Researchers from Arizona State University, observed improvements in brain functions among older bees that turn their attention back to nursing the larvae. When the young bees, responsible for brood care, were removed from the hive, some of the older foragers assumed their work. Bees that returned to caring the larvae showed an increased ability to learn and less signs of aging normally shown by older bees (worn wings, hairless bodies, and more importantly, loss of brain function). The scientists also detected proteomic changes in the brains of the bees that had learned new things. One of these proteins, which is also found in humans is known to protect against dementia, including Alzheimer’s disease. The results presented highlight the importance of psychological balance in the elderly and indicate that changing how you deal with your surroundings can help our brains stay younger.
