Harvard University scientists say the Sun may once have had a binary companion with a similar mass. If the theory is confirmed, the presence of an ancient companion star increases the likelihood that the Oort cloud formed as it is observed

Scientists have succeeded in increasing the efficiency of the photosynthesis process in algae by an order of magnitude

A study by researchers at Ben Gurion University shows that increasing the photosynthetic efficiency 3 to 10 times at light intensities similar to the intensity of sunlight, which is used in conventional growing facilities, is possible

Water war or water peace?

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 completed the
