NewsOrigin of life: How microbes laid the foundation for complex cells
Researchers examining links between Asgard archaea and eukaryotes have shown that Asgard tubulins form similar microtubules, albeit smaller than those in their eukaryotic relatives. Unlike actin, these tubulin proteins appear in very few species of Asgard archaea.

NewsAntibody-based therapy is several steps closer to treat lethal mucormycosis
A new paper discusses the use of monoclonal antibodies to target a key fungal cell surface protein, CotH, which enables the Mucorales fungus to invade human cells and cause mucormycosis, which has high mortality rates in people with weakened immune systems.
