| Engineers get under the skin of ionic skin Posted: 28 Apr 2022 11:28 AM PDT In the quest to build smart skin that mimics the sensing capabilities of natural skin, ionic skins have shown significant advantages. They're made of flexible, biocompatible hydrogels that use ions to carry an electrical charge. These hydrogels can generate voltages when touched, but scientists did not clearly understand how -- until a team of researchers devised a unique experiment. |
| Posted: 28 Apr 2022 07:40 AM PDT Scientists describe a new technique that promises to revolutionize the imaging of proteins and other vital biomolecules, allowing these tiny entities to be visualized with unprecedented clarity and by simpler means than existing methods. |
| From blurry to bright: AI tech helps researchers peer into the brains of mice Posted: 28 Apr 2022 07:39 AM PDT Biomedical engineers have developed an artificial intelligence (AI) training strategy to capture images of mouse brain cells in action. The researchers say the AI system, in concert with specialized ultra-small microscopes, make it possible to find precisely where and when cells are activated during movement, learning and memory. |
| Ionic liquid-based reservoir computing: The key to efficient and flexible edge computing Posted: 28 Apr 2022 05:58 AM PDT Researchers have designed a tunable physical reservoir device based on the dielectric relaxation at an electrode-ionic liquid interface. Physical reservoir computing (PRC), which relies on the transient response of physical systems, is an attractive machine learning framework that can perform high-speed processing of time-series signals at low power. |
| In Einstein's footsteps and beyond Posted: 27 Apr 2022 12:41 PM PDT Physicists are re-examining the foundations of quantum physics from the perspective of momentum and exploring what happens when the momentum of light is reduced to zero. |
| New device: Tallest height of any known jumper, engineered or biological Posted: 27 Apr 2022 12:41 PM PDT A mechanical jumper is capable of achieving the tallest height -- roughly 100 feet (30 meters) -- of any jumper to date, engineered or biological. The feat represents a fresh approach to the design of jumping devices and advances the understanding of jumping as a form of locomotion. |
| Plug-and-play organ-on-a-chip can be customized to the patient Posted: 27 Apr 2022 08:57 AM PDT Researchers have developed a model of human physiology in the form of a multi-organ chip consisting of engineered human heart, bone, liver, and skin that are linked by vascular flow with circulating immune cells, to allow recapitulation of interdependent organ functions. The researchers have essentially created a plug-and-play multi-organ chip, which is the size of a microscope slide, that can be customized to the patient. |
| COVID-19 lockdown measures affect air pollution from cities differently Posted: 26 Apr 2022 12:37 PM PDT Seizing on a natural experiment created by restricted travel, researchers combine a network model with air pollution data before and during outbreaks. |
