A recent study reveals the Antarctic Intermediate Water has reversed its long-term trends in salinity and density, driven by reduced freshwater input from melting sea ice. This change could impact global ocean currents, carbon storage, and climate stability, with potential cascading effects on weather patterns and atmospheric circulation.
A team of researchers at Kyoto University identified endophytes, fungi that symbiotically inhabit plant tissue, as key species shaping forest root microbiomes. These hidden masterminds significantly influence the landscape structure of fungal communities, with implications for ecosystem management.
A new study challenges the theory that comets delivered molecular building blocks for life on Earth, finding it highly unlikely due to comets' speed and angle of impact. Mars may be a more promising candidate for cometary delivery of prebiotic molecules, but it's still a rare occurrence.
Researchers at Washington State University have discovered a feed supplement that increases honey bee colony size, addressing blueberry pollination declines. The supplement, called Nano-B-Feed, is a powdered mixture of minerals and organic compounds that bees consume to boost their population.
A team of Oxford chemists used machine learning simulations to trace the atomic-scale processes that give hard carbon its disordered structure. The study reveals how removal of hydrogen and chlorine atoms generates reactive carbon sites that form new bonds, connecting the polymer chains into an extended network.
Researchers developed a long-acting protein-based therapeutic by fusing human erythropoietin to engineered albumin, showing a 5.7-day plasma half-life and improved mucosal barrier crossing. The fusion protein maintained therapeutic function and increased red blood cell production.
The study identified a thermodynamic boundary for photocurrent generation and found that more rigid donor molecules were associated with lower radiative voltage losses. This energy relationship could help maintain photocurrent while minimizing voltage losses, providing design guidelines for more efficient organic solar cells.
Researchers have developed a new process that captures CO₂ and produces itaconic acid, a valuable bio-based chemical, using a combination of electrochemical and microbial processes. The process uses CO₂ instead of sugar as a starting material, eliminating the need to transport intermediate products.
