Micelle Technology Detects Airborne SARS-CoV-2
At the Pacific Northwest National Laboratory, researchers have developed micelle technology that can detect minute amounts of SARS-CoV-2 in the air. This new capability could provide invaluable monitoring systems to detect viral contamination in healthcare facilities and beyond. Micelles are somewhat similar to liposomes in that they are both like tiny lipid bubbles. In this instance, the researchers incorporated molecularly imprinted polymer molecules into the wall of the micelles. These molecularly imprinted molecules can bind to the viral spike protein. On viral binding, the polymer molecules cause the micelle to burst,...

Antibodies Against SARS-CoV-2 Nucleocapsid Protein May Not Be Reliable Markers for Infection in Vaccinated People
by Gertrud U. Rey You are fully vaccinated against SARS-CoV-2 and have presumably never been infected with the virus. But how can you know for sure? One way to find out is by testing your blood for the presence of antibodies against the viral nucleocapsid protein, which can only be encountered during natural infection. This […] (Source: virology blog)

mRNA Therapy Prevents COVID Virus Entering Cells
Scientists at Oregon State University have developed a new treatment for COVID-19. The technology is based on mRNA, which has also been put to good use in COVID-19 vaccines. However, in this instance, the delivered mRNA encodes for human angiotensin-converting enzyme 2 (hACE2), which is the binding site for SARS-CoV-2 on airway cells.
The lipid nanoparticle-encapsulated mRNA therapeutic is delivered to cells in the body, and then the cells begin to produce and release a free-floating form of hACE2 that acts as a decoy to soak up viral particles. Once the viral particles are bound to the decoys, they are no longer avail...

The college football fans that beat COVID and the experts that couldn ’t
BY ANISH KOKA
The COVID pandemic was supposed to herald the end of the idea that a smaller government is a better government. The experts who desperately seek to be in charge of a sprawling bureaucratic state told us that it was only a powerful central authority that could do what was needed to safeguard individual liberties at a time when a highly contagious respiratory virus was spreading across the globe.
New Zealand may have imposed draconian policies that did not even allow its own citizens to return, but scenes of cheering unmasked New Zealanders stood in sharp contrast to empty seats in American stadiums when ...
