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.

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.
