Apple is challenging a new Indian antitrust law that would let regulators calculate penalties based on global revenue -- a change that could expose the company to a fine of roughly $38 billion in its dispute with Tinder owner Match. The 2022 antitrust case centers on accusations that Apple abused its power by forcing developers to use its in-app purchase system. MacRumors reports: Last year, India passed a law that allows the Competition Commission of India (CCI) to use global turnover when calculating penalties imposed on companies for abusing market dominance. Apple can be fined up to 10 percent, which would result in a penalty of around $38 billion. Apple said that using global turnover would result in a fine that's "manifestly arbitrary, unconstitutional, grossly disproportionate, and unjust."

Apple is asking India's Delhi High Court to declare the law illegal, suggesting that penalties should be based on the Indian revenue of the specific unit that violates antitrust law. [...] Apple said in today's filing that the CCI used the new penalty law on November 10 in an unrelated case, fining a company for a violation that happened 10 years ago. Apple said it had "no choice but to bring this constitutional challenge now" to avoid having retrospective penalties applied against it, too. Match has argued that a high fine based on global turnover would discourage companies from repeating antitrust violations. Apple's plea will be heard on December 3.

China's new JUNO neutrino observatory has delivered world-leading measurements after just 59 days, offering the most precise readings yet of two key neutrino oscillation parameters. "The physics result is already world-leading in the areas that it touches," says particle physicist Juan Pedro Ochoa-Ricoux of the University of California, Irvine, who co-leads a team on JUNO. "In particular, we measured two neutrino oscillation parameters, and that measurement is already for both parameters the best in the world." The results were published in two separate preprints on arXiv.org. Scientific American reports: JUNO's spherical detector, which is akin to a 13-story-tall fishbowl, primarily measures so-called electron antineutrinos spewing from the nearby Yangjian and Taishan nuclear plants. When the particles strike a proton inside the detector, a reaction triggers two light flashes that ping photomultiplier tubes and get converted into electrical signals. The new measurements from these neutrino-proton collisions are now considered the most precise for two oscillation parameters, which act as proxies for differences in their mass, according to Ochoa-Ricoux.

"It is the first time we've turned on a scientific instrument like JUNO that we've been working on for over a decade. It's just tremendously exciting," Ochoa-Ricoux says. "And then to see that we're able to already do world-leading measurements with it, even with such a small amount of data, that's also really exciting." Still, the physicists will need years' worth of neutrino detections to answer the mass-ordering conundrum.

An anonymous reader quotes a report from the Associated Press: Mexico unveiled plans Wednesday to build what it claims will be Latin America's most powerful supercomputer -- a project the government says will help the country capitalize on the rapidly evolving uses of artificial intelligence and exponentially expand the country's computing capacity. Dubbed "Coatlicue" for the Mexica goddess considered the earth mother, the supercomputer would be seven times more powerful than the region's current leader in Brazil, Jose Merino, head of the Telecommunications and Digital Transformation Agency.

President Claudia Sheinbaum said during her morning news briefing that the location for the project had not been decided yet, but construction will begin next year. "We're very excited," said Sheinbaum, an academic and climate scientist. "It is going to allow Mexico to fully get in on the use of artificial intelligence and the processing of data that today we don't have the capacity to do." Merino said that Mexico's most powerful supercomputer operates at 2.3 petaflops -- a unit to measure computing speed, meaning it can perform one quadrillion operations per second. Coatlicue would have a capacity of 314 petaflops.
