A long-term paddy rice distribution dataset in Asia at a 30 m spatial resolution.

Rice is a staple food for over half the global population and contributes to more than 10% of global anthropogenic methane emissions. Precise mapping of rice distribution in Asia, the primary region for rice cultivation responsible for over 60% of global production, is crucial for monitoring food security and greenhouse gas emissions. However, due to cloud cover impacts on optical remote sensing imagery, there is still a lack of long-term, high-resolution rice distribution datasets for the entire Asian region.

Resonant Forbidden CP Asymmetry from Soft Leptons.

To explain the baryon asymmetry in the early universe via leptogenesis, quantum corrections to new particles are commonly invoked to generate the necessary CP asymmetry. We demonstrate, however, that a large CP asymmetry can already arise from standard model leptons. The mechanism relies on resummation of soft leptons at finite temperatures.

Cordycepin mediates neuroprotection against apoptosis via ERK/CREB signaling activation in Aβ-induced neuronal cell models.

The aggregation of β-amyloid (Aβ) peptides has been associated with the onset of Alzheimer's disease (AD) by causing neurotoxicity due to oxidative stress and apoptosis. Cordycepin is a natural derivative of the nucleoside adenosine that displays potent antioxidant, antitumor, anti-inflammatory, and neuroprotective properties. However, the mechanism of the neuroprotective effect of cordycepin toward Aβ-induced neurotoxicity, as well as underlying mechanisms, is still unclear.
