The Trade-off Between Physiological Authenticity and Experimental Convenience: Navigating the Cellular Foundation of ...
Experiments reveal that unsaturated lipid membranes promote vesicle fusion and DNA retention during freeze–thaw cycles, highlighting icy environments as potential drivers of protocell evolution. Today ...
The death of an organism does not spell the end for its cells, according to new research. Cells have been shown to continue to function even after the organism they originated from is deceased, often ...

Life May Have Started as Sticky Goo, Long Before Cells Even Existed
Scientists have many theories about how Earth's raw materials turned into living cells, but a new proposal is particularly slimy. In a recent paper, an international team argues that life may have ...
What we breathe out becomes fuel for forests. But inside our own bodies, CO₂ has a secret life. It sparks chemical reactions, shapes metabolism, and may even act as a signaling molecule—and a new tool ...
Billions of years of evolution have made modern cells incredibly complex. Inside cells are small compartments called organelles that perform specific functions essential for the cell’s survival and ...
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 ...
Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines nearly every aspect of their functioning. This ...
