Científicos en directo

I read a news article which was titled Cientificos en directo. When I translated it the gist of the article was that there are many scientific strides being made. Also, there is a fair going on in La Pedrera for the next few days called Recerca en directe. At this fair, people interested in science can see, touch, and test some of the new scientific discoveries. I thought this article was interesting because i would have never known that this type of fair would be in Barcelona. It is interesting to think that Barcelona has a fair about strides in science because its not something i would generally associate Barcelona with.  The link to this article is http://www.elperiodico.com/es/noticias/barcelona/cientificos-directo-1699781
