Meet our guest, glowing a phosphorescent shade of green: a new jellyfish which has arrived from Japan and was observed for the first time in the Mediterranean Sea during a routine survey conducted by Dr. Gur Mizrahi, a researcher from the laboratory of Dr. Dan Tchernov in the Leon H. Charney School of Marine Sciences: the Aequorea macrodactyla (Cnidaria Hydrozoa), a species of medusa spotted repeatedly in the Sea of Japan. The good news: This medusa is not dangerous to humans. The bad news: its arrival heralds that much more dangerous visitors can get here as well. “This is a particularly unique jellyfish, as it contains a fluorescent green-colored protein the role of which, despite many theories, is still not clear to science. Despite its small body – just a few centimeters in length – it devours plankton and small crustaceans; but we can stay calm – as it’s not dangerous to humans,” said Dr. Mizrahi.

Strained relationships between sisters, one of whom has an eating disorder, can cause the healthy sister to develop high emotional distress and depression

תמונה תומכת תוכןHealthy Sisters of women with eating disorders show a higher level of depressive symptoms than women whose sister is not suffering from an eating disorder, according to a new study. The study also found that the relationship between the sisters, one of whom has an eating disorder, is worse than that between sisters neither of whom suffers from an eating disorder. “The worse the relationship between the two sisters, the greater the level of psychological distress becomes for the healthy one, which in turn places her at risk of developing an eating disorder of her own,” said Prof. Yael Letzer from the Faculty of Social Welfare and Health Sciences.
