A | The father of the Highland Park shooter will be criminally investigated, according to The Guardian, for signing off on his son’s firearm license in 2019. On July 4, 2022, his son allegedly murdered seven people and injured at least 40 more.,Robert Crimo Jr., the father of Robert Crimo III, sponsored his son’s firearm license in 2019. In Illinois, gun purchasers must be at least 21 years of age if they do not have the written consent of their parent or legal guardian. Crimo Jr. admitted to signing the affidavit to media outlets before the criminal investigation became public. By signing the document, he agreed to be held liable “for any damages resulting from the minor applicant’s use of firearms or firearm ammunition.”,Crimo Jr. signed the application despite his son having two previous encounters with the police. One of those encounters occurred in September 2019, during which Crimo III allegedly stated that he would “kill everybody” in his family. Law enforcement confiscated 16 knives, a dagger, and a sword from Crimo III’s room that day, but they were returned after Crimo Jr. claimed that the weapons were his and were only stored in his son’s room for “safekeeping.”,When asked if he regretted the decision to sign off on his son’s firearm purchase, Crimo Jr. said he does not. “Had I purchased guns throughout the years and given them to him in my name, that’s a different story. But he went through that whole process himself.” Crimo Jr. also noted that his son purchased firearms himself before the shooting.,Crimo III is currently 22 years old and would not have needed to get his parents’ permission for a firearm license if he applied for one after his 21st birthday.,Crimo Jr. says his son had “good morals” and that the two had talked about the Copenhagen, Denmark, shooting that took place a day earlier. During that conversation, Crimo Jr. says that his son called the Denmark shooter “an idiot.”,Police say that Crimo III told them he had planned another massacre at a Wisconsin Fourth of July parade after he left Highland Park. He instead decided to return to Illinois where he was arrested driving his mother’s vehicle.,This is not the first time the parents of an alleged mass shooter have found themselves in legal trouble. Two parents in Michigan were charged with involuntary manslaughter after their 15-year-old son used a gun they purchased to murder four classmates.,There were 13 mass shootings nationwide over the Fourth of July weekend.。夜空中的银河看似一张扁平、光滑的旋转圆盘，但实际上，这张“圆盘”并没有看上去那么简单。中国科学院紫金山天文台科研团队在银河系分子气体外盘中首次发现广泛分布的波纹状褶皱结构。这一发现为理解银河系三维结构及其动力学演化提供了新的关键观测证据。相关研究成果8月7日发表在国际期刊《自然·天文学》上。银河系的整体形状像一块受热变形的唱片，一侧向上翘起、另一侧向下弯曲。科学家把银河系的这种大尺度形变称为“翘曲结构”。然而，银河系中更细尺度的垂直结构是怎样的，长期缺乏系统性的观测与定量研究。

B | 科研团队借助紫金山天文台建立在青海省海西蒙古族藏族自治州的13.7米毫米波望远镜“银河画卷”一氧化碳巡天数据，证认出3万余个外盘分子云。“我们对3万多个分子云进行了三维分析。”论文第一作者兼共同通讯作者、中国科学院紫金山天文台副研究员孙燕介绍，一氧化碳是追踪冷分子气体的重要“示踪剂”，而分子气体正是恒星形成的原料。研究团队首先定量构建了银河系一氧化碳外盘的翘曲模型，拟合扣除大尺度翘曲背景后，发现背景结构中呈现清晰的波纹状垂直起伏，这些起伏被称为“褶皱”。 “褶皱表现为大片盘面整体向上或向下偏离，它们可能来自外部引力扰动激发的‘弯曲波’。”孙燕认为，“这很有可能是矮星系等卫星星系从银河系附近飞掠时，其引力对银河系产生了扰动，于是在银河系外盘中激起缓慢传播的‘涟漪’。”（记者金凤张添福）。
