Researchers discover that hairpins can make a polymer spaghetti fluid
Researchers from FOM Institute AMOLF and the German Forschungzentrum Jülich have discovered why polymers in a solution become fluid if the solution is stirred. They discovered that the polymer structure ...
Solar dimming caused by air pollution increases river-flows
A study published in Nature Geoscience shows that air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere.
'Smart' bandage emits phosphorescent glow for healing below
Inspired by a desire to help wounded soldiers, an international, multidisciplinary team of researchers led by Assistant Professor Conor L. Evans at the Wellman Center for Photomedicine of Massachusetts General ...
Elk nose into Grand Canyon water stations
Thirsty hikers have to wait. The elk are first in line.
Adding uncertainty to improve mathematical models
Mathematicians from Brown University have introduced a new element of uncertainty into an equation used to describe the behavior of fluid flows. While being as certain as possible is generally the stock and ...
Star Trekish, rafting scientists make bold discovery on Fraser River
A Simon Fraser University-led research team studying river flow in bedrock canyons for the first time has discovered that previous conceptions of flow and incision in bedrock-rivers are wrong.
Bird brains more precise than humans'
(Phys.org) —Birds have been found to display superior judgement of their body width compared to humans, in research to help design autonomous aircraft navigation systems.
How a change in slope affects lava flows
As soon as lava flows from a volcano, exposure to air and wind causes it to start to cool and harden. Rather than hardening evenly, the energy exchange tends to take place primarily at the surface. The cooling ...
Enhancing the mixing of viscous fluids for chemical reactions
Devices that manipulate very small volumes of fluids are applied in diverse fields, including printer technology, DNA processing and cooling systems for electronics. For some processes involving fluids, such ...
Lava from Hawaii volcano continues slow flow
The hot lava flowing from Hawaii's active volcano has quickened its creep toward a sparsely populated neighborhood.
Lava flowing toward homes on Hawaii's Big Island
Residents in a rural, isolated region of Hawaii's Big Island still reeling from a recent tropical storm turned their attention to a potential new disaster Thursday as scientists warned that a lava flow from ...
Tavurvur in Papua New Guinea is the latest volcano to watch
Last week, the eyes of volcanologists – and presumably a few nervous pilots – were fixed on Iceland. But unexpectedly, the volcanic eruption that made headlines happened on the other side of the world, ...
New imaging technique shows how cocaine shuts down blood flow in mouse brains
A new method for measuring and imaging how quickly blood flows in the brain could help doctors and researchers better understand how drug abuse affects the brain, which may aid in improving brain-cancer surgery ...
Microtomography of multiphase flows in porous media
Multiphase flow in porous media occurs in many practical situations including carbon dioxide capture and storage, enhanced oil recovery, remediation of polluted ground, and soil science.
