This article was originally featured on The Conversation. Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism ...

Researchers in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University have uncovered something new in one of the most studied organisms on Earth, and their ...

Until one or two billion years ago, life on Earth was limited to a soup of single-celled creatures. Then one fateful day, a lonely cell surrendered solitude for communal living. It developed a chance ...

Researchers find that oxygenation of Earth's surface is key to the evolution of large, complex multicellular organisms. If cells can access oxygen, they get a big metabolic benefit. However, when ...
