Getting a good night’s sleep is a critical part of our daily biological cycle and is associated with improved brain function, a stronger immune system, and a healthier heart. Conversely, sleep disorders like insomnia and sleep apnea can significantly impact health and quality of life. Poor sleep often precedes the onset of neurodegenerative diseases and is a predictor of early dementia. New research appearing in the journal Cell describes for the first time the tightly synchronized oscillations in the neurotransmitter norepinephrine, ...

LA JOLLA (January 8, 2025)—Human bodies defend themselves using a diverse population of immune cells that circulate from one organ to another, responding to everything from cuts to colds to cancer. But plants don’t have this luxury. Because plant cells are immobile, each individual cell is forced to manage its own immunity in addition to its many other responsibilities, like turning sunlight into energy or using that energy to grow. How these multitasking cells accomplish it all—detecting threats, communicating those threats, and ...

Nitrogen is an essential component in the production of amino acids and nucleic acids — both necessary for cell growth and function. Although the atmosphere is composed of nearly 80% nitrogen, this nitrogen is in the form of dinitrogen (N2), which cannot be processed by most organisms. Atmospheric nitrogen must first be converted, or “fixed,” into a form that can be used by plants, often as ammonia. There are only two ways of fixing nitrogen, one industrial and one biological. To better understand a key component of the biological process, University of California San Diego Professor of Chemistry and Biochemistry Akif Tezcan and Assistant Professor of Chemistry ...

Standing dead trees in Yellowstone National Park are growing wildfire hazards, especially near park infrastructure. A new study published in Forest Ecosystems explores how these dead trees contribute to fire risk and threaten roads, buildings, and trails. Dead trees, particularly those that remain standing, are a significant fire hazard. These trees—often caused by pests, diseases, and climate change—create a large amount of dry, combustible material. As temperatures rise and droughts intensify, the risk of wildfires increases, making it essential to understand how dead trees contribute to fire danger. The team used a random forest classification model, a powerful ...

The widely used nickel-based superalloys for turbine engine materials showed a limited-service temperature of only 1200℃, and did not exceed 1500℃ even when coated with thermal barrier coatings, which is urgent to develop the advanced thermal protection system for turbine engines with higher thrust-weight ratios. Niobium alloy coated with silicide coating is undoubtedly considered the most efficient method to reach long-term service, since it can form a dense SiO2 layer with self-healing ability at high temperatures. However, the single silicide coating has a strong tendency to crack vertically ...
