| Creating order by mechanical deformation in dense active matter Posted: 27 Sep 2021 02:29 PM PDT Living or biological systems cannot be easily understood using the standard laws of physics, such as thermodynamics, as scientists would for gases, liquids or solids. Living systems are active, demonstrating fascinating properties such as adapting to their environment or repairing themselves. Exploring the questions posed by living systems using computer simulations, researchers have now discovered a novel type of ordering effect generated and sustained by a simple mechanical deformation, specifically steady shear. |
| Ultrathin quantum dot LED that can be folded freely as paper Posted: 27 Sep 2021 08:05 AM PDT Scientists have unveiled an ultrathin quantum dot LED that can be folded as freely as paper. The new device can be folded into complex 3D structures such as butterflies, airplanes, and pyramids. |
| Contact-tracing apps could improve vaccination strategies Posted: 22 Sep 2021 11:32 AM PDT Mathematical modeling of disease spread suggests that herd immunity could be achieved with fewer vaccine doses by using Bluetooth-based contact-tracing apps to identify people who have more exposure to others -- and targeting them for vaccination. |
