MTI graduate student Yushiro Okamoto explains the idea behind IceWall, which he and fellow architecture graduate student Kian Hiu-Lan Yam designed as part of the MIT150 Festival of Art, Science, and Technology.
Over roughly nine days, a ball of mouse embryonic stem cells (gray) gives rise to a cup-shaped structure (green) with a complex three-dimensional architecture identical to the retina in early development. A tiny sac of cells balloons outward from the clump's surface; then the sac folds in on itself, with retinal pigment cells on the outside and retinal neurons on the inside.

In this video, a mouse with a fiberoptic cable implanted into his brain explores a four-arm maze. The animal has been genetically engineered to express light-sensitive proteins in a specific part of the amygdala, a brain region linked to fear. Mice are naturally afraid of open spaces, and at the beginning of the video, the mouse spends most of his time in one corner of the maze, occasionally dashing out to explore his environment. Turning on the light (as indicated by blue text) activates a specific neural circuit, which appears to make the mouse much braver, continually exploring all the parts of the maze. The video is shown at ten times normal speed.
The two upper panels of this video show different views of a cell while the lower left shows the presence of bubbles, called vesicles, within it. On the lower right, the thin petals can be see in cross-section as they form, ripple over the cell, and subside. Built from 40,000 images, this video provides scientists with an unprecedented amount of visual information.
