Forscherin entschlüsselt das Vokabular des Zebrafinken

THE GUARDIAN

Dr. Julie Elie hat nach über zehn Jahren Feldarbeit 11 Kernlaute des Zebrafinken identifiziert und ihre Bedeutungen kartiert. Die Vögel verwechseln Rufe mit ähnlicher Bedeutung häufiger als ähnlich klingende — ein Hinweis, dass sie nicht nur auf Tñne, sondern auch auf Inhalt reagieren. Maschinelles Lernen half, Tausende Aufnahmen zu strukturieren und auszuwerten.

More children's hospitals across the US are adding full-time facility dogs — specially trained working dogs embedded in care teams. Research shows they lower pain, blood pressure, and cortisol levels in young patients. One nonprofit, Canine Assistants in Georgia, has placed over 80 dogs nationally, and the annual Facility Dog Summit nearly doubled in attendance from 2024 to 2025.

The Blue-Fronted Lorikeet — a small, lime-green parrot found only on the Indonesian island of Buru — has been rediscovered after more than a decade. A 14-day expedition in April reached the unexplored highlands of Mount Kapalatmada and spotted at least nine individuals, capturing the first known sound recordings of the species' calls.

Philadelphia City Council voted to ban horse-drawn carriages — both commercial and noncommercial — effective June 26, with fines of $1,000 per day for violations. Chicago banned the practice in 2020, San Antonio in 2024. New York City's new mayor, Zohran Mamdani, has also voiced support for removing carriages from Central Park.
