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 ...

The mystery of how multicellular life evolved has long baffled scientists, who've spent years trying to understand how solitary single-celled organisms began living in unison and triggered the ...

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

Given the right conditions, certain types of cells are able to self-assemble into new lifeforms after the organism they were once part of has died. When you purchase through links on our site, we may ...

Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier ...

Life emerged on Earth some 3.8 billion years ago. The “primordial soup theory” proposes that chemicals floating in pools of water, in the presence of sunlight and electrical discharge, spontaneously ...

A new study shows that multicelled organisms like the metazoan daphnia (pictured) require a tenfold increase in energy compared with protists for their growth, maintenance and survival. The high cost ...

This article is a summary of Roy Ratcliffe’s recently released book ‘Life on Earth’ (Past, Present and Future)’. Of all the millions of species of life that have existed on earth over billions of ...

Researchers describe cell-in-cell phenomena in which one cell engulfs and sometimes consumes another. The study shows that cases of this behavior, including cell cannibalism, are widespread across the ...

That’s what pops to mind when I look at Sebastian Hess’ photos of a kind of plump, violent, single-celled creature he collected from a pond rich in sphagnum moss in southern Germany. The ...
