Tracking the dynamics of biomolecules with optofluidic antennas

In order to better understand fundamental processes in life science at the molecular level, the precise observation of single molecule dynamics is of utmost interest. However, current techniques based on fluorescence measurements ...

Observing macroscopic quantum effects in the dark

Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment proposed by theoretical physicists in a recent paper published in Physical Review Letters. An object evolving in a potential ...

Why does matter exist? Roundness of electrons may hold clues

In the first moments of our universe, countless numbers of protons, neutrons and electrons formed alongside their antimatter counterparts. As the universe expanded and cooled, almost all these matter and antimatter particles ...

Investigating electrons with a traditional scanning microscope

Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have designed a framework that allows scientists to observe interactions between light and electrons using a traditional scanning electron microscope. ...
