Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the contents in, and forms an intracellular vesicle called an endosome. This vesicle travels through ...

These membranes, composed of flexible lipid bilayers, can reshape and remodel themselves during processes like cell movement, division, and molecular trafficking. Until now, it was commonly assumed ...

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

So, plant cells have a membrane, cytoplasm ... This episode breaks down the key facts about stem cells: what they are, how they differ in plants and animals, and why they're really useful for ...

The electronics weren’t hard, but custom membrane keypads are hard to come by. No matter, because it’s actually pretty easy to build your own. Membrane switches are usually made with ...

For instance, the nucleus stores genetic material, and mitochondria produce energy. Another essential part of a cell is the ...

The researchers were surprised to find that in Rhodospirillum two so-called porins – channel-like proteins that so-far were only known to be only responsible for the exchange of nutrients across the ...

Single-celled eukaryotes have a nucleus and may have other membrane-enclosed structures. Some scientists consider viruses to ...

The Brandeis Molecular and Cell Biology (MCB) Program offers a uniquely collaborative, nurturing, supportive and close-knit community conducting internationally recognized research at the frontiers of ...

Lipid bilayer forms a water-impermeable barrier that defines the boundary of a cell and of specialized compartments within a cell. Membrane proteins are embedded in lipid bilayers and serve a wide ...

A new approach to elucidate the operation and control of Polymer Electrolyte Membrane (PEM) fuel cells is being developed. A global reactor engineering approach is applied to PEM fuel cells to ...
