Researchers studied how certain cells protect the brain in zebrafish. They found that young zebrafish can keep their brain shield working even without certain cells, but older ones have problems with brain protection, leading to leaks in big blood vessels. This suggests different roles for these cells as zebrafish grow.

Cohesin is a protein complex that helps keep chromosomes together and working properly. In yeast, scientists found that when TORC1, a protein related to cell growth, is less active, it helps cohesin work better, especially when the cohesin has trouble. This can lead to better cell division and may help cells live longer.
