...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...
...tiles he ships each week.Smuts’s work inherently deals with the picture elements of everyday life, from the pixels of a computer screen to the square blocks of a city’s layout. Painting itself relies on pixelization in the suspended dots of insoluble pigment that give each color its hue. Indeed, the rods and cones of our eyes actually pixelize our view of reality, though with very fine resolution.Artists have long turned to pixels as a medium, from the stunning Roman, Byzantine and early Christian mosaics (think of “Alexander at Issus...
...alkali. So when you spill red wine on the carpet, you mop up as much as you can, then sprinkle on bicarb soda. The alkali negates the acid. You'll see straight away the stain change from red to pale gray as the pH swaps over and the pigment starts to break down and the wine loses its staining ability." Lush hopes the book will help others see cleaning crises the way she does: as puzzles. "It's basic chemistry," she says. "The building blocks of everything around you are pretty simple. You just need to look at things...
