Optimal packing problems have inspired mathematicians for centuries. Biophysicists now add a layer to the question: How do chloroplasts arrange themselves optimally within cells, when the meaning of ...

A team of researchers led by the University of California San Diego has discovered a new way to make yeast cells more ...

Plenty of useful facts are taught in biology classes − from the nutrients necessary for the human body to the mechanisms that ...

Researchers have developed a novel electromagnetic cell sorting technique for separating different cell types.

Apoptosis is characterized by a series of dramatic perturbations to the cellular architecture that contribute not only to cell death, but also prepare cells for removal by phagocytes. Apoptotic cell ...

Heatstroke is a potentially fatal condition characterized by elevated body temperature and central nervous system (CNS) dysfunction. Impaired thermoregulation may arise from prolonged passive exposure ...

Prokaryotes are organisms whose cells lack a membrane-bound nucleus, mitochondria and other membrane-bound organelles; they include bacteria and archaea. All the intracellular water-soluble components ...

Abstract: The authors describe two versions of a two-dimensional (2-D) cell model that contains three circular membranes representing the plasma membrane (PM) and single bilayer approximations to both ...
