| Drones show promise in speeding up communication with underwater robots for ocean surveys Posted: 29 Oct 2021 08:40 AM PDT Researchers have investigated the performance capability of unmanned aerial vehicles (UAVs) as a communication platform with autonomous underwater vehicles (AUVs) for ocean and seafloor monitoring research. Studies suggest that UAVs exhibit suitable communication performance for underwater measurement up to approximately 1 km from the shore, owing to their operation speed, robust hovering control, and stability against sea-surface sway. Further studies are necessary for more complicated applications. |
| Researchers set ‘ultrabroadband’ record with entangled photons Posted: 29 Oct 2021 08:40 AM PDT Researchers take advantage of quantum entanglement to generate an incredibly large bandwidth using a thin-film nanophotonic device that could lead to advances in metrology, sensing and quantum networks for information processing and communications. |
| Blasting the 'zombie' out of water-saving tech Posted: 29 Oct 2021 08:39 AM PDT Scientists suggest that reliance on modern irrigation technologies as a water-use efficiency strategy is a 'zombie idea' -- one that persists no matter how much evidence is thrown against it. Technology adoption as a water-saving method for improving irrigation efficiency is ineffective, and can actually worsen water scarcity, according to researchers. |
| Computational discovery of complex alloys could speed the way to green aviation Posted: 29 Oct 2021 07:31 AM PDT Experts have identified the way to tune the strength and ductility of a class of materials called high-entropy alloys. The discovery may help power-generation and aviation industry develop more efficient engines. |
| Posted: 29 Oct 2021 07:30 AM PDT A recent project has revealed new bone formation in critical bone defects of an animal model with an exposure to a pencil-type non-thermal atmospheric-pressure plasma at surgery. |
| A novel way to generate visible light Posted: 29 Oct 2021 04:49 AM PDT An international research team demonstrates how to generate extremely short pulses of visible light using an industrial-grade laser system. |
