All Stories by Peter Weiss
- Physics
Old data yield new signs of extra force
Several experimental findings that conflict with predictions of the prevailing standard model of particle physics suggest that nature may include another force beyond the four known ones.
- Physics
Catch a Wave
Detection of gravitational waves predicted by Einstein's 1916 general theory of relativity may finally occur, thanks to a new generation of laser-based observatories.
- Materials Science
Tiny gems on steps find future in films
The discovery of diamond-crystal seeds on steps in silicon may lead to long-sought, large wafers of pure, single-crystal diamond for electronics and other uses.
- Physics
Time’s arrow may make U-turns in universe
Time may run backwards for isolated chunks of matter in our universe and that reversed state could be probed gently from the forward-going realm without disturbing the time arrow.
- Physics
Matter waves: Be fruitful and multiply
For the first time, physicists induced atoms to amplify a selected matter wave in a manner analogous to a cascade of photons amplifying the characteristic electromagnetic wave of an optical laser.
