Elon Musk took the stand on Wednesday in a trial brought by Twitter investors, who allege the billionaire committed securities fraud as he was buying the social media company in 2022. The class-action lawsuit alleges Musk agreed to buy Twitter but then waffled for months, attacking the company with the goal of bringing down the stock price to get a better bargain.
2月24日，浙江大学团队在《神经元》（Neuron）发表论文Endogenous retrovirus-derived RNA-DNA hybrids induce microglial synaptic pruning in autism models，报告他们发现内源性逆转录病毒（ERV，一类特殊的逆转座序列，在基因组中拥有大量序列相似的拷贝）衍生的RNA-DNA杂交体诱导自闭症模型中的小胶质细胞突触修剪。研究团队使用已被美国FDA批准用于治疗HIV感染的逆转录酶抑制剂进行早期干预，能够显著抑制ERV的逆转录活性，从源头上减少RNA-DNA杂交体的形成，进而降低补体分子的C4b表达、减轻小胶质细胞的过度修剪，最终挽救小鼠的自闭症核心症状。

Standard Public Domain Day fare.
