A new study published in Nature Medicine has identified key risk factors that increase the likelihood of individuals developing multiple non-communicable diseases. The analysis found that underlying biological links exist in individuals with multimorbidity, which is a growing public health challenge. The researchers also identified pot...
A new modification strategy regulates pore size distribution and electronegativity in polyamide NF membranes, improving rejection rates for monosaccharides and monovalent salts. This results in better separation efficiency with only minor permeability loss.
Research at ETH Zurich found that defaulting to green electricity increased demand by over 80% in private households, with a significant impact on business customers as well. Despite higher costs, the majority of customers stuck with green options, demonstrating the lasting effect of default settings.
Scientists have found a way to reduce energy consumption in deep neural networks, paving the way for more efficient AI hardware. The approach uses simple electrical impulses instead of complex numerical values, maintaining high accuracy.
Researchers at Shinshu University have developed an acoustic cloaking structure that can operate in both air and water. The design uses finite element analysis to optimize the material selection and acoustics properties, enabling functionality in a wide frequency band.
Researchers at Oak Ridge National Laboratory have successfully extracted the rare and valuable isotope promethium-147 from plutonium waste. This process not only reduces disposal costs but also provides a new source of the isotope, which has applications in nuclear batteries, medical imaging, and space exploration.
A University of Illinois study suggests that India's rice farmers can increase production while reducing water usage by adopting conservation practices like direct-seeding and soil conservation technology. The researchers also recommend reducing post-harvest losses to further increase crop availability.
Scientists have proposed an effective approach to achieve full Poincaré sphere polarizers in one step using monolayer metasurfaces with arbitrary polarization conversion dichroism. The system can generate an arbitrarily polarized beam at any position on the Poincaré sphere, making it a monolithic arbitrary polarization generator.
Researchers at the Arecibo Observatory have developed a technique to analyze radar signals bounced off asteroids' surfaces, providing crucial information on their physical properties. This method can help planetary defense prepare for asteroids on a collision course with Earth by identifying porous, fluffy, or rocky surfaces.
Research suggests star clusters like Cygnus Cocoon can accelerate particles to petaelectronvolts, defying supernova theory. Theoretical models propose proton acceleration and search for lower-energy counterpart emission using NASA telescopes.
Researchers from Children's Hospital of Philadelphia have determined the process of lung alveolus formation and identified signaling hubs that coordinate cell development. The study provides crucial insights into developing therapies to regenerate critical lung tissue and repair damaged tissue at a cellular level.
A recent study published in JAMA Surgery found that patients have a more difficult time understanding and building trust with their surgeons when they cannot see the surgeon's entire face due to masking requirements. Patients reported improved communication and higher ratings for surgeons who wore clear masks.
