Berkeley Lab Researchers Discover a Rotational Motion of Cells that Plays a Critical Role in Their Normal Development

In a study that holds major implications for breast cancer research as well as basic cell biology, scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, which the researchers call “CAMo,” for coherent angular motion, is necessary for the cells to form spheres. Without CAMo, the cells do not form spheres, which can lead to random motion, loss of structure and malignancy.

”What is most exciting to me about this stunning discovery is that it may finally give us a handle by which to discover the physical laws of cellular motion as they apply to biology,” says Mina Bissell, a leading authority on breast cancer and Distinguished Scientist with Berkeley Lab’s Life Sciences Division.

River Mystery Solved

*Scientists discover how “Didymo” algae bloom in pristine waters with few nutrients*

The pristine state of unpolluted waterways may be their downfall, according to research results published in a paper this week in the journal Geophysical Research Letters.

A species of freshwater algae that lives in streams and rivers, called Didymo for Didymosphenia geminata, is able to colonize and dominate the bottoms of some of the world’s cleanest waterways–precisely because they are so clear. (more…)
