    A stochastic multicellular model identifies biological watermarks from disorders in self-organized patterns of phyllotaxis

    Yassin Refahi et al
    A stochastic model of phyllotaxis can explain the striking irregularities observed in the spiral patterns of plants and predicts that perturbation patterns provide key information about the underlying biochemical mechanisms.

    Bottom-up and top-down influences at untrained conditions determine perceptual learning specificity and transfer

    Ying-Zi Xiong et al
    Perceptual learning is specific because of the absence of bottom-up stimulation and top-down modulation at the untrained conditions.

    N6-methyladenosine of HIV-1 RNA regulates viral infection and HIV-1 Gag protein expression

    Nagaraja Tirumuru et al
    Human proteins that add or remove the methyladenosine modification of cellular RNA, or recognize methylated RNA significantly affect HIV-1 infection or viral protein synthesis in cells, suggesting an important role for HIV-1 RNA methylation in regulating viral replication.
