Published How Saharan dust regulates hurricane rainfall



New research underscores the close relationship between dust plumes transported from the Sahara Desert in Africa, and rainfall from tropical cyclones along the U.S. Gulf Coast and Florida.
Published Drawing water from dry air



A prototype device harvests drinking water from the atmosphere, even in arid places.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation



Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
Published 3D-printed microstructure forest facilitates solar steam generator desalination



Faced with the world's impending freshwater scarcity, researchers turned to solar steam generators, which are emerging as a promising device for seawater desalination. The team sought design inspiration from trees and harnessed the potential of 3D printing. They present technology for producing efficient SSGs for desalination and introduces a novel method for printing functional nanocomposites for multi-jet fusion. Their SSGs were inspired by plant transpiration and are composed of miniature tree-shaped microstructures, forming an efficient, heat-distributing forest.
Published Researchers enhance tool to better predict where and when wildfires will occur



A newly enhanced database is expected to help wildfire managers and scientists better predict where and when wildfires may occur by incorporating hundreds of additional factors that impact the ignition and spread of fire.
Published Aluminum scandium nitride films: Enabling next-gen ferroelectric memory devices



Aluminum scandium nitride thin films could pave the way for the next generation of ferroelectric memory devices, according to a new study. Compared to existing ferroelectric materials, these films maintain their ferroelectric properties and crystal structure even after heat treatment at temperatures up to 600 C in both hydrogen and argon atmospheres. This high stability makes them ideal for high-temperature manufacturing processes under the H2-included atmosphere used in fabricating advanced memory devices.
Published 3D printing of light-activated hydrogel actuators



An international team of researchers has embedded gold nanorods in hydrogels that can be processed through 3D printing to create structures that contract when exposed to light -- and expand again when the light is removed. Because this expansion and contraction can be performed repeatedly, the 3D-printed structures can serve as remotely controlled actuators.
Published Scientists use AI to predict a wildfire's next move



Researchers have developed a new model that combines generative AI and satellite data to accurately forecast wildfire spread.
Published New dawn for space storm alerts could help shield Earth's tech



Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.
Published New technique pinpoints nanoscale 'hot spots' in electronics to improve their longevity



Researchers engineered a new technique to identify at the nanoscale level what components are overheating in electronics and causing their performance to fail.
Published Researchers predict fewer, pricier strawberries as temperatures warm



Strawberries could be fewer and more expensive because of higher temperatures caused by climate change, according to new research.
Published Weather experts discover new effect of storm -- in a teacup



A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.
Published Capturing carbon with energy-efficient sodium carbonate-nanocarbon hybrid material



Carbon capture is a promising approach for mitigating carbon dioxide (CO2) emissions. Different materials have been used to capture CO2 from industrial exhaust gases. Scientists developed hybrid CO2 capture materials containing sodium carbonate and nanocarbon prepared at different temperatures, tested their performance, and identified the optimal calcination temperature condition. They found that the hybrid material exhibits and maintains high CO2 capture capacity for multiple regeneration cycles at a lower temperature, making it cost- and energy-effective.
Published Hydrogen flight looks ready for take-off with new advances



The possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies show that almost all air travel within a 750-mile radius (1200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel heat exchanger currently in development, this range could be even further.
Published New study provides enhanced understanding of tropical atmospheric waves



Findings has critical implications for predicting extreme weather events such as hurricanes and heavy rainfall.
Published Planted mangroves' ability to store carbon



Ecologists have published new findings on how planted mangroves can store up to 70% of carbon stock to that found in intact stands after only 20 years.
Published The Gulf Stream is wind-powered and could weaken from climate change



New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published Researchers show promising material for solar energy gets its curious boost from entropy



Researchers discovered a microscopic mechanism that solves in part the outstanding performance achieved by a new class of organic semiconductors known as non-fullerene acceptors (NFAs).
Published First local extinction in the US due to sea level rise, study suggests



The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published Groundbreaking study reveals oceanic seabirds chase tropical cyclones



A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
