Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how ...

It is widely assumed that diffraction places a limit on the smallest features that can be produced by light-based fabrication techniques, such as photolithography. This limit is typically about ...

Several approaches are capable of beating the classical 'diffraction limit'. In the optical domain, not only are superlenses a promising choice: concepts such as super-oscillations could provide ...

Journaling for just a few minutes every day can help turn it into a stress-relieving, sustainable habit. It may help to write at the same time each day or use prompts for fresh ideas. One of your best ...
