Neural progenitor cells keep dividing in the adult brain, offering new hope for memory, learning, and repair. Originally published by Neetika Walter , Updated: Jul 03, 2025 06:46 PM EST Representational image of brain neurons. iStock Photos For decades, scientists believed the human brain stopped producing new neurons after childhood . This long-held view painted the adult brain as a fixed organ, incapable of generating fresh cells in the very region responsible for memory and learning. But a landmark new study turns that dogma on its head, offering the clearest evidence yet that adult humans continue to form new neurons well into the old age . Read more   

Originally published by Christoph Schwaiger at livescience.com on July 1, 2025 Scientists say they captured 3D images of a new organelle they're calling a "hemifusome," which may be a recycling center in human cells.   The green and orange structures in this image are hemifusomes, newly discovered organelles that may represent a previously unrecognized pathway for recycling in human cells. (Image credit: Courtesy UVA Health) A new organelle has been discovered in human cells — and scientists call it a " hemifusome ." Like the full-size organs in our bodies, the organelles within cells are specialized structures that carry out specific functions . While observing filaments that maintain the shape of cells, Seham Ebrahim , an assistant professor at the University of Virginia , and her team noticed a new structure that was consistently appearing in the 3D images they were making .
