New system facilitates real-time imaging of biological, pathological processes

Researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, have developed a novel far-red light-emitting luciferin-luciferase system that is more efficient than those available commercially. An article on the subject is published in the International Journal of Molecular Sciences.

FDA-approved cancer drug blunts SARS-CoV-2 protein's detrimental effects

University of Maryland School of Medicine (UMSOM) researchers have identified the most toxic proteins made by SARS-COV-2 - the virus that causes COVID-19 – and then used an FDA-approved cancer drug to blunt the viral protein's detrimental effects. In their experiments in fruit flies and human cell lines, the team discovered the cell process that the virus hijacks, illuminating new potential candidate drugs that could be tested for treating severe COVID-19 disease patients.

Intelligent near-infrared vein scanner may make blood draws much easier

Researchers from Skoltech have developed an early prototype of a medical imaging system that uses neural networks to analyze near-infrared images of veins and project a venous pattern onto a patient's body - this may make blood draws much easier and less of a nuisance for patients with difficult access to veins.
