Temperature and Farm Labor in Nigeria
ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

Three Dimensional Printing of Bioinspired Composite Aerogels for Solar Steam Generation
Freshwater scarcity demands efficient purification strategies. Inspired by desert grasses, reduced graphene oxide‐doped polyacrylamide aerogels with longitudinal grooves are fabricated via high‐speed three‐dimensional printing and freeze‐drying. The biomimetic design enables dual‐mode water transport, achieving a capillary flow of 2.16 cm in 10 minutes
