“Scientists are very optimistic because we think finding answers is always possible.”

In the 1980s, when I was studying chemistry at the University of Zaragoza, I was surprised to see that chemistry was at the center of other sciences. Almost everything had to do with chemistry: new materials (plastics, alloys…), catalysts, etc. But I also realized that chemistry was essential to answer deep questions. For example, in those years the origin of life was attracting much attention and it was clear that the response should be chemical. Society needed new drugs: antibiotics, molecules against cancer… And the problem of energy was in full swing and photovoltaic materials were beginning to become important… At the same time, I realized that the public image of science, especially chemistry, was getting worse. For me this was incomprehensible, because the results and advantages of science were uncovered. Unfortunately, I think today this problem is more serious.

The truth is that the main questions have no answer. But this is not bad news, I think it's about the charm of science: give partial answer to every question, just to create the next one.

In this sense, scientists are very optimistic, because we think finding answers is always possible. Nature will tell us whether this optimism was justified or not. And we must not forget that the questions and needs of four decades ago are still with us.

As for our research, we are working on three main lines that are totally different from the outside. On the one hand, new catalysts, called EHU-Phos, have been invented for the development of new products of great interest. On the other hand, together with particle physicists, we have completed an investigation to know why this universe is made of matter and not of anti-mating. Finally, with the help of biologists and doctors, we are developing cutting-edge therapeutic molecules. We would really like these new molecules to be useful. In any case, we hope that the knowledge acquired with these research involves a small step.
