Social Amoeba Seek Kin Association – “Starving “social amoebae” called Dictyostelium discoideum seek the support of “kin” when they form multi-cellular organisms made up of dead stalks and living spores, said researchers from Baylor College of Medicine and Rice University in Houston in a report that appears online today in the open-access journal Public Library of Science Biology.”
Universal Mechanism Of Aging Found? – “Researchers have uncovered what may be a universal cause of aging, one that applies to both single cell organisms such as yeast and multicellular organisms, including mammals. This is the first time that such an evolutionarily conserved aging mechanism has been identified between such diverse organisms.”
