发帖数: 40861 | 1 Indiana turkeys to be euthanized in new avian influenza outbreak
The U.S. Dept. of Agriculture’s (USDA) Animal and Plant Health Inspection
Service (APHIS) confirmed the presence of highly pathogenic H7N8 avian
influenza (HPAI) in a commercial turkey flock in Dubois County, Indiana, on
January 15. This is a different strain of HPAI than the strains that caused
the 2015 outbreak.

发帖数: 5443 | 3 中国汉族血统还是很纯的，基因学证明中国历史上北方的民族融合几乎不存在
我们先做一个假设，如果中国北方真的发生了大规模的民族融合，那么突厥语民族
（匈奴、突厥）、蒙古语民族（鲜卑、契丹、蒙古）、满语民族（女真、满州），应该
和汉族有相同的共有Y染色体类型分布。
但我们研究R1a1、C3c、O2b三个染色体类型，却发现，汉族人中找不到这三种类型
的Y染色体。
首先说C3c，复旦大学生命科学院数据库里有560多个北方汉族样本、1200多个南方
汉族样本（2004年时），里面居然没有一个C3c，而在外蒙地区的蒙古人中，这个比例
为17%，在哈萨克族人中为12%，在图瓦人中24%，也就是在突厥语和蒙古语民族人口中
出现频率都特别高！而560多个汉族和1200多个南方汉族人群样本中，竟然没有一个是
C3c，基本排除了历史上突厥语、蒙古语民族和汉语人群的大规模融合，至少在父系上
的Y染色体中找不到证据。
其次再说R1a1，这个是中亚突厥语民族特有基因，在乌兹别克人中为20.1%，在
Hkoton人中为80%以上，而在汉族人中，没有发现R1a1，汉族人中有将近1%的R1和P，但
不是R1a1，而是他们... 阅读全帖 |

Over the past 100 years, there have been four flu pandemics: 1918 H1N1
Spanish flu [6], which has been described as "the greatest medical holocaust
in history" [7], 1957 H2N2 Asian flu, 1968 H3N2 Hong Kong flu, and 2009
H1N1 swine flu. The most serious pandemic occurred in 1918, killing more
than 50 million people worldwide [8]. Since 1996, the highly pathogenic
avian influenza (HPAI) virus (H5N1) has caused more than 1000 deaths,
