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 ...

Despite rapid advances in reading the genetic code of living organisms, scientists still face a major challenge today—knowing ...

Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study -- conducted using E. coli ...

They derive their energy from differences in the concentration of hydrogen ions across some of these membranes ...

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 ...

New research into antimicrobial peptides, small chains of amino acids able to damage bacterial cells, shows why some peptides are more effective at doing that and also why some cells are more ...

Viruses are so simple in their structure, they may not even qualify as living things. Yet, they are ruthless in their robotic ...

Imagine visiting a mangrove in the Caribbean and discovering a human as tall as Mt. Everest. Something like that happened to marine biologist Jean-Marie Volland — except instead of a human, he ...

Researchers at the University of Toronto have discovered that bacteria can drive stem cell regeneration to repair the ...

Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study published in the journal eLife. The ...
