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

A new study provides new insights into processes behind the evolution of microorganisms and describes what it means for existing bacterial classification approaches. New research from Dartmouth ...

Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

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 ...

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 ...

Biofilms are conglomerates of bacteria and other organisms, which are feared in medicine as well as other areas because they can contain pathogens and are highly resistant to treatment. Chemists at ...

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, ...

New research from Dartmouth College raises questions over how scientists should interpret observed groupings of bacteria. The study advises caution with the assumption that bacterial clusters are ...
