| Nanodiamonds are key to efficient hydrogen purification Posted: 16 Dec 2021 11:59 AM PST Researchers describe how nanodiamond-reinforced composite membranes can purify hydrogen from its humid mixtures, making the hydrogen generation processes vastly more efficient and cost-effective. |
| Artificial intelligence accurately predicts who will develop dementia in two years Posted: 16 Dec 2021 11:59 AM PST Artificial intelligence can predict which people who attend memory clinics will develop dementia within two years with 92 per cent accuracy, a largescale new study has concluded. Using data from more than 15,300 patients in the US, researchers found that a form of artificial intelligence called machine learning can accurately tell who will go on to develop dementia. |
| A quantum view of 'combs' of light Posted: 16 Dec 2021 11:59 AM PST Frequency microcombs are specialized light sources that can function as light-based clocks, rulers and sensors to measure time, distance and molecular composition with high precision. New research presents a novel tool for investigating the quantum characteristics of these sources. |
| Secret embraces of stars revealed by Alma Posted: 16 Dec 2021 11:59 AM PST Unlike our Sun, most stars live with a companion. Sometimes, two come so close that one engulfs the other -- with far-reaching consequences. When astronomers used the telescope Alma to study 15 unusual stars, they were surprised to find that they all recently underwent this phase. The discovery promises new insight on the sky's most dramatic phenomena -- and on life, death and rebirth among the stars. |
| Energy-saving glass 'self-adapts' to heating and cooling demand Posted: 16 Dec 2021 11:50 AM PST Scientists have developed a material that, when coated on a glass window panel, can effectively self-adapt to heat or cool rooms across different climate zones in the world, helping to cut energy usage. |
| How crowds can make bridges wobble and sway Posted: 15 Dec 2021 05:41 PM PST Researchers have uncovered a surprising new explanation for why pedestrian bridges can suddenly start to wobble and sway: too many people crossing at once and simply trying not to fall over. |
| Prenatal exposure to phthalates damages reproductive tissue in female mice Posted: 15 Dec 2021 05:41 PM PST Phthalates are a ubiquitous family of chemicals that are used every day. In a new study, researchers have investigated how these compounds affect tissue development in the reproductive systems of female mice offspring. |
| A robotic hand with a gecko-inspired grip Posted: 15 Dec 2021 05:40 PM PST Aiming to create a robotic gripper that can grasp with delicate strength, researchers combine adhesives based on gecko toes with a customized robotic hand. |
| Posted: 15 Dec 2021 05:40 PM PST Researchers developed a new, faster, less expensive method for screening billions of chemical compounds to find new, targeted drug therapies. |
| Nitrogen’s impact on soil carbon sequestration Posted: 15 Dec 2021 11:22 AM PST Soil organic carbon is a cornerstone of soil health. It improves soil structure while enhancing water- and nutrient-holding capacity, key factors for any agricultural production system. To build it up, farmers incorporate crop residues into soils. So why, despite decades of residue inputs, is soil organic carbon diminishing in corn production systems? Short answer: it's the nitrogen. |
| Winter is coming: Researchers uncover the surprising cause of the little ice age Posted: 15 Dec 2021 11:20 AM PST New research provides a novel answer to one of the persistent questions in historical climatology, environmental history and the earth sciences: what caused the Little Ice Age? The answer, we now know, is a paradox: warming. |
| A mathematical model may give more efficient climate talks Posted: 15 Dec 2021 11:20 AM PST Achieving consensus among countries in global climate negotiations is a long and complicated process. Researchers have developed a mathematical model that describes the achievement of the 2015 Paris Agreement and that may contribute to more efficient negotiations when striving for unanimity. |
| Soft semiconductors that stretch like human skin can detect ultra-low light levels Posted: 15 Dec 2021 11:20 AM PST Researchers have demonstrated a new photodetector material that acts like a second skin layer and is up to 200% more stretchable than its original dimension without significantly losing its electric current. The researchers say the soft flexible photodetectors could enhance the utility of medical wearable sensors and implantable devices, among other applications. |
| The heat is on: RIPE researchers show ability to future-proof crops for changing climate Posted: 15 Dec 2021 10:26 AM PST Research shows that bypassing a photosynthetic glitch common to crops like soybean, rice, and wheat, can confer thermal protection under heat stress in the field. |
