POSTECH Professor Chulhong Kim's team develops high-speed rotational scanning PACT system for monitoring whole-body biodynamic.

New research reveals for the first time how a major Antarctic ice shelf has been subjected to increased melting by warming ocean waters over the last four decades.

Scientists from the University of East Anglia (UEA) say the study - the result of their autonomous Seaglider getting accidentally stuck underneath the Ross Ice Shelf - suggests this will likely only increase further as climate change drives continued ocean warming.

A new study presents a breakthrough in energy storage by introducing vanadium doping to lithium-rich layered oxides. This modification significantly enhances oxygen redox reversibility, improving voltage stability and boosting initial Coulombic efficiency to 91.6%. The vanadium-doped material addresses key issues in lithium-ion batteries, such as low efficiency and rapid voltage decay, making it a promising solution for next-generation battery technologies. These advancements offer a clear pathway for overcoming existing challenges in high-energy storage systems, particularly in applications like electric vehicles and renewable energy storage.

As air temperatures stay elevated through fall months, people may still want clothes that cool them down while outside, especially if they live in cities that stay warmer than rural landscapes. Researchers who previously demonstrated a cooling fabric coating now report on additional tests of a treated polyester fabric in ACS Applied Materials & Interfaces. Fabric treated with the team’s chalk-based coating kept the air underneath up to 6 degrees Fahrenheit cooler in warmer urban environments.

Atmospheric aerosol particles are essential for the formation of clouds and precipitation, thereby influencing the Earth’s energy budget, water cycle, and climate. However, the origin of aerosol particles in pristine air over the Amazon rainforest during the wet season is poorly understood. A new study, led by the Max Planck Institute for Chemistry in Mainz, reveals that rainfall regularly induces bursts of newly formed nanoparticles in the air above the forest canopy.
