Researcher pushes limit of when water will freeze
Though it is one of the great mysteries of science, the transformation of water into ice often escapes people's minds as it is just assumed that's what happens. But how and why it happens is the subject of intense scrutiny by ice scientists.....»»
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......»»
Does limiting iPhone charging to 80% extend battery life?
Both the iPhone 16 and the iPhone 15 before it offer the option to limit charging to 80% rather than 100%. The thinking is that many people don’t need the full battery capacity of the device in a typical day, and it reduces wear on the battery, ext.....»»
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.....»»
CUPS vulnerabilities could be abused for DDoS attacks
While the Common UNIX Printing System (CUPS) vulnerabilities recently disclosed by researcher Simone “evilsocket” Margaritelli are not easily exploited for remote command execution on vulnerable systems, they could offer more opportunity.....»»
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.....»»
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......»»
The Oura Ring 4 smart ring is here, and it looks superb
The Oura Ring 4 has a new design, an updated app, and improved accuracy, as the company pushes to maintain its status as the smart ring to beat......»»
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.....»»
New materials and techniques show promise for microelectronics and quantum technologies
As phones and computers shrink in size, our need for data storage and transfer is growing. Electronic devices have been powered by semiconductors for decades, but as the push to miniaturize continues, there's a limit to how small semiconductors can b.....»»
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.....»»
Solar Sails and Comet Tails: How Sunlight Pushes Stuff Around
It seems crazy, but light actually exerts a physical force on objects. It could power a new generation of spacecraft for deep-space missions......»»
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......»»
Predicting river flow dynamics using stable isotopes for improved ecosystem health
An international science team has made significant strides in understanding river flow dynamics. The findings leverage isotope hydrology techniques such as measuring stable isotopes in water molecules to elucidate the contributions of various water s.....»»
