Scientists develop new Covid strain with 80 pc kill rate in mice_我的网站

A |     SpaceX当地时间8月25日宣布，计划斥资1000亿美元在美国路易斯安那州南部沿海湿地新建发射场，用于支持每年数千次星舰飞行。该发射场预计将于明年开建，将创造超3000个新就业岗位。    Washington, Oct 18 (UNI) Scientists at Boston University has developed a new Covid-19 strain which resulted in an 80 per cent kill rate in mice.

The variant, a combination of Omicron and the original virus in Wuhan, killed 80 per cent of the mice infected with it, the university said. When mice were only exposed to Omicron, they experienced mild symptoms, the New York Post said.

A team of scientists from Florida and Boston at the school’s National Emerging Infectious Diseases Laboratories conducted the research.

They extracted the spike protein from Omicron and attached it with the strain first detected at the onset of the pandemic that began in Wuhan, China. They then documented how the mice reacted to the hybrid strain, according to the New York Post report.

“In…mice, while Omicron causes mild, non-fatal infection, the Omicron S-carrying virus inflicts severe disease with a mortality rate of 80 percent,” they wrote in a research paper.

The new strain has five times more infectious virus particles than the Omicron variant, researchers said.

UNI PRT。美国路易斯安那州经济开发局声明称，该项目全面建成后，预计将包括五个发射综合体，每个综合体配备两个发射台和一个推进剂储存设施。此外，该项目还将包括推进剂生产设施、发电厂、航天器处理设施以及员工与家属住宅。
