SUNRISE offers new insight on sun's atmosphere

Posted: 27 Sep 2013 03:33 PM PDT

Three months after the flight of the solar observatory Sunrise -- carried aloft by a NASA scientific balloon in early June 2013 -- scientists have presented unique insights into a layer on the sun called the chromosphere. Sunrise provided the highest-resolution images to date in ultraviolet light of this thin corrugated layer, which lies between the sun's visible surface and the sun's outer atmosphere, the corona.

Accelerator on a chip: Technology could spawn new generations of smaller, less expensive devices for science, medicine

Posted: 27 Sep 2013 10:47 AM PDT

In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice.

3-D models of electrical streamers

Scientists have developed an accurate 3-D model of streamer propagation that qualitatively and quantitatively describes the streamer development, an advance that may impact applications such as medical imaging, aerospace engineering, power transmission, atmospheric sensing, natural sciences, sensing technologies and large-scale industry.

Bright, laser-based lighting devices
