The US and China have been locked in a race for the world's most powerful supercomputer. China was in the lead with its Sunway TaihuLight, which has a 93 petaflop capacity. But the US surpassed that last year, when it released the Summit, which can run at 200 petaflops -- or 200 quadrillion calculations per second.

Tech industry executives for years have promised that drones -- aircraft vehicles that operate without a pilot on board -- are the future of delivery. The small, buzzy aircraft have increasingly emerged in the skies above U.S. cities, dropping products including food and medical supplies at or near peoples’ doorsteps.  But mainstream implementation of drone delivery services is likely still years off...

Members of the Senate Commerce security subcommittee examined the impact of banning Chinese-made drones, or components for drones, during a hearing on Tuesday. The senators compared the debate on drones to the recent decision by the Department of Commerce to blacklist Chinese telecommunications giant Huawei in May, a move that barred U.S. firms from working with the company.

If you’re a consumer, the 5G horizon seems to be getting closer by the day as vendors begin shipping 5G-capable handsets and telecom operators refine their buildout plans. But as the pace gradually quickens, one thing is clear: The transition to 5G won’t look anything like 3G and 4G migrations. To a certain extent, 5G will expand the speed-and-performance curve just as 3G and 4G did. And sure, we’ll have fancy new 5G phones in a couple of years, but we’re not where the real action is going to be. Because this isn’t going to be a consumer revolution at all.

The effective diameter of the Terahertz Space Telescope, Walker says, would be about 25 meters. To put this in perspective, the James Webb Space Telescope--which is slated to launch in 2021, and will be the most sensitive telescope ever sent to space--has an aperture of about 6.5 meters. The price difference is even more dramatic: Walker estimates the inflatable telescope would cost around $200 million to send to orbit, whereas the James Webb telescope is expected to cost about $10 billion by the time it’s launched.

Virginia Tech is building its newest campus in the city of Alexandria, Virginia, just south of the planned location of Amazon’s site in Arlington. Virginia Tech President Tim Sands made the announcement Monday morning in Alexandria, joined by officials including U.S. Sen.

A new report has warned that the Chinese military is close to achieving technological parity with the U.S., as part of a deliberate and long-term plan for Beijing to develop the world's dominant military force. The report--written by former deputy defense secretary Robert Work and his former special assistant Greg Grant--was published by the Center for a New American Security.

NIST launched this initiative to bring together communities and technology innovators to collaborate on smart city solutions that would be accessible to all because of their reliance on standards-based approaches. The challenge fosters the creation of "action clusters" -- partnerships across government, industry and academia -- to address city and community goals in areas such as energy, transportation, security, public health and others.
