Researchers at Kanazawa University and the University of Tokyo report in Nature Communications the visualization of the dynamics of 'molecular scissors' — the main mechanism of the CRISPR-Cas9 genetic-engineering technique.
An antiviral drug that inhibits a virus' replication machinery selectively targets the most-aggressive viruses, according to new research that looked at the infection of individual cells by a virus and the consequence of antiviral intervention. This new insight into the dynamics of an infection and the mechanism of an antiviral drug could not be seen by the typical approach of studying populations of cells. Researchers at Penn State, Duke University, and the University of Texas at Austin have developed a high-throughput system to study large numbers of single, infected cells that facilitated the new insight.
Use of the blood thinner warfarin was associated with a lower risk of new cancers in people over 50.
Dr. Jason Butler and his team discovered that aged blood vessels strongly influence the functional characteristics of blood stem cells. Transplantation of young blood vessel cells into older mice makes their aged stem cells take on the characteristics of young stem cells.
