A new phase in Bose-Einstein condensate of light particles observed
A single "super photon" made up of many thousands of individual light particles: About ten years ago, researchers at the University of Bonn produced such an extreme aggregate state for the first time and presented a completely new light source. The state is called optical Bose-Einstein condensate and has captivated many physicists ever since, because this exotic world of light particles is home
Even without a brain, Penn Engineering's metal-eating robots can search for food
When it comes to powering mobile robots, batteries present a problematic paradox: the more energy they contain, the more they weigh, and thus the more energy the robot needs to move. Energy harvesters, like solar panels, might work for some applications, but they don't deliver power quickly or consistently enough for sustained travel. James Pikul, assistant professor in Penn Engineering's
Rise of the 'robo-plants', as scientists fuse nature with tech
Remote-controlled Venus flytrap "robo-plants" and crops that tell farmers when they are hit by disease could become reality after scientists developed a high-tech system for communicating with vegetation. Researchers in Singapore linked up plants to electrodes capable of monitoring the weak electrical pulses naturally emitted by the greenery. The scientists used the technology to trigger
Thermal power nanogenerator created without solid moving parts
As environmental and energy crises become increasingly more common occurrences around the world, a thermal energy harvester capable of converting abundant thermal energy - such as solar radiation, waste heat, combustion of biomass, or geothermal energy - into mechanical energy appears to be a promising energy strategy to mitigate many crises. The majority of thermal power generation techno
A sun reflector for earth?
Nine of the hottest years in human history have occurred in the last decade. Without a major shift in this climate trajectory, the future of life on Earth is in question. Should humans, whose fossil-fueled society is driving climate change, use technology to put the brakes on global warming? Every month since September 2019 the Climate Intervention Biology Working Group, a team of internat
An Australian 'space command' could be a force for good - or a cause for war
As the Royal Australian Air Force (RAAF) celebrated 100 years with a spectacular and well-attended flyover in Canberra yesterday, many eyes were lifted to the skies. But RAAF's ambitions go even higher, as its motto "through adversity, to the stars" hints. The Chief of Air Force, Air Marshall Mel Hupfeld, announced the intention to create a new "space command". Having a dedicated space com
SBIRS GEO Flight 5: RocketShip delivers Atlas V for Space Force launch
A United Launch Alliance (ULA) Atlas V rocket built to carry a sophisticated U.S. national security satellite into space arrived at Cape Canaveral, FL today after sailing from the factory aboard the R/S RocketShip. The Atlas V booster stage and Centaur upper stage left the ULA manufacturing facility in Decatur, AL, on March 23 aboard our unique custom-built rocket transportation vessel. Th
Scientists achieve single-photon imaging over 200km
A research team led by Professor PAN Jianwei and Professor XU Feihu from University of Science and Technology of China achieved single-photon 3D imaging over 200 km using high-efficiency optical devices and a new noise-suppression technique, which is commented by the reviewer as an almost "heroic" attempt at single photon lidar imaging at very long distances. Lidar imaging technology has e
Less than a nanometer thick, stronger and more versatile than steel
Scientists create stable nanosheets containing boron and hydrogen atoms with potential applications in nanoelectronics and quantum information technology. What's thinner than thin? One answer is two-dimensional materials - exotic materials of science with length and width but only one or two atoms in thickness. They offer the possibility of unprecedented boosts in device performance for el
Early combined tests mimic Ariane 6 liftoff
Ariane 6 early combined tests at Latesys in Fos-sur-Mer, in France, have simulated the moment of liftoff when the umbilicals separate from the launch vehicle.
