Gravity causes homogeneity of the universe

Gravity can accelerate the homogenization of space-time as the universe evolves. This insight is based on theoretical studies of the physicist David Fajman of the University of Vienna. The mathematical methods developed within ...

It's time we stopped human evolution, geneticist claims

Measles cases in the US have hit a 25-year high, with 78 new infections in the past week alone. In a sign of the times, a cruise ship with hundreds of Scientologists on board was quarantined in St Lucia after one passenger ...

Quantum simulation more stable than expected

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers. These problems are otherwise challenging for conventional computers. This brings such digital quantum simulation ...

Physicists reverse time using quantum computer

Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated ...

The pho­to­elec­tric ef­fect in stereo

In the photoelectric effect, a photon ejects an electron from a material. Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their results they can deduce ...
