The Surprising Players of the Immune System That May Cultivate Bacteria

The new findings may allow the development of new treatments for infections, such as tuberculosis, salmonella and Shigella, and for life-threatening reactions of the immune system

The new findings of researchers at the Weizmann Institute may advance the cultured meat industry
In the growth plate in the tibia of a mouse (left), the cartilage cells grow gradually, from the smallest, at the edge of the bone (in blue), to the largest, closer to the center (in red). In a mouse with a mutation in the Gdf5 gene (right) the gradual growth goes wrong

How we grow: the XNUMXD version

The institute's scientists developed an innovative method for examining hundreds of thousands of cartilage cells in XNUMXD - and with it revealed new information about bone growth
Similar organization of the FIKL cells discovered in the study (left) and pancreatic beta cells (right): the RNA molecules for insulin production (pink-oval) are located closer to the center of the cell, while the insulin molecules themselves (green) accumulate near the cell wall and readiness for discharge

catch the disease

The institute's scientists located a molecule that irreversibly attaches to a protein that contributes to the development of malignant tumors. Their findings may lead to the creation of a new cancer drug

A body odor molecule common in babies reduces aggression in men and increases it in women

These findings are among the first to directly link human behavior, brain mechanism and smell molecule

The distribution of attention of blood vessels

The scientists of the institute discovered that the blood vessels "separate" between cell division and branching in new directions. The findings imply that chemotherapy treatments may encourage the growth of blood vessels in the tumor

Directing a view to the edge of the universe: the Weizmann Institute joins the partnership with the giant "Magellan" telescope in Chile

The joining will open up new possibilities for the institute's scientists in space research and will allow them to observe billions of light-years away with a resolution 10 times higher than that of the Hubble Space Telescope.
