Breast cancer cells have vitamin D receptors, and when these receptors are activated by vitamin D, it triggers a series of molecular changes that can slow down cell growth, cause cells to die, and make the cancer less aggressive, she says.
This is not too surprising, since we are constantly moving forward in time, and what is considered modern painting or modern sculpture today, may not be seen as modern in fifty years time. Even so, it is traditional to say that Modern Art means works produced during the approximate period 1870-1970. This Modern era followed a long period of domination by Renaissance-inspired academic art, promoted by the network of European Academies of Fine Art. And is itself followed by Contemporary Art (1970 onwards), the more avant-garde of which is also called Postmodern Art.
Modern art includes artistic work produced during the period extending roughly from the 1860s to the 1970s, and denotes the style and philosophy of the art produced during that era. The term is usually associated with art in which the traditions of the past have been thrown aside in a spirit of experimentation.
