Handheld Tools Perform Tasks Based on User’s Motions

What if handheld tools knew what needs to be done and were even able to guide and help inexperienced users to complete jobs that require skill? Researchers at the University of Bristol (UK) have developed a novel concept in robotics: intelligent handheld robots.

Compact Light Source Improves CT Scans

A new study shows that the recently developed Compact Light Source (CLS) – a commercial X-ray source with roots in research and development efforts at the Department of Energy’s SLAC National Accelerator Laboratory – enables computer tomography scans that reveal more detail than routine scans performed at hospitals today. The new technology could soon be used in preclinical studies and help researchers better understand cancer and other diseases.

"TREASORES" Project Moves Towards "Printed" Organic Solar Cells, LEDs

Flexible optoelectronic devices that can be produced roll-to-roll – much like newspapers are printed – are a highly promising path to cheaper devices such as solar cells and LED lighting panels. Scientists from "TREASORES" project recently demonstrated prototype flexible solar cell modules, as well as novel silver-based transparent electrodes, that outperform currently used materials.

Generating Broadband Terahertz Radiation from Microplasma in Air

Researchers at the University of Rochester’s Institute of Optics have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation. Fabrizio Buccheri and Xi-Cheng Zhang recently demonstrated that an approach for generating terahertz waves using intense laser pulses in air – first pioneered in 1993 – can be done with much lower power lasers, a major challenge until now.A microplasma is created by focusing intense laser pulses in air. Besides visible light, the microplasma emits electromagnetic pulses at terahertz frequencies that can be used to detect complex molecules, such as explosives and drugs. (Photo: J.
