...Using scanning electron microscopy, Raman spectroscopy, and a slew of other state-of-the-art techniques, scholars at the Harvard University Art Museums found materials in the paintings that were not available until years after Pollock died. The analysis revealed that one of the three paintings includes a brown pigment that was not created until the early 1980s and not available on the market until 1986. Pollock died in 1956. The other two paintings spawned similar findings, containing materials not available before 1962 or 1963, according to the study. Despite the growing controversy, Boston College’s McMullen Museum...
Ella has learned from her research that the blue color in her dream is that of the precious lapis lazuli pigment used in Renaissance paintings to emphasize the Virgin’s miraculous agency. And as the color recurs throughout Chevalier’s novel, it becomes a motif for Isabella’s and Ella’s own searches for agency...
...Change the Definition. Make it poverty, not pigment. This is an imperfect solution. Yes, a disproportionate number of African Americans and Latinos are poor, but the majority of poor people are white-and more than a few are Asian. If race-based remedies are supplanted by class-based remedies, the number of African Americans attending elite universities, for one thing, will fall. Tom Kane, a Harvard economist, told me, "You'd need an economic affirmative-action program six times the size of the current racial preferences to [benefit] an equivalent number of African Americans." There's another step that would...
...five weeks the thale-cress will have sprouted and turned red if it encounters nitrogen dioxide. Normally, plants neutralize nitrogen dioxide, which they recognize as harmful. But Aresa scientists, led by founder Meier, have genetically engineered thale-cress, fusing its nitrogen dioxide neutralizer with an enzyme that creates red pigment (plants naturally produce red pigment, which isn't visible until the green disappears in autumn...
...Director of the Wellman Center for Photomedicine at MGH, was instrumental in the development and testing of a newly invented tattoo ink that is fully removable and completely safe. “The tattoo consists of these little submicron particles that are designed so that they carry the pigment permanently, but can be cracked open and then the pigment is released,” Anderson explained. Unlike the ink currently used to make tattoos, Anderson said the new ink is the first that was specifically designed for tattoos and is made from safe, Food and Drug Administration-approved materials. Until...
