    Accurately computing the electronic properties of a quantum ring

    A promising approach to study condensed-matter systems is to simulate them on an engineered quantum platform14. However, the accuracy needed to outperform classical methods has not been achieved so far. Here, us...

    Microglia play a role in mediating the effects of cytokines on the structure and function of the rat pineal gland

    The role of the pineal gland in regulating immune function has been extensively investigated. However, there is little information about possible feedback mechanisms of immunological factors on pineal gland n...
