====== Cell death ======

>Why living organisms inevitably die and what death even means in terms of physics and dynamical systems are still open questions despite the vast advances in molecular biology. Revealing how some cells die — not through biochemical processes but physics — would help to answer them."\\ \\ Source : [[https://basan.med.harvard.edu/sites/projects.iq.harvard.edu/files/xuyouk2024.pdf|Nature, Nature physics, news & views, article, May 2024]]{{:oa_padlock_grn.png?16}}

Simply put, the physical reasons why any cell with access to a reasonable amount of resources, and with a reasonable environment, might spontaneously lose its viability, are largely unknown.

If the cell is a crucial part of an organism, or if groups of cells all 'decide' to expire around the same time, the organism in question may well die. It's estimated that a healthy human loses several billion (previously viable) cells every day.

Cell-death (a.k.a. //Apoptosis//) has been very extensively investigated for many decades, and much progress has been made in identifying different modes of cell-death ([[https://en.wikipedia.org/wiki/Cell_death#Types|ref.]]) but :

>__Despite these recent advances, why death is inevitable for living organisms based on physical laws remains unexplained."__\\ \\ [ Source as above ]
