1. It's heaped with circuit boards, silicon chips and various electronic components that appear bizarre to laypeople.
2. Using digital silicon circuits inspired by neurobiology, the cognitive chips contain no biological elements.
3. Postdoctoral research associate Chang Kook Hong headed research using chicken feathers to make computer microchips that are twice as fast as silicon chips.
4. Unskilled workers heated circuit boards over coal fires to extract the minerals, or dipped silicon chips in acid baths to remove the protective coating.
5. Rogers'team uses a special etching method that slices chips off the surface of a bulk silicon wafer.
