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.

SLC6A14 Drives Mitochondrial Fusion and Oxidative Phosphorylation to Promote Cancer Stemness and Early‐Onset of Breast Cancer

open access: yesAdvanced Science, EarlyView.
Elevated levels of the plasticizer DEHP associate with earlier breast cancer diagnosis. DEHP enhances glutamine‐powered energy production via the transporter SLC6A14 and pushes mitochondria toward fusion, driving tumor initiation by boosting cancer stemness. Blocking SLC6A14 lowers stemness, slows tumors, and improves chemotherapy response.
