Hoodoos -- key to earthquakes?

Researchers studied two hoodoos in Red Rock Canyon to estimate the force necessary to break sandstone shafts, shedding light on ground motion during recent earthquakes. The study suggests median or low-level ground motion despite large quakes in the area, providing valuable constraints for probabilistic seismic hazard assessments.

Study offers new tool for incorporating water impacts into policy decisions

A new framework developed by researchers at the University of Minnesota provides a tool for assessing and valuing the services clean water provides, including recreation, beauty, navigation, and hydropower. The framework can be applied to on-the-ground decisions around water issues, yielding a more accurate picture of costs and benefits.

Cleaner fracking

New water treatment firms are developing chemical treatments and evaporators to remove contaminants from fracking wastewater, which can then be reused. The cost of disposal is spurring oil and gas companies to adopt these technologies, limiting the amount of contaminated water that reaches people, plants, and animals.

Nature inspires new submarine design

Researchers studied the water boatman's hind wings, which exhibit superhydrophobicity, playing a crucial role in its swimming, breathing, and balance. The study reveals that the insect's wing surface contains low surface energy materials, creating a hierarchical structure that enables it to swim freely and escape easily from water.

Scientists correct Amazon water level gauges from space

The University of Bristol scientists developed a technique to calibrate six Amazon gauges using ICESat elevation data, correcting large discrepancies in water levels. This method enables researchers to accurately estimate water levels and river slope, crucial for understanding the exchange of water with floodplains and other processes.

Sunlight plus lime juice makes drinking water safer

Researchers found that adding lime juice to water treated with solar disinfection removed detectable levels of E. coli significantly faster than solar disinfection alone. The treatment time was comparable to boiling and other household methods, making it a potential effective solution for improving water quality in low-income regions.

The Blue Planet's new water budget

Scientists at University of Copenhagen have reconstructed the isotopic composition of 3.8 billion-year-old seawater, revealing that young planet's oceans had proportionately more 'normal water' than 'heavy water'. This discovery suggests Earth has lost less than ¼ of its water budget over the last roughly 4 billion years.

Millennium Development Goals progress reports overestimate access to safe water

A study by University of Bristol researchers found that relying solely on improved water source type oversimplifies the measure of safety, leading to substantial underestimations in four developing countries. The adjustment increased estimates of people without access to safe drinking water in Ethiopia and Nigeria by millions.

Supercool

Researchers found that water changes its molecular structure to form 'intermediate ice' at -55 F, allowing it to remain liquid below the traditional freezing point. The discovery sheds light on atmospheric scientists' need to predict global climate patterns and how much solar radiation is absorbed by atmospheric water and ice.

When water and air meet

Researchers have resolved a long-standing debate over water molecules at the air-water interface, finding strong hydrogen bonding between water pairs at the outermost surface. The study uses theoretical and experimental techniques to pinpoint the origin of water's unique surface properties.

Extremely rapid water: RUB scientists decipher a protein-bound water chain

Researchers from RUB-Department of Biophysics elucidated the proton pump mechanism of a cell-membrane protein in atomic detail, revealing that protein-bound water molecules play a decisive role. A chain of only three water molecules is formed for just a few thousandths of a second to transfer protons into the interior of the protein.
