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

New 'workout pill' can cause fitness benefits without exercise

  • No comments
Researchers report new compounds that appear to be able to mimic the physical drive of exercise—at least in rodent cells. This discovery could lead to a new way to treat muscular dystrophy and other medical conditions in humans, including heart failure and neurodegenerative diseases

Sexual frustration leads to stress in fruit flies

The research insights of Yulia Rivkin from the Faculty of Life Sciences in Bar-Ilan open up an opportunity for in-depth research into the effect of stress on the nervous system
The pituitary gland of the zebrafish. The variety of cell types are marked in different colors: in purple - phytocytes, in red and green - two types of hormone-producing cells

Where does the fish secrete from: back to the origins of the pituitary gland

Weizmann Institute scientists are challenging a 200-year-old doctrine about the formation of the gland from the secretion of hormones. Their findings may lead to new approaches in the treatment of various medical problems

In theory, a male skin cell can be turned into an egg and a female skin cell into a sperm cell. There is also the possibility of a child genetically connected to several parents, or only to one parent

Etrog in danger: will it be impossible to grow etrog in Israel in the future?

The etrog is currently at risk due to the rise in global temperatures as part of the climate crisis, and it is possible that the day will come when we will no longer be able to grow etrogs in Israel - for the first time in 2,500 years

According to Dr. Motty Charter, the fact that two amateur observers are the ones who identified the raccoon, an endangered species, through watching the Charter Group's Birds Online YouTube channel, highlights the enormous importance of citizen science in protecting wildlife.

Phoenix of the sea

The animal that breaks the laws of nature: a new Israeli study reveals that the colonies of the flower botryll, a unique marine creature, age in their entirety - and then return to being young again. The phenomenon received the term "Orshina rhythm" - the Talmudic name of the mythological phoenix

The researcher who fell in love with the coral reefs - and became a fighter for their preservation

A Lifetime Achievement Award was awarded as part of the 51st Annual Science and Environment Conference to Prof. Yossi Levia. In a celebratory interview, he talks about his love for the profession, the corals and the researchers who grew up in his laboratory - and also warns: "Ktsa'a could cause an unprecedented ecological disaster on our reefs and those of our neighbors to the south."

Protection from the plant

A new Israeli study reveals that the desert gorse, a common plant in the country, releases a pungency that prevents many animals from eating it - but gives the bulbul birds a "medicine" that helps them digest its fruits. And: how is all this related to cancer prevention?

The protein that helps the enemy

A certain essential protein increases the expression of another protein in cancer cells in the uterus - and this transforms its skin, encourages them to divide and thus contributes to the spread of the tumor

The unique finding provides insights into understanding the species' resistance to environmental changes that took place during its existence in Ethiopia and emphasizes the urgency of the need for a conservation policy of its ecological environment in light of climate change in the near future and its being in danger of extinction

We were slaves to the ant and the butterfly

Special for Passover: It turns out that slavery is not limited to humans, and various insects survive and multiply in nature thanks to the "slavery" of other species. So what do an army of small ants and Sparta have in common? What were the ladybugs telling their psychologist? And who survives thanks to an army of drugged security guards?

A worldwide breakthrough states: plants make sounds

Each plant and each type of distress has a characteristic, recognizable sound. The sounds of plants sound like clicks, like popcorn, at a volume similar to human speech but at frequencies above the human hearing range, and they may be picked up by various animals, such as bats, mice and insects
