New evidence shows SARS-CoV-2 mutations are not more transmissible
In direct contrast to previous research, researchers found that SARS-CoV-2 mutations are not tied to increased transmissibility in humans. The findings, published in Nature Communications on November 25 suggest that mutations such as D614G, while common, are neutral to viral evolution.  Discuss
Superspreader events drive global SARS-CoV-2 transmission
So-called "superspreader events" have been a major contributor to widespread transmission of the SARS-CoV-2 virus, according to a new analysis of outbreaks in Austria. Researchers used deep viral genome sequencing to trace the evolution of the pandemic in the country and how the virus spread beyond its borders, according to a study published in Science Translational Medicine on November 23.  Discuss
Families weigh risks of coronavirus exposure over Thanksgiving
Parents are weighing the risks and benefits of gathering with extended family this year, amidst the global COVID-19 pandemic. Most parents are planning to prioritize continuing Thanksgiving traditions while reducing transmission risks, according to a new national Mott Poll.  Discuss
CRISPR phage offers precision medicine tool to fight bacterial infections
In an attempt to combat bacterial infections, Locus Biosciences is developing bacteriophage therapies that deliver CRISPR-Cas3 machinery directly to specific, targeted pathogens to obliterate them. Locus CEO Paul Garofolo discusses the company's technology and recent updates with The ScienceBoard.net.  Discuss
What are the unresolved questions about SARS-CoV-2 T-cell responses?
Researchers have shed light on the "known unknowns" of preexisting and acquired T-cell responses in relation to SARS-CoV-2 infection. In a perspective piece, published in Science Immunology on November 18, scientists from Karolinska Institutet in Sweden discuss the role and durability of T-cell responses in COVID-19.  Discuss
Metabolic control of Tregs is critical for immune tolerance
A new study identifies how metabolism exerts control over regulatory T (Treg) cells, which play a key role in the recognition of foreign and self-produced molecules. The findings, published in Cell Metabolism on November 17, may help scientists identify new drug targets for autoimmune diseases and cancers.  Discuss
Why are children more resistant to SARS-CoV-2 infection?
Why do children seem to be more resistant to SARS-CoV-2 infection than adults? The answer may lie in the age-dependent presence of a key viral enzyme, transmembrane protease serine 2, according to a new study published in the Journal of Clinical Investigation on November 12.  Discuss
Interactive virtual reality system helps drug designers fight COVID-19
A new virtual reality tool offers scientists a chance to "step inside" the SARS-CoV-2 virus's main enzyme responsible for replication and manipulate it in atomic detail to find ways to shut it down. The technology could enable researchers in different locations to collaborate on drug development within a virtual environment.  Discuss
Why the most common SARS-CoV-2 strain spreads so easily
A new study confirms that the D614G mutant SARS-CoV-2 virus, which is now the most common form of the virus, is more easily transmitted among hosts but does not cause more severe disease than the original virus. The findings were published in Science on November 12.  Discuss
Improving the safety of gene therapies 2 different ways
Two groups of researchers have developed unique approaches to overcome the limitations of delivery of gene editing therapeutics. In a pair of new papers, researchers describe methods for more efficient and safe delivery of CRISPR components to targeted cells and tissues.  Discuss
