| Music-making and the flow of aerosols Posted: 14 Jul 2022 01:58 PM PDT If simply breathing can spread the SARS-CoV-2 virus to others nearby, what about blowing into a tuba? Researchers used fluid mechanics to study the movement of aerosols generated by professional musicians. |
| Posted: 14 Jul 2022 11:51 AM PDT As our devices become smaller, faster, more energy efficient, and capable of holding larger amounts of data, spintronics may continue that trajectory. Whereas electronics is based on the flow of electrons, spintronics is based on the spin of electrons. |
| Posted: 14 Jul 2022 11:51 AM PDT Theoretical physicists put Google's artificial intelligence AlphaFold to the test and find the most complex protein knots so far. |
| 'Life-like' lasers can self-organize, adapt their structure, and cooperate Posted: 14 Jul 2022 11:50 AM PDT By mimicking features of living systems, self-organizing lasers could lead to new materials for sensing, computing, light sources and displays. |
| Eco-friendly sound absorbers from seaweed Posted: 14 Jul 2022 11:50 AM PDT From airplanes to apartments, most spaces are now designed with sound-absorbing materials that help dampen the droning, echoing and murmuring sounds of everyday life. But most of the acoustic materials that can cancel out human voices, traffic and music are made from plastic foams that aren't easily recycled or degraded. Now, researchers have created a biodegradable seaweed-derived film that effectively absorbs sounds in this range. |
| Nanotube-embedded coating detects threats from wear and tear in large structures Posted: 14 Jul 2022 11:50 AM PDT Carbon nanotubes' natural fluorescence enables a method to detect high strain concentrations that can lead to damage threatening the integrity of critical infrastructure like aircraft, buildings, pipelines, bridges and ships. |
| A new peptide system for the targeted transport of molecules into living mammalian cells Posted: 14 Jul 2022 11:43 AM PDT Scientists have developed a novel peptide suitable for the targeted transport of molecules -- for example, active substances and dyes -- into the cells of mammals. |
| Changes in protein structure and assembly with fluoride nanoparticles and coexisting ions Posted: 14 Jul 2022 07:30 AM PDT Scientists demonstrate the influence of nanoparticles and surrounding ions on the formation of beta-sheet structure in amyloid beta proteins. |
| Photovoltaics: Fully scalable all-perovskite tandem solar modules Posted: 14 Jul 2022 07:30 AM PDT Optimized light paths, high-throughput laser scribing and the use of established coating processes paves the way to commercial viability. |
| Waves in the maze of no return: Anti-reflective structure for perfect transmission Posted: 14 Jul 2022 07:30 AM PDT Researchers have developed a surprising method to eliminate wave reflections. The method allows the calculation of a tailor-made anti-reflective structure. It can be used, for example, to design an additional layer to a wall that is only partially permeable to a wireless signal so that the entire signal can be channeled through the wall without reflections. |
| Action of drug compounds in tissue revealed by new technique Posted: 14 Jul 2022 06:51 AM PDT A new technique that can analyze how drug molecules bind to proteins in tissue samples could offer an improved route to drug discovery and development. |
| Researchers use quantum-inspired approach to increase lidar resolution Posted: 13 Jul 2022 12:42 PM PDT Researchers have shown that a quantum-inspired technique can be used to perform lidar imaging with a much higher depth resolution than is possible with conventional approaches. Lidar, which uses laser pulses to acquire 3D information about a scene or object, is usually best suited for imaging large objects such as topographical features or built structures due to its limited depth resolution. |
| Researchers develop computer model to predict whether a pesticide will harm bees Posted: 13 Jul 2022 12:28 PM PDT Researchers have harnessed the power of artificial intelligence to help protect bees from pesticides. |
| Microparticles could be used to deliver 'self-boosting' vaccines Posted: 13 Jul 2022 11:39 AM PDT Engineers have developed microparticles made of a biocompatible polymer that can deliver a payload at different time points and could be used to create 'self-boosting' vaccines. |
| A robot learns to imagine itself Posted: 13 Jul 2022 11:39 AM PDT Researchers have created a robot that is able to learn a model of its entire body from scratch, without any human assistance. In a new study, the researchers demonstrate how their robot created a kinematic model of itself, and then used its self-model to plan motion, reach goals, and avoid obstacles in a variety of situations. It even automatically recognized and then compensated for damage to its body. |
| Underwater glove puts octopus' abilities on the hand of humans Posted: 13 Jul 2022 11:39 AM PDT A team of researchers has developed an octopus-inspired glove capable of securely gripping objects underwater. This is significant because humans aren't naturally equipped to thrive underwater. There are critical times when this becomes a liability. Rescue divers, underwater archeologists, bridge engineers, and salvage crews all use their hands to extract people and objects from water, and some of those removals suffer damage if subjected to an iron grip. |
| Atomically-smooth gold crystals help to compress light for nanophotonic applications Posted: 13 Jul 2022 11:39 AM PDT Highly compressed mid-infrared optical waves in a thin dielectric crystal on monocrystalline gold substrate investigated for the first time using a high-resolution scattering-type scanning near-field optical microscope. |
| Off-road motorcycles put four times more kids in hospital than quad-bikes Posted: 13 Jul 2022 08:46 AM PDT Safety of off-road motorcycles needs more attention as study shows two-wheelers account for more hospitalization of children in NSW, Australia, than quad-bikes. |
