Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of ...

Spermine, a small but powerful molecule in the body, helps neutralize harmful protein accumulations linked to Alzheimer’s and Parkinson’s. It encourages these misfolded proteins to gather into ...

Plants and trees may seem pretty passive, but behind the scenes, their cells are working hard to put on a magic show. In this episode of Crash Course Botany, we’ll explore how the processes of ...

Scientists have uncovered a surprising new healing mechanism in injured cells called cathartocytosis, in which cells "vomit" out their internal machinery to revert more quickly to a stem cell-like ...

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don't code for proteins, called introns, are cut ...

A new study from WashU Medicine identifies a previously unknown way that cells purge waste in a process that helps them revert to a stem cell-like state to promote healing after injury. Here, three ...
