In living things, diffusion allows substances to move in and out of cells. It's how red blood cells distribute oxygen through the body. When empty blood cells enter the lungs, which have an ...

These compartments – artificial cells, each a mere millionth of a meter in depth – are connected via thin capillary tubes, creating a network that allows the diffusion of biological substances ...

Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on ...

into or out of the cell. Products of digestion, dissolved in water, can pass across the wall of the small intestine by diffusion. Their concentration is higher in the small intestine than their ...

"Understanding these mechanisms requires a synthesis of stem cell biology and mass transfer physics, where physical diffusion phenomena affect neurodevelopmental cues that define cell identities ...

Glial cells, among other things, can support and protect neurons ... hundreds of combinations until they found an effective formula comprising “four core drugs.” “By using four molecules ...

Actin-based vesicular trafficking of Cdc42, leading to a polarized concentration of the GTPase, has been implicated in cell polarization, but it was recently debated whether this mechanism allows ...
