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.

Those lakes include large bays in some of the deepest of the Great Lakes, such as Lake Superior and Lake Michigan, which could permanently become ice free by 2055. (2021-01-13)

A bucket of water can reveal climate change impacts on marine life in the Arctic
We know very little about marine life in the Arctic. Now researchers from the University of Copenhagen, among others, are trying to change that. They have shown that a simple water sample makes it possible to monitor the presence, migration patterns and genetic diversity of bowhead whales in an otherwise hard-to-reach area. The method can be used to understand how climate changes and human activities impact life in the oceans. (2021-01-12)

Johns Hopkins scientist develops method to find toxic chemicals in drinking water
Most consumers of drinking water in the United States know that chemicals are used in the treatment processes to ensure the water is safe to drink.

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.

Beating the bulge with a nice cup of tea
Researchers led by the University of Tsukuba found that healthy volunteers who consumed oolong tea every day had much higher levels of fat breakdown compared with the placebo group, and that the effects were most noticeable during sleep. Importantly, the volunteers developed a tolerance to caffeine over the 2-week study period, with their sleep patterns remaining unaffected by tea or caffeine consumption, indicating that oolong tea may have clinical relevance for weight control.

Remote sensing data sheds light on when and how asteroid Ryugu lost its water
Rocks on Ryugu, a 'rubble pile' near-Earth asteroid recently visited by Japan's Hayabusa2 spacecraft, appear to have lost much of their water before they came together to form the asteroid, new research suggests. (2021-01-05)

Identifying Canada's key conservation hot spots highlights problem
To stop biodiversity loss, Canada recently committed to protecting 30% of its land and sea by 2030. But making conservation decisions about where to locate new protected areas is complicated. It depends on data both about biodiversity and about a range of benefits (e.g. freshwater, climate regulation, recreation) that people get from nature. Despite the size of the country, new mapping suggests that less than 1% of Canada's land is a hot spot, providing all these benefits in one place. (2021-01-05)

Controlling the nanoscale structure of membranes is key for clean water, researchers find
A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains complex intricacies that have baffled scientists for decades -- until now. Researchers from Penn State, The University of Texas at Austin, Iowa State University, Dow Chemical Company and DuPont Water Solutions published a key finding in understanding how membranes actually filter minerals from water, online today (Dec. 31) in Science.

Mummified baboons shine new light on the lost land of Punt
Ancient Punt was a major trading partner of Egyptians for at least 1,100 years. It was an important source of luxury goods, including incense, gold, and living baboons. Located somewhere in the southern Red Sea region in either Africa or Arabia, scholars have debated its geographic location for more than 150 years. A new Dartmouth-led study tracing the geographic origins of Egyptian mummified baboons provides new insight into Punt's location, demonstrating the tremendous nautical range of early Egyptian seafarers.

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
Researchers at the University of Colorado Anschutz Medical Campus have discovered that fructose stimulates the release of vasopressin, a hormone linked to obesity and diabetes. They also found that water can suppress the hormone and alleviate these conditions in mice. (2020-12-15)

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)
