Getting to the bottom of Arctic landslides
Erosion of the frozen soil of Arctic regions, known as permafrost, is creating large areas of subsidence, which has catastrophic impact in these regions sensitive to climate change. As the mechanisms behind these geological events are poorly understood, researchers from the Géosciences Paris Sud laboratory (CNRS / Université Paris-Saclay), in cooperation with the Melnikov Permafrost Institute in Yakutsk, Russia, conducted a cold room simulation of landslides, or slumps, caused by accelerated breakdown of the permafrost.

Transportation of water into the deep Earth by Al-phase D
Researchers at Ehime University have recently measured the propagation speed of ultrasonic waves in an aluminum-rich hydrous mineral called Al-phase D at pressure conditions relevant to the Earth's deep mantle. Their results suggest that seismic shear anomalies observed locally beneath subduction zones may reveal the presence of hydrous minerals in the uppermost lower mantle, which would have important implications for the Earth's interior because hydrogen affects considerably the physical and chemical properties of mantle minerals.

The neurobiology of thirst: The neural mechanisms that control hydration
Scientists at the Tokyo Institute of Technology (Tokyo Tech) provide deeper insights into neural thirst control. Their study published recently in Nature Communications indicates that cholecystokinin-mediated water-intake suppression is controlled by two neuronal 'thirst-suppressing' sub-populations in the subfornical organ in the brain; one population is persistently activated by excessive water levels, and the other, transiently after drinking water.

Climate change presents new challenges for the drinking water supply
Rising temperatures in Germany's largest drinking water reservoir present new challenges for the drinking water supply. According to a group of UFZ researchers, the impacts of this increase can be alleviated by mitigating climate change and applying new management strategies. (2020-11-23)

Researchers prove water has multiple liquid states
When water reaches approximately -63 degrees centigrade it can separate into two liquid states, with one liquid being 20% more dense than the other. This is a fundamental finding that explains many of the anomalous properties of water at low temperatures. The finding has potential implications in low-temperature chemical and biochemical processes in aqueous environments. (2020-11-19)

Two liquids of water exist
Using x-ray lasers, researchers at Stockholm University have been able to follow the transformation between two distinct different liquid states of water, both being made of H2O molecules. At around -63 Centigrade the two liquids exist at different pressure regimes with a density difference of 20%. By rapidly varying the pressure before the sample could freeze, it was possible to observe one liquid changing into the other in real time. Their findings are published in the journal Science.

'Oasis effect' in urban parks could contribute to greenhouse gas emissions, ASU study finds
Following a year of on-site analyses at a Phoenix-area park, hydrologist Enrique Vivoni of Arizona State University identified that the park showed what meteorologists call the ''oasis effect,'' a microclimate that is cooler than a surrounding dry area due to the evaporation of a water source.

US agricultural water use declining for most crops and livestock production
Agricultural production and food manufacturing account for a third of water usage in the U.S. Water use fluctuates with weather patterns but is also affected by shifts in production technology, supply-chain linkages, and domestic and foreign consumer demand. A comprehensive University of Illinois study looked at water withdrawals in U.S. agriculture and food production from 1995 to 2010. The main trend was a decline in water use, driven by a combination of factors. (2020-11-16)

A biomimetic membrane for desalinating seawater on an industrial scale
Reverse osmosis is one of the most widely used techniques for the desalination of water. Some of the membranes currently used are artificial channels of water inserted into lipid layers. But their large-scale performance is not satisfactory. An international team has developed a hybrid strategy, which consists of combining a polyamide matrix and artificial water channels into a single structure. Their membranes have been tested under industrial conditions and outperform conventional membranes. (2020-11-09)

Mystery of glacial lake floods solved

The dangers of collecting drinking water
Fetching drinking water in low and middle income countries can cause serious injury, particularly for women. A new international study published in BMJ Global Health reveals dangers including falls, traffic accidents, animal attacks, and fights, which can result in broken bones, spinal injuries, lacerations, and other physical injuries. The work draws on a survey of 6,291 randomly selected households across 24 sites in 21 low- and middle-income countries in Asia, Africa, Latin America, and the Caribbean. (2020-11-04)

CAM modes provide environment-specific water-saving benefits in a leaf metabolic model
Several plant lineages living in arid environments have evolved crassulacean acid metabolism (CAM) photosynthesis, a water-saving mode of carbon fixation in which CO2 uptake and CO2 fixation are temporally separated. Researchers from IPK Gatersleben and the University of Oxford tested whether full CAM is also necessarily the best solution for C3 crops grown in temperate environments and attempted to identify alternative metabolic modes that best balance the trade-off between water loss and photosynthetic productivity under a range of environments.
