Submission + - Scientists Reveal Roof Coating That Can Reduce Surface Temps 6C On Hot Days (theguardian.com)

An anonymous reader writes: Australian scientists have developed roof coatings that can passively cool surfaces up to 6C below ambient temperature, as well as extract water from the atmosphere, which they say could reduce indoor temperatures during extreme heat events. One coating made from a porous film, which can be painted on to existing roofs, works by reflecting 96% of incoming solar radiation, rather than absorbing the sun’s energy. It also has a high thermal emittance, meaning it effectively dissipates heat to outer space when the sky is clear. Its properties are known as passive radiative cooling. [...]

In a study, published in the journal Advanced Functional Materials, the researchers tested a prototype for six months on the roof of the Sydney Nanoscience Hub, pairing the cool paint with a UV-resistant topcoat that encouraged dew droplets to roll down into a receptacle. As much as 390 milliliters per sq meter per day could be collected for about a third of the year, the scientists found. Based on that water capture rate, an average Australian roof – about 200 sq meters – could provide up to 70 liters on days favorable for collecting dew, they estimate. [...]

In well-insulated buildings, a 6C decrease in roof temperature “might result in a smaller fraction of that cooling being reflected in the top level of the house," [said the study’s lead author, Prof Chiara Neto of the University of Sydney], but greater temperature reductions would be expected in most Australian houses, “where insulation is quite poor." She said the coating could also help reduce the urban heat island effect, in which hard surfaces absorb more heat than natural surfaces, resulting in urban centers being 1C to 13C warmer than rural areas.

Submission + - Someone Snuck Into a Cellebrite Microsoft Teams Call and Leaked Phone Unlocking (404media.co)

An anonymous reader writes: Someone recently managed to get on a Microsoft Teams call with representatives from phone hacking company Cellebrite, and then leaked a screenshot of the company’s capabilities against many Google Pixel phones, according to a forum post about the leak and 404 Media’s review of the material. The leak follows others obtained and verified by 404 Media over the last 18 months. Those leaks impacted both Cellebrite and its competitor Grayshift, now owned by Magnet Forensics. Both companies constantly hunt for techniques to unlock phones law enforcement have physical access to.

“You can Teams meeting with them. They tell everything. Still cannot extract esim on Pixel. Ask anything,” a user called rogueFed wrote on the GrapheneOS forum on Wednesday, speaking about what they learned about Cellebrite capabilities. GrapheneOS is a security- and privacy-focused Android-based operating system. rogueFed then posted two screenshots of the Microsoft Teams call. The first was a Cellebrite Support Matrix, which lays out whether the company’s tech can, or can’t, unlock certain phones and under what conditions. The second screenshot was of a Cellebrite employee. According to another of rogueFed’s posts, the meeting took place in October. The meeting appears to have been a sales call. The employee is a “pre sales expert,” according to a profile available online.

The Support Matrix is focused on modern Google Pixel devices, including the Pixel 9 series. The screenshot does not include details on the Pixel 10, which is Google’s latest device. It discusses Cellebrite’s capabilities regarding ‘before first unlock’, or BFU, when a piece of phone unlocking tech tries to open a device before someone has typed in the phone’s passcode for the first time since being turned on. It also shows Cellebrite’s capabilities against after first unlock, or AFU, devices. The Support Matrix also shows Cellebrite’s capabilities against Pixel devices running GrapheneOS, with some differences between phones running that operating system and stock Android. Cellebrite does support, for example, Pixel 9 devices BFU. Meanwhile the screenshot indicates Cellebrite cannot unlock Pixel 9 devices running GrapheneOS BFU. In their forum post, rogueFed wrote that the “meeting focused specific on GrapheneOS bypass capability.” They added “very fresh info more coming.”

Submission + - Israel Demanded Google and Amazon Use Secret 'Wink' To Sidestep Legal Orders (theguardian.com) 1

An anonymous reader writes: When Google and Amazon negotiated a major $1.2bn cloud-computing deal in 2021, their customer – the Israeli government – had an unusual demand: agree to use a secret code as part of an arrangement that would become known as the “winking mechanism." The demand, which would require Google and Amazon to effectively sidestep legal obligations in countries around the world, was born out of Israel’s concerns that data it moves into the global corporations’ cloud platforms could end up in the hands of foreign law enforcement authorities.

Like other big tech companies, Google and Amazon’s cloud businesses routinely comply with requests from police, prosecutors and security services to hand over customer data to assist investigations. This process is often cloaked in secrecy. The companies are frequently gagged from alerting the affected customer their information has been turned over. This is either because the law enforcement agency has the power to demand this or a court has ordered them to stay silent. For Israel, losing control of its data to authorities overseas was a significant concern. So to deal with the threat, officials created a secret warning system: the companies must send signals hidden in payments to the Israeli government, tipping it off when it has disclosed Israeli data to foreign courts or investigators.

To clinch the lucrative contract, Google and Amazon agreed to the so-called winking mechanism, according to leaked documents seen by the Guardian, as part of a joint investigation with Israeli-Palestinian publication +972 Magazine and Hebrew-language outlet Local Call. Based on the documents and descriptions of the contract by Israeli officials, the investigation reveals how the companies bowed to a series of stringent and unorthodox “controls” contained within the 2021 deal, known as Project Nimbus. Both Google and Amazon’s cloud businesses have denied evading any legal obligations.

Submission + - US Declines To Join More Than 70 Countries In Signing UN Cybercrime Treaty (therecord.media)

An anonymous reader writes: More than 70 countries signed the landmark U.N. Convention against Cybercrime in Hanoi this weekend, a significant step in the yearslong effort to create a global mechanism to counteract digital crime. The U.K. and European Union joined China, Russia, Brazil, Nigeria and dozens of other nations in signing the convention, which lays out new mechanisms for governments to coordinate, build capacity and track those who use technology to commit crimes. [...]

While many countries did not sign the treaty, the most notable missing signature was that of the U.S. “The United States continues to review the treaty,” a State Department spokesperson said in a brief statement. The U.N. Convention against Cybercrime was adopted by the General Assembly in December 2024 and will enter into force 90 days after being ratified by the 40th signatory. Signatories will have to ratify the convention according to their own procedures.

[...] U.N. officials said the convention would help governments address terrorism, human trafficking, money laundering and drug smuggling, all of which have been turbo-charged by the internet. The U.N. noted that the convention is the first global framework “for the collection, sharing and use of electronic evidence for all serious offenses” — noting that until now there have been no broadly accepted international standards on electronic evidence. It is also the first global treaty to criminalize crimes that depend on the internet and is the first international treaty “to recognize the non-consensual dissemination of intimate images as an offense.”

Submission + - Our Brains React Differently to Deepfake Voices

jenningsthecat writes: University of Zurich researchers have discovered that our brains process natural human voices and "deepfake" voices differently:

The researchers first used psychoacoustical methods to test how well human voice identity is preserved in deepfake voices. To do this, they recorded the voices of four male speakers and then used a conversion algorithm to generate deepfake voices. In the main experiment, 25 participants listened to multiple voices and were asked to decide whether or not the identities of two voices were the same. Participants either had to match the identity of two natural voices, or of one natural and one deepfake voice.
The deepfakes were correctly identified in two thirds of cases. “This illustrates that current deepfake voices might not perfectly mimic an identity, but do have the potential to deceive people,” says Claudia Roswandowitz, first author and a postdoc at the Department of Computational Linguistics...
The researchers then used imaging techniques to examine which brain regions responded differently to deepfake voices compared to natural voices. They successfully identified two regions that were able to recognize the fake voices: the nucleus accumbens and the auditory cortex. “The nucleus accumbens is a crucial part of the brain’s reward system. It was less active when participants were tasked with matching the identity between deepfakes and natural voices,” says Claudia Roswandowitz. In contrast, the nucleus accumbens showed much more activity when it came to comparing two natural voices.

The complete paper appears in Nature.

Submission + - Satellite 'Megaconstellations' May Jeopardize Recovery of Ozone Hole (phys.org)

An anonymous reader writes: When old satellites fall into Earth's atmosphere and burn up, they leave behind tiny particles of aluminum oxide, which eat away at Earth's protective ozone layer. A new study finds that these oxides have increased 8-fold between 2016 and 2022 and will continue to accumulate as the number of low-Earth-orbit satellites skyrockets. The 1987 Montreal Protocol successfully regulated ozone-damaging CFCs to protect the ozone layer, shrinking the ozone hole over Antarctica with recovery expected within fifty years. But the unanticipated growth of aluminum oxides may push pause on the ozone success story in decades to come. Of the 8,100 objects in low Earth orbit, 6,000 are Starlink satellites launched in the last few years. Demand for global internet coverage is driving a rapid ramp up of launches of small communication satellite swarms. SpaceX is the frontrunner in this enterprise, with permission to launch another 12,000 Starlink satellites and as many as 42,000 planned. Amazon and other companies around the globe are also planning constellations ranging from 3,000 to 13,000 satellites, the authors of the study said. Internet satellites in low Earth orbit are short-lived, at about five years. Companies must then launch replacement satellites to maintain internet service, continuing a cycle of planned obsolescence and unplanned pollution.

Aluminum oxides spark chemical reactions that destroy stratospheric ozone, which protects Earth from harmful UV radiation. The oxides don't react chemically with ozone molecules, instead triggering destructive reactions between ozone and chlorine that deplete the ozone layer. Because aluminum oxides are not consumed by these chemical reactions, they can continue to destroy molecule after molecule of ozone for decades as they drift down through the stratosphere. Yet little attention has yet been paid to pollutants formed when satellites fall into the upper atmosphere and burn. Earlier studies of satellite pollution largely focused on the consequences of propelling a launch vehicle into space, such as the release of rocket fuel. The new study, by a research team from the University of Southern California Viterbi School of Engineering, is the first realistic estimate of the extent of this long-lived pollution in the upper atmosphere, the authors said. [...]

In 2022, reentering satellites increased aluminum in the atmosphere by 29.5% over natural levels, the researchers found. The modeling showed that a typical 250-kilogram (550-pound) satellite with 30% of its mass being aluminum will generate about 30 kilograms (66 pounds) of aluminum oxide nanoparticles (1-100 nanometers in size) during its reentry plunge. Most of these particles are created in the mesosphere, 50-85 kilometers (30-50 miles) above Earth's surface. The team then calculated that based on particle size, it would take up to 30 years for the aluminum oxides to drift down to stratospheric altitudes, where 90% of Earth's ozone is located. The researchers estimated that by the time the currently planned satellite constellations are complete, every year, 912 metric tons of aluminum (1,005 U.S. tons) will fall to Earth. That will release around 360 metric tons (397 U.S. tons) of aluminum oxides per year to the atmosphere, an increase of 646% over natural levels.

Submission + - Asda IT Staff Shuffled Off To TCS Amid Messy Tech Divorce From Walmart (theregister.com)

An anonymous reader writes: Asda is transferring more than 100 internal IT workers to Indian outsourcing company TCS as it labors to meet deadlines to move away from IT systems supported by previous owner Walmart by the end of the year. According to documents seen by The Register, a collective consultation for a staff transfer under TUPE – an arrangement by which employment rights are protected under UK law – begins today (June 17). The UK's third-largest supermarket expects affected staff to meet line managers from June 24, while the transfer date is set for September 16. Contractors will be let go at the end of their current contracts. Asda employs around 5,000 staff in its UK offices. Between 130 and 135 members of the IT team have entered the collective consultation to move to TCS.

The move came as private equity company TDR Capital gained majority ownership of the supermarket group. It was acquired from Walmart by the brothers Mohsin and Zuber Issa and TDR Capital in February 2021 at a value of 6.8 billion pounds. The US retail giant retained "an equity investment." Project Future is a massive shift in the retailer's IT function. It is upgrading a legacy ERP system from SAP ECC – run on-prem by Walmart – to the latest SAP S/4HANA in the Microsoft Azure cloud, changing the application software, infrastructure, and business processes at the same time. Other applications are also set to move to Azure, including ecommerce and store systems, while Asda is creating an IT security team for the first time – the work had previously been carried out by its US owner.

Asda signed up to SAP's "RISE" program in a deal to lift, shift, and transform its ERP system – a vital plank in the German vendor's strategy to get customers to the cloud – in December 2021. But the project has already been beset by delays. The UK retailer had signed a three-year deal with Walmart in February 2021 to continue to support its existing system, but was forced to renegotiate to extend the arrangement, saying it planned to move away from the legacy systems before the end of 2024. Although one insider told El Reg that deadline was "totally unachievable," the Walmart deal extends to September 2025, giving the UK retailer room to accommodate further delays without renegotiating the contract.

Asda has yet to migrate a single store to the new infrastructure. The first – Yorkshire's Otley – is set to go live by the end of June. One insider pointed out that project managers were trying to book resources from the infrastructure team for later this year and into the next, but, as they were set to transfer to TCS, the infrastructure team did not know who would be doing the work or what resources would be available. "They have a thousand stores to migrate and they're going to be doing that with an infrastructure team who have their eyes on the door. They'll be very professional, but they're not going above and beyond and doing on-call they don't have to do," the insider said.

Submission + - KDE Plasma 6.1 released (kde.org)

jrepin writes: The KDE community announces the latest release of their popular desktop environment: Plasma 6.1 . While Plasma 6.0 was all about getting the migration to the underlying Qt 6 frameworks correct, Plasma 6.1 is where developers start implementing the features that will take you desktop to a new level. In this release, you will find features that go far beyond subtle changes to themes and tweaks to animations (although there is plenty of those too). Among some of the new features in this release you will find improved remote desktop support with a new built-in server, overhauled and streamlined desktop edit mode, restoration of open applications from the previous session on Wayland, synchronization of keyboard LED colors with the desktop accent color, making mouse cursor bigger and easier to find by shaking it, edge barriers (a sticky area for mouse cursor near the edges between screens), explicit sync support eliminates flickering and glitches for NVidia graphics card users on Wayland, and triple buffering support for smoother animations and screen rendering. For detailed information see the KDE Plasma 6.1 release announcement.

Submission + - Ukraine turning to AI to prioritise 700 years of landmine removal (newscientist.com)

MattSparkes writes: The Russian invasion of Ukraine has seen so many landmines deployed across the country that clearing them would take 700 years, say researchers. To make the task more manageable, Ukrainian scientists are turning to artificial intelligence to identify which regions are a priority for de-mining, though they expect some may simply have to be left as a permanent “scar” on the country.

The model considers vast amounts of data, including tax and property ownership records, agricultural maps, data on soil fertility, logs from the military and emergency services of where bombs and shells have landed, information gleaned from satellite images and interviews with local civilians and the military. Even climate change models and data on population density derived from mobile phone operators could be assessed. The AI then weighs factors such as civilian safety and potential economic benefits to determine the importance of a given piece of land and how urgent it is to make it safe.

Ihor Bezkaravainyi, a deputy minister at Ukraine’s Ministry of Economy, is leading the team, and he likens the task of de-mining during an ongoing war to designing and building a submarine entirely underwater, except that the water is on fire. “It’s a big problem,” he says.

Submission + - London Underground Hosts Tests For 'Quantum Compass' That Could Replace GPS (theguardian.com)

An anonymous reader writes: Dr Joseph Cotter takes some unusual pieces of luggage on his trips on the London underground. They include a stainless steel vacuum chamber, a few billion atoms of rubidium and an array of lasers that are used to cool his equipment to a temperature just above absolute zero. While not the average kit you would expect to find being dragged into carriages on the District Line, this is the gear that Cotter – who works at Imperial College London’s Centre for Cold Matter – uses on his underground travels. Though the baggage may be bizarre, it has an ambitious purpose. It is being used to develop a quantum compass – an instrument that will exploit the behavior of subatomic matter in order to develop devices that can accurately pinpoint their locations no matter where they are placed, paving the way for the creation of a new generation of underground and underwater sensors. The ideal place to test it is the London underground, Cotter and his team have discovered. “We are developing very precise new sensors using quantum mechanics, and these are showing great promise in the laboratory,” he told the Observer last week. “However, they are less accurate in real-life settings. That is why we are taking our equipment to the London underground. It’s the perfect place for smoothing out the rough edges and getting our equipment to work in real life." [...]

At the heart of the quantum compass – which could be ready for widespread use in a few years – is a device known as an accelerometer that can measure how an object’s velocity changes over time. This information, combined with the starting point of that object, allows its future positions to be calculated. Mobile phones and laptops possess accelerometers but these versions cannot maintain their accuracy over lengthy periods. However, quantum mechanics offers scientists a way to provide new precision and accuracy by measuring properties of supercool atoms. At extremely low temperatures, atoms behave in a “quantum” way. They act like matter and like waves. “When atoms are ultra-cold, we can use quantum mechanics to describe how they move, and this allows us to make accurate measurements that tell us how our device is changing its position,” said Cotter. In the devices – which have been carried on board London underground track-testing trains and not on commuter services – rubidium is inserted into the vacuum chamber that lies at the machine’s heart. Powerful lasers are then used to cool these atoms to a fraction of a degree above absolute zero (-273.15C). In these conditions, the wave properties of the rubidium atoms are affected by the acceleration of the vehicle that is carrying the equipment, and these minute changes can be measured accurately. The system has been found to work well in a stable laboratory but needs to be tested in more extreme conditions if it is to be turned into a transportable, standalone device that can be used in remote or complex locations, added Cotter.

Submission + - Google, Cloudflare & Cisco Will Poison DNS to Stop Piracy Block Circumventio (torrentfreak.com) 1

couchslug writes: A French court has ordered Google, Cloudflare, and Cisco to poison their DNS resolvers to prevent circumvention of blocking measures, targeting around 117 pirate sports streaming domains. The move is another anti-piracy escalation for broadcaster Canal+, which also has permission to completely deindex the sites from search engine results.

Stopping someone from acting is not the same as censoring what others may see via search engines. If this becomes a common resort it could be applied to much more than streaming sites.
