Gut bacteria evolve rapidly in response to different diets, UCLA evolutionary biologists report in a new study. The ...

The plasticity of macrophages depends on the spatial distribution, surrounding cell types, external microenvironment and extrinsic stimuli. This represents not only their capability to rapidly adapt, ...

An organism as a tenant in another - in biology, this often works quite well. ETH researchers have now shed light on how such a partnership of a cell in a cell can establish. Endosymbiosis is a ...

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 ...

In a study published in Nature Ecology and Evolution, scientists show that the SAMD9 and SAMD9L genes, key players in ...

Scientists have discovered a previously unknown strain of microbe after analyzing samples taken from China's Tiangong space station. The new microbe strain, officially named Niallia tiangongensis, was ...

Engineered bacterial cells (purple) activate several parts of the immune system to attack tumor cells (gray). Credit must be given to the creator. Adaptations must be shared under the same terms.

Scientists say they have shed new light on how bacteria protect themselves from certain phage invaders -- by seizing genetic material from weakened, dormant phages and using it to 'vaccinate' ...

A bizarre bacteria has been discovered with an ability previously thought impossible for its kind. This strange discovery could shine a light on how some of our earliest single-celled ancestors formed ...

As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are ...
