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 ...

Throughout evolution, pathogenic microorganisms, such as bacteria, viruses, and fungi, have developed sophisticated defense ...

Researchers used biochemical techniques and electron microscopy to uncover the structure of the bacterial MotA protein, which forms part of the propeller motor (flagellum). Three-dimensional analysis ...

Bacteria are also able to communicate with each other through chemical signals, a behavior known as quorum signaling (QS). These chemical signals spread through a biofilm that colonies of bacteria ...

Science paper identified two proteins that combine to form pentamers, which along with previously discovered hexamers, create a preliminary atomic model. Researchers identified proteins that play a ...

Tuberculosis is the world's leading infectious cause of death, killing more than one million people each year. When the antibiotic bedaquiline was introduced in 2012, it was the first new tuberculosis ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

Vol. 395, No. 1/2, Part I: Special Issue Biochar and the Plant-Soil Interface (October 2015), pp. 415-427 (13 pages) Background and aims Peanut yield and quality are seriously compromised by ...

For the first time researchers have deciphered the near-atomic structure of filaments, called 'pili', that extend from the surface of bacteria that cause traveler's diarrhea. Without pili, these ...
