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…

Detailing a disastrous autumn day in ancient Italy

The Plinian eruption of Mount Vesuvius around 4,000 years ago — 2,000 years before the one that buried the Roman city of Pompeii — left a remarkably intact glimpse into Early Bronze Age village life in the Campania region of Southern Italy. The villa…

Do humans think computers make fair decisions?

Today, machine learning helps determine the loan we qualify for, the job we get, and even who goes to jail. But when it comes to these potentially life-altering decisions, can computers make a fair call? Researchers have shown that with human supervisi…

Exposure to accents helps children learn words

• University of Freiburg study on vocabulary acquisition uses novel game-based design • Study results: Children of primary school age can benefit from long-term experience with multiple accents when learning words in unfamiliar accents from other child…
