5G should be 10 to 20 times faster than today’s cell-phone networks. 5G will operate in a high-frequency portion of the radio spectrum, known as millimeter wave. It has a lot of available bandwidth and should make it possible for wireless devices to process data with minimal delays. But since its wavelengths are much shorter, …
Israel’s Ministry of Defense (IMOD) plans to continue the acquisition of Trophy active protection systems (APS), to equip every new Merkava 4 tank and Namer Heavy Armored Personnel Carrier (APC) with active protection, providing significant additional protection for every tank and APC. Each Trophy system integrates an early warning and battle management radar covering 360 …
When light strikes electrons in atoms, their state can change unimaginably quickly. Laser physicists in Munich have measured such a phenomenon – namely that of photoionization, in which an electron exits a helium atom after excitation by light – for the first time with zeptosecond precision. A zeptosecond is a trillionth of a billionth of …
Nearly a decade of research showing that Rapamycin makes mice live up to 60% longer, scientists are trying it out as an anti-aging drug in dogs and humans. Researchers at the University of Washington’s Dog Aging Project gave rapamycin to 16 dogs and imaged their hearts. “It started to function better. It started to look …
The Pentagon’s emerging “Arsenal Plane” or “flying bomb truck” is likely to be a modified, high-tech adaptation of the iconic B-52 bomber designed to fire air-to-air weapons, release swarms of mini-drones and provide additional fire-power to 5th generation stealth fighters such as the F-35 and F-22, Pentagon officials and analysts said. It is also possible …
Memory performance typically declines with age, as does cortical structural integrity, yet some older adults maintain youthful memory. We tested the hypothesis that superagers (older individuals with youthful memory performance) would exhibit preserved neuroanatomy in key brain networks subserving memory. We found that superagers not only perform similarly to young adults on memory testing, they …
Plans to construct six Westinghouse AP1000s in India have been bolstered by a joint statement issued after a bilateral strategic dialogue yesterday between the USA and India. The two sides also pledged to work towards India’s entry into the Nuclear Suppliers Group (NSG). The AP1000 is a pressurized water reactor with two cooling loops, planned …
Russia’s first fifth-generation fighter project, the “MiG 1.44,” produced a single prototype before cancellation. The advent of the F-22 Raptor, and the expectation that the United States would follow up with large numbers of F-35s, made the development of a fifth-generation fighter imperative for Russia. Perception of this need resulted in the award of a …
A simple filtration process helped Rice University researchers create flexible, wafer-scale films of highly aligned and closely packed carbon nanotubes. Scientists at Rice, with support from Los Alamos National Laboratory, have made inch-wide films of densely packed, chirality-enriched single-walled carbon nanotubes In the right solution of nanotubes and under the right conditions, the tubes assemble …
Robotic in orbit assembly and laser propulsion could enable vast increases in space capability while not significantly changing the world civilization energy budget. Robotic and additive manufacturing could enable massive frames and massive solar power arrays Tethers Unlimited is currently developing a revolutionary suite of technologies called “SpiderFab” to enable on-orbit fabrication of large spacecraft …
Faraday Future showed off an electric supercar concept car at CES 2016. Faraday Future has been operating for 18 months now in stealth mode in Los Angeles, the team has quietly grown to 750, many of them poached from auto and tech giants such as Tesla, BMW and Apple. The company is largely funded by …
