I'm not sure I understand the point of this sort of protest. Research is ongoing in medical fields. Lobbying to direct research funding from some areas to others might be helpful but I don't see what a general protest like this does.
A good excuse for them too meet and socialize irl.

This was first legally approved political action of Russian transhumanists. Symbolically it was near Karl Marx monument which is opposite to the Big theater.
Main slogans:
"Stop aging - it is main goal for the state".
"Live 150 years!"
"Immortality!"
"Right to live!"
"We are against death"
The main cognitive bias that played here was that we will be crashed by police. Nothing happened.
