  摘要：Humans lack memories for specific events from the first few years of life. We investigated the mechanistic basis of this infantile amnesia by scanning the brains of awake infants with functional magnetic resonance imaging while they performed a subsequent memory task. Greater activity in the hippocampus during the viewing of previously unseen photographs was related to later memory-based looking behavior beginning around 1 year of age, suggesting that the capacity to encode individual memories...

  摘要：Establishment of the apoplastic root barrier known as the Casparian strip occurs early in root development. In legumes, this area overlaps with nitrogen-fixing nodule formation, which raises the possibility that nodulation and barrier formation are connected. Nodules also contain Casparian strips, yet, in this case, their role is unknown. We established mutants with defective barriers in Lotus japonicus. This revealed that effective apoplastic blockage in the endodermis is important for root-t...

  摘要：On 3 October 2023, a multihazard cascade in the Sikkim Himalaya, India, was triggered by 14.7 million cubic meters of frozen lateral moraine collapsing into South Lhonak Lake. The impact generated an similar to 20-meter tsunami-like impact wave, which breached the moraine and drained similar to 50 million cubic meters of the lake's water. The ensuing glacial lake outburst flood (GLOF) eroded similar to 270 million cubic meters of sediment, which overwhelmed infrastructure, including hydropower...

  摘要：For applications of single-walled carbon nanotubes (SWNTs) in integrated circuits, it is crucial to have high-tube density arrays of SWNTs that are well aligned and purely semiconducting. In this work, we report on the direct growth of close-packed SWNT arrays on hexagonal boron nitride (hBN) substrates, demonstrating high alignment and uniform chirality within each array. Molecular dynamics simulations suggest that a self-assembly growth mechanism resulted from the intertube van der Waals att...
