| Light-powered soft robots could suck up oil spills Posted: 02 Dec 2021 11:15 AM PST A floating, robotic film could be trained to hoover oil spills at sea or remove contaminants from drinking water. |
| Color-changing magnifying glass gives clear view of infrared light Posted: 02 Dec 2021 11:14 AM PST By trapping light into tiny crevices of gold, researchers have coaxed molecules to convert invisible infrared into visible light, creating new low-cost detectors for sensing. |
| Green information technologies: Superconductivity meets spintronics Posted: 02 Dec 2021 10:24 AM PST Superconducting coupling between two regions separated by a one micron wide ferromagnetic compound has been proved by an international team. This macroscopic quantum effect, known as Josephson effect, generates an electrical current within the ferromagnetic compound made of superconducting Cooper-pairs. Magnetic imaging of the ferromagnetic region at BESSY II has contributed to demonstrate that the spin of the electrons forming the Cooper pairs are equal. These results pave the way for low-power consumption superconducting spintronic-applications where spin-polarized currents can be protected by quantum coherence. |
| Two-photon microscope provides unprecedented brain-imaging ability Posted: 02 Dec 2021 09:30 AM PST Advancing our understanding of the human brain will require new insights into how neural circuitry works in mammals, including laboratory mice. These investigations require monitoring brain activity with a microscope that provides resolution high enough to see individual neurons and their neighbors. |
| Growing carbon footprint for plastics Posted: 02 Dec 2021 08:35 AM PST After analyzing the global plastics supply chain, researchers found that the impact of plastics on the climate and health is greater than thought due to the increased use of coal for process heat, electricity and as a raw material in production. |
| A pair of gold flakes creates a self-assembled resonator Posted: 02 Dec 2021 06:30 AM PST For exploring materials right down to the nano-level, researchers often need to construct a complex structure to house the materials -- a time-consuming and complicated process. But imagine if there was a way the structure could simply build itself? |
| Improving perceptions of emerging technologies can help ease strain on health-care systems Posted: 02 Dec 2021 06:29 AM PST More attention must be paid to improving perceptions of emerging technologies like AI-powered symptom checkers, which could ease the strain on health-care systems, according to a recent study. |
| Which role models are best for STEM? Researchers offer recommendations in new analysis Posted: 01 Dec 2021 05:39 PM PST An analysis of the effect role models have on students' motivation in studying STEM subjects points to new ways to deploy these leaders in order to encourage learning across different populations. |
| New computational approach predicts chemical reactions at high temperatures Posted: 01 Dec 2021 05:51 AM PST Engineers invent 'green' method that combines quantum mechanics with machine learning to accurately predict oxide reactions at high temperatures when no experimental data is available; could be used to design clean carbon-neutral processes for steel production and metal recycling. |
| Shrinking qubits for quantum computing with atom-thin materials Posted: 30 Nov 2021 02:39 PM PST Current approaches to create superconducting qubits for quantum computers yield chips that are substantially larger than those found in classical computers. To shrink things down, researchers have taken advantage of atomically thin, 2D materials to construct the necessary capacitors for superconducting qubits. Their two-qubit chip is 1,000x smaller than those made with conventional fabrication techniques. |
| Researchers develop rapid, highly accurate test to detect viruses Posted: 29 Nov 2021 09:27 AM PST Researchers have developed a device that detects viruses in the body as fast as and more accurately than current, commonly used rapid detection tests. The optical sensor uses nanotechnology to accurately identify viruses in seconds from blood samples. Researchers say the device can tell with 95 percent accuracy if someone has a virus. |
| Breakthrough in surface-based groundwater measurement Posted: 24 Nov 2021 12:40 PM PST A team of researchers has developed an effective technology to carry out very accurate, non-invasive groundwater measurements in previously inaccessible areas. Using the new technology, NMR measurements (nuclear magnetic resonance) are now a cheap, fast and, above all, very accurate tool for mapping and characterizing groundwater systems. |
