Stoichiometric regulation of nitrogen and carbon fluxes in Acropora coral facing short‐term stress of ammonium loading

open access: yesEcosphere
Scleractinian coral evolved under nitrogen (N)‐limited conditions. The increase in N flux from anthropogenic activities to these otherwise N‐depleted environments is threatening coral health and coral reef ecosystem function.

Tailoring Successive Magnetic‐Dielectric Synergy for Enhancing Electromagnetic Absorption in Ultralong Heterostructure Chains Assisted by High Static Magnetic Field

open access: yesAdvanced Science, EarlyView.
This work proposes a high static magnetic field (HSMF) driven dual‐low‐dimension strategy for fabricating magnetic‐dielectric heterostructure (Fe3O4@MoS2) chains with programmable lengths. The constructed successive magnetic‐dielectric synergy, arising from uniaxial anisotropy‐enhanced magnetic response and abundant heterointerfaces that boost ...

Bionic Solar‐Powered Heavy Metal Trap for Eco‐Friendly Sludge Drying and Simultaneous Electricity Generation

open access: yesAdvanced Science, EarlyView.
Herein, we propose a solar‐powered heavy metal trap (SPHT) for sludge disposal. The indoor experiments demonstrated that the sludge water content decreased from 90 % to 31 %, coupled with a decrease in heavy metal content to 6 % at most. Furthermore, the designed SPHT generated an initial potential of 0.10 V, and monitoring this hydrovoltaic potential ...

SERRATE Regulates Floral Meristem Activity by Antagonizing SHOOT MERISTEMLESS and Repressing Cytokinin Signaling

open access: yesAdvanced Science, EarlyView.
Floral meristem (FM) activity is crucial for the initiation of floral organs. In this study, SE represses IPT7 expression and cytokinin signaling via both the miR171c‐5p–KNAT2 and miR164c–CUC1/2–KNAT2 regulatory modules, thereby repressing FM activity. In contrast, STM induces both KNAT2 and IPT7 expression.

New radiocarbon dates from the Bapot-1 site in Saipan and Neolithic dispersal by stratified diffusion [PDF]

open access: yes, 2010
The colonisation of the Mariana Islands in Western Micronesia is likely to represent an early ocean dispersal of more than 2000 km. Establishing the date of human arrival in the archipelago is important for modelling Neolithic expansion in Island ...
