    Notes: [Auszug] Venus has no significant internal magnetic field, which allows the solar wind to interact directly with its atmosphere2,3. A field is induced in this interaction, which partially shields the atmosphere, but we have no knowledge of how effective that shield is at solar minimum. ...

    Notes: [Auszug] A decisive step in the biosynthesis of many proteins is their partial or complete translocation across the eukaryotic endoplasmic reticulum membrane or the prokaryotic plasma membrane. Most of these proteins are translocated through a protein-conducting channel that is formed by a conserved, ...

    Notes: [Auszug] Tuberculosis (TB) is not only completely treatable, it is curable and controllable, and has been so for decades. So it is appalling that the disease is currently flaring up around the world in an epidemic of co-infection with HIV, which is also associated with a frightening increase in strains of ...

    Notes: [Auszug] Hedgehog (HH) morphogen is essential for metazoan development. The seven-transmembrane protein smoothened (SMO) transduces the HH signal across the plasma membrane, but how SMO is activated remains poorly understood. In Drosophila melanogaster, HH induces phosphorylation at multiple Ser/Thr ...
