Membrane trafficking is the process by which proteins and other macromolecules are distributed throughout the cell, and released to or internalised from the extracellular space. Membrane ...

Himeoka and his team proposed a mathematical definition of cell death. It's based on the way cellular states, including metabolism, can be controlled by modulating the activities of enzymes. They ...

Dec. 2, 2024 — Eating a diet with a higher ratio of plant-based protein to animal-based protein may reduce the risk of cardiovascular disease (CVD) and coronary heart disease (CHD), according to ...

Cardiomyocytes consist of a complex membrane system that is subjected to high mechanical stress during heart muscle contractions. The so-called T-tubule network within the cells, which consists of ...

Membrane-bound organelles were the textbook standard of how scientists thought cells were organized until they realized in the mid-2000s that some organelles don’t need to be wrapped in a membrane.

Nov. 26, 2024 — Scientists have shed new light on how certain biological processes determine the development of neural cells. Their findings on a molecular 'bridge' complex demonstrate a new ...

Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA ...

Lucy Grealy was an unsparing observer of human physiognomy. She was a poet, with the requisite eye for piercing detail, but ...

A precancerous cell is a cell with certain abnormalities that makes it more likely to become cancerous. These abnormalities don't mean that it will become cancer—in fact, most don't—but the diagnosis ...

By this definition, bacteria, archaea and single-celled eukaryotes are microbes ... Perhaps this happened when a viruslike structure infected a collection of metabolic reactions enclosed within a ...

You probably learned about organelles, those little 'organs' inside cells that form compartments with individual functions. For example, mitochondria produce energy, lysosomes recycle waste and the ...
