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。 (ECNS) -- Chinese customs anti-smuggling authorities and the Australian Border Force have seized more than 90 million smuggled cigarettes in a joint operation against a transnational network that moved counterfeit tobacco products through China to Australia, China’s Ministry of Public Security said Thursday. Investigators found counterfeit tobacco concealed among legitimate goods and shipped through China to Australia. Earlier, Chinese authorities dismantled nine smuggling groups and storage sites, seizing 32 million cigarettes. Intelligence shared with Australia led to coordinated action, with Australian officials seizing 60 million cigarettes and 60 kilograms of tobacco. 。
