On February 24th, the Vera C. Rubin Observatory activated its automated alert system, sending out roughly 800,000 real-time notifications flagging asteroids, supernovae, flaring black holes and "other transient celestial events," reports Scientific American. And this is only the beginning -- that number is projected to climb into the millions as it continues scanning the ever-changing sky. From the report: The astronomical observatory equipped with world's largest camera hit a key milestone on February 24, when a complex data-processing system pushed hundreds of thousands of alerts out to scientists eager to pore over its most exciting sightings. The Vera C. Rubin Observatory began operations last year, capturing stunning, panoramic time-lapse views of the cosmos with ease. Rubin's first images, based on just 10 hours of observations, let space fans zoom seemingly forever into an overwhelmingly starry sky. But watchful astronomers were always awaiting the next step: the system that would automatically alert them to the most promising activity in the overhead sky amid the 1,000 or so enormous images that Rubin's telescope captures every night.

"We can detect everything that changes, moves and appears," said Yusra AlSayyad, an astronomer at Princeton University and Rubin's deputy associate director for data management, to Scientific American last summer. "It's way too much for one person to manually sift through and filter and monitor themselves." So even as they were designing and building the Rubin Observatory itself, scientists were also designing an alert system to help astronomers navigate the flood of data. As soon as the telescope began observations, the team started constructing a static reference image of the entire sky in impeccable detail.

Now the data processing systems that support the observatory are starting to automatically compare every new Rubin image to the corresponding section of that background template. The systems identify all of the differences, each of which is individually flagged. The algorithms can also distinguish between a potential supernova and a possible newfound asteroid, for example. Alerting the scientific community is the final, crucial step. Astronomers -- as well as members of the public -- can sign up for notifications based on the type of sighting they're interested in and the brightness of the observation in question. And now that the alerts system has gone live, users receive a tiny, fuzzy image with some astronomical metadata of each observation that fits their criteria -- all just a couple of minutes after Rubin captures the original image.

For the first time, astronomers have confirmed the existence of a lone black hole," reports Science News — "one with no star orbiting it." It's "the only one so far," says Kailash Sahu, an astronomer at the Space Telescope Science Institute in Baltimore. In 2022, Sahu and his colleagues discovered the dark object coursing through the constellation Sagittarius. A second team disputed the claim, saying the body might instead be a neutron star. New observations from the Hubble Space Telescope now confirm that the object's mass is so large that it must be a black hole, Sahu's team reports in the April 20 Astrophysical Journal.... [And that second team has revised its assessment and now agrees: the object is a black hole.]

While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star's light and slowly shifting its position due to the black hole's gravity. This passage occurred in July 2011, but the star's position is still changing. "It takes a long time to do the observations," Sahu says. "Everything is improved if you have a longer baseline and more observations." The original discovery relied on precise Hubble measurements of star positions from 2011 to 2017. The new work incorporates Hubble observations from 2021 and 2022 as well as data from the Gaia spacecraft.

The upshot: The black hole is about seven times as massive as the sun, give or take 0.8 solar masses.... Located 5,000 light-years from Earth, this black hole is much closer than the supermassive one at the Milky Way's center, which also lies in Sagittarius but about 27,000 light-years from us. The star-rich region around the galactic center provides an ideal hunting ground for solitary black holes passing in front of stars. Sahu hopes to find additional lone black holes by using the Nancy Grace Roman Space Telescope, slated for launch in 2027.

An anonymous reader quotes a report from Gizmodo: Protector, an app that lets you book armed goons the same way you'd call for an Uber, is having a viral moment. The app started doing the rounds on social media after consultant Nikita Bier posted about it on X. Protector lets the user book armed guards on demand. Right now it's only available in NYC and LA. According to its marketing, every guard is either "active duty or retired law enforcement and military." Every booking comes with a motorcade and users get to select the number of Escalades that'll be joining them as well as the uniforms their hired goons will wear.

Protector is currently "#7 in Travel" on Apple's App Store. It's not available for people who use Android devices. [...] The marketing for Protector, which lives on its X account, is surreal. A series of robust and barrel-chested men in ill-fitting black suits deliver their credentials to the camera while sitting in front of a black background. They're all operators. They describe careers in SWAT teams and being deployed to war zones. They show vanity shots of themselves kitted out in operator gear. All of them have a red lapel pin bearing the symbol of Protector. If the late UnitedHealthcare CEO had used Protector, he might still be alive today, suggests Protector in its marketing materials. A video on X shows "several fantasy versions of the assassination where a Protector is on hand to prevent the assassin from killing the CEO," reports Gizmodo.

The app is a product from parent company Protector Security Solutions, which was founded by Nick Sarath, a former product designer at Meta.

Alan W. Filion, an 18-year-old from Lancaster, Calif., was sentenced to four years in prison for making nearly 400 false bomb threats and threats of violence (source may be paywalled; alternative source) to religious institutions, schools, universities and homes across the country. The New York Times reports: The threatening calls Mr. Filion made would often cause large deployments of police officers to a targeted location, the Justice Department said in a news release. In some cases, officers would enter people's homes with their weapons drawn and detain those inside. In January 2023, Mr. Filion wrote on social media that his swats had often led the police to "drag the victim and their families out of the house cuff them and search the house for dead bodies."

Investigators linked Mr. Filion to over 375 swatting calls made in several states, including one that he made to the police in Sanford, Fla., saying that he would commit a mass shooting at the Masjid Al Hayy Mosque. During the call, he played audio of gunfire in the background. Mr. Filion was arrested in California in January 2024, and was then extradited to Florida to face state charges for making that threat. Mr. Filion began swatting for recreation in August 2022 before making it into a business, the Justice Department said. The teenager became a "serial swatter" and would make social media posts about his "swatting-for-a-fee" services, according to prosecutors.

In addition to pleading guilty to the false threat against the mosque in Florida, Mr. Filion pleaded guilty in three other swatting cases: a mass shooting threat to a public school in Washington State in October 2022; a bomb threat call to a historically Black college or university in Florida in May 2023; and a July 2023 call in which he claimed to be a federal law enforcement officer in Texas and told dispatchers that he had killed his mother and would kill any responding officers.

An anonymous reader quotes a report from the European Space Agency: White dots arranged in five clusters against a black background (PNG). This is the simulated extraterrestrial signal transmitted from Mars and deciphered by a father and a daughter on Earth after a year-long decoding effort. On June 7, 2024, media artist Daniela de Paulis received this simple, retro-looking image depicting five amino acids in her inbox. It was the solution to a cosmic puzzle beamed from ESA's ExoMars Trace Gas Orbiter (TGO) in May 2023, when the European spacecraft played alien as part of the multidisciplinary art project 'A Sign in Space.' After three radio astronomy observatories on Earth intercepted the signal, the challenge was first to extract the message from the raw data of the radio signal, and secondly to decode it. In just 10 days, a community of 5000 citizen scientists gathered online and managed to extract the signal. The second task took longer and required some visionary minds.

US citizens Ken and Keli Chaffin cracked the code following their intuition and running simulations for hours and days on end. The father and daughter team discovered that the message contained movement, suggesting some sort of cellular formation and life forms. Amino acids and proteins are the building blocks of life. Now that the cryptic signal has been deciphered, the quest for meaning begins. The interpretation of the message, like any art piece, remains open. Daniela crafted the message with a small group of astronomers and computer scientists, with support from ESA, the SETI Institute and the Green Bank Observatory. The artist and collaborators behind the project are now taking a step back and witnessing how citizen scientists are shaping the challenge on their own.

"The Big Bang may not have been the beginning of the universe," writes LiveScience, citing "a theory of cosmology that suggests the universe can 'bounce' between phases of contraction and expansion."

The recent study suggests that dark matter could be composed of black holes formed before the Big Bang, during a transition from the universe's last contraction to the current expansion phase... In the new study, researchers explored a scenario where dark matter consists of primordial black holes formed from density fluctuations that occurred during the universe's last contraction phase, not long before the period of expansion that we observe now. They published their findings in June in the Journal of Cosmology and Astroparticle Physics ... In this "bouncing" cosmology, the universe contracted to a size about 50 orders of magnitude smaller than it is today. After the rebound, photons and other particles were born, marking the Big Bang. Near the rebound, the matter density was so high that small black holes formed from quantum fluctuations in the matter's density, making them viable candidates for dark matter.

"Small primordial black holes can be produced during the very early stages of the universe, and if they are not too small, their decay due to Hawking radiation [a hypothetical phenomenon of black holes emitting particles due to quantum effects] will not be efficient enough to get rid of them, so they would still be around now," Patrick Peter, director of research at the French National Centre for Scientific Research (CNRS), who was not involved in the study, told Live Science in an email. "Weighing more or less the mass of an asteroid, they could contribute to dark matter, or even solve this issue altogether."

The scientists' calculations show that this universe mode's properties, such as the curvature of space and the microwave background, match current observations, supporting their hypothesis.
"If this hypothesis holds, the gravitational waves generated during the black hole formation process might be detectable by future gravitational wave observatories, providing a way to confirm this dark matter generation scenario..."

Almost 3 years after launching the first OnePlus Watch, the Chinese smartphone company is launching a successor -- this time powered by Wear OS 4. Utilizing a "hybrid interface," the OnePlus Watch 2 is able to offer 100 hours of battery life, or just over four full days of use. 9to5Google reports: To achieve that goal, the OnePlus Watch 2 actually runs two separate operating systems. Wear OS handles things like apps and watchfaces, while a RTOS powered by a secondary chipset handles more lightweight tasks. A "smart mode" on the watch allows the watch swap back and forth between its two operating systems and two chipsets. Wear OS is powered by the Snapdragon W5 Gen 1 and it is Wear OS 4. The RTOS is powered by a BES 2700 MCU Efficiency chipset.

Switching between the two OS's is something you're likely to not even notice, OnePlus claims: "The BES2700 Efficiency Chipset runs RTOS and handles background activity and simple tasks, while the Snapdragon W5 handles more demanding tasks, like running your favorite Google apps. This optimized approach, enabled by the Wear OS hybrid interface seamlessly managing the transition between chips, means users will experience a smartwatch that effortlessly does it all while extending the time between charges."

Powering the Watch 2 is a 500 mAh battery which features 7.5W charging with a special charger that connects to a typical USB-C cable. The charger is magnetic, of course, and OnePlus claims a full charge in 60 minutes or less. The 1.43-inch AMOLED display of the OnePlus Watch 2 is covered in a slightly curved sapphire glass, while the watch chassis is built from stainless steel. You'll have the choice of black or silver colors with either black or green bands, respectively. The whole package is also 5ATM water resistant. Rounding out the main specs you'll find 32GB of storage and 2GB of RAM. The OnePlus Watch 2 goes on sale today at $299.

Amazon-owned Wickr is dead, more than a year after reports showed it had become the app of choice for drug traffickers. 404 Media: If you open the encrypted messaging app Wickr Me today, you'll be greeted with a line of red text: "Reconnecting..." Below that, in white text over a black background, the app says "We're having issues connecting to the Wickr Me network. If the problem persists, try restarting your app or contacting support." Closing and reopening the app will not work. There is no point in contacting support either. That's because on December 31, 2023, Wickr Me, the free version of Wickr, was shut down entirely.

Wickr Me is no longer available to download on the Apple App Store or the Google Play Store. The app stopped accepting new users more than a year ago. And now, even current users cannot speak to one another. So ends the story of an app that while never reaching the popularity of other encrypted messaging apps like Signal, nor those that later turned on end-to-end encryption for the masses like WhatsApp, nonetheless played an important role in the adoption of and debate around secure communications.

An anonymous reader quotes a report from Ars Technica: Modern fighting games have come quite a long way from their origins in providing accessibility options. Street Fighter 6 has audio cues that can convey distance, height, health, and other crucial data to visually impaired players. King of Fighters 15 allows for setting the contrast levels between player characters and background. Competitors like BrolyLegs and numerous hardware hackers have taken the seemingly inhospitable genre even further. Tekken 8, due later this month, seems to aim even higher, offering a number of color vision options in its settings. This includes an unofficially monikered "colorblind mode," with black-and-white and detail-diminished backgrounds and characters' flattened shapes filled in with either horizontal or vertical striped lines. But what started out as excitement in the fighting game and accessibility communities about this offering has shifted into warnings about the potential for migraines, vertigo, or even seizures.

You can see the mode in action in the Windows demo or in a YouTube video shared by Gatterall -- which, of course, you should not view if you believe yourself susceptible to issues with strobing images. Gatterall's enthusiasm for Tekken 8's take on colorblind accessibility ("Literally no game has done this") drew comment from Katsuhiro Harada, head of the Tekken games for developer and publisher Bandai Namco, on X (formerly Twitter). Harada stated that he had developed and tested "an accessibility version" of Tekken 7, which was never shipped or sold. Harada states that those "studies" made it into Tekken 8.

Not everybody in game accessibility circles was excited to see the new offerings, especially when it was shared directly with them by excited followers. Morgan Baker, game-accessibility lead at Electronic Arts, asked followers to "Please stop tagging me in the Tekken 8 'colorblind' stripe filters." The scenes had "already induced an aura migraine," Baker wrote, and she could not "afford to get another one right now." Accessibility consultant Ian Hamilton reposted a number of people citing migraines, nausea, or seizure concerns while also decrying the general nature of colorblind "filters" as an engineering-based approach to a broader design challenge. He added in the thread that shipping a game that contained a potentially seizure-inducing mode could result in people inadvertently discovering their susceptibility, similar to an infamous 1997 episode of the Pokemon TV series. Baker and Hamilton also noted problems with such videos automatically playing on sites like X/Twitter. "Patterns of lines moving on a screen creates a contiguous area of high-frequency flashing, like an invisible strobe," explained James Berg, accessibility project manager at Xbox Game Studios. "Human meat-motors aren't big fans of that." People typically start to notice "flicker fusion frequency" at around 40 frames per second, notes Ars.

Tekken's Harada responded by saying a "very few" number of people misunderstood what his team was trying to do with this mode. There are multiple options, not just one colorblind mode, Harada wrote, along with brightness adjustments for effects and other elements.

"These color vision options are a rare part of the fighting game genre, but they are still being researched and we intend to expand on them in the future," Harada wrote. Developers "have been working with several research institutes and communities to develop this option," even before the unsold "accessibility version of Tekken 7," added Harada.

Wikipedia defines LIGO as "a large-scale physics experiment and observatory designed to detect cosmic gravitational waves." (It stands for Laser Interferometer Gravitational-Wave Observatory — that is, measuring the interference caused by superimposed waves.)

Now Science Alert reports: A technique for squeezing light in the arms of LIGO's interferometer has allowed its measurements to cross the quantum barrier.

For LIGO, it's a bold new realm of sensitivity, giving the gravitational wave detector the ability to find 60% more dead star mergers than the rate of its previous run, which was around one or two detections every week or so... "Now that we have surpassed this quantum limit, we can do a lot more astronomy," says physicist Lee McCuller of Caltech...

LIGO's sensitivity was already absolutely jaw-dropping. The interferometer works by detecting ripples in space-time that are generated by colliding black holes and neutron stars, millions of billions to light-years away. These cause gravitational waves, like ripples in a pond. We can't feel them; but they can be detected in miniscule deviations in the path of light down a long, long tunnel. These deviations are incredibly small, down to trillions of times smaller than a human hair. But once you get into subatomic scales — the quantum realm — LIGO's abilities are hobbled. That's because, on those unimaginably small scales, particles randomly pop in and out of space, creating a constant background hiss of quantum noise that's louder than any signal.

Frequency-dependent squeezing is a way of amplifying the signals to be 'louder' than the quantum noise... If you pinch a property of light, such as amplitude (or power), other properties, such as frequency, can be measured more accurately... [T]he light can be squeezed in multiple ways to amplify the frequency of the gravitational waves the scientists are looking for... "We've known for a while how to write down the equations to make this work, but it was not clear that we could actually make it work until now. It's like science fiction," says physicist Rana Adhikari of Caltech...

This means we're likely to see a significant uptick in the number of black hole and neutron star collisions we observe out there in the wider Universe.

"Earlier this year, after 15 years of searching, scientists finally heard the background hum of low-frequency gravitational waves that fill our universe," writes Space.com.

"Now, the hard work of searching for the source of these ripples in spacetime can begin." Currently, the primary suspects in this case are pairings of supermassive black holes with masses millions, or even billions, of times that of the sun. However, that doesn't mean that there isn't room for a few unusual suspects, which could potentially point us toward new physics....

[G]ravitational waves detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO) express wavelengths that are thousands of miles (or km) in length and hold frequencies of milliseconds to seconds. The new gravitational waves detected by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), by contrast, have wavelengths on a scale of trillions of miles (or km). This is similar to the distance between the sun and its neighboring star, Proxima Centauri, a staggering 20 light-years in length. Plus, NANOGrav gravitational wavelengths have frequencies on scales of years instead of mere seconds. Practically, what this means is scientists need to build over 15 years of NANOGrav data to confirm a low-frequency gravitational wave detection.

But, when it happens, it's worth the wait. That's because these results have the capacity to point us toward new information about our universe... "The detection of low-frequency gravitational waves means they're from very different sources to the LIGO and Virgo sources, which are stellar mass black holes and neutron star mergers," Scott Ransom, a National Radio Astronomy Observatory astronomer and former chair of NANOGrav, told Space.com... Ransom is part of a collaboration of researchers that believe low-frequency gravitational waves, including those detected by NANOGrav, may originate from a pretty incredible source. They could come from, the team argues, hundreds of thousands of supermassive black hole pairings that, over the 13.8-billion-year course of cosmic history, came close enough together that they've merged...

"For many decades, theorists have hypothesized that supermassive black hole binaries should produce a signal with characteristics just like what NANOGrav and other pulsar timing arrays are seeing," Luke Zoltan Kelly, a Northwestern University theoretical astrophysicist and NANOGrav researcher, told Space.com. "For most of the community, supermassive black hole binaries are a natural best guess for what's producing the gravitational wave background...." Zoltan Kelley pointed out to Space.com that besides binaries, there are a number of new models in cosmology and in particle physics that, under the right circumstances, could also produce a similar gravitational wave background to that detected by NANOGrav. For example, axion or 'fuzzy' dark matter, cosmic strings, inflationary phase transitions, and many others," the Northwestern astrophysicist said.

"What's really exciting about these possibilities is that each of these models is an attempt to explain some of the biggest current mysteries of our universe."

An anonymous reader quotes a report from The Verge: During today's press conference in which Hollywood actors confirmed that they were going on strike, Duncan Crabtree-Ireland, SAG-AFTRA's chief negotiator, revealed a proposal from Hollywood studios that sounds ripped right out of a Black Mirror episode. In a statement about the strike, the Alliance of Motion Picture and Television Producers (AMPTP) said that its proposal included "a groundbreaking AI proposal that protects actors' digital likenesses for SAG-AFTRA members."

When asked about the proposal during the press conference, Crabtree-Ireland said that "This 'groundbreaking' AI proposal that they gave us yesterday, they proposed that our background performers should be able to be scanned, get one day's pay, and their companies should own that scan, their image, their likeness and should be able to use it for the rest of eternity on any project they want, with no consent and no compensation. So if you think that's a groundbreaking proposal, I suggest you think again."

The use of generative AI has been one of the major sticking points in negotiations between the two sides (it's also a major issue behind the writers strike), and in her opening statement of the press conference, SAG-AFTRA president Fran Drescher said that "If we don't stand tall right now, we are all going to be in trouble, we are all going to be in jeopardy of being replaced by machines." The SAG-AFTRA strike will officially commence at midnight tonight.

An anonymous reader quotes a report from NewScientist: Netflix researchers have created a new type of AI-powered green-screen technology that can produce realistic visual effects for film and television in real time. Green-screen technology is routinely used to capture footage of actors that can then be inserted in the foreground of virtual or prerecorded scenes. To do this, actors are filmed against a bright green background, which is easily isolated and removed digitally. This process can be done automatically with reasonable accuracy, such as in television weather forecasts, but it can be thrown by items of green clothing or by transparent or fine objects, like wisps of hair. When greater accuracy is needed in films or television series, specialist operators tweak settings manually, sometimes requiring hours to perfect a shot.

In a bid to create a technique that is both fast and accurate, Netflix has come up with a method it calls Magenta Green Screen (MGS). Actors are filmed against a background of bright green LEDs while being lit from the front with red and blue ones, which together create a magenta glow (see video, [here]). Because digital cameras work by taking an individual red, green and blue value for each pixel, this technique has the effect of creating a green channel that records only the background, with the foreground appearing black, and red and blue channels that record only the foreground, leaving the background looking black. Together these create the magenta and green look. Film editors can replace the green channel in real time, realistically and instantly placing the actors in the foreground of another scene, with even potentially tricky areas, such as transparent bottles or the area around strands of hair, working without problems.

But there is a problem with the method. Because the foreground is only recorded in blue and red, it leaves the actors looking magenta-tinted. To solve this, Netflix uses artificial intelligence to put the full range of color back into the foreground, using a photograph of the actors lit normally as a reference to create a realistic-looking green channel. This AI works quickly, but not yet in real time, although fast techniques such as averaging the red and blue channels to create an approximation of a green channel work effectively enough for the director to monitor while filming.

Supermassive black holes all over the universe are merging, a fate that will eventually come for the black hole at the center of our galaxy. From a report: These mysterious cosmic structures at the heart of nearly every galaxy consume light and matter and are impossible to glimpse with traditional telescopes. But now, for the first time, astrophysicists have gathered knowledge directly from these titans, in the form of gravitational waves that ripple through space and time. What they learned suggests that the population of massive black hole pairs that are merging numbers in the hundreds of thousands -- perhaps even millions.

The gravitational waves from these mergers are all contributing to an underlying background hum of the universe that researchers can detect from Earth. The findings, from a collaboration of more than 100 scientists, help confirm what will one day happen to the supermassive black hole at our galaxy's center, known as Sagittarius A*, as it crashes into the black hole at the heart of the Andromeda galaxy. "The Milky Way galaxy is on a collision course with the Andromeda galaxy, and in about 4.5 billion years, the two galaxies are set to merge," said Joseph Simon, a University of Colorado, Boulder, astrophysicist and a member of the North American Nanohertz Observatory for Gravitational Waves, or Nanograv, which helped lead the new work with support from the National Science Foundation.

That merger, he said, will eventually result in the black hole at the center of Andromeda and Sagittarius A* sinking into the center of the newly combined galaxy and forming what is known as a binary system. The results were announced in a series of papers published Wednesday in the Astrophysical Journal Letters. "Before now, we didn't even know if supermassive black holes merged, and now we have evidence that hundreds of thousands of them are merging," said Chiara Mingarelli, a Yale University astrophysicist and a member of Nanograv. The new work could answer questions such as how these black holes grow, and how often their host galaxies merge, the researchers said.

"Multiple lines of Android devices came with preinstalled malware," reports Ars Technica, "that couldn't be removed without users taking heroic measures."

Their article cites two reports released Thursday — one from Trend Micro and one from TechCrunch: Trend Micro researchers following up on a presentation delivered at the Black Hat security conference in Singapore reported that as many as 8.9 million phones comprising as many as 50 different brands were infected with malware... ["It's highly likely that more devices have been preinfected," the report clarified, "but have not exchanged communication with the Command & Control server, have not been used or activated by the threat actor, or have yet to be distributed to the targeted country or market... The threat actor has spread this malware over the last five years. "]

"Guerrilla" opens a backdoor that causes infected devices to regularly communicate with a remote command-and-control server to check if there are any new malicious updates for them to install. These malicious updates collect data about the users that the threat actor, which Trend Micro calls the Lemon Group, can sell to advertisers. Guerrilla then surreptitiously installs aggressive ad platforms that can deplete battery reserves and degrade the user experience... Guerrilla is a massive platform with nearly a dozen plugins that can hijack users' WhatsApp sessions to send unwanted messages, establish a reverse proxy from an infected phone to use the network resources of the affected mobile device, and inject ads into legitimate apps...

TechCrunch detailed several lines of Android-based TV boxes sold through Amazon that are laced with malware. The TV boxes, reported to be T95 models with an h616, report to a command-and-control server that, just like the Guerrilla servers, can install any application the malware creators want. The default malware preinstalled on the boxes is known as a clickbot. It generates advertising revenue by surreptitiously tapping on ads in the background...

Android devices that come with malware straight out of the factory box are, unfortunately, nothing new. Ars has reported on such incidents at least five times in recent years (here, here, here, here, and here). All the affected models were in the budget tier.

People in the market for an Android phone should steer toward known brands like Samsung, Asus, or OnePlus, which generally have much more reliable quality assurance controls on their inventory. To date, there have never been reports of higher-end Android devices coming with malware preinstalled. There are similarly no such reports for iPhones.

An anonymous reader quotes a report from Ars Technica: Google is clawing its way back into wearable relevance. Today the company took the wraps off what is officially its first self-branded smartwatch: the Pixel Watch. Google started revamping its wearable platform, Wear OS, in partnership with Samsung. While Wear OS 3, the new version of Google's wearable platform, technically launched with the Galaxy Watch 4 last year, this is the first time we'll be seeing an unskinned version on a real device. First up: prices. Google is asking a lot here, with the Wi-Fi model going for $349 and the LTE version clocking in at $399. The Galaxy Watch 4, which has a better SoC, and the Apple Watch SE, which has a way, way better SoC, both start at $250. Google is creating an uphill battle for itself with this pricing.

Google and Samsung's partnership means the Pixel Watch is running a Samsung Exynos 9110 SoC, with a cheap Cortex M33 co-processor tacked on for low-power watch face updates and 24/7 stat tracking. This SoC is a 10 nm chip with two Cortex A53 cores and an Arm Mali T720 MP1 GPU. If you can't tell from those specs, this is a chip from 2018 that was first used in the original Samsung Galaxy Watch. For whatever reason, Google couldn't get Samsung's new chip from the Galaxy Watch 4, an Exynos W920 (a big upgrade at 5 nm, dual Cortex A55s, and a Mali-G68 MP2 GPU). It's hard to understand why this is so expensive.

The display is a fully circular 1.6-inch OLED with a density of 320 ppi (that should mean around 360 pixels across). The only size available is 41 mm, the cover is Gorilla Glass 5, and the body is stainless steel in silver, black, or gold. It has 2GB of RAM, 32GB of eMMC storage, NFC, GPS, only 2.4 GHz Wi-Fi 802.11n support (Wi-Fi 4), and a 294 mAh battery. For sensors, you get SPO2 blood oxygen, heart rate, and an ECG sensor. It's water-resistant to 5 ATM, which means you're good for submersion, hand washing, and most normal water exposure. Usually 10 ATM is preferred for serious sports swimming, but the Apple Watch is 5 ATM, and Apple does all sorts of swimming promos. Google's black UI background does a good job of hiding exactly how large the display is in relation to the body, but a few screenshots reveal just how big the bezels are around this thing. They are big. Real big. Like, hard-to-imagine-we're-still-doing-this-in-2022 big. Other things to note: the watch bands are proprietary, it'll be able to charge to 50 percent in 30 minutes, will work with any Android phone running version 8.0 and newer, and features Fitbit integration.

"Unlike the Pixel 7, which is expanding to 17 markets, the Pixel Watch is only for sale in eight countries: the US, Canada, UK, Germany, France, Australia, Japan, and Taiwan," adds Ars. "The watch is up for preorder today and ships October 13."

The NOEMA radio telescope, located on the Plateau de Bure in the French Alps, is now equipped with twelve antennas, making it the most powerful radio telescope of its kind in the northern hemisphere. Phys.Org reports: Eight years after the inauguration of the first NOEMA antenna in 2014, the large-scale European project is now complete. Thanks to its twelve 15-meter antennas, which can be moved back and forth on a specially developed rail system up to a distance of 1.7 kilometers long, NOEMA is a unique instrument for astronomical research. The telescope is equipped with highly sensitive receiving systems that operate close at the quantum limit. During observations, the observatory's twelve antennas act as a single telescope -- a technique called interferometry. After all the antennas have been pointed towards one and the same region of space, the signals they receive are combined with the help of a supercomputer. Their detailed resolution then corresponds to that of a huge telescope whose diameter is equal to the distance between the outermost antennas.

The respective arrangement of the antennas can extend over distances from a few hundred meters to 1.7 kilometers. The network thus functions like a camera with a variable lens. The further apart the antennas are, the more powerful is the zoom: the maximum spatial resolution of NOEMA is so high that it would be able to detect a mobile phone at a distance of over 500 kilometers. NOEMA is one of the few radio observatories worldwide that can simultaneously detect and measure a large number of signatures -- i.e., "fingerprints" of molecules and atoms. Thanks to these so-called multi-line observations, combined with high sensitivity, NOEMA is a unique instrument for investigating the complexity of cold matter in interstellar space as well as the building blocks of the university. With NOEMA, over 5,000 researchers from all over the world study the composition and dynamics of galaxies as well as the birth and death of stars, comets in our solar system or the environment of black holes. The observatory captures light from cosmic objects that has traveled to Earth for more than 13 billion years. NOEMA has "observed the most distant known galaxy, which formed shortly after the Big Bang," notes the report. It also "measured the temperature of the cosmic background radiation at a very early stage of the universe, a scientific first that should make it possible to trace the effects of dark energy driving the universe apart."

German Orizaola and Pablo Burraco write via The Conversation: Our work in Chernobyl started in 2016. That year, close to the damaged nuclear reactor, we detected several Eastern tree frogs (Hyla orientalis) with an unusual black tint. The species normally has a bright green dorsal coloration, although occasional darker individuals can be found. Melanin is responsible for the dark color of many organisms. What is less known is that this class of pigments can also reduce the negative effects of ultraviolet radiation. And its protective role can extend to ionizing radiation too, as it has been shown with fungi. Melanin absorbs and dissipates part of the radiation energy. In addition, it can scavenge and neutralize ionized molecules inside the cell, such as reactive oxygen species. These actions make it less likely that individuals exposed to radiation will go on to suffer cell damage and increase their survival chances.

After detecting the first black frogs in 2016, we decided to study the role of melanin colouration in Chernobyl wildlife. Between 2017 and 2019 we examined in detail the colouration of Eastern tree frogs in different areas of northern Ukraine. During those three years we analysed the dorsal skin colouration of more than 200 male frogs captured in 12 different breeding ponds. These localities were distributed along a wide gradient of radioactive contamination. They included some of the most radioactive areas on the planet, but also four sites outside the Chernobyl Exclusion Zone and with background radiation levels used as controls. Our work reveals that Chernobyl tree frogs have a much darker colouration than frogs captured in control areas outside the zone. As we found out in 2016, some are pitch-black. This colouration is not related to the levels of radiation that frogs experience today and that we can measure in all individuals. The dark colouration is typical of frogs from within or near the most contaminated areas at the time of the accident.

The results of our study suggest that Chernobyl frogs could have undergone a process of rapid evolution in response to radiation. In this scenario, those frogs with darker colouration at the time of the accident, which normally represent a minority in their populations, would have been favoured by the protective action of melanin. The dark frogs would have survived the radiation better and reproduced more successfully. More than ten generations of frogs have passed since the accident and a classic, although very fast, process of natural selection may explain why these dark frogs are now the dominant type for the species within the Chernobyl Exclusion Zone.

An anonymous reader quotes a report from Motherboard: Ukraine's airspace has been busy this year -- that's the nature of war. But scientists in the country are looking to the skies and seeing something they didn't expect: An inordinate number of UFOs, according to a new preprint paper published (PDF) by Kyiv's Main Astronomical Observatory in coordination with the country's National Academy of Science. The paper does not specifically address the war, but in the United States, the Pentagon has long hinted, speculated, and warned that some UFOs could be advanced technology from foreign militaries, specifically China and Russia (though it hasn't really given any evidence this is actually the case). The Ukraine paper is particularly notable because it not only shows that science has continued to occur during the war, but also explains that there have been a lot of sightings. "We see them everywhere," the research said. "We observe a significant number of objects whose nature is not clear."

The paper is titled Unidentified aerial phenomena I. Observations of events come from observations made at NAS' Main Astronomical Observatory in Kyiv and a village south of Kyiv called Vinarivka. According to the paper's authors, the observatories took on the job of hunting for UFO's as an independent project because of the enthusiasm around the subject. It describes a specific type of UFO the researchers call "phantoms" that is an "object [that] is a completely black body that does not emit and absorbs all the radiation falling on it." The researchers also observed that the UFOs it's seeing are so fast that it's hard to take pictures of them. "The eye does not fix phenomena lasting less than one-tenth of a second," the paper said. "It takes four-tenths of a second to recognize an event. Ordinary photo and video recordings will also not capture the [unidentified aerial phenomenon]. To detect UAP, you need to fine-tune the equipment: shutter speed, frame rate, and dynamic range."

So the researchers did just that using two meteor monitoring stations in Kyiv and Vinarivka. "We have developed a special observation technique, taking into account the high speeds of the observed objects," the paper said. "The exposure time was chosen so that the image of the object did not shift significantly during exposure. The frame rate was chosen to take into account the speed of the object and the field of view of the camera. In practice, the exposure time was less than 1 ms, and the frame rate was no less than 50 Hz." The scientists divided the phenomenon they observed into two different categories: cosmics and phantoms. "We note that Cosmics are luminous objects, brighter than the background of the sky. We call these ships names of birds (swift, falcon, eagle)," the paper said. "Phantoms are dark objects, with contrast from several to about 50 percent."

Using the cameras, stationed roughly 75 miles apart, allowed the scientists to make repeated observations of strange objects moving in the sky. The paper didn't speculate on what the objects were, merely noted the observations and mentioned the objects' incredible speeds. "Flights of single, group and squadrons of the ships were detected, moving at speeds from 3 to 15 degrees per second," the research said. "Phantoms are observed in the troposphere at distances up to 10 -- 12 km. We estimate their size from 3 to 12 meters and speeds up to 15 km/s." The easy explanation would be that these are missiles, or rockets, or something else associated with the war. But the scientists insist that their nature "is not clear."

Patrick Wardle, founder of the Objective-See Foundation, a nonprofit that creates open-source security tools for macOS, has had his code make its way into a number of commercial products over the years -- "all without the users crediting him or licensing and paying for the work," reports The Verge. Wardle, a Mac malware specialist and former employee of the NSA and NASA, will lay out his case in a presentation today at the Black Hat cybersecurity conference with Tom McGuire, a cybersecurity researcher at Johns Hopkins University. From the report: The problem, Wardle says, is that it's difficult to prove that the code was stolen rather than implemented in a similar way by coincidence. Fortunately, because of Wardle's skill in reverse-engineering software, he was able to make more progress than most. "I was only able to figure [the code theft] out because I both write tools and reverse engineer software, which is not super common," Wardle told The Verge in a call before the talk. "Because I straddle both of these disciplines I could find it happening to my tools, but other indie developers might not be able to, which is the concern."

One of the central examples in Wardle's case is a software tool called OverSight, which Wardle released in 2016. Oversight was developed as a way to monitor whether any macOS applications were surreptitiously accessing the microphone or webcam, with much success: it was effective not only as a way to find Mac malware that was surveilling users but also to uncover the fact that a legitimate application like Shazam was always listening in the background. [...] But years after Oversight was released, he was surprised to find a number of commercial applications incorporating similar application logic in their own products -- even down to replicating the same bugs that Wardle's code had.

Three different companies were found to be incorporating techniques lifted from Wardle's work in their own commercially sold software. None of the offending companies are named in the Black Hat talk, as Wardle says that he believes the code theft was likely the work of an individual employee, rather than a top-down strategy. The companies also reacted positively when confronted about it, Wardle says: all three vendors he approached reportedly acknowledged that his code had been used in their products without authorization, and all eventually paid him directly or donated money to the Objective-See Foundation. The Verge notes that Wardle's cousin Josh Wardle created the popular Wordle game, which was purchased earlier this year by The New York Times.
