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 tree of life. The findings challenge the common perception that cell-in-cell events are largely restricted to cancer cells. Rather, these events appear to be common across diverse organisms, from single-celled amoebas to complex multicellular animals.
Scientists have taken a step closer to replicating nature s processes of self-assembly. The study describes the synthetic construction of a tiny, self-assembled crystal known as a pyrochlore, which bears unique optical properties. The advance provides a steppingstone to the eventual construction of sophisticated, self-assembling devices at the nanoscale roughly the size of a single virus.
Many biological structures of impressive beauty and sophistication arise through processes of self-assembly. Indeed, the natural world is teeming with intricate and useful forms that come together from many constituent parts, .

In a new review paper, Carlo Maley and Arizona State University colleagues 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 tree of life.
