As the volume increases, the surface area does not increase at the same rate. When the surface area to volume ratio is large, there is a lot of surface area for diffusion and not much volume to travel ...

In a recent study, NASA-supported researchers gained new insight into the lives of bacteria that survive by grouping together as if they were a multi-cellular organism. The organisms in the study are ...

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 ...

How do living organisms that lack a brain or nerve cells make decisions? In a new study published in May 2021 in the Proceedings of the National Academy of Sciences of the United States of America ...

Washington & Alex Pozhitkov: 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 ...

A single genetic mutation may have been responsible for allowing multicellular life – and eventually humans – to evolve on Earth. Biologists have found a lone gene capable of turning single celled ...

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

A fossilised prehistoric organism discovered in 2017 has led scientists to conclude that eggs emerged long before the first animals evolved, implying that they came before chicken. Chromosphaera ...

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so distantly related to each other as they ...
