On Saturday, July 29 an exhausted and adrenaline-fueled team from Hyperloop One celebrated another significant milestone, completing the second phase of testing our high-speed Hyperloop pod inside our DevLoop tube north of Las Vegas. By the last run, after almost a week of trials, we had logged more time working with full-scale Hyperloop technology than anyone on the planet. Farther and faster was our mantra for this phase, and our XP-1 test pod went 4.5 times farther and three times faster than our initial runs in May. The XP-1 went as fast as 310 km per hour (190 mph) and

Researchers have achieved a leap forward in graphene production, from a technique that synthesizes a few square centimeters of single-crystal graphene in a couple of hours, to an optimized method that allows the creation of an almost-perfect (over 99.9 percent aligned) 5 × 50 cm2 single-crystal graphene in just 20 minutes. The low production costs, comparable to commercially available lower quality polycrystalline graphene films, could expand its usability. The method is expected to stimulate further fundamental work on graphene and related materials, including large scale folding of graphene sheets, similar to paper, creating origami-like or kirigami-like shapes, which could be

Boeing modernized its 1980s-era Avenger air defense system to answer the Army’s call to fill its Short-range Air Defense gap within the maneuver force. The Avenger first came off the production line at Boeing in 1987 and is known for defending the National Capitol Region. The old systems used Stinger missiles, which are passive infrared munitions. Boeing has fielded 1,100 systems to the U.S. and other nations. There are only four Avenger batteries in the active component – the rest resident in the reserve forces. The Army is expecting to fight in the future in highly contested and congested environments

India, another academic powerhouse, had 2.6 million new STEM graduates last year while the U.S. had 568,000. Chinese STEM graduates outnumber US STEM grads 8.2 to 1. The gap is going to become even wider. Even modest predictions see the number of 25 to 34-year-old graduates in China rising by a further 300% by 2030, compared with an increase of around 30% expected in Europe and the United States.
