Another case of "fixing the problem we created in the mice in the first place". While good for reproducability and analyzing possible root causes it is frustratingly disappointing.

I would really want to see is the process on actual senior lab mice - that would highlight other factors untreated and how transferrable it is to the general case for mice - let alone humans. If open-ended trial mice reach unprecedented ages that would have major implications.

The article title should read, "Scientists able to temporarily induce some symptoms of aging in young mice". If they could have reversed symptoms of aging in actual old mice they would have done it.

Hair loss cure has been around for a while, at least for MPB. Been taking finasteride for almost a decade and haven't lost any hair. Most guys are scared away by rare but serious side effects. But most of the problem seems to be getting guys to take pills regularly at all

What a time to be a mouse

Look at the picture of the mouse - it’s not aging, it’s dying. Yes, they “reverse” the condition, but only by the cessation of giving these little guys poison (doxycycline, a harsh antibiotic). This could have been called “high doses of doxycycline almost kills mice.”

Ray Peat proven right once again.

We hear of these kind of studies time and time again yet never see anything materialise for humans.
