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

Researchers from Ben Gurion University have developed an artificial intelligence model that predicts the embryo's chances of rooting, based on information from fetal siblings from the same treatment cycle
Researchers at the University of Queensland have found that humans can understand the emotional state of chickens from the sounds of their clucking. This ability, which is not affected by previous experience with chickens, has significant implications for improving poultry welfare and can assist in the development of artificial intelligence-based surveillance systems.

Corals from the Red Sea have invaded Israel's Mediterranean coast

  • No comments
Until now, the low temperatures of the Mediterranean water in winter have been a barrier to the arrival of tropical corals. The establishment of the Dendronaphtia we found indicates that at least last winter, the waters of the Mediterranean Sea were warmer than before
Histological sections of the leg muscles without injury (left) and five days after it (center, right) in a control mouse and a transgenic mouse. It can be seen that the area of ​​the muscle fibers that develop after the injury is smaller in the transgenic mouse, which indicates a disturbance in the differentiation of the stem cells into muscle cells

overcome the damage

Researchers have discovered that two epigenetic events (removing and adding methyl from DNA) lead to the differentiation of stem cells into muscle cells and thus to the regeneration and healing of muscles after their injury

"Artificial intelligence has the potential to improve our lives in a variety of ways"

  • One response
Dr. Aya Sofer, director of IBM's research laboratory in Israel, was a guest at the high-tech Silicon Club managers' forum: "Besides the many advantages, there are of course also challenges that are not easy, such as a built-in bias in models or data, or the creation of fake news and its use to bias public opinion. To combat these, we must adopt ethical information standards for the use of artificial intelligence - and educate consumers to use it critically."

A mystery in Jerusalem: What were the mysterious canal facilities from the days of Kings Jehoash and Amaziah that were uncovered in the City of David National Park used for?

  • One response
The canal facilities, the likes of which have not yet been discovered in Israel, were in use about 2,800 years ago - during the time of the First Temple; According to the researchers from the Antiquities Authority and Tel Aviv University, "it is possible that the canals were used to soak some product. The central location of the canal facilities shows that the product produced in them was associated with a palace or a temple.
