UrduNew research from UNC Charlotte’s Center for Computational Intelligence to Predict Health and Environmental Risks has found that the two most prevalent strains of the virus that cause COVID-19, SARS-CoV-2 variants BA.2.86 and JN.1, are not significantly better than their predecessor Omicron at evading immune responses and causing infections despite having a high number of mutations compared to previous variants.

Long-Term Data Reveals SARS-CoV-2 Infection and Vaccine-Induced Antibody Responses Are Long-Lasting
New study results challenge the idea that vaccine immunity fades quickly
Researchers Find COVID-19 Causes Mitochondrial Dysfunction in Heart and Other Organs
A multi-institutional consortium of researchers has found that the genes of the mitochondria, the energy producers of our cells, can be negatively impacted by the virus, leading to dysfunction in multiple organs beyond the lungs. These findings suggest new approaches for treating COVID-19.
Air monitor can detect COVID-19 virus variants in about 5 minutes
Now that the emergency phase of the COVID-19 pandemic has ended, scientists are looking at ways to surveil indoor environments in real time for viruses. By combining recent advances in aerosol sampling technology and an ultrasensitive biosensing technique, researchers at Washington University in St. Louis have created a real-time monitor that can detect any of the SARS-CoV-2 virus variants in a room in about 5 minutes.
Cholesterol lures in coronavirus
New study shows that cholesterol aggregates can promote SARS-CoV-2 infection to help the virus invade cells
SARS-CoV-2 seasonal behavior traced back to genetics and global change
As the northern hemisphere heads into summer, we may be in for a COVID-19 reprieve. Not because the pandemic is over; the Omicron subvariant ‘Arcturus’ is still creeping upward and causing new symptoms. But two new studies from the University of Illinois add evidence supporting a seasonal pattern in the behavior of the SARS-CoV-2 virus.
Key Change in Genetics of SARS-CoV-2 Evolved to Counter Weakness Caused by the Virus’ Initial Mutation that Enabled Its Spread
Researchers at Johns Hopkins Medicine say their new studies suggest that the first pandemic-accelerating mutation in the SARS-CoV-2 virus, which causes COVID-19, evolved as a way to correct vulnerabilities caused by the mutation that started the SARS-CoV-2 pandemic.
Study Explores Sex Differences in the Effects of SARS-CoV-2 in Young Adults
Suggests a more proactive, innate immune response among females
Rapid, at-home prototype saliva test that’s as good as RT-PCR
At-home COVID-19 tests have become an easy way to self-diagnose. But current tests have drawbacks. Now, researchers reporting in ACS Sensors have developed a SARS-CoV-2 saliva assay and prototype device that combine speed and ease with high sensitivity.
Scientists develop tools for early detection of SARS-CoV-2 variants in wastewater
New tools developed at Scripps Research and UC San Diego are helping public health officials around the world get vital information about pathogen variants from wastewater.
COVID-19 Rebound after Taking Paxlovid Likely Due to Insufficient Drug Exposure
COVID-19 rebound following Paxlovid treatment likely due to insufficient drug exposure, UC San Diego researchers find after showing rebound patient did not show drug resistance or impaired immunity.
