Studying protein changes in the kidneys as we age, as well as the transcription of genes into proteins, helps provide a full picture of the age-related processes that take place in these organs.
Despite the prevalence of Alzheimer’s, there are still no treatments, in part because it has been challenging to study how the disease develops. Now, scientists have uncovered new insights into what goes awry during Alzheimer’s by growing neurons that resemble — more accurately than ever before — brain cells in older patients. And like patients themselves, the afflicted neurons appear to lose their cellular identity.
Previous research has shown a link between the duration of a woman’s reproductive life span and her overall metabolic health. By analyzing data from successive surveys spanning the 1959-1962 National Health Examination Survey I through the National Health and Nutrition Examination Survey for 2017-2018, researchers investigated factors that may be driving that link for U.S. women, including an increase in age at natural menopause.
Researchers have identified molecular signatures of the aging process in mice.
It makes evolutionary sense for long-lived animals to have complex social relationships – such as friends and enemies – researchers say.
It’s not just your legs and heart that get a workout when you walk briskly; exercise affects your brain as well. A new study shows that when older adults with mild memory loss followed an exercise program for a year, the blood flow to their brains increased.
It’s important to take steps to prevent cognitive decline before changes to the aging brain take hold. Primary care is an ideal setting to address specific risk factors early and throughout life that can prevent cognitive decline.
