A pancaked planet might not have any gravity. It’s unclear how gravity would work, or be created, in such a world, says James Davis, a geophysicist at Columbia University’s Lamont-Doherty Earth Observatory.

“Placing guards around tree pits allows urban trees to absorb more storm water runoff, taking pressure off the city sewer system,” said the study’s senior author, Patricia Culligan, a professor at Columbia Engineering and a member of Columbia’s Earth Institute and Data Science Institute.

Columbia University biomedical engineers have designed a new, biomaterials-based system that takes a soft approach to improving cell manufacturing and may bring new hope to cancer patients for T-cell therapy.

The study of life on and off Earth needs unified funding and a coherent plan, say Caleb Scharf, Director of Astrobiology at Columbia University, and his colleagues in a Nature article published January 8, 2018.

Using electron microscopy, Columbia University Medical Center biologists have captured the first detailed images of a calcium membrane pore in action, revealing a potential target for treating cancer.
