Court holds that state officials violated the First Amendment when they ordered retired engineer Wayne Nutt to stop talking about math in public:

Chief Judge Richard Myers issued an opinion holding that the North Carolina Board of Examiners for Engineers and Surveyors violated the First Amendment when it ordered retired engineer Wayne Nutt to stop expressing opinions about engineering without a state license. Nutt, represented by the Institute for Justice (IJ), filed the lawsuit after the Board sent him a series of threatening letters ordering him to stop publicly offering opinions about engineering without a license, on pain of potential criminal punishment. Today's ruling confirms that those letters—and the law they were based on—violate the First Amendment.

"State licensing boards nationwide increasingly act as if they are boards of censors, deciding who may or may not speak about the topics they regulate," explained IJ Attorney Joe Gay. "Today's ruling is a powerful reminder that in this country we rely on people to decide who they want to listen to. We don't rely on government boards to decide who gets to speak."

[...] "The First Amendment protects everyone's right to speak their minds, whether they're talking about politics or talking about math," explained IJ Deputy Director of Litigation Robert McNamara. "Regulators often seem to forget that basic fact, but we always stand ready to remind them."

Scientists have been looking for health-promoting microbes in the feces of people from traditional communities—some of whom feel exploited:

We’re all teeming with microbes. We’ve got guts full of them, and they’re crawling all over our skin. These tiny, ancient life forms have evolved with us. And over the last couple of decades, scientists have come to realize just how important they are to our health and well-being. They help extract nutrients from our food, influence the way our immune systems work, and can even send signals to our brains that play a role in our mental health. 

But some researchers believe our microbiomes are in crisis—casualties of an increasingly sanitized, industrialized, and antimicrobial way of life. Disturbances in the collections of microbes we host have been associated with a whole host of diseases, ranging from arthritis to Alzheimer’s.

“It’s very clear in industrialized nations we have lost many species that were probably fundamental to human evolution,” says Justin Sonnenburg, a microbiome scientist at Stanford University. “They’ve just become extinct.” Some have seemingly disappeared before we’ve even had a chance to figure out what they do.

Some might not be completely gone, though. Scientists believe many might still be hiding inside the intestines of people who don’t live in the polluted, processed, and antimicrobial-laden environment that most of the rest of us share. They’ve been studying the feces of people from hunter-gatherer societies like the Yanomami, an Indigenous group in the Amazon, who appear to still have some of the microbes that other people have lost. 

And so the race is on to find those missing microbes. Both academics and companies are building catalogues of microbes seen in hunter-gatherer societies, and attempting to re-create this microbial brew as a treatment for people in industrialized societies. The hope is that with the proper mix of microbes, many people might gain protection from disorders, like depression and metabolic disease, that seem to affect people living in industrialized societies at much higher rates. But there is a rather major catch: we don’t know whether those in hunter-gatherer societies really do have “healthier” microbiomes—and if they do, whether the benefits could be shared with others.

At the same time, members of the communities being studied say some projects aren’t being done ethically or equitably. Even recent research projects have taken biological samples without consent and attempted to artificially manipulate the way hunter-gatherers eat and live, says Shani Mangola, a member of the much-studied Hadza society in Tanzania. He and others are concerned about the risk of what’s called biopiracy—taking natural resources from poorer countries for the benefit of wealthier ones. 

[...] Those of us who live in industrialized societies have changed the habitats of our gut microbes to a fairly drastic degree. We use antibiotics and antibacterials and eat a diet of novel ingredients and heavily processed foods.

As a result, microbiologists believe, we’ve been killing off some of the microbes that humans once carried. Compare modern-day fecal samples with ancient ones, and there are clear differences. The microbiomes of today are less diverse, with more of some bugs and fewer of others. Scientists believe that some of the ones that are missing have very important functions, like breaking down certain carbohydrates and producing chemicals that might be important for gut health.

Some people call it a great extinction. And the decline in these microbes has been linked to an uptick in a range of chronic diseases like asthma, diabetes, and inflammatory bowel disease. 

Aleksandar Kostic, a microbiologist at Harvard Medical School, wants to know what microbes our ancestors did have. A couple of years ago, he and his colleagues looked for microbial DNA in eight samples of ancient human feces collected from the southwestern United States and Mexico. These remains, known as paleofeces, were estimated to be between 1,000 and 2,000 years old. 

When Kostic and his colleagues compared the fossilized poo with modern-day microbiome samples from people from eight different countries, they found significant differences. But some samples were more similar than others. 

Specifically, modern-day samples from people who live in “nonindustrialized” communities had a lot more in common with the ancient feces. “The paleofeces and the Yanomami samples almost matched,” says Emma Allen-Vercoe, a microbiologist at the University of Guelph in Canada, who was not an author of the study. 

[...] “Taking advantage of an Indigenous population and using their microbes to try to reinstate health in somebody from a wealthy, industrialized nation, I think, is a problematic thing to do,” says Sonnenburg. He doesn’t think such experiments should never be done—just that the ethical implications should be thoroughly explored, and that the Hadza should be fully informed and consent to the research.

[...] The Yanomami have had experiences similar to those of the Hadza. “They’re angry that scientists have come, taken their samples, and never come back,” says Good. The results of the research aren’t shared with them. And neither are any potential profits. 

He is working to redress that with the Yanomami Foundation, a nonprofit organization that aims to conduct ethical research with the Yanomami by seeking consent and addressing the wishes and needs of the community. 

[...] Even if these ethical problems are ever solved, scientific ones will endure. For a start, while we believe that microbial diversity is important, we haven’t firmly established anything other than a correlation between health and a more diverse microbiome. Is this diversity responsible for a lack of chronic disease, or is it a consequence of a particular diet that might not even benefit everyone in the same way? 

We know that antibiotics can disrupt our gut health. But the details of the link between microbial diversity and health are still largely a mystery. Even if you assume diversity is good, it’s not clear how much is needed—or what’s the best way to foster it. 

Not too long ago, the line of thinking was that the more diverse your diet, the better. Now Allen-Vercoe isn’t so sure. People who live in big cities have such a wide range of food options that they can eat a different meal every day of the month. But they are thought to have some of the “least healthy” microbiomes, she says.

And for all we know, people in industrialized societies may have lost microbes because they no longer serve any purpose in our diet. Maybe they would be likely to cause an infection. Maybe doing away with some of them is really no great loss after all. Maybe the rise of chronic illness is only correlated with the loss of microbial diversity, and other factors are responsible.

Because microbes evolve and adapt to their environments, we should expect the microbiomes of people who live in cities to look different from those of people who live in forests. “There is no archetypal microbiome that everyone should [aspire to],” says Good. “Your microbiome is a reflection of your intimate interaction with your surrounding ecosystem, including the foliage, the air, the water, the food—and that all plays a role in driving the diversity of the microbiome within your gut and on your skin.”

Arthur T Knackerbracket has processed the following story:

Hyperloop One, the futuristic transportation startup that promised to whisk us through nearly airless tubes at airline speeds, is shutting down, according to Bloomberg.

The company is selling off its assets, closing down its offices, and laying off employees. It will formally close at the end of the year, at which point all of its intellectual property will shift to its majority stakeholder, major Dubai port operator DP World. Whoever buys the test track in the Nevada desert will have one hell of a Slip ‘N Slide if they want it.

Since its founding in 2014, the company raised around $450 million in venture capital funds and other investments. While there is still a small smattering of startups trying to build hyperloops, the demise of one of the biggest hyperloop companies signals the end of the dream that originated with Elon Musk’s so-called “alpha paper” in 2013.

Whoever buys the test track in the Nevada desert will have one hell of a Slip ‘N Slide if they want it

Musk theorized that aerodynamic aluminum capsules filled with passengers or cargo could be propelled through a nearly airless tube at speeds of up to 760mph. These tubes, either raised on pylons or sunk beneath the earth, could be built either within or between cities. He called it a “fifth mode of transportation” and argued it could help change the way we live, work, trade, and travel.

The most eye-catching scenario he proposed was a trip from Los Angeles to San Francisco in only 30 minutes. The idea captured the imaginations of engineers and investors across the world.

[...] Critics said that while the hyperloop may be technically feasible, it still only amounts to vaporware. It’s been called a “utopian vision” that would be financially impossible to achieve. It’s one of those technologies that is also “just around the corner,” according to its boosters — despite outwardly appearing to still be years away from completion. In 2017, Virgin Hyperloop’s top executives told The Verge they expect to see “working hyperloops around the world... by 2020.” That deadline was later pushed to 2021.

[...] Today, no full-scale hyperloops exist anywhere in the world. Musk’s test tunnel in California is gone. The man himself has become more enamored with endorsing antisemitic theories than solving the problem of car traffic.

The Boring Company, Musk’s tunneling operation, is still digging underground passageways in Las Vegas — but for Teslas, not hyperloops. The future, it would seem, is nearly the same as the present.

Arthur T Knackerbracket has processed the following story:

Your snack habit may be even more calorie-dense than you think, recent research suggests. A study estimated that snacking contributes to around 20% of an average American’s daily caloric intake, and these snacks often add little nutritional value. The scientists found, though, that people with type 2 diabetes seem to eat fewer snack-related calories.

The study was led by scientists from The Ohio State University. Research has consistently shown that Americans’ diets have gotten bigger over time. And it’s likely that these extra calories have contributed to a rise in obesity and other metabolic disorders like type 2 diabetes. But the study authors say that little work has been done to specifically quantify the snacking patterns of adults with type 2.

[...] The researchers found that people reported eating an average two snacks a day, no matter their diabetes status. Those without type 2 consumed roughly 500 calories from their snacks, while those with diagnosed diabetes or prediabetes ate slightly fewer. Overall, between 19.5% and 22.4% of a person’s daily calorie intake came from snacking, or about the same amount we might get from a full meal. And people’s snacks were typically not filled with the healthiest ingredients. Nearly half of the calories consumed in-between meals came from foods considered snacks and sweets, for instance, while 15% of these calories were from alcohol beverages in those without diabetes.

[...] The findings suggest that people with diabetes often make a conscious effort to cut down on snacking, and that further indicates that people are willing to listen to and heed advice on what kinds of foods they should eat or avoid, the study authors say. But they note that everyone could benefit from these lessons.

“Diabetes education looks like it’s working, but we might need to bump education back to people who are at risk for diabetes and even to people with normal blood glucose levels to start improving dietary behaviors before people develop chronic disease,” said study author Christopher Taylor, professor of medical dietetics in the School of Health and Rehabilitation Sciences at OSU, in a statement from the university.

(A bit on the long side, but well worth the read. --Marty)

The secret sauce for Taiwan's chip superstardom:

When 23-year-old Shih Chin-tay boarded a plane for the United States in the summer of 1969, he was flying to a different world.

He grew up in a fishing village surrounded by sugarcane fields. He had attended university in Taiwan's capital Taipei, then a city of dusty streets and grey apartment buildings where people rarely owned cars.

[...] Today's Taipei is rich and hip. High-speed trains zip passengers along the west coast of the island at 350km/h (218mph). Taipei 101 - briefly the tallest building in the world - towers over the city, an emblem of its prosperity.

Much of that is down to a tiny device no larger than a fingernail. The silicon semiconductor - wafer-thin and best-known now as a chip - sits at the heart of every technology we use, from iPhones to airplanes.

Taiwan now makes more than half the chips that power our lives. Its biggest manufacturer, Taiwan Semiconductor Manufacturing Company (TSMC), is the ninth-most valuable business in the world.

That makes Taiwan nearly irreplaceable - and vulnerable. China, fearing it could be cut off from the most advanced chips, is spending billions to steal Taiwan's crown. Or it could take the island, as it has repeatedly threatened to do.

But Taiwan's path to chip superstardom will not be easy to replicate - the island has a secret sauce, honed through decades of laborious work by its engineers. Plus, the manufacturing relies on a web of economic ties that the escalating US-China rivalry is now trying to undo.

[...] Back then, he quickly realised that taking on US and Japanese giants at their own game was a losing proposition. Instead TSMC would only manufacture chips for others, and not design its own.

This "foundry model", which was unheard of in 1987, changed the landscape of the industry and paved the way for Taiwan to become the pack leader.

[...] "Rule number one at TSMC is don't compete with your customers," Dr Shih says.

[...] Taiwan's extraordinary success - the island ships more than half of those trillion-plus chips, and nearly all of the most advanced ones - has been driven by its mastery of volume. In other words, Taiwanese manufacturing is incredibly efficient.

[...] Over time Taiwanese manufacturers have managed to cram more and more circuits into mind-bogglingly smaller spaces. Using the latest extreme-ultraviolet light lithography machines, TSMC can etch 100 billion circuits on to a single microprocessor, or over 100 million circuits per square millimetre.

Why are Taiwanese companies so good at this? No-one seems to know exactly why.

Dr Shih thinks it's simple: "We had brand new facilities, with the most up-to-date equipment. We recruited the best engineers. Even the machine operators were highly skilled. And then we didn't just import technology, we absorbed the lessons from our American teachers and applied continuous improvement."

A young man who spent several years working at one of Taiwan's largest electronics companies agrees: "I think Taiwan's companies are bad at making big breakthroughs in technology. But they are very good at taking someone else's idea and making it better. This can be done by trial and error, continuously tweaking small things."

[...] But the young man, who did not want to reveal his name, or that of the company, says Taiwanese companies have another advantage.

"Compared to software engineers in the US, even at the best companies here, engineers are paid quite badly," he said. "But compared to other industries in Taiwan the pay is good. So, if you work for a big electronic company after a few years, you'll be able to get a mortgage, buy a car. You'll be able to get married. So, people suck it up."

[...] "If people weren't willing to do the job the company would be finished. It's because people are willing to put up with hardship that these companies succeed."

[...] Dr Shih says those who are seeking to forcibly restructure global chip production misunderstand its success.

"If you look at the history of semiconductors, no one country dominates this industry," he says. "Taiwan may dominate the manufacturing sector. But there is a very long supply chain and innovation from every part of it contributes to the growth of the industry. "

[...] Dr Shih is doubtful Beijing can recreate this supply chain - from materials to design to high-end production - inside China.

"If they want to create a different model then I wish them luck," he says with a shrug. "Because if you really want innovation, you need everyone to work together from all around the world. It's not one company or one country."

He is just as doubtful about cutting China out as the US has been doing.

"I think that's probably a major mistake," he says. "When I look back, I feel lucky to have witnessed the extraordinary growth of Taiwan's economy and this long period of peace. Now I see conflict in other parts of the world, and I worry it may come to Asia.

"I hope people appreciate the precious effort that we made and won't destroy it."

from the precious-ICs-flood-my-soul dept.

Arthur T Knackerbracket has processed the following story:

Although China cannot flood the global market with chips produced with cutting-edge fabrication technologies, strong subsidies for the semiconductor sector in China make it possible for the country to flood the market with chips made on legacy process technologies, thus undercutting much-needed sales that generate revenue that is vital for R&D at Western firms. This tactic could spur the U.S. government to impose tariffs on products using mature processing nodes, reports Bloomberg.

[...] China is known for providing hefty funds to its chipmakers. For example, China-based SMIC invested $24 billion in capital expenditures from 2020 to 2023 with support from banks, local governments, and state-controlled funds, far exceeding its earnings in the period, according to Nikkei. Other semiconductor companies also have generous support from the government, which is how they can quickly expand production capacity using tools that they can procure without any limitations and start producing chips like display driver ICs (DDICs) or power management ICs (PMICs) that are sold in billions of units every year.

[...] The survey's findings are set to guide the U.S. in formulating responses that could include the imposition of tariffs or the use of other trade tools to counteract China's aggressive expansion in the semiconductor industry. Commerce Secretary Gina Raimondo has already indicated that the U.S. is ready to use every tool it has to stop China from flooding the market with low-cost legacy chips. However, she clarified that the most stringent export controls would remain reserved for more advanced process technologies and not for these older generation nodes, so Chinese companies will still be able to procure legacy chipmaking tools.

Motor Trend reports on recent gov't. actions that will lead to drunk & drowsy driving detection built into new cars, https://www.motortrend.com/news/nhtsa-anti-drunk-driving-tech-rules-coming/

The National Highway Traffic Safety Administration (NHTSA) has, after years of voicing its intent, officially submitted an advanced notice of proposed rulemaking surrounding anti-drunk-driving technology. This marks the first formal salvo in its bid to ensure every new vehicle sold in America comes with some form of built-in inebriation detection and possibly an interlock that prevents the car from being driven if the driver is determined to be impaired.

Alcohol-related vehicle crashes are among the leading cause of injury and death on America's roadways, which already have seen a precipitous backsliding in term of safety in recent years. After decades of progress reducing roadway deaths, America has seen car-related fatalities soar, leaving policymakers stumped and scrambling for solutions.

[...] Per NHTSA's notice: "This document initiates rulemaking that would gather the information necessary to develop performance requirements and require that new passenger motor vehicles be equipped with advanced drunk and impaired driving prevention technology through a new Federal Motor Vehicle Safety Standard (FMVSS)." The agency adds that:

"The Infrastructure Investment and Jobs Act (Bipartisan Infrastructure Law or BIL) directs NHTSA to issue a final rule establishing a Federal Motor Vehicle Safety Standard (FMVSS) that requires new passenger vehicles to have 'advanced drunk and impaired driving prevention technology' by 2024. The BIL also provides that an FMVSS should be issued only if it meets the requirements of the National Traffic and Motor Vehicle Safety Act."

Most likely solution are cameras that watch the driver for warning signs, these already exist on some cars. It will be interesting to see if other solutions are also put forward.

MotorTrend then opines,

Of course, this opens many cans of worms. Will NHTSA advocate a warning system onboard that alerts the driver that they're impaired? An ignition interlock that prevents the car from starting and driving at all? What if there are false readings? A sober passenger taking whatever onboard test exists in the driver's place? One also could imagine the sort of arguments advocates of unfettered freedom might come up with: Someone eluding an attacker, but who had previously had a drink, being locked out of their means of escape due to technological misunderstanding. Of course, these concerns must be weighed against the more than 10,000 preventable deaths from drunk drivers annually.

Lawmakers want HHS to revise health privacy law to require warrants:

All of the big pharmacy chains in the US hand over sensitive medical records to law enforcement without a warrant—and some will do so without even running the requests by a legal professional, according to a congressional investigation.

The revelation raises grave medical privacy concerns, particularly in a post-Dobbs era in which many states are working to criminalize reproductive health care. Even if people in states with restrictive laws cross state lines for care, pharmacists in massive chains, such as CVS, can access records across borders.

Lawmakers noted the pharmacies' policies for releasing medical records in a letter dated Tuesday to the Department of Health and Human Services (HHS) Secretary Xavier Becerra. The letter—signed by Sen. Ron Wyden (D-Ore.), Rep. Pramila Jayapal (D-Wash.), and Rep. Sara Jacobs (D-Calif.)—said their investigation pulled information from briefings with eight big prescription drug suppliers.

All eight of the pharmacies said they do not require law enforcement to have a warrant prior to sharing private and sensitive medical records, which can include the prescription drugs a person used or uses and their medical conditions. Instead, all the pharmacies hand over such information with nothing more than a subpoena, which can be issued by government agencies and does not require review or approval by a judge.

[...] For now, HIPAA regulations grant patients the right to know who is accessing their health records. But, to do so, patients have to specifically request that information—and almost no one does that. "Last year, CVS Health, the largest pharmacy in the nation by total prescription revenue, only received a single-digit number of such consumer requests," the lawmakers noted.

"The average American is likely unaware that this is even a problem," the lawmakers said.

Novel Terrapin attack uses prefix truncation to downgrade the security of SSH channels:

Sometime around the start of 1995, an unknown person planted a password sniffer on the network backbone of Finland's Helsinki University of Technology (now known as Aalto University). Once in place, this piece of dedicated hardware surreptitiously inhaled thousands of user names and passwords before it was finally discovered. Some of the credentials belonged to employees of a company run by Tatu Ylönen, who was also a database researcher at the university.

The event proved to be seminal, not just for Ylönen's company but for the entire world. Until that point, people like Ylönen connected to networks using tools which implemented protocols such as Telnet, rlogin, rcp, and rsh. All of these transmitted passwords (and all other data) as plaintext, providing an endless stream of valuable information to sniffers. Ylönen, who at the time knew little about implementing strong cryptography in code, set out to develop the Secure Shell Protocol (SSH) in early 1995, about three months after the discovery of the password sniffer.

[...] Ylönen submitted SSH to the Internet Engineering Taskforce in 1996, and it quickly became an almost ubiquitous tool for remotely connecting computers. Today, it's hard to overstate the importance of the protocol, which underpins the security of apps used inside millions of organizations, including cloud environments crucial to Google, Amazon, Facebook, and other large companies.

[...] Now, nearly 30 years later, researchers have devised an attack with the potential to undermine, if not cripple, cryptographic SSH protections that the networking world takes for granted.

Named Terrapin, the new hack works only when an attacker has an active adversary-in-the middle position on the connection between the admins and the network they remotely connect to. Also known as a man-in-the-middle or MitM attack, this occurs when an attacker secretly positioned between two parties intercepts communications and assumes the identity of both the recipient and the sender. This provides the ability to both intercept and to alter communications. While this position can be difficult for an attacker to achieve, it's one of the scenarios from which SSH was thought to have immunity.

For Terrapin to be viable, the connection it interferes with also must be secured by either "ChaCha20-Poly1305" or "CBC with Encrypt-then-MAC," both of which are cipher modes added to the SSH protocol (in 2013 and 2012, respectively). A scan performed by the researchers found that 77 percent of SSH servers exposed to the Internet support at least one of the vulnerable encryption modes, while 57 percent of them list a vulnerable encryption mode as the preferred choice.

At its core, Terrapin works by altering or corrupting information transmitted in the SSH data stream during the handshake—the earliest stage of a connection, when the two parties negotiate the encryption parameters they will use to establish a secure connection. The attack targets the BPP, short for Binary Packet Protocol, which is designed to ensure that adversaries with an active position can't add or drop messages exchanged during the handshake. Terrapin relies on prefix truncation, a class of attack that removes specific messages at the very beginning of a data stream.

[...] The researchers note that they aren't the first people to describe a prefix truncation attack on a network protocol by manipulating sequence numbers. In 2015, researcher Cédric Fournet envisioned a similar attack on a draft of the upcoming version 1.3 of TLS. Fournet's technique increased sequence numbers by fragmenting messages rather than injecting them as Terrapin does. (Terrapin injects an IGNORE message to asymmetrically increase the sequence number on one side of the communication.) Fournet's attack was deemed theoretical because the manipulation in this case was likely to cause TLS handshakes to fail. The possibility of a successful exploit nonetheless prompted engineers to follow Fournet's advice to revert back to 1.2's practice of resetting record-layer sequence numbers to 0 whenever new keys were installed.

In response to recommendations provided by the researchers ahead of the publication of Monday's paper, the developers of SSH software, including the nearly ubiquitous OpenSSH, have updated their implementations to support an optional strict key exchange. It provides for sequence number resets and also prevents an attacker's capability to inject packets during the initial unencrypted handshake. For the fix to take effect, both client and server must support this backward-compatible change.

[...] People who want to know if the SSH client or server they use is vulnerable to Terrapin can use a custom scanner developed by the researchers. It connects to a server or monitors the incoming client connection to determine whether one of the vulnerable encryption modes is available and if the countermeasure requiring a strict key exchange is supported. The scanner doesn't perform a full-fledged handshake or carry out the attack.

[...] While the risk Terrapin poses varies, it invalidates proofs published in 2016 that concluded such attacks weren't possible. The real lesson is that practical evaluations, like the one provided in Monday's research, are crucial for revealing previously overlooked flaws in such proofs.

"In any case, proofs need to be updated over time to reflect changes and extensions to the protocol," the researchers wrote. "Although we suggest backward-compatible countermeasures to stop our attacks, we note that the security of the SSH protocol would benefit from a redesign from scratch, guided by all findings and insights from both practical and theoretical security analysis, in a similar manner as was done for TLS 1.3."

The US Surgeon General has published his 2023 advisory on social control media and youth mental health [warning for PDF]. The report's scope is only on the health and mental health effects, not the weaponized nature of the phenomenon. The body of the report is 17 pages long and includes a call to action.

Extreme, inappropriate, and harmful content continues to be easily and widely accessible by children and adolescents. This can be spread through direct pushes, unwanted content exchanges, and algorithmic designs. In certain tragic cases, childhood deaths have been linked to suicide- and self-harm-related content and risk-taking challenges on social media platforms. This content may be especially risky for children and adolescents who are already experiencing mental health difficulties. Despite social media providing a sense of community for some, a systematic review of more than two dozen studies found that some social media platforms show live depictions of self-harm acts like partial asphyxiation, leading to seizures, and cutting, leading to significant bleeding. Further, these studies found that discussing or showing this content can normalize such behaviors, including through the formation of suicide pacts and posting of self-harm models for others to follow.

Social media may also perpetuate body dissatisfaction, disordered eating behaviors, social comparison, and low self-esteem, especially among adolescent girls. A synthesis of 20 studies demonstrated a significant relationship between social media use and body image concerns and eating disorders, with social comparison as a potential contributing factor. Social comparison driven by social media is associated with body dissatisfaction, disordered eating, and depressive symptoms. When asked about the impact of social media on their body image, nearly half (46%) of adolescents aged 13–17 said social media makes them feel worse, 40% said it makes them feel neither better nor worse, and only 14% said it makes them feel better.

from the waste-not-want-not dept.

Arthur T Knackerbracket has processed the following story:

When it is very windy, the grid cannot handle the extra power generated. Wind farms are paid to switch off and gas-powered stations are paid to fire up. The cost is passed on to consumers.

The government said major reforms will halve the time it takes to build energy networks to cope with extra wind power.

Energy regulator Ofgem announced new rules in November, which it said would speed up grid connections.

Most of the UK's offshore wind farms are in England - Dogger Bank off the coast of Yorkshire is the largest in the world. Meanwhile, around half of onshore wind farms are in Scotland but most electricity is used in south-east England.

Carbon Tracker said the main problem in getting electricity to where it is needed is a bottleneck in transmission between Scotland and England.

The practice of switching off wind farms and ramping up power stations is known as "wind curtailment" and the costs are passed on to consumers, it said.

[...] "The problem is, there are not enough cables. The logical solution would be to build more grid infrastructure," said Lorenzo Sani, analyst at Carbon Tracker.

"It's not even that expensive," he added, compared with mounting wind curtailment costs.

[...] However, historically it has taken between 10 and 15 years for new transmission cables to be approved.

[...] In November, the government set out a plan to reduce the time it takes to build new infrastructure from 14 to seven years, "speeding up grid connections, supporting thousands of jobs and reducing electricity bills for households across Great Britain", a spokesperson said.

Energy regulator Ofgem said there was a "long queue" of energy projects "which could generate almost 400GW of electricity - well in excess of what is needed to power the entire British energy system".

The watchdog said new rules "will allow stalled or speculative 'zombie' projects to be forced out of the queue, meaning viable projects can be connected quicker".

Mr Sani from Carbon Tracker said it was unclear how much difference these projects would make before 2030.

Arthur T Knackerbracket has processed the following story:

AMD has finally launched its Instinct MI300X accelerators, a new generation of server GPUs designed to provide compelling performance levels for generative AI workloads and other high-performance computing (HPC) applications. MI300X is faster than H100, AMD said earlier this month, but Nvidia tried to refute the competitor's statements with new benchmarks released a couple of days ago.

Nvidia tested its H100 accelerators with TensorRT-LLM, an open-source library and SDK designed to efficiently accelerate generative AI algorithms. According to the GPU company, TensorRT-LLM was able to run 2x faster on H100 than on AMD's MI300X with proper optimizations.

AMD is now providing its own version of the story, refuting Nvidia's statements about H100 superiority. Nvidia used TensorRT-LLM on H100, instead of vLLM used in AMD benchmarks, while comparing performance of FP16 datatype on AMD Instinct MI300X to FP8 datatype on H100. Furthermore, Team Green inverted AMD's published performance data from relative latency numbers to absolute throughput.

AMD suggests that Nvidia tried to rig the game, while it is still busy identifying new paths to unlock performance and raw power on Instinct MI300 accelerators. The company provided the latest performance levels achieved by the Llama 70B chatbot model on MI300X, showing an even higher edge over Nvidia's H100.

By using the vLLM language model for both accelerators, MI300X was able to achieve 2.1x the performance of H100 thanks to the latest optimizations in AMD's software stack (ROCm). The company highlighted a 1.4x performance advantage over H100 (with equivalent datatype and library setup) earlier in December. vLLM was chosen because of its broad adoption within the community and the ability to run on both GPU architectures.

The technologies, policies, and commitments providing a glimmer of hope in an otherwise gloomy year:

It's been the hottest year on record, with January through November clocking in at 1.46 °C (2.62 °F) warmer on average than preindustrial temperatures. Meanwhile, emissions from fossil fuels hit a new high—36.8 billion metric tons of carbon dioxide, 1.1% more than in 2022.

Scientists are loudly warning that the world is running out of time to avoid dangerous warming levels. The picture is grim. But if you know where to look, there are a few bright spots shining through the darkness.

[...] EVs are on track to make up 15.5% of automotive sales this year, according to BNEF. Between battery electric vehicles and plug-in hybrids, this new growth means there are almost 41 million passenger EVs on the road. China has the largest share of EVs in the world, making up nearly a quarter of the global fleet.

[...] While many signs are positive, it's not all rosy for electric vehicles. Growth in sales slowed between 2022 and 2023, and changing demand has some automakers slowing production for models like the Ford F-150 Lightning. Charging infrastructure isn't available or reliable enough in most markets, a problem that has become one of the biggest barriers to EV adoption.

Cars are being sold at a record pace and road emissions are still going up, so EV sales need to accelerate to make a dent in transportation's climate impact. But EVs' progress so far seems to be an encouraging story of a new climate-friendly technology becoming a mainstream option. Let's hope it keeps going in 2024—all gas, no brakes.

[...] Another encouraging development on the otherwise daunting topic of climate change is the growing recognition that cutting methane pollution is one of the most powerful levers we can pull to limit global warming over the coming years.

Carbon dioxide has long overshadowed methane, since we emit so much more of it. But methane traps about 80 times as much heat over a 20-year period and accounts for at least a quarter of overall warming above our preindustrial past.

On the other hand, it also breaks down far faster in the atmosphere. Together, those qualities mean that rapid cuts in methane emissions today could deliver an outsize impact on climate change, potentially shaving a quarter-degree off total warming by midcentury. That could easily make the difference between a planet that does or doesn't tip past 2 °C.

So it was encouraging to finally hear the head of the US Environmental Protection Agency announce, at the recent UN climate conference, that it will soon require oil and gas companies to monitor methane emissions across their pipelines, wells, and facilities and sharply reduce venting, flaring, and leaks.

As federal regulations go, preventing emissions of a combustible, planet-warming superpolllutant that isn't even producing anything of economic value is truly about the least we can ask of an industry. But it's a step forward that promises to eliminate the warming equivalent of about 1.5 billion metric tons of carbon dioxide by 2038.

[...] As with every issue when it comes to climate change, none of this is enough, too much of it is voluntary, and complications abound. But these announcements, along with other signs of progress, are slowly adding up to a less grim future, while reminding us all that we're capable of achieving even more.

While the world scrambles to slow our emissions, it's becoming ever more clear that the damage from climate change is happening in the present tense, with wildfires, floods, and heat waves making headlines.

So it was welcome news that this year's UN climate conference started with a historic milestone for vulnerable countries struggling to deal with these problems. On day one of the talks, the long-anticipated loss and damage fund was officially launched.

[...] The purpose of this fund is to help poor and developing countries address the increasing harm from climate disasters. Many of these countries—which have contributed the least amount of emissions—are the most vulnerable to climate impacts and often lack adequate resources to manage them. The funds can help them rebuild in the aftermath of events like drought or floods, and improve a nation's ability to withstand future catastrophes.

[...] By the end of COP28 on December 12, countries had collectively committed nearly $800 million. The United Arab Emirates and Germany each pledged $100 million, the United Kingdom offered $75 million, and the United States contributed $17.5 million.

Those numbers sound big, but a few people have made a sports analogy that puts this all in perspective. On December 9, a baseball player, Shohei Ohtani, signed a $700 million contract with the LA Dodgers. The fact that a worldwide effort to address climate change is even remotely comparable to the amount spent by a sports team on a single athlete should be a global embarrassment.

[...] That being said, the fund is still a step toward equitable climate resilience. Now the focus is on continuing to scale up the commitments and making the funds more accessible to those who need them.

Now Photoshop giant needs to cough up that $1B break-up fee:

Adobe has decided to abandon its $20 billion acquisition of Figma in a concession to regulatory pressure in Europe, the United Kingdom, and the United States.

The two software makers said on Monday they had reached a joint decision to cancel the pending deal, which was announced in September, 2022.

"It’s not the outcome we had hoped for, but despite thousands of hours spent with regulators around the world detailing differences between our businesses, our products, and the markets we serve, we no longer see a path toward regulatory approval of the deal," said Dylan Field, co-founder and CEO of Figma, in a statement.

Shantanu Narayen, chair and CEO of Adobe, offered a similar concession speech: "Adobe and Figma strongly disagree with the recent regulatory findings, but we believe it is in our respective best interests to move forward independently."

Doing so will cost Adobe $1 billion – that's the amount of the breakup fee due to Figma for Adobe's failure to complete the deal. Everyone knows Adobe is the home of Photoshop, Illustrator, and other tools; Figma, meanwhile, makes software primarily for planning and sketching out graphic designs in a collaborative way with others.

[...] The cancellation of the acquisition is one of the higher profile antitrust blows struck by regulators against Big Tech in several years of political jawboning on both sides of the Atlantic about the need to tame technology firms.

[...] Alex Haffner, competition partner at UK law firm Fladgate, told The Register in an email that the announcement reflects broad regulatory consensus that the tie-up would have harmed competition.

"People seeing today’s announcement by Adobe may view it as an anti Big Tech stance from the CMA, following on from the Microsoft/Activision case," said Haffner. "But on this occasion, it is clear that it was both the CMA and the European Commission who were expecting significant concessions in the form of a structural divestment in order to clear the deal and that was not a price Adobe could pay.

"Moreover, unlike in the Microsoft case, Figma appears to be quite willing to retain its independence (and take any break up fee it negotiated from Adobe). Certainly the regulatory landscape for Big Tech has become somewhat more complicated in recent times, but, on this occasion at least, the regulators appear to be talking with a unified voice in their opposition to the proposed deal."
