Only three years after AIDS was described for the first time, in 1984 American and French researchers identified the pathogen causing the immune deficiency disease – the HIV virus. Scientists and politicians reacted prematurely, announcing a rapid solution to the problem. But the development of an HIV vaccine today resembles a “Chronicle of sustained failure”. At the moment, almost unbeknown to the general public, researchers are developing and testing a gene-based HIV vaccine which is rousing great expectations.

There is not much medicine can do when microscopically tiny lesions trigger tumour development in the pancreas. To stop this in the early stages would entail detecting just a few cells from the outside. An interdisciplinary team now wants to make the early stages of cancer visible through molecular imaging, like a “biological magnifying glass”.

The goalkeeper's reactions to penalty shootouts provide a good example of the highly complex control mechanisms for movement sequences.
