Legal challenges over the powerful wartime law have gone all the way to the Supreme Court.

The event is stirring memories of an exhibition in 1970, when the postwar Japanese economy was taking off and “you could have dreams about the future.”

Thierno Agne left behind studying law to grow strawberries, a shocking move in Senegal, where farming is considered work for the old, poor and uneducated. His success is making the profession “sexy.”

"Seismologist Deborah Kilb was wading through California earthquake records from the past four decades when she noticed something odd," reports CNN, "a series of deep earthquakes that had occurred under the Sierra Nevada at a depth where Earth's crust would typically be too hot and high pressure for seismic activity..." Kilb flagged the data to Vera Schulte-Pelkum, a research scientist at the Cooperative Institute for Research in Environmental Sciences and an associate research professor of geological sciences at the University of Colorado Boulder... Using the newfound data, the researchers imaged the Sierra Nevada through a technique known as receiver function analysis, which uses seismic waves to map Earth's internal structure. The scientists found that in the central region of the mountain range, Earth's crust is currently peeling away, a process scientifically known as lithospheric foundering. Kilb and Schulte-Pelkum reported the findings in December in the journal Geophysical Research Letters. The hypothesis lined up with previous speculation that the area had undergone lithospheric foundering, which happens when Earth's outermost layer sinks into the lower layer of the mantle. Now, the study authors believe that the process is ongoing and is currently progressing to the north of the mountain range, according to the study... What's happening under the Sierra Nevada could offer rare insight into how the continents formed, Schulte-Pelkum said. The finding could also help scientists identify more areas where this process is happening as well as provide a better understanding of earthquakes and how our planet operates, she added... Evidence for this process has been hard to come by. It is not visible from above ground, and it's an extremely slow process. Scientists theorize that the south Sierra finished the process of lithospheric foundering about 4 million to 3 million years ago, according to the study. It appears that these natural events happen occasionally around the world, Schulte-Pelkum said. "Geologically speaking, this is a pretty quick process with long periods of stability in between. ... This (lithosphere foundering) probably started happening a long time ago when we started building continents, and (the continents) have gotten bigger over time. So it's just sort of this punctuated, localized thing," she added... Further study within this area could also help scientists better understand how the Earth evolves on long timescales. If the lithospheric foundering continues underneath the mountain range, one can speculate that the land will continue to stretch vertically, changing the way the landscape looks now [said Mitchell McMillan, a research geologist and postdoctoral fellow at Georgia Tech, who was not involved with the study]. But that could take anywhere from several hundred thousand to a few million years, he added.

CNN looks at "one field that's really benefitting" from the use of AI: "the discovery of new medicines". The founder/CEO of London-based LabGenius says their automated robotic system can assemble "thousands of different DNA constructs, each of which encodes a completely unique therapeutic molecule that we'll then test in the lab. This is something that historically would've had to have been done by hand." In short, CNN says, their system lets them "design and conduct experiments, and learn from them in a circular process that creates molecular antibodies at a rate far faster than a human researcher." While many cancer treatments have debilitating side effects, CNN notes that LabGenius "reengineers therapeutic molecules so they can selectively target just the diseased cells." But more importantly, their founder says they've now discovered "completely novel molecules with over 400x improvement in [cell] killing selectivity." A senior lecturer at Imperial College London tells CNN that LabGenius seems to have created an efficient process with seamless connections, identifying a series of antibodies that look like they can target cancer cells very selectively "that's as good as any results I've ever seen for this." (Although the final proof will be what happens when they test them on patients..) "And that's the next step for Labgenius," says CNN. "They aim to have their first therapeutics entering clinics in 2027." Finally, CNN asks, if it succeeds is their potential beyond cancer treatment? "If you take one step further," says the company's CEO/founder, "you could think about knocking out senescent cells or aging cells as a way to treat the underlying cause of aging."

Billions of years ago Mars "had a warm, habitable climate with liquid water in lakes and flowing rivers," writes Ars Technica. But "In order for Mars to be warm enough to host liquid water, there must have been a lot of carbon dioxide in the atmosphere," says Benjamin Tutolo, a researcher at the University of Calgary. "The question we've been asking for at least 30 years was where the record of all this carbon is." Tutolo led a new study of rock samples collected by the Curiosity rover that might have answered this question... Curiosity rover was called Mars Science Laboratory for a reason. It went to the red planet fitted with a suite of instruments, some of which even the newer Perseverance was lacking. These enabled it to analyze the collected Martian rocks on the spot and beam the results back to Earth. "To get the most bang for the buck, NASA decided to send it to the place on Mars called the Gale Crater, because it was the tallest stack of sediments on the planet," Tutolo says. The central peak of Gale Crater was about 5 kilometers tall, created by the ancient meteorite impact... The idea then was to climb up Mount Sharp and collect samples from later and later geological periods at increasing elevations, tracing the history of habitability and the great drying up of Mars. On the way, the carbon missed by the satellites was finally found... It turned out the samples contained roughly between 5 and 10 percent of siderite... The siderite found in the samples was also pure, which Tutolo thinks indicates it has formed through an evaporation process akin to what we see in evaporated lakes on Earth. This, in turn, was the first evidence we've found of the ancient Martian carbon cycle. "Now we have evidence that confirms the models," Tutolo claims. The carbon from the atmosphere was being sequestered in the rocks on Mars just as it is on Earth. The problem was, unlike on Earth, it couldn't get out of these rocks... A large portion of carbon that got trapped in Martian rocks stayed in those rocks forever, thinning out the atmosphere. "While it's likely the red planet had its own carbon cycle, it was an imperfect one that eventually turned it into the lifeless desert it is today," the article points out. But the study still doesn't entirely explain what warmed the atmosphere of Mars — or why Martian habitability "was seemingly intermittent and fluctuating".

For combining machine learning with astronomy, high school senior Matteo Paz won $250,000 in the Regeneron Science Talent Search, reports Smithsonian magazine: The young scientist's tool processed 200 billion data entries from NASA's now-retired Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) telescope. His model revealed 1.5 million previously unknown potential celestial bodies.... [H]e worked on an A.I. model that sorted through the raw data in search of tiny changes in infrared radiation, which could indicate the presence of variable objects. Working with a mentor at the Planet Finder Academy at Caltech, Paz eventually flagged 1.5 million potential new objects, accoridng to the article, including supernovas and black holes. And that mentor says other Caltech researchers are using Paz's catalog of potential variable objects to study binary star systems.

"Members of the CA/Browser Forum have voted to slash cert lifespans from the current one year to 47 days," reports Computerworld, "placing an added burden on enterprise IT staff who must ensure they are updated." In a move that will likely force IT to much more aggressively use web certificate automation services, the Certification Authority Browser Forum (CA/Browser Forum), a gathering of certificate issuers and suppliers of applications that use certificates, voted [last week] to radically slash the lifespan of the certificates that verify the ownership of sites. The approved changes, which passed overwhelmingly, will be phased in gradually through March 2029, when the certs will only last 47 days. This controversial change has been debated extensively for more than a year. The group's argument is that this will improve web security in various ways, but some have argued that the group's members have a strong alternative incentive, as they will be the ones earning more money due to this acceleration... Although the group voted overwhelmingly to approve the change, with zero "No" votes, not every member agreed with the decision; five members abstained... In roughly one year, on March 15, 2026, the "maximum TLS certificate lifespan shrinks to 200 days. This accommodates a six-month renewal cadence. The DCV reuse period reduces to 200 days," according to the passed ballot. The next year, on March 15, 2027, the "maximum TLS certificate lifespan shrinks to 100 days. This accommodates a three-month renewal cadence. The DCV reuse period reduces to 100 days." And on March 15, 2029, "maximum TLS certificate lifespan shrinks to 47 days. This accommodates a one-month renewal cadence. The DCV reuse period reduces to 10 days." The changes "were primarily pushed by Apple," according to the article, partly to allow more effective reactions to possible changes in cryptography. And Apple also wrote that the shift "reduces the risk of improper validation, the scope of improper validation perpetuation, and the opportunities for misissued certificates to negatively impact the ecosystem and its relying parties."

An anonymous reader shared this report from CNBC: Neurotech startup Precision Neuroscience on Thursday announced that a core component of its brain implant system has been approved by the U.S. Food and Drug Administration, a major win for the four-year-old company... The company's brain-computer interface will initially be used to help patients with severe paralysis restore functions such as speech and movement, according to its website. Only part of Precision's system was approved by the FDA on Thursday, but it marks the first full regulatory clearance granted to a company developing a wireless BCI, Precision said in a release. Other prominent startups in the space include Elon Musk's Neuralink, and Synchron, which is backed by Amazon founder Jeff Bezos and Microsoft co-founder Bill Gates.... The piece of Precision's system that the FDA approved is called the Layer 7 Cortical Interface. The microelectrode array is thinner than a human hair and resembles a piece of yellow scotch tape. Each array is made up of 1,024 electrodes that can record, monitor and stimulate electrical activity on the brain's surface. When it is placed on the brain, Precision says it can conform to the surface without damaging any tissue. The FDA authorized Layer 7 to be implanted in patients for up to 30 days, and Precision will be able to market the technology for use in clinical settings. This means surgeons will be able to use the array during procedures to map brain signals, for instance. It is not Precision's end goal for the technology, but it will help the company generate revenue in the near term. Precision's co-founder and chief science officer also helped co-found Musk's Neuralink in 2017 before departing the following year, according to the article. He nows says this regulatory clearance "will exponentially increase our access to diverse, high-quality data, which will help us to build BCI systems that work more effectively."

In NoSQL database news, Arch Linux "is the latest Linux distribution replacing its Redis packages with the Valkey fork," reports Phoronix. Valkey is backed by the Linux Foundation, Google, Amazon Web Services, and Oracle, which the article points out is due to Redis's decision last year to shift the upstream Redis license from a BSD 3-clause to RSALv2 and SSPLv1. Valkey is replacing Redis in the Arch Linux extra repository and after a two week period the Redis package will be moved out to AUR and receive no further updates. Users are encouraged to migrate to Valkey as soon as possible.

"Russia is automating the spread of false information to fool AI chatbots," reports the Washington Post. (When researchers checked 10 chatbots, a third of the responses repeated false pro-Russia messaging.) The Post argues that this tactic offers "a playbook to other bad actors on how to game AI to push content meant to inflame, influence and obfuscate instead of inform," and calls it "a fundamental weakness of the AI industry." Chatbot answers depend on the data fed into them. A guiding principle is that the more the chatbots read, the more informed their answers will be, which is why the industry is ravenous for content. But mass quantities of well-aimed chaff can skew the answers on specific topics. For Russia, that is the war in Ukraine. But for a politician, it could be an opponent; for a commercial firm, it could be a competitor. "Most chatbots struggle with disinformation," said Giada Pistilli, principal ethicist at open-source AI platform Hugging Face. "They have basic safeguards against harmful content but can't reliably spot sophisticated propaganda, [and] the problem gets worse with search-augmented systems that prioritize recent information." Early commercial attempts to manipulate chat results also are gathering steam, with some of the same digital marketers who once offered search engine optimization — or SEO — for higher Google rankings now trying to pump up mentions by AI chatbots through "generative engine optimization" — or GEO. Our current situation "plays into the hands of those with the most means and the most to gain: for now, experts say, that is national governments with expertise in spreading propaganda." Russia and, to a lesser extent, China have been exploiting that advantage by flooding the zone with fables. But anyone could do the same, burning up far fewer resources than previous troll farm operations... In a twist that befuddled researchers for a year, almost no human beings visit the sites, which are hard to browse or search. Instead, their content is aimed at crawlers, the software programs that scour the web and bring back content for search engines and large language models. While those AI ventures are trained on a variety of datasets, an increasing number are offering chatbots that search the current web. Those are more likely to pick up something false if it is recent, and even more so if hundreds of pages on the web are saying much the same thing... The gambit is even more effective because the Russian operation managed to get links to the Pravda network stories edited into Wikipedia pages and public Facebook group postings, probably with the help of human contractors. Many AI companies give special weight to Facebook and especially Wikipedia as accurate sources. (Wikipedia said this month that its bandwidth costs have soared 50 percent in just over a year, mostly because of AI crawlers....) Last month, other researchers set out to see whether the gambit was working. Finnish company Check First scoured Wikipedia and turned up nearly 2,000 hyperlinks on pages in 44 languages that pointed to 162 Pravda websites. It also found that some false information promoted by Pravda showed up in chatbot answers. "They do even better in such places as China," the article points out, "where traditional media is more tightly controlled and there are fewer sources for the bots." (The nonprofit American Sunlight Project calls the process "LLM grooming".) The article quotes a top Kremlin propagandist as bragging in January that "we can actually change worldwide AI."
