The inexpensive device could improve health in the developing world and reduce mining risks

COLUMBIA, Mo. — The hand-held scanners, or tricorders, of the Star Trek movies and television series are one step closer to reality now that a University of Missouri engineering team has invented a compact source of X-rays and other forms of radiation. The radiation source, which is the size of a stick of gum, could be used to create inexpensive and portable X-ray scanners for use by doctors, as well as to fight terrorism and aid exploration on this planet and others.

“Currently, X-ray machines are huge and require tremendous amounts of electricity,” said Scott Kovaleski, associate professor of electrical and computer engineering at MU. “In approximately three years, we could have a prototype hand-held X-ray scanner using our invention. The cell-phone-sized device could improve medical services in remote and impoverished regions and reduce health care expenses everywhere.” (more…)

ARMONK, N.Y. – 17 Dec 2012: Today IBM unveiled the seventh annual “IBM 5 in 5” (#ibm5in5) – a list of innovations that have the potential to change the way people work, live and interact during the next five years.

The IBM 5 in 5 is based on market and societal trends as well as emerging technologies from IBM’s R&D labs around the world that can make these transformations possible. (more…)

For Ali Belkacem of Berkeley Lab’s Chemical Sciences Division, “What is chemistry?” is not a rhetorical question.

“Chemistry is inherently dynamical,” he answers. “That means, to make inroads in understanding – and ultimately control – we have to understand how atoms combine to form molecules; how electrons and nuclei couple; how molecules interact, react, and transform; how electrical charges flow; and how different forms of energy move within a molecule or across molecular boundaries.” The list ends with a final and most important question: “How do all these things behave in a correlated way, ‘dynamically’ in time and space, both at the electron and atomic levels?” (more…)
