China is flying the first airframe in the inaugural production batch of J-20 stealth fighters. The first J-20 squadron expected to be fully delivered by year’s end, the China Flight Testing Evaluation regiment will being developing operating procedures, tactics and technical proficiency to bring the J-20 to combat readiness. At this pace, it is expected …
Prof. Ulrich Wiesner, material science and engineering, created the first ever self-assembled, three-dimensional superconductor with a research group of graduate students and professors of different disciplines. This is the first time a superconductor has self-assembled into a porous, three-dimensional gyroidal structure. After years of collaboration with co-author Prof. Sol Gruner, physics, Wiesner developed the idea …
Despite the scheduled closure of more than 2,000 megawatts (MW) of nuclear generating capacity by 2019, scheduled additions of more than 5,000 MW of capacity between 2016 and 2020 could result in a net increase in total U.S. nuclear capacity. Entergy Corp. announced in October its intention to close by mid-2019 the 685 MW Pilgrim …

Part of a gene variant present in some wild African chimps is nearly identical to a section of an analogous gene version found in HIV-infected humans who are uncharacteristically slow to progress to full-blown AIDS. A gene variant in chimpanzees in a Tanzanian wildlife preserve probably protects them from rapidly succumbing to the primate equivalent …
The GE9X was selected to power the new Boeing 777X. The GE9X will be the most fuel-efficient engine GE has ever produced on a per-pounds-of-thrust basis, designed to achieve a 10% improved aircraft fuel burn versus the GE90-115B-powered 777-300ER and a 5% improved specific fuel consumption versus any twin-aisle engine at service entry. In addition, …
NASA examined revolutionary aerospace systems concepts for human space exploration of the solar system beyond Mars orbit and identified critical technology requirements for the realization of these systems concepts. Due to its distance from Jupiter’s powerful radiation belt, Callisto is subject to only 0.01 rem a day. When NASA carried out a study called HOPE …
Spacex is expected to begin a series of review boards with the U.S. government’s chief engineer the week of Oct. 27 as it enters the “final phase” of its quest to earn the Air Force certification necessary to launch national security missions, a service spokeswoman said. Spacex has provided data from three successful launches for …
UAVs are “a mainstay,” said Ryan Hartman, senior vice presidents of Programs at Insitu, owned by Boeing. Over the next 25 years, he said, “Technology will have evolved to the point where we’ll be operating unmanned systems in the national airspace safely and responsibly.” Insitu demonstrated the launch and recovery of a 45-pound ScanEagle UAV …
The Department of Defense needs materials for armor windows that provide essential protection for both personnel and equipment while still having a high degree of transparency. To meet that need, scientists at the U.S. Naval Research Laboratory (NRL) have developed a method to fabricate nanocrystalline spinel that is 50% harder than the current spinel armor …
Uranium production in Kazakhstan amounted to 22,500 tons in 2013, which corresponds to the planned targets. Kazakhstan produced 20,900 tons of uranium in 2012. The exports on contracts in Kazakhstan (excluding Stepnogorsk Mining-Chemical Complex) amounted to 23,400 tons of uranium concentrate. Kazakhstan has maintained leadership in the global uranium mining industry, providing more than 38 …
