InfiniteZero shares a report from Phys.Org: Did our sun have a twin when it was born 4.5 billion years ago? Almost certainly yes -- though not an identical twin. And so did every other sun-like star in the universe, according to a new analysis by a theoretical physicist from UC Berkeley and a radio astronomer from the Smithsonian Astrophysical Observatory at Harvard University. The new assertion is based on a radio survey of a giant molecular cloud filled with recently formed stars in the constellation Perseus, and a mathematical model that can explain the Perseus observations only if all sunlike stars are born with a companion. "We ran a series of statistical models to see if we could account for the relative populations of young single stars and binaries of all separations in the Perseus molecular cloud, and the only model that could reproduce the data was one in which all stars form initially as wide (more than 500 astronomical units) binaries," said co-author Steven Stahler, a UC Berkeley research astronomer. "These systems then either shrink or break apart within a million years." The study has been published in April on the arXiv server.

The federal government will finally stop preparing for the Y2K bug, seventeen years after it came and went. Yes, you read that right. Bloomberg reports: The Trump administration announced Thursday that it would eliminate dozens of paperwork requirements for federal agencies, including an obscure rule that requires them to continue providing updates on their preparedness for a bug that afflicted some computers at the turn of the century. As another example, the Pentagon will be freed from a requirement that it file a report every time a small business vendor is paid, a task that consumed some 1,200 man-hours every year. Seven of the more than 50 paperwork requirements the White House eliminated on Thursday dealt with the Y2K bug, according to a memo OMB released. Officials at the agency estimate the changes could save tens of thousands of man-hours across the federal government. The agency didn't provide an estimate of how much time is currently spent on Y2K paperwork, but Linda Springer, an OMB senior adviser, acknowledged that it isn't a lot since those requirements are already often ignored in practice.

A Canadian expedition to study climate change in the Arctic has been canceled due to climate change. Specifically, the icebreaker CCGS Amundsen had to be cancelled "due to complications associated with the southward motion of hazardous Arctic sea ice," reports University of Manitoba. From the report: This regrettably postpones the much-anticipated Hudson Bay System Study (BaySys) involving 40 scientists from five universities across Canada. Timing was key for this $17 million, four-year, University of Manitoba-led project. The need to deal with extreme ice conditions in the south meant the ship would arrive too late on site to meet research objectives. This year the Expedition Logistics and Science Teams accelerated the mobilization of the 2017 Arctic Expedition to permit departure of the Amundsen six days ahead of schedule. This would allow CCG to carry out critical marine safety and security operations in the unusually severe ice conditions in the Strait of Belle Isle and along the northeast coast of Newfoundland before beginning the Science Mission. Unfortunately, the conditions required much more extended support than anticipated. Fleet management issues and inadequate alternative ships forced the cancellation of the science program due to significant safety concerns. This decision to cancel the BaySys 2017 program was not made lightly. Although the cancellation was due to circumstances beyond control of the Expedition Team, every effort was made to develop a viable option to allow this valuable work to proceed.

The U.S. Department of Energy will be investing $258 million to help six leading technology firms -- AMD, Cray Inc., Hewlett Packard Enterprise, IBM, Intel, and Nvidia -- research and build exascale supercomputers. Digital Trends reports: The funding will be allocated to them over the course of a three-year period, with each company providing 40 percent of the overall project cost, contributing to an overall investment of $430 million in the project. "Continued U.S. leadership in high performance computing is essential to our security, prosperity, and economic competitiveness as a nation," U.S. Secretary of Energy Rick Perry said. "These awards will enable leading U.S. technology firms to marshal their formidable skills, expertise, and resources in the global race for the next stage in supercomputing -- exascale-capable systems." The funding will finance research and development in three key areas; hardware technology, software technology, and application development. There are hopes that one of the companies involved in the initiative will be able to deliver an exascale-capable supercomputer by 2021.

An anonymous reader writes: After a two-week hiatus, WikiLeaks dumped new files as part of the Vault 7 series -- documents about a CIA tool named CherryBlossom, a multi-purpose framework developed for hacking hundreds of home router models. The tool is by far one of the most sophisticated CIA malware frameworks in the CIA's possession. The purpose of CherryBlossom is to allow operatives to interact and control SOHO routers on the victim's network. The tool can sniff, log, and redirect the user's Internet traffic, open a VPN to the victim's local network, execute actions based on predefined rules, alert operators when the victim becomes active, and more. A 24-page document included with the CherryBlossom docs lists over 200 router models from 21 vendors that the CIA could hack. The biggest names on this list are Apple, D-Link, Belkin, Aironet (Cisco), Linksys, and Motorola.

Joe Rossignol reports via Mac Rumors: Spotify today announced it now has over 140 million subscribers worldwide, including users that only listen to the free ad-supported tier. Spotify last said it had over 100 million subscribers in June 2016, so it has gained around 40 million listeners in one year to remain the world's largest streaming music service. Spotify didn't update its number of paying subscribers, which stood at over 50 million worldwide as of March 2017. By comparison, Apple at its Worldwide Developers Conference last week announced that Apple Music now has 27 million paying subscribers, just weeks before the streaming music service turns two years old. Apple Music doesn't have a free tier, and Apple doesn't regularly disclose how many users are using the free trial.

An anonymous reader quotes a report from KNKX: If you live in Washington state, you might have gotten the email from eBay. It begins: "The Washington State Legislature is threatening to impose new Internet sales tax burdens on you." It goes on to urge the recipient to send a form letter to Washington lawmakers opposing "harmful tax laws." So what's this about? EBay's Brian Bieron said the company is alerting its customers to a proposal to require out-of-state retailers to collect sales tax from Washington residents. "It's the right of all of our users to know when new tax policies would impact their ability to sell online or shop online, we think that they want to know and they want to get involved," Bieron said. The fact eBay is emailing its customer base now indicates the company is concerned the internet tax bill will be part of a final budget deal in Olympia. Washington House Democrats and Senate Republicans are currently trying to hash out a compromise budget that fully fund schools. That agreement will likely include some additional sources of tax revenue. Of all the choices on the table, capturing sales tax from more online sales might prove the most palatable to tax-averse Republicans. House Democrats estimate the proposal could bring in an estimated $341 million over the next two years.
