Sustainable hydrophobic cellulose shows potential for replacing petroleum-related products
A recent study has aimed to create hydrophobic paper by exploiting the mechanical properties and water resistance of cellulose nanofibers, and so produce a sustainable, high-performance material suitable for packaging and biomedical devices. This inv.....»»
Dams have taken half the water from Australia"s second biggest river—and climate change will make it even worse
The largest wetland on Australia's second longest river, the Murrumbidgee in the southern Murray-Darling Basin, is drying up. This is bad news for the plants, animals and people who rely on the vast Lowbidgee Floodplain. So it's important to understa.....»»
Study examines effects of Atlantic circulation on the Amazon rainforest
The Amazon region is a global hotspot of biodiversity and plays a key role in the climate system because of its ability to store large amounts of carbon and its influence on the global water cycle. The rain forest is threatened, however, by climate c.....»»
Rainwater samples reveals it"s literally raining "forever chemicals" in Miami
PFAS are in Miami's rainwater. And it is the latest evidence the synthetic "forever chemicals"—that have raised health concerns for people and wildlife—hitch a ride on the water cycle, using the complex system to circulate over greater distances......»»
Psychological inoculation: Combining two simple tools could combat election misinformation
A popular new strategy for combating misinformation doesn't by itself help people distinguish truth from falsehood but improves when paired with reminders to focus on accuracy, finds new Cornell University-led research supported by Google......»»
Not too big, not too small: Why modern humans are the ideal size for speed
The fastest animal on land is the cheetah, capable of reaching top speeds of 104 kilometers per hour. In the water, the fastest animals are yellowfin tuna and wahoo, which can reach speeds of 75 and 77 km per hour respectively. In the air, the title.....»»

International SWOT satellite spots planet-rumbling Greenland tsunami
The international Surface Water and Ocean Topography (SWOT) satellite mission, a collaboration between NASA and France's CNES (Center National d'Études Spatiales), detected the unique contours of a tsunami that sloshed within the steep walls of a fj.....»»
California"s Salton Sea receding at greater rate according to balloon mapping study
The Salton Sea, California's largest lake by surface area, is experiencing an increasing rate of shoreline retreat following a policy change that shifted more water from the Colorado River to San Diego, according to a newly published study. The resul.....»»
Forever chemicals are in our drinking water—here"s how to reduce them
News reports of so-called forever chemicals in drinking water have left people worried about the safety of tap and bottled water. But recent research has shown there are ways to significantly reduce the levels of these harmful chemicals in our water......»»
Laser measurements help track space debris and observe water masses
What do the Earth's gravitational field and the trajectories of satellites and space debris have in common? The Earth's gravitational field influences the orbits of our companions in space, while the changes in the orbits in turn allow conclusions to.....»»
Researchers probe mechanical properties of silicon carbide
New research from the Ateneo de Manila University could pave the way for more durable versions of silicon carbide (SiC), a semiconductive ceramic material found mostly in space that has applications in everything from computer chips to spaceships......»»

Protecting northern water supplies from toxic metals in thawing permafrost
As the climate warms and Arctic permafrost thaws, some of the toxic elements locked away in it are starting to emerge and could contaminate the water supplies that many northern communities rely on......»»
Precise layering in catalysts offers an improved way for building sustainable chemicals
Motivated to turn greenhouse gases like carbon dioxide into high value chemicals like methanol, EPFL chemical engineers have developed a new method to make catalysts. Catalysts are major tools in the chemical industry and are largely made to make pet.....»»
Uranus" moon Miranda may have an ocean beneath its surface, study finds
A new study suggests Uranus' moon Miranda may harbor a water ocean beneath its surface, a finding that would challenge many assumptions about the moon's history and composition and could put it in the company of the few select worlds in our solar sys.....»»
Intensive fishing on the seabed increases the release of carbon, researchers find
Flatfish and shrimp are caught in the North Sea by using trawls that are dragged across the seabed. This releases carbon into the water and carbon dioxide (CO2) into the atmosphere, as shown by the latest research at the Helmholtz-Zentrum Hereon......»»
