Clancy William James writes via The Conversation: We have just published evidence in Nature Astronomy for what might be producing mysterious bursts of radio waves coming from distant galaxies, known as fast radio bursts or FRBs. Two colliding neutron stars -- each the super-dense core of an exploded star -- produced a burst of gravitational waves when they merged into a "supramassive" neutron star. We found that two and a half hours later they produced an FRB when the neutron star collapsed into a black hole. Or so we think. The key piece of evidence that would confirm or refute our theory -- an optical or gamma-ray flash coming from the direction of the fast radio burst -- vanished almost four years ago. In a few months, we might get another chance to find out if we are correct. [...]

The Laser Interferometer Gravitational-Wave Observatory (LIGO) has found two binary neutron star mergers. Crucially, the second, known as GW190425, occurred when a new FRB-hunting telescope called CHIME was also operational. However, being new, it took CHIME two years to release its first batch of data. When it did so, [Alexandra Moroianu, a masters student at the University of Western Australia and lead author of the study] quickly identified a fast radio burst called FRB 20190425A which occurred only two and a half hours after GW190425. Exciting as this was, there was a problem -- only one of LIGO's two detectors was working at the time, making it very uncertain where exactly GW190425 had come from. In fact, there was a 5% chance this could just be a coincidence. Worse, the Fermi satellite, which could have detected gamma rays from the merger -- the "smoking gun" confirming the origin of GW190425 -- was blocked by Earth at the time. [...]

LIGO and two other gravitational wave detectors, Virgo and KAGRA, will turn back on in May this year, and be more sensitive than ever, while CHIME and other radio telescopes are ready to immediately detect any FRBs from neutron star mergers. In a few months, we may find out if we've made a key breakthrough -- or if it was just a flash in the pan.

"The World Health Organization on Friday called on China to release new data linking the Covid pandemic's origins to animal samples at Wuhan Market after the country recently took down the research," reports CNBC.

The existence of the new data was revealed by the Atlantic earlier this week, in an article reporting that the newly-discovered samples showed the virus was present in creatures for sale there near the very beginning of the pandemic: A new analysis of genetic sequences collected from the market shows that raccoon dogs being illegally sold at the venue could have been carrying and possibly shedding the virus at the end of 2019. It's some of the strongest support yet, experts told me, that the pandemic began when SARS-CoV-2 hopped from animals into humans, rather than in an accident among scientists experimenting with viruses....

The genetic sequences were pulled out of swabs taken in and near market stalls around the pandemic's start. They represent the first bits of raw data that researchers outside of China's academic institutions and their direct collaborators have had access to. A few weeks ago, the data appeared on an open-access genomic database called GISAID, after being quietly posted by researchers affiliated with the country's Center for Disease Control and Prevention. By almost pure happenstance, scientists in Europe, North America, and Australia spotted the sequences, downloaded them, and began an analysis.

The samples were already known to be positive for the coronavirus, and had been scrutinized before by the same group of Chinese researchers who uploaded the data to GISAID. But that prior analysis, released as a preprint publication in February 2022, asserted that "no animal host of SARS-CoV-2 can be deduced...." The new analysis, led by Kristian Andersen, Edward Holmes, and Michael Worobey — three prominent researchers who have been looking into the virus's roots — shows that that may not be the case. Within about half a day of downloading the data from GISAID, the trio and their collaborators discovered that several market samples that tested positive for SARS-CoV-2 were also coming back chock-full of animal genetic material — much of which was a match for the common raccoon dog. Because of how the samples were gathered, and because viruses can't persist by themselves in the environment, the scientists think that their findings could indicate the presence of a coronavirus-infected raccoon dog in the spots where the swabs were taken....

The new analysis builds on extensive previous research that points to the market as the source of the earliest major outbreak of SARS-CoV-2: Many of the earliest known COVID-19 cases of the pandemic were clustered roughly in the market's vicinity. And the virus's genetic material was found in many samples swabbed from carts and animal-processing equipment at the venue, as well as parts of nearby infrastructure, such as storehouses, sewage wells, and water drains. Raccoon dogs, creatures commonly bred for sale in China, are also already known to be one of many mammal species that can easily catch and spread the coronavirus. All of this left one main hole in the puzzle to fill: clear-cut evidence that raccoon dogs and the virus were in the exact same spot at the market, close enough that the creatures might have been infected and, possibly, infectious.

That's what the new analysis provides. Think of it as finding the DNA of an investigation's main suspect at the scene of the crime.
The article also notes that the genetic sequences "also vanished from the database shortly after the international team of researchers notified the Chinese researchers of their preliminary findings, without explanation." And it adds that all along China has "vehemently" fought the theory that Covid-19 originated from live animals being sold at Wuhan market. Although "in June 2021, a team of researchers published a study documenting tens of thousands of mammals for sale in wet markets in Wuhan between 2017 and late 2019, including at Huanan."

"The animals were kept in largely illegal, cramped, and unhygienic settings — conditions conducive to viral transmission — and among them were more than 1,000 raccoon dogs." And there's even photos of raccoon dogs for sale at the market in December of 2019.


More coverage of the newly-discovered data is now appearing in numerous news outlets, including the New York Times, NBC News, ABC News, the Guardian, PBS, and Science.

A voiceprint program used by millions of Australians to access data held by government agencies can be fooled by an AI-generated voice, reports the Guardian. From the report: Centrelink and the Australian Taxation Office (ATO) both give people the option of using a "voiceprint", along with other information, to verify their identity over the phone, allowing them to then access sensitive information from their accounts. Using just four minutes of audio, a Guardian Australia journalist was able to generate a clone of their own voice and was then able to use this, combined with their customer reference number, to gain access to their own Centrelink self-service account.

Anyone trying to use voiceprint also needs to know the account-holder's customer reference number, which is not normally publicly available, but the number is not treated as securely as a password and is included in correspondence from Centrelink and other service providers, such as childcare centers. The self-service phone system allows people to access sensitive material such as information on their payment of benefits and to request documents to be sent by mail, including replacement concession or healthcare cards. Services Australia declined to say if the voiceprint technology would be changed or removed from Centrelink.

An anonymous reader quotes a report from The Guardian: More than 1,000 scientists and postgraduate students were barred from working in the UK last year on national security grounds, amid a major government crackdown on research collaborations with China. Figures obtained by the Guardian reveal that a record 1,104 scientists and postgraduate students were rejected by Foreign Office vetting in 2022, up from 128 in 2020 and just 13 in 2016.

The sharp increase follows a hardening of the government's stance on scientific ties with China, with warnings from MI5 of a growing espionage threat, major research centers being quietly shut down and accusations by a government minister that China's leading genomics company had regularly sought to hack into the NHS's genetic database. Geopolitical tensions stepped up further this week, as the US, Australia and the UK announced a multi-decade, multibillion-dollar deal aimed at countering China's military expansion in the Indo-Pacific. China said the Aukus plan to build a combined fleet of elite nuclear-powered submarines was "a path of error and danger."

The Foreign Office declined to give a breakdown by nationality, but data supplied by leading universities including Oxford, Cambridge and Imperial College suggests that, at these institutions at least, Chinese academics account for a majority of those denied clearance. Some have welcomed the policy shift, with one security expert saying the number of academics being barred is "commensurate with the threat." But leading scientists say the scheme is leaving universities struggling to recruit the best talent from abroad. "A majority of applicants are thought to be scientists seeking to move to the UK to take up offers of research degrees or fellowships," adds the Guardian. "But the Guardian is also aware of researchers, including five Chinese scientists at Imperial college, who did not pass clearance despite having already held positions at UK universities for several years -- and who may have had to leave the UK as a result."

Facebook-parent Meta Platforms said on Saturday that it would end availability of news content for Canadians on its platforms if the country's Online News Act passes in its current form. From a report: The "Online News Act," or House of Commons bill C-18, introduced in April last year laid out rules to force platforms like Meta and Alphabet's Google to negotiate commercial deals and pay news publishers for their content. "A legislative framework that compels us to pay for links or content that we do not post, and which are not the reason the vast majority of people use our platforms, is neither sustainable nor workable," a Meta spokesperson said as reason to suspend news access in the country. Meta's move comes after Google last month started testing limited news censorship as a potential response to the bill. Canada's news media industry has asked the government for more regulation of tech companies to allow the industry to recoup financial losses it has suffered in the years as tech giants like Google and Meta steadily gain greater market share of advertising. We've watched this movie before.

"Based on initial data review, vehicle is healthy," Relativity Space tweeted today. "More info to follow on cause of aborts today. Thanks for playing."

Remaining back on the launchpad is the largest 3D printed object ever to exist. And they're still hoping to launch it into space.

They'd planned a launch this morning from Cape Canaveral, Florida of a 110-foot rocket (33.5 meters) on a mission they're calling GLHF — "Good Luck, Have Fun".

The rocket's makers — California-based Relativity Space — call it "the world's first 3D printed rocket." A full 85% of the rocket's weight comes from 3D printed parts, explains Wired, and "only the computing system, electronics, and readily available parts like fasteners were not." Named Terran 1, the 7.5-foot-wide rocket (2.2 meters) inaugurates the company's ambitious plans for 3D printing in space: Relativity Space wants to use Terran 1 to (comparatively) cheaply lift satellites for other companies and NASA into Earth orbit. It also plans to construct Terran R, a larger, more powerful, fully reusable rocket that the company hopes will compete with SpaceX's Falcon 9, which has a smaller payload capacity and only reuses the rocket's first stage. In late 2024, Relativity plans to test using Terran R to launch payloads to Mars; another startup, Impulse Space, will provide the lander.
From the company's web site: Like its structure, all Relativity engines are 3D printed and use liquid oxygen and liquid natural gas, which are not only the best for rocket propulsion, but also for reusability, and the easiest to eventually transition to methane on Mars.
The tagline for the company's Twitter feed says they're "Building humanity's multiplanetary future." And excitement is running high, reports Spaceflight Now" "There are a number of firsts here potentially on this rocket," said Josh Brost, vice president of revenue operations at Relativity Space....

"Hard to believe the day is nearly here to launch Terran 1, our first rocket!" Tim Ellis, co-founder and CEO of Relativity Space tweeted Tuesday....

The company now boasts some 1,000 employees, a million-square-foot headquarters and factory in Long Beach, California, and $1.3 billion in venture capital and equity fundraising, including an early $500,000 investment from billionaire Mark Cuban. In 2021, the company reached a valuation of $4.2 billion before launching any rockets....

"No new company has ever had their liquid rocket make it to space on their first attempt," Brost, also a former engineer and manager at SpaceX, told Spaceflight Now in a pre-launch interview. "So if everything goes incredibly well, and we achieve orbit on our first launch ... that would be a remarkable milestone for us, which we would be, of course, over the moon excited about. But that doesn't define success for us."
Wired adds that they're not the only company working on space-related 3D printing: Australia's Fleet Space has already been producing lightweight, 3D-printed radio frequency antennas for satellites. Next year, using printers half the size of a bus, they plan to create a satellite constellation called Alpha that will be entirely 3D-printed.... Flavia Tata Nardini, the company's CEO, believes space-based 3D printing is coming next. "In my ideal future, in 10 to 15 years, I won't have to launch satellites from here; I can build them up there."

An anonymous reader quotes a report from Phys.Org: Australian scientists have discovered an enzyme that converts air into energy. The finding, published in the journal Nature, reveals that this enzyme uses the low amounts of the hydrogen in the atmosphere to create an electrical current. This finding opens the way to create devices that literally make energy from thin air. The research team, led by Dr. Rhys Grinter, Ph.D. student Ashleigh Kropp, and Professor Chris Greening from the Monash University Biomedicine Discovery Institute in Melbourne, Australia, produced and analyzed a hydrogen-consuming enzyme from a common soil bacterium.

In this Nature paper, the researchers extracted the enzyme responsible for using atmospheric hydrogen from a bacterium called Mycobacterium smegmatis. They showed that this enzyme, called Huc, turns hydrogen gas into an electrical current. Dr. Grinter notes, "Huc is extraordinarily efficient. Unlike all other known enzymes and chemical catalysts, it even consumes hydrogen below atmospheric levels -- as little as 0.00005% of the air we breathe." The researchers used several cutting-edge methods to reveal the molecular blueprint of atmospheric hydrogen oxidation. They used advanced microscopy (cryo-EM) to determine its atomic structure and electrical pathways, pushing boundaries to produce the most resolved enzyme structure reported by this method to date. They also used a technique called electrochemistry to demonstrate the purified enzyme creates electricity at minute hydrogen concentrations.

Laboratory work performed by Kropp shows that it is possible to store purified Huc for long periods. "It is astonishingly stable. It is possible to freeze the enzyme or heat it to 80 degrees celsius, and it retains its power to generate energy," Kropp said. "This reflects that this enzyme helps bacteria to survive in the most extreme environments. " Huc is a "natural battery" that produces a sustained electrical current from air or added hydrogen. While this research is at an early stage, the discovery of Huc has considerable potential to develop small air-powered devices, for example as an alternative to solar-powered devices. "Once we produce Huc in sufficient quantities, the sky is quite literally the limit for using it to produce clean energy."

A new disease caused solely by plastics has been discovered in seabirds. The birds identified as having the disease, named plasticosis, have scarred digestive tracts from ingesting waste, scientists at the Natural History Museum in London say. From a report: It is the first recorded instance of specifically plastic-induced fibrosis in wild animals, researchers say. Plastic pollution is becoming so prevalent that the scarring was widespread across different ages of birds, according to the study, published in the Journal of Hazardous Materials. Young birds were found to have the disease, and it is thought chicks were being fed the plastic pollution by parents accidentally bringing it back in food. Scientists, including the Natural History Museum's Dr Alex Bond and Dr Jennifer Lavers, studied flesh-footed shearwaters from Australia's Lord Howe Island to look at the relationship between levels of ingested plastic and the proventriculus organ -- the first part of a bird's stomach. They found that the more plastic a bird had ingested, the more scarring it had. The disease can lead to the gradual breakdown of tubular glands in the proventriculus. Losing these glands can cause the birds to become more vulnerable to infection and parasites and affect their ability to digest food and absorb some vitamins.

MIT Technology Review has revealed two cases in which babies conceived with the three-parent baby technique have shown what scientists call "reversion." "In both cases, the proportion of mitochondrial genes from the child's mother has increased over time, from less than 1% in both embyros to around 50% in one baby and 72% in another," they report. From the report: When the first baby born using a controversial procedure that meant he had three genetic parents was born back in 2016, it made headlines. The baby boy inherited most of his DNA from his mother and father, but he also had a tiny amount from a third person. The idea was to avoid having the baby inherit a fatal illness. His mother carried genes for a disease in her mitochondria. Swapping these with genes from a donor -- a third genetic parent -- could prevent the baby from developing it. The strategy seemed to work. Now clinics in other countries, including the UK, Greece, and Ukraine, are offering the same treatment. It was made legal in Australia last year. But it might not always be successful. [...]

Fortunately, both babies were born to parents without genes for mitochondrial disease; they were using the technique to treat infertility. But the scientists behind the work believe that around one in five babies born using the three-parent technique could eventually inherit high levels of their mothers' mitochondrial genes. For babies born to people with disease-causing mutations, this could spell disaster -- leaving them with devastating and potentially fatal illness. The findings are making some clinics reconsider the use of the technology for mitochondrial diseases, at least until they understand why reversion is happening. "These mitochondrial diseases have devastating consequences," says Bjorn Heindryckx at Ghent University in Belgium, who has been exploring the treatment for years. "We should not continue with this." "It's dangerous to offer this procedure [for mitochondrial diseases]," says Pavlo Mazur, an embryologist based in Kyiv, Ukraine, who has seen one of these cases firsthand.

Australia is preparing for its next step away from fossil fuels by creating a market to replace the spinning coal plant turbines that help stabilize the power grid. From a report: The government's adviser on energy policy, the Australian Energy Market Commission, is consulting on a rule change for a spot market in inertia provision, it said in a statement on Thursday. Australia's world-leading usage of wind, solar and batteries has led to "new and previously unobserved operational conditions," it said.

Conventional power plants use turbines that keep revolving even when the fuel that's forcing them to move stops burning. It's a process known as inertia, which helps network operators maintain stability, smooth over disturbances in the grid and prevent blackouts. However, solar panels and wind turbines generally stop and start almost instantaneously -- hence the AEMC's call for other sources of inertia.

If an artificial intelligence machine can be named as an inventor for a patent, pet cats could be next, lawyers said at the UK's top court arguing only humans can be inventors in law. From a report: The UK's Supreme Court will decide whether an AI machine can be named as an inventor and who may own the patent. Imagination Engines founder, Stephen Thaler, challenged the rejection of his patent applications naming his AI machine as inventor for a beverage container and a flashing light. Allowing an AI machine to be named as the inventor can open doors to "plainly ridiculous assertion," Stuart Baran, a lawyer for the patent office, said in documents prepared for the case. Should the judges rule in favor of Thaler inventors could include "my cat Felix" or "cosmic forces," he said. Thaler tried registering the patent naming his system, DABUS, as inventor in several countries but was successful only in Australia and South Africa, according to the court documents.

Pennsylvania State University has an announcement. "Six massive galaxies discovered in the early universe are upending what scientists previously understood about the origins of galaxies in the universe." "These objects are way more massiveâ than anyone expected," said Joel Leja, assistant professor of astronomy and astrophysics at Penn State, who modeled light from these galaxies. "We expected only to find tiny, young, baby galaxies at this point in time, but we've discovered galaxies as mature as our own in what was previously understood to be the dawn of the universe."

Using the first dataset released from NASA's James Webb Space Telescope, the international team of scientists discovered objects as mature as the Milky Way when the universe was only 3% of its current age, about 500-700 million years after the Big Bang.... In a paper published February 22 in Nature, the researchers show evidence that the six galaxies are far more massive than anyone expected and call into question what scientists previously understood about galaxy formation at the very beginning of the universe. "The revelation that massive galaxy formation began extremely early in the history of the universe upends what many of us had thought was settled science," said Leja. "We've been informally calling these objects 'universe breakers' — and they have been living up to their name so far."

Leja explained that the galaxies the team discovered are so massive that they are in tension with 99% of models for cosmology. Accounting for such a high amount of mass would require either altering the models for cosmology or revising the scientific understanding of galaxy formation in the early universe — that galaxies started as small clouds of stars and dust that gradually grew larger over time. Either scenario requires a fundamental shift in our understanding of how the universe came to be, he added. "We looked into the very early universe for the first time and had no idea what we were going to find," Leja said. "It turns out we found something so unexpected it actually creates problems for science. It calls the whole picture of early galaxy formation into question."
"My first thought was we had made a mistake and we would just find it and move on with our lives," Leja says in the statement. "But we have yet to find that mistake, despite a lot of trying."

"While the data indicates they are likely galaxies, I think there is a real possibility that a few of these objects turn out to be obscured supermassive black holes. Regardless, the amount of mass we discovered means that the known mass in stars at this period of our universe is up to 100 times greater than we had previously thought. Even if we cut the sample in half, this is still an astounding change."

Phys.org got a more detailed explantion from one of the paper's co-authors: It took our home galaxy the entire life of the universe for all its stars to assemble. For this young galaxy to achieve the same growth in just 700 million years, it would have had to grow around 20 times faster than the Milky Way, said Labbe, a researcher at Australia's Swinburne University of Technology. For there to be such massive galaxies so soon after the Big Bang goes against the current cosmological model which represents science's best understanding of how the universe works. According to theory, galaxies grow slowly from very small beginnings at early times," Labbe said, adding that such galaxies were expected to be between 10 to 100 times smaller. But the size of these galaxies "really go off a cliff," he said....

The newly discovered galaxies could indicate that things sped up far faster in the early universe than previously thought, allowing stars to form "much more efficiently," said David Elbaz, an astrophysicist at the French Atomic Energy Commission not involved in the research. is could be linked to recent signs that the universe itself is expanding faster than we once believed, he added.

This subject sparks fierce debate among cosmologists, making this latest discovery "all the more exciting, because it is one more indication that the model is cracking," Elbaz said.

Unlocking exclusive access has been a long-held promise of a lot of NFT-based communities. And now, Spotify is helping some of them realize that claim with token-gated playlists. TechCrunch reports: According to a series of tweets by Kingship, a metaverse band signed to Universal Music Group (UMG), the streaming company is piloting playlists that could be unlocked through NFTs in certain geographies. Under the pilot, Kingship has released a special playlist that could be accessed only by Kingship key card NFT holders. The group posted a series of steps that involves linking a crypto wallet like Metamask, Trust Wallet, Rainbow, Ledger Live, or Zerion to authenticate the NFT that unlocks the playlist. Kingship said that currently, this experience is only available to Android users in the U.S., the U.K., Germany, Australia and New Zealand. "At Spotify, we routinely conduct a number of tests in an effort to improve our user experience. Some of those end up paving the path for our broader user experience and others serve only as important learnings. We have no further news to share on future plans at this time," a Spotify spokesperson said.

An anonymous reader quotes a report from CBC: Google is blocking some Canadian users from viewing news content in what the company says is a test run of a potential response to the Liberal government's online news bill. Also known as Bill C-18, the Online News Act would require digital giants such as Google and Meta, which owns Facebook, to negotiate deals that would compensate Canadian media companies for republishing their content on their platforms. The company said Wednesday that it is temporarily limiting access to news content for under four per cent of its Canadian users as it assesses possible responses to the bill. The change applies to its ubiquitous search engine as well as the Discover feature on Android devices, which carries news and sports stories. All types of news content are being affected by the test, which will run for about five weeks, the company said. That includes content created by Canadian broadcasters and newspapers.

In a news release, the Canadian Association of Broadcasters (CAB) said Google's tactics just reinforce why Bill C-18 is so "vital," adding that Google and other global digital giants are showing they do not intend to play fair. "These are bully tactics, and Google is trying to push the Senate to back down on Bill C-18. We hope senators will see these actions for what they are," said CAB president Kevin Desjardins. "Bill C-18 was introduced to set up fair negotiations between news organizations and these global digital giants on the value of their news content. Google has shown they're willing to block Canadians' vital access to legitimate news content to maintain their dominance in the advertising field." Meta threatened to stop the sharing of news links in Canada last year if C-18 passed as currently written.

The social media company temporarily shut down news feeds in Australia after a similar law was introduced. It took effect in March 2021 and has largely worked, according to a government report.

CBC notes: "More than 450 news outlets in Canada have closed since 2008, including 64 in the last two years."

Long-time Slashdot reader destinyland writes: Meta announced a new $11.99-a-month subscription service on Sunday (or $14.99-a-month for Android and iOS). For your money you mainly get the privilege of authenticating your own account with a government ID, so that it can then display the official "verified" badge. (Accounts must have a prior posting history, with account holders verified to be at least 18 years old.)

Meta promises they won't change already-verified Facebook and Instagram accounts — at least, not "as we test and learn." But they immediately follow that sentence by warning that in the longer-term they're "evolving the meaning" of verification, aiming to making everyone want to subscribe. Meta calls this "expanding access."

Paying subscribers will also get:

— Protection from account impersonation (at a higher level that's apparently not made available to non-paying members), including "proactive account monitoring".

— "Help when you need it with access to a real person for common account issues."

— Exclusive "stickers" for Facebook and Instagram Stories and Facebook Reels, plus 100 free Facebook "stars" each month "so you can show your support for other creators."


But most importantly, Meta is also promising to grant "increased visibility and reach" to paying members, promising "prominence" in parts of the service (including search, recommendations, and in comments). Although a footnote warns this may vary — depending on what you're trying to post about — and all content "will be treated according to our existing guidelines for recommendations on Instagram or Facebook and our Content Guidelines."

George Takei once calculated roughly 80% of your friends never see the things you post on Facebook. But now Facebook is deliberately evolving into a two-tiered system where some will always be relegated to less-likely-to-be-seen status, always outshined by wealthier friends with $144 a year to spend on upgrading their Facebook accounts.

The internet already has a two-tiered system for news, where the best news articles are only available to those with the funds to climb over multiple paywalls. But now even the lower tier of discourse — all that non-journalistic content floating around Facebook — will transform from a pool of burbling anger and misinformation into something worse. It's like Facebook's algorithm went from promoting just the most divisive content to promoting content from whoever most desires to foist their ideas onto other people. This may not end well.

Is it just me, or does this seem like a desperate grab for money?

— They're monetizing Meta's inability to stop account impersonators.

— Their announcement admits that "access to account support" remains a top request of their creators. Yet paying members are apparently more likely to get it than non-paying members. Maybe that can be their new marketing slogan. "Help when you need it — sold separately."

— This is happening. It becomes available for purchase this week on Instagram or Facebook in Australia and New Zealand.

"Astronomers spotted an unexpected trail in the gas surrounding a dwarf galaxy while using the Hubble Space Telescope...." writes Hot Hardware. "The light emitting from the trail traveled more than 7.5 billion years to reach Earth and is thought to be traveling at a breakneck speed of 1,600km/s (3.5 million mph).

Science Alert says it could be "the smoking gun pointing to a runaway supermassive black hole."

More from Universe Today: Supermassive black holes (SMBHs) lurk in the center of large galaxies like ours. From their commanding position in the galaxy's heart, they feed on gas, dust, stars, and anything else that strays too close, growing more massive as time passes. But in rare circumstances, an SMBH can be forced out of its position and hurtle through space as a rogue SMBH.

In a new paper, researchers from Canada, Australia, and the USA present evidence of a rogue SMBH that's tearing through space and interacting with the circumgalactic medium (CGM.) Along the way, the giant is creating shock waves and triggering star formation.... The paper hasn't been peer-reviewed yet....

In their paper, the authors explain how an SMBH can be cast out of its host galaxy. It always starts when galaxies merge. That leads to the formation of a binary SMBH at the center of the merger remnant. The binary SMBH can be very long-lived, surviving for as long as one billion years before merging. If during that time, a third SMBH reaches the galactic center, then a three-body interaction can give one of the SMBHs a velocity boost, and it can be driven from the galaxy.
Hot Hardware adds that "This is not the first time a supermassive black hole has been found ejected from the center of its host galaxy. However, this is the first time one has been detected speeding across intergalactic space and believed to be inactive."

And RockDoctor (Slashdot reader #15,477) explains that "After the collision and ejection from the galaxy core, the passage of the black hole through the galaxy and it's surrounding material produced a burst of star formation along that line, which we now see as a faint linear streak of light....

"Those who like doom-laden prophecies will be upset to hear that, because we can see this moving across the plane of the sky, it is never going to come any where near us."

An anonymous reader quotes a report from TechCrunch: Australian software giant Atlassian and Envoy, a startup that provides workplace management services, were at loggerheads on Thursday over a data breach that exposed the data of thousands of Atlassian employees. As first reported by Cyberscoop, a hacking group known as SiegedSec leaked data on Telegram this week that it claimed to have stolen from Atlassian. This data includes the names, email addresses, work departments and phone numbers of approximately 13,200 Atlassian employees, along with floor plans of Atlassian offices located in San Francisco and Sydney, Australia.

Atlassian was quick to point the finger of blame for the breach at Envoy, which the Sydney-headquartered company uses to organize its office spaces. "On February 15, 2023, we learned that data from Envoy, a third-party app that Atlassian uses to coordinate in-office resources, was compromised and published," Atlassian spokesperson Megan Sutton said in a statement shared with TechCrunch. "Atlassian product and customer data is not accessible via the Envoy app and therefore not at risk." Envoy, however, was just as quick to rebuff Atlassian's claims. Envoy spokesperson April Marks told TechCrunch that the startup is "not aware of any compromise to our systems," adding that initial research had shown that "a hacker gained access to an Atlassian employee's valid credentials to pivot and access the Atlassian employee directory and office floor plans held within Envoy's app."

Soon after the startup's denial, Atlassian changed its stance to align more closely with Envoy. Atlassian's Sutton told TechCrunch that the company's internal investigation since revealed that attackers had actually compromised Atlassian data from the Envoy app "using an Atlassian employee's credentials that had been mistakenly posted in a public repository by the employee." "As such, the hacking group had access to data visible via the employee account which included the published office floor plans and public Envoy profiles of other Atlassian employees and contractors," Sutton added. "The compromised employee's account was promptly disabled eliminating any further threat to Atlassian's Envoy data. Atlassian product and customer data is not accessible via the Envoy app and therefore not at risk." In a statement to TechCrunch, Envoy's Marks ruled out a breach on its end: "We found evidence in the logs of requests that confirms the hackers obtained valid user credentials from an Atlassian employee account and used that access to download the affected data from Envoy's app."

An anonymous reader quotes a report from The Guardian: Australians would gain greater control of their personal information, including the ability to opt out of targeted ads, erase their data and sue for serious breaches of privacy, under a proposal to the Albanese government. On Thursday the attorney general, Mark Dreyfus, will release a review conducted by his department into modernization of the Privacy Act which calls to expand its remit to small businesses and add new safeguards for use of data by political parties. Although the document is not government policy, in January Dreyfus told Guardian Australia the right to sue for privacy breaches and European-style reforms such as the right to be forgotten would be considered for the next tranche of legislation.

In 2022 the Albanese government passed a bill increasing penalties for companies that fail to protect customer data in the wake of major data breaches at telco Optus and health insurer Medibank. A summary section of the review, seen in advance by Guardian Australia, called for the exemption from the Privacy Act for small businesses to be abolished, citing community expectations that if small businesses are provided personal information "they will keep it safe." But first the government should conduct an "impact analysis" and give support to ensure small businesses can comply with their obligations, it said. Despite calls to abolish the privacy exemptions for political parties, the review proposed only increased safeguards, such as for parties to publish a privacy policy and not target voters "based on sensitive information or traits" except for political opinions, membership of a political association, or a trade union. "There was very strong support for increasing the protections for personal information under the Act," the review said.

The review called for new limits on targeted advertising, including to prohibit targeting to a child except where it is in their "best interests," and to provide others with an "an unqualified right to opt-out" of targeted ads and their information being disclosed for direct marketing purposes. The Privacy Act should include a new overarching requirement that "the collection, use and disclosure of personal information must be fair and reasonable in the circumstances," it said. The review also proposes individual rights modeled on the European Union's general data protection regulation including to: object to the collection, use or disclosure of personal information; request erasure of personal information; and to de-index online search results containing sensitive information, excessive detail or "inaccurate, out-of-date, incomplete, irrelevant, or misleading" information. The review suggested that consent should be required for collection and use of precise geolocation tracking data. The government should "consult on introducing a criminal offense for malicious re-identification of de-identified information where there is an intention to harm another or obtain an illegitimate benefit," it said. The report said that individuals wanted "more agency to seek redress for interferences with their privacy," proposing the creation of a right to sue for "serious invasions of privacy," which was also a recommendation of the Australian Law Reform Commission in 2014.

An anonymous reader quotes a report from Reuters: The Australian government will examine surveillance technology used in offices of the defense department, Defense Minister Richard Marles said on Thursday, amid reports that Chinese-made cameras installed there posed a security risk. "This is an issue and ... we're doing an assessment of all the technology for surveillance within the defense (department) and where those particular cameras are found, they are going to be removed," Marles told ABC Radio in an interview. Opposition lawmaker James Paterson said his own audit had revealed almost 1,000 units of equipment by Hangzhou Hikvision Digital Technology and Dahua Technology Co -- two partly state-owned Chinese firms -- were installed across more than 250 Australian government offices.

Paterson, the shadow minister for cyber security and countering foreign interference, urged the government to urgently come up with a plan to remove all such cameras. Marles said the issue was significant though adding: "I don't think we should overstate it." Hikvision said it was "categorically false" to represent the company as a threat to Australia's national security as it could not access the video data of end users, manage end-user databases or sell cloud storage in Australia. "Our cameras are compliant with all applicable Australian laws and regulations and are subject to strict security requirements," a spokesperson said in an emailed response.

Polluting single-use plastic production rose globally by 6 million tons per year from 2019 to 2021 despite tougher worldwide regulations, with producers making "little progress" to tackle the problem and boost recycling, new research showed on Monday. Reuters reports: Single-use plastics have emerged as one of the world's most pressing environmental threats, with vast amounts of waste buried in landfills or dumped untreated in rivers and oceans. The manufacturing process is also a major source of climate-warming greenhouse gas. But while growth has slowed recently, the production of single-use plastic from "virgin" fossil fuel sources is still nowhere near its peak, and the use of recycled feedstocks remains "at best a marginal activity," Australia's Minderoo Foundation said in its Plastic Waste Makers Index. "Make no mistake, the plastic waste crisis is going to get significantly worse before we see an absolute year-on-year decline in virgin single-use plastic consumption," it said.

Exxon Mobil was at the top of the list of global petrochemical companies producing virgin polymers used in single-use plastics, followed by China's Sinopec. Sinopec also leads the way when it comes to building new production facilities over the 2019-2027 period, the report said, with more than 5 million tons of annual capacity planned. Exxon Mobil was second with around 4 million tons. [...] Around 137 million tons of single-use plastics were produced from fossil fuels in 2021, and it is expected to rise by another 17 million tons by 2027, the researchers said.
