A new angle in the theory that explains the variety of tree species in the rain forest

  • No comments
"Until now, the theory explained the existence of a variety of species of trees in the rain forest only through the existence of the natural enemies of each species, mainly insects and fungi. The current study puts emphasis for the first time on the conditions that will allow these enemies to thrive," explains the lead researcher

The thirsty fruits of the Mediterranean basin

Grapes, wheat and corn: according to a new study, popular agricultural crops in the Mediterranean countries will need more irrigation in the near future - and this when the water sources in the region are only dwindling. How are Israeli farmers preparing for this? And why, despite what appears on our water bill, does water have no price?

Is the answer to understanding the climate crisis found in the depths of the Dead Sea?

A group of Israeli geologists has been investigating the deep layers of the Dead Sea floor for the last decade, with the aim of revealing the climatic history of the area and producing local and global climatic forecasts. The conclusions of the studies may illuminate climate research in a new light

A new method The age of the sand in the world's largest deserts

In studies conducted using a new model, based on data measured in sands from the Kalahari Desert in Africa and the Simpson Desert in Australia, researchers were able to find that the ancient sands date back to the present - a few million years at least, and that the new method they created can be used for the purpose of dating ancient deserts and learning the migration patterns of sands and their creation

Building dams on rivers for the purpose of generating electricity or distributing water has always caused discussions and friction because of the need for "green" energy and the transportation of water, versus the desire to preserve the environment and nature. Ethiopia has completed the dam on the Blue Nile and the tension between it and Egypt is increasing
