The search for new energy sources to power mankind’s increasing needs is currently a topic of immense interest. Hydrogen-powered fuel cells are considered one of the most promising clean energy alternatives. While intensive research efforts have gone into developing ways to harness hydrogen energy to fuel our everyday lives, a natural example of a living hydrogen-powered ‘fuel cell’ has gone unnoticed. During a recent expedition to hydrothermal vents in the deep sea, researchers from the Max Planck Institute of Marine Microbiology and the Cluster of Excellence MARUM discovered mussels that have their own on-board ‘fuel cells’, in the form of symbiotic bacteria that use hydrogen as an energy source. Their results, which appear in the current issue of Nature, suggest that the ability to use hydrogen as a source of energy is widespread in hydrothermal vent symbioses.

Optoelectrical Sisyphus cooling of polar molecules reveals the potential to investigate molecular gases in the realm of nanokelvins, i.e. near absolute zero. The cooling developed by a group of researchers headed by G. Rempe at the Max Planck Institute of Quantum Optics could be useful for quantum information processing, as a quantum simulator, as well as for the physics of many-body systems, such as the preparation of Bose-Einstein condensates.

Life-freindly planets can rather exist in the neighbourhood of metal-poor stars, as study of the Max Planck Institutes for Solars System Research and for Chemistry shows. These stars emit more high energy UV radiation which favours the formation of a life protecting atmosphere.

Six months after its launch, the James Webb Telescope has delivered its first images. They show fascinating glimpses of distant galaxies as well as turbulent scenarios of the birth and death of stars. In addition, the space observatory has captured the spectrum of an exoplanet. „It all looks fantastic and even exceeds our high expectations,“ says Oliver Krause from the Max Planck Institute for Astronomy in Heidelberg. There, his team had developed and built important components for the hardware over the past few years.
