Omicron’s main subvariant mutating further, INSACOG rings alarm bells

Even as Covid-19 cases have seen a consistent fall in the number of daily cases reported in India, the Omicron variant may play spoilsport. According to Insacog scientists, Omicron’s BA.2.75 variant that has been the most dominant one may...

2 antibodies identified in Israel may fight all known Covid strains: Study

Scientists in Israel have isolated two antibodies from the immune system of recovered COVID-19 patients that may neutralise all known strains of SARS-CoV-2, including Omicron, with up to 95 per cent efficiency.The team at Tel Aviv University noted that...

Scientists discover ‘weak spot’ across all major Covid variants: Study

A team led by an Indian-origin researcher has discovered a key vulnerability across all major variants of SARS-CoV-2, the virus that causes COVID-19, including the recently emerged BA.1 and BA.2 Omicron subvariants.The weakness can be targeted by neutralising antibodies,...

Omicron, sub-lineages circulating predominantly in India: Report

The Indian SARS-CoV-2 Genomics Consortium (INSACOG), in a weekly meeting, reviewed the data of genomic surveillance of variants and found that at present, Omicron and its sub-lineages are the predominant mutations that are circulating in India.“Presently, only Omicron and...

New N95-like face mask can capture, deactivate Covid spike protein

A team of researchers, including one of Indian origin, has developed a medical face mask membrane similar to N95, which can capture and deactivate the SARS-CoV-2 spike protein on contact.SARS-CoV-2 is covered in spike proteins, which allow the virus...

Coronaviruses can survive on frozen meat for a month

A new study suggests that cousins of the SARS-CoV-2 virus can survive on frozen meat and fish for up to 30 days.The research -- prompted by COVID outbreaks in Asia in which packaged meat was suspected as the virus’...

How long-Covid risk varies by variant

The Omicron variant is less likely to give you long COVID than a previous strain of the virus, British researchers say.What was described as the first peer-reviewed report to investigate Omicron and patients’ risk of persistent symptoms found 4.4%...

Face mask that can kill Covid virus developed

Researchers have developed a new N95 face mask that can not only reduce COVID-19 spread but also kill the SARS-CoV-2 virus upon contact with it.The mask can potentially be worn longer, causing less plastic waste as it does not...
