A new study published in Engineering uncovers the dual-faced effects of elevated CO2 on food security. It shows that while elevated CO2 can bring certain benefits to plants, it also poses threats such as reducing nutrient content in crops, which may impact global food supplies and human health.
Cellular metabolism plays a critical role in various physiological and pathological processes. High resolution imaging of intracellular metabolic activities is crucial for understanding many biological pathways, and for facilitating disease prognosis and treatment assessment. Raman scattering (RS) spectroscopy/microscopy, in particular stimulated Raman scattering (SRS), has emerged as a powerful imaging technology for cellular imaging with high specificity, high sensitivity, and subcellular resolution. Since its invention, SRS microscopy imaging has been extensively applied in life science for studying composition, structure, metabolism, development, and disease in biological systems. This review focuses on the latest applications of SRS imaging, particularly with heavy water probing, for studying metabolic dynamics of biomolecules in organisms during aging and diseases. Furthermore, future applications and development of SRS imaging in both life science and medicine are considered.
As global temperatures rise, the ability to understand how plants respond to heat has never been more critical.
A cutting-edge humidity sensing system has been unveiled, capable of monitoring human behaviors in real-time through the detection of respiratory patterns.
Long-term and precise intracellular signal detection is critical for advancing our understanding of brain diseases and developing effective diagnostic tools.
A new fully automated in vivo screening system (AISS) has been developed to transform drug evaluation by enabling rapid, precise, and non-invasive multi-organ imaging in zebrafish. Integrating cutting-edge microfluidic technology with computer-vision-based control, this innovative system automates every aspect of zebrafish larvae handling— from loading and encapsulation to immobilization and drug exposure.
A recent study reveals how the expansion and functional divergence of terpene synthase genes (TPSs) in flowering plants (angiosperms) have driven the astonishing diversity of terpenes—critical compounds involved in plant defense, floral scents, and fruit flavors.
As climate change and population growth increase pressure on global food production, regional-scale crop growth and associated process (CROP-AP) models have become essential tools for understanding and predicting agricultural productivity. A new review, published in Science China Earth Sciences, categorizes these models into four types—statistical models, crop growth models, hydrology-crop coupling models, and ecosystem models. The study explores their main functions from five aspects: crop yield prediction, crop water consumption, agricultural non-point source pollution, greenhouse gas emissions, and climate change impact and responses, and identifies key future research directions, including model validation and calibration, the ability to simulate the coupling of crop physiology and human activities, enhancing model scalability, multi-model ensembles, data and code sharing, and the integration of artificial intelligence.
