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 continúa in crescendo, como indica un análisis del Instituto Goddard para Estudios Espaciales de la NASA (GISS, según sus siglas en inglés), que muestra como ha variado el clima comparando 2011, el noveno año más caluroso desde 1880, con la media global de mediados del siglo XX. El incremento fue de 0,51 grados centígrados. Un hecho que, según los científicos, confirma la tendencia al alza de este parámetro, fundamental para conocer la salud del planeta. Y ha aumentado sobre todo en el siglo XXI, que ostenta un preocupante récord: los 10 períodos más calurosos se concentran a partir del año 2000, con 2005 y 2010 a la cabeza, en empate virtual.
