Astronomers have discovered heavy water in a young star’s disk, revealing that the water forming new planets is ancient and inherited from interstellar clouds. For decades, scientists have debated a profound question: Where does a planet’s water really...

device operates on a diurnal cycle. During cooler, humid nights the MOF cartridge is exposed to ambient air, allowing water vapor to enter the pores. Sunlight heats the material by day, prompting the bound water to desorb as vapor, which is then...

Plateau, Losses Elsewhere The redistribution of moisture was uneven. Atmospheric currents carried a portion of the extra water vapor away from the sites of evapotranspiration, altering precipitation patterns across the nation. The study found that the...

where water might be temporarily shielded. The concept hinges on the ability of certain hygroscopic salts to pull water vapor from Mars’ thin atmosphere. While any exposed liquid would evaporate rapidly under current conditions, cracks within mineral...

Discover lab tests assessing proximal and distal tubular function. Explore their significance in diagnosing renal disorders. These diagnostic assessments are designed to evaluate the performance of two crucial components of the kidney – the proximal...

detailed in Nature Communications, provide a compelling, though not yet definitive, explanation for the presence of water vapor previously observed in the star’s inner disk. While researchers caution that further investigation is required to confirm the...

are persistent pathways formed by a blend of sea breezes, low‑level jets and larger‑scale atmospheric rivers, allowing water vapor to travel thousands of kilometres. Building on earlier work that traced moisture from Scandinavia to Madagascar, the...

Early Microbial Life: Contextualizing the emergence of life through the lens of Earth’s earliest microbial environments. Water vapor in primordial haloes. Dense clumps with much higher water masses are visible as the yellow specks in the centers of both...

At first glance, that might not seem dramatic. But physics tells us something important. Warmer air can hold more water vapor. Roughly speaking, for every degree Celsius of warming, the atmosphere can hold about 7 percent more moisture. More moisture...

or prohibitively expensive. Jia’s approach relies on the fundamental physics of condensation, a process where atmospheric water vapor shifts into a liquid state when it encounters a temperature gradient. Engineering Water From Thin Air At the heart of...

releasing water, appeared to exceed one. That suggests that icy grains in the coma were also contributing to the observed water vapor. By 2017, the active fraction had dropped to about 0.14. That is a major decrease. This tells us that the comet’s...

A routine thermal‑spring survey led scientists deep into a mountain cave, where they uncovered a hidden underground lake hundreds of feet below. Beneath the southern Albanian border with Greece, scientists have identified a massive thermal lake that...

low enough for exposed ice to undergo direct sublimation, this increased reflectivity has profound implications for how water vapor enters the atmosphere. A brighter surface prevents the rapid, heat-driven vaporization that would occur if the ice were...

Tiny salt fractures on Mars could act as microscopic havens, trapping liquid water and potentially providing a protected environment for microbial life. Microscopic fissures within Martian salt crystals may offer a temporary sanctuary for microbial...

of comets. Instead, the research suggests these bodies formed near the “water-ice line,” a crucial thermal boundary where water vapor transitioned into ice. In this region, materials from the inner and outer solar system converged, with ice acting as a...

These trails are formed when hot exhaust gases from jet engines mix with the cold air in the upper atmosphere. As the water vapor in the exhaust gases condenses, it forms ice particles that can persist in the sky for several hours. Contrails have been a...

it forms closer to the star, it may reflect a different chemical balance. By measuring molecules such as carbon dioxide, water vapor, carbon monoxide, and methane, astronomers can estimate atmospheric carbon-to-oxygen ratios. These values help...

were cold enough for carbon dioxide to freeze into solid ice. Adding to the mystery, JWST detected relatively little water vapor compared to carbon-based gases. This could mean the comet’s interior prevents heat from reaching its icy core, limiting how...

A powerful drought in 2023 weakened the Amazon’s ability to absorb carbon dioxide, briefly turning the world’s largest rainforest into a net source of carbon. The Amazon rainforest is often called the lungs of the planet. That phrase is not...

Laser scanning of Qin Shi Huang’s sealed tomb uncovers a mysterious signal, potentially confirming a 2,000‑year‑old imperial secret hidden beneath. Deep beneath a pyramid‑shaped mound near Lintong, roughly thirty kilometres northeast of Xi’an, an...
