A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...
Biobots could one day be engineered to deliver drugs and clear up arterial plaque. Kriegman et al. 2020/PNAS, CC BY-SA Life and death are traditionally viewed as opposites. But the emergence of new ...
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. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...
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 ...
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 ...
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 ...
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 ...
The original version of this story appeared in Quanta Magazine. Once upon a time, long ago, the world was encased in ice. That’s the tale told by sedimentary rock in the tropics, many geologists ...
