THE FUTURE ALWAYS HAPPENS FASTER THAN PREDICTED:

Fusion Energy: No Longer “30 Years Away”? (Noah El Alami, 4/28/25, IDTechX)

The largest funding rounds for commercial fusion occurred largely in the last 5 years. There are now around 50 private companies pursuing commercial fusion, with leaders in the industry demonstrating substantial progress towards generating net positive energy and securing major public and industrial partnerships. But what has changed to bring fusion from research projects to a serious commercial industry?

The commercial fusion market has been catalyzed by recent developments in three areas: a better understanding of the science of fusion, growing global demand for clean energy, and the maturation of enabling technologies.

First, consistent academic progress in understanding plasma physics over multiple decades has now reached the point where fusion technology is becoming ready for commercialization. Research reactors around the world, such as the National Ignition Facility (NIF), the Experimental Advanced Superconducting Tokamak (EAST), and Wendelstein 7-X (W7-X), all produced record-breaking results in recent years such as increasing the energy gain from fusion or sustaining a stable plasma for a longer time.

Secondly, growing global demand for continuous green energy is essential for decarbonizing data centers and industry. Fusion energy avoids intermittency or the need for energy storage, with fewer radiation-related safety risks than its nuclear cousin, fission, which has also seen renewed interest in powering data centers and microgrids.

Finally, a range of specialized materials, components, and software solutions have reached maturity simultaneously to enable innovative fusion power designs. These include high-temperature superconductors, high-energy short-pulse lasers, and surrogate models for plasma simulations. IDTechEx’s report focuses on the value chain for key materials and components and their applications beyond fusion, which startups can pursue to set up secondary revenue streams.

IF YOU AREN’T TEACHING THEM AI YOU AREN’T EDUCATING:

Former Cornell president Martha Pollack ’79 urges universities to embrace artificial intelligence (Sohum Desai, April 25, 2025, The Dartmouth)

Pollack offered a three-part framework for introducing AI to pedagogy: AI literacy, integrating AI into classroom practices and increasing institutional efficiency.

“We need to teach students how to use AI well, but also when not to use it,” she said. “Changing pedagogy is really hard but necessary.”

Pollack gave examples of how faculty across disciplines are experimenting with AI, from law professors prompting chatbots to simulate jury reactions to using large language models for feedback generation. She emphasized that while automation may reduce some faculty workload, the student-professor relationship remains central.

“We’re social animals,” Pollack said. “You don’t go to Red Hawk for the beer — you go for the people. What’s true at the bar is true on campus.”

Pollack also expressed concern over the rising cost of higher education and declining public trust in universities, noting that AI might offer tools to help institutions remain accessible and relevant.

“If the AI education costs 50 cents, and the Dartmouth education costs $50, we risk pricing ourselves out of the market,” she said.

“WHY DO YOU ROB BANKS?”

Patients Kept Nearly Dying at a Texas Hospital. No One Suspected an Inside Job.: How dangerous doctors keep slipping through the system—and how you can protect yourself. (Brent Crane, Nov 22, 2024, Men’s Health)

A disturbing reality was beginning to take shape: Someone at the North Dallas Surgicare center was tampering with those bags.

CLINICIDE REFERS TO doctors who intentionally cause a patient’s death during treatment. It was coined in 2007 by Robert M. Kaplan, a forensic psychiatrist in Sydney, Australia. Though the term is relatively new, the phenomenon is old. One of the first documented cases was that of William Palmer, who poisoned several patients in mid-19th-century England.

Other grim notables include Harold Shipman, a British general practitioner who is thought to have murdered as many as 450 patients in the late 20th century, and Michael Swango, M.D., an American who killed 60 patients in several U. S. states, Zambia, and Zimbabwe between 1983 and 1996.

Nurses have also been prolific killers. In fact, one 2006 study of serial murder by health-care professionals, published in the Journal of Forensic Sciences, found that nurses accounted for 86 percent of the prosecutions of these cases.

The personality types and profiles of perpetrators are myriad, but these people all do harm under the cover of care. The authors of a 2020 paper in the British Medical Journal were blunt: “Arguably, medicine has thrown up more serial killers than all the other professions put together.”


Varied as the psychological motivations behind clinicide may be, “the critical issue is the power doctors hold over life and death,” says Kaplan. Psychopaths, like Shipman and Swango, use the thrill of killing to overcome their inner emotional numbing, and there is also “a gray zone for those with massive hubris who will not accept criticism of their work and see themselves above the issues affecting their patients,” he adds. All of this raises the question: How can we, as patients, trust that our doctor is not one of the bad ones?

In America, there are systems that are supposed to weed out the rotten apples. In 1986, Ronald Reagan signed into law the Health Care Quality Improvement Act. This enabled the formation of the National Practitioners Data Bank (NPDB), a federal database of physician disciplinary, malpractice, judgment, and conviction reports. It was intended to prevent dangerous doctors from jumping from state to state and to provide legal protection for those reporting negligent colleagues.

How is it, then, that nearly four decades later, the problem of lethal health-care professionals persists? That they can rampage through reputable facilities like the Baylor Scott & White North Dallas Surgicare center? One reason is that the average health-care professional is simply not on the lookout for malicious colleagues. “Medicine is messy, and you don’t always get the results you hope for or your patient hopes for,” says Kaplan. “So there’s a great degree of tolerance for adverse events. That takes you a long way before somebody starts thinking, Damn, is he deliberately killing these people?”

The Jessica Simulation: Love and loss in the age of A.I. (Jason Fagone, July 23, 2021 , SF Chronicle)

A lanky 42-year-old with a cheerful attitude and a mischievous streak, Rohrer worked for himself, designing independent video games. He had long championed the idea that games can be art, inspiring complex emotions; his creations had been known to make players weep. And after months of experiments with GPT-2 and GPT-3, he had tapped into a new vein of possibility, figuring out how to make the A.I. systems do something they weren’t designed to do: conduct chat-like conversations with humans.

Last summer, using a borrowed beta-testing credential, Rohrer devised a “chatbot” interface that was driven by GPT-3. He made it available to the public through his website. He called the service Project December. Now, for the first time, anyone could have a naturalistic text chat with an A.I. directed by GPT-3, typing back and forth with it on Rohrer’s site.

Users could select from a range of built-in chatbots, each with a distinct style of texting, or they could design their own bots, giving them whatever personality they chose.

Joshua had waded into Project December by degrees, starting with the built-in chatbots. He engaged with “William,” a bot that tried to impersonate Shakespeare, and “Samantha,” a friendly female companion modeled after the A.I. assistant in the movie “Her.” Joshua found both disappointing; William rambled about a woman with “fiery hair” that was “red as a fire,” and Samantha was too clingy.

But as soon as he built his first custom bot — a simulation of Star Trek’s Spock, whom he considered a hero — a light clicked on: By feeding a few Spock quotes from an old TV episode into the site, Joshua summoned a bot that sounded exactly like Spock, yet spoke in original phrases that weren’t found in any script.

As Joshua continued to experiment, he realized there was no rule preventing him from simulating real people. What would happen, he wondered, if he tried to create a chatbot version of his dead fiancee?

PITY THE POOR PETROPHILES…:

No more fossil “gasplaining” – going electric is past the tipping point and guaranteed to slash cost of living (Sophie Vorrath, Mar 31, 2025, Renew Economy)

The electrification of Australian homes and vehicles is no longer trade-off between climate action and cost, but a guaranteed way to drive down the cost of living – and a economic policy imperative.

A new report from Rewiring Australia says Australia has passed the “electrification tipping point,” where replacing gas appliances and petrol cars with electric alternatives works out cheaper over a 15-year period, even accounting for any higher up-front costs.

This means, for example, that while an electric heat pump hot water system might cost around $4,000 compared to $1,900 for a gas hot water system, a gas system would spend up to $8,000 on fuel over 15 years, compared to $3,900 on grid electricity for the heat pump, or just $1,000 with rooftop solar. […]

Electric driving, too, is now the lowest cost way to drive including upfront costs, according to Rewiring Australia, offering savings of $1,500 per year in driving costs in 2025, or $2,500 with solar.

Over a 15-year period, electric vehicle drivers could expect a saving of $17,000 with upfront costs included, compared to a similar petrol car, or $35,000 when charging with solar.

I’M OLD ENOUGH…:

US students to 3D print hypersonic vehicles with Mach 5 speed for military might (Prabhat Ranjan Mishra, 3/26/25, Interesting Engineering)

The U.S. Army has approved a fresh $3.1 million funding to make hypersonic vehicles faster and more affordable.

A team at the University of Arizona College of Engineering is exploring the use of multiple metallic alloys and additive manufacturing to enable fabrication of Mach-X – pronounced mock-ex – aerospace technologies as part of a federal governmental push.

The team, led by Sammy Tin, revealed that the Mach-X vehicles will travel at speeds faster than Mach 5, which is five times the speed of sound and the hypersonic threshold.

…to remember when we’d only ever be able to print shower curtain rings…

THE MODERN QUILL:

What’s in a Name: Signatures, autopen, and the question of verifiable identity (David E. Brown, Winter 2001/2, CABINET)

An Autopen looks like a cross between a school desk and a pantograph—an arm jutting out of a 1960s-looking enclosure grips a felt-tip pen. Inside the machine is a model of a signature; the penned arm extends out onto the desk and accurately re-creates the signature “matrix” inside, hundreds or thousands of times a day. Early users were presidents and CEOs, who could have spent weeks signing their names, barely making a dent in the demands of the important identity. (A more recent application is direct-mail marketing, which benefits from a “personal” touch.)


The Autopen was a lifesaver for important men. But the Autopen undid some of the progress that had been made in identification. Your signature, with its practiced flourish, is as close to you that writing can get. “I am that I am,” your signature wants to say. And that closeness-to-you is what convinces governments and banks and landlords that you are who you claim to be. But how can that certainty exist along with a machine that can sign and sign and sign, with no care as to who has told the machine to sign? (It can’t, as evidenced by a series of unauthorized, autopenned Donald Rumsfeld signatures that appeared on official documents in early 2001.2)

To say nothing of value. After the Autopen was adopted by US presidents (LBJ was a big user, as was Nixon and everyone since) it found new markets among celebrities. It really is hard to sign your name for hours and hours, but maybe not so hard as disappointing one’s fans. So by the late 1960s many famous people had their own Autopens churning out signatures for the people. And while Autopen signatures from presidents and business leaders had been accepted at more or less face value, they did not have to deal with the invisible hand of the collectibles market. An Autopenned document may be good enough for the Department of Defense, but don’t try to convince a collector that a machine carries the emotional—and thus, in the irrational economics of nostalgia, financial—weight of a real autograph.

A recent eBay search turned up just two Autopenned items among the 60,000-plus autographed 8x10s, books, and other baubles up for sale. And of that multitude of signatures up for bid, hundreds of their sellers went out of their way to point out that they weren’t Autopenned. If we accept the opinion of the collectibles market—and as odd as that market is, there seems to be no reason not to—then eBay has become the ultimate measure of desire, value, and authenticity. And that measure says that more than a century of effort to create a mechanical stand-in for the human hand, for the written personality, has come to naught.

PATIENT, HEAL THYSELF:

“Honest” placebos: Sugar pills can work even when you know they’re fake (Rich Haridy, February 22, 2025, New Atlas)

A fascinating study published in 2018 found patients suffering from cancer-related fatigue displayed significant improvement in their symptoms after being given an inert placebo. All the subjects were told at the beginning of the trial that the pills they were given contained no active pharmacological ingredients, yet a notable placebo effect was still detected. The research was just one piece of evidence in a compelling body of work suggesting “honest” placebos could play a role in certain kinds of clinical treatments.

It’s all in your head…

HARSHING THE SINOPHOBE MELLOW:

What sparked the COVID pandemic? Mounting evidence points to raccoon dogs (Smriti Mallapaty, 2/21/25, Nature)


One of the reasons raccoon dogs were suggested as a prime candidate early on is because they were probably involved in passing another, related, virus to people. In 2003, researchers isolated close matches of the virus that causes severe acute respiratory syndrome (SARS) in several civets and a raccoon dog at a live-animal market in Guangdong, China.

This finding prompted researchers in Germany to investigate these animals’ susceptibility to SARS-CoV-21.

They found that raccoon dogs can be infected by SARS-CoV-2, and — despite not getting that sick themselves — can pass on the infection to other animals.

Studies by Holmes and his colleagues have also shown that farmed and wild raccoon dogs in China are often infected with many viruses that can jump between species. “Raccoon dogs are very common viral hosts,” says Holmes.


Many of the first cases of COVID-19 involved the Huanan market, suggesting it was the location of the viral spillover. SARS-CoV-2 sequences from the first infected people, in late December 2019 and early January 2020, along with geolocation and epidemiological data, support this2.

During the outbreak, the market was shut down by the authorities, but researchers know that raccoon dogs were being sold there, for their fur and as food. In June 2021, a study described the results of monthly surveys of live wild animals sold across four markets in Wuhan between May 2017 and November 2019, including seven stalls at Huanan3. Every month, an average of 38 raccoon dogs were sold at these markets. The most-sold species was the Amur hedgehog (Erinaceus amurensis) at an average 332 individuals a month. Masked palm civet (Paguma larvata), hog badgers (Arctonyx albogularis), Chinese bamboo rats (Rhizomys sinensis), and Malayan porcupines (Hystrix brachyura) were also regularly sold.

December 2019 sales records from the Huanan market also list trading of live animals or products from bamboo rats, porcupines and hedgehogs, among others.

Further evidence to support the raccoon-dog theory came in 2023. Chinese researchers published genomic data of swabs taken at the Huanan market in January 2020, after it was shut down, including of stalls, rubbish bins and sewage4. Studies found mitochondrial DNA of raccoon dogs in several swabs, including those that also tested positive for SARS-CoV-2. Raccoon dogs and hoary bamboo rats (Rhizomys pruinosus) were the most common mammalian wildlife species detected in the mitochondrial DNA; material from civets and hog badgers was also found but not in many samples5. The findings don’t prove that the animals were infected with SARS-CoV-2, but had they been infected, this is the type of evidence you would expect to find, says Andersen.

…and Lee Harvey Oswald shot JFK.

YOUR NEXT PLANE WILL BE A VOLT:

Electric air taxis could soon replace short-haul flights — here’s how they’re moving closer to reality: One study recently estimated that urban congestion costs the U.S. nearly $120 billion per year in lost time and fuel (Rachel BeyerFebruary 20, 2025, The Cool Down)

Getting around cities is already tough. Roads are packed, and short-haul flights that are typically under 500 miles produce some of the most pollution per passenger mile. The VX4 aims to change that by replacing gas-powered flights and car commutes with zero-emission air travel. Rather than wasting time in traffic, commuters could fly across the city in just minutes. If these aircraft become widely used, they could do more than save time. They might also help reduce pollution in crowded urban areas.

A report from McKinsey & Company predicts that urban air travel could grow quickly.

That was easy.
