| Methods from weather forecasting can be adapted to assess risk of COVID-19 exposure Posted: 23 Jun 2022 01:43 PM PDT Engineers can adapt weather forecasting models to give individuals a personalized assessment of their risk of exposure to COVID-19 or other diseases. |
| Self-assembled, interlocked threads: Spinning yarn with no machine needed Posted: 23 Jun 2022 11:05 AM PDT Researchers unexpectedly discovered that the ability for spirals to form in nature also happens in some non-biological systems that convert chemical energy into mechanical action -- allowing two-dimensional polymer sheets to rise and rotate in spiral helices without the application of external power. This self-assembly into coherent three-dimensional structures represents the group's latest contribution in the field of soft robotics and chemo-mechanical systems. |
| Ultra-thin film creates vivid 3D images with large field of view Posted: 23 Jun 2022 11:05 AM PDT Researchers have developed a new ultra-thin film that can create detailed 3D images viewable under normal illumination without any special reading devices. The images appear to float on top of the film and can be clearly viewed from all angles. The new imaging film uses a technology known as light-field imaging, which captures the direction and intensity of all rays of light within a scene to create a 3D image. With additional development, the new glass-free approach could be used as a visual security feature or incorporated into virtual or augmented reality devices. |
| Personal health trackers may include smart face mask, other wearables Posted: 23 Jun 2022 09:26 AM PDT New research demonstrates different ways to improve wearable bioelectronic devices and materials to provide better real-time monitoring of a person's health, including vital signs. |
| Are babies the key to the next generation of artificial intelligence? Posted: 23 Jun 2022 08:09 AM PDT Babies can help unlock the next generation of artificial intelligence (AI), according to neuroscientists who have just published new guiding principles for improving AI. The research examines the neuroscience and psychology of infant learning and distills three principles to guide the next generation of AI, which will help overcome the most pressing limitations of machine learning. |
| Modeling a devastating childhood disease on a chip Posted: 23 Jun 2022 08:09 AM PDT Millions of children globally suffer from environmental enteric dysfunction (EED), a chronic inflammatory disease of the intestine that causes malnutrition and stunts their growth. A new Organ Chip models this devastating disease in living human tissue for the first time in vitro. This EED Chip allowed researchers to tease out the complex interplay of genetics and nutrition underpinning the disease, and offers clues for the development of future treatments. |
| Can robotics help us achieve sustainable development? Posted: 22 Jun 2022 08:31 AM PDT Scientists have assessed how robotics and autonomous systems might facilitate or impede the delivery of the UN Sustainable Development Goals (SDGs). Their findings identify key opportunities and key threats that need to be considered while developing, deploying and governing robotics and autonomous systems. |
| Tiny fish-shaped robot 'swims' around picking up microplastics Posted: 22 Jun 2022 07:13 AM PDT Microplastics are found nearly everywhere on Earth and can be harmful to animals if they're ingested. But it's hard to remove such tiny particles from the environment, especially once they settle into nooks and crannies at the bottom of waterways. Now, researchers have created a light-activated fish robot that 'swims' around quickly, picking up and removing microplastics from the environment. |
