UC Riverside Physicists Discover New Way to Produce Antimatter-containing Atom
Monday, July 11, 2011 - 20:08

Physicists at the University of California, Riverside report that they have discovered a new way to create positronium, an exotic and short-lived atom that could help answer what happened to antimatter in the universe and why nature favored matter over antimatter at the universe’s creation.

While you're up, print me a solar cell
Monday, July 11, 2011 - 10:33
New MIT-developed materials make it possible to produce photovoltaic cells on paper or fabric, nearly as simply as printing a document. The technique represents a major departure from the systems used until now to create most solar cells, which require exposing the substrates to potentially damaging conditions, either in the form of liquids or high temperatures. The new printing process uses vapors, not liquids, and temperatures less than 120 degrees Celsius. These “gentle” conditions make it possible to use ordinary untreated paper, cloth or plastic as the substrate on which the solar cells can be printed.

Aircraft systems in the environmental chamber
Sunday, July 10, 2011 - 21:17

The scientists hope to obtain fundamental insights into the effect of ambient temperature on the thermal behavior of aircraft systems. They will also study the interplay between components, materials and ambient temperature, particularly in the context of more electric architecture on aircraft. Three metal and fiber-composite fuselage sections of a Dassault business jet will be used to study the interplay of new electric systems and aircraft parts in different conditions.

'Citizen-seismologists' sought to host tiny earthquake sensors on their computers
Sunday, July 10, 2011 - 08:50

Six thousand tiny seismic sensors are seeking homes – or offices, or classrooms – where they can take up residence.  The matchbox-size sensors are part of a new phase of the Quake Catcher Network, a project that is building the densest networks of seismic sensors ever devoted to studying earthquakes.  All it takes to volunteer is a computer, an Internet connection, and a small patch of floor space.

Princeton researchers solve problem filling space -- without cubes
Saturday, July 9, 2011 - 14:27

Now, in findings published June 20 in the Proceedings of the National Academy Sciences, Princeton University chemist Salvatore Torquato and colleagues have solved a conundrum that has baffled mathematical minds since ancient times -- how to fill three-dimensional space with multi-sided objects other than cubes without having any gaps.
