Archaea—one of the three primary domains of life alongside bacteria and eukaryotes—are often overlooked and sometimes mistaken for bacteria due to their single-celled nature and lack of a nucleus. Yet ...

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

Animals and fungi predominantly use two different modes of cell division -- called open and closed mitosis, respectively. A new study has shown that different species of Ichthyosporea -- marine ...

Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first ...

How did the characteristic pattern of embryonic cell divisions during animal development evolve? Analysis of the multicellular development of an organism related to animals now provides some answers.

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

Using an innovative combination of biochemical experiments and ultra-high-resolution microscopy, a research team at Kiel University has solved the long-standing mystery of how the bacterium B.

When we talk about memories in biology, we tend to focus on the brain and the storage of information in neurons. But there are lots of other memories that persist within our cells. Cells remember ...

Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution. Researchers have discovered a ...

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling.
