Attosecond Resolution

Researchers demonstrate an on-chip, optoelectronic device capable of sampling arbitrary, low-energy, near-infrared waveforms under ambient conditions with sub-optical-cycle resolution. The detector uses field-driven photoemission from resonant nanoantennas to create attosecond electron bursts that probe the electric field of weak optical waveforms. Using these devices, they sampled the electric fields of ~5 fJ (6.4 MV m−1), few-cycle, near-infrared waveforms …

Lithium niobate could enable a photonics revolution the way silicon enabled computer revolution

The birthplace of the photonics revolution may well be named after lithium niobate. While, Lithium Niobate Valley doesn’t have the same ring as Silicon Valley, this material could be for optics what silicon was for electronics. Lithium niobate is already one of the most widely used optical materials, well-known for its electro-optic properties, meaning it …

Multi-colored photons from off the shelf components can make vastly more powerful quantum systems

INRS researchers have achieved a breakthrough in a light-weight photonic system created using on-chip devices and off-the-shelf telecommunications components. They demonstrated that photons can become an accessible and powerful quantum resource when generated in the form of color-entangled quDits. The system uses a small and cost-effective photonic chip fabricated through processes similar to those used …

China’s New 25 ton capacity Long March 5 rocket is on the launch pad and ready for November launch

China’s largest carrier rocket, the Long March-5, will make its first trip into space in early November this year. The rocket, which arrived at the Wenchang launch center in south China’s Hainan Province in September, was transported to the launch area on Friday morning, after finishing final assembly and tests, said the State Administration of …

Precision farming reducing farm water usage by five times and super greenhouses cut growing times nearly in half

With a new irrigation system that waters a little-but-often an almond farmer uses 20% less water than he used to. Growing a single almond used to consume around a gallon of water. This is merely an American gallon of 3.8 liters. So now it is about 0.95 liters. Moisture sensors planted throughout almond nut groves …

NASA and Lockheed building a Quieter Supersonic Passenger Jet

NASA announced that they’d awarded defense giant Lockheed Martin a $20 million contract for 17 months of preliminary development on a quiet supersonic plane. The return of supersonic passenger air travel is one step closer to reality with NASA’s award of a contract for the preliminary design of a “low boom” flight demonstration aircraft. This …

Centimeter-long origami robot

A team of MIT researchers have developed a printable origami robot that folds itself up from a flat sheet of plastic when heated and measures about a centimeter from front to back. The robot’s design was motivated by a hypothetical application in which tiny sheets of material would be injected into the human body, navigate …

Space Coaches – Reusable Refuelable Interplanetary Spacecraft made mostly of water at one hundredth the cost of conventional chemical rockets

A website, spacecoach.org, expands on a 2010 paper which describes a design for a reusable interplanetary spacecraft made mostly out of water or pykrete (ice frozen with fiber material). The proposed design “burns” water in microwave electrothermal engines, a type of electric propulsion system that has been tested with water as propellant, and proven to …

DARPA wants to convert C130 and other planes into Drone carriers

DARPA wants to enable existing large aircraft to carry, launch and recover multiple unmanned air systems for a variety of missions. Military air operations typically rely on large, manned, robust aircraft, but such missions put these expensive assets—and their pilots—at risk. While small unmanned aircraft systems (UAS) can reduce or eliminate such risks, they lack …
