NewsTwo coronavirus master keys: new study unveils the mechanisms Covid-19 virus uses to enter our cells
To enter our cells, the Covid-19 virus fuses its surrounding membrane with the membrane of the target cell. The fusion peptides of the spike protein function as molecular keys that allow the virus to open the door to the target cell . A new study shows that SARS-CoV-2 does not have just one key, but two.

NewsNew test could dramatically speed diagnosis of hard-to-detect lung infections
Nontuberculous mycobacteria can cause chronic, tuberculosis-like lung infections. Researchers have developed a new diagnostic platform that can identify the precise species of bacteria causing a patient’s infection in just a few hours — a dramatic improvement over the current standard, which can take four to six weeks.

NewsNew method reveals how virus particles can build themselves, molecule by molecule
Researchers have captured the step-by-step assembly of individual virus-like particles, revealing how simple molecular interactions can reliably build these complex biological structures. The process works rather like finding a route through a maze in which only the productive turns lock into place.

NewsNovel database reveals hidden diversity and potential of deep-sea microbes
Scientists have spearheaded Global Ocean Reference Genomes Dark (GORG-Dark), the first global atlas of single-cell microbes living in the aphotic ocean. It contains more than 9,600 genomes from individual microbial cells collected across a broad range of depths and locations, including the Mariana Trench and the Antarctic.
