5、rs of which he is the sole author, liburdy offered evidence that emfs increase the flow of calcium into lymphocytes, a kind of immune cell produced in the thymus. the papers created a stir, as calcium ions signal cells to turn genes on and off, and play a role in cell division. because tumor growth

7、to an unknown whistle-blower's allegations of scientific misconduct by liburdy, lbnl in january 1995 appointed a panel of four lab scientists to investigate. after reviewing raw data and interviewing liburdy and other scientists, the panel concluded in a july 1995 report that liburdy "delib

25、. yet improvements in energy efficiency mean dependence on oil is not what it once was. rich countries use less than half as much oil as they did in 1970 for each inflation-adjusted dollar of gdp. so although prices in real terms have returned to levels last seen in the 1970s, their impact is not as
