“制造”超新星

新发现 2021年第8期 44-49页

作者： benoît rey 王佳蕾不详

半世纪的努力换来了一秒钟的影像。这短暂的一秒改变了巨星的命运。在这一瞬间,恒星核心忽然坍缩,随之产生的一股骇人冲击波炸开了整个恒星,并将其物质抛撒至太空一这就是超新星,堪称宇宙中最剧烈的爆炸。

追捕中等质量黑洞

新发现 2021年第9期 42-46页

作者： benoît rey 陈天涵(编译) 不详

在强大观测技术的帮助下,中等质量黑洞终于现身了。而天文学家对它们的大追捕才刚刚开始!潜伏在阴影中,隐蔽在星系最黑暗的角落,甚至躲过了人类望远镜的层层巡视:难以捕捉的中等质量黑洞是科学家最不了解的一类黑洞。

Aicardi-Goutieres syndrome(AGS)is a systemic inflammatory disorder caused by mutations in any one of the nine different genes,whose deficiency provokes a type I(interferon)IFN response probably central to pathogenesis.^(1) ADAR1,one of the genes mutated in AGS(AGS6),encodes for an enzyme that belongs to the ADAR family(ADAR1,ADAR2,and ADAR3)that catalyzes the conversion of adenosine to inosine within double-stranded RNAs(dsRNAs)(RNA editing A-to-1).
