  1. Mollusk shells could measure water temperature of modern and ancient oceans Pupa Gilbert, University of Wisconsin-Madison, DMR 1105167 The iridescent inner lining of certain mollusk shells could be used as a thermometer: it retains in its structure a permanent record of the temperature of the water in which it was formed. This was only a first-discovery experiment, and much more validation is necessary before we can establish mollusk shell nacre structure as a “proxy” to measure the temperatures of ancient oceans. If validated, however, this could be a very valuable proxy, because nacre goes back 450 million years. IC Olson, R Kozdon, JW Valley, PUPA Gilbert. JACS 134, 7351-7358, 2012.

  2. Mollusk shells could measure water temperature of modern and ancient oceans Pupa Gilbert, University of Wisconsin-Madison, DMR 1105167 In this photo PI Gilbert teaches a 2-week class on “The physics of additive and subtractive color mixing” to under-represented minority high school students. Each student is using a spectrophotometer to analyze the results of their paint mixtures. This set of classes is part of the PEOPLE program at UW-Madison. PEOPLE gives a fellowship for the entire college period to students that have attended summer classes for 4 years during high school. Attending the PEOPLE program does not guarantee admission at UW, but it has greatly increased minority enrollment at UW. In 2011 alone, 180 incoming students were offered PEOPLE fellowships, 100 accepted and are currently enrolled and fully supported. This program has been successful for several years, and it can only work because of the voluntary participation of UW faculty, such as Gilbert.
