<jats:p>Upriver habitats—including a critical refuge created when construction began on the Three Gorges Dam—are now at risk from a series of new projects.</jats:p>

<jats:p>Newly published studies present the strongest evidence yet for a link between the 2008 Wenchuan earthquake and the reservoir behind the 156-meter-high Zipingpu Dam.</jats:p>

<jats:p>Research presented at the ACS meeting suggests that packing RNA strands together to form nano-sized particles could help get them into target cells and that another nanoparticle may lead to novel kinds of vaccines.</jats:p>

<jats:p>At the ACS meeting, a pair of research groups reported that they now have synthetic nucleotides that can be incorporated into DNA and can be copied with near perfection by enzymes that copy natural DNA.</jats:p>

<jats:p>The first citywide air quality study of its kind, reported at the meeting, suggests that unless more than 26% of cars switch to biofuels, it will have negligible effect on air pollution.</jats:p>

<jats:p> Ilonidis <jats:italic>et al</jats:italic> . (Reports, 19 August 2011, p. 993) report acoustic travel-time decreases associated with emerging sunspot regions before their appearance on the solar surface. An independent analysis using helioseismic holography does not confirm these travel-time anomalies for the four regions illustrated by Ilonidis <jats:italic>et al</jats:italic> . This negative finding is consistent with expectations based on current emerging flux models. </jats:p>

<jats:p>Braun claims that his analysis using helioseismic holography does not confirm the detection of emerging sunspot regions. We examine his measurement procedure and explain why his method has different sensitivity than our method. We also discuss possible physical processes that may cause the detected phase travel-time shifts.</jats:p>
