Advances in nanotechnology have made it possible to fabricate structures out of DNA for use in biomedical applications like delivering drugs or creating vaccines. Still, new research in mice investigates the safety of the technology. Using a technique called DNA Origami (DO) – a process that involves folding complementary strands of DNA into double helixes over and over again...

New lung-cancer screening guidelines reduce disparity
THOMAS JEFFERSON UNIVERSITY (PHILADELPHIA) – In 2013, the US Preventive Task Force (USPSTF) published guidelines that recommended individuals at high risk for developing lung cancer who met the eligibility criteria, undergo annual lung screening by low-dose CT scan. However, these guidelines, in effect, excluded many African Americans who are often diagnosed with late-stage lung cancer...

Scientists create nanoparticle that helps fight solid tumors
by Wake Forest University Baptist Medical Center Design and characterization of NP700-ARL. (A) Scheme illustration of the self-assembly of NP700-ARL. In this delivery system, (1) the photosensitizer-containing lipid polymer DSPE-PEG-IR700 is a “ROS-producing” component, which damages tumor cells and induces ATP release under light irradiation; at the same time, it produces ROS as stimuli to...
