Seven years ago Northwestern University physicist Adilson E. Motter conjectured that the expansion of the universe at the time of the big bang was highly chaotic. Now he and a colleague have proven it using rigorous mathematical arguments. The study, published by the journal Communications in Mathematical Physics, reports not only that chaos is absolute but also the mathematical tools that can be used to detect it. When applied to the most accepted model for the evolution of the universe,...

PTB physicists want to improve tumour therapy by heat treatment in cooperation with biomedical physicians from Jena Those who have to fight a powerful enemy must look for allies. This is why physicists from different scientific fields have decided to cooperate with biomedical physicians in order to place the fight against cancer through heat treatment by means of magnetic nanoparticles on a solid, scientific basis. It is the objective of the cooperation to improve the success of the therapy....

Oil and natural gas companies rely upon geological core analyses to help them understand and evaluate oil and gas reserves. A rock sample can reveal myriad details about a geological structure's formation, content, and history. Conductivity, a material's ability to carry an electrical current, is one of the most useful measurements of core samples. The conductivity of a geological formation depends on the direction of measurement, so it's considered "anisotropic." "Anisotropy is usually the...

While those wonderful light sabers in the Star Wars films remain the figment of George Lucas' fertile imagination, light mills "“ rotary motors driven by light "“ that can power objects thousands of times greater in size are now fact. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory and the University of California (UC) Berkeley have created the first nano-sized light mill motor whose rotational speed and direction can be controlled by...

'Most condensed form of energy storage outside of nuclear energy' The world's biggest Roman candle has got nothing on this. Using super-high pressures similar to those found deep in the Earth or on a giant planet, Washington State University researchers have created a compact, never-before-seen material capable of storing vast amounts of energy. "If you think about it, it is the most condensed form of energy storage outside of nuclear energy," says Choong-Shik Yoo, a WSU chemistry professor...

VALHALLA, N.Y., June 2 /PRNewswire-USNewswire/ -- The warm weather usually means lots of summer fun and outdoor activities. Unfortunately, the combination of high heat and high humidity often become very dangerous. Temperatures over the next few days are expected to be in the upper 90's with a heat index of over 100 and that can often cause health problems especially in older adults and infants. High temperature and increased humidity can be very dangerous for both of these groups as...

CHARLESTON, W.Va., June 15 /PRNewswire-USNewswire/ -- The Federation for American Coal, Energy and Security (FACES of Coal) released a video on its website, www.facesofcoal.org, today explaining in easy-to-understand terms and examples why the use of conductivity is an ill-advised and inappropriate measure for water quality impairment. The U.S. Environmental Protection Agency (EPA) recently issued guidance on water quality requirements for coal mines in six Appalachian states. This...

While attempting to solve one mystery about iron oxide-based nanoparticles, a research team working at the National Institute of Standards and Technology (NIST) stumbled upon another one. But once its implications are understood, their discovery* may give nanotechnologists a new and useful tool. The nanoparticles in question are spheres of magnetite so tiny that a few thousand of them lined up would stretch a hair's width, and they have potential uses both as the basis of better data storage...
