The Seasonality of Conflict

open access: yesConflict Management and Peace Science, 2020
This paper uses one of the largest changes to labor demand in developing countries—harvest—to examine how the returns to fighting vs. working impact the intensity of conflict. Exploiting the exogenous allocation and timing of harvest across Afghanistan, Iraq, and Pakistan, we find that the onset of harvest reduces the number of insurgent attacks by ...

Programmable 3D Photovoltaics via Mechanically Origami‐Coded Interlocked 3D Kirigami and Nano‐Root Anchored AgNWs–In–Ga Multiphasic Alloy Conductor

open access: yesAdvanced Materials, EarlyView.
Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

ENSO‐Driven Seasonal Variability in Near‐Surface Wind Speed and Wind Power Potential Across China

open access: yesGeophysical Research Letters
Seasonal variations in near‐surface wind speed (NSWS) significantly impact wind energy production, yet the role of the El Niño–Southern Oscillation (ENSO) in shaping these variations remains insufficiently explored.

High Humidity Exacerbates Psoriasiform Skin Disease Relapse by Increasing Tissue‐Resident Memory T Cells via Altering Skin Microbiota

open access: yesAdvanced Science, EarlyView.
We demonstrated that high humidity worsened psoriasis relapse in murine psoriasiform skin inflammation by increasing skin‐resident memory CD8+ cells via upregulating IL‐15Rα on keratinocytes. The increases in IL‐15Rα and memory CD8+ cells were attributed to S. nepalensis and its metabolite ADMA in skin exposed to high humidity.

Seasonal Changes in Fish eDNA Signal Vary Between Contrasting River Types

open access: yesEnvironmental DNA
Due to the societal reliance on goods and services provided by river systems and their close proximity to settlements, few modern‐day rivers are without significant anthropogenic modifications.

Climate Change Threatens Micronutrient Density of European Winter Wheat

open access: yesAdvanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Invasive Aquatic Plants as Ecosystem Engineers in an Oligo-Mesotrophic Shallow Lake

open access: yesFrontiers in Plant Science, 2018
Exotic hydrophytes are often considered as aquatic weeds, especially when forming dense mats on an originally poorly colonized environment. While management efforts and research are focused on the control and on the impacts of aquatic weeds on ...
