How enzymes locally block cell wall repair, allowing cells to fuse in an irreversible manner
المصدر: Phys.org - latest science and technology news stories · نُشر
The fusion of two cells is a decisive event in the sexual reproduction of many organisms. In fungi, cells must not only bring their membranes together and merge them, but also locally open their protective cell wall.

Brain cells meant to protect us may be fueling cognitive decline
Scientists have uncovered a surprising cause of age-related cognitive decline involving brain cells previously thought to be entirely beneficial. As these cells become dysfunctional, they can produce abnormal amounts of myelin, disrupting nerve fibers and potentially contributing
