Promise For The Future Cholesterol Crystals In Color Thermometer
Westinghouse researchers describe liquid crystal films derived from cholesterol that change color with tiny temperature shifts on skin or tissue. The color changes may reveal blood flow, drug effects, and arterial constriction areas, with potential medical and industrial uses.
On This Day 1964 Highlights and Science Reflections
The history notes recount Rutherford Hayes election by a special commission after the 1876 electoral dispute and Jefferson Davis’ 1889 death. It also mentions Coolidge’s 1923 radio address and 1938 Nazi France pact, plus 1941 FDR plea to Hirohito. The piece shifts to cholesterol as a liquid crystal, noting corkscrew alignment and color changes with temperature and reactions and quotes from Dr. W E Shoupp and J L Ferguson on implications for biology and future research.
