COVID-19 Vaccines May Trigger Superimmunity In People Who Had SARS Long Ago
sciencehabit shares a report from Science Magazine: Almost 20 years before SARS-CoV-2, a related and even more lethal coronavirus sowed panic, killing nearly 10% of the 8000 people who became infected. But the 2003 outbreak of severe acute respirator.....»»
New CRISPR-based technology could revolutionize antibody-based medical diagnostics
Scientists have repurposed the genetic modification technology CRISPR to identify antibodies in patient blood samples in a move that could inspire a new class of medical diagnostics in addition to a host of other applications......»»
Microbial study reveals extended lifespan of starved bacteria
A study of microbial populations under a prolonged period of starvation by Indiana University professor Jay T. Lennon and his laboratory could help researchers answer questions pertaining to chronic infections, the functioning of bacteria in the envi.....»»
A fast, accurate system for quickly solving stubborn RNA structures
The single-stranded genetic material RNA is best known for guiding the assembly of proteins in our cells and carrying the genetic code for viruses like SARS-CoV-2 and HIV. But 40 years ago, scientists discovered another hidden talent: It can catalyze.....»»
Tripod expects new PCB plant in China to drive growth in 2H21
