In most donors , the electron binding energy and , therefore , the electron concentration , does not change appreciably with a change in the material 's bandgap . Notwithstanding this , Science Magazine , an ESC research booster , later published a paper by Stanford University pathologist Irving Weissman insisting that in a rodent study an infusion of marrow stem cells " did not contribute appreciably to [ such tissues ] as brain , kidney , gut , liver , and muscle . Many watersheds contain acreage that does not contribute appreciably to runoff of P , and most of the annual P loss occurs during a few high-runoff events . Since the answer is one of probability , that is to say that not all such studies will contribute appreciably , only some will , and since we cannot very well predict which ones will pay off , it is best to have a healthy number of scientific research programs going on , knowing that some will have great benefit .
