Research: Childhood experiences determine the boldness of bats in the wild

A study by Tel Aviv University found that the environment in which young bats grow up affects their boldness, flight distances, and foraging patterns in adulthood.

Greenland shark retains sight for centuries. Possibly with DNA repair

A study in Nature Communications found adaptations for low-light vision and hints at maintenance mechanisms that prevent retinal degeneration in extreme old age. However, despite the evolutionary and environmental distance, it may be possible to learn something about the preservation of vision in humans.

Living in the moment: Egyptian fruit bat reveals astonishing navigation and memory skills

Prof. Yossi Yuval explains how the fruit bat common in Israel combines night vision, sonar, and spatial memory – and also contributes to seed dispersal and tree pollination.

The Cat in Israel's Sources 1: Going Back in Time

From the prehistoric cat to the domestic cat – this is how the nocturnal creature became a constant companion of man, a sacred animal in Egypt, identified with demons and symbols in the Passover Haggadah, and mysterious even in the eyes of the Talmudic sages.

The divergent adaptation of cuckoos

Cuckoos develop eggs and chicks that resemble those of their hosts, to avoid detection. When they have more than one host, this can lead to the creation of new species of cuckoos – especially if they are “violent”.

The complex language of birds

Studies from Israel and abroad have found that birds do not chirp only for courtship purposes, and that they have a complex language that affects their choice of who to communicate with and how - even during migration
