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

一 |     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。    距离8月19日七夕节还有不到两周时间，全国多地婚姻登记处已迎来预约高峰。在杭州，上城区、西湖区、滨江区、萧山区、钱塘区等多个婚姻登记处8月19日的线上预约名额已被“秒空”，拱墅区也仅剩个别时段尚有余额。目前，只有余杭区等少数登记处还有少量名额可预约。“七夕是传统节日，很多情侣都觉得这一天领证特别有仪式感。”杭州市民政局工作人员介绍，为应对即将到来的结婚登记小高峰，七夕当天全市各婚姻登记处将全面开放所有登记窗口，并通过增派工作人员、提前到岗、午间轮休、延迟下班等方式，最大限度满足新人们的登记需求。自2025年5月10日起，新修订的《婚姻登记条例》正式施行，婚姻登记不仅取消了地域限制，更不再需要户口本，真正实现了全国通办。这意味着，无论新人在哪里，都可以就近选择婚姻登记机关办理登记。
