News‘Pink berries’ reveal how bacteria survive a viral epidemic
Like humans struggling to get through the COVID-19 pandemic, bacterial cells need social distancing to thwart viruses. But in some situations, such as inside elevators or within the candy-colored bacterial structures known as “pink berries,” staying apart just isn’t feasible. Source: Lizzy Wilbanks “Pink berry” bacterial structures. These ...
