Physics
We summarize the week's scientific breakthroughs every Thursday.
- 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.
- Physics
Electrical superball pulls itself together
A strong electric field can drive tiny particles of a superconductor to bind themselves together into a remarkably sturdy ball.
- 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
Computers Crunch Quantum Collisions
Physicists have mathematically described what happens when an electron collides with a hydrogen atom, accomplishing a longstanding goal.
- 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.
- Materials Science
Small-scale glues stick to surfaces
Tailored molecular glues can connect together tiny particles for nanotechnology applications.
- Materials Science
Impurity clouds from all sides now
For the first time, scientists have obtained detailed, three-dimensional images of line defects in steel.
