The best-selling novel ‘The swarm’ captured the imagination of countless readers with the fascination of marine life. But it also showed how little we understand life in the depth of the ocean.
Scientists at the European Molecular Biology Laboratory (EMBL) and the Max Planck Institute (MPI) for Developmental Biology now explain the remarkable ability of marine zooplankton to swim towards light. Their study, published in the current issue of Nature, reveals how simple eyes of only two cells, sense the direction of light and guide movement towards it.The key is a nerve that connects the eyes directly to the cells that mediate swimming. The research also provides new insights into what the first eyes in animal evolution might have looked like and what their function was.

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
