9、ournal of Stem Cells,suggest both parents contribute to the health status of their offspring a common sense conclusion which science is only now beginning to demonstrate,says the studys senior investigator,Joanna Kitlinska,PhD,an associate professor in biochemistry,and molecular and cellular biology
10、.“We know the nutritional,hormonal and psychological environment provided by the mother permanently influences organ structure,cellular response and gene expression in her offspring,”she says.“But our study shows the same thing to be true with fathers his lifestyle,and how old he is,can be reflected
11、 in molecules that control gene function,”she says.“In this way,a father can affect not only his immediate offspring,but future generations as well.”For example,a newborn can be diagnosed with fetal(胎儿的)alcohol spectrum disorder(FASD),even though the mother has never consumed alcohol,Kitlinska says.
12、“Up to 75 percent of children with FASD have biological fathers who are alcoholics,suggesting that preconceptual paternal alcohol consumption negatively impacts their offspring.”Advanced age of a father is correlated with elevated rates of certain diseases,and birth defects in his children.A limited

22、 to the gold.The voltage(电压)of the part of the machine that is placed in the light increases to the dark part and the electrons in the machine flow from high to low voltage.They are sent through an external circuit(外电路)creating a current that can be used to power another machine.The greater the cont

25、perhaps one day in the future we will be able to collect energy from them by placing the shadow-effect energy machine around the world in places that have been considered unfit for solar panels to work,or indoors.“A lot of people think that shadows are useless,”Tan says,but“anything can be useful,ev
