Over the past two decades, satellite-based planetary observations have recorded rapid mass loss of Patagonian glaciers, contributing approximately 0.07 mm per year to global sea-level rise. A study published in Nature Communications links this mass loss to a poleward shift of subtropical high-pressure systems. This large-scale atmospheric circulation change brings more warm air to Patagonia, thereby accelerating glacier melt.
Addressing the challenges of fragrance design, researchers at Institute of Science Tokyo have developed an AI model that can automate the creation of new fragrances based on user-defined scent descriptors. The model uses mass spectrometry profiles of essential oils and corresponding odor descriptors to generate essential oil blends for new scents. This breakthrough is a game-changer for the fragrance industry, moving beyond trial-and-error, enabling rapid and scalable fragrance production.
Researchers in Shanghai have developed a high-efficiency cryomodule with high quality factors, promising enhanced performance and accessibility for particle accelerator applications in healthcare, industry, and scientific research.
QUT researchers have identified a new material which could be used as a flexible semiconductor in wearable devices by using a technique that focuses on the manipulation of spaces between atoms in crystals.
Dr. Pushkar Lele received a National Institute of General Medical Sciences research grant to investigate how bacteria sense their mechanical environment.
The PREPSOIL Assessment Form for Soil Health Living Lab and Lighthouse Initiatives is now live! As part of an ongoing effort to enhance the mapping and development of soil-related Living Labs (LL) and Lighthouses (LH), PREPSOIL is excited to introduce a new pre-screening assessment tool to evaluate the maturity of these initiatives.
We invite all relevant initiatives to register and complete the assessment online by 30 of April. The process is quick and straightforward, requiring only 5-10 minutes to complete.
