When water is cooled below zero degrees, it usually crystallizes directly into ice. Ove Andersson, a physicist at Umeå University, has now managed to produce sluggishly flowing water at 130 degree below zero under high pressure -- 10,000 times higher than normal pressure. It is possible that this sluggishly fluid and cold water exists on other heavenly bodies.

A new alloy with unique properties can convert heat directly into electricity, according to researchers at the University of Minnesota. The alloy, a multiferroic composite of nickel, cobalt, manganese and tin, can be either non-magnetic and highly magnetic, depending on its temperature.

A discovery by researchers working at the Spallation Neutron Source upends long held assumptions about the microscopic behavior of materials in an equilibrium condition. The findings could influence further research in advanced materials, communication and optical systems, and thermoelectric materials that use differences in temperature to produce electricity.

Cheap, much lighter than before and allowing for continuous operation -- what traditional batteries can not offer -- direct formic acid fuel cells can revolutionize the portable electronics market. A new catalyst developed at the Institute of Physical Chemistry of the Polish Academy of Sciences will enable a widespread use of fuel cells, researchers say.

With the Monday morning announcement of a new solar energy plant, New Jersey may become a solar power hub in the near future. The New York-based McGraw-Hill Companies and NJR Clean Energy Ventures announced today that they plan to build the largest privately-owned solar plant in the Western Hemisphere on McGraw-Hill’s East Windsor, New Jersey campus.

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 a superfluid that provides no resistance to electrons as they flow through it.

It seems perfectly natural to expect that two motorists who depart from the same location and follow the same directions will end up at the same destination. But according to a Johns Hopkins University mathematical physicist, this is not true when the "directions" are provided by a turbulent fluid flow, such as you find in a churning river or stream.
