Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...
How do biological cells join forces to form a structure? In her Ph.D. research, Daphne Nesenberend uses mathematics to show how forces and cooperation between cells create structure—and how ...
The story of the princess and the pea evokes an image of a highly sensitive royal young woman so refined, she can sense a pea under a stack of mattresses. When it comes to human biology, it also takes ...
Cells in the body have to move around in order to do their jobs. During development, for instance, cells are distributed to create and grow tissue. And in the event of an immune response, different ...
All cells need to sense and respond to their environment—to know when to activate genes, build proteins and carry out their basic functions. One of the most well-studied cellular responses is how they ...
Two American biologists have won this year's Nobel Prize in Physiology or Medicine for discovering a crucial way genes are regulated. Two American biologists have won this year's Nobel Prize in ...
The average human cell contains roughly 10,000 different proteins. Existing as several to millions of copies in each cell, proteins mediate all manner of tasks, including chemical transformations, ...
Researchers have uncovered how different types of brain cells work together to form large-scale functional networks in the human brain -- interconnected systems that support everything from sensory ...
The 2024 Nobel Prize in physiology or medicine has been awarded to US scientists Victor Ambros and Gary Ruvkun for their work on the discovery of microRNA, a molecule that governs how cells in the ...
