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. The researchers found that the warmer atmosphere will draw more moisture from plants, necessitating a significant expansion of irrigation to maintain current yields.
Researchers have discovered a class of disordered materials that can exhibit massive cooling effects when subjected to low pressure. The materials, called plastic crystals, display extremely high entropy changes, making them ideal for emerging solid-state refrigeration technologies.
Researchers from KAUST developed nature-inspired surfaces that decrease frictional drag at the liquid-pipe interface without chemical coatings. The microtextured surfaces, mimicking springtail skins, sustain trapped air for extended periods, reducing surface drag and enhancing oil- and water-repellent properties.
Researchers at NIST have measured the vapor pressure of delta-9 tetrahydrocannabinol (THC), a fundamental property for developing accurate marijuana breathalyzers. The study uses PLOT-cryo technology to capture and analyze THC molecules, providing crucial groundwork for manufacturers.
A new molecular modeling method using freely available software provides accurate predictions of solubility. The approach exploits thermodynamic expressions and can be applied to any solute-solvent combination, making it a crucial tool for industries such as pharmaceuticals and petroleum.
AUA trauma surgeon Dr. Gary Vercruysse reports an increase in e-cigarette-related burns, highlighting the dangers of lithium-ion batteries. The study suggests that thermal runaway can cause internal damage to batteries, leading to explosions and severe burns.
Researchers at Virginia Tech developed a beetle-inspired method to control frost growth on surfaces using chemical micropatterns. By attracting water to specific areas and repelling it from others, they created dry zones around frozen dew drops, preventing frost from spreading.
Tropical Depression 9 is battling strong vertical wind shear and dry air, leading to its weakening. The depression is expected to degenerate into a remnant low pressure area in 24 hours or less due to persistent environmental conditions.
Researchers found that iron vaporization at high pressures can create an iron-rich rain that blankets the forming Earth, explaining the iron pockets in the mantle. This process challenges traditional core formation theories and changes our interpretation of geochemical data.
Scientists have developed a method to produce nanodiamonds using ethanol vapor at room temperature and pressure, requiring no surface growth. The discovery holds promise for various applications, including flexible electronics, implants, and drug delivery devices.
Researchers at NC State University have developed a new technique to create high-quality semiconductor thin films at the atomic scale. The technique enables the creation of wafer-scale MoS2 monolayer thin films with precise control over thickness, opening up possibilities for scalable production of lasers, LEDs and computer chips.
Two low-pressure areas, System 99S and System 97S, are developing near the Northern Territory and Western Australia, posing a threat to the region. These tropical systems have consolidated convection patterns and are expected to bring strong winds and heavy rainfall to coastal areas.
Coal outbursts in underground mines are among the major killers, but scientists have long been investigating their precise mechanism. New research suggests that coal outbursts occur through a process similar to explosive volcanic eruptions, driven by high gas pressure inside coal.
Researchers are developing a minimally invasive procedure to treat herniated disks, eliminating the need for incision. The new approach uses X-ray guidance to insert a needle directly into the disk, removing the problematic nucleus and providing relief from pressure on nearby nerves and inflammation.
Researchers at Penn State have developed a new model for vulcanian eruptions, which they validated using data from the Soufriere Hills volcano. The model suggests that water vapor leakage plays a crucial role in determining the rate and force of these explosive events.
