From rocks to icebergs, the natural world tends to break into cubes
Douglas Jerolmack of the School of Arts & Sciences commented on his research, which finds that when natural structures break apart, they tend to fragment into cube-like shapes. He said the findings could help geologists calculate the size of rocks breaking off cliff faces, among other applications.

A squid’s eye view
Alison Sweeney of the School of Arts and Sciences discussed the complex structure of squids’ eyes, which have special lenses that allow for crisp vision in dark water. “The resolution of their eyes is approaching that of humans, their retinas are much more sensitive than ours are to light, and if you dig into the nitty-gritty of how nature figured it out, I’m forever blown away at the level of nuance to get it to work.”
