<jats:p>Outside consultants estimating planetary science mission costs for the next decade have produced huge numbers for the largest proposed missions, forcing some painful and unprecedented recommendations in the committee's report.</jats:p>

<jats:p> A military data set of civilian casualties, provided exclusively to <jats:italic>Science</jats:italic> , indicates that the war has become more lethal to the Afghan population, largely because of indiscriminate insurgent attacks. </jats:p>

<jats:p>The military is sending scientists onto the battlefield to find ways to improve emergency medicine, but the research faces a practical and ethical minefield.</jats:p>

<jats:p> We estimated the sensitivity of terrestrial ecosystem respiration to air temperature across 60 FLUXNET sites by minimizing the effect of seasonally confounding factors. Graf <jats:italic>et al</jats:italic> . now offer a theoretical perspective for an extension of our methodology. However, their critique does not change our main findings and, given the currently available observational techniques, may even impede a comparison across ecosystems. </jats:p>

<jats:p> Mahecha <jats:italic>et al</jats:italic> . (Reports, 13 August 2010, p. 838) estimated the temperature sensitivity of ecosystem respiration ( <jats:italic>Q</jats:italic> <jats:sub>10</jats:sub> ) and showed that temperature sensitivity and its site-to-site variability are lower than previously reported. We demonstrate that their <jats:italic>Q</jats:italic> <jats:sub>10</jats:sub> value of 1.4 is an underestimate if interpreted as the averaged sensitivities of all ecosystem components, because fast temperature fluctuations penetrate poorly into the soil. </jats:p>
