Less bird diversity in city forests

A new study shows that cities negatively affect the diversity of birds. There are significantly fewer bird species in urban forests compared with forests in the countryside — even if the forest areas are of the same quality.

New light for shaping electron beams

A new technique that combines electron microscopy and laser technology enables programmable, arbitrary shaping of electron beams. It can potentially be used for optimizing electron optics and for adaptive electron microscopy, maximizing sensitivity whi…

Elastic nozzles could create more stable liquid jets

Until now, little attention has been paid to the flow of liquid through deformable elastic nozzles. New research introduces the concept of passively-deforming nozzles, and shows that softer nozzle materials can produce more stable jets across a wide ra…
