A new nanomaterial could lead to novel types of displays.
Anne Wojcicki and Linda Avey, founders of the personal-genomics company 23andMe, talk about their goals for the company and the drive to personalize medicine.
This video combines different types of brain imaging to visualize a brain tumor in a female patient. Superimposed on a picture of the patient’s head are black and white images generated from traditional magnetic resonance imaging (MRI) presented sequentially in three different axes: side to side, front to back, and top to bottom. The tumor is then shown in yellow in the left hemisphere of the brain. Scientists further analyzed the data collected from the MRI to map the network of nerve fibers in the brain, seen here as red, green, and purple fibers. Neurosurgeons use these maps during surgery to remove the tumor to avoid damaging fiber tracts that are linked to important brain functions.
A tiny gripper that responds to chemical triggers could be a new tool for surgery.
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.
