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.....»»

"Video game ecology" can help us understand the climate crisis in our forests
When we think of climate change we often think of extreme events like flooding rains and large bushfires. But climate change can also have slower, more subtle impacts on our landscapes......»»
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.....»»
New climate chemistry model finds "non-negligible" impacts of potential hydrogen fuel leakage
As the world looks for ways to stop climate change, much discussion focuses on using hydrogen instead of fossil fuels, which emit climate-warming greenhouse gases (GHGs) when they're burned. The idea is appealing. Burning hydrogen doesn't emit GHGs t.....»»
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.....»»
How much permafrost will melt this century, and where will its carbon go?
Among the many things global warming will be melting this century—sea ice, land glaciers and tourist businesses in seaside towns across the world—is permafrost. Lying underneath 15% of the northern hemisphere, permafrost consists of accumulating.....»»
Southern states brace for water changes, report finds
Water is everywhere. It falls freely from the sky and flows across the earth. Humans are inextricably connected to water and to forests. Changes in land use, forest conditions, and climate affect water – with consequences for drinking water treatme.....»»
Floods, insufficient water, sinking river deltas: Hydrologists map changing river landscapes across the globe
A study in Science by researchers from the University of Massachusetts Amherst and University of Cincinnati has mapped 35 years of river changes on a global scale for the first time......»»
Single heat wave wiped out millions of Alaska"s dominant seabird
The common murre, a large black-and-white seabird native to northern waters, has become far less common in Alaska over the past decade due to the impacts of climate change......»»
Study finds catch-and-release affects giant trevally behavior
In an effort to conserve sensitive species of fish, some sport fishing is entirely catch-and-release, meaning that the fish are returned to the water once brought ashore. However, too much fishing may affect the behavior of the target species and th.....»»
Alberta"s lifting of restrictions on wolverine trapping could spell disaster for a declining population
You never forget encountering your first wolverine. Mine was on the top of Grande Mountain outside Grande Cache, Alta., on a brilliant winter morning. It roared at me from the thick alpine bushes, then fled unseen into the wilderness. That exhilarati.....»»
"Zero progress": Western states at impasse in talks on Colorado River water shortages
Seven Western states that depend on the Colorado River are ending the year at an impasse in negotiations over the writing of new rules for dealing with chronic water shortages......»»
Researchers call on European Commission to protect groundwater and subterranean life from pollution
The subterranean world holds a value that is often underestimated. Its significance seems to escape notice, particularly its vital role in storing drinking water—a resource long taken for granted—and its contribution to biodiversity, harboring un.....»»
Illegal ritualistic hunts in West Bengal kill thousands of animals each year
A new study in the journal Nature Conservation highlights the grave impacts of illegal ritualistic hunts in West Bengal, India, where thousands of hunters gather during cultural or religious festivals to kill wildlife using traditional weapons such.....»»

Less is more: Why an economical iridium catalyst works so well
Iridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the iridium, is as efficient and stable over time as the best commer.....»»
