When embryonic cells get the signal to specialize the call can come quickly. Or it can arrive slowly. Now, new research from Rockefeller University suggests the speed at which a cell in an embryo receives that signal has an unexpected influence on that cell’s fate. Until now, only concentration of the chemical signals was thought to matter in determining if the cell would become, for example, muscle, skin, brain or bone.

Study: Heavy Bleeding Very Common As Women Approach Menopause
As women get older, their periods can begin to change. This perimenopausal time typically starts when a woman is in her 40s and lasts about four years. (The average age of menopause, when periods stop, is 51.) For some women, the transition means unpredictable, prolonged or heavy bleeding, and that can be frightening. Now new research shows that these changes may be quite normal.
