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.

Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
