Time to think big: A call for a giant space telescope Posted: 22 Jun 2014 07:22 AM PDT In the nearly 25 years since the launch of the Hubble Space Telescope (HST), astronomers and the public alike have enjoyed ground-breaking views of the cosmos and the suite of scientific discoveries that followed. The successor to HST, the James Webb Telescope should launch in 2018 but will have a comparatively short lifetime.

Advanced CT scanners reduce patient radiation exposure, study finds Posted: 21 Jun 2014 06:31 PM PDT The use of advanced CT scanning equipment is helping to address the important concern of patient exposure to radiation. The study results provide information that will help in setting standards for radiation safety quality control in cardiovascular imaging.
