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

A |     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。    虽然这段视频有些年头了，但能够让你很好地了解地球上的冰全部融化之后的场景，以及海平面上升对许多国家的影响。结果与您预期的一样令人震惊，美国的整个地区都沉入了海底。佛罗里达州和乔治亚州等州完全消失在上升的水位之下。目前科学家不断提出解决方案来阻止冰架融化。

B | 有些计划比其他计划更加激烈和绝望，科学家甚至建议将二氧化硫释放到南极洲上空的大气中，以减缓气候变化和地球无冰的可能性。它可能有助于遏制气温上升，但也会导致酸雨落在土地上。尽管如此，找到抑制影响的长期解决方案仍然至关重要，尤其是在全球气温持续上升的情况下。虽然 NASA 正在让我们更容易看到气候变化的影响，但目前还没有采取任何重大措施来阻止它。
