.

There's a curious contradiction at the heart of today's most capable AI models that purport to "reason": They can solve routine math problems with impressive accuracy, yet when faced with formulating deeper mathematical proofs found in competition-level challenges, they often fail.

That's the finding of eye-opening preprint research into simulated reasoning (SR) models, initially listed in March and updated in April, that mostly fell under the news radar. The research serves as an instructive case study on the mathematical limitations of SR models, despite sometimes grandiose marketing claims from AI vendors.

What sets simulated reasoning models apart from traditional large language models (LLMs) is that they have been trained to output a step-by-step "thinking" process (often called "chain-of-thought") to solve problems. Note that "simulated" in this case doesn't mean that the models do not reason at all but rather that they do not necessarily reason using the same techniques as humans. That distinction is important because human reasoning itself is difficult to define.

If I knew how much I’d end up loving my Logitech mice, I would’ve taken better care of them from the start. The MX Master 3S and Lift are my favorite mice for productivity, but their rubber coating can get grimy quickly. My white MX Master 3S looks especially shameful atop my desk, so I’ve been considering purchasing a replacement for a while.

Overturning my plans, though, Logitech recently raised prices across 51 percent of its portfolio, as detailed by YouTube channel Cameron Doughterty Tech. The firm has raised prices by as much as 25 percent.

The MX Master 3S I just mentioned is now $120, which is $20 more than before. That 20 percent increase makes it even harder to justify a new mouse, which I already considered a luxury purchase.

What does the "typical" exosolar system look like? We know it's not likely to look like our own Solar System, given that our familiar planets don't include entire classes of planets (Hot Jupiters! Mini-Neptunes!) that we've found elsewhere. And our discovery methods have been heavily biased toward planets that orbit close to their host star, so we don't really have a strong sense of what might be lurking in more distant orbits.

A new study released on Thursday describes a search for what are called "microlensing" events, where a planet acts as a gravitational lens that magnifies the star it's orbiting, causing it to brighten briefly. These events are difficult to capture, but can potentially indicate the presence of planets in more distant orbits. The researchers behind the new work find indications that there's a significant population of rocky super-Earths that are traveling in orbits similar to that of Jupiter and Saturn.

Lenses go micro

The two primary methods we've used to discover exoplanets are called transit and radial velocity. In the transit method, we simply watch the star for dips in the light it sends to Earth, which can be an indication of a planet orbiting in a way that it eclipses a small fraction of the star. For radial velocity, we look for red- or blue-shifts in the light received from the star, caused by a planet tugging the star in different directions as it orbits.

Multiple studies and investigations have found that about half of American households watch TV and movies with subtitles on, but only a relatively small portion of those include someone with a hearing disability. That's because of the trouble many people have understanding dialogue in modern viewing situations, and Netflix has now introduced a subtitles option to help.

The closed captioning we've all been using for years includes not only the words the people on-screen are saying, but additional information needed by the hard of hearing, including character names, music cues ("dramatic music intensifies") and sound effects ("loud explosion").

For those who just wanted to make sure they didn't miss a word here and there, the frequent descriptions of sound effects and music could be distracting. This new format omits those extras, just including the spoken words and nothing else—even in the same language as the spoken dialogue.

The FBI is offering $10 million for information about the China-state hacking group tracked as Salt Typhoon and its intrusion last year into sensitive networks belonging to multiple US telecommunications companies.

Salt Typhoon is one of a half-dozen or more hacking groups that work on behalf of the People’s Republic of China. Intelligence agencies and private security companies have concluded the group has been behind a string of espionage attacks designed to collect vital information, in part for use in any military conflicts that may arise in the future.

A broad and significant cyber campaign

The agency on Thursday published a statement offering up to $10 million, relocation assistance, and other compensation for information about Salt Typhoon. The announcement specifically sought information about the specific members of Salt Typhoon and the group's compromise of multiple US telecommunications companies last year.

Microsoft’s Copilot+ PC platform was predicated on the idea that Windows computers with processors that have newfangled neural processing units would be able to do all sorts of nifty things with AI. But the most impressive features that Microsoft promised have been slow to arrive… after the company faced backlash over the potential privacy and […]

Elon Musk raced to build Colossus, the world's largest supercomputer, in Memphis, Tennessee. He bragged that construction only took 122 days and expected that his biggest AI rivals would struggle to catch up.

To leap ahead, his firm xAI "removed whatever was unnecessary" to complete the build, questioning "everything" that might delay operations and taking the timeline "into our own hands," xAI's website said.

Now, xAI is facing calls to shut down gas turbines that power the supercomputer, as Memphis residents in historically Black communities—which have long suffered from industrial pollution causing poor air quality and decreasing life expectancy—allege that xAI has been secretly running more turbines than the local government knows, without permits.
