Cellular Metabolism
A Columbia researcher argues that everything from stress to aging comes down to how energy moves through your body.
By treating the human body as an information system, scientists are using AI to simulate cells, visualize hidden biology, and detect disease at its earliest — and most preventable — stages.

“Can we push these cells to do something other than what they normally do?" asks developmental biologist Michael Levin. "Can they build something completely different?”
The findings suggest that biochemical and physical effects of exercise could help heal nerves.
“Having more stem cell activity is good for regeneration, but too much of a good thing over time can have less favorable consequences.”
Long overlooked, menstrual stem cells could have important medical applications, including diagnosing endometriosis
If you eat a diet full of refined grains, high-sugar drinks, and sweets, there's a good chance you have too much insulin.

While Y chromosome loss was first observed in 1963, it was not until 2014 that researchers found the link to a shorter life span.
For over three decades, toxic proteins were believed to cause Alzheimer’s disease. However, recent studies suggest it might be metabolic reprogramming.
