What is senotherapeutics?

• A. Drugs to remove old 'senescent' cells that cause aging and inflammation; research is active but results are early stage.
• B. A device for measuring telomere length.
• C. A method for digital immortality.
• D. A dietary plan.

Answer: (A)

Senotherapeutics are therapies that target cells that have entered a state called senescence, where cells stop dividing and release inflammatory signals that contribute to aging and disease. The idea is to reduce the burden of these senescent cells or their harmful secretions. The described option fits this by talking about drugs that remove old senescent cells to combat aging and inflammation, with the caveat that research is active and results are still early—this reflects the current stage of the field, where promising approaches are being tested but aren’t yet proven standard treatments.

The other ideas aren’t about clearing senescent cells: measuring telomere length is a diagnostic tool, not a therapy; digital immortality is a sci-fi concept, and a dietary plan doesn’t target senescent cells.
