Chances its Arm that maker community is looking for a fresh SBC:

Asus has unveiled a RISC-V model in its range of Tinker Board single board computer (SBC) systems, which up until now have all been Arm-based. However, it seems users should not expect too much in the way of performance from this first device.

The Tinker Board has been around since 2017 as Asus' answer to the Raspberry Pi, even keeping the same form factor and GPIO pinout in some models. Like the Pi, they have been based on various Arm-based system-on-chip (SoC) hardware.

Announced this week, the Tinker V is powered by a 64-bit RISC-V chip and aimed at embedded and IoT applications, but like other Tinker Boards and the Raspberry PI, is likely to find its way into the hands of makers and enthusiasts as well.

According to Asus, Tinker V "provides impressive power, comprehensive functionality and rich connectivity, making it the perfect choice for a diverse range of industrial IoT applications".

However, it is based on a 1GHz Renesas RZ/Five chip, which has just a single CPU core, the AX45MP designed by Andes Technology, whereas most rival products sport multiple processor cores.

Tinker V also features 1GB of DDR4 memory and an optional 16GB eMMC SSD, plus a range of I/O including GPIO ports on a 20 pin header, micro-USB, dual gigabit Ethernet ports, a pair of CAN bus interfaces and two RS232 ports, all on a Pico-ITX board.

As befits its intended purpose as an IoT platform, the system supports Yocto Linux as well as the Debian distribution, Asus said. It also lacks a display output, unlike many other Tinker Board models. Full specifications for Tinker V can be found here.

Asus said it is offering at least five years of support for Tinker V, plus dedicated on-site technical support is also available to shorten customer development cycles and accelerate application deployment.

The move shows that the RISC-V open-source instruction set architecture continues to garner support. The last RISC-V Summit in San Jose saw the launch of a family of datacenter-class processors based on the architecture from Ventana Micro Systems, while XMOS unveiled new high-performance microcontrollers using RISC-V.

According to Asus, Tinker V samples will be available in Q2 of this year, but it did not disclose a date for full availability or pricing.

The COVID-19 pandemic contributed to the higher rate in 2020 and 2021:

An increasing number of U.S. women are dying during pregnancy or soon after giving birth, according to the latest data on the maternal mortality rate.

In 2021, there were 32.9 deaths per 100,000 live births, compared with 23.8 per 100,000 in 2020 and 20.1 in 2019, the National Center for Health Statistics reports March 16. The U.S. rate greatly exceeds those of other high-income countries. The total number of U.S. maternal deaths rose from 861 in 2020 to 1,205 in 2021.

There remains a wide disparity in the maternal mortality rate for Black women, at 69.9 deaths per 100,000 live births, compared with white women, at 26.6 per 100,000. Many social determinants of health underlie this gap, including differences in the quality of care that Black women receive before, during and after pregnancy.

The NCHS report doesn't discuss the reasons behind the increase for 2021. But COVID-19 contributed to a quarter of maternal deaths in 2020 and 2021, the U.S. Government Accountability Office reported in October. The pandemic also contributed to the mortality disparity between Black and white women, the GAO found, worsening existing structural inequities that lead to such issues as barriers to getting health care (SN: 4/10/20).

The U.S. maternal mortality rate has risen overall since 2018. The highest rate is among non-Hispanic Black women compared with Hispanic women and non-Hispanic white women.

The maternal deaths captured by the NCHS report are those that occur during pregnancy or within 42 days of the end of the pregnancy, "from any cause related to or aggravated by the pregnancy or its management." These causes include hemorrhaging, infections and high blood pressure disorders such as eclampsia.

The report excludes deaths after 42 days and up to the first year after birth. But 30 percent of pregnancy-related deaths occur during this period, the U.S. Centers for Disease Control and Prevention reported in September, from an analysis of the years 2017 to 2019.

For genetics, use scientifically relevant descriptions, not outdated social ideas:

With the advent of genomic studies, it's become ever more clear that humanity's genetic history is one of churn. Populations migrated, intermingled, and fragmented wherever they went, leaving us with a tangled genetic legacy that we often struggle to understand. The environment—in the form of disease, diet, and technology—also played a critical role in shaping populations.

But this understanding is frequently at odds with the popular understanding, which often views genetics as a determinative factor and, far too often, interprets genetics in terms of race. Worse still, even though race cannot be defined or quantified scientifically, popular thinking creeps back into scientific thought, shaping the sort of research we do and how we interpret the results.

Those are some of the conclusions of a new report produced by the National Academies of Science. Done at the request of the National Institutes of Health (NIH), the report calls for scientists and the agencies that fund them to stop thinking of genetics in terms of race, and instead to focus on things that can be determined scientifically.

The report is long overdue. Genetics data has revealed that the popular understanding of race, developed during a time when white supremacy was widely accepted, simply doesn't make any sense. In the popular view, for instance, "Black" represents a single, homogenous group. But genomic data makes clear that populations in Sub-Saharan Africa are the most genetically diverse on Earth.

And, like everywhere else, populations in this region haven't stayed static. While some groups remained isolated from each other, the vast Bantu expansion touched most of the continent. Along the coast of East Africa, the history of interchange with Mideastern traders can be detected in many groups. There's also a tendency to treat African Americans as being equivalent to African, when the former population carries the legacy of genetic mixing with European populations—often not by choice.

Similar things are true for every population we have looked at, no matter where on the globe they reside. Treating any of these populations as a monolithic, uniform group—as a race, in other words—makes no scientific sense.

Yet in countless ways, scientists have done just that. In some cases, the reasons for this have been well-meaning ones, as with the priority to diversify the populations involved in medical studies. In other cases, scientists have carelessly allowed social views of race to influence research that could otherwise have had a solid empirical foundation. Finally, true believers in racial essentialism have always twisted scientific results to support their views.

The NIH, as the largest funder of biomedical research on the planet, has been forced to navigate our growing understanding of genetics while trying to diversify both the researchers it funds and the participants who volunteer to be part of these studies. NIH thus commissioned the National Academies to generate this report, presumably in the hope it would provide evidence-based guidelines on how to manage the sometimes competing pressures.

The resulting report makes clear why racial thinking needs to go. A summary of the mismatch between race and science offers welcome clarity on the problem:

In humans, race is a socially constructed designation, a misleading and harmful surrogate for population genetic differences, and has a long history of being incorrectly identified as the major genetic reason for phenotypic differences between groups. Rather, human genetic variation is the result of many forces—historical, social, biological—and no single variable fully represents this complexity. The structure of genetic variation results from repeated human population mixing and movements across time, yet the misconception that human beings can be naturally divided into biologically distinguishable races has been extremely resilient and has become embedded in scientific research, medical practice and technologies, and formal education.

The results of racial thinking are problematic in a variety of ways. Historically, we've treated race as conveying some essential properties, and thinking of populations in terms of race tends to evoke that essentialist perspective—even though it's clear that any population has a complicated mixture of genetic, social, and environmental exposures. Essentialist thinking also tends to undermine recognition of the important role played by those environmental and social factors in shaping the population.

The report also notes that science's racial baggage leads to sloppy thinking. Scientists will often write in broad racial terms when they're working with far more specific populations, and they'll mention racial groups even when it's not clear that the information is even relevant to their results. These tendencies have grown increasingly untenable as we've gotten far better at directly measuring the things that race was meant to be a proxy for, such as genetic distance between individuals.

A bruising, failed 16-month FCC nomination has left President Joe Biden with little time to staff up the agency before 2024:

Shortly after coming into office, President Joe Biden moved to restore net neutrality. He signed a sweeping executive order to promote competition, calling on the Federal Communications Commission (FCC) to bring back the Obama-era internet rules rolled back by the Trump administration.

But close to two years later, the FCC remains deadlocked with only four of its five commissioner slots filled — and Biden may be running out of time.

Biden's pick for a new FCC commissioner was Gigi Sohn, a former FCC official and public interest advocate. Sohn would have secured a long-awaited Democratic majority at the agency. After she was nominated in October 2021, however, a well-funded opposition organized a brutal opposition campaign against her. The culture-war campaign called Sohn an "extremist" and a "censor" because of past tweets criticizing Fox News and former President Donald Trump, largely ignoring her decades-long professional record. After more than 16 months and three separate confirmation hearings, Sohn withdrew her nomination earlier this month, citing the "unrelenting, dishonest and cruel attacks" by broadband and cable lobbyists and their friends.

It's unlikely Biden will pick someone as critical of cable companies again — but Republicans could try to thwart even a centrist candidate

Now, the White House has been forced to start over, prolonging a vacancy that continues to obstruct the administration's broadband agenda. The White House hasn't announced a new nominee or when they're hoping to confirm someone, but it's unlikely that Biden would pick someone as critical of cable companies as Sohn. Republicans and "dark money" groups have already proved that they're willing to spend millions to block progressive nominees. With so little time left in Biden's first term, stakeholders may even try to thwart a more moderate nominee, especially if there's an opportunity to continue the stalemate past the 2024 election.

Even if the White House selects a new nominee in the next few weeks, it could take months for them to be vetted and confirmed by the Senate. If the White House drags its feet in finding a replacement, Biden could be without a fifth commissioner when the 2024 election season begins. "The FCC deadlock, now over two years long, will remain so for a long time," Sohn said in a statement announcing her withdrawal last week. "It is a sad day for our country and our democracy when dominant industries, with assistance from unlimited dark money, get to choose their regulators."

Net neutrality, which bans internet service providers from favoring or degrading the quality of specific services, was one of Biden's big-ticket promises. But as it's an issue that mostly splits down party lines, the FCC's stalemate has left his hands tied — putting states in charge of issuing their own patchwork rules.

Other parts of Biden's agenda have suffered the same problem, including ones that are facing looming deadlines.

His 2021 infrastructure package required the agency to craft rules that would ensure all Americans, despite income status, have equal access to the internet. The agency has until November to draft these new digital discrimination rules, but civil rights groups fear it may be impossible to roll out meaningful protections without a third commissioner.

"If advanced, the rule could hold broadband providers liable if their practices result in less internet access for people of color and low income communities, even if companies don't intentionally discriminate," the Leadership Conference on Civil and Human Rights said in a February statement on the rulemaking. "Without a fully functioning FCC, that rule is likely to be much weaker."

"Lack of FCC oversight has enabled collection and sale of cell phone location data that puts vulnerable communities at risk"

Getting To Zettascale Without Needing Multiple Nuclear Power Plants:

There's no resting on your laurels in the HPC world, no time to sit back and bask in a hard-won accomplishment that was years in the making. The ticker tape has only now been swept up in the wake of the long-awaited celebration last year of finally reaching the exascale computing level, with the Frontier supercomputer housed at the Oak Ridge National Labs breaking that barrier.

With that in the rear-view mirror, attention is turning to the next challenge: Zettascale computing, some 1,000 times faster than what Frontier is running. In the heady months after his heralded 2021 return to Intel as CEO, Pat Gelsinger made headlines by saying the giant chip maker was looking at 2027 to reach zettascale.

Lisa Su, the chief executive officer who has led the remarkable turnaround at Intel's chief rival AMD, took the stage at ISSCC 2023 to talk about zettascale computing, laying out a much more conservative – some would say reasonable – timeline.

Looking at supercomputer performance trends over the past two-plus decades and the ongoing innovation in computing – think advanced package technologies, CPUs and GPUs, chiplet architectures, the pace of AI adoption, among others – Su calculated that the industry could reach the zettabyte scale within the next 10 years or so.

"We just recently passed a very significant milestone last year, which was the first exascale supercomputer," she said during her talk, noting that Frontier – built using HPE systems running on AMD chips – is "using a combination of CPUs and GPUs. Lots of technology in there. We were able to achieve an exascale of supercomputing, both from a performance standpoint and, more importantly, from an efficiency standpoint. Now we draw the line, assuming that [we can] keep that pace of innovation going. ... That's a challenge for all of us to think through. How might we achieve that?"

Supercomputing efficiency is doubling every 2.2 years, but that still projects to a zettascale system around 2035 consuming 500 megawatts at 2,140 gigaflops per watt (Nuclear Power Plant ~ 1 gigawatt).

The U.S. government database provided access to a treasure trove of sensitive data. "I can request information on anyone in the U.S.," one of the alleged hackers wrote:

Two men, one of whom previously presented themselves as an independent security researcher to Motherboard, allegedly went on a wide spanning hacking spree that included breaking into a federal U.S. law enforcement database; using a compromised Bangladeshi police officer's email to fraudulently requesting user data from a social media company; and even trying to buy services from a facial recognition company which doesn't sell products to the wider public.

[...] Sagar Steven Singh, 19, was arrested in Rhode Island on Tuesday; Nicholas Ceraolo, 25, remains at large with his location listed as Queens, New York, a press release from the United States Attorney's Office for the Eastern District of New York says. "Singh and Ceraolo unlawfully used a police officer's stolen password to access a restricted database maintained by a federal law enforcement agency that contains (among other data) detailed, nonpublic records of narcotics and currency seizures, as well as law enforcement intelligence reports," it states.

[...] That pursuit of personal information is what allegedly drew Singh and Ceraolo to breaking into various law enforcement accounts. In one case, the pair allegedly used a police officer's credentials to access a web portal maintained by a U.S. federal law enforcement agency.

Aztec farming calendar accurately tracked seasons, leap years:

Without clocks or modern tools, ancient Mexicans watched the sun to maintain a farming calendar that precisely tracked seasons and even adjusted for leap years.

Before the Spanish arrival in 1519, the Basin of Mexico's agricultural system fed a population that was extraordinarily large for the time. Whereas Seville, the largest urban center in Spain, had a population of fewer than 50,000, the Basin, now known as Mexico City, was home to as many as 3 million people.

To feed so many people in a region with a dry spring and summer monsoons required advanced understanding of when seasonal variations in weather would arrive. Planting too early, or too late, could have proved disastrous. The failure of any calendar to adjust for leap-year fluctuations could also have led to crop failure.

Though colonial chroniclers documented the use of a calendar, it was not previously understood how the Mexica, or Aztecs, were able to achieve such accuracy. New UC Riverside research, published in the Proceedings of the National Academy of Sciences, demonstrates how they did it. They used the mountains of the Basin as a solar observatory, keeping track of the sunrise against the peaks of the Sierra Nevada mountains.

"We concluded they must have stood at a single spot, looking eastwards from one day to another, to tell the time of year by watching the rising sun," said Exequiel Ezcurra, distinguished UCR professor of ecology who led the research.

To find that spot, the researchers studied Mexica manuscripts. These ancient texts referred to Mount Tlaloc, which lies east of the Basin. The research team explored the high mountains around the Basin and a temple at the mountain's summit. Using astronomical computer models, they confirmed that a long causeway structure at the temple aligns with the rising sun on Feb. 24, the first day of the Aztec new year.

https://arstechnica.com/information-technology/2023/03/chinese-search-giant-launches-ai-chatbot-with-prerecorded-demo/

Shares of Baidu fell as much as 10 percent on Thursday after the web search company showed only a pre-recorded video of its AI chatbot Ernie in the first public release of China's answer to ChatGPT.

The Beijing-based tech company has claimed Ernie will remake its business and for weeks talked up plans to incorporate generative artificial intelligence into its search engine and other products.

But on Thursday, millions of people tuning in to the event were left with little idea of whether Baidu's chatbot could compete with ChatGPT.
[...]
"We can only explore by ourselves. Training ChatGPT took OpenAI more than a year, and it took them another year to tune GPT-4," said one Baidu employee. "It means we're two years behind."

Baidu did not immediately respond to a request for comment.

The hypothesis could help in the search for other Earthlike worlds:

The leading explanation for the origin of the moon proposes that a Mars-sized planet, dubbed Theia, struck the nascent Earth, ejecting a cloud of debris into space that later coalesced into a satellite (SN: 3/2/18). New computer simulations suggest that purported remains of Theia deep inside the planet could have also triggered the onset of subduction, a hallmark of modern plate tectonics, geodynamicist Qian Yuan of Caltech reported March 13 at the Lunar and Planetary Science Conference.

[...] Many hypotheses have been proposed to explain the initiation of subduction, a tectonic process in which one plate slides under another (SN: 5/2/22; SN: 6/5/19; SN: 1/2/18). Yuan and his colleagues chose to focus on two continent-sized blobs of material in Earth's lower mantle known as large low-shear velocity provinces (SN: 5/12/16). These are regions through which seismic waves are known to move anomalously slow. Researchers had previously proposed these regions could have formed from old, subducted plates. But in 2021, Yuan and colleagues alternatively proposed that the mysterious masses could be the dense, sunken remnants of Theia.

[...] While the simulations suggest the large low-shear velocity provinces could have had a hand in starting subduction, it's not yet clear whether these masses came from Theia. "The features ... are a fairly recent discovery," says geodynamicist Laurent Montési of the University of Maryland in College Park. "They're very fascinating structures, with a very unknown origin." As such, he says, it's too early to say that Theia triggered plate tectonics.

"It's provoking. This material down there is something special," Montési says of the large low-shear velocity provinces. "But whether it has to be originally extraterrestrial, I don't think the case is made."

Tiny data center makes for a comfortable swim:

A data center about the size of a washing machine is being used to heat a public swimming pool in England.

Data centers' servers generate heat as they operate, and interest is growing in finding ways to harness it to cut energy costs and offset carbon emissions.

In this latest example, the computing technology has been placed inside a white box and surrounded by oil, which captures the heat before being pumped into a heat exchanger, according to a BBC report.

The setup is effective enough to heat a council-run swimming pool in Exmouth, about 150 miles west of London, to about 86 degrees Fahrenheit (30 degrees Celsius) for about 60% of the time, saving the operator thousands of dollars. And with energy costs rising sharply in the U.K., and councils looking for ways to save money, an initiative like this could be the difference between the pool staying open and closing down.

Behind the idea is U.K.-based tech startup Deep Green. In exchange for hosting its kit, Deep Green installs free digital boilers at pools and pays for the energy that they use. Meanwhile, tech firms pay Deep Green to use its computing power for various artificial intelligence and machine learning projects.

Hopes to avoid paying up for crushing a rival while helping Huawei and ZTE to prosper:

Qualcomm on Monday began an attempt to convince the European Union's Court of Justice that it should not pay a €242 million ($258 million) fine imposed on it for anti-competitive behavior.

The fine — worth about two percent of Qualcomm's 2022 profits — was levied against the US chipmaker in 2019. At the time, the European Commission found that Qualcomm had sold 3G baseband chipsets at a loss to harm British rival Icera's ability to compete.

[...] In order to prevent Nvidia-controlled Icera from claiming a larger slice of the market, the European Commission says Qualcomm began selling its UMTS chipsets to the likes of Huawei and ZTE at prices its rival couldn't match.

[...] The European Commission ultimately smacked Qualcomm with a €242 million fine for its behavior. As Qualcomm's profits reached $12.9 billion last year, the fine is significant but not very damaging.

Qualcomm is nevertheless trying to avoid paying the fine. In court Monday, Reuters reports that Qualcomm Attorney, Miguel Rato claimed the European Commission was on a "crusade" against the company. Rato also called into question the basis for the Commission's argument, arguing the specific market for 3G baseband chips accounted for less than a percent of the overall UMTS market at the time.

[...] Despite handing down several billion-dollar-plus fines for anticompetitive behavior over the past few years, the European Commission hasn't had great luck getting them to stick.

Intel escaped a $1.2 billion antitrust fine imposed by Brussels for offering hardware partners rebates for its x86 processors. Chipzilla even bribed German electronics retailer Media Saturn Holding to ensure it did not sell rival AMD's parts.

But after a years-long legal battle, Intel overturned the penalty and was told it didn't have to pay. To add insult to injury, Intel returned to court last spring demanding that the EU pay €593m ($623.5m) in interest charges.

JWST will help scientists investigate the troublesome dust budget surplus of the universe:

NASA released a new image captured by the James Webb Space Telescope (JWST), which depicts a star named "WR 124" that is located 15,000 light years away from Earth, in the Sagittarius constellation. WR 124 is a Wolf Rayet-type star, a rare kind of star which is among the most luminous, most massive, and most briefly detectable stars known, NASA explained.

WR 124 was actually one of the first observations made by JWST in June 2022, the space agency said, but the image has been unveiled just now. The Wolf-Rayet phase is a brief condition some stars go through during their lifetime before turning into supernovae, which makes Webb's observations a valuable asset to astronomers studying the life of stars.

WR 124 is 30 times the mass of our Sun, NASA said, and it has "shed" 10 Suns' worth of material so far. The ejected gas moves away from the central body and cools down, forming cosmic dust and glowing in the infrared light that is detectable by Webb's advanced instruments.

[...] Before Webb, astronomers investigating cosmic dust simply had no way to capture detailed images and information about a dust-rich environment like the WR 124 nebula. And dust, NASA said, plays an essential role in the inner working of the universe as it shelters forming stars, and gathers together to help shape planets, molecules and even the building blocks of life on Earth.

Dust is a fundamental element for our universe, and yet scientists still have to explain why the universe seemingly contains more dust than our current dust-formation theories can justify. The universe is "operating with a dust budget surplus," NASA remarked.

In high-risk contexts, a racing heart can make a formerly relaxed mouse nervous:

When you're stressed and anxious, you might feel your heart race. Is your heart racing because you're afraid? Or does your speeding heart itself contribute to your anxiety? Both could be true, a new study in mice suggests.

By artificially increasing the heart rates of mice, scientists were able to increase anxiety-like behaviors — ones that the team then calmed by turning off a particular part of the brain. The study, published in the March 9 Nature, shows that in high-risk contexts, a racing heart could go to your head and increase anxiety. The findings could offer a new angle for studying and, potentially, treating anxiety disorders.

The idea that body sensations might contribute to emotions in the brain goes back at least to one of the founders of psychology, William James, says Karl Deisseroth, a neuroscientist at Stanford University. In James' 1890 book The Principles of Psychology, he put forward the idea that emotion follows what the body experiences. "We feel sorry because we cry, angry because we strike, afraid because we tremble," James wrote.

The brain certainly can sense internal body signals, a phenomenon called interoception. But whether those sensations — like a racing heart — can contribute to emotion is difficult to prove, says Anna Beyeler, a neuroscientist at the French National Institute of Health and Medical Research in Bordeaux. She studies brain circuitry related to emotion and wrote a commentary on the new study but was not involved in the research. "I'm sure a lot of people have thought of doing these experiments, but no one really had the tools," she says.

[...] In the new study, Deisseroth and his colleagues used a light attached to a tiny vest over a mouse's genetically engineered heart to change the animal's heart rate. When the light was off, a mouse's heart pumped at about 600 beats per minute. But when the team turned on a light that flashed at 900 beats per minutes, the mouse's heartbeat followed suit. "It's a nice reasonable acceleration, [one a mouse] would encounter in a time of stress or fear," Deisseroth explains.

When the mice felt their hearts racing, they showed anxiety-like behavior. In risky scenarios — like open areas where a little mouse might be someone's lunch — the rodents slunk along the walls and lurked in darker corners. When pressing a lever for water that could sometimes be coupled with a mild shock, mice with normal heart rates still pressed without hesitation. But mice with racing hearts decided they'd rather go thirsty.

[...] Understanding the link between heart and head could eventually factor into how doctors treat panic and anxiety, Beyeler says. But the path between the lab and the clinic, she notes, is much more convoluted than that of the heart to the head.

The US government looks poised to force tech companies to do more about security:

The US government, worried about the continuing growth of cybercrime, ransomware, and countries including Russia, Iran, and North Korea hacking into government and private networks, is in the middle of drastically changing its cybersecurity strategy. No longer will it rely largely on prodding businesses and tech companies to voluntarily take basic security measures such as patching vulnerable systems to keep them updated.

Instead, it now wants to establish baseline security requirements for businesses and tech companies and to fine those that don't comply.

It's not just companies that use the systems who might eventually need to abide by the regulations. Companies that make and sell them, such as Microsoft, Apple, and others could be held accountable as well. Early indications are that the feds already have Microsoft in their crosshairs — they've warned the company that, at the moment, it doesn't appear to be up to the task.

[...] In theory, if those standards aren't met, fines would eventually be imposed. Glenn S. Gerstell, former general counsel of the National Security Agency, explained it this way to the Times: "In the cyberworld, we're finally saying that Ford is responsible for Pintos that burst into flames, because they didn't spend money on safety." That's a reference to the Ford Pinto frequently bursting into flames when rear-ended in the 1970s. That led to a spate of lawsuits and a ramp-up in federal auto safety regulations.

But cybersecurity requirements backed by fines aren't here yet. Dig into the new document and you'll find that because the new strategy is only a policy document, it doesn't have the bite of law behind it. For it to go fully into effect, two things need to happen. President Biden has to issue an executive order to enforce some of the requirements. And Congress needs to pass laws for the rest.

It's not clear when lawmakers might get around to moving on the issue, if ever, although Biden could issue an executive order for parts of it.

[...] So, what does all this have to do with Microsoft? Plenty. The feds have made clear they believe Microsoft has a long way to go before it meets basic cybersecurity recommendations. At least one top government security official has already publicly called out Microsoft for poor security practices.

Cybersecurity and Infrastructure Security Agency Director Jen Easterly recently criticized the Microsoft during a speech at Carnegie Mellon University. She said that only about one-quarter of Microsoft enterprise customers use multifactor authentication, a number she called "disappointing." That might not sound like much of a condemnation, but remember, this is the federal government we're talking about. It parses its words very carefully. "Disappointing" to them is the equivalent of "terrible job" anywhere else.

[...] Even without laws and executive orders, the company could be in trouble. The US government spends billions of dollars on Microsoft systems and services every year, a revenue stream that could be endangered if Microsoft doesn't adhere to the standards.

If you can detect any, it's too much:

On Tuesday, the Environmental Protection Agency announced that it had started the process that will see drinking water regulations place severe limits on the levels of several members of the PFAS (perfluoroalkyl and polyfluoroalkyl substances) chemical family. PFAS are widely used but have been associated with a wide range of health issues; their chemical stability has also earned them the term "forever chemicals." The agency is currently soliciting public feedback on rules that will mean that any detectable levels of two chemicals will be too much.

PFAS are a large group of chemicals that have uses in a wide range of products, including non-stick cooking pans, fire control foams, and waterproof clothing. They're primarily useful because of their water-repellant, hydrophobic nature. That nature also tends to keep them from taking part in chemical processes that might otherwise degrade them, so contamination problems tend to stick around long after any PFAS use. And that's bad, given that they seem to have a lot of negative effects on health—the EPA lists cancer risks, immune dysfunction, hormone signaling alterations, liver damage, and reproductive issues.

[...] The most striking thing about the proposal is that two of the chemicals, Perfluorooctanoic acid (PFOA) and Perfluorooctanesulfonic acid (PFOS) will be set at the limits of our current ability to detect them: four parts per trillion. In other words, if there's any sign of the chemicals present, it would be above the legal limit. (Both of these are acidic hydrocarbons where all of the hydrogen has been replaced by fluorine.)

A second set of related chemicals (PFNA, PFHXs, PFBS, and GenX Chemicals) will be regulated as a collective. Each will have limits set on the levels allowable. The levels of each will be calculated as a percentage of that limit, and the percentages totalled; if they exceed 100 percent, then the regulations will kick in.

As part of its earlier efforts, the EPA has already been providing grants to help water utilities set up to test for these chemicals. It also says that a variety of means of extracting these chemicals from water are now available.
