Stratospheric sulfate aerosol geoengineering may mitigate effects of climate change. Sulfate could be mixed into jet fuel so that contrails would spread the sulfate into the stratosphere. We would mimick a volcano. If we put 5 billion tons of sulfates a year into the atmosphere 20 kilometers high, and do that for 50 years. These …
The Pentagon on Tuesday awarded the most fiercely-fought weapons contest in more than a decade to Northrop Grumman Corp., a $21.4 billion initial deal to build new long-range bombers for the U.S. Air Force. Northrop Grumman was selected over a Boeing Co. and Lockheed Martin Corp. team to build the first 21 jets to replace …
Back to the Future Part II.” The film got some things right about 2015, including in-home videoconferencing and devices that recognize people by their voices and fingerprints. But it also predicted trunk-sized fusion reactors, hoverboards and flying cars—game-changing technologies that are not. NBF – There are prototype flying cars (roadable planes) which do exist but …
DARPA wants to create the military communication system of tomrrow with the Dynamic Network Adaptation for Mission Optimization (DyNAMO) program. DyNAMO seeks novel technologies that would enable independently designed networks to share information and adapt to sporadic jamming and mission-critical dynamic network bursts in contested RF environments. The program seeks technology that can interconnect existing …
mCube is a fabless semiconductor company founded in 2009 and based in San Jose, California. mCube is the provider of microelectromechanical systems (MEMS) motion sensors for the Internet of Moving Things. From smartphones and tablets to smart clothing and wearables, the Internet of Moving Things (IoMT) is where the movement and context of everyday objects …
A new experimental revelation about black phosphorus nanoribbons should facilitate the future application of this highly promising material to electronic, optoelectronic and thermoelectric devices. A team of researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) has experimentally confirmed strong in-plane anisotropy in thermal conductivity, up to a factor of …
An asthma drug has rejuvenated rat brains, making old rats perform as well as young rats in tests of memory and cognition. The drug also encouraged the birth of new brain cells. As we get older, most of us will experience some kind of brain degeneration. Typically, we lose the ability to make new neurons. …
An important step towards next-generation ultra-compact photonic and optoelectronic devices has been taken with the realization of a two-dimensional excitonic laser. Scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) embedded a monolayer of tungsten disulfide into a special microdisk resonator to achieve bright excitonic lasing at visible light wavelengths. …
Samsung has unveiled a new line of battery prototype which provide as much as 50% more battery life to wearables by forming the watch band. The batteries are bendable. Samsung SDI unveiled the company’s Stripe and Band batteries at the recent InterBattery 2015 event at COEX, Seoul, South Korea. The Stripe battery is designed to …
On Oct. 28, 2015, NASA’s Cassini spacecraft will take the deepest dive ever through the plume of Saturn’s moon Enceladus. Scientists hope this close flyby will shed light on what’s happening beneath the moon’s icy surface. With a global ocean and likely hydrothermal activity, could Enceladus have the ingredients needed to support simple forms of …
An ultrapure material taken to pressures greater than that in the depths of the ocean and chilled to temperatures colder than outer space has revealed an unexpected phase transition that crosses two different phase categories. A Purdue University-led team of researchers observed electrons transition from a topologically ordered phase to a broken symmetry phase. “To …
