Impacts of inventory credit, input supply shops, and fertilizer microdosing in the drylands of Niger: [PDF]

open access: yes
"This study investigated the impacts of access to inventory credit, input supply shops, fertilizer microdosing demonstrations, and other factors on farmers' use of inorganic fertilizer and other inputs in Niger and on crop yields. We found that access to

Long‐Term Active Rather than Passive Restoration Promotes Soil Organic Carbon Accumulation by Alleviating Microbial Nitrogen Limitation in an Extremely Degraded Alpine Grassland

open access: yesAdvanced Science, EarlyView.
Active restoration increases soil organic carbon stocks by reducing microbial nitrogen limitation. Nitrogen availability promotes particulate to mineral‐associated organic carbon conversion by reducing microbial carbon use efficiency. Passive restoration has no effect on soil organic carbon stocks.

Incomplete markets and fertilizer use : evidence from Ethiopia [PDF]

open access: yes
While the economic returns to using chemical fertilizer in Africa can be large, application rates are low. This study explores whether this is due to missing and imperfect markets.

CD168 Identifies Proliferating Pancreatic Islet Cells in Murine and Human

open access: yesAdvanced Science, EarlyView.
This study identifies CD168 as a conserved surface marker for proliferating β‐cells in mouse, human islets, and pancreatic islet tumors. CD168⁺ cells show high proliferation and low insulin expression. CD168+ cells form mostly uni‐β lineage clones, and some of the clones are multi‐lineage.

Temporal Transcriptional Regulation of Human Neuronal Differentiation via Forward Programming

open access: yesAdvanced Science, EarlyView.
Single‐cell profiling of TF‐induced forward programming versus stepwise dual‐SMAD differentiation reveals that divergent trajectories set the pace of neurogenesis. OLIG TFs advance cell‐cycle exit via NOTCH modulation, while NEUROD2 later accelerates maturation. The study elucidates transcriptional mechanisms governing differentiation timing, providing

An Analysis of Fertilizer Policies in the Philippines [PDF]

open access: yes
The Philippines does not have a comparative advantage in the domestic production of fertilizer. This is one of the thoughts conveyed by the article as it analyzes the government policies affecting fertilizer prices during the post-war period, with a ...
