Cancer doesn’t evolve by pure chaos. Scientists have developed a powerful new method that reveals the hidden rules guiding how cancer cells gain and lose whole chromosomes—massive genetic shifts that ...

Researchers at Moffitt Cancer Center have developed a new way to predict how cancer cells evolve by gaining and losing whole chromosomes, changes that help tumors grow, adapt and resist treatment. In ...

Having extra chromosomes is typically an issue for an organism and can disrupt development or cause disease. But some cells benefit instead: For example, cancer cells or pathogenic yeasts can use ...

Scientists have long known that cancer cells typically have extra chromosomes, but what exactly was the extra genetic material doing? New research from a team at Yale University has finally provided ...

Basic biology has it that girls are girls because they have two X chromosomes — the things inside cells that carry our genes. Boys are boys because they have one X and one Y. Recently, though, there's ...

Women can be colorblind, but it’s much less common than in men. Red-green color blindness, the most common type, is inherited through the X chromosome. Since males have only one X, they need just one ...
