Cells cannot remain alive outside certain limits of temperature, and much narrower limits mark the boundaries of effective functioning. Enzyme systems of mammals and birds are most efficient only within a narrow 1 around 37℃; a 2 , of a few degrees from this value seriously impairs their functioning. Even though cells can survive wider 3 , the integrated actions of bodily systems are impaired. Other animals have a wider tolerance 4 changes of body temperature. For centuries 5 has been recognized that mammals and birds differ from other animals in the way they regulate body temperature. Ways of 6 the difference have become more accurate and meaningful over time, but popular terminology still reflects the old division 7 "warm blooded" and "cold blooded" species; warm blooded included mammals and birds, 8 all other creatures were considered cold blooded. 9 more species were studied, it became evident that this classification was 10 . A fence lizard usually has a body temperature only a degree or two below 11 of humans and so is not cold. 12 the next distinction was made between animals that maintain a 13 body temperature and those whose body temperature varies with their environment. But this classification also proved inadequate, 14 among mammals there are many that vary their body temperatures during hibernation. 15 many invertebrates that live in the 16 of the ocean never experience a change in the chill of the deep water, and their body temperatures remain constant. The current distinction is between animals whose body temperature is 17 chiefly by internal metabolic processes and those whose temperature is regulated by the 18 The latter do so mainly by moving to favorable sites or by changing their exposure to 19 sources of heat. Mammals and birds also regulate their temperature by choosing favorable environments, but primarily they regulate their temperature by making a variety of internal 20 .

The journal em>Science/em> is adding an extra round of statistical checks to its peer-review process, editor-in-chief Marcia McNutt announced today. The policy follows similar efforts from other journals, after widespread concern that basic mistakes in data analysis are contributing to the irreproducibility of many published research findings. "Readers must have confidence in the conclusions published in our journal," writes McNutt in an editorial. Working with the American Statistical Association, the journal has appointed seven experts to a Statistics Board of Reviewing Editors (SBoRE). Manuscript will be flagged up for additional scrutiny by the journal's internal editors, or by its existing Board of Reviewing Editors or by outside peer reviewers. The SBoRE panel will then find external statisticians to review these manuscripts. Asked whether any particular papers had impelled the change, McNutt said. "The creation of the 'statistics board' was motivated by concerns broadly with the application of statistics and data analysis in scientific research and is part of em>Science/em>'s overall drive to increase reproducibility in the research we publish." Giovanni Parmigiani, a biostatistician at the Harvard School of Public Health, a member of the SBoRE group. He says he expects the board to "play primarily an advisory role." He agreed to join because he "found the foresight behind the establishment of the SBoRE to be novel, unique and likely to have a lasting impact. This impact will not only be through the publications in em>Science/em> itself, but hopefully through a larger group of publishing places that may want to model their approach after em>Science/em>." John Ioannidis, a physician who studies research methodology, says that the policy is "a most welcome step forward" and "long overdue." "Most journals are weak in statistical review, and this damages the quality of what they publish. I think that, for the majority of scientific papers nowadays, statistical review is more essential than expert review," he says. But he noted that biomedical journals such as em>Annals of Internal Medicine, the Journal of the American Medical Association/em> and em>The Lancet/em> pay strong attention to statistical review. Professional scientists are expected to know how to analyze data, but statistical errors are alarmingly common in published research, according to David Vaux, a cell biologist. Researchers should improve their standards, he wrote in 2012, but journals should also take a tougher line, "engaging reviewers who are statistically literate and editors who can verify the process." Vaux says that em>Science/em>'s idea to pass some papers to statisticians "has some merit, but a weakness is that it relies on the board of reviewing editors to identify 'the papers that need scrutiny' in the first place." It can be learned from Paragraph 1 that ______.
