HHMI researchers suggest that defective cell transport may play a role in Alzheimer’s disease. Over the last few years, scientists have been successful in identifying genes implicated in Alzheimer’s ...

Ron Kaback didn’t believe that electrochemical gradients could power the transport of sugars and amino acids across cell membranes—until he proved that they do. The measles virus attacks long-lived ...

Transport of molecules within a cell and out of the cell requires a complex endomembrane system. Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell ...

Siegfried Musser, PhD, and his team in the Department of Cell Biology and Genetics at the Texas A&M College of Medicine have ...

In pure water, the cell contents (the cytoplasm and vacuole) push against the cell wall and the cell becomes turgid . Fully turgid cells support the stems of non-woody plants. In a very ...

Most of us rely heavily on shipping services like FedEx or UPS to ensure we receive the correct packages. If that system was ...

Researchers from the Chair of Optics and Photonics of Condensed Matter led by Prof. Dr. Carsten Deibel at the Chemnitz ...

The circulatory system transports substances between the exchange surface and cells. It delivers oxygen and glucose to the tissues for respiration, which is the release of energy to cells.

The ability to maintain concentration gradients and sometimes move materials against them is vital to cell health and maintenance. Thanks to membrane barriers and transport proteins, the cell can ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex organisms, such as animals and plants.
