In the design of new medicines, it is very important to know how the proteins' functions are characterized. Sandra Izquierdo's doctoral thesis, "�cids (+) i (-) aminociclobutan-1-carbox�lics i la seva incorporaci� en �-p�ptids. Estudi sint�tic i estructural", studied how the secondary structures of the particles that form the proteins, the...

Investigators of the Service of Neurology have stimulated and inhibited parts of the brain supposedly implied. The results discard the role of the prefrontal lobe...
A team of researchers of the UAB have developed a process which could increase the computer storage capacity. This application is due to the study of the magnetical properties of circular structures with submicrometrics size. By means of these tiny disks, the researchers have obtained "Exchange Biased Vortices", that could rise the magnetic...
