maybe i'm crazy but i love words that end in -escent and -faction. i have a whole txt file full of them

word of the day: senescent se-NESS-ent growing old, from the latin senescere

i keep thinking it should have something to do with seneschals-- oKAY YEAH IT DOES. IT HAS THE SAME ROOT BECAUSE IT'S ABOUT "OLD SERVANTS." people who have been with the master forever and are thus trusted. lovely.

also has fingers stuck in biology pies, therefore i MUST be invested. it's when you, a cell, has reached a ripe old age of can function but can't split and reproduce. In other words, cell menopause.

Landscape Language senescent (adj) – growing old Summer is senescent, or growing old. One sign of summer plants literally growing old are senescent vine maple leaves turning from green to red as they age.  Vine maples are the earliest trees to turn, so if summer is not old for you, don’t worry! There is still plenty of life in the season... for a few weeks at least. NPS photo of vine maple leaves, 8/30/17. Maple leaves turning red with some green remaining. ~kl

Distinct subtypes of senescent skin cells identified

Senescent skin cells, often referred to as zombie cells because they have outlived their usefulness without ever quite dying, have existed in the human body as a seeming paradox, causing inflammation and promoting diseases while also helping the immune system to heal wounds.  New findings may explain why: Not all senescent skin cells are the same. Researchers from Johns Hopkins University have…

Study established a causal role for age-related pre-existing senescent cells in the severity of COVID-19 symptoms in an aging hamster model.

Selective depletion of senescent cells using senolytic agents mitigated the risk of severe COVID-19 symptoms linked to aging.

Senescent cell turnover slows with age providing an explanation for the Gompertz law | Nature Communications

“A causal factor in mammalian aging is the accumulation of senescent cells (SnCs). SnCs cause chronic inflammation, and removing SnCs decelerates aging in mice. Despite their importance, turnover rates of SnCs are unknown, and their connection to aging dynamics is unclear. Here we use longitudinal SnC measurements and induction experiments to show that SnCs turn over rapidly in young mice, with a…
