Since 2014 there is already Einsteinium (EMC2) which is a coin designed to reward science and education. EMC2 is a PoW coin without any premine and already totally decentralized, with a good capitalization, good volumes and an excellent team with an exciting roadmap. So which is the need to create now something similar, and to sell it in an ICO? Just explain it to me

While they have good volume and did support a couple science projects, they do not tackle with the main "pain" points in the current scientific landscape, which are mainly : limited access to research output, lack of collaboration and transparency between research groups, reproducibility of published research experiments and the greed of the traditional scientific publishers. In this sense our project is unique and we are using the blockchain technology at it's full potential (creating Proof of Existence for submitted manuscripts, unique ID's for researchers etc.).
If my explanation was not sufficient, I would suggest a quick read of our article here:
