An international team led by ETH Zurich and including researchers in Japan has used a new high‑resolution imaging technique to watch, live, as influenza viruses penetrate human cells. The work shows that cells actively engage with the virus, helping to draw it inside in a process that resembles surfing along the cell membrane, and could inform the development of targeted antiviral therapies.
Scientists have developed a revolutionary imaging technique that uncovers the intricate internal architecture of plankton, the ocean's microscopic powerhouses. Using ultrastructure expansion microscopy, researchers visualized over 200 marine species for the first time, mapping evolutionary patterns in their cellular skeletons. This work, stemming from a pandemic-era collaboration, launches a global atlas of plankton diversity.
