Three researchers shared the Nobel Prize in Physics for advances in laser physics. The winners include a woman for the first time in 55 years.
‘Quantum Atmospheres’ May Reveal Secrets of Matter
A new theory proposes that the quantum properties of an object extend into an “atmosphere” that surrounds the material.
A Short History of the Missing Universe
Astronomers have known where the universe’s missing matter has been hiding for the past 20 years. So why did it take so long to find it?
A New Test for the Leading Big Bang Theory
