Real-time imaging reveals 'RNA hub' driving adaptive immune response
A lot of things need to go right on a molecular level for immune cells to launch an adaptive response to an infection. B cells can produce different classes of antibodies tailored for specific infections through controlled DNA damage and repair that alter the genetic information

One tiny mutation may explain how bat viruses become human threats
One tiny mutation may explain how bat viruses become human threats
Scientists found that one tiny genetic change can completely alter how a coronavirus behaves in different species. Comparing SARS-CoV-2 with a closely related bat-only virus, they showed that a single amino-acid difference affects whether the immune system fights back or gets sup

How atomic defects can program carbon quantum dots for future light-based technologies
How atomic defects can program carbon quantum dots for future light-based technologies
Carbon quantum dots (CQDs) are tiny carbon-based nanomaterials that have attracted increasing attention as environmentally friendly alternatives to conventional heavy-metal quantum dots. They are lightweight, photostable and potentially biocompatible, and their light absorption a
