Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them navigate toward food sources. In multicellular organisms, growth ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

Living in a murky lake around Mexico City, surrounded by aggressive and cannibalistic neighbors, the axolotl lives at ...

Cells are the smallest units of life. But even within the same tissue or organ, they are not all identical. New variations arise continuously during cell proliferation. While genetic mutations alter ...

The cell sounds idea came to him in 2001 after a ... and excitement at the phenomenon of cellular motion—what inspired nature to create such a mechanism and to really understand in depth what ...

"Cytotoxic agents from nature lead to an increased incorporation of polyunsaturated fatty acids into the membrane of cancer cells. This makes them more susceptible to ferroptosis, a type of cell ...

And it's tempting to seize upon the cells as a simple explanation for the basis of our species' complex social nature. But Allman knows that's a stretch. His theory has its skeptics ...

Take the evolution of sex, for instance. To make the move from asexual to sexual reproduction, nature took a system by which parent cells reproduced simply by dividing (asexual reproduction ...
