Ants Live 10 Times Longer by Altering Their Insulin Responses
Queen ants live far longer than genetically identical workers. Researchers are learning what their longevity secrets could mean for aging in other species.
What Causes Alzheimer’s? Scientists Are Rethinking the Answer.
After decades in the shadow of the reigning model for Alzheimer’s disease, alternative explanations are finally getting the attention they deserve.
Epigenetic ‘Clocks’ Predict Animals’ True Biological Age
A statistical analysis of chemical tags on DNA may help unify disparate theories of aging.
Protein Blobs Linked to Alzheimer’s Affect Aging in All Cells
Protein buildups like those seen around neurons in Alzheimer’s, Parkinson’s and other brain diseases occur in all aging cells, a new study suggests. Learning their significance may reveal new strategies for treating age-related diseases.
To Learn More Quickly, Brain Cells Break Their DNA
New work shows that neurons and other brain cells use DNA double-strand breaks, often associated with cancer, neurodegeneration and aging, to quickly express genes related to learning and memory.
Longevity Linked to Proteins That Calm Overexcited Neurons
New research makes a molecular connection between the brain and aging — and shows that overactive neurons can shorten life span.
