Enhanced photoelectrochemical water splitting with a donor-acceptor polyimide
Polyimide (PI) has emerged as a promising organic photocatalyst owing to its distinct advantages of high visible-light response, facile synthesis, molecularly tunable donor-acceptor structure, and excellent physicochemical stability. However, the syn.....»»
Structural analysis reveals how human eyelashes promote water drainage
Throughout human evolution, body and facial hair have notably diminished, yet eyelashes have remained a distinguishing feature. The physiological or functional purpose of eyelashes—traditionally thought to be for catching dust or filtering air—ha.....»»
Water and gruel—not bread: Discovering the diet of early Neolithic farmers in Scandinavia
At a Neolithic settlement on the Danish island Funen dating back 5,500 years, archaeologists have discovered both grinding stones and grains from early cereals. However, new research reveals that the inhabitants did not use the stones to grind the ce.....»»
Warming exacerbates oxygen depletion in the Baltic Sea, undermining nutrient reduction efforts
Eutrophication and rising water temperatures are taking an increasing toll on the Baltic Sea, leading to dangerous oxygen depletion in deeper water layers and threatening many marine organisms. Despite successful efforts to reduce nutrient inputs, ri.....»»
Intense ribbons of rain also bring the heat, scientists say
The environmental threat posed by atmospheric rivers—long, narrow ribbons of water vapor in the sky—doesn't come only in the form of concentrated, torrential downpours and severe flooding characteristic of these natural phenomena. According to a.....»»

Apollo lunar mission samples reveal origins of lunar water and its connection to Earth"s early history
A team of international scientists has unveiled groundbreaking research on the origins of lunar water, offering insights that could reshape our understanding of the Earth-moon system and the broader solar system. Published in the journal Proceedings.....»»
Researchers unveil chip for quick antibiotic monitoring in water
Antimicrobial resistance (AMR) is a growing global health crisis because of microbes, such as bacteria, becoming resistant to antibiotics. A leading factor in this rise is the improper use and disposal of antibiotics in the environment......»»
Ancient Mars" thick crust could have supported hidden water reservoirs and rare magmas, new research suggests
A new study explores how variations in Mars' crustal thickness during its ancient history may have influenced the planet's magmatic evolution and hydrological systems. The research, published in Earth and Planetary Science Letters, suggests that the.....»»
Plumbing poverty: More people living without running water in US cities since global financial crisis
More American cities—even those seen as affluent—are home to people living without running water as people are being "squeezed" by unaffordable housing and the cost-of-living crisis, new research finds......»»
Advance in photochemical water oxidation enhances sustainable energy potential
With the global shift towards sustainable and renewable energy, the urgency to develop efficient methods for producing clean energy has never been greater. Imagine a future where the energy that powers our homes and cities comes from one of the plane.....»»
Potentially harmful bacteria can slip through antimicrobial showerheads, study finds
To guard against harmful waterborne pathogens, many consumers, including managers of health-care facilities, install antimicrobial silver-containing showerheads. But in ACS ES&T Water, researchers now report that these fixtures are no "silver bullet......»»
Research reveals how bad bacteria trigger painful gut contractions
After a meal of questionable seafood or a few sips of contaminated water, bad bacteria can send your digestive tract into overdrive. Your intestines spasm and contract, efficiently expelling everything in the gut—poop and bacteria alike......»»
Cutting-edge satellite tracks lake water levels in Ohio River Basin
The Ohio River Basin stretches from Pennsylvania to Illinois and contains a system of reservoirs, lakes, and rivers that drains an area almost as large as France. Researchers with the SWOT (Surface Water and Ocean Topography) mission, a collaboration.....»»
Permafrost thaw impacts alpine runoff and water retention
Permafrost, a unique geological phenomenon found in the Qinghai-Xizang Plateau and other high-altitude cold regions, significantly influences the generation of runoff and hydrological processes in frozen watersheds. Its ability to retain water differ.....»»
Building concrete on Mars from local materials
Imagine you've just gotten to Mars as part of the first contingent of settlers. Your first challenge: build a long-term habitat using local materials. Those might include water from the polar caps mixed with specific surface soils. They might even re.....»»
Waal river draws more water, signaling potential Rhine system shift
Historical observations and model computations point to the Rhine system having crossed a tipping point. Since extreme peak flows in the 1990s, the Waal has gradually attracted more water at the Pannerdense Kop bifurcation. This is shown in research.....»»
Yeast cell wall proteins offer possible alternative to emulsifiers derived from milk
Mention emulsifiers and many people might be unaware of what they are used for, but they are present in many daily products, from food to cosmetics. They keep substances that don't usually mix, like water and oil, from separating and are either synth.....»»
New study says we"re unlikely to find liquid water on Mars anytime soon
More than a hundred years ago, astronomer Percival Lowell made the case for the existence of canals on Mars designed to redistribute water from the Martian ice caps to its lower, drier latitudes. This necessarily meant the existence of Martians to bu.....»»
Unlocking the journey of gold through magmatic fluids
When one tectonic plate sinks beneath another, it generates magmas rich in volatiles such as water, sulfur and chlorine. As these magmas ascend, they release magmatic fluids, in which sulfur and chlorine bind to metals such as gold and copper, and tr.....»»
