This animation was generated from a normal human subject. It shows only the fibers that originate in a particular cross section of the brain. The blue arc in the middle of the brain is part of the cingulum bundle. Radiologists at Massachusetts General Hospital are beginning to use this method to examine their patients’ brain: it provides a quick way to scan through the entire set of data for abnormalities.
Researchers at Carnegie Mellon University have made a swallowable capsule robot that they can anchor to specific spots in the gut. In the center of the capsule robot rests a leg; the transparent polymer elastomer footpad is visible. The footpads are covered with oil-coated micropillars that stick to tissue without damaging it.
Gil Alterovitz, a research fellow at Harvard Medical School, translated populations of genes into musical notes. Each constellation (green) represents a key network of interrelated genes (blue). Each network is represented by a musical note. In healthy cells, the notes form music in harmony, indicating a healthy state. In cancer cells, the soundtrack veers out of harmony, signaling a transition from a healthy to a diseased state.
