Cell Polarity and Chirality: Human endothelial cells on a micropatterned ring (inner diameter: 250 mm, width: 200 mm) stained for actin (red), tubulin (green), and nuclei (blue). Cells form a ‘rightward’ chiral alignment, while polarized by positioning their centrosomes (bright green) rather than cell nuclei closer to each boundary.

A team of researchers led by Gordana Vunjak-Novakovic has developed a new technique to evaluate human stem cells using cell micropatt

When neurobiologist Tom Jessell joined Columbia University Medical Center 25 years ago it was, he said, to interact with cutting edge scientists and “join the

Rafael Yuste likens scientific research to mountain climbing. Assemble a skilled team, get the best equipment, map the route and proceed with slow, deliberate steps.

Not every child can dream up a smartphone application and see it come to life. But that’s what happened when 8-year-old William Belhumeur suggested his father make an app that identifies plants using visual recognition technology.

If we think of the atmosphere as a sponge, we can imagine that the sponge is very dry in the western US, and almost full over humid regions in the eastern US. The addition of moisture to the atmosphere from the land surface in these humid regions makes the sponge leak (makes rain fall). In the west, the dry sponge soaks up any moisture the land surface can contribute without initiating rainfall: rainfall in the west is only initiated by other mechanisms. Credit: Kirsten Findell, NOAA/GFDL
A team of researchers from Columbia Engineering, Geophysical Fluid Dynamics Laboratory, and Rutgers University has now demonstrated that evaporation from the land surface is able to modify summertime rainfall east of the Mississippi and in the monsoonal region in the southern U.S.
