For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

A new study by researchers from Drexel University College of Medicine reverses the popular scientific dogma that the protein tau stabilizes microtubules within brain cells. The scientists’ new ...

Cellular life hinges on a network of hollow cables called microtubules dynamically lengthening and shortening according to the needs of the moment. During cell division, for instance, these cables ...

A structural protein best known for building the internal scaffolding of cells may double as a natural defense against the ...

Though it is widely believed that tau protein stabilizes microtubules in neurons of the brain, new research suggests just the opposite: tau lengthens microtubules and keeps them dynamic. A new study ...

Actually, I had no idea in the early 1960s that I was entering the arena of microtubule research, because it hadn't yet been defined as an arena. Although the term 'microtubule' was first coined in ...

As organisms grow, live, and move through the world, they're subjected to an array of internal and external forces. Biological forms must be able to withstand the stresses of stretching and ...

The chromosomes, once they have duplicated genetic information, move to the center of the cell and the cell, in a very remarkable way, quickly sprouts from its two ends large tubes that hook the ...
