立春刚过，但在东北似乎还没有感受到春的脚步。这两天，哈尔滨的最低气温依然在零下20摄氏度左 右。严寒没能阻挡游客赏冰玩雪的脚步。在感受北国风光的同时，做好保暖同样重要。 前不久，河南游客曹依佳和朋友到黑龙江亚布力滑雪时，被冻伤了。 当时正是"三九"天，俗话说"三九四九冰上走"。出发前，她作足了准备，多加了衣裳。滑雪头盔自带耳 包，她以为足够保暖，就没额外再戴护耳。 滑雪大约半小时后，教练帮她拍照，她才发现耳朵有点不对劲儿。 拍了不一会儿，他右手小拇指和无名指的指甲开始变白，手指活动困难。意识到可能被冻伤了，他马上 去了附近的卫生所。医生初步判断是冻伤，给他开了冻伤膏。 当晚，他发现，冻伤的位置有些红肿，触碰时比较疼。又过了几天，两根手指开始脱皮，比较痒，大约 两周才恢复。 黑龙江中医药大学附属第二医院皮肤科主任刘拥军介绍，很多患者被冻伤后，往往忽略病情，认为没什 么大事。她曾接诊过一位外地游客，其左侧耳尖有点凉、有点硬，以为问题不大，结果回到宾馆不久便 出现水疱、痛痒症状。来就诊时，这位游客耳朵上的水疱已有蚕豆大小。 "风裹着雪往脸上刮，一开始还没感觉，后来突然耳朵就没知觉了。"曹依佳当时心里咯噔一下，"真的 ...

Core Viewpoint - The research on the Huayuan Biota reveals significant insights into the aftermath of the Cambrian mass extinction, highlighting the deep-sea environment as a refuge and a source of evolutionary innovation for various species [12][14]. Group 1: Discovery and Research Process - A gray stone slab, approximately palm-sized, contains a fossil of a planktonic organism from 500 million years ago, closely related to early vertebrates [3][5]. - The fossil was discovered in 2021 in Huayuan County, China, and underwent a meticulous five-year research process involving traditional geological tools and advanced digital technology [4][6]. - Over 50,000 fossil specimens were collected, with each being considered a "lucky" find due to their preservation over millions of years [8][10]. Group 2: Scientific Findings - The research identified 153 species within the Huayuan Biota, with 59% being new species, comparable in richness and diversity to other renowned fossil sites like the Cambrian Burgess Shale [12][13]. - The study provided evidence of long-distance dispersal mechanisms for Cambrian animals, suggesting that global ocean currents played a crucial role in species distribution [11][14]. - The deep-sea environment acted as a refuge during the mass extinction, allowing many species to survive and evolve, thus serving as a "hatching ground" for new life forms [11][14]. Group 3: Methodological Innovations - The research combined traditional paleontology with cutting-edge digital techniques, including advanced imaging and a global database of 3,149 species, which is unprecedented at the species level [9][10]. - The methodology emphasizes the importance of integrating fieldwork with data science to drive significant scientific discoveries [14]. Group 4: Implications for Local Community and Future Research - The findings are expected to provide new opportunities for the local community in areas such as rural revitalization and geological cultural tourism [14]. - Ongoing research will continue to explore the remaining new species and further decode the responses of ancient life to major crises [15].
