A worldwide breakthrough states: plants make sounds

Each plant and each type of distress has a characteristic, recognizable sound. The sounds of plants sound like clicks, like popcorn, at a volume similar to human speech but at frequencies above the human hearing range, and they may be picked up by various animals, such as bats, mice and insects

Dolphin, do you like fishing?

For several decades dolphins and fishermen have been hunting together on the beaches of southern Brazil. A new international study reveals how this cooperation contributes to the marine mammals' chances of survival and what we must do so that it does not disappear from the world

The heavy price that corals may pay due to climate change

  • No comments
Global warming affects life in the sea in many ways when it causes a decrease in dissolved oxygen in the ocean water on the one hand, and on the other hand, an increase in the metabolism of marine animals, which further increases their need for oxygen

The chameleon in disguise

The decoration of chameleons is not limited to their outer part - and the bones of many of them glow through their skin under ultraviolet light. This is how the chameleons never stop surprising with original costumes that can be an inspiration for our most colorful holiday

Life at stake: the weight of wild mammals dwarfs that of farm animals

The biomass of cows, pigs, sheep and other farm animals is currently 30 times greater than that of all elephants, elk and other wild land mammals combined

SCIENCE: The Near East is the origin of the oldest vine in the world

  • No comments
An international study published in the journal Science, in which researchers from several institutions in Israel also participated, sheds light on the origin of the grapevine for food and wine, and proves that the grapevine was simultaneously domesticated in the Levant and secondarily in the South Caucasus * The research will also help agricultural crops deal with the current climate crisis

Cold feet: the secret of walking on the ice of polar bears

Special for Polar Bear Day: American researchers have discovered the reason why polar bears walk without difficulty on ice and snow surfaces that would cause each and every one of us to slip - microscopic bumps that line their furry feet

The mechanism of light reflection in the eyes of young crabs was discovered

  • One response
An international research group led by scientists from Ben-Gurion University of the Negev discovered among a species of crabs a mechanism that produces a unique eye shine that reflects light in a color adapted to the color of the water in their natural environment and thus enables camouflage in different habitats. The research findings were published in the journal Science

Genes conferring resistance to bread wheat were discovered

  • No comments
A new international study conducted at the University of Haifa and the University of California (Davis) found for the first time genes that confer resistance to drought conditions in bread wheat. "The discovery is of great importance that will allow the cultivation of wheat in extensive climatic conditions," said Dr. Gilad Gabai, the lead author of the article published in the prestigious journal Nature Communications
