Exposure to the rhinovirus, the most frequent cause of the common cold, can protect against infection by the virus which causes Covid-19, researchers have found. The study by Yale researchers found that the common respiratory virus jump-starts the activity of interferon-stimulated genes, early-response molecules in the immune system which can halt replication of the SARS-CoV-2 virus within airway tissues infected with the cold.
Covid-19 Delta variant, first identified in India, doubles the risk of hospitalisation compared with the Alpha variant first found in the UK, but Pfizer and AstraZeneca vaccines provide good protection against the strain, says a study in The Lancet. Researchers found that the Pfizer-BioNTech vaccine offered better protection against the Delta variant compared to Covishield.
A large segment of a Chinese rocket re-entered the Earth's atmosphere and disintegrated over the Indian Ocean, state television reported Sunday citing the China Manned Space Engineering Office, following fevered speculation over where the 18-tonne object would come down. Most of the segment disintegrated and was destroyed during re-entry, the Chinese agency confirmed.
If you are planning to avoid vaccination just because you are a Covid survivor, think twice. According to a new study, despite a prior Covid-19 infection young people can likely catch the virus again and may still transmit it to others.
Patients are at an estimated 44 per cent greater risk of neurological and mental health diagnoses after Covid-19 than after flu, and a 16 per cent greater risk than with other respiratory tract infections, the largest study of its kind by the University of Oxford revealed on Wednesday.
Scientists have been scrutinising a Noah's Ark of animals to find out whether -- and how -- the coronavirus was transmitted from bats to humans, with the prime suspect changing from one study to another. Cats, dogs, badgers, lions and tigers have also been in the spotlight -- not to mention minks, which have been culled in the millions.
