The nobel prize in physiology / medicine was recently announced. And it went to a research area I have worked with myself (at Lundbeck), namely HIF / hypoxia biology. We published a paper on our findings, it can be found here:
All animal cells need oxygen in order to use the energy from food (they do this in cellular respiration), but when oxygen levels are lower than normal (hypoxia) they have a very smart way of adaptation. The HIF1 alpha protein! I have made an animation explaining the molecular basics of the mechanism by which HIF do this.
