| Physicists embark on a hunt for a long-sought quantum glow Posted: 26 Apr 2022 01:26 PM PDT Researchers say they've found a way to significantly increase the probability of observing the Unruh effect, a 'quantum glow' phenomenon that was first proposed in the 1970s. |
| Posted: 26 Apr 2022 01:25 PM PDT Novel system could lead to catalysts based on cheaper, more abundant nickel rather than more expensive precious metals. |
| Measuring the 'wettability' of graphene and other 2D materials Posted: 26 Apr 2022 12:36 PM PDT Measuring the 'wettability' of graphene and other 2D materials. Microscopic understanding of wettability can be achieved at the molecular level using 'vibrational sum-frequency generation spectroscopy' (VSFG). |
| Researchers develop a paper-thin loudspeaker Posted: 26 Apr 2022 12:36 PM PDT Researchers created an ultrathin loudspeaker that can turn any rigid surface into a high-quality, active audio source. The fabrication process can enable the thin-film devices to be produced at scale. |
| Best version of exosuit to take strain off the back Posted: 26 Apr 2022 12:36 PM PDT A research team studies exosuits, a wearable mobile machine that allows for limb movement with increased strength and endurance. |
| Researchers unveil a highly efficient means to reverse magnetization with spin currents Posted: 26 Apr 2022 07:17 AM PDT Researchers have established a low-cost method of magnetization reversal on perpendicularly magnetized ferromagnets. Not needing an external magnetic field, the method brings reverse magnetization closer to commercial viability. |
| Scientists use recycled glass waste as sand replacement in 3D printing Posted: 26 Apr 2022 07:17 AM PDT Researchers have developed the capability to use recycled glass in 3D printing, opening doors to a more environmentally sustainable way of building and construction. |
| Learning chemical networks give life a chiral twist Posted: 26 Apr 2022 07:17 AM PDT A study shows that the preference of biological molecules for left or right-handedness -- a hallmark of living matter -- could emerge spontaneously as prebiotic chemical networks adapt to optimize energy harvesting. The proposed mechanism of symmetry breaking is general and can apply to other transitions in living matter that lead to increased complexity. |
| Microrobot collectives display versatile movement patterns Posted: 26 Apr 2022 07:16 AM PDT Collective behavior and swarm patterns are found everywhere in nature. Robots can also be programmed to act in swarms. Researchers have developed collectives of microrobots, which they can move in every formation they wish. |
| New graphite based rapid sensor chip for real-time theophylline monitoring Posted: 26 Apr 2022 07:16 AM PDT Although theophylline (THO) is effective in treating respiratory problems and inflammation, the drug can be toxic if taken above certain limits. This demands accurate and rapid sensing devices that can closely monitor THO levels in patients. Therefore, scientists have now designed a paper-based THO sensor with a response time of 3 seconds. This new sensor is highly selective and sensitive. It has also been successfully tested using whole bovine blood. |
| Terahertz imaging reveals hidden inscription on early modern funerary cross Posted: 25 Apr 2022 02:21 PM PDT Using terahertz imaging and signal processing techniques to look beneath the corroded surface of a 16th-century lead funerary cross, researchers have revealed an inscription of the Lord's Prayer. |
| An easier way to teach robots new skills Posted: 25 Apr 2022 12:43 PM PDT Researchers have developed a technique that enables a robot to learn a new pick-and-place task with only a handful of human demonstrations. This could allow a human to reprogram a robot to grasp never-before-seen objects, presented in random poses, in about 15 minutes. |
| New research harnesses the power of movement Posted: 25 Apr 2022 10:59 AM PDT Harvesting energy from the day-to-day movements of the human body and turning it into useful electrical energy, is the focus of a new piece of research. Academics have developed a unique design for sensors capable of using human movements -- such as bending, twisting and stretching -- to power wearable technology devices including smart watches and fitness trackers. |
| Cheaper hydrogen fuel cell could mean better green energy options Posted: 25 Apr 2022 09:11 AM PDT Researchers have developed a hydrogen fuel cell that uses iron instead of rare and costly platinum, enabling greater use of the technology. |
| A new era of mitochondrial genome editing has begun Posted: 25 Apr 2022 09:11 AM PDT A new era of mitochondrial genome editing has begun. Scientists successfully achieve A to G base conversion, the final missing piece of the puzzle in gene-editing technology. |
