Hidden Charge‐Order in the Mixed‐Valent K0.75Li2Cr6O12 High‐Pressure Oxide

open access: yesAdvanced Science, EarlyView.
K0.75Li2Cr6O12 is one of the few mixed valent chromium oxides. It shows a single angle spiral magnetic structure with a k = [1/3 1/3 ¼] propagation vector. Density functional theory reveals a hidden charge order that is necessary to stabilize the antiferromagnetic (AFM) ground state.

Youth Smoking in the U.S.: Prices and Policies [PDF]

open access: yes
After steadily declining over the previous 15 years, youth smoking began to rise precipitously in 1992, and by 1997 had risen by roughly one-third from its 1991 trough.

Sacrifice and Natality: Surrogacy Structures

open access: yesOpen Theology
In this article, I begin to unpick the complex relationships between birth and sacrifice, taking my cue from the strange surrogacy structures in the textual triptych Genesis 21-23 (the expulsion [“sacrifice”] of Ishmael and Hagar, the surrogate mother ...

SIRT5–RAC2 Axis Drives Monocyte‐to‐Macrophage Differentiation to Promote Inflammatory Injury in Premature Ovarian Insufficiency

open access: yesAdvanced Science, EarlyView.
SIRT5 desuccinylates and stabilizes RAC2, activating CSF1R‐dependent signaling to drive monocyte differentiation into M0 macrophages and their polarization toward pro‐inflammatory M1 phenotypes in CTX‐induced premature ovarian insufficiency. Inhibiting the SIRT5‐RAC2 axis attenuates inflammation, reduces granulosa cell apoptosis, and preserves ...

Immigrant-Native Fertility and Mortality Differentials in the United States [PDF]

open access: yes
Immigrants have been discussed as a means of alleviating fiscal pressures on Social Security. Their long-term impact on the Social Security system depends critically on their fertility and mortality patterns.

Natural Variations of ZmRLR1 Mediate the Root Lodging Resistance of Maize by Regulating Root Ascorbate and Auxin Homeostasis

open access: yesAdvanced Science, EarlyView.
Root lodging severely limits crop yield and quality. We reveal that ZmRLR1, a plasma membrane b‐type cytochrome, regulates lodging resistance in maize through dual roles: modulating intracellular redox balance and functioning as a novel component of clathrin‐mediated endocytosis to influence auxin homeostasis. Moreover, natural variations in the ZmRLR1

Endothelial PDGF Signaling Dysregulation Impairs Testicular Interstitial Homeostasis in Diabetes

open access: yesAdvanced Science, EarlyView.
Testicular endothelial cells (TECs) function as central signaling hubs that coordinate interstitial homeostasis. Diabetes disrupts TEC‐derived PDGF signaling, silences the JUND‐MCL1 survival program in Leydig cells, and impairs peritubular function, leading to fibrosis and testosterone insufficiency.
