Mitochondrial dysfunction, including decreased mitochondrial respiration and increased mitochondrial stress, is associated with many major human diseases and casual to many pathological defects.

Pieces of bacteria migrating from the gut to the brain may play a key role in sleep, scientists have discovered, suggesting that the oldest and most basic microorganisms in our bodies are crucial in ...

In two recent studies, researchers at the Indian Institute of Science (IISc) and Unilever have collaborated to develop computational models of bacterial cell walls that can speed up the screening of ...

There are many ways of classifying bacteria. One method is based on the cell membrane. In 1884, a bacteriologist named Christian Gram created a test that could determine if a bacterium had a thick, ...

p73, a binding site for lipopolysaccharide (LPS) on human peripheral blood monocytes was identified using the radiolabeled photoaffinity cross-linker sulfosuccinimidyl 2-(p-azidosalicylamido)ethyl-1,3 ...

Researchers have succeeded in the world's first visualization of a peptidoglycan 'wall' present in the chloroplasts of bryophytes (moss plants). Until now, chloroplasts of green plants were considered ...

Although the role of Toll-like receptors in extracellular bacterial sensing has been investigated intensively, intracellular detection of bacteria through Nod molecules remains largely uncharacterized ...

Researchers have discovered a widespread mechanism in bacteria that enhances the bacteria's defense against environmental threats. The discovery, which may be important for research into developing ...

Focusing on the human pathogen Staphylococcus aureus, new research led by scientists from the University of Sheffield in the U.K., examines how bacteria maintain their unique cell walls and how ...

With delicate hues of purple and pink, a lab technique called gram staining has reliably characterized bacteria for more than a century. Yet many scientists are mistaken about why the vivid method ...
