Toxic "forever chemicals" accumulate above the water table
PFAS (per- and polyfluoroalkyl substances) are water-, stain-, and heat-resistant chemicals added to products like nonstick pans, nail polish, food wrappers, and firefighting foam. They have been linked to health problems, including thyroid disease,.....»»
Meet the microbes that transform toxic carbon monoxide into valuable biofuel
Microbes are hungry, all the time. They live everywhere, in enormous numbers. We might not see them with the naked eye, but they are in soils, lakes, oceans, hydrothermal vents, our homes, and even in and on our own bodies. And they don't just hang o.....»»
Report on global water resources: Conditions in 2023 were either too dry or too wet
Not only was 2023 characterized by unprecedentedly high temperatures but also by excessive droughts in many parts of the world as well as floods in other areas. The World Meteorological Organization (WMO) has now presented its third report on the sta.....»»
Curiosity rover provides new insights into how Mars became uninhabitable
NASA's Curiosity rover, currently exploring Gale crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life—with evidence for widespread liquid water on the surface—to a surface that is.....»»
Drowned by hurricane, remote N.Carolina towns now struggle for water
Nicole Crane, exhausted, tearful and unwashed after a week of searching for a neighbor swept away by the raging waters of Hurricane Helene, dreams of taking a shower......»»
Flash flooding kills three in northern Thailand
Flash flooding in popular Thai tourist hotspot Chiang Mai has killed three people, a health official said Sunday, as visitors evacuated hotels through knee-high muddy water and shops closed in the city center......»»
The Secret Alchemy of Making Ice Cream
Ice cream is deceptively simple, but that sweet burst of flavor and soft melt on the tongue is a finicky, frozen science of water, fat, and air delicately held together......»»
Electricity-driven catalyst offers climate-neutral methane production
Researchers at the University of Bonn and University of Montreal have developed a new type of catalyst and used it in their study to produce methane out of carbon dioxide and water in a highly efficient way using electricity. Methane can be used, for.....»»
Qualitative study examines how ordinary people "sense" water quality
Seeing—and tasting—is believing: A qualitative study of communities living along the Philippines' bustling Marikina River underscores the importance of taking into account local peoples' everyday experiences, practices, and perceptions in establi.....»»
Scientists offer a detailed look at the skeleton of an ancient predator that thrived in extreme conditions
Imagine a world on the brink of collapse: volcanic eruptions spewing toxic gases, oceans turning acidic, and up to 90% of Earth's species vanishing in the blink of an eye. This was the reality at the end of the Permian Period, around 252 million year.....»»
Study sheds light on limitations of zooplankton for inactivating pathogen contaminated water
Scientists at The University of Texas at El Paso and Stanford University were recently surprised to find that the natural community of zooplankton—tiny, aquatic animals known to graze on bacteria—present in freshwater and saltwater do not clean w.....»»
The medicines we take to stay healthy are harming nature. Here"s what needs to change
Evidence is mounting that modern medicines present a growing threat to ecosystems around the world. The chemicals humans ingest to stay healthy are harming fish and other animals......»»
Mathematicians and climate researchers build new models for understanding polar sea ice
Polar sea ice is ever-changing. It shrinks, expands, moves, breaks apart, reforms in response to changing seasons, and rapid climate change. It is far from a homogenous layer of frozen water on the ocean's surface, but rather a dynamic mix of water a.....»»
Mexico leader worried about drinking water after Hurricane John
Mexico's new President Claudia Sheinbaum on Wednesday expressed concern about supplies of drinking water in the country's west after Hurricane John hit the Pacific coast, killing at least 16 people......»»
Why PFAS-enriched foam is forming on some of the cleanest lakes in the country
A curious phenomenon springs up occasionally on New York's Finger Lakes: white foam, sometimes in miles-long swathes, almost as if a massive washing machine emptied out into the water......»»
As temperatures rise, researchers identify mechanisms behind plant response to warming
Microscopic pores on the surface of leaves called stomata help plants "breathe" by controlling how much water they lose due to evaporation. These stomatal pores also enable and control carbon dioxide intake for photosynthesis and growth......»»
Report: Global drought threatens food supplies and energy production
In July 2024, global temperatures reached unprecedented levels, breaking historical records with an average of 17.16°C. This extreme heat has led soil water to evaporate, leaving the vegetation and biodiversity more fragile and under stress in many.....»»
Chemist challenges traditional views on crystal growth
Remember that old high school chemistry experiment where salt crystals precipitate out of a saltwater solution—or maybe the one where rock candy crystals form from sugar water? It turns out that your understanding of how crystals formed in those so.....»»
Demonstrating how Great Barrier Reef water quality targets can be achieved through gully remediation
A new study conducted at Bonnie Doon Creek on the lower Burdekin River in Queensland has demonstrated a significant reduction in sediment yield through large-scale remediation of alluvial gullies. The findings are published in the journal Internation.....»»
Unraveling the mystery of dormancy in food pathogens for more effective elimination
Listeria monocytogenes, a bacterium that causes listeriosis, a serious disease, can go into dormancy when confronted with environmental stress, for example in the presence of detergents or in water devoid of nutrients. It then becomes undetectable by.....»»
Beyond "one pore at a time": New method of generating multiple, tunable nanopores
Nanoporous membranes with atomic-scale holes smaller than one-billionth of a meter have powerful potential for decontaminating polluted water, pulling valuable metal ions from the water, or for osmotic power generators......»»
