A new study reveals that soil moisture stress has a more significant impact on vegetation growth in Eurasian drylands than atmospheric vapor pressure deficit. The research provides crucial insights for effective ecosystem management and drought mitigation in the region.
The researchers developed an extreme wettability surface that enables controlled evaporation, directional bouncing, and transport of droplets on it. The surface can be used to study biochemistry, microfluidic systems, cell culture, and energy harvesting and utilization.
A new Stanford University study reveals that communities near the West's wildland-urban interface are vulnerable to wildfires due to drought-sensitive ecosystems. The research identifies 18 'double-hazard' zones where plant-water sensitivity and atmospheric dryness create high wildfire risks.
KAUST researchers have found that even low-speed solid-liquid impacts can cause cavitation and generate damaging shock waves. This challenges previous assumptions about the effects of such impacts. The team used high-speed cameras to study the impact of a flat-bottomed cylinder on a pool of liquid, observing that pressures below a cert...
In a new study, desert shrubs in the Southwest have increased their water use efficiency at unprecedented rates to survive a decades-long megadrought. The study found that despite this heroic increase, shrubs may not be adapting quickly enough to long-term drying trends in the West.
The 2018 Four Corners drought in the US was exacerbated by human-induced warming, with temperatures rising 2 degrees Celsius. The region's vegetation turned brown due to increased evaporation, resulting in economic losses of over $3 billion and impacts on Native American communities.
A new study predicts that Midwestern corn growers will require irrigation as temperatures rise and crop yields increase, posing risks to local water sources.
