Cell growth and division are two of the most fundamental and essential features of life, and closely monitoring cell changes over time can give scientists key insights into dynamics of these ...

For decades, biology textbooks have taught that human hair grows because new cells in the hair root divide and push older ...

Our results reveal a fascinating choreography inside the hair follicle," said paper author professor Inês Sequeira.

Researchers have captured time-lapse videos of stem cells dividing in growing plant roots. By watching how the cells divide in response to certain chemical signals over time, the team is uncovering ...

Imagine tuning into a football game, but all of the players are invisible except for the two quarterbacks. Without being able to see the orchestrated movements of the full teams, this would be a very ...

Transmission electron microscopy reveals the architecture of cells at nanometer resolution, but chemical fixation severely warps their native structure. The true ultrastructure of cells can be ...

Scientists have found that human hair growth does not grow by being pushed out of the root; it's actually pulled upward by a ...

Scientists have captured a never-before-seen, high-resolution look at influenza’s stealthy invasion of human cells, revealing ...

Some time before 1668, Antony van Leeuwenhoek learned to grind lenses and make simple microscopes. Scientists have been looking through different versions of this imaging system ever since. There’s ...
