[ad_1] Shantanu Chakrabartty’s laboratory has worked to create sensors that can operate with the least amount of energy. His lab has been so successful in building smaller, more efficient sensors, that they have encountered an obstacle in the form of a fundamental law of physics. Sometimes, however, when you encounter …

[ad_1] Scientists reported a new optical imaging technology, which uses a glass side coated with gold nanodiscs that allows them to monitor changes in light transmission and determine the characteristics of nanoparticles as small as 25 nanometers in diameter. Current cutting-edge techniques have clear limitations when it comes to visualizing …

[ad_1] It’s no exaggeration to say that extendable sensors could change the way soft robots work and feel. In fact, they will be able to try quite a lot. Cornell researchers have created a fiber-optic sensor that combines low-cost LEDs and dyes, resulting in a stretchable “skin” that detects deformations …

[ad_1] LOS ALAMOS, NM, November 12, 2020: Two new studies of the brightest lightning events on Earth, called “superbolt”, have found that they are distinct from normal lightning and can be over 1,000 times brighter. The new findings could help scientists better understand these mysterious strikes and inform safety efforts, …

[ad_1] The white-breasted nuthatch has good low-light vision and has anticipated nesting times in response to light exposure, according to a new study in the journal Nature. Image credit: Dave Keeling Are you looking for a bird’s-eye view of human impact? A new study in the journal Nature provides the …

[ad_1] Newswise – A team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) has invented an artificial olfactory system that mimics the nose of mammals to accurately assess the freshness of meat. The “electronic nose” (e-nose) comprises a “barcode” that changes color over time in reaction to the …

[ad_1] A new model shows how the brine on Jupiter’s moon Europa can migrate inside the frozen shell to form pockets of salt water that erupt to the surface when it freezes. The findings, important for the upcoming Europa Clipper mission, could explain cryo-volcanic eruptions through the frozen bodies of …

[ad_1] Metal-organic structures (MOFs) are a class of porous and crystalline materials that are synthesized from inorganic metal ions or clusters attached to organic ligands. Two of these materials are shown, HKUST-1 and MIL-100 (Fe). (Credit: Tania Evans, Georgia Tech) An artificial intelligence technique, machine learning, is helping to accelerate …

[ad_1] The integrated detector combines a silicon photonic chip with a silicon microelectronic chip, delivering an advanced speed in quantum light detection. Bristol researchers have developed a tiny device that paves the way for higher-performance quantum computers and quantum communications, making them significantly faster than the current state of the …
