The Great Pacific Garbage Patch: A marine pollution problem that affects all of us

I am part of the Soft Matter Group, where we are particularly interested in all sorts of applications of soft materials. The project I am working on aims to develop new paints and coatings which are more environmentally friendly than the ones in the market. So I could say I am living proof that you can get a salary for watching paint dry! 


Until now, I have been preaching the benefits and wonders of polymers and plastics (find out why I think we live in a world of plastic spaghetti and  watching paint dry is fun). But today´s post is about their main disadvantage: the effect they have on the environment. Nowadays we use disposable plastic at all times: food trays, plastic cups, carrier bags, and wrapping film, are just a few examples. We are generating tons of plastic waste every day. However, a huge amount of these items are not disposed of properly (recycled) and they mostly end up in rivers and, eventually, in the sea.  And once they arrive there, their fate is determined by the sea surface currents, which moves them from one place to another.

¿Por qué los humanos nos besamos?



Llega el temido día de San Valentín, odiado por muchos pero deseado por otros tantos. Desde La Biothéque queremos aprovecharlo para difundir un poco de ciencia, en concreto la ciencia que hay detrás del beso.
