The cells that stop dividing but refuse to leave
Senescence is one of the most studied ideas in the biology of ageing. Here is what the term actually means, and where the honest edges of the science are.

Careful reporting on biology, longevity, vision, medicine, and the capital that decides which questions get asked. We explain what is known, mark clearly where the evidence stops, and never tell you what to do about your own body.

Read the piece →The eye is often described as a camera. The comparison is useful for optics and misleading for almost everything else.
Read the piece →Transplantation is often told as a story about surgery. Much of the real constraint is a story about time and temperature.
Read the piece →Funding structure is not a footnote to scientific progress. It is one of the main forces determining which questions get asked.
Read the piece →Mitochondria are described in every textbook as the powerhouse of the cell. The more interesting fact is that they carry their own separate DNA.
Read the piece →The gap between a promising laboratory result and an accepted treatment is not bureaucracy. It is the process by which a claim earns the right to be believed.

The machinery of the living cell, reported plainly.
Browse →What ageing is, and what science can and cannot yet do about it.
Browse →The eye, the retina, and the long effort to restore sight.
Browse →How treatments are built, tested and judged.
Browse →Who pays for discovery, and how that shapes what gets found.
Browse →We report on research. We do not tell you what to take, what to stop, or what to do about a condition. That conversation belongs with a clinician who knows your history.

A result in cells is not a result in people. Where the evidence stops, we say so in the same paragraph rather than at the bottom of the page.
