Terrestrial laser scanning for monitoring hydrological cycle of trees
Water is an essential element for all living things. Understanding the dynamics of water in trees is crucial for understanding the consequences of climate change and altered water availability for forest ecosystems. A joint research project with Samuli Junttila PhD, and Professor Masato Katoh of Shinshu University's Institute for Mountain Science and others demonstrates a new laser scanning based method that can be used to monitor changes in leaf water content of tree communities.

Water is a probable vector for mammalian virus transmission
Water is a necessity for all life but its availability can be limited. In geographical areas experiencing dry seasons, animals congregate near the few freshwater sources, often reaching large densities. These sites may be key locations for pathogen transmissions, if viruses remain stable and infectious in water. A team of researchers led by Leibniz-IZW now confirmed this in a study, published in ''Science of the Total Environment''. (2021-02-15)

The water surface is a fantastic place for chemical reactions
Using an advanced technique, scientists from the RIKEN Cluster for Pioneering Research have demonstrated that a chemical reaction powered by light takes place ten thousand times faster at the air-water interface--what we usually call the water surface--than in the bulk of the water, even when the light has equivalent energy. This finding could help our understanding of the many important chemical and biological processes that take place at the water surface. (2021-02-15)

Nitrate in maternal drinking water may impair fetal growth
Women whose household drinking water contained nitrate had babies that weighed, on average, 10 grams less than babies born to mothers where household water had no detectible nitrate, according to a new study. Even low nitrate levels -- about half of the allowable level set by the US Environmental Protection Agency, or EPA -- caused an adverse effect. (2021-02-09)

Testing the waters: Analyzing different solid states of water on other planets and moons
Aside from regular ice, water can exist in the form of peculiar solids called clathrate hydrates, which trap small gaseous molecules. They play a large role in the evolution of atmospheres, but predicting their presence in cryogenic temperatures is difficult. In a recent study, scientists from Okayama University developed statistical mechanics theory to determine their presence in Pluto and some of Jupiter's and Saturn's satellites, providing valuable information to revise existing interpretations.

Power, water and climate
As the planet continues to warm, the twin challenges of diminishing water supply and growing energy demand will intensify. But water and energy are inextricably linked. For instance, nearly a fifth of California's energy goes toward water-related activities, while more than a tenth of the state's electricity comes from hydropower. As society tries to adapt to one challenge, it needs to ensure it doesn't worsen the other. (2021-01-07)

Hawai'i drought during El Niño winter? Not always, according to new research
El Niño events have long been perceived as a driver for low rainfall in the winter and spring in Hawai'i, creating a six-month wet-season drought. However, a recent study by researchers in the University of Hawai'i at Mānoa revealed the connection between Hawai'i winter rainfall and El Niño is not as straightforward as previously thought.

How water helps the substrate into the enzyme
Researchers from Bochum and Berkeley have investigated why cages can increase the catalytic activity of enclosed molecules. Using terahertz spectroscopy and complex computer simulations, they showed that water encapsulated in a tiny cage has special properties - that are structurally and dynamically distinct from any known phase of water. The water forms a droplet inside the cage that facilitates the encapsulation of a host molecule, i.e. to access the catalytic centre. (2020-12-15)

Water may be an effective treatment for metabolic syndrome

Evapotranspiration in an arid environment
Evapotranspiration is an important process in the water cycle because it is responsible for 15% of the atmosphere's water vapor. Without that input of water vapor, clouds could not form, and precipitation would never fall. It is the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants. (2020-12-15)

The greening of the earth is approaching its limit
Vegetation has a key role in mitigating climate change because it reduces the excess CO2 that we humans emit into the atmosphere. Just as when sportsmen and women are doped with oxygen, plants also benefit from the large amounts of CO2 that accumulate in the atmosphere. If more CO2 is available, they photosynthesize and grow more, which is called the fertilizing effect of CO2. (2020-12-10)
