In this incurable disease the regeneration of the epidermis is speeded up enormously: whereas it normally renews itself in just under four weeks, this period is cut to four to seven days in psoriasis patients. The reason is the greatly increased rate of cell division of the keratinocytes. The...APS announces the winners of its 2004 postdoctoral fellowship in physiological genomics

... rocks reveal an odd twist in the story - eventual regeneration of the greenhouse. Recall that 3 billion years ago, Earth was essentially Waterworld.
