Studying the process of brain formation illuminates just how much of development is a series of tiny miracles. Only a few weeks after a human egg is fertilized, a sheet of cells called the neural ...

Membrane potential creates the foundational electrical charge difference that allows human brain cells to function and send ...

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 ...

Doctors and scientists have long relied on microscopes to study human tissue and diagnose disease. But today's medical research produces far more information than the human eye alone can handle, ...

Scientists have often thought of cells as small, bustling cities with parts that resemble factories, power grids and shipping ...

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, ...
