NPL unveils new equipment to make cancer treatment safer

A new piece of medical technology unveiled at the National Physical Laboratory (NPL) today will help improve the success rates of radiotherapy cancer treatments. The new clinical electron linear accelerator (linac) will help ensure patients are treated with accurate doses of radiation.

Researchers break world record for drive systems

In future it can be expected that the drill used in material processing will become even faster and the compressor used for vehicles and airplanes even more compact. In order to drive these rotary applications directly, efficiently and in a controlled fashion, there must be electrical drive systems with the appropriate rpm and engine power. Up to now, industrially-deployed motors have normally...

Surface plasmon resonances of metal nanoparticles in array can have narrower spectral widths

Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated experimentally and theoretically that the surface plasmon resonances of metal nanoparticles in a periodic array can have considerably narrower spectral widths than those of isolated metal nanoparticles. Further, as the optical fields are significantly more intense in a periodic array, the method could...

First 'exoplanets' photographed from Earth

Astronomers have taken the first pictures of planets orbiting a distant star using telescopes on the Hawaiian island of Mauna Kea. Three giant planets were snapped around a star known as HR 8799 in the constellation of Pegasus, 130 light years from Earth. Until now, images of "exoplanets" beyond our solar system have only been taken from space, or inferred indirectly. "We've been trying to image...
