Physicists demonstrate first time reversal of water waves
Custodian of world's longest running experiment dies
The science professor who oversaw the world's longest running laboratory test—the Pitch Drop Experiment—has died after more than half a century on its watch, his university said Monday.
New model of cosmic stickiness favors 'Big Rip' demise of universe
The universe can be a very sticky place, but just how sticky is a matter of debate.
Images capture split personality of dense suspensions
Stir lots of small particles into water, and the resulting thick mixture appears highly viscous. When this dense suspension slips through a nozzle and forms a droplet, however, its behavior momentarily reveals ...
The perfect liquid -- now even more perfect
Ultra hot quark-gluon-plasma, generated by heavy-ion collisions in particle accelerators, is supposed to be the "most perfect fluid" in the world. Previous theories imposed a limit on how "liquid" fluids can ...
Study Finds that Styrofoam Increases Biodiesel Power Output
Scientists capture pitch drop on camera for first time (w/ Video)
The Pitch Drop experiment set up in 1944 at Trinity College Dublin's School of Physics is one of the world's oldest continuously running experiments.
The dance of hot nanoparticles
Experimental evidence adds to the likelihood of the existence of supersolids, an exotic phase of matter
Supersolids and superfluids rank among the most exotic of quantum mechanical phenomena. Superfluids can flow without any viscosity, and experience no friction as they flow along the walls of a container, because ...
Physicists hit on mathematical description of superfluid dynamics
(PhysOrg.com) -- It has been 100 years since the discovery of superconductivity, a state achieved when mercury was cooled, with the help of liquid helium, to nearly the coldest temperature achievable to form ...
Mixing processes could increase the impact of biofuel spills on aquatic environments
Ethanol, a component of biofuel made from plants such as corn, is blended with gas in many parts of the country, but has significantly different fluid properties than pure gasoline. A group of researchers from the University ...
Supervolcanic ash can turn to lava miles from eruption, scientists find
Supervolcanoes, such as the one sitting dormant under Yellowstone National Park, are capable of producing eruptions thousands of times more powerful than normal volcanic eruptions. While they only happen ...
Study suggests viscous materials do not follow standard laws below a sub-melting point threshold
So-called glass-formers are a class of highly viscous liquid materials that have the consistency of honey and turn into brittle glass once cooled to sufficiently low temperatures. Zhen Chen and his colleagues from Arizona ...
Cell viscosity research improves our knowledge of cancer cells
EU-funded researchers from Germany and Poland have made some groundbreaking discoveries about cell cytoplasm viscosity, which could further our knowledge of the cytoplasm of cancer cells.
