Observing the positronium beam as a quantum matter wave for the first time

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

Tightening the focus of subcellular snapshots: Combined approach yields better cell slices for cryoET imaging

Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons ...
