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 prokaryotes, ...
The white blood cells in question are cytotoxic T lymphocytes (CTLs), also known as killer T cells. These "warrior" cells ...
Think back to that basic biology class you took in high school. You probably learned about organelles, those little “organs” inside cells that form compartments with individual functions. For example, ...
A microscope picture of human bone cells (U2OS) showing the localization of a lipid (phosphatidylethanolamine). The lipid is visible in orange, the cell membrane in purple, and endosomes in white. New ...
Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...
Our bodies are made up of countless cells, and each one is enclosed by a thin layer called the cell membrane. This membrane ...
New technique to image single lipids: Lipids are notoriously difficult to detect with light microscopy. Using a new chemical labeling strategy, the Dresden team has overcome this limitation, enabling ...
Hemifusomes are fused vesicles, or sacs of fluid, that were previously unknown to exist inside cells. They were discovered using cryo-electron tomography, which literally freezes them in time, and ...

Cancer cells' stress shield cracked by compound that binds in one place, inhibits in another
Cancer cells are pretty bold and clever—they hijack cellular survival and healing processes in order to fuel their growth, ...
Photons of light possess linear and angular momentum. This fundamental characteristic is crucial to trapping objects optically using a highly focused laser beam. Using this light feature, the Optical ...
