Scientists trace an ancient microbe, Asgard archaea, that gave rise to humans, animals, and plants more than 2 billion years ...

Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple ...

Scientists have discovered a single-celled organism in the hot springs of Lassen Volcanic National Park, which is not only ...

Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like this one complicate matters.

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

Scientists have identified tubulin structures in primitive Asgard archea that may have been the precursor of our own cellular skeletons. In 2010, biologists made a shocking discovery. Living in the ...

An international collaboration has published groundbreaking research, shedding light on the most significant increase in complexity in the history of life's evolution on Earth: the origin of the ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...
