However we see that in the Soviet Union, places of science remained private property, administered by either private institutions or a state which claimed to be in control of the people, while it was clearly not. The whole Soviet model collapsed very early one because certain factions were banned, and their members executed. I do not think that this is the best that we can do. However I think that the solution, however utopian it sounds, lies in abolition of private property because otherwise we are still beholden to the whims of speculators and their profits rather than the interest of the community. Even if you only democratised science, this would be problematic; the scientists need to eat, and I would argue that they shouldn't have to eat only if the State or a private institutions tells them that they can eat.
There are other examples to go along with what you said. I can't remember the source, but there was a time in the Soviet Union in which scientists wished to implement a much better system of central planning which took into account input and output tables continuously; whether or not the computer power existed at the time I don't know, but the system was quickly shut down by the Soviet bureaucracy - I think because it posed a threat to the power of the State. This is why I tend to by more sympathetic to anarchist ideologies (as a questioner at the end of the presentitaion mentions), because by destroying the material conditions of the state then the state ceases, what you describe as happening has less chance to take hold.
This is why Communism is an anarchist ideology, in recognition of the very problem you have mentioned. Modern day Communists such as Zizek and Badiou accept this, and Badiou urges us to continue with the Communist Hypothesis[0]. The Soviet model was initially radical, but it was not radical enough to overcome the power structures which were much more entrenched than the founders of the revolution thought. So I still think Communism is the answer, but in what way is yet to be found out, and the debate fiercely rages. It's not that I think Lysenkoism is better than what we have currently (including all our junk "science" coming from here and there), it's that I think there is a solution superior to both situations, namely, in the reduction of power of the state and the diminishing of nationalism by making a global revolution as Marx's internationalist roots envisioned. It's not the abolition of private property that was the cause of Lysenkoism, it was exactly what we see now - rigid state bureaucracy and private institutions.
