To the south of the Monte Cristo mountain range and west of Paymaster Canyon, a vast stretch of the Nevada desert has attracted modern-day prospectors chasing one of 21st-century America’s greatest investment booms.

Solar power developers want to cover an area larger than Washington, DC, with silicon panels and batteries, converting sunlight into electricity that will power air conditioners in sweltering Las Vegas along with millions of other homes and businesses.

But earlier this month, bureaucrats in charge of federal lands scrapped collective approval for the Esmeralda 7 projects, in what campaigners fear is part of an attack on renewable energy under President Donald Trump. “We will not approve wind or farmer destroying [sic] Solar,” he posted on his Truth Social platform in August. Developers will need to reapply individually, slowing progress.

There has been much discussion in the space community recently about building large data centers in orbit to avoid the environmental consequences of sprawling computing facilities on Earth. These space-based data centers could take advantage of the always-on, free fusion reactor at the center of the Solar System.

Proponents say this represents a natural step in the evolution of moving heavy industry off the planet’s surface and a solution for the ravenous energy needs of artificial intelligence. Critics say building data centers in space is technically very challenging and cite major hurdles, such as radiating away large amounts of heat and the cost of accessing space.

It is unclear who is right, but one thing is certain: Such facilities would need to be massive to support artificial intelligence.

Just a few weeks ago, automakers were celebrating a healthy third quarter for electric vehicle sales. General Motors was looking particularly flush, with EV sales up 104 percent for the year to date compared to the first nine months of 2024. But the strong EV sales in Q3 were seemingly due to the imminent end of the federal tax credit that expired at the end of September , with many consumers buying a car sooner than planned to take advantage of the $7,500 incentive.

The Trump administration has been altering the regulatory environment in other ways to discourage clean technologies, canceling infrastructure initiatives and turning a blind eye to pollution . On top of that, the impact of the president’s chaotic trade war has driven up prices and is cooling demand. Two weeks ago, GM told investors that things are looking so bad that it will take a $1.6 billion hit to its bank accounts as it realigns manufacturing capacity going forward.

Now we can see some of the impact of that realignment. According to The Detroit News , 1,200 workers are being laid off at GM’s EV-building Hamtramck Assembly Center near Detroit, which will move from two shifts a day to just one in early January.

It’s spooky season, and what better way to spend Halloween weekend than settling in to watch a classic Hollywood ghost story? To help you figure out what to watch, we’ve compiled a handy list of 15 classic ghost stories, presented in chronological order.

What makes a good ghost story? Everyone’s criteria (and taste) will differ, but for this list, we’ve focused on more traditional elements. There’s usually a spooky old house with a ghostly presence and/or someone who’s attuned to said presence. The living must solve the mystery of what happened to trap the ghost(s) there in hopes of setting said ghost(s) free. In that sense, the best, most satisfying ghost stories are mysteries—and sometimes also love stories . The horror is more psychological, and when it comes to gore, less is usually more.

As always, the list below isn’t meant to be exhaustive. Mostly, we’re going for a certain atmospheric vibe to set a mood. So our list omits overt comedies like Ghostbusters and (arguably) Ghost , as well as supernatural horror involving demonic possession— The Exorcist, The Conjuring , Insidious— or monsters, like The Babadook or Sinister . Feel free to suggest your own recommendations in the comments.

Researchers and users of LLMs have long been aware that AI models have a troubling tendency to tell people what they want to hear , even if that means being less accurate. But many reports of this phenomenon amount to mere anecdotes that don’t provide much visibility into how common this sycophantic behavior is across frontier LLMs.

Two recent research papers have come at this problem a bit more rigorously, though, taking different tacks in attempting to quantify exactly how likely an LLM is to listen when a user provides factually incorrect or socially inappropriate information in a prompt.

Solve this flawed theorem for me

In one pre-print study published this month, researchers from Sofia University and ETH Zurich looked at how LLMs respond when false statements are presented as the basis for difficult mathematical proofs and problems. The BrokenMath benchmark that the researchers constructed starts with “a diverse set of challenging theorems from advanced mathematics competitions held in 2025.” Those problems are then “perturbed” into versions that are “demonstrably false but plausible” by an LLM that’s checked with expert review.

The outage that hit Amazon Web Services and took out vital services worldwide was the result of a single failure that cascaded from system to system within Amazon’s sprawling network, according to a post-mortem from company engineers.

The series of failures lasted for 15 hours and 32 minutes, Amazon said . Network intelligence company Ookla said its DownDetector service received more than 17 million reports of disrupted services offered by 3,500 organizations. The three biggest countries where reports originated were the US, the UK, and Germany. Snapchat, AWS, and Roblox were the most reported services affected. Ookla said the event was “among the largest internet outages on record for Downdetector.”

It’s always DNS

Amazon said the root cause of the outage was a software bug in software running the DynamoDB DNS management system. The system monitors the stability of load balancers by, among other things, periodically creating new DNS configurations for endpoints within the AWS network. A race condition is an error that makes a process dependent on the timing or sequence events that are variable and outside the developers’ control. The result can be unexpected behavior and potentially harmful failures.

A 61-year-old man in California is lucky to be alive after a combination of herbal supplements he was taking for joint pain ended up utterly wrecking his body, landing him in intensive care and in a delirious state for months. His case is reported in the Annals of Internal Medicine: Clinical Cases .

The man turned up at a hospital in San Francisco in bad shape, but with nonspecific problems that had begun just two days earlier. His back hurt, he was feverish, nauseous, bloated, and he hadn’t been eating much. He was so weak he couldn’t walk or get out of bed without help. His heart rate and breathing rate were high. His blood pressure was low. There were multiple wounds on his lower body in various stages of healing.

Initial exams and lab work revealed Staphylococcus aureus bacteria in his blood. There was also an abscess on his shoulder and an infection in and around his spine, which was worsening. Doctors wanted to perform a surgical procedure to relieve the pressure building up on his spinal cord and nerves, but his blood pressure was too low—and then he went into hemorrhagic shock from bleeding in his gastrointestinal tract. Doctors transferred him to the intensive care unit.

One of the things that emerging diseases, including the COVID and Zika pandemics, have taught us is that it’s tough to keep up with infectious diseases in the modern world. Things like air travel can allow a virus to spread faster than our ability to develop therapies. But that doesn’t mean biotech has stood still; companies have been developing technologies that could allow us to rapidly respond to future threats.

There are a lot of ideas out there. But this week saw some early clinical trial results of one technique that could be useful for a range of infectious diseases. We’ll go over the results as a way to illustrate the sort of thinking that’s going on, along with the technologies we have available to pursue the resulting ideas.

The best antibodies

Any emerging disease leaves a mass of antibodies in its wake—those made by people in response to infections and vaccines, those made by lab animals we use to study the infectious agent, and so on. Some of these only have a weak affinity for the disease-causing agent, but some of them turn out to be what are called “broadly neutralizing.” These stick with high affinity not only to the original pathogen, but most or all of its variants, and possibly some related viruses.

Digital reading devices like the Kindle have existed for almost 20 years, and the standard eReader form factor has hardly changed at all. Amazon, Boox, and a few other companies have offered larger E Ink screens, but how about something smaller? Boox has unveiled its second-generation Palma e-reader, which still fits in your pocket but adds a color screen and mobile data connectivity.

The first-gen Palma launched last year, earning fans who saw it as a way to read and access some apps without the full spate of distracting smartphone experiences. Boox e-readers are essentially Android tablets with E Ink screens and a few software quirks that arise from their unofficial Google Play implementation. The second-gen Palma might offer more opportunities for distraction because it’s almost a smartphone.

The Palma 2 Pro upgrades the 6.1-inch monochrome display from the original to a 6.13-inch color E Ink Kaleido display. That’s the same technology used in Amazon’s Kindle Colorsoft . The Amazon reader is a bit larger with its 7-inch display and chunkier bezels. Of course, the Kindle isn’t trying to fit in your pocket like the Palma 2 Pro, which is roughly the size and shape of a phone.
