| Metasurfaces control polarized light at will Posted: 13 Aug 2021 03:07 PM PDT Researchers have uncovered hidden potential in metasurfaces and demonstrated optical devices that manipulate light's polarization state with an unprecedented degree of control. The research demonstrates a new way to control polarized light with metasurfaces. This new approach -- in which the researchers can engineer a holographic image with a polarization-tunable response across the image itself -- could lead to applications in diverse fields including imaging, microscopes, displays, and even astronomy. |
| Polymer enables tougher recyclable thermoplastics Posted: 13 Aug 2021 12:20 PM PDT Researchers took a middling monomer and, by using a special catalyst, they created a tougher polymer that can form long chains. The polymer can then be easily depolymerized back to the monomer state with an acid catalyst, resulting in a chemically recyclable thermoplastic that competes with the most popular plastics, polyethylene and polypropylene. |
| Why boiling droplets can race across hot oily surfaces Posted: 13 Aug 2021 12:19 PM PDT Researchers have discovered why boiling droplets can race across hot oily surfaces. The commonplace phenomenon, now quantified for the first time, could be harnessed for many useful applications. |
| Faster path planning for rubble-roving robots Posted: 13 Aug 2021 12:19 PM PDT Robots that need to use their arms to make their way across treacherous terrain just got a speed upgrade with a new path planning approach. The improved algorithm path planning algorithm found successful paths three times as often as standard algorithms, while needing much less processing time. |
| A holistic approach to materials for the next generation of electrical insulation Posted: 13 Aug 2021 07:55 AM PDT Researchers are analyzing new materials for electrical insulation, or packaging, that can remove heat more effectively compared to today's insulation, amid a need to redesign our electrical infrastructure for the next 100 years and beyond to match advanced technology. |
| New algorithm can help improve cellular materials design Posted: 13 Aug 2021 07:03 AM PDT New research has revealed that a simple but robust algorithm can help engineers to improve the design of cellular materials that are used in a variety of diverse applications ranging from defense, bio-medical to smart structures and the aerospace sector. |
| Progress in algorithms makes small, noisy quantum computers viable Posted: 13 Aug 2021 07:03 AM PDT Instead of waiting for fully mature quantum computers to emerge, researchers have developed hybrid classical/quantum algorithms to extract the most performance -- and potentially quantum advantage -- from today's noisy, error-prone hardware. |
| Effectively removing CO2 from the atmosphere Posted: 13 Aug 2021 07:02 AM PDT Researchers have investigated the extent to which direct capture of carbon dioxide (CO2) from the ambient air can help to effectively remove greenhouse gases from the atmosphere. The result: With careful planning, for example with regard to location and provision of the necessary energy, CO2 can be removed in a climate-effective manner. |
| Best of both worlds — Combining classical and quantum systems to meet supercomputing demands Posted: 12 Aug 2021 01:19 PM PDT Quantum entanglement is one of the most fundamental and intriguing phenomena in nature. Recent research on entanglement has proven to be a valuable resource for quantum communication and information processing. Now, scientists have discovered a stable quantum entangled state of two protons on a silicon surface, opening doors to an organic union of classical and quantum computing platforms and potentially strengthening the future of quantum technology. |
| Novel nanotechnology found to enhance fight against colorectal cancer and melanoma Posted: 12 Aug 2021 09:31 AM PDT Researchers recently completed a study that has the potential to improve cancer treatment for colorectal cancer and melanoma by using nanotechnology to deliver chemotherapy in a way that makes it more effective against aggressive tumors. |
| Posted: 12 Aug 2021 07:34 AM PDT We often say that a substrate fits into its enzyme like a key in a lock, but this metaphor is imperfect. Substrate binding can also change the lock (the structure of the enzyme) to induce a perfect fit. An international team of researchers has now introduced a non-biological, crystalline material that demonstrates induced-fit binding behavior when it highly selectively takes up acetylene into its pores. |
| Low-cost 3D method rapidly measures disease impacts on Florida’s coral reefs Posted: 12 Aug 2021 06:27 AM PDT A low-cost and rapid 3D technique is helping scientists to gain insight into the colony- and community-level dynamics of the poorly understood stony coral tissue loss disease responsible for widespread coral death throughout the Tropical Western Atlantic. They adapted Structure-from-Motion (SfM) photogrammetry to generate 3D models for tracking lesion progression and impacts on diseased coral colonies. They combined traditional diver surveys with 3D colony fate-tracking to determine the impacts of disease on coral colonies throughout Southeast Florida. |
| Pancreatic beta-cell boost in mice paves way for future diabetes treatments Posted: 11 Aug 2021 02:52 PM PDT A research team has uncovered the role of a gene that is critical to boosting the number of insulin-producing cells during the early development of the pancreas. Experiments with mouse models revealed that inhibiting the gene at the early embryonic stage doubles the number of insulin-producing cells, with cells maintained into adulthood and all mice showing normal weight. The findings could bolster diabetes research efforts and eventually lead to new replacement therapies for the disease. |
