Darwin's theory of natural selection provides an explanation for why organisms develop traits that help them survive and reproduce. Because of this, death is often seen as a failure rather than a ...

Experiments and modeling reveal the unexpected structure that can be seen in bacteria grown in mucus samples and biofilms. Scientists at Caltech and Princeton University have discovered that ...

Biologists converted gut bacteria into miniature protein factories that manufacture and release a sustained flow of targeted proteins inside the lower intestines. This technique solves one of the ...

Nanotube bridge networks grow between the most abundant photosynthetic bacteria in the oceans, suggesting that the world is ...

Microscopic imaging revealed how the particles pierce bacterial cell membranes and disrupt their internal structures. At the concentrations needed to kill bacteria, the treatment showed minimal ...

The names themselves date back to 1884, when Danish bacteriologist Hans Christian Gram developed a staining procedure to view bacteria under the microscope. First, he applied a dye, called gentian ...
