We tend to view ourselves and the complex cells that build us as a distinct branch of the tree of life from the compact, ...

All cells in animals, plants, fungi, and protists share a fundamental characteristic: they are eukaryotic cells—complex cells ...

Billions of years ago, life on Earth made a leap from simple microbes to complex cells with nuclei and organelles. New research reveals that our archaeal ancestors already possessed advanced molecular ...

In many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. These creatures belong to a domain of life called the archaea ...

An international research team led from Uppsala University in Sweden has identified a metabolic shift in ancient microbes that helps explain how Earth’s first complex cells arose from a merger of ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

Researchers at the Centre for Genomic Regulation (CRG), and at Harvard Medical School have used mathematical modeling to show how individual cells appear capable of learning, a behavior once deemed ...

Research and drug discovery are undergoing a transformation, driven by the rise of 3D cell culture models that better replicate human biology. Unlike traditional 2D cultures and animal models, which ...
