隐藏深海的热浪对珊瑚礁构成威胁

2019年四月至五月,位于南太平洋中部法属坡利尼西亚莫雷阿岛一带的珊瑚礁经历了长时间且严重的高温白化。由于该年并非厄尔尼诺年份,一般并不会出现这种情况,因此本事件令全球海洋科学界百思不解。

In CNS, such as retinal ganglion cells, IFNγ activates STAT1 in Ptpn2 cKO RGCs. STAT1 then upregulates neuronal cGAS expression. cGAS produces cGAMP and activate STING in neurons. In PNS, such as dorsal root ganglion, axotomy induces IFNγ expression in axons by local translation. And IFNγ activates STAT1-cGAS signaling and cGAMP production in surrounding Schwann cells and blood cells, to promote peripheral axon regeneration.

研究发现促进成年神经系统轴突再生的内在免疫机制

中枢神经系统一旦受创,例如在脊髓损伤的意外中,伤者很可能会永久丧失感觉或活动能力,当中的关键原因,是轴突断裂后无法再生。目前,医学界为脊髓损伤患者恢复活动能力的方法非常有限。若要为他们带来治疗希望,其中一个 研究方向,便是要破解令这些受伤轴突再生的方法。

科大研发纳米多孔锌电极 即弃碱性锌电池也可充电

香港科技大学(科大)的研究团队成功研制了一款新的电极设计,令日常生活中常见的非充电碱性锌电池变成可充电,有助推动更广泛使用充电池。

A joint research team from The Hong Kong University of Science and Technology (HKUST), and the LKS Faculty of Medicine, The University of Hong Kong (HKUMed) have demonstrated that ZCB11, a broadly neutralising antibody derived from a local mRNA-vaccinee against the spreading Omicron variants of SARS-CoV-2, displays potent antiviral activities against all variants of concern (VOCs), including the dominantly spreading Omicron BA.1, BA1.1 and BA.2. The research team members include (from left): Professor Dang
