How hot salt could transform nuclear power

For more than a month in total, 12 metric tons of molten salt coursed through pipes at Kairos Power in Albuquerque, New Mexico.

The company is developing a new type of nuclear reactor that will be cooled using this salt mixture, and its first large-scale test cooling system just completed 1,000 hours of operation in early January. This is the second major milestone for Kairos in recent weeks. In December, the US Nuclear Regulatory Commission granted a construction permit for the company’s first nuclear test reactor.

Nuclear power plants can provide a steady source of carbon-free energy, but projects to build them have been plagued by delays and skyrocketing budgets. Kairos hopes to change nuclear powers’ fortunes with a new version of the technology that could cut costs and construction times. Read the full story.

A new AI-based risk prediction system could help catch deadly pancreatic cancer cases earlier

What’s happened: A new AI system could help detect the most common form of pancreatic cancer, new research has found. The system outperformed current diagnostic standards and could be used in a clinical setting to identify patients who would benefit from early screening or testing, helping catch the disease earlier and save lives.

How they did it: The researchers fed two AI models anonymized data from 6 million electronic health records, 35,387 of which were pancreatic cancer cases, from 55 health-care organizations in the US. The neural network identified 35% of patients who had the disease as high risk 6 to 18 months before they were diagnosed, compared to current screening guidelines of 10%. Read the full story.

Is robotics about to have its own ChatGPT moment?

henry evans P0005882 scaled

Silent. Rigid. Clumsy.

Henry and Jane Evans are used to awkward houseguests. For more than a decade, the couple, who live in Los Altos Hills, California, have hosted a slew of robots in their home.

In 2002, at age 40, Henry had a massive stroke, which left him with quadriplegia and an inability to speak. Since then, he’s learned how to communicate by moving his eyes over a letter board, but he is highly reliant on caregivers and his wife, Jane.

Henry got a glimmer of a different kind of life when he saw Charlie Kemp on CNN in 2010. Kemp, a robotics professor at Georgia Tech, was on TV talking about PR2, a robot developed by the company Willow Garage. PR2 was a massive two-armed machine on wheels that looked like a crude metal butler. Kemp was demonstrating how the robot worked, and talking about his research on how health-care robots could help people. He showed how the PR2 robot could hand some medicine to the television host.

“All of a sudden, Henry turns to me and says, ‘Why can’t that robot be an extension of my body?’ And I said, ‘Why not?’” Jane says.

There was a solid reason why not. While engineers have made great progress in getting robots to work in tightly controlled environments like labs and factories, the home has proved difficult to design for. Out in the real, messy world, furniture and floor plans differ wildly; children and pets can jump in a robot’s way; and clothes that need folding come in different shapes, colors, and sizes. Managing such unpredictable settings and varied conditions has been beyond the capabilities of even the most advanced robot prototypes.

That seems to finally be changing, in large part thanks to artificial intelligence. For decades, roboticists have more or less focused on controlling robots’ “bodies”—their arms, legs, levers, wheels, and the like—via purpose-­driven software. But a new generation of scientists and inventors believes that the previously missing ingredient of AI can give robots the ability to learn new skills and adapt to new environments faster than ever before. This new approach, just maybe, can finally bring robots out of the factory and into our homes.

Progress won’t happen overnight, though, as the Evanses know far too well from their many years of using various robot prototypes.

PR2 was the first robot they brought in, and it opened entirely new skills for Henry. It would hold a beard shaver and Henry would move his face against it, allowing him to shave and scratch an itch by himself for the first time in a decade. But at 450 pounds (200 kilograms) or so and $400,000, the robot was difficult to have around. “It could easily take out a wall in your house,” Jane says. “I wasn’t a big fan.”

More recently, the Evanses have been testing out a smaller robot called Stretch, which Kemp developed through his startup Hello Robot. The first iteration launched during the pandemic with a much more reasonable price tag of around $18,000.

Stretch weighs about 50 pounds. It has a small mobile base, a stick with a camera dangling off it, and an adjustable arm featuring a gripper with suction cups at the ends. It can be controlled with a console controller. Henry controls Stretch using a laptop, with a tool that that tracks his head movements to move a cursor around. He is able to move his thumb and index finger enough to click a computer mouse. Last summer, Stretch was with the couple for more than a month, and Henry says it gave him a whole new level of autonomy. “It was practical, and I could see using it every day,” he says.

Using his laptop, he could get the robot to brush his hair and have it hold fruit kebabs for him to snack on. It also opened up Henry’s relationship with his granddaughter Teddie. Before, they barely interacted. “She didn’t hug him at all goodbye. Nothing like

A brief, weird history of brainwashing

Liang Qichao portrait jpg

On an early spring day in 1959, Edward Hunter testified before a US Senate subcommittee investigating “the effect of Red China Communes on the United States.” It was the kind of opportunity he relished. A war correspondent who had spent considerable time in Asia, Hunter had achieved brief media stardom in 1951 after his book Brain-Washing in Red China introduced a new concept to the American public: a supposedly scientific system for changing people’s minds, even making them love things they once hated.

But Hunter wasn’t just a reporter, objectively chronicling conditions in China. As he told the assembled senators, he was also an anticommunist activist who served as a propagandist for the OSS, or Office of Strategic Services—something that was considered normal and patriotic at the time. His reporting blurred the line between fact and political mythology.

Chinese reformists like Liang Qichao used the term xinao—a play on an older word, xixin, or “washing the heart”—in an attempt to bring ideas from Western science into Chinese philosophyWIKIMEDIA COMMONS

When a senator asked about Hunter’s work for the OSS, the operative boasted that he was the first to “discover the technique of mind-attack” in mainland China, the first to use the word “brainwashing” in writing in any language, and “the first, except for the Chinese, to use the word in speech in any language.”

None of this was true. Other operatives associated with the OSS had used the word in reports before Hunter published articles about it. More important, as the University of Hong Kong legal scholar Ryan Mitchell has pointed out, the Chinese word Hunter used at the hearing—xinao (), translated as “wash brain”—has a long history going back to scientifically minded Chinese philosophers of the late 19th century, who used it to mean something more akin to enlightenment.

Yet Hunter’s sensational tales still became an important part of the disinformation and pseudoscience that fueled a “mind-control race” during the Cold War, much like the space race. Inspired by new studies on brain function, the US military and intelligence communities prepared themselves for a psychic war with the Soviet Union and China by spending millions of dollars on research into manipulating the human brain. But while the science never exactly panned out, residual beliefs fostered by this bizarre conflict continue to play a role in ideological and scientific debates to this day.

Coercive persuasion and pseudoscience

Ironically, “brainwashing” was not a widely used term among communists in China. The word xinao, Mitchell told me in an email, is actually a play on an older word, xixin, or washing the heart, which alludes to a Confucian and Buddhist ideal of self-awareness. In the late 1800s, Chinese reformists such as Liang Qichao began using xinao—replacing the character for “heart” with “brain”—in part because they were trying to modernize Chinese philosophy. “They were eager to receive and internalize as much as they could of Western science in general, and discourse about the brain as the seat of consciousness was just one aspect of that set of imported ideas,” Mitchell said.

For Liang and his circle, brainwashing wasn’t some kind of mind-wiping process. “It was a sort of notion of epistemic virtue,” Mitchell said, “or a personal duty to make oneself modern in order to behave properly in the modern world.”

Meanwhile, scientists outside China were investigating “brainwashing” in the sense we usually think of, with experiments into mind clearing and reprogramming. Some of the earliest research into the possibility began in the 1890s, when Ivan Pavlov, the Russian physiologist who had famously conditioned dogs to drool at the sound of a bell, worked on Soviet-funded projects to investigate how trauma could change animal behavior. He found that even the most well-conditioned dogs would forget their training after intensely stressful experiences such as nearly drowning, especially when those were combined with sleep deprivation and isolation. It seemed that Pavlov had hit upon a quick way to wipe animals’ memories. Scientists on both sides of the Iron Curtain subsequently wondered whether it might work on humans. And once memories were wiped, they wondered, could something else be installed their place?
