Nuclear Pores Captured on Film

Video imaging by high-speed atomic force microscopy captures a nuclear pore complex at work

Zooming into a nuclear pore complex using a high-speed atomic force microscope reveals the selectivity barrier that filters the traffic of molecules passing between the cytoplasm and nucleus in eukaryotic cells. This is comprised of intrinsically disordered proteins known as FG Nucleoporins that resemble highly dynamic molecular “tentacles”.

    Spread of a novel SARS-CoV-2 variant across Europe in summer 2020

    Researchers from Basel and Spain have identified a novel SARS-CoV-2 variant that has spread widely across Europe in recent months, according to an un-peer-reviewed preprint released this week. While there is no evidence of this variant being more dangerous, its spread may give insights into ... more

    An artificial cell on a chip

    Researchers at the University of Basel have developed a precisely controllable system for mimicking biochemical reaction cascades in cells. Using microfluidic technology, they produce miniature polymeric reaction containers equipped with the desired properties. This “cell on a chip” is usef ... more

    A tiny instrument to measure the faintest magnetic fields

    Physicists at the University of Basel have developed a minuscule instrument able to detect extremely faint magnetic fields. At the heart of the superconducting quantum interference device are two atomically thin layers of graphene, which the researchers combined with boron nitride. Instrume ... more
