A discovery about how severe COVID-19 damages lung cells suggests that an existing drug could treat lingering respiratory problems not just from COVID but influenza and other respiratory infections.

Researchers at Duke University and North Carolina State University have discovered a handful of new CRISPR-Cas systems that could add to the capabilities of the already transformational gene editing and DNA manipulation toolbox. Of the new recruits, one system from bacteria commonly found in dairy cows shows particular promise for human health.

Researchers at the RNA Institute at the University at Albany are pioneering new methods for designing and assembling DNA nanostructures, enhancing their potential for real-world applications in medicine, materials science and data storage. Their latest findings demonstrate a novel ability to assemble these structures without the need for extreme heat and controlled cooling. They also demonstrate successful assembly in unconventional “buffer” substances including nickel. These developments unlock new possibilities in DNA nanotechnology.
