Burned Investors Ask 'Where Were the Auditors?' A Court Says 'Who Cares?'

Slashdot - Mon, 2024-01-01 14:07
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.

Will AI Just Waste Everyone's Time?

Slashdot - Mon, 2024-01-01 12:34
"The events of 2023 showed that A.I. doesn't need to be that good in order to do damage," argues novelist Lincoln Michel in the New Republic: This March, news broke that the latest artificial intelligence models could pass the LSAT, SAT, and AP exams. It sparked another round of A.I. panic. The machines, it seemed, were already at peak human ability. Around that time, I conducted my own, more modest test. I asked a couple of A.I. programs to "write a six-word story about baby shoes," riffing on the famous (if apocryphal) Hemingway story. They failed but not in the way I expected. Bard gave me five words, and ChatGPT produced eight. I tried again, specifying "exactly six words," and received eight and then four words. What did it mean that A.I. could best top-tier lawyers yet fail preschool math? A year since the launch of ChatGPT, I wonder if the answer isn't just what it seems: A.I. is simultaneously impressive and pretty dumb. Maybe not as dumb as the NFT apes or Zuckerberg's Metaverse cubicle simulator, which Silicon Valley also promised would revolutionize all aspects of life. But at least half-dumb. One day A.I. passes the bar exam, and the next, lawyers are being fined for citing A.I.-invented laws. One second it's "the end of writing," the next it's recommending recipes for "mosquito-repellant roast potatoes." At best, A.I. is a mixed bag. (Since "artificial intelligence" is an intentionally vague term, I should specify I'm discussing "generative A.I." programs like ChatGPT and MidJourney that create text, images, and audio. Credit where credit is due: Branding unthinking, error-prone algorithms as "artificial intelligence" was a brilliant marketing coup).... The legal questions will be settled in court, and the discourse tends to get bogged down in semantic debates about "plagiarism" and "originality," but the essential truth of A.I. is clear: The largest corporations on earth ripped off generations of artists without permission or compensation to produce programs meant to rip us off even more. I believe A.I. defenders know this is unethical, which is why they distract us with fan fiction about the future. If A.I. is the key to a gleaming utopia or else robot-induced extinction, what does it matter if a few poets and painters got bilked along the way? It's possible a souped-up Microsoft Clippy will morph into SkyNet in a couple of years. It's also possible the technology plateaus, like how self-driving cars are perpetually a few years away from taking over our roads. Even if the technology advances, A.I. costs lots of money, and once investors stop subsidizing its use, A.I. — or at least quality A.I. — may prove cost-prohibitive for most tasks.... A year into ChatGPT, I'm less concerned A.I. will replace human artists anytime soon. Some enjoy using A.I. themselves, but I'm not sure many want to consume (much less pay for) A.I. "art" generated by others. The much-hyped A.I.-authored books have been flops, and few readers are flocking to websites that pivoted to A.I. Last month, Sports Illustrated was so embarrassed by a report they published A.I. articles that they apologized and promised to investigate. Say what you want about NFTs, but at least people were willing to pay for them. "A.I. can write book reviews no one reads of A.I. novels no one buys, generate playlists no one listens to of A.I. songs no one hears, and create A.I. images no one looks at for websites no one visits. "This seems to be the future A.I. promises. Endless content generated by robots, enjoyed by no one, clogging up everything, and wasting everyone's time."

2023 Will Be Remembered as the Year Climate Change Arrived

Slashdot - Mon, 2024-01-01 08:00
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."

What Were Slashdot's Top 10 Stories of 2023?

Slashdot - Mon, 2024-01-01 05:00
Slashdot's 10 most-visited stories of 2023 seemed to touch on all the themes of the year, with a story about AI, two about electric cars, two stories about Linux, and two about the Rust programming language. And at the top of this list, the #1 story of the year drew over 100,000 views... Can California's Power Grid Handle a 15x Increase in Electric Cars?

Will 2024 Bring a 'Major Turning Point' in US Health Care?

Slashdot - Mon, 2024-01-01 02:08
"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.

Since the Demise of Atom, 'Pulsar' Offers an Alternative Code Editor

Slashdot - Mon, 2024-01-01 01:08
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..."

Navajo Nation President Asks NASA to Delay Moon Launch Over Possible Human Remains

Slashdot - Sun, 2023-12-31 23:42
"Navajo Nation President Buu Nygren has asked NASA to delay a scheduled launch to the Moon that could include cremated remains," reports Arizona Public Radio station KNAU: Nygren says he recently learned of the January 8 launch of the Vulcan Centaur carrying the Peregrine Mission One. The lander will carry some payloads from a company known to provide memorial services by shipping human cremated remains to the Moon. Nygren wants the launch delayed and the tribe consulted immediately. He noted the Moon is sacred to numerous Indigenous cultures and that depositing human remains on it is "tantamount to desecration." NASA previously came under fire after the ashes of former geologist and planetary scientist Eugene Shoemaker were sent to the Moon in 1998. Then-Navajo Nation President Albert Hale said the action was a gross insensitivity to the beliefs of many Native Americans. NASA later apologized and promised to consult with tribes before authorizing any similar missions in the future.

The Wealthiest Californians are Leaving the State, Hurting the Economy, Statistics Confirm

Slashdot - Sun, 2023-12-31 22:42
"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."

'Aquaman 2' Has Made Just 12% of What 'Aquaman 1' Earned

Slashdot - Sun, 2023-12-31 21:10
Forbes writes: "I am not sure there could have been a more ignominious end to the DCEU." Aquaman 2 opened with $27.7 million domestically, well under half the $67.8 million opening for the original Aquaman. But it's the overall box office totals that are especially dire, as the film has made just over $138.5 million worldwide. That is about 12% of Aquaman 1's final total of $1.1 billion in 2018, where it is the DCEU's highest grossing entry. The counter to this is that it perhaps is too soon to run these numbers, as it just came out right? Well, a few extra factors to consider. It is already out in a ton of major markets, so there are relatively few potential surges that can still happen outside places like Korea and New Zealand, which can only add so much. Most importantly Aquaman 2 has already launched in China, where it made $30 million in its opening, again, far below the original's opening at $93 million there, doing even worse there than domestically, in context. Aquaman 1 went on to make $292 million in China, a figure Aquaman 2 will not come within a mile of. Next, what DC, and many blockbusters, have been doing lately are these incredibly short theatrical windows, so the clock is ticking quickly... Of course this is not exclusive to DC, as we have an extremely direct comparison over at Marvel with The Marvels, which at a $205.6 million global gross, the final figure, that is 18% of Captain Marvel's $1.13 billion total. Aquaman 2 has the advantage of being a true sequel, not a team-up piece from other TV shows you theoretically needed to watch beforehand, but it also has the disadvantage of being the last dying gasp of the DCEU coming after a string of other high profile box office failures from Shazam 2 to Blue Beetle. There was really no way it was going to avoid its fate, even if it did review well (which it didn't, as at 35% on Rotten Tomatoes, it's one of the DCEU's lowest rated films).

Is the Internet About to Get Weird Again?

Slashdot - Sun, 2023-12-31 18:34
Long-time tech entrepreneur Anil Dash predicts a big shift in the digital landscape in 2024. And "regular internet users — not just the world's tech tycoons — may be the ones who decide how it goes." The first thing to understand about this new era of the internet is that power is, undoubtedly, shifting. For example, regulators are now part of the story — an ironic shift for anyone who was around in the dot com days. In the E.U., tech giants like Apple are being forced to hold their noses and embrace mandated changes like opening up their devices to allow alternate app stores to provide apps to consumers. This could be good news, increasing consumer choice and possibly enabling different business models — how about mobile games that aren't constantly pestering gamers for in-app purchases? Back in the U.S., a shocking judgment in Epic Games' (that's the Fortnite folks') lawsuit against Google leaves us with the promise that Android phones might open up in a similar way. That's not just good news for the billions of people who own smartphones. It's part of a sea change for the coders and designers who build the apps, sites, and games we all use. For an entire generation, the imagination of people making the web has been hemmed in by the control of a handful of giant companies that have had enormous control over things like search results, or app stores, or ad platforms, or payment systems. Going back to the more free-for-all nature of the Nineties internet could mean we see a proliferation of unexpected, strange new products and services. Back then, a lot of technology was created by local communities or people with a shared interest, and it was as likely that cool things would be invented by universities and non-profits and eccentric lone creators as they were to be made by giant corporations.... In that era, people could even make their own little social networks, so the conversations and content you found on an online forum or discussion were as likely to have been hosted by the efforts of one lone creator than to have come from some giant corporate conglomerate. It was a more democratized internet, and while the world can't return to that level of simplicity, we're seeing signs of a modern revisiting of some of those ideas. Dash's article (published in Rolling Stone) ends with examples of "people who had been quietly keeping the spirit of the human, personal, creative internet alive...seeing a resurgence now that the web is up for grabs again. " Digital artist Everest Pipkin The School for Poetic Computation (which Dash describes as "an eccentric, deeply charming, self-organized school for people who want to combine art and technology and a social conscience.") Mask On Zone, "a collaboration with the artist and coder Ritu Ghiya, which gives demonstrators and protesters in-context guidance on how to avoid surveillance." There's projects and tools from makers like Stefan Bohacek, Darius Kazemi, and Elan Kiderman Ullendorff (including Youtune ("a stream of relatively unviewed original songs posted to YouTube.") Dash concludes that "We're seeing the biggest return to that human-run, personal-scale web that we've witnessed since the turn of the millennium, with enough momentum that it's likely that 2024 is the first year since then that many people have the experience of making a new connection or seeing something go viral on a platform that's being run by a regular person instead of a commercial entity. "It's going to make a lot of new things possible..." A big thank-you for submitting the article to long-time Slashdot reader, DrunkenTerror.

Source-Based Gentoo Linux Goes Binary

Slashdot - Sun, 2023-12-31 17:34
While Gentoo Linux is best-known as source-based Linux distribution, "our package manager, Portage, already for years also has support for binary packages," according to its web page. It notes that source- and binary-based package installations can be freely mixed. But now... To speed up working with slow hardware and for overall convenience, we're now also offering binary packages for download and direct installation! For most architectures, this is limited to the core system and weekly updates — not so for amd64 and arm64 however. There we've got a stunning >20 GByte of packages on our mirrors, from LibreOffice to KDE Plasma and from Gnome to Docker. Gentoo stable, updated daily. Enjoy! "We have a rather neat binary package guide on our Wiki that goes into much more detail..." the announcement points out. The packages are cryptographically signed with the same key as the stages.

How 'Digital Twin' Technology Is Revolutionizing the Auto Industry

Slashdot - Sun, 2023-12-31 16:34
"Digital twin technology is one of the most significant disruptors of global manufacturing seen this century," argues Motor Trend, "and the automobile industry is embracing it in a big way." Roughly three-quarters of auto manufacturers are using digital twins as part of their vehicle development process, evolving not only how they design and develop new cars but also the way they monitor them, fix them, and even build them... Nvidia, best known for its consumer graphics cards, also has a digital twin solution, called Omniverse, which manufacturers such as Mercedes-Benz are using to design their manufacturing processes. "Their factory planners now have every single element in the factory that they can then put in that virtual digital twin first, lay it all out, and then operate it," Danny Shapiro, VP of automotive at Nvidia said. At that point, those planners can run the entire manufacturing process virtually, ensuring every conveyor feeds the next step in the process, identifying and addressing factory floor headaches long before production begins... Software developers can run their solutions within digital twins. That includes the code at the lowest level, basic stuff that controls ignition timing within the engine for example, all the way up to the highest level, like touchscreens responding to user inputs. "We're not just simulating the operation outside the car, but the user experience," Nvidia's Shapiro said. "We can simulate and basically run the real software that would be running in that car and display it on the screens." By bringing all these systems together virtually, developers can find and solve issues earlier, preventing costly development delays or, worse yet, buggy releases... Using unique identifiers, manufacturers can effectively create internal digital copies of vehicles that have been produced. Those copies can be used for ongoing tests and verifications, helping to anticipate things like required maintenance or susceptibility to part failures. By using telematics, in-car services that remotely communicate a car's status back to the manufacturer in real-time, these digital twins can be updated to match the real thing. "By monitoring tire health, tire grip, vehicle weight distribution, and other critical parameters, engineers can anticipate potential problems and schedule maintenance proactively, reducing downtime and extending the vehicle's lifespan," Tactile Mobility's Tzur said.

How a Cray-1 Supercomputer Compares to a Raspberry Pi

Slashdot - Sun, 2023-12-31 15:34
Roy Longbottom worked for the U.K. covernment's Central Computer Agency from 1960 to 1993, and "from 1972 to 2022 I produced and ran computer benchmarking and stress testing programs..." Known as the official design authority for the Whetstone benchmark), Longbottom writes that "In 2019 (aged 84), I was recruited as a voluntary member of Raspberry Pi pre-release Alpha testing team." And this week — now at age 87 — Longbottom has created a web page titled "Cray 1 supercomputer performance comparisons with home computers, phones and tablets." And one statistic really captures the impact of our decades of technological progress. "In 1978, the Cray 1 supercomputer cost $7 Million, weighed 10,500 pounds and had a 115 kilowatt power supply. It was, by far, the fastest computer in the world. The Raspberry Pi costs around $70 (CPU board, case, power supply, SD card), weighs a few ounces, uses a 5 watt power supply and is more than 4.5 times faster than the Cray 1."

Could We Build a Concert Venue in Space?

Slashdot - Sun, 2023-12-31 12:34
What would happen if we built a concert venue in near-Earth orbit? A science policy journalist explores the question in the Washington Post: Forget U2 in the Las Vegas Sphere. Take me to a real concert in the round, where I can float 360 degrees around the stage, watching a guitarist shred from the perspective of a fly and inventing dance moves that Earth's gravity would forbid. Before you dismiss this as a hallucination, consider that we're on the cusp of a new era of space travel. Engineer and space architect Ariel Ekblaw, founder of MIT's Space Exploration Initiative, says that within a decade, a trip off the planet could become as accessible as a first-class airline ticket — and that, in 15 or 20 years, we can expect space hotels in near-Earth orbit. She's betting on it, having founded a nonprofit to design spherical, modular habitats that can assemble themselves in space so as to be lightweight and compact at launch, much like the James Webb Space Telescope that NASA vaulted into deep space two years ago. "The first era of space travel was about survival," she told me as I recently toured her lab. "We're transitioning now to build spaces that are friendlier and more welcoming so that people can thrive in space as opposed to just survive." There's no reason, Ekblaw said, that a concert hall can't be one of those structures. The article ultimately calls this "an impulse for space travel I can get behind: curiosity about who we are and what more we can create when we reach beyond Earth. This is the realm of not just scientists and engineers but of all kinds of dreamers. It's a rendition of space exploration that can engage anyone to imagine what's possible."

'Behold - the Best Space Images of 2023'

Slashdot - Sun, 2023-12-31 08:34
As the year comes to a close, "one constant, reliable source of awe and beauty is the sky over our head..." writes astronomer Phil Plait in Scientific America "And every year we see new things, or old things in new ways, and I've been set the wonderful task of selecting my favorites and relaying them and their import to you." End-of-year lists, especially those displaying astronomical imagery, tend to be splashy and colorful. That's understandable, but what they sometimes miss are the more subtle photographs, those that hide momentous discoveries in minor visual details or offer fresh perspectives on familiar objects. They may not leap off the page, but they still have an impact. That's what I've kept in mind while sorting through this year's celestial treasure trove. This gallery is by no means complete, but it shows what I think are some of the most interesting astronomical portraits to have emerged in 2023. No gallery such as this would be complete without something from the James Webb Space Telescope (JWST), our newest infrared eye on the sky. This monster observatory has already brought so many small revolutions to astronomy that picking one from the past year is no small task. Should it be a baby star throwing an immense tantrum or a massive old star shedding material at colossal rates before it inevitably explodes as a supernova? Or should it be a map of a mind-stomping 100,000 galaxies? Well, how about something very, very different — such as the skeletal structure of a nearby galaxy's intricate web of dust [also displayed at the top of Scientiic American's article]...? [I]t has a beautiful spiral structure and shows the effects of a smaller galaxy colliding with it. In the phenomenally sharp and decidedly eerie false-color view from JWST's Mid-Infrared Instrument, we see countless clouds of cosmic dust in a skeletonlike pattern. Each of these clouds is made up of small grains of rocky and sooty carbon-based molecules expelled by dying stars... Astronomers captured this image to better understand how stars are born in stellar nurseries and how they evolve over time.

20% of America's Plants and Animals are At Risk of Extinction

Slashdot - Sun, 2023-12-31 05:35
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."

How Electric Cars are Already Upending America

Slashdot - Sun, 2023-12-31 02:45
"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.

A New Type of Jet Engine Could Revive Supersonic Air Travel

Slashdot - Sun, 2023-12-31 00:45
"Since the 1960s engineers around the world have been fiddling with a novel type of jet called a rotating detonation engine (RDE), but it has never got beyond the experimental stage," reports the Economist. "That could be about to change." GE Aerospace, one of the world's biggest producers of jet engines, recently announced it was developing a working version. Earlier this year America's Defence Advanced Research Projects Agency awarded a $29m contract to Raytheon, part of RTX, another big aerospace group, to develop an RDE called Gambit. Both engines would be used to propel missiles, overcoming the range and speed limitations of current propulsion systems, including rockets and existing types of jet engines. However, if the companies are successful in getting them to work, RDEs might have a much broader role in aviation — including the possibility of helping revive supersonic air travel. In a nutshell, an RDE "replaces fire with a controlled explosion", explains Kareem Ahmed, an expert in advanced aerospace engines at the University of Central Florida. In technical terms, this is because a jet engine relies on the combustion of oxygen and fuel, which is a subsonic reaction that scientists call deflagration. Detonation, by comparison, is a high-energy explosion that takes place at supersonic speeds. As a result it is a more powerful and potentially a more efficient way of producing thrust, the force that drives an aircraft forward... By modifying an aircraft's fuselage and wings, engineers believe they can reduce the boom's impact on the ground below. Such work will help to determine whether or not future supersonic passenger planes will, like Concorde, be restricted to flying beyond the speed of sound only over oceans.
