“infusing aged animals with cerebrospinal fluid from younger mice can boost SRF activation and actin assembly to more youthful levels”
It seems like we should transplant more than organs.
- yosito 3y agoWe could all become vampires. The old consuming the young to prolong life and youth. It's a common theme in science fiction and fantasy.
- atmavatar 3y agoWe've already seen the wealthy consume the blood of the young (in the form of transfusions) to try and live longer. See: https://www.bbc.co.uk/bbcthree/article/347828f8-6e7f-4a9b-92ab-95f637a9dc2e https://www.bbc.co.uk/bbcthree/article/347828f8-6e7f-4a9b-92...

- collegeburner 3y agothis poses a huge risk of creating a prion epidemic. things like CSF are very, very risky
- tomcam 3y agoUnderrated comment
- ChadNauseam 3y agoA larger risk than that which comes from blood transfusions? It seems like prion diseases tend to be brain-based, but I'm not sure why
- arghwhat 3y agoThe prion protein, which is the specific protein that can misfold to cause prion disease, is vastly more abundant in nervous tissue.
- the8472 3y agoSo we should only drink the blood and spinal fluid of newborns grown in vats and carefully monitored to make sure that they only contain healthy proteins.
- RobotToaster 3y agoMy guess is they don't actually want to do this on humans. This is just the first step, finding out if something in young CSF works. Next you figure out exactly what component of it is responsible, and figure out how to synthesise it.

- Y_Y 3y agoHaving seen the harrowing Japanese documentary series Shingeki no Kyojin, prions are the least of my worries.
- hfucvyv 3y agoI'd donate for MS patients even if it was just a temporary solution.
- OneLeggedCat 3y agoPeter Thiel emphatically nods head in agreement
- mullingitover 3y agoDidn't we go through this with youthful blood and find that simply diluting with saline and albumin had the same effect?

- saurik 3y agoI copy/pasted the exact text of the comment you are responding to into Google--including the "Didn't we" and the question mark--and it pulled up the source you couldn't find. https://www.economist.com/technology-quarterly/2023/09/25/what-the-young-can-give-to-the-old https://www.economist.com/technology-quarterly/2023/09/25/wh... > In 2020 Irina Conboy of the University of California, Berkeley, and her colleagues found that replacing half of an old mouse's blood with just albumin, a blood protein, and saline solution had the same rejuvenating effect as young-mouse blood. Old blood may need filtering and dilution, not supplementing. https://news.berkeley.edu/2020/06/15/diluting-blood-plasma-rejuvenates-tissue-reverses-aging-in-mice https://news.berkeley.edu/2020/06/15/diluting-blood-plasma-r...
