How can you tell if a green sea turtle will grow up to be male or female?

Researchers analyze the DNA and hormonal profile of the green turtles to understand their physiology, development and reproduction and ensure their survival

The earliest evidence of the production of edible olives was found

Researchers from the Hebrew University, the University of Haifa, the Technion, Aviv University, the Volcanic Institute and other research institutions from Israel and the world discovered the find at a site from about 6,500 years ago that sank into the sea. In this way, the discovery predates the ancient evidence that was known until now by about 4000 years.

Microscope image: The image, taken with a fluorescent microscope, shows a large amount of viruses (the small dots) attacking archaea (the large dots). For the purpose of photography, seawater was taken, filtered to get rid of large cells such as algae and most of the bacterial cells, and the DNA was stained with a fluorescent substance that binds to it.
