Researchers identify gene with functional role in aging of eye

The gene Elovl2 appears to play a significant role in age-associated functional and anatomical aging in mouse retinas. The finding has direct implications for age-related eye diseases, such as macular degeneration. When the expression of the gene was boosted, age-related visual function improved.

Are bigger brains better?

Greater hippocampal volume is not always a reliable predictor of learning and memory ability in older adults. Faster learning was only found in older adults who had both greater hippocampal volume and more uniform white matter connections to other parts of the brain.

Exercise is good for your brain’s gray matter

Cardiorespiratory exercise improves gray matter volume in areas of the brain associated with age-related cognitive decline. The findings add weight to the previous studies which link physical activity to neuroprotection against age-related cognitive decline.

Changes in the immune system explain why belly fat is bad for thinking

Less muscle mass and increased body fat may affect cognition as we age. The link between body mass and declining fluid intelligence may be attributed to different types of white blood cells.
