1. Decadal oscillations in the ocean's largest oxygen-deficient zone 

   Duprey N.N.; Foreman A.D.; Carriquiry J.D.; et al. (2024)

   Science

   The impact of global warming on the ocean's oxygen-deficient zones (ODZs) is uncertain, partly because of a lack of data on past changes. We report monthly resolved records of coral skeleton-bound nitrogen isotopes (CS-δ15N) to reconstruct denitrification in the Eastern Tropical North Pacific (ETNP) ODZ over the last 80 years. The data indicate strong decadal variation in ETNP denitrification, with maxima during the cool North Pacific ...

2. Quantum Cherenkov transition of finite-momentum Bose polarons 

   Seetharam K.; Shchadilova Y.; Grusdt F.; et al. (2024)

   Physical Review A

   We investigate the behavior of a finite-momentum impurity immersed in a weakly interacting three-dimensional Bose-Einstein condensate of ultracold atoms, giving a detailed account of the dynamical quantum Cherenkov transition discussed by K. Seetharam et al. [Phys. Rev. Lett. 127, 185302 (2021)0031-900710.1103/PhysRevLett.127.185302]. Using a time-dependent variational approach, we identify a transition in the far-from-equilibrium dynamics ...

3. Spectroscopic signatures and origin of hidden order in Ba<inf>2</inf>MgReO<inf>6</inf> 

   Soh J.R.; Merkel M.E.; Pourovskii L.V.; et al. (2024)

   Nature Communications

   Clarifying the underlying mechanisms that govern ordering transitions in condensed matter systems is crucial for comprehending emergent properties and phenomena. While transitions are often classified as electronically driven or lattice-driven, we present a departure from this conventional picture in the case of the double perovskite Ba2MgReO6. Leveraging resonant and non-resonant elastic x-ray scattering techniques, we unveil the ...

4. Seen and unseen vulnerabilities: Evaluating recovery from the 2015 Nepal earthquake to inform more equitable post-disaster needs assessments 

   Tan S.B.; McCaughey J.W.; Loos S.; et al. (2024)

   International Journal of Disaster Risk Reduction

   As disasters disproportionately impact socially vulnerable groups, it is critical to ensure that sufficient, timely, and appropriate disaster recovery aid and efforts are channeled towards such groups. Ensuring that disaster impact assessments accurately account for how different communities are affected by the studied events is thus essential, as these assessments often inform and shape subsequent disaster recovery programs. However, it ...

5. Image-guided optogenetic spatiotemporal tissue patterning using μPatternScope 

   Kumar S.; Beyer H.M.; Chen M.; et al. (2024)

   Nature Communications

   In the field of tissue engineering, achieving precise spatiotemporal control over engineered cells is critical for sculpting functional 2D cell cultures into intricate morphological shapes. In this study, we engineer light-responsive mammalian cells and target them with dynamic light patterns to realize 2D cell culture patterning control. To achieve this, we developed μPatternScope (μPS), a modular framework for software-controlled ...
