Textbook images show peptidoglycan as straight and ordered. The biopolymer peptidoglycan that makes up bacterial cell walls was always assumed to be highly ordered. Textbook images like the one below ...

MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria ...

Biologists from ETH Zurich have discovered speargun- like molecular injection systems in two types of bacteria and have described their structure for the first time.

When scientists discovered how bacteria protect themselves against viral invaders, called phages, in the early 2000s, little ...

Scientists have discovered a bacterium that’s about 5,000 times larger than any other giant bacteria -- large enough to see without a microscope.

A Cornell-led collaboration has devised a potentially low-cost method for producing antibodies for therapeutic treatments.

SYNTHETIC cells made by combining components of Mycoplasma bacteria with a chemically synthesised genome can grow and divide into cells of uniform shape and size, just like most natural bacterial ...
