Epigenetic ‘Clocks’ Predict Animals’ True Biological Age
A statistical analysis of chemical tags on DNA may help unify disparate theories of aging.
Why Do We Get Old, and Can Aging Be Reversed?
Everybody gets older, but not everyone ages in the same way. In this episode, Steven Strogatz speaks with Judith Campisi and Dena Dubal, two biomedical researchers who study the aging process.
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.
Deep Curiosity Inspires The Joy of Why Podcast
The noted mathematician and author Steven Strogatz explains how the conversations with experts in his new Quanta Magazine podcast address his lifelong fascination with timeless mysteries.
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.
Dueling Brain Waves Anchor or Erase Learning During Sleep
While we sleep, one kind of slow brain wave helps to reinforce memories, but a competing wave weakens them.
Cellular Life, Death and Everything in Between
The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.
‘Functional Fingerprint’ May Identify Brains Over a Lifetime
A unique neurological “functional fingerprint” allows scientists to explore the influence of genetics, environment and aging on brain connectivity.
