Digital contact tracing could help suppress COVID-19 outbreaks
A model of COVID-19 spread has shown the utility of digital contact tracing in reducing outbreaks to manageable levels. …
Read Full ArticleModeling study examines impacts of one versus two doses of a COVID-19 vaccine
Receiving just one dose of a two-dose COVID-19 vaccine tends to decrease infections in the short-term but may increase the potential for immune escape mutations in the longer-term. …
Read Full ArticleMutant proteins from SARS-CoV-2 block T cells’ ability to recognize and kill infected cells
Study highlights the capacity of SARS-CoV-2 to subvert immune surveillance through mutations that hamper T cell responses. …
Read Full ArticleSARS-CoV-2 UK variant is more transmissible and could spark resurgences
A new modeling study shows a SARS-CoV-2 UK variant is more transmissible than pre-existing variants and without stringent control measures could lead to large resurgences of COVID-19 cases. …
Read Full ArticleBioNTech-Pfizer mRNA vaccine largely effective against SARS-CoV-2 UK variant
In a study evaluating the BioNTech-Pfizer COVID-19 vaccine’s ability to neutralize the SARS-CoV-2 UK variant, researchers found no loss of immune protection compared to the original Wuhan strain. …
Read Full ArticleAnalysis of SARS-CoV-2 immune response several months post-infection hints at protective immunity
A new study reports that immune memory to the SARS-CoV-2 virus was measurable for up to 8 months after infection. …
Read Full ArticleStress hormones can reawaken sleeping tumor cells, raising risk of cancer recurrence
Stress hormones and immune cells called neutrophils may contribute to the recurrence of tumors years after treatment by awakening dormant cancer cells …
Read Full ArticleTwo-way transmission of SARS-CoV-2 on mink farms
Whole-genome sequencing of SARS-CoV-2 in outbreaks on 16 mink farms has revealed virus transmission between humans to mink, as well as from mink to humans. …
Read Full ArticleA ‘cell-less’ therapy may regenerate heart tissue without cell transplant risks
Researchers have developed a strategy that uses exosomes – tiny membrane-bound sacs secreted by cells – to mimic the heart-regenerating effects of cardiac cell transplants …
Read Full ArticleDNA nanoswitches rapidly detect SARS-CoV-2 and other emerging viruses
Programmable DNA nanoswitches that bind to viral RNA in human body fluids may provide an inexpensive platform to rapidly detect a wide variety of emerging viruses, including SARS-CoV-2 …
