Cells contain various specialized structures—such as the nucleus, mitochondria or peroxisomes—known as "organelles." Tracing their genesis and determining their structure is fundamental to ...

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane ...

Biology textbooks may need a revision, say scientists, who present new evidence that an arm-like structure of mammalian brain cells may be a different shape than scientists have assumed for more than ...

Ultraviolet (UV) radiation is known to cause DNA damage, and while that damage may accumulate and eventually lead to diseases like skin cancer, cells also have repair mechanisms that can fix ...
