The GOFLOW system, developed under the leadership of Tel Aviv University, allows for the identification of subtle flow movements in the ocean and may improve models of the climate crisis, storms, and heat and gas exchange between the sea and the atmosphere.

A new discovery changes what we thought about the ghost wheel in the Golan Heights

As a result of geodynamic shifts in the area of ​​Rojam al-Khiri - the ground in the area rotated, so it is unlikely that the ancient site was used as an observatory
Magnesium oxide, the first component that crystallized in the process of creating a planet slightly larger than Earth. The image was prepared using DALEE and should not be considered a scientific image

Firecrackers and thunder: Lightning storms accelerate the rate of ice melting in the North Pole

An international study with the participation of Tel Aviv University states: Global warming leads to lightning storms in the North Pole, which further accelerate the process of melting the ice - in a cycle of repeated feeding
