An anonymous reader quotes a report from The Register: Not long after Windows PCs and servers at the Australian limb of audit and tax advisory Grant Thornton started BSODing last Friday, senior systems engineer Rob Woltz remembered a small but important fact: When PCs boot, they consider barcode scanners no differently to keyboards. That knowledge nugget became important as the firm tried to figure out how to respond to the mess CrowdStrike created, which at Grant Thornton Australia threw hundreds of PCs and no fewer than 100 servers into the doomloop that CrowdStrike's shoddy testing software made possible. [...] The firm had the BitLocker keys for all its PCs, so Woltz and colleagues wrote a script that turned them into barcodes that were displayed on a locked-down management server's desktop. The script would be given a hostname and generate the necessary barcode and LAPS password to restore the machine.

Woltz went to an office supplies store and acquired an off-the-shelf barcode scanner for AU$55 ($36). At the point when rebooting PCs asked for a BitLocker key, pointing the scanner at the barcode on the server's screen made the machines treat the input exactly as if the key was being typed. That's a lot easier than typing it out every time, and the server's desktop could be accessed via a laptop for convenience. Woltz, Watson, and the team scaled the solution -- which meant buying more scanners at more office supplies stores around Australia. On Monday, remote staff were told to come to the office with their PCs and visit IT to connect to a barcode scanner. All PCs in the firm's Australian fleet were fixed by lunchtime -- taking only three to five minutes for each machine. Watson told us manually fixing servers needed about 20 minutes per machine.

An anonymous reader quotes a report from The Guardian: A team of Australian scientists is genetically engineering a common fly species so that it can eat more of humanity's organic waste while producing ingredients for making everything from lubricants and biofuels to high-grade animal feeds. Black soldier flies are already being used commercially to consume organic waste, including food waste, but tweaking their genetics could widen the range of waste their larvae consume while, in the process, producing fatty compounds and enzymes. In a scientific paper, the team based at Sydney's Macquarie University outlined their hopes for the flies and how they could also cut the amount of planet-warming methane produced when organic waste breaks down.

"We are heading towards a climate disaster, and landfill waste releases methane. We need to get that to zero," Dr Kate Tepper, a lead author of the paper, said. Dr Maciej Maselko runs an animal synthetic biology lab at Macquarie University where Tepper has already started engineering the flies. Maselko said insects would be the "next frontier" in dealing with the planet's waste management problem, which weighs in at about 1 billion tons a year in food waste alone. Black soldier flies are found in all continents except Antarctica. "If you've got a compost bin, then you've probably got some," Maselko said. The fly larvae can eat double their body weight a day and, like other insects, their larvae are used for animal feed. Maselko said the flies could already do the job of consuming waste faster than microbes. The university team has created a spin-off company, EntoZyme, to commercialize their work and hopes to have the first genetically engineered flies for use in waste facilities by the end of the year. [...]

Creating a suite of genetically engineered flies would see them also produce enzymes used in animal feeds, textiles and pharmaceuticals, and fatty compounds that can be used to make biofuels and lubricants. Another proposed use is for some flies to be able to consume contaminated waste, which would then leave behind their poo that could be used as fertilizer. Tepper said flies can be engineered to deal with pollutants in several ways, including by breaking pollutants down into less toxic or inorganic compounds, evaporating them into the air or accumulating some pollutants into their bodies that can then be separated, leaving clean organic waste behind. The research has been published in the journal Communications Biology.

The pace of China's clean energy transition "is roughly the equivalent of installing five large-scale nuclear power plants worth of renewables every week," according to a report from Australia's national public broadcaster ABC (shared by long-time Slashdot reader AmiMoJo): A report by Sydney-based think tank Climate Energy Finance (CEF) said China was installing renewables so rapidly it would meet its end-of-2030 target by the end of this month — or 6.5 years early.

It's installing at least 10 gigawatts of wind and solar generation capacity every fortnight...

China accounts for about a third of the world's greenhouse gas emissions. A recent drop in emissions (the first since relaxing COVID-19 restrictions), combined with the decarbonisation of the power grid, may mean the country's emissions have peaked. "With the power sector going green, emissions are set to plateau and then progressively fall towards 2030 and beyond," CEF China energy policy analyst Xuyang Dong said... [In China] the world's largest solar and wind farms are being built on the western edge of the country and connected to the east via the world's longest high-voltage transmission lines...

Somewhat counterintuitively, China has built dozens of coal-fired power stations alongside its renewable energy zones, to maintain the pace of its clean energy transition. China was responsible for 95 per cent of the world's new coal power construction activity last year. The new plants are partly needed to meet demand for electricity, which has gone up as more energy-hungry sectors of the economy, like transport, are electrified. The coal-fired plants are also being used, like the batteries and pumped hydro, to provide a stable supply of power down the transmission lines from renewable energy zones, balancing out the intermittent solar and wind.

Despite these new coal plants, coal's share of total electricity generation in the country is falling. The China Energy Council estimated renewables generation would overtake coal by the end of this year.
CEF director Tim Buckley tells the site that China installed just 1GW of nuclear power last year — compared to 300GW of solar and wind. "They had grand plans for nuclear to be massive but they're behind on nuclear by a decade and five years ahead of schedule on solar and wind." Last year China accounted for 16% of the world's nuclear-generated power — but also more than half the world's coal-fired power generation, according to this year's analysis from the long-running International Energy Agency. The IEA estimated that in 2023, China's electricity demand rose by 6.4%, and they're predicting that by 2026 the country will see an increase "more than half of the EU's current annual electricity consumption."

And yet in China "the rapid expansion of renewable energy sources is expected to meet all additional electricity demand..." according to the IEA analysis. "Coal-fired generation in China is currently on course to experience a slow structural decline, driven by the strong expansion of renewables and growing nuclear generation, as well as moderating economic growth."

There's also some interesting stats on the "CO2 intensity" of power generation around the world. "The EU is expected to record the highest rate of progress in reducing emissions intensity, averaging an improvement of 13% per year. This is followed by China, with annual improvements forecast at 6%, and the United States at 5%."

Robin McKie writes via The Guardian: Scientists with Breakthrough Listen, the world's largest scientific research program dedicated to finding alien civilizations, say a host of technological developments are about to transform the search for intelligent life in the cosmos. These innovations will be outlined at the group's annual conference, which is to be held in the UK for the first time, in Oxford, this week. Several hundred scientists, from astronomers to zoologists, are expected to attend. "There are amazing technologies that are under development, such as the construction of huge new telescopes in Chile, Africa and Australia, as well as developments in AI," said astronomer Steve Croft, a project scientist with Breakthrough Listen. "They are going to transform how we look for alien civilizations."

Among these new instruments are the Square Kilometer Array, made up of hundreds of radio telescopes now being built in South Africa and Australia, and the Vera Rubin Observatory that is being constructed in Chile. The former will become the world's most powerful radio astronomy facility while the latter, the world's largest camera, will be able to image the entire visible sky every three or four nights, and is expected to help discover millions of new galaxies and stars. Both facilities are set to start observations in the next few years and both will provide data for Breakthrough Listen. Using AI to analyze these vast streams of information for subtle patterns that would reveal evidence of intelligent life will give added power to the search for alien civilizations, added Croft.

"Until now, we have been restricted to looking for signals deliberately sent out by aliens to advertise their existence. The new techniques are going to be so sensitive that, for the first time, we will be able to detect unintentional transmissions as opposed to deliberate ones and will be able to spot alien airport radar, or powerful TV transmitters -- things like that." [...] Croft remains optimistic that we will soon succeed in making contact. "We know that the conditions for life are everywhere, we know that the ingredients for life are everywhere. I think it would be deeply weird if it turned out we were the only inhabited planet in the galaxy or in the universe. But you know, it's possible."

Australia's government cybersecurity agency on Tuesday accused a China-backed hacker group of stealing passwords and usernames from two unnamed Australian networks in 2022, adding that the group remained a threat. From a report: A joint report led by the Australian Cyber Security Centre said the hackers, named APT40, had conducted malicious cyber operations for China's Ministry of State Security, the main agency overlooking foreign intelligence. "The activity and techniques overlap with the groups tracked as Advanced Persistent Threat (APT) 40," said the report, which included inputs from lead cyber security agencies for the United States, Britain, Canada, New Zealand, Japan, South Korea and Germany. U.S. and British officials in March had accused Beijing of a sweeping cyberespionage campaign that allegedly hit millions of people including lawmakers, academics and journalists, and companies including defense contractors. They said China-backed "APT31" was responsible for the network intrusion.

An anonymous reader quotes a report from The Guardian: Air pollution exposure can significantly decrease the chance of a live birth after IVF treatment, according to research that deepens concern about the health impacts of toxic air on fertility. Pollutant exposure has previously been linked to increased miscarriage rates and preterm births, and microscopic soot particles have been shown to travel through the bloodstream into the ovaries and the placenta. The latest work suggests that the impact of pollution begins before conception by disrupting the development of eggs. "We observed that the odds of having a baby after a frozen embryo transfer were more than a third lower for women who were exposed to the highest levels of particulate matter air pollution prior to egg collection, compared with those exposed to the lowest levels," said Dr Sebastian Leathersich, a fertility specialist and gynaecologist from Perth who is due to present the findings on Monday at the European Society of Human Reproduction and Embryology annual meeting in Amsterdam. [...]

The study analyzed fertility treatments in Perth over an eight-year period, including 3,659 frozen embryo transfers from 1,836 patients, and tracked whether outcomes were linked to the levels of fine particulate matter, known as PM10. The overall live birthrate was about 28% per transfer. However, the success rates varied in line with exposure to pollutants in the two weeks leading up to egg collection. The odds of a live birth decreased by 38% when comparing the highest quartile of exposure to the lowest quartile. "These findings suggest that pollution negatively affects the quality of the eggs, not just the early stages of pregnancy, which is a distinction that has not been previously reported," Leathersich said. The team now plan to study cells directly to understand why pollutants have a negative effect. Previous work has shown that the microscopic particles can damage DNA and cause inflammation in tissues. The report notes that the link between air pollution and live birth "was apparent despite excellent overall air quality during the study period, with PM10 and PM2.5 levels exceeding WHO guidelines on just 0.4% and 4.5% of the study days."

It adds: "Australia is one of just seven countries that met the WHO's guidelines in 2023, and this study is the latest to show evidence of harm even at relatively low levels of pollution."

The study has been published in the journal Human Reproduction.

An anonymous reader quotes a report from CNN: Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued researchers since its discovery by Danish seismologist Inge Lehmann in 1936, and how it moves -- its rotation speed and direction -- has been at the center of a decades-long debate. A growing body of evidence suggests the core's spin has changed dramatically in recent years, but scientists have remained divided over what exactly is happening -- and what it means. Part of the trouble is that Earth's deep interior is impossible to observe or sample directly. Seismologists have gleaned information about the inner core's motion by examining how waves from large earthquakes that ping this area behave. Variations between waves of similar strengths that passed through the core at different times enabled scientists to measure changes in the inner core's position and calculate its spin.

"Differential rotation of the inner core was proposed as a phenomenon in the 1970s and '80s, but it wasn't until the '90s that seismological evidence was published," said Dr. Lauren Waszek, a senior lecturer of physical sciences at James Cook University in Australia. But researchers argued over how to interpret these findings, "primarily due to the challenge of making detailed observations of the inner core, due to its remoteness and limited available data," Waszek said. As a result, "studies which followed over the next years and decades disagree on the rate of rotation, and also its direction with respect to the mantle," she added. Some analyses even proposed that the core didn't rotate at all.

One promising model proposed in 2023 described an inner core that in the past had spun faster than Earth itself, but was now spinning slower. For a while, the scientists reported, the core's rotation matched Earth's spin. Then it slowed even more, until the core was moving backward relative to the fluid layers around it. At the time, some experts cautioned that more data was needed to bolster this conclusion, and now another team of scientists has delivered compelling new evidence for this hypothesis about the inner core's rotation rate. Research published June 12 in the journal Nature not only confirms the core slowdown, it supports the 2023 proposal that this core deceleration is part of a decades-long pattern of slowing down and speeding up. The new findings also confirm that the changes in rotational speed follow a 70-year cycle, said study coauthor Dr. John Vidale, Dean's Professor of Earth Sciences at the University of Southern California's Dornsife College of Letters, Arts and Sciences.

An anonymous reader quotes a report from Ars Technica: Human Rights Watch (HRW) continues to reveal how photos of real children casually posted online years ago are being used to train AI models powering image generators -- even when platforms prohibit scraping and families use strict privacy settings. Last month, HRW researcher Hye Jung Han found 170 photos of Brazilian kids that were linked in LAION-5B, a popular AI dataset built from Common Crawl snapshots of the public web. Now, she has released a second report, flagging 190 photos of children from all of Australia's states and territories, including indigenous children who may be particularly vulnerable to harms. These photos are linked in the dataset "without the knowledge or consent of the children or their families." They span the entirety of childhood, making it possible for AI image generators to generate realistic deepfakes of real Australian children, Han's report said. Perhaps even more concerning, the URLs in the dataset sometimes reveal identifying information about children, including their names and locations where photos were shot, making it easy to track down children whose images might not otherwise be discoverable online. That puts children in danger of privacy and safety risks, Han said, and some parents thinking they've protected their kids' privacy online may not realize that these risks exist.

From a single link to one photo that showed "two boys, ages 3 and 4, grinning from ear to ear as they hold paintbrushes in front of a colorful mural," Han could trace "both children's full names and ages, and the name of the preschool they attend in Perth, in Western Australia." And perhaps most disturbingly, "information about these children does not appear to exist anywhere else on the Internet" -- suggesting that families were particularly cautious in shielding these boys' identities online. Stricter privacy settings were used in another image that Han found linked in the dataset. The photo showed "a close-up of two boys making funny faces, captured from a video posted on YouTube of teenagers celebrating" during the week after their final exams, Han reported. Whoever posted that YouTube video adjusted privacy settings so that it would be "unlisted" and would not appear in searches. Only someone with a link to the video was supposed to have access, but that didn't stop Common Crawl from archiving the image, nor did YouTube policies prohibiting AI scraping or harvesting of identifying information.

Reached for comment, YouTube's spokesperson, Jack Malon, told Ars that YouTube has "been clear that the unauthorized scraping of YouTube content is a violation of our Terms of Service, and we continue to take action against this type of abuse." But Han worries that even if YouTube did join efforts to remove images of children from the dataset, the damage has been done, since AI tools have already trained on them. That's why -- even more than parents need tech companies to up their game blocking AI training -- kids need regulators to intervene and stop training before it happens, Han's report said. Han's report comes a month before Australia is expected to release a reformed draft of the country's Privacy Act. Those reforms include a draft of Australia's first child data protection law, known as the Children's Online Privacy Code, but Han told Ars that even people involved in long-running discussions about reforms aren't "actually sure how much the government is going to announce in August." "Children in Australia are waiting with bated breath to see if the government will adopt protections for them," Han said, emphasizing in her report that "children should not have to live in fear that their photos might be stolen and weaponized against them."

What if across the bottom of the Atlantic Ocean, six high-voltage power cables stretched — each over 2,000 miles long.

CNN reports that a group of entrepreneurs "wants to build what would be the world's largest subsea energy interconnector between continents, linking Europe and North America...to connect places like the United Kingdom's west with eastern Canada, and potentially New York with western France...

"The Europe-US cables could send 6 gigawatts of energy in both directions at the speed of light, said Laurent Segalen, founder of the London-based Megawatt-X renewable energy firm, who is also part of the trio proposing the transatlantic interconnector. That's equivalent to what six large-scale nuclear power plants can generate, transmitted in near-real time." The interconnector would send renewable energy both east and west, taking advantage of the sun's diurnal journey across the sky. "When the sun is at its zenith, we probably have more power in Europe than we can really use," said Simon Ludlam, founder and CEO of Etchea Energy, and one of the trio of Europeans leading the project. "We've got wind and we've also got too much solar. That's a good time to send it to a demand center, like the East Coast of the United States. Five, six hours later, it's the zenith in the East Coast, and obviously, we in Europe have come back for dinner, and we get the reverse flow," he added.

The transatlantic interconnector is still a proposal, but networks of green energy cables are starting to sprawl across the world's sea beds. They are fast becoming part of a global climate solution, transmitting large amounts of renewable energy to countries struggling to make the green transition alone. But they are also forging new relations that are reshaping the geopolitical map and shifting some of the world's energy wars down to the depths of the ocean...

Already, energy cables run between several countries in Europe, most of them allied neighbors. Not all of them carry renewable power exclusively — that's sometimes determined by what makes up each country's energy grid — âbut new ones are typically being built for a green energy future. The UK, where land space for power plants is limited, is already connected with Belgium, Norway, the Netherlands and Denmark under the sea. It has signed up to a solar and wind link with Morocco to take advantage of the North African country's many hours of sunlight and strong trade winds that run across the equator. Similar proposals are popping up around the globe. A project called Sun Cable seeks to send solar power from sunny Australia, where land is abundant, to the Southeast Asian nation of Singapore, which also has plenty of sun but very little room for solar farms. India and Saudi Arabia plan to link their respective power grids via the Arabian Sea, part of a broader economic corridor plan to connect Asia, the Middle East and Europe.

Lego teamed up with the European Space Agency to make Lego pieces from actual meteorite dust, writes Engadget.

"It's a proof of concept to show how astronauts could use moondust to build lunar structures." Consider the sheer amount of energy and money required to haul up building materials from Earth to the Moon. It would be a game changer to, instead, build everything from pre-existing lunar materials. There's a layer of rock and mineral deposits at the surface of the Moon, which is called lunar regolith...

However, there isn't too much lunar regolith here on Earth for folks to experiment with. ESA scientists made their own regolith by grinding up a really old meteorite. [4.5 billion years, according to Lego's site, discovered in Africa in 2000.] The dust from this meteorite was turned into a mixture that was used to 3D print the Lego pieces. Voila. Moon bricks. They click together just like regular Lego bricks, though they only come in one color (space gray obviously.)
"The result is amazing," says ESA Science Officer Aidan Cowley on the Lego site (though "the bricks may look a little rougher than usual. Importantly the clutch power still works, enabling us to play and test our designs.")

"Nobody has built a structure on the Moon," Cowley said in an ESA statement. "So it was great to have the flexibility to try out all kinds of designs and building techniques with our space bricks." And the bricks will also be "helping to inspire the next generation of space engineers," according to the ESA's announcement — since they'll be on display in select Lego stores in the U.S., Canada, the U.K., Spain, France, Germany, the Netherlands, and Australia through September 20th.

After launching in the United States earlier this year, Apple's Vision Pro is now available to buy in China, Japan, and Singapore. "The Apple Vision Pro will also roll out to Germany, France, Australia, the UK, and Canada on July 12th, with preorders for those regions available starting today at 5AM PT," notes The Verge. Apple is documenting the international launch via a recent blog post.

According to CNBC, the device starts at $4,128 (29,999 yuan) in China, compared to $3,500 in the U.S. Meanwhile, Apple is already hard at work on a more budget-friendly model. In Bloomberg's "Power On" newsletter, Apple news-breaker Mark Gurman reports today that the tech giant is "working on a cheaper headset, a second Vision Pro model and augmented-reality glasses to better compete with Meta."

According to Interpol, nearly 4,000 people around the world have been arrested for a variety of online crimes, with $257 million in assets seized. The Record reports: The operation, dubbed First Light, was conducted by police officers from 61 countries and targeted phishing, investment fraud, fake online shopping sites, romance scams, and impersonation scams, according to a statement by Interpol. In addition to arresting thousands of potential cybercriminals, the police also identified over 14,600 other possible suspects across all continents.

During the searches, law enforcement seized suspects' real estate, high-end vehicles, expensive jewelry, and many other high-value items and collections. They also froze 6,745 bank accounts used for transferring money obtained through illegal operations. In one case, the police intercepted $331,000 gleaned from a business email compromise fraud involving a Spanish victim who unknowingly transferred money to someone in Hong Kong. In another case, authorities in Australia successfully recovered $3.7 million on behalf of an impersonation scam victim after the funds were fraudulently transferred to bank accounts in Malaysia and Hong Kong.

The criminal networks identified during the operation were spread around the globe. In Namibia, for example, the police rescued 88 local youths who were forced into conducting scams as part of a sophisticated international crime network, according to Interpol. Law enforcement from Singapore, Hong Kong, and China prevented an attempted tech support scam, saving a 70-year-old victim from losing $281,200 worth of savings.

Earlier this week, WikiLeaks co-founder Julian Assange received a donation of 8.07 bitcoin (worth roughly $500,000) from an anonymous bitcoin whale, "helping to cover the cost of a private jet that flew him out of the U.K. and ultimately to freedom in Australia after he reached a plea deal with the U.S. Department of Justice," reports CoinDesk. From the report: Initially, Assange's wife Stella made an "emergency appeal" to raise 520,000 British pounds to pay for the transport, setting up a crowdfunding page that allowed people to donate in fiat currency via credit cards or bank transfer. With that site notably not allowing crypto for donations, the family quickly moved to set up another page to accept bitcoin.

Up to this point, the bitcoin address has received 34 donations totaling just over $500,000. The overwhelming majority, however, came from just that one 8.07 BTC donation. The original fiat site has also received about $500,000 in donations. "Julian's travel to freedom comes at a massive cost: Julian will owe USD 520,000 which he is obligated to pay back to the Australian government for charter Flight VJ199," Stella Assange wrote on X. "He was not permitted to fly commercial airlines or routes to Saipan and onward to Australia. Any contribution big or small is much appreciated." The jet was organized by the Australian government after Assange reached a historic plea deal on Tuesday, where he pleaded guilty to espionage charges in exchange for his freedom.

National Australia Bank seems to think that monitoring the angle customers hold their phones will offer extra protection against scammers. "Speaking during the Australian Banking Association Conference in Melbourne Wednesday (June 26), CEO Andrew Irvine said the lender introduced more 'friction' to payments processes and new predictive protection tools to spot scammers," reports PYMNTS.com, citing a (paywalled) Bloomberg report. From the report: "We've added tooling that looks at biometrics and the way you actually interact with your devices and how you think about keystrokes," said Irvine, per the report. "If these things are different to how you've used your phone in the past, our intelligence will kick in." Irvine, who called fraudsters the "scourge of our times," also noted that Australia is one of the few countries where bank fraud has declined, the report said.

Still, he said that as scammers have embraced new technology like artificial intelligence, banks have had to shift from making payments fast and simple to adding more steps to protect against fraudulent transactions, per the report. "These threat actors go where the money is," Irvine said, according to the report. "You want to be the best alarm system in the street and right now Australia's leading the way."

WikiLeaks founder Julian Assange has agreed to a plea deal with the U.S. Justice Department over his alleged role in one of the largest U.S. government breaches of classified material. As a result, he will avoid imprisonment in the United States. CNN reports: Under the terms of the new agreement (PDF), Justice Department prosecutors will seek a 62-month sentence -- which is equal to the amount of time Assange has served in a high-security prison in London while he fought extradition to the US. The plea deal would credit that time served, allowing Assange to immediately return to Australia, his native country. The plea deal must still be approved by a federal judge.

Assange had faced 18 counts from a 2019 indictment for his alleged role in the breach that carried a max of up to 175 years in prison, though he was unlikely to be sentenced to that time in full. Assange was being pursued by US authorities for publishing confidential military records supplied by former Army intelligence analyst Chelsea Manning in 2010 and 2011. US officials alleged that Assange goaded Manning into obtaining thousands of pages of unfiltered US diplomatic cables that potentially endangered confidential sources, Iraq war-related significant activity reports and information related to Guantanamo Bay detainees.

Jonathan O'Callaghan reports via Scientific American: Despite more than a century of efforts to show otherwise, it seems Albert Einstein can still do no wrong. Or at least that's the case for his special theory of relativity, which predicts that time ticks slower for objects moving at extremely high speeds. Called time dilation, this effect grows in intensity the closer to the speed of light that something travels, but it is strangely subjective: a passenger on an accelerating starship would experience time passing normally, but external observers would see the starship moving ever slower as its speed approached that of light. As counterintuitive as this effect may be, it has been checked and confirmed in the motions of everything from Earth-orbiting satellites far-distant galaxies. Now a group of scientists have taken such tests one step further by observing more than 1,500 supernovae across the universe to reveal time dilation's effects on a staggering cosmic scale. The researchers' findings, once again, reach an all-too-familiar conclusion. "Einstein is right one more time," says Geraint Lewis of the University of Sydney, a co-author of the study.

In the paper, posted earlier this month on the preprint server arXiv.org, Ryan White of the University of Queensland in Australia and his colleagues used data from the Dark Energy Survey (DES) to investigate time dilation. For the past decade, researchers involved with DES had used the Victor M. Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile to study particular exploding stars called Type 1a supernovae across billions of years of cosmic history. [...] Type 1a supernovae are keystone cosmic explosions caused when a white dwarf -- the slowly cooling corpse of a midsized star -- siphons so much material from a companion that it ignites a thermonuclear reaction and explodes. This explosion occurs once the growing white dwarf reaches about 1.44 times the mass of our sun, a threshold known as the Chandrasekhar limit. This physical baseline imbues all Type 1a supernovae with a fairly consistent brightness, making them useful cosmic beacons for gauging intergalactic distances. "They should all be essentially the same kind of event no matter where you look in the universe," White says. "They all come from exploding white dwarf stars, which happens at almost exactly the same mass no matter where they are."

The steadfastness of these supernovae across the entire observable universe is what makes them potent probes of time dilation -- nothing else, in principle, should so radically and precisely slow their apparent progression in lockstep with ever-greater distances. Using the dataset of 1,504 supernovae from DES, White's paper shows with astonishing accuracy that this correlation holds true out to a redshift of 1.2, a time when the universe was about five billion years old. "This is the most precise measurement" of cosmological time dilation yet, White says, up to seven times more precise than previous measurements of cosmological time dilation that used fewer supernovae. [...] This particular supernova-focused facet of the Dark Energy Survey has concluded, so until a new dataset is taken, White's measurement of cosmological time dilation is unlikely to be beaten. "It's a pretty definitive measurement," says [Tamara Davis of the University of Queensland, a co-author of the paper]. "You don't really need to do any better."

An anonymous reader quotes a report from TechCrunch: A hacker is advertising customer data allegedly stolen from the Australia-based live events and ticketing company TEG on a well-known hacking forum. On Thursday, a hacker put up for sale the alleged stolen data from TEG, claiming to have information of 30 million users, including the full name, gender, date of birth, username, hashed passwords, and email addresses. In late May, TEG-owned ticketing company Ticketek disclosed a data breach affecting Australian customers' data, "which is stored in a cloud-based platform, hosted by a reputable, global third party supplier."

The company said that "no Ticketek customer account has been compromised," thanks to the encryption methods used to store their passwords. TEG conceded, however, that "customer names, dates of birth and email addresses may have been impacted" -- data that would line up with that advertised on the hacking forum. The hacker included a sample of the alleged stolen data in their post. TechCrunch confirmed that at least some of the data published on the forum appears legitimate by attempting to sign up for new accounts using the published email addresses. In a number of cases, Ticketek's website gave an error, suggesting the email addresses are already in use. There's evidence that the company's "cloud-based platform" provider is Snowflake, "which has been at the center of a recent series of data thefts affecting several of its customers, including Ticketmaster, Santander Bank, and others," notes TechCrunch.

"A now-deleted post on Snowflake's website from January 2023 was titled: 'TEG Personalizes Live Entertainment Experiences with Snowflake.' In 2022, consulting company Altis published a case study (PDF) detailing how the company, working with TEG, 'built a modern data platform for ingesting streaming data into Snowflake.'"

Apple has announced visionOS 2 for its Vision Pro spatial computing headset, bringing mouse support, an ultrawide virtual Mac display option, and new Photo features. The company says it's expected to launch "later this year." The Verge reports: The most significant update, for all the productivity heads out there, is a new ultrawide virtual display feature. Apple says that in visionOS 2, you'll be able to connect a Vision Pro to a Mac to generate a dual 4K-equivalent curved ultrawide display. Right now, the virtual display feature only does a single up to 5K one. Also, the company will finally add mouse support to the Vision Pro -- at launch, the headset could work with trackpads like the one on a MacBook Air or the standalone Magic Trackpad 2, but oddly left out mouse support. You can still use one inside a mirrored display in the Vision Pro, but not outside of that screen in, say, an iPad or Vision Pro app.

Apple says that in the new update, users will be able to convert any image in the Photos app to a spatial one. Also, visionOS 2 will have train support, so the Vision Pro's travel mode will no longer be limited to just airplanes. The company also says it's adding SharePlay to the visionOS Photos app, which means that you can share the app with another Vision Pro owner using Spatial Personas [...]. The company says Red Bull is making a new immersive sports series, while Apple is making its first scripted immersive feature. Apple also said that Canon is releasing a new spatial lens for the EOS R7, one designed specifically for creating content for the Vision Pro.

Finally, the company is rolling out the Vision Pro abroad. Apple is going to start taking preorders in China, Hong Kong, Japan, and Singapore on June 13th at 6PM PT, and it'll be available in those countries on June 28th. Australia, Canada, France, Germany, and the UK will get preorders later, on June 28th at 5AM PT, with the headset officially available on July 12th.

An anonymous reader quotes a report from New Atlas: The universe is awash with strange radio signals, but astronomers have now detected a really bizarre one that repeats every hour, cycling through three different states. While they have some ideas about its origin it can't be explained by our current understanding of physics. The signal first appeared in data gathered by the ASKAP radio telescope in Australia, which watches a big swath of sky at once for transient pulses. Officially designated ASKAP J1935+2148, the signal seems to repeat every 53.8 minutes. Whatever it is, the signal cycles through three different states. Sometimes it shoots out bright flashes that last between 10 and 50 seconds and have a linear polarization, meaning the radio waves all "point" in the same direction. Other times, its pulses are much weaker with a circular polarization, lasting just 370 milliseconds. And sometimes, the object misses its cue and stays silent.

So what could be behind such a weird radio signal? Let's get it out of the way up front: it's not aliens (probably). The most likely explanation, according to the scientists who discovered it, is that it's coming from a neutron star or a white dwarf. But it's not a neat solution, since the signal's weird properties don't fit with our understanding of the physics of those two kinds of objects. Neutron stars and white dwarfs are fairly similar, but with some key differences. They're both born from the deaths of bigger stars, with the original mass dictating whether you end up with a neutron star or a white dwarf. Neutron stars are known to blast radio waves out regularly, so they're a prime suspect here. It's possible that signals this varied could be produced by interactions between their strong magnetic fields and complex plasma flows. But there's a major problem: they usually spin at speeds of seconds or fractions of a second per revolution. It should be physically impossible for one to spin as slow as once every 54 minutes. White dwarfs, on the other hand, would have no problem spinning that slowly, but as the team says, "we don't know of any way one could produce the radio signals we are seeing here." "It might even prompt us to reconsider our decades-old understanding of neutron stars or white dwarfs; how they emit radio waves and what their populations are like in our Milky Way galaxy," added Caleb.

The findings have been published in the journal Nature Astronomy.

An anonymous reader quotes a report from the New York Times: Last year, Jaume Pellicer led a team of fellow scientists into a forest on Grande Terre, an island east of Australia. They were in search of a fern called Tmesipteris oblanceolata. Standing just a few inches tall, it was not easy to find on the forest floor. "It doesn't catch the eye," said Dr. Pellicer, who works at the Botanical Institute of Barcelona in Spain. "You would probably step on it and not even realize it." The scientists eventually managed to spot the nondescript fern. When Dr. Pellicer and his colleagues studied it in the lab, they discovered it held an extraordinary secret. Tmesipteris oblanceolata has the largest known genome on Earth. As the researchers described in a study published on Friday, the fern's cells contain more than 50 times as much DNA as ours do. [The analysis revealed the species T. oblanceolata to have a record-breaking genome size of 160.45 Gbp, which is about 7% larger than that of P. japonica (148.89 Gbp). For comparison, the human genome contains about 3.1 Gbp distributed across 23 chromosomes and when stretched out like a ball of yarn, the length of DNA in each cell only measures about 2m.] "Surprisingly, having a larger genome is usually not an advantage," notes Phys.org in a report. "In the case of plants, species possessing large amounts of DNA are restricted to being slow growing perennials, are less efficient at photosynthesis (the process by which plants convert the sun's energy into sugars) and require more nutrients (especially nitrogen and phosphates) to grow and compete successfully with their smaller-genomed neighbors. In turn, such effects may influence the ability of a plant to adapt to climate change and their risk of extinction."

"In animals, some of the largest genomes include the marbled lungfish (Protopterus aethiopicus) at 129.90 Gbp and the Neuse River waterdog (Necturus lewisi) at 117.47 Gbp," reports Phys.org. "In stark contrast, six of the largest-known eukaryotic genomes are held by plants, including the European mistletoe (Viscum album) at 100.84 Gbp."
