Researchers found three viruses that share a key feature with SARS-CoV-2, the coronavirus that caused COVID-19, in greater horseshoe bats living in limestone caves in Laos. Scientists are hopeful that they are now closer to finding the cause of the current pandemic.
Researchers from the University of Minnesota developed a novel virus-like nanoparticle vaccine that has been tested on animals, offering a new approach in a human vaccine against COVID-19 and its variants.
Even though the delta variant was around the corner, New Zealand is equipped with a whole new level of coronavirus testing. New Zealand prevented the transmission of the COVID-19 delta variant through the help of real-time genome sequencing.
In Indonesia, two rare Sumatran tigers tested positive for COVID-19 last month and are being treated by zookeepers. Jakarta officials are now investigating the cause of the infection as none of their caretakers and zoo staff have the infection.
An American scientist recovered deleted virus sequence a year after it was removed from the public database Sequence Read Archive. Finding the missing genetic sequence data is valuable in determining the origin of SARS-CoV-2.
