The challenge came from the Director of the Bone Bank at the University Hospital of Coimbra in Portugal. "Can you find a way of making the cartilage cells in bone grafts survive deep freezing?" The question was interesting, but we needed to understand the problem in more detail. [Mas Informacion]

Be it a beauty contest or a track event, on the field or off the field, the competitive spirit urges us to be the best -the fastest, the strongest, the wisest- in every walk of life. Science is no exception, and the astronomical observatory of the Jagiellonian University in Krakow has discovered a new radio galaxy, which is the largest known object yet in the universe -a cosmic record, no less-.

These words from the Austrian author and actor Helmut Qualtinger drive to the heart of a simple but often neglected problem: innovations shake up the status quo, which is precisely why we often have trouble dealing with them. In innovation processes, resistance and difficulties are not the exception but rather the rule. This fact takes on particular importance when we consider that knowledge rapidly becomes obsolete in our globalized world, and that product and process lifecycles are becoming ever shorter under increasing cost pressures and competition. Now, more than ever, those who hope to survive in science and business must implement innovative ideas quickly. [Mas Informacion]

Calor, calor. La temperatura de la superficie de la Tierra contin�a in crescendo, como indica un an�lisis del Instituto Goddard para Estudios Espaciales de la NASA (GISS, seg�n sus siglas en ingl�s), que muestra como ha variado el clima comparando 2011, el noveno a�o m�s caluroso desde 1880, con la media global de mediados del siglo XX. El incremento fue de 0,51 grados cent�grados. Un hecho que, seg�n los cient�ficos, confirma la tendencia al alza de este par�metro, fundamental para conocer la salud del planeta. Y ha aumentado sobre todo en el siglo XXI, que ostenta un preocupante r�cord: los 10 per�odos m�s calurosos se concentran a partir del a�o 2000, con 2005 y 2010 a la cabeza, en empate virtual.

Els recorreguts del GPS no tenen context i la mirada de Google Maps �s tan �til i internacional com estandarditzada i freda. Ara com ara no hi ha cap altre mapa de Catalunya com l'atles de carreteres que reedita Geoestel. I aquest mapa nom�s el tenim nosaltres. El millor, emper�, �s que �s molt m�s que un atles, �s un excel�lent llibre d'economia, d'hist�ria i de narrativa. [Mas Informacion]
