Climate change is already beginning to reshape global agriculture. India, the world's most populous country, looks particularly vulnerable: not just because of extreme weather, but because of government price controls. Fixing the problem is becoming more urgent, both for India and the world -- because India is a big food exporter, too. But politics makes that very difficult. From a report: In early December, India banned overseas shipments of onions until March in an effort to tame domestic prices. That is on top of export restrictions on rice, wheat and sugar already imposed over the past 18 months. And since India is the world's largest rice exporter, second-largest sugar and onion exporter, and a significant wheat producer, the bans are wreaking havoc globally. Thai rice prices had risen 14% and Vietnam rice prices had risen 22% from July levels by October, according to the International Food Policy Research Institute. Malaysia and the Philippines introduced their own measures to damp rising prices after India's curbs on rice exports in July.

Climate change will almost certainly pose a major problem for India's food supply. India's Ministry of Agriculture and Farmers Welfare recently estimated that, in the absence of adaptation measures, rain-fed rice yields could fall 20% by 2050. But domestic agricultural policies are almost as big a problem. At present, the government sets price floors for two dozen crops, guarantees purchases of certain agricultural products, and provides subsidies to farmers for fertilizers, electricity and transportation. All that might seem positive for food security, but on net it probably hampers investment and food supply growth. Price floors mean that supply might sometimes exceed final buyers' willingness to pay during slow times, leading to wastage. And restrictions on exports artificially depress domestic prices when global demand is hot. The government's own investigations have found that Agriculture Produce Marketing Committee laws, which regulate the trade of farmers' produce by providing licenses to buyers, commission agents and private markets, lead to cartelization and reduced competition.

A Japan Coast Guard plane and a Japan Airlines passenger jet collided at Tokyo's Haneda Airport but all 379 people on board the passenger jet were able to escape, Japan Airlines said. From a report: Five of the six people aboard the Coast Guard plane died in the crash, Japanese Prime Minister Fumio Kishida said. He said they were planning to deliver relief supplies to people affected by an earthquake on the Japan Sea coast on New Year's Day. Passengers in local television interviews said they saw a fire on the side of the Japan Airlines plane after it landed and were guided by cabin attendants to evacuate via escape chutes.

A Nobel Prize-winning labor market economist has cautioned younger generations against piling into studying science, technology, engineering, and mathematics (STEM) subjects, saying as "empathetic" and creative skills may thrive in a world dominated by artificial intelligence. From a report: Christopher Pissarides, professor of economics at the London School of Economics, said that workers in certain IT jobs risk sowing their "own seeds of self-destruction" by advancing AI that will eventually take the same jobs in the future. While Pissarides is an optimist on AI's overall impact on the jobs market, he raised concerns for those taking STEM subjects hoping to ride the coattails of the technological advances.

He said that despite rapid growth in the demand for STEM skills currently, jobs requiring more traditional face-to-face skills, such as in hospitality and healthcare, will still dominate the jobs market. "The skills that are needed now -- to collect the data, collate it, develop it, and use it to develop the next phase of AI or more to the point make AI more applicable for jobs -- will make the skills that are needed now obsolete because it will be doing the job," he said in an interview. "Despite the fact that you see growth, they're still not as numerous as might be required to have jobs for all those graduates coming out with STEM because that's what they want to do." He added, "This demand for these new IT skills, they contain their own seeds of self destruction."

AI represents a mixed blessing for the legal field, U.S. Supreme Court Chief Justice John Roberts said in a year-end report published on Sunday, urging "caution and humility" as the evolving technology transforms how judges and lawyers go about their work. From a report: Roberts struck an ambivalent tone in his 13-page report. He said AI had potential to increase access to justice for indigent litigants, revolutionize legal research and assist courts in resolving cases more quickly and cheaply while also pointing to privacy concerns and the current technology's inability to replicate human discretion.

"I predict that human judges will be around for a while," Roberts wrote. "But with equal confidence I predict that judicial work - particularly at the trial level - will be significantly affected by AI." The chief justice's commentary is his most significant discussion to date of the influence of AI on the law, and coincides with a number of lower courts contending with how best to adapt to a new technology capable of passing the bar exam but also prone to generating fictitious content, known as "hallucinations." Roberts emphasized that "any use of AI requires caution and humility." He mentioned an instance where AI hallucinations had led lawyers to cite non-existent cases in court papers, which the chief justice said is "always a bad idea." Roberts did not elaborate beyond saying the phenomenon "made headlines this year."

Hope Thelps writes: A number of films including the earliest ones featuring Mickey and Minnie Mouse finally enterd the public domain today. The BBC reports:

Steamboat Willie, a 1928 short film featuring early non-speaking versions of Mickey and Minnie, is widely seen as the moment that transformed Disney's fortunes and made cinema history.

Their images are now available to the public in the US, after Disney's copyright expired.

It means creatives like cartoonists can now rework and use the earliest versions of Mickey and Minnie.

In fact, anyone can use those versions without permission or cost.

But Disney warned that more modern versions of Mickey are still covered by copyright.

'We will, of course, continue to protect our rights in the more modern versions of Mickey Mouse and other works that remain subject to copyright,' the company said.

US copyright law says the rights to characters can be held for 95 years, which means the characters in Steamboat Willie entered the public domain on Monday, 1 January 2024.

Those works can now legally be shared, performed, reused, repurposed or sampled.

The early versions of Mickey and Minnie are just two of the works entering the public domain in the US on New Year's Day.

Other famous films, books, music and characters from 1928 are now also available to the American public.

They include Charlie Chaplin's silent romantic comedy The Circus; English author AA Milne's book The House at Pooh Corner, which introduced the character Tigger; Virginia Woolf's Orlando; and DH Lawrence's Lady Chatterley's Lover.

One of the country's most influential courts has asked the nation's top securities regulator for its views on an uncomfortable subject: whether audit reports by outside accounting firms actually matter. From a report: The court already ruled that, at least in one case, they didn't. That case, where an insurer overstated profits and an auditor signed off on its books, led to an investor lawsuit against the auditor that was dismissed. In its ruling, the court said the audit report was so general an investor wouldn't have relied on it. The decision could have broad ramifications for the Securities and Exchange Commission, which oversees corporate financial disclosures, and for the auditing industry, which charged about $17 billion last year for blessing the books of publicly listed companies in the U.S.

The ruling, by a three-judge panel of the Second U.S. Circuit Court of Appeals, prompted three former SEC officials to tell the court it got the answer wrong. They asked the court to reconsider its decision, noting that the SEC in a previous enforcement case had said that "few matters could be more important to investors" than whether a company's financial statements had been subjected to a properly conducted annual audit. The court responded by inviting the SEC to file a brief expressing its views on the former officials' arguments. The SEC in a court filing said that "the commission has an interest in ensuring its views on this issue are considered by the court." Its brief is due Feb. 16. The court ruling involved a lawsuit by investors over an audit gone wrong. AmTrust Financial Services, an insurance company, had overstated its profit, and BDO USA, its outside accounting firm, had blessed the numbers.

This summer 80 million Americans were experiencing 105-degree heat. And tonight the Washington Post identifies what was unique about 2023's weather: "the heat's all-consuming relentlessness.

"It went day by day, continent by continent, until people all over the map, whether in the Amazon or the Pacific islands or rural Greece, had glimpsed a climate future for which they are not prepared..." Even if its extremes are ultimately eclipsed, as seems inevitable, 2023 will mark a point when humanity crossed into a new climate era — an age of "global boiling," as United Nations Secretary General António Guterres called it. The year included the hottest single day on record (July 6) and the hottest ever month (July), not to mention the hottest June, the hottest August, the hottest September, the hottest October, the hottest November, and probably the hottest December. It included a day, November 17, when global temperatures, for the first time ever, reached 2 degrees Celsius above the preindustrial levels.

Discomfort, destruction, and death are the legacy of those records.

In Phoenix, a heat wave went on for so long, with 31 consecutive days above 110 Fahrenheit, that one NASA atmospheric scientist called it "mind-boggling." The surrounding county recorded a record number of heat deaths, nearly 600. In Brazil, drought sapped the normally lush Amazon, causing towns to ration drinking water, contributing to the deaths of endangered pink dolphins, and choking off the river-based system of travel and commerce... At one point the coastal Florida Keys waters reached 100 degrees, comparable to a hot tub...

One explanation for 2023's extreme heat is El Niño — a recurring oceanic phenomenon that warms the waters in the Pacific and causes a global ripple of consequences. But the scale of this year's heat — amplified by human-caused factors and the burning of fossil fuels — is still well beyond what most scientists had thought possible. Some have theorized that planetary warming may be accelerating. Others have said there's not enough evidence. What they agree upon, though, is that the earth is trending toward more extreme heat. That means that the experiences of 2023 can seem astonishing in the short-term but will one day look tame.

This year, then, will wind up as the first — and almost surely not the last — in which temperatures were at or near 1.5 Celsius above preindustrial levels, a threshold the Paris agreement has aimed to avoid.
The article includes two more sobering statistics:

• "The University of Maine's Climate Change Institute logs daily global temperatures going back to 1940. From this July on, almost without fail, every daily temperature in 2023 topped the daily temperature from the same date in any of the prior 83 years."

• "In Brazil, the Rio Negro, one of the Amazon's main tributaries, fell to its lowest level since record keeping began more than a century earlier."

"This year has been a major turning point in American health care," reports USA Today, "and patients can anticipate several major developments in the new year," including the beginning of a CRISPR "revolution" and "a new reckoning with drug prices that could change the landscape of the U.S. health care system for decades to come." Health care officials expect 2024 to bring a wave of innovation and change in medicine, treatment and public health... Many think 2024 could be the year more people have the tools to follow through on New Year's resolutions about weight loss. If they can afford them and manage to stick with them, people can turn to a new generation of remarkably effective weight-loss drugs, also called GLP-1s, which offer the potential for substantial weight loss...

In 2023, mental health issues became among the nation's most deadly, costly and pervasive health crises... The dearth of remedies has also paved the way for an unsuspecting class of drugs: psychedelics. MDMA, a party drug commonly known as "ecstasy," could win approval for legal distribution in 2024, as a treatment for post-traumatic stress disorder. Another psychedelic, a ketamine derivative eskatemine, sold as Spravato, was approved in 2019 to treat depression, but it is being treated like a conventional therapy that must be dosed regularly, not like a psychedelic that provides a long-lasting learning experience, said Matthew Johnson, an expert in psychedelics at Johns Hopkins University. MDMA (midomafetamine capsules) would be different, as the first true psychedelic to win FDA approval.

In a late-stage trial of patients with moderate or severe post-traumatic stress disorder, close to 90% showed clinically significant improvements four months after three treatments with MDMA and more than 70% no longer met the criteria for having the disorder, which represented "really impressive results," according to Matthew Johnson, an expert in psychedelics at Johns Hopkins University in Maryland. Psilocybin, known colloquially as "magic mushrooms," is also working its way through the federal approval process, but it likely won't come up before officials for another year, Johnson said. Psychedelics are something to keep an eye on in the future, as they're being used to treat an array of mental health issues: eskatimine for depression, MDMA for PTSD and psilocybin for addiction. Johnson said his research suggests that psychedelics will probably have a generalizable benefit across many mental health challenges in the years to come.
2024 will also be the first year America's drug-makers face new limits on how much they can increase prices for drugs covered by the federal health insurance program Medicare.

On December 15 GitHub declared end-of-life for its "hackable text editor" Atom. But Long-time Slashdot reader BrendaEM wants to remind everyone that after the announcement of Atom's sunset, "the community came together to keep Atom alive."

First there was the longstanding fork Atom-Community. But "due to differences in long-term goals for the editor, a new version was born: Pulsar."

From the Pulsar web site: Pulsar [sometimes referred to as Pulsar-Edit] aims to not only reach feature parity with the original Atom, but to bring Pulsar into the 21st century by updating the underlying architecture, and supporting modern features.

With many new features on the roadmap, once Pulsar is stable, it will be a true, Community-Based, Hackable, Text Editor.
"Of course, the user interface is much of the same," writes the blog Its FOSS, and it's cross-platform (supporting Linux, macOS, and Windows).

"The essentials seem to be there with the documentation, packages, and features like the ability to install packages from Git repositories..."

"For several years, thousands more high-earning, well-educated workers have left California than have moved in," reports the Los Angeles Times: Even though California has experienced lopsided out-migration for decades, the financial blow has been cushioned by the kinds of people moving into the state: The newcomers were generally better educated and earned more money than those who left. Not now: That long-standing trend has reversed...

The reversal, largely in response to the state's high taxes and soaring cost of living, has begun to damage California's overall economy. And, by cutting into tax revenues, has delivered punishing blows to state and local governments. State budget analysts recently projected a record $68 billion deficit in the next fiscal year because of a 25% drop in personal income tax collection in 2023. Some city, county and other local taxing authorities, particularly in the San Francisco Bay Area, have also recorded revenue declines. With investors and high-income taxpayers receiving substantial compensation in the form of stocks, last year's sluggish stock market accounted for a major share of the decline in state income tax revenues. So did layoffs and financial weakness in the tech sector. But rising unemployment in the state and the growing flight of professionals, business operators and others making good salaries were also notable contributors. And those factors will be harder to reverse, at least in the foreseeable future.

"There's a price to pay for the movement of middle- and upper-income people and corporations," said Joel Kotkin, a fellow at Chapman University who has researched the flight from California and the resulting threat to the state's fiscal outlook. "People who are leaving are taking their tax dollars with them."

The accelerating exodus from California in recent years, of both companies and people, has been well documented. The pandemic-induced rise in remote work, inflated housing prices and changing social conditions have spurred more Californians to pull up stakes... Moody's Analytics economist Mark Zandi analyzed moves in and out of California for The Times using Equifax credit data, to zero in on the age of the movers. He found that since the pandemic in early 2020, California has lost residents in every age group, but by a significant margin the biggest net out-migration came from those 35 to 44 years old. "This is probably motivated by the severe housing affordability crisis in California," Zandi said. "It's all but impossible for them to become homeowners in the state."

Eric McGhee, a senior fellow at the Public Policy Institute of California, who has written about demographic trends in migration, thinks the increased loss of higher-educated Californians to other states in recent years can be traced in significant part to the rise of remote work since the pandemic. As more employers call workers back to the office, and the share of fully remote work appears to have settled at around 10% of all employees, McGhee expects the net out-migration from California to slow...

Even if the outflow of residents reverts to pre-pandemic levels, the broader economic climate doesn't bode well for the state's budget and economic outlook, at least in the immediate future. The U.S. economy is slowing, and California's economy is decelerating faster than the nation's, with the state's unemployment rate, most recently at 4.8%, already a full point higher than nationwide.
The article clarifies that "it's not just the sheer numbers of people who have left. What's different is that in each of the prior two years, more than 250,000 Californians with at least a bachelor's degree moved out, while an average of 175,000 college graduates from other states settled in California, according to an analysis of census data by William Frey, a demographer at the Brookings Institution. In prior periods over the last two decades, that balance was about even or slightly in California's favor."

And besides billionaires, "There's been a broader exodus of ordinary Californians in the upper-income spectrum as well. In the tax filing years 2020 and 2021, the average gross income of taxpayers who had moved from California to another state was about $137,000. That was up from $75,000 in 2015 and 2016, according to migration and personal income data from the Internal Revenue Service."

It was a half a century ago that America passed legislation to protect vanishing species and their habitats — and since then, more than five dozen species have recovered. Just one example: In 1963 only 417 nesting pairs of bald eagles were found in the lower 48 states. But today there's more than 300,000 bald eagles, writes USA Today. "[T]hough its future remains uncertain, many experts say it remains one of the nation's crowning achievements."

But 1,252 species are still listed as endangered in the U.S. — 486 animals, and 766 plants — with 417 more species categorized as "threatened." The perils of the changing climate add urgency to calls for increased funding and more protection. In North Carolina, for example, the rising sea steadily creeps over a refuge that's home to the sole remaining wild red wolf population. Off New England, warming waters forced changes in the foraging habits of the endangered North Atlantic right whale, putting the massive marine mammals in harm's way more often... One in 5 plant and animal species in the nation remain at risk of extinction, says Susan Holmes, executive director of the Endangered Species Coalition. "Loss of habitat and climate change are absolutely some of the most important threats that we have."

"We are at what I would say is a pivotal moment with the threats of climate change," she said. "We have to act faster than ever in order to ensure that these species are going to thrive."

"Electric cars are already upending America," argues a new article in the Atlantic, citing booming sales and new models that are "finally starting to push us into the post-gas age." Americans are on track to buy a record 1.44 million of them in 2023, according to a forecast by BloombergNEF, about the same number sold from 2016 to 2021 total. "This was the year that EVs went from experiments, or technological demonstrations, and became mature vehicles," Gil Tal, the director of the Electric Vehicle Research Center at UC Davis, told me.... Nearly 40 new EVs have debuted since the start of 2022, and they are far more advanced than their ancestors. For $40,000, the Hyundai Ioniq 6, released this year, can get you 360 miles on a single charge; in 2018, for only a slightly lower cost, a Nissan Leaf couldn't go half that distance....

All of these EVs are genuinely great for the planet, spewing zero carbon from their tailpipes, but that's only a small part of what makes them different. In the EV age, cars are no longer just cars. They are computers... The million-plus new EVs on the road are ushering in a fundamental, maybe existential, change in how to even think about cars — no longer as machines, but as gadgets that plug in and charge like all the others in our life. The wonderful things about computers are coming to cars, and so are the terrible ones: apps that crash. Subscription hell. Cyberattacks... If cars are gadgets now, then carmakers are also now tech companies. An industry that has spent a century perfecting the internal combustion engine must now manufacture lithium-ion batteries and write the code to govern them. Imagine if a dentist had to pivot from filling cavities to performing open-heart surgery, and that's roughly what's going on here.

"The transition to EVs is completely changing everything," Loren McDonald, an EV consultant, told me. "It's changing the people that automotive companies have to hire and their skills. It's changing their suppliers, their factories, how they assemble and build them. And lots of automakers are struggling with that...." Job cuts are already happening, and more may come — even after the massive autoworker strike this year that largely hinged on electrification. Such a big financial investment is needed to electrify the car industry that from July to September, Ford lost $60,000 for every EV it sold. Or peel back one more onion layer to car dealerships: Tesla, Rivian, and other EV companies are selling directly to consumers, cutting them out. EVs also require little service compared with gas vehicles, a reality that has upset many dealers, who could lose their biggest source of profit.

None of this is the future. It is happening right now.

TechCrunch argues that in 2023, "established technologies relied on by millions hit a chaos curve, making people realize how beholden they are to a proprietary platform they have little control over." The OpenAI fiasco in November, where the ChatGPT hit-maker temporarily lost its co-founders, including CEO Sam Altman, created a whirlwind five days of chaos culminating in Altman returning to the OpenAI hotseat. But only after businesses that had built products atop OpenAI's GPT-X large language models (LLMs) started to question the prudence of going all-in on OpenAI, with "open" alternatives such as Meta's Llama-branded family of LLMs well-positioned to capitalize.

Even Google seemingly acknowledged that "open" might trump "proprietary" AI, with a leaked internal memo penned by a researcher that expressed fears that open source AI was on the front foot. "We have no moat, and neither does OpenAI," the memo noted.

Elsewhere, Adobe's $20 billion megabucks bid to buy rival Figma — a deal that eventually died due to regulatory headwinds — was a boon for open source Figma challenger Penpot, which saw signups surge amid a mad panic that Adobe might be about to unleash a corporate downpour on Figma's proverbial parade. And when cross-platform game engine Unity unveiled a controversial new fee structure, developers went berserk, calling the changes destructive and unfair. The fallout caused Unity to do a swift about turn, but only after a swathe of the developer community started checking out open source rival Godot, which also now has a commercial company driving core development.

CNN describes them as "towering waves," driven into California's coastline by powerful storms and "posing a significant risk to people and structures along the coast."

Monstrous, 20-foot-plus waves on Thursday crashed over seawalls and swept away and injured several people, forced rescues and sent a damaging surge of water through coastal California streets.

Dangerous waves continued to slam the coast on Friday, forcing beaches to close. All Ventura County beaches will be closed through New Year's Eve because of the 15- to 20-foot waves expected along the central and Southern California coasts through Saturday evening... Sea levels have risen along most of the California coastline over the past century, NOAA data shows, as global temperatures climb and melt glaciers and ice sheets. Higher sea levels are making coastal flooding events worse and will continue to do so in the future.

The first round of dangerous waves hit alongside high tide Thursday morning. Several people were injured by a huge wave that slammed into Pierpont in the Ventura Beach area... Nearly 20 people were briefly swept away in the incident and eight people were taken to the hospital, Ventura officials said.
One bystander even filmed what CNN calls a"monster" wave, "the surge sweeping people and vehicles down the street... The massive waves pummeling the coastline, reeking havoc, flooding streets and businesses."

CNN's report also includes footage from nearly 300 miles north, showing a wave flooding a beachfront restaurant's courtyard in Santa Cruz, California. ("I just feel bad for the restaurants," says one local. "I know they just went through renovations from the last time this happened.") CNN's original article notes the sheriff's office there briefly issued an evacuation warning for some areas for part of Thursday, including one "where seawater filled beachside roadways and pushed against some homes, CNN affiliate KION reported."

And CNN's video report concludes by noting that "Parts of the California coast could see towering waves through the weekend, coastal flood and high surf alerts stretching from the southern border to the Bay Area."

Chemists at a lab in Gloucertershire have developed a low carbon jet fuel made entirely from human sewage. James Hygate, Firefly Green Fuels CEO, said: "We wanted to find a really low-value feedstock that was highly abundant. And of course poo is abundant." The BBC reports: Independent tests by international aviation regulators found it was nearly identical to standard fossil jet fuel. Firefly's team worked with Cranfield University to examine the fuel's life cycle carbon impact. It concluded that Firefly's fuel has a 90% lower carbon footprint than standard jet fuel. Mr Hygate, who has been developing low-carbon fuels in Gloucestershire for 20 years, said although the new fuel was chemically just like fossil-based kerosene, it "has no fossil carbon, it's a fossil-free fuel."

"Of course energy would be used (in production), but when looking at the fuel's life cycle, a 90% saving is mind-blowing, so yes, we have to use energy but it is much lower compared to the production of fossil fuels," he added. [...] First, they create what they call "bio-crude." It looks like oil: thick, black, gloopy. Most importantly, it behaves like crude oil chemically. Dr Sergio Lima, who is also research director at Firefly Green Fuels, said: "What we are producing here is a fuel which is net zero." [...] The bio-kerosene is now being tested independently at the DLR Institute of Combustion Technology at the German Aerospace Center, working with Washington State University. Further future testing will also be carried out by the UK SAF (Sustainable Aviation Fuels) clearing House, based at University of Sheffield. First results have confirmed the fuel has near-identical chemical composition to A1 fossil jet fuel. The UK Department of Transport has awarded the team a 2 million pound research grant.

So they can make a test tube of kerosene in the lab. That is a long way from replacing kerosene in the world's airports. Mr Hygate has done his maths. Each human, he calculates, makes enough sewage in a year to produce 4-5 liters of bio jet fuel. To fly a passenger jet from London to New York would need the annual sewage of 10,000 people. And another 10,000 to come back. Put another way, the UK's total sewage supply would meet about 5% of the country's total aviation fuel demand. It may sound small, but he insists: "That's pretty exciting." "There's a 10% sustainable aviation fuel requirement, that's a legal mandate. And we could meet half of that with poo."

An anonymous reader quotes a report from the Associated Press: Social media companies collectively made over $11 billion in U.S. advertising revenue from minors last year, according to a study from the Harvard T.H. Chan School of Public Health published on Wednesday. The researchers say the findings show a need for government regulation of social media since the companies that stand to make money from children who use their platforms have failed to meaningfully self-regulate. They note such regulations, as well as greater transparency from tech companies, could help alleviate harms to youth mental health and curtail potentially harmful advertising practices that target children and adolescents.

To come up with the revenue figure, the researchers estimated the number of users under 18 on Facebook, Instagram, Snapchat, TikTok, X (formerly Twitter) and YouTube in 2022 based on population data from the U.S. Census and survey data from Common Sense Media and Pew Research. They then used data from research firm eMarketer, now called Insider Intelligence, and Qustodio, a parental control app, to estimate each platform's U.S. ad revenue in 2022 and the time children spent per day on each platform. After that, the researchers said they built a simulation model using the data to estimate how much ad revenue the platforms earned from minors in the U.S. The platforms themselves don't make public how much money they earn from minors. [...]

According to the Harvard study, YouTube derived the greatest ad revenue from users 12 and under ($959.1 million), followed by Instagram ($801.1 million) and Facebook ($137.2 million). Instagram, meanwhile, derived the greatest ad revenue from users aged 13-17 ($4 billion), followed by TikTok ($2 billion) and YouTube ($1.2 billion). The researchers also estimate that Snapchat derived the greatest share of its overall 2022 ad revenue from users under 18 (41%), followed by TikTok (35%), YouTube (27%), and Instagram (16%). "As concerns about youth mental health grow, more and more policymakers are trying to introduce legislation to curtail social media platform practices that may drive depression, anxiety, and disordered eating in young people," said senior author Bryn Austin, professor in the Department of Social and Behavioral Sciences. "Although social media platforms may claim that they can self-regulate their practices to reduce the harms to young people, they have yet to do so, and our study suggests they have overwhelming financial incentives to continue to delay taking meaningful steps to protect children."

Boeing instructed customer airlines to inspect their 787 Max jets for loose bolts, the Federal Aviation Administration (FAA) announced this week. From a report: The request comes after the manufacturer discovered two aircraft with missing bolts in the rudder control system, raising concerns about faults across all aircraft. "The issue identified on the particular airplane has been remedied," Boeing told CNN in a statement. "Out of an abundance of caution, we are recommending operators inspect their 737 Max airplanes and inform us of any findings." The inspection request entails a two-hour probe of the aircraft's safety-critical parts for each of the approximately 1,300 787 Max jets in service, the FAA said.

U.S. Energy Information Administration, in a press release: A new reactor at Georgia's Vogtle nuclear power plant is now in commercial operation, according to an announcement from Georgia Power, one of the plant's owners. It is the first new nuclear reactor to start up in the United States since the Tennessee Valley Authority's Watts Bar 2 was commissioned in 2016. The new 1,114 megawatt (MW) Unit 3 reactor joins two existing reactors at Plant Vogtle, which is jointly owned by Georgia Power and three other electric utility companies. The plant's first two reactors, with a combined 2,430 MW of nameplate capacity, came online in the late 1980s.

Georgia Power expects another similar-sized fourth reactor, Vogtle Unit 4, to begin operation sometime between November 2023 and March 2024. The two new reactors will make Plant Vogtle the largest nuclear power plant in the country, surpassing the 4,210 MW Palo Verde plant in Arizona. Construction at the two new reactor sites began in 2009. Originally expected to cost $14 billion and begin commercial operation in 2016 (Vogtle 3) and 2017 (Vogtle 4), the project ran into significant construction delays and cost overruns. The total cost of the project is now estimated at more than $30 billion.

An anonymous reader quotes a report from Ars Technica: Just before the holiday break, the US Energy Information Agency released data on the country's electrical generation. Because of delays in reporting, the monthly data runs through October, so it doesn't provide a complete picture of the changes we've seen in 2023. But some of the trends now seem locked in for the year: wind and solar are likely to be in a dead heat with coal, and all carbon-emissions-free sources combined will account for roughly 40 percent of US electricity production. [...]

At this point last year, coal had produced nearly 20 percent of the electricity in the US. This year, it's down to 16.2 percent, and only accounts for 15.5 percent of October's production. Wind and solar combined are presently at 16 percent of year-to-date production, meaning they're likely to be in a dead heat with coal this year and easily surpass it next year. Year-to-date, wind is largely unchanged since 2022, accounting for about 10 percent of total generation, and it's up to over 11 percent in the October data, so that's unlikely to change much by the end of the year. Solar has seen a significant change, going from five to six percent of the total electricity production (this figure includes both utility-scale generation and the EIA's estimate of residential production). And it's largely unchanged in October alone, suggesting that new construction is offsetting some of the seasonal decline.

Hydroelectric production has dropped by about six percent since last year, causing it to slip from 6.1 percent to 5.8 percent of the total production. Depending on the next couple of months, that may allow solar to pass hydro on the list of renewables. Combined, the three major renewables account for about 22 percent of year-to-date electricity generation, up about 0.5 percent since last year. They're up by even more in the October data, placing them well ahead of both nuclear and coal. Nuclear itself is largely unchanged, allowing it to pass coal thanks to the latter's decline. Its output has been boosted by a new, 1.1 Gigawatt reactor that come online this year (a second at the same site, Vogtle in Georgia, is set to start commercial production at any moment). But that's likely to be the end of new nuclear capacity for this decade; the challenge will be keeping existing plants open despite their age and high costs. If we combine nuclear and renewables under the umbrella of carbon-free generation, then that's up by nearly 1 percent since 2022 and is likely to surpass 40 percent for the first time. "The only thing that's keeping carbon-free power from growing faster is natural gas, which is the fastest-growing source of generation at the moment, going from 40 percent of the year-to-date total in 2022 to 43.3 percent this year," notes Ars.

"Outside of natural gas, however, all the trends in US generation are good, especially considering that the rise of renewable production would have seemed like an impossibility a decade ago. Unfortunately, the pace is currently too slow for the US to have a net-zero electric grid by the end of the decade."

Following policy adjustments by the U.S. Citizenship and Immigration Services (USCIS) in January, more foreign-born workers in science, technology, engineering, and math (STEM) fields are able to live and work permanently in the United States. "The jump comes after USCIS in January 2022 tweaked its guidance criteria relating to two visa categories available to STEM workers," reports Science Magazine. "One is the O-1A, a temporary visa for 'aliens of extraordinary ability' that often paves the way to a green card. The second, which bestows a green card on those with advanced STEM degrees, governs a subset of an EB-2 (employment-based) visa." From the report: The USCIS data, reported exclusively by ScienceInsider, show that the number of O-1A visas awarded in the first year of the revised guidance jumped by almost 30%, to 4570, and held steady in fiscal year 2023, which ended on 30 September. Similarly, the number of STEM EB-2 visas approved in 2022 after a "national interest" waiver shot up by 55% over 2021, to 70,240, and stayed at that level this year. "I'm seeing more aspiring and early-stage startup founders believe there's a way forward for them," says Silicon Valley immigration attorney Sophie Alcorn. She predicts the policy changes will result in "new technology startups that would not have otherwise been created."

President Joe Biden has long sought to make it easier for foreign-born STEM workers to remain in the country and use their talent to spur the U.S. economy. But under the terms of a 1990 law, only 140,000 employment-based green cards may be issued annually, and no more than 7% of those can go to citizens of any one country. The ceiling is well below the demand. And the country quotas have created decades-long queues for scientists and high-tech entrepreneurs born in India and China. The 2022 guidance doesn't alter those limits on employment-based green cards but clarifies the visa process for foreign-born scientists pending any significant changes to the 1990 law. The O-1A work visa, which can be renewed indefinitely, was designed to accelerate the path to a green card for foreign-born high-tech entrepreneurs.

Although there is no cap on the number of O-1A visas awarded, foreign-born scientists have largely ignored this option because it wasn't clear what metrics USCIS would use to assess their application. The 2022 guidance on O-1As removed that uncertainty by listing eight criteria -- including awards, peer-reviewed publications, and reviewing the work of other scientistsâ"and stipulating that applicants need to satisfy at least three of them. The second visa policy change affects those with advanced STEM degrees seeking the national interest waiver for an EB-2. Under the normal process of obtaining such a visa, the Department of Labor requires employers to first satisfy rules meant to protect U.S. workers from foreign competition, for example, by showing that the company has failed to find a qualified domestic worker and that the job will pay the prevailing wage. That time-consuming exercise can be waived if visa applicants can prove they are doing "exceptional" work of "substantial merit and national importance." But once again, the standard for determining whether the labor-force requirements can be waived was vague, so relatively few STEM workers chose that route. The 2022 USCIS guidance not only specifies criteria, which closely track those for the nonimmigrant, O-1A visa, but also allows scientists to sponsor themselves.
