Bacteria come in all shapes and sizes -- some are straight as a rod, others twist like a corkscrew. Shape plays an important role in how bacteria infiltrate and attack cells in the body. The helical ...

Scientists have long known that bacteria come in many shapes and sizes, but understanding what those differences mean has remained a major challenge, especially for species that can’t be grown in the ...

Blow up a long balloon and two things happen: it gets longer and it gets wider. Now imagine a living cell that inflates itself under enormous pressure and yet only grows longer, never adding width.
