Remote high-voltage sensor unveiled

Ever since the first human placed a bare hand on an uninsulated electric line, people have refrained from personally testing energetic materials. Even meters made of metal can melt at high voltages.

Gamma-ray laser moves a step closer to reality

A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium.

Gamma rays reach beyond the limits of light

Researchers have discovered a highly efficient way to produce high energy photon beams. The obtained energy is a billion times higher than the energy of photons in visible light. These high-intensity gamma rays significantly ...

Supercomputers fire lasers to shoot gamma ray beam

Ever play with a magnifying lens as a kid? Imagine a lens as big as the Earth. Now focus sunlight down to a pencil tip. That still wouldn't be good enough for what some Texas scientists have in mind. They want to make light ...
