Edited by Arun Agrawal, University of Michigan, Ann Arbor, MI, and approved February 5, 2021 (received for review June 24, 2020)This study examines evidence of the health benefits of natural soundscapes and quantifies the prevalence of restorative acoustic environments in national parks across the United States. The results affirm that natural sounds improve health, increase positive affect, and lower stress and annoyance. Also, analyses reveal many national park sites with a high abundance of natural sound and low anthropogenic sound. Raising awareness of natural soundscapes at national...…Edited by Arun Agrawal, University of Michigan, Ann Arbor, MI, and approved February 5, 2021 (received for review June 24, 2020)This study examines evidence of the health benefits of natural soundscapes and quantifies the prevalence of restorative acoustic environments in national parks across the United States.

Edited by Boris I. Shraiman, University of California, Santa Barbara, CA, and approved January 29, 2021 (received for review September 19, 2020)Fluid flow plays an important role during oogenesis. From insects to mice, oocytes mature by acquiring cytoplasm from sister germ cells, yet the biological and physical mechanisms underlying this transport process remain poorly understood. To study the dynamics of “nurse cell dumping” in fruit flies, we combined direct imaging with flow-network modeling and found that the intercellular pattern and time scale of transport are in accordance with a...…Edited by Boris I.
