The dance of hot nanoparticles
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 ...
Researchers create rollerball-pen ink to draw circuits
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 ...
Water in Earth's mantle may be associated with subduction
A team of scientists from Oregon State University has created the first global three-dimensional map of electrical conductivity in the Earth's mantle and their model suggests that that enhanced conductivity ...
Study Finds that Styrofoam Increases Biodiesel Power Output
A sticky business -- how cancer cells become more 'gloopy' as they die
The viscosity, or 'gloopiness', of different parts of cancer cells increases dramatically when they are blasted with light-activated cancer drugs, according to new images that provide fundamental insights into how cancer ...
Increasing oil flow in the Keystone pipeline with electric fields
Researchers have shown that a strong electric field applied to a section of the Keystone pipeline can smooth oil flow and yield significant pump energy savings.
Cilia use different motors for different tasks
Cilia—short, hair-like fibers—are widely present in nature. Single-celled paramecia use one set of cilia for locomotion and another set to sweep nutrients into their oral grooves. Researchers at Brown ...
Why cement tends to thicken
Researchers at the ETH Zurich have unraveled the microscopic mechanism behind shear thickening: the increase in viscosity with speed observed for dense particle suspensions under flow. The study has a direct ...
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 ...
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.
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.
