Mechanical pressure revealed as key factor in embryonic organ formation

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children's in Los Angeles has identified a mechanism by which embryonic cells organize themselves to send signals to surrounding cells, telling them where to go and what to do.

Cells' built-in stopwatch safeguards mitosis

Each day, hundreds of billions of cells in our body cycle through a period of growth and division. Yet in that time, only about 30 minutes is spent on the critical orchestration of mitosis, when chromosomes are carefully segregated from one parent cell to the next generation of two daughter cells.

Dartmouth research unlocks extended cell death pathway in aging brain cells

For oligodendrocytes-;the central nervous system cells critical for brain function-;age may not bring wisdom, but it does come with the power to cling to life for much, much longer than scientists knew.

Breakthrough tool illuminates neural stem cell dynamics

Researchers can use the light naturally thrown off by biological specimens to better study the different states of stem cells in the nervous system, thanks to a tool developed at the University of Wisconsin–Madison, brightening their chances for studying the way stem cells age.

New treatment paradigm focuses on reverting cancer cells to normal state

St. Jude Children's Research Hospital scientists reversed an aggressive cancer, reverting malignant cells towards a more normal state. Rhabdoid tumors are an aggressive cancer which is missing a key tumor suppressor protein.
