Why are there red anemones alongside purple, pink, and white anemones? Is this a random whim of nature, or perhaps colors that help the flowers evade hungry caterpillars? New research aims to solve the mystery

Colonies of ants began growing mushrooms when an asteroid hit Earth 66 million years ago. This damage caused mass extinction but also created ideal conditions for fungi to flourish. This is how an evolutionary partnership was created that became even closer 27 million years ago and continues to this day. Credit: Don Parsons

Ant farming began 66 million years ago following the asteroid that doomed the dinosaurs

Smithsonian Institution scientists compiled and analyzed an extensive genetic database, and found that some mushroom crops became completely dependent on ants 27 million years ago, a process created 65 million years ago by an event

Healthy bees, healthy planet: the effect of a balanced diet on honey bee colonies

New research has revealed that a balanced diet is essential to the health and performance of honey bees' tasks. The study shows that an unbalanced diet significantly delays the start of treatment for larvae, reduces the frequency of treatment

The 'pipe builder' snail was awarded the title of 'environmental engineer', in light of its contribution to the construction of rocky surfaces on the coastline and reducing their rate of weathering in an effective way. It came to the brink of extinction, but researchers from Ben Gurion University succeeded

Jellyfish of the "wandering thread" species of unprecedented sizes have been observed in recent days along the coast of Israel

After a summer without jellyfish, and the enormous size of the jellyfish in the winter swarms, we expect that the coming summer will be relatively abundant in jellyfish," said Dr. Dor Edelist, a marine biologist from the University of Haifa

Special for Passover: It turns out that slavery is not limited to humans, and various insects survive and multiply in nature thanks to the "slavery" of other species. So what do an army of small ants and Sparta have in common? What were cow barbers?
