EU Commission appeals after losing Apple $15B tax case

EU Commission appeals after losing Apple $15B tax case

September 25, 2020The European Commission said Friday it is appealing a court decision that Apple doesn't have to repay 13 billion euros ($15 billion) in back taxes to Ireland.The appeal comes after the U.S. tech giant scored a big recent legal victory in its long battle with the European Union's executive Commission, which has been trying to rein in multinationals' ability to strike special tax deals with individual EU countries.The EU's General Court ruled that the commission wrongly declared in 2016 that Apple was given illegal state aid when it struck a low tax rate agreement with Irish...

Did I leave the stove on? Amazon's flying camera can check

September 25, 2020by Joseph PisaniAmazon wants to be able to answer the nagging question: Did I leave the stove on?The company unveiled a flying home that you can ask to fly to check the stove while you're out, or to see if you left the windows open. Amazon says the drone will automatically take flight if there's movement in the house to show you what's going on.The device was one of several that Amazon unveiled Thursday as part of its annual gadget event. Due to the pandemic, this year's version was held online instead of at Amazon's Seattle headquarters.The indoor flying camera, called...

California is ready to pull the plug on gas vehicles

September 23, 2020by Adam BeamCalifornia will ban the sale of new gasoline-powered passenger cars and trucks in 15 years, Gov. Gavin Newsom announced Wednesday, establishing a timeline in the nation's most populous state that could force U.S. automakers to shift their zero-emission efforts into overdrive.The plan won't stop people from owning gas-powered cars or selling them on the used car market. But in 2035 it would end the sale of all new such vehicles in the state of nearly 40 million people that accounts for more than one out of every 10 new cars sold in the U.S.California would be...

Microsoft turns to holographic solutions for cloud storage

September 24, 2020by Peter Grad , Tech XploreWhen people think of holograms, they may think of the small insignia on credit cards that appear to move as you rotate the card. Or they may think of recent rock concert spectacles featuring realistic 3-D performances by singers who are no longer alive. Whitney Houston, Roy Orbison, Tupac Shakur, Buddy Holly and Ronnie James Dio drew rave reviews from fans in 'live' performances made possible by holography even though they all have been dead for years.Holograms consist of a series of special types of image created by laser using diffraction to...

Engineers pre-train AI computers to make them even more powerful

September 22, 2020by Swiss Center for Electronics and Microtechnology - CSEMEngineers at CSEM have developed a new machine-learning method that paves the way for artificial intelligence to be used in applications that until now have been deemed too sensitive. The method, which has been tested by running simulations on a climate-control system for a 100-room building, is poised to deliver energy savings of around 20%.In 2016, a supercomputer beat the world champion in Go, a complicated board game. How? By using reinforcement learning, a type of whereby computers train themselves after being...

Oceanbird cargo ship relies on wind to transport autos

September 18, 2020by Peter Grad , Tech XploreThe latest trend in cargo shipping has roots in a concept that's been around a while. Say, 7,000 years or so.The technology is the wind, and the tool is the sailboat. First depicted on an unearthed painted disc in Kuwait believed to have been created around 5,000 BC, sailboats have played a key role in discovery, adventure, conflict and commerce.

US gives first-ever OK for small commercial nuclear reactor

U.S. officials have for the first time approved a design for a small commercial nuclear reactor, and a Utah energy cooperative wants to build 12 of them in Idaho. The U.S. Nuclear Regulatory Commission on Friday approved Portland-based NuScale Power's application for the small modular reactor that Utah Associated Municipal Power Systems plans to build at a U.S. Department of Energy site in eastern Idaho. The small reactors can produce about 60 megawatts of energy, or enough to power more than 50,000 homes. The proposed project includes 12 small modular reactors. The first would be built...
