"One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up," write two U.K. researchers in the Conversation: Galaxies rotate much faster than predicted by applying Newton's law of gravity to their visible matter, despite those laws working well everywhere in the Solar System. To prevent galaxies from flying apart, some additional gravity is needed. This is why the idea of an invisible substance called dark matter was first proposed. But nobody has ever seen the stuff. And there are no particles in the hugely successful Standard Model of particle physics that could be the dark matter — it must be something quite exotic.

This has led to the rival idea that the galactic discrepancies are caused instead by a breakdown of Newton's laws. The most successful such idea is known as Milgromian dynamics or Mond [also known as modified Newtonian dynamics], proposed by Israeli physicist Mordehai Milgrom in 1982. But our recent research shows this theory is in trouble...

Due to a quirk of Mond, the gravity from the rest of our galaxy should cause Saturn's orbit to deviate from the Newtonian expectation in a subtle way. This can be tested by timing radio pulses between Earth and Cassini. Since Cassini was orbiting Saturn, this helped to measure the Earth-Saturn distance and allowed us to precisely track Saturn's orbit. But Cassini did not find any anomaly of the kind expected in Mond. Newton still works well for Saturn... Another test is provided by wide binary stars — two stars that orbit a shared centre several thousand AU apart. Mond predicted that such stars should orbit around each other 20% faster than expected with Newton's laws. But one of us, Indranil Banik, recently led a very detailed study that rules out this prediction. The chance of Mond being right given these results is the same as a fair coin landing heads up 190 times in a row. Results from yet another team show that Mond also fails to explain small bodies in the distant outer Solar System...

The standard dark matter model of cosmology isn't perfect, however. There are things it struggles to explain, from the universe's expansion rate to giant cosmic structures. So we may not yet have the perfect model. It seems dark matter is here to stay, but its nature may be different to what the Standard Model suggests. Or gravity may indeed be stronger than we think — but on very large scales only.
"Ultimately though, Mond, as presently formulated, cannot be considered a viable alternative to dark matter any more," the researchers conclude. "We may not like it, but the dark side still holds sway."

Zitchas writes: The practice of having games require a connection to a publisher's server -- whether it is to check for a license or to access plug-ins and DLC -- is an increasingly common thing in computer software; and many people are concerned that at some point in the future the publisher will shut down their server, and effectively render the person who paid for the game left with something that no longer functions. This has already happened to some games and software

Concerned citizens in Canada are taking the issue to their Parliament in order to push for a law that will mandate that when the server-side support for software is discontinued, companies must leave it in a functional state and remove mandatory connections to servers -- services that no longer exist. Perhaps even more importantly, the petition also asks government to pass a law prohibiting EULA's from forcing users to agree to waiving their right to this. Unfortunately, the petition is only open to citizens of Canada, so the rest of us are out of luck. Considering the potential benefits to the rest of the world if they enact legislation that does this, though, it might be worth suggesting to any of your Canadian friends to go sign the petition.

Several large-scale, human-driven changes to the planet -- including climate change, the loss of biodiversity and the spread of invasive species -- are making infectious diseases more dangerous to people, animals and plants, according to a new study. From a report: Scientists have documented these effects before in more targeted studies that have focused on specific diseases and ecosystems. For instance, they have found that a warming climate may be helping malaria expand in Africa and that a decline in wildlife diversity may be boosting Lyme disease cases in North America. But the new research, a meta-analysis of nearly 1,000 previous studies, suggests that these patterns are relatively consistent around the globe and across the tree of life.

"It's a big step forward in the science," said Colin Carlson, a biologist at Georgetown University, who was not an author of the new analysis. "This paper is one of the strongest pieces of evidence that I think has been published that shows how important it is health systems start getting ready to exist in a world with climate change, with biodiversity loss." In what is likely to come as a more surprising finding, the researchers also found that urbanization decreased the risk of infectious disease. The new analysis, which was published in Nature on Wednesday, focused on five "global change drivers" that are altering ecosystems across the planet: biodiversity change, climate change, chemical pollution, the introduction of nonnative species and habitat loss or change.

An anonymous reader quotes a report from 404 Media: Pokemon Go players are creating a headache for members of the open source map tool OpenStreetMaps by adding fake beaches where they don't exist in hopes of more easily catching Wigletts, a Pokemon that only spawns on beaches. OpenStreetMaps is a free, open source map tool much like Google or Apple maps, but is maintained by a self-governing community of volunteers where anyone is welcome to contribute. An April 27 thread in the OpenStreetMap community forum first spotted the issue, flagging two users in Italy who began marking beaches in all sorts of locations where they don't actually exist.

The OpenStreetMap user who noticed the fictitious beaches immediately connected the dots: Pokemon Go, the mega popular mobile game where players catch Pokemon and can engage in different activities depending on their geolocation, introduced different "biomes" like beach, city, forest, and mountains. Each of these have a different look, and critically, some specific Pokemon will only spawn at specific biomes. Wiglett, for example, only spawns at beaches. Some video game sites quickly noticed that Pokemon Go's beaches were appearing in real world locations like golf courses, sports fields, and other places that are not real beaches. Pokemon Go uses OpenStreetMap for its map data, and is how the game knows players are near certain points of interest.

The OpenStreetMap user created a filter of OpenStreetMap that surfaced instances where "new mappers" added beaches to the map, revealing a number of clearly fake submissions. [...] It's not clear how often Pokemon Go updates the game with data from OpenStreetMaps, but in theory the people who are manipulating the data would have easier access to the beach biome the next time it does. The OpenStreetMap thread goes on to identify one repeat offender who added dozens of fake beaches. Some are near bodies of water, like lakes, rivers, or docks, and others are landlocked schools, parking lots, and random strips of land. If there was any doubt that some of these changes are being made by Pokemon Go players, the same repeat offender also marked the map with his handle, as well as a poke ball.

"Without San Francisco, Star Wars wouldn't exist," says David Reat, the culture studies director of the architecture department at Glasgow's University of Strathclyde.

SFGate reports: Lucas was born and raised in Modesto, where his father expected him to run the family stationery store once he turned 18, but Lucas instead left for Los Angeles, where he studied film production at the University of Southern California, before moving to San Francisco. Despite all that these cities had to offer, Lucas constantly found himself conflicted over his feelings toward them. "The battle of living in the country versus living in the city is huge with Lucas," says Reat, who notes that this theme runs throughout the likes of "THX 1138," "American Graffiti" and the "Star Wars" series. "He sees cities as the givers and takers of things. He's fascinated by cities. He doesn't actually want to live in one. He now lives in a ranch near one. He wants to orbit them. He's a paradox."

When Lucas moved to San Francisco in the late 1960s, there were a number of huge building projects taking place across the city that piqued the burgeoning filmmaker's interest, most notably the construction of BART and a new terminal at San Francisco airport. "Infrastructure really fascinated Lucas. They were these big huge alienating spaces," says Reat. "I think Lucas was driving around San Francisco, looking at them, and seeing that they looked alien." There's a reason why Lucas was particularly interested in the architecture in San Francisco: "He's on record as saying he wanted to be an architect," says Reat. "He has referred to himself as a frustrated architect." Lucas' interest provoked him and his creative team to put extra care and thought into each of the "Star Wars" buildings, vehicles, houses, villages, cities, worlds and galaxies, especially when it came to what they symbolized and represented.

"The architecture in the films play a key role for younger viewers," says Reat, explaining that it helps to indicate who is good and who is evil. When it comes to the Death Star there are "no women, no plants, no signs of life, and it's basically the Nazis in space," continues Reat. "Lucas doesn't like modernism. He always uses it for bad things, a bit like every James Bond baddie." Meanwhile, Luke Skywalker and the rest of the light side of the Force are seen living in "exaggerated domesticity" as they sit around drinking blue milk, surrounded by creatures. "There's a care and a weirdness to their architecture, plus it's loaded with color," says Reat, who adds that these choices help to make those characters more appealing and relatable....

The San Francisco International Airport also played a key role in the making of "Phantom Menace." A tour of its maintenance bay gave the film's creative designers a jolt of inspiration when they were creating Anakin's podracer and other vehicles.
The article also adds that the inspiration for the Theed Royal Palace on Naboo in The Phantom Menace was "the Marin County Civic Center, where Lucas once served jury duty."

An international team of scientists used 1.8 billion letters of genetic code from more than 9,500 species covering almost 8,000 known flowering plant genera to create the most up-to-date understanding of the flowering plant tree of life. The research has been published in the journal Nature. Phys.Org reports: The major milestone for plant science, led by [Royal Botanic Gardens, Kew] and involving 138 organizations internationally, was built on 15 times more data than any comparable studies of the flowering plant tree of life. Among the species sequenced for this study, more than 800 have never had their DNA sequenced before. The sheer amount of data unlocked by this research, which would take a single computer 18 years to process, is a huge stride towards building a tree of life for all 330,000 known species of flowering plants -- a massive undertaking by Kew's Tree of Life Initiative.

The flowering plant tree of life, much like our own family tree, enables us to understand how different species are related to each other. The tree of life is uncovered by comparing DNA sequences between different species to identify changes (mutations) that accumulate over time like a molecular fossil record. Our understanding of the tree of life is improving rapidly in tandem with advances in DNA sequencing technology. For this study, new genomic techniques were developed to magnetically capture hundreds of genes and hundreds of thousands of letters of genetic code from every sample, orders of magnitude more than earlier methods. A key advantage of the team's approach is that it enables a wide diversity of plant material, old and new, to be sequenced, even when the DNA is badly damaged. The vast treasure troves of dried plant material in the world's herbarium collections, which comprise nearly 400 million scientific specimens of plants, can now be studied genetically.

[...] Across all 9,506 species sequenced, more than 3,400 came from material sourced from 163 herbaria in 48 countries. Additional material from plant collections around the world (e.g., DNA banks, seeds, living collections) have been vital for filling key knowledge gaps to shed new light on the history of flowering plant evolution. The team also benefited from publicly available data for more than 1,900 species, highlighting value of the open science approach to future genomic research. Flowering plants alone account for about 90% of all known plant life on land and are found virtually everywhere on the planet -- from the steamiest tropics to the rocky outcrops of the Antarctic Peninsula. [...] Utilizing 200 fossils, the authors scaled their tree of life to time, revealing how flowering plants evolved across geological time. They found that early flowering plants did indeed explode in diversity, giving rise to more than 80% of the major lineages that exist today shortly after their origin. However, this trend then declined to a steadier rate for the next 100 million years until another surge in diversification about 40 million years ago, coinciding with a global decline in temperatures. These new insights would have fascinated Darwin and will surely help today's scientists grappling with the challenges of understanding how and why species diversify. A list of "remarkable species" included in the flowering plant tree of life is embedded below the article.

Looking ahead, the study's authors believe this data will aid future attempts to identify new species, refine plant classification, uncover new medicinal compounds, and conserve plants in the face of climate change and biodiversity loss.

Several "high-profile astronomers" will meet at London's Royal Society (the UK's national academy of sciences), "to question some of the most fundamental aspects of our understanding of the universe.reports Futurism: As The Guardian reports, the luminaries of cosmology will be re-examining some basic assumptions about the universe — right down to the over-a-century-old theory that it's expanding at a constant rate. "We are, in cosmology, using a model that was first formulated in 1922," coorganizer and Oxford cosmologist Subir Sarkar told the newspaper, in an apparent reference to the year Russian astronomer Alexander Friedmann outlined the possibility of cosmic expansion based on Einstein's general theory of relativity. "We have great data, but the theoretical basis is past its sell-by date," he added. "More and more people are saying the same thing and these are respected astronomers."

A number of researchers have found evidence that the universe may be expanding more quickly in some areas compared to others, raising the tantalizing possibility that megastructures could be influencing the universe's growth in significant ways. Sarkar and his colleagues, for instance, are suggesting that the universe is "lopsided" after studying over a million quasars, which are the active nuclei of galaxies where gas and dust are being gobbled up by a supermassive black hole.
The article notes that another theory is that the so-called cosmological constant that's been used for decades "actually varies across space."

AltStore PAL has become one of the first alternative app marketplaces to launch in the European Union. Developed by Riley Testut, AltStore PAL is marketed as an open-source project designed to distribute apps from independent developers. MacRumors reports: At launch, it features two apps, including Testut's Delta game emulator and clipboard manager app Clip. Delta is also being simultaneously released in the App Store outside of the European Union, but it looks like EU customers will need to download it from AltStore. Testut says that once AltStore PAL is "running smoothly," third-party app developers will be able to submit their apps for distribution outside of the App Store. The app marketplace is designed to be decentralized with no directory, so developers will need to self-promote their apps and direct users to their websites to install an app through AltStore.

Distributing apps through AltStore is free of charge, but it is worth noting that apps that see more than one million first annual installs will need to pay Apple an 0.50 euro Core Technology Fee. App marketplaces have to pay the fee for every install with no free allowance, so AltStore is charged 0.50 euros each time it is installed. To afford the fee, Testut is charging 1.50 euros per year for AltStore PAL access. Testut has been working on AltStore PAL since Apple announced plans to support alternative app marketplaces in iOS 17.4. It is open to all apps, but Testut says that it makes the most sense for "smaller, indie apps that otherwise couldn't exist due to App Store rules." AltStore PAL is equipped with Patreon integration to allow developers to monetize their apps. Developers can offer their apps to just their patrons, and this method of distribution also allows for a sub-1 million cap on those who can subscribe to use an app.

"Federal regulators are investigating a whistleblower's claims about flaws in the assembly of Boeing's 787 Dreamliner," NPR reported this week: Longtime Boeing engineer Sam Salehpour went public Tuesday with claims that he observed problems with how parts of the plane's fuselage were fastened together. Salehpour warns that production "shortcuts" could significantly shorten the lifespan of the plane, eventually causing the fuselage to fall apart in mid-flight. "It can cause a catastrophic failure," Salehpour said Tuesday during a press briefing to discuss his claims.

A spokesman for the FAA confirmed that the agency is investigating those allegations, which were first reported by the New York Times, but declined to comment further on them. Boeing immediately pushed back. "These claims about the structural integrity of the 787 are inaccurate and do not represent the comprehensive work Boeing has done to ensure the quality and long-term safety of the aircraft," Boeing spokeswoman Jessica Kowal said in a statement. "We are fully confident in the 787 Dreamliner."
Salehpour and his lawyers argue that Boeing has never adequately addressed production flaws discovered in 2021 (which included unacceptable gaps between the fuselage panels), according to the article. "Instead, he says the company took 'shortcuts' by applying greater force to fit segments of the fuselage together." "Boeing hid the problem by pushing the pieces together with force to make it appear like that the gap didn't exist," Salehpour told reporters at Tuesday's press briefing. Salehpour says he repeatedly raised these concerns with management, but instead of addressing them, they transferred him to work on a different plane, the 777, where he alleges he saw similar problems. "I literally saw people jumping on the pieces of the airplane to get them to align," he said. "That's not how you build a plane."
In a follow-up piece, NPR reports that former Boeing mechanic Davin Fischer "says he spoke up — and paid a steep price for it." He says Boeing's leaders were constantly pushing to speed up production. "Hey, we need to go faster, faster, faster," Fischer said. "They cared more about shareholders and investors than they did planes, their employees, anything." When Fischer finally pushed back, he says he was demoted in retaliation, and then fired from the company in 2019. Fischer says many of his friends who still work at Boeing are afraid to speak out. "People there are scared, a hundred percent," he said. "Because they don't want to get fired."
NPR also cites the example of longtime quality manager John Barnett, who said in a 2019 interview with Ralph Nader that his managers at Boeing retaliated against him by docking his pay and creating a hostile environment.

An anonymous reader shared this report from ScienceAlert: The Fermi Paradox is the discrepancy between the apparent high likelihood of advanced civilizations existing and the total lack of evidence that they do exist. Many solutions have been proposed for why the discrepancy exists. One of the ideas is the 'Great Filter.' The Great Filter is a hypothesized event or situation that prevents intelligent life from becoming interplanetary and interstellar and even leads to its demise....

[H]ow about the rapid development of AI?

A new paper in Acta Astronautica explores the idea that Artificial Intelligence becomes Artificial Super Intelligence (ASI) and that ASI is the Great Filter. The paper's title is "Is Artificial Intelligence the Great Filter that makes advanced technical civilizations rare in the universe?"
"Upon reaching a technological singularity, ASI systems will quickly surpass biological intelligence and evolve at a pace that completely outstrips traditional oversight mechanisms, leading to unforeseen and unintended consequences that are unlikely to be aligned with biological interests or ethics," the paper explains... The author says their projects "underscore the critical need to quickly establish regulatory frameworks for AI development on Earth and the advancement of a multiplanetary society to mitigate against such existential threats."

"The persistence of intelligent and conscious life in the universe could hinge on the timely and effective implementation of such international regulatory measures and

Late last year the messaging app Beeper raised the ire of Apple when it found a way to recreate Apple's infamous "blue bubble" messaging on Android. Apple later hobbled Beeper, but it's not an entirely unhappy ending: The startup has been acquired in a deal valued at $125 million. From a report: Founded three years ago, Beeper is being snapped up by Automattic, the respected parent company of WordPress, the blogging and content management platform, as well as Tumblr, which it acquired in 2019. Beeper cofounder Eric Migicovsky said that the company will continue to exist as a stand-alone product within Automattic, and that all of Beeper's 27 employees -- who, like Automattic's employees, are entirely remote -- will be absorbed into the larger entity.

Exact financial terms of the acquisition weren't disclosed. According to Migicovsky, Beeper will be part of Automattic's broader strategy to offer more messaging features. Automattic first invested in Beeper in 2022, and late last year snatched up another messaging app, Texts, for $50 million. The acquisition comes on the heels of a highly publicized battle between Beeper and Apple, in which Beeper tried to bridge the gap between Android messaging and iMessage but was ultimately thwarted. It was unable to monetize its app and, with 30,000 users as of writing, hadn't reached critical mass.

An anonymous reader quotes a report from 404 Media: Last week, Ernie Smith, the publisher of the website Tedium, got a "copyright infringement notice" from a law firm called Commonwealth Legal: "We're reaching out on behalf of the Intellectual Property division of a notable entity, in relation to an image connected to our client," it read. [...] In this case, though, the email didn't demand that the photo be taken down or specifically threaten a lawsuit. Instead, it demanded that Smith place a "visible and clickable link" beneath the photo in question to a website called "tech4gods" or the law firm would "take action." Smith began looking into the law firm. And he found that Commonwealth Legal is not real, and that the images of its "lawyers" are AI generated.

The threat to "activate the case No. 86342" is obviously nonsense. Beyond that, Commonwealth Legal's website looks generic and is full of stock photos, though I've seen a lot of generic template websites for real law firms. All of its lawyers have vacant, thousand-yard stares that are commonly generated by websites like This Person Does Not Exist, none of them come up in any attorney or LinkedIn searches, and the only reverse image search results for them are for a now-broken website called Generated.Photos, which offered a service to "use AI to generate people online that don't exist, change clothing and modify face and body traits. Download generated people in different postures." "All of the faces scanned were likely AI generated, most likely by a Generative Adversarial Network (GAN) model," Ali Shahriyari, cofounder and CTO of the AI detection startup Reality Defender told 404 Media. Commonwealth Legal's listed address is the fourth floor of a one-story building that looks nothing like the image on its website, and both of its phone numbers are disconnected. No one responded to the contact form that I filled out. Smith realized that what's happening here isn't a copyright enforcement or copyright trolling attempt at all. Instead, it's a backlink SEO scam, where a website owner tries to improve their Google ranking by asking, paying, or threatening someone to link to their website.

Tech4Gods.com is a gadget review website run by a man named Daniel Barczak, whose content is "complemented by AI writing assistants." In this case, the photo that Smith had "infringed" was a photo downloaded from the royalty free, free-to-use website Unsplash, which 404 Media also sometimes uses. The image was not taken by Barczak, and has nothing to do with him, he told me in an email: "I certainly don't own any images on the web," he said. The original photographer did not respond to a request for comment sent through Unsplash. Barczak told me that he had been previously buying backlinks to his website for SEO, but said he wasn't aware of who was doing this or why. "I have no idea; it certainly has nothing to do with me," he said. "However, recently, someone has been building spammy links against my site that I have been dealing with." "I have mastered on-page SEO, but unfortunately, I buy links due to a lack of time," he added. "In the past, I had a bad link builder. I wonder if it's him going mad at me for letting him go It's hard to say the web is massive, and everyone can link whenever they want." Link building is an SEO strategy devised to get outside websites to link to your website. He added that "bad links may damage [the site's] profile in Google's eyes." In this case, however, the "lawyers" were threatening a well-established tech blogger, and a link from Tedium would likely be treated as a positive in the search algorithm's eyes.

An anonymous reader shares a report: Burnout, quiet quitting, strikes -- the news (and likely your schedule) is filled with markers that workers are overwhelmed and too much is expected of them. There's little regulation in the United States to prevent employers from forcing workers to be at their desks or on call at all hours, but that might soon change. California State Assemblyman Matt Haney has introduced AB 2751, a "right to disconnect" proposition, The San Francisco Standard reports. The bill is in its early stages but, if passed, would make every California employer lay out exactly what a person's hours are and ensure they aren't required to respond to work-related communications while off the clock. Time periods in which a salaried employee might have to work longer hours would need to be laid out in their contract. Exceptions would exist for emergencies.

The Department of Labor would monitor adherence and fine companies a minimum of $100 for wrongdoing -- whether that's forcing employees to be on Zoom, their inbox, answering texts or monitoring Slack when they're not getting paid to do so. "I do think it's fitting that California, which has created many of these technologies, is also the state that introduces how we make it sustainable and update our protections for the times we live in and the world we've created," Haney told The Standard.

Zac Hall reports via 9to5Mac: In a newly published research paper (PDF), Apple's AI gurus describe a system in which Siri can do much more than try to recognize what's in an image. The best part? It thinks one of its models for doing this benchmarks better than ChatGPT 4.0. In the paper (ReALM: Reference Resolution As Language Modeling), Apple describes something that could give a large language model-enhanced voice assistant a usefulness boost. ReALM takes into account both what's on your screen and what tasks are active. [...] If it works well, that sounds like a recipe for a smarter and more useful Siri.

Apple also sounds confident in its ability to complete such a task with impressive speed. Benchmarking is compared against OpenAI's ChatGPT 3.5 and ChatGPT 4.0: "As another baseline, we run the GPT-3.5 (Brown et al., 2020; Ouyang et al., 2022) and GPT-4 (Achiam et al., 2023) variants of ChatGPT, as available on January 24, 2024, with in-context learning. As in our setup, we aim to get both variants to predict a list of entities from a set that is available. In the case of GPT-3.5, which only accepts text, our input consists of the prompt alone; however, in the case of GPT-4, which also has the ability to contextualize on images, we provide the system with a screenshot for the task of on-screen reference resolution, which we find helps substantially improve performance."

So how does Apple's model do? "We demonstrate large improvements over an existing system with similar functionality across different types of references, with our smallest model obtaining absolute gains of over 5% for on-screen references. We also benchmark against GPT-3.5 and GPT-4, with our smallest model achieving performance comparable to that of GPT-4, and our larger models substantially outperforming it." Substantially outperforming it, you say? The paper concludes in part as follows: "We show that ReaLM outperforms previous ap- proaches, and performs roughly as well as the state- of-the-art LLM today, GPT-4, despite consisting of far fewer parameters, even for onscreen references despite being purely in the textual domain. It also outperforms GPT-4 for domain-specific user utterances, thus making ReaLM an ideal choice for a practical reference resolution system that can exist on-device without compromising on performance."

Long-time Slashdot reader HanzoSpam shared an announcement from the University of California San Diego.

The school's researchers teamed with materials-science company Algenesis to show "that their plant-based polymers biodegrade — even at the microplastic level — in under seven months." "We're trying to find replacements for materials that already exist, and make sure these replacements will biodegrade at the end of their useful life instead of collecting in the environment," stated Professor of Chemistry and Biochemistry Michael Burkart, one of the paper's authors and an Algenesis co-founder. "That's not easy."

"When we first created these algae-based polymers about six years ago, our intention was always that it be completely biodegradable," said another of the paper's authors, Robert Pomeroy, who is also a professor of chemistry and biochemistry and an Algenesis co-founder. "We had plenty of data to suggest that our material was disappearing in the compost, but this is the first time we've measured it at the microparticle level...."

"This material is the first plastic demonstrated to not create microplastics as we use it," said Stephen Mayfield, a paper coauthor, School of Biological Sciences professor and co-founder of Algenesis. "This is more than just a sustainable solution for the end-of-product life cycle and our crowded landfills. This is actually plastic that is not going to make us sick."

Creating an eco-friendly alternative to petroleum-based plastics is only one part of the long road to viability. The ongoing challenge is to be able to use the new material on pre-existing manufacturing equipment that was originally built for traditional plastic, and here Algenesis is making progress. They have partnered with several companies to make products that use the plant-based polymers developed at UC San Diego, including Trelleborg for use in coated fabrics and RhinoShield for use in the production of cell phone cases.

"When we started this work, we were told it was impossible," stated Burkart. "Now we see a different reality. There's a lot of work to be done, but we want to give people hope. It is possible."

schwit1 shares a report from ScienceAlert: Sound waves fossilized in the maps of galaxies across the Universe could be interpreted as signs of a Big Bang that took place 13 billion years earlier than current models suggest. Last year, theoretical physicist Rajendra Gupta from the University of Ottawa in Canada published a rather extraordinary proposal that the Universe's currently accepted age is a trick of the light, one that masks its truly ancient state while also ridding us of the need to explain hidden forces. Gupta's latest analysis suggests oscillations from the earliest moments in time preserved in large-scale cosmic structures support his claims. "The study's findings confirm that our previous work about the age of the Universe being 26.7 billion years has allowed us to discover that the Universe does not require dark matter to exist," says Gupta. "In standard cosmology, the accelerated expansion of the Universe is said to be caused by dark energy but is in fact due to the weakening forces of nature as it expands, not due to dark energy." [...]

Current cosmological models make the reasonable assumption that certain forces governing the interactions of particles have remained constant throughout time. Gupta challenges a specific example of this 'coupling constant', asking how it might affect the spread of space over exhaustively long periods of time. It's hard enough for any novel hypothesis to survive the intense scrutiny of the scientific community. But Gupta's suggestion isn't even entirely new -- it's loosely based on an idea that was shown the door nearly a century ago. In the late 1920s, Swiss physicist Fritz Zwicky wondered if the reddened light of far distant objects was a result of lost energy, like a marathon runner exhausted by a long journey across the eons of space. His 'tired light' hypothesis was in competition with the now-accepted theory that light's red-shifted frequency is due to the cumulative expansion of space tugging at light waves like a stretched spring.

The consequences of Gupta's version of the tired light hypothesis -- what is referred to as covarying coupling constants plus tired light, or CCC+TL -- would affect the Universe expansion, doing away with mysterious pushing forces of dark energy and blaming changing interactions between known particles for the increased stretching of space. To replace existing models with CCC+TL, Gupta would need to convince cosmologists his model does a better job of explaining what we see at large. His latest paper attempts to do that by using CCC+TL to explain fluctuations in the spread of visible matter across space caused by sound waves in a newborn Universe, and the glow of ancient dawn known as the cosmic microwave background. While his analysis concludes his hybrid tired light theory can play nicely with certain features of the Universe's residual echoes of light and sound, it does so only if we also ditch the idea that dark matter is also a thing. The research has been published in The Astrophysical Journal.

An anonymous reader quotes a report from The Verge: When Nintendo sued the developers of Yuzu out of existence on March 4th, it wasn't just an attack on the leading way to play Nintendo Switch games without a Switch. It was a warning to anyone building a video game emulator. Seven developers have now stepped away from projects, are shutting them down, or have left the emulation scene entirely. Of those that remain, many are circling the wagons, getting quieter and more careful, trying not to paint targets on their backs. Four developers declined to talk to The Verge, telling me they didn't want to draw attention. One even tried to delete answers to my questions after we'd begun, suddenly scared of attracting press.

Not everyone is so afraid. Four other emulator teams tell me they're optimistic Nintendo won't challenge them, that they're on strong legal footing, and that Yuzu may have been an unusually incriminating case. One decade-long veteran tells me everyone's just a bit more worried. But when I point out that Nintendo didn't have to prove a thing in court, they all admit they don't have money for lawyers. They say they'd probably be forced to roll over, like Yuzu, if the Japanese gaming giant came knocking. "I would do what I'd have to do," the most confident of the four tells me. "I would want to fight it... but at the same time, I know we exist because we don't antagonize Nintendo."

There's a new meme where Yuzu is the mythical Hydra: cut off one head, and two more take its place. It's partly true in how multiple forks of Yuzu (and 3DS emulator Citra) sprung up shortly after their predecessors died: Suyu, Sudachi, Lemonade, and Lime are a few of the public names. But they're not giving Nintendo the middle finger: they're treating Nintendo's lawsuit like a guidebook about how not to piss off the company. In its legal complaint, Nintendo claimed Yuzu was "facilitating piracy at a colossal scale," giving users "detailed instructions" on how to "get it running with unlawful copies of Nintendo Switch games," among other things. Okay, no more guides, say the Switch emulator developers who spoke to me. They also say they're stripping out some parts of Yuzu that made it easier to play pirated games. As Ars Technica reported, a forked version called Suyu will require you to bring the firmware, title.keys, and prod.keys from your Switch before you can decrypt and play Nintendo games. Only one of those was technically required before. (Never mind that most people don't have an easily hackable first-gen Switch and would likely download these things off the net.) The developer of another fork tells me he plans to do something similar, making users "fend for yourself" by making sure the code doesn't auto-generate any keys.

Most developers I spoke to are also trying to make it clear they aren't profiting at Nintendo's expense. One who initially locked early access builds behind a donation page has stopped doing that, making them publicly available on GitHub instead. The leader of another project tells me nothing will ever be paywalled, and for now, there's "strictly no donation," either. When I ask about the Dolphin Emulator, which faced a minor challenge from Nintendo last year, I'm told it publicly exposes its tiny nonprofit budget for anyone to scrutinize. But I don't know that these steps are enough to prevent Nintendo from throwing around its weight again, particularly when it comes to emulating the Nintendo Switch, its primary moneymaker. Since Yuzu's shut down, a slew of other emulators left the scene. The include (as highlighted by The Verge):

- The Citra emulator for Nintendo 3DS is gone
- The Pizza Boy emulators for Nintendo Game Boy Advance and Game Boy Color are gone
- The Drastic emulator for Nintendo DS is free for now and will be removed
- The lead developer of Yuzu and Citra has stepped away from emulation
- The lead developer of Strato, a Switch emulator, has stepped away from emulation
- Dynarmic, used to speed up various emulators including Yuzu, has abruptly ended development
- One contributor on Ryujinx, a Switch emulator, has stepped away from the project
- AetherSX2, a PS2 emulator, is finally gone (mostly unrelated; development was suspended a year ago)

Google announced a major change to its Safe Browsing feature in Chrome today that will make the service work in real time by checking against a server-side list -- all without sharing your browsing habits with Google. From a report: Previously, Chrome downloaded a list of known sites that harbor malware, unwanted software and phishing scams once or twice per hour. Now, Chrome will move to a system that will send the URLs you are visiting to its servers and check against a rapidly updated list there. The advantage of this is that it doesn't take up to an hour to get an updated list because, as Google notes, the average malicious site doesn't exist for more than 10 minutes.

The company claims that this new server-side system can catch up to 25 percent more phishing attacks than using local lists. These local lists have also grown in size, putting more of a strain on low-end machines and low-bandwidth connections. Google is rolling out this new system to desktop and iOS users now, with Android support coming later this month.

A new startup called Cognition AI can turn a user's prompt into a website or video game. From a report: A new installment of Silicon Valley's most exciting game, Are We in a Bubble?!, has begun. This time around the game's premise hinges on whether AI technology is poised to change the world as the consumer internet did -- or even more dramatically -- or peter out and leave us with some advances but not a new global economy. This game isn't easy to play, and the available data points often prove more confusing than enlightening. Take the case of Cognition AI Inc.

You almost certainly have not heard of this startup, in part because it's been trying to keep itself secret and in part because it didn't even officially exist as a corporation until two months ago. And yet this very, very young company, whose 10-person staff has been splitting time between Airbnbs in Silicon Valley and home offices in New York, has raised $21 million from Peter Thiel's venture capital firm Founders Fund and other brand-name investors, including former Twitter executive Elad Gil. They're betting on Cognition AI's team and its main invention, which is called Devin.

Devin is a software development assistant in the vein of Copilot, which was built by GitHub, Microsoft and OpenAI, but, like, a next-level software development assistant. Instead of just offering coding suggestions and autocompleting some tasks, Devin can take on and finish an entire software project on its own. To put it to work, you give it a job -- "Create a website that maps all the Italian restaurants in Sydney," say -- and the software performs a search to find the restaurants, gets their addresses and contact information, then builds and publishes a site displaying the information. As it works, Devin shows all the tasks it's performing and finds and fixes bugs on its own as it tests the code being written. The founders of Cognition AI are Scott Wu, its chief executive officer; Steven Hao, the chief technology officer; and Walden Yan, the chief product officer. Hao was most recently one of the top engineers at Scale AI, a richly valued startup that helps train AI systems. Yan, until recently at Harvard University, requested that his status at the school be left ambiguous because he hasn't yet had the talk with his parents.

The U.S. government must move "quickly and decisively" to avert substantial national security risks stemming from artificial intelligence (AI) which could, in the worst case, cause an "extinction-level threat to the human species," says a report commissioned by the U.S. government published on Monday. Time: "Current frontier AI development poses urgent and growing risks to national security," the report, which TIME obtained ahead of its publication, says. "The rise of advanced AI and AGI [artificial general intelligence] has the potential to destabilize global security in ways reminiscent of the introduction of nuclear weapons." AGI is a hypothetical technology that could perform most tasks at or above the level of a human. Such systems do not currently exist, but the leading AI labs are working toward them and many expect AGI to arrive within the next five years or less.

The three authors of the report worked on it for more than a year, speaking with more than 200 government employees, experts, and workers at frontier AI companies -- like OpenAI, Google DeepMind, Anthropic and Meta -- as part of their research. Accounts from some of those conversations paint a disturbing picture, suggesting that many AI safety workers inside cutting-edge labs are concerned about perverse incentives driving decisionmaking by the executives who control their companies. The finished document, titled "An Action Plan to Increase the Safety and Security of Advanced AI," recommends a set of sweeping and unprecedented policy actions that, if enacted, would radically disrupt the AI industry. Congress should make it illegal, the report recommends, to train AI models using more than a certain level of computing power.

The threshold, the report recommends, should be set by a new federal AI agency, although the report suggests, as an example, that the agency could set it just above the levels of computing power used to train current cutting-edge models like OpenAI's GPT-4 and Google's Gemini. The new AI agency should require AI companies on the "frontier" of the industry to obtain government permission to train and deploy new models above a certain lower threshold, the report adds. Authorities should also "urgently" consider outlawing the publication of the "weights," or inner workings, of powerful AI models, for example under open-source licenses, with violations possibly punishable by jail time, the report says. And the government should further tighten controls on the manufacture and export of AI chips, and channel federal funding toward "alignment" research that seeks to make advanced AI safer, it recommends.
