Xinjiang's snowpack serves as a seasonal water reservoir, affecting agriculture and mountain-oasis systems. The region experienced an increase in warm-dry snow droughts after 2000, driven by both warming and precipitation deficits.
The MountAInWater project uses a unique combination of field work, modeling, and AI to assess climate change impacts on mountain water supplies and identify potential tipping points. The global reanalysis will provide crucial resources for managing future water security challenges.
A new mathematical framework, STIV, can predict larger-scale effects like proteins unfolding and crystals forming without costly simulations or experiments. The framework solves a 40-year-old problem in phase-field modeling, allowing for the design of smarter medicines and materials.
Researchers at Pohang University of Science & Technology experimentally demonstrated the existence of nanometer-sized liquid clusters in supercritical fluids, overturning the prevailing notion of a single phase. These clusters persisted for up to an hour and have significant implications for industrial processes and natural environments.
A team from Osaka Metropolitan University has developed a crystal patterning method that controls the position and orientation of photochromic crystals, known as diarylethenes. This breakthrough allows for the creation of convex structures with precise control over crystal shape and size.
A new study by Rice University astrophysicist André Izidoro suggests that the sun had rings before planets formed, explaining many solar system features. The model simulates the solar system's formation hundreds of times and reproduces several features missed by previous models, including pressure bumps and rings.
Researchers have successfully replicated the 'Zen stone' phenomenon, where stones are naturally placed atop pedestals of ice, shedding light on sublimation's influence. This process, which changes solid to gaseous form without a liquid intermediary, is revealed to shape natural structures in unique ways.
The study found that dry ice sublimation can form unique radial systems on Mars' surface, similar to spiders. The experiments showed that the Leidenfrost Effect plays a crucial role in eroding the spider patterns, which were more branched with finer grain sizes.
Researchers propose that volatile outgassing led to the flattening shape of Arrokoth, a small Kuiper Belt object. The study suggests sublimation mass loss could be a ubiquitous process shaping KBOs' structures.
Researchers used computer modeling to refine graphite's melting curve, finding it actually undergoes sublimation. Graphene was found to 'melt' into a gaseous state, enabling better understanding of phase transitions in low-dimensional materials.
Scientists predict 15-meter-tall sharp ice formations on Europa's surface could pose a hazard for future landing missions. The unique conditions on the moon create perfect conditions for these structures to form, which could be observed by NASA's upcoming Europa Clipper mission.
Scientists discover that temperature inversions and low-level atmospheric phenomena isolate the ice surface from the atmosphere, recycling water vapor and halting loss or gain of ice. This process, known as boundary-layer recycling, occurs in the center of Greenland's ice sheet and is surprisingly efficient.
Engineers from Penn and Sandia National Laboratories demonstrate the formation of interconnected carbon nanostructures on graphene substrate using a simple assembly process. The discovery may lead to new approach of graphene-based electronic devices.
