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 ...
Developing reliable methods to replace dead or damaged tissue is one of the primary goals of regenerative medicine. With ...
In a new Nature Communications study, scientists have developed a novel method for artificial cells to interact with their ...
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 ...
their surface area — and thus their ability to both take in nutrients and transport electrons — does not increase to the same degree as their volume. As a result, prokaryotic cells tend to be ...
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 ...
