Dartmouth-Hitchcock Norris Cotton Cancer Center A scientific breakthrough may give the field of radiation oncology new tools to increase the precision and safety of radiation treatment in cancer patients by helping doctors “see” the powerful beams of a linear accelerator as they enter or exit the body. We don't have X-ray vision. When we have an X-ray or mammogram, we cannot detect the radiation beam that passes through our bone or soft tissue, neither can our doctor. But what if we...

Mexico Observatory To Hunt For Gamma Rays In Known Universe
2013-08-22 07:35:15

April Flowers for redOrbit.com - Your Universe Online A new observatory has begun formal operations in Mexico. The High-Altitude Water Cherenkov (HAWC) Gamma Ray Observatory is designed to study the origins of very high-energy cosmic rays and observe the most energetic objects in the known universe. The HAWC uses a unique detection technique that is different from the classical astronomical design of mirrors, lenses, and antennae, making the extraordinary observatory a significant boost...

Cosmic Ray Origins Still A Mystery

April Flowers for redOrbit.com - Your Universe Online In August, physicists will gather to celebrate a century of research since the discovery of cosmic rays. It is widely accepted that cosmic rays are the nuclei of atoms, from the full array of naturally occurring elements that travel at near-light-speeds for millions of years before reaching Earth. What isn't known yet is where these cosmic rays originate. Alan Watson, emeritus professor of physics at the University of Leeds, provides...

Experimental verification of reversed Cerenkov radiation in left-handed metamaterial A team of physicists has directly observed a reverse shock wave of light in a specially tailored structure known as a left-handed metamaterial. Although it was first predicted over forty years ago, this is the first unambiguous experimental demonstration of the effect. The research is reported in Physical Review Letters and highlighted with a Viewpoint in the November 2 issue of Physics. Light moving in a...
