Twisted Edison: Bright, elliptically polarized incandescent light

University of Michigan
Peer-Reviewed Publication

Bright, twisted light can be produced with technology similar to an Edison light bulb, researchers at the University of Michigan have shown. The finding adds nuance to fundamental physics while offering a new avenue for robotic vision systems and other applications for light that traces out a helix in space.

Firearm and motor vehicle pediatric deaths— intersections of age, sex, race, and ethnicity

JAMA Network
Peer-Reviewed Publication

About The Study: In this cross-sectional study, U.S. youths ages 0 to 19 years experienced important disparities in firearm and motor vehicle crash fatality rates and increases over time when considering the intersectionality by age group, sex, race, and ethnicity. These findings suggest that a multipronged strategy focused on individual, community, and policy level approaches for specific high-risk groups for each injury mechanism is necessary to address these leading causes of death in U.S. youths.

Identification of chemical constituents and blood-absorbed components of Shenqi Fuzheng extract based on UPLC-triple-TOF/MS technology

Xia & He Publishing Inc.
Peer-Reviewed Publication

Shenqi Fuzheng (SQ) is a widely used Chinese medicine formula known for its immune-enhancing and Qi-supplementing properties. However, the blood-absorbed components of SQ and their pharmacokinetics remain underexplored. This study aimed to comprehensively analyze the chemical constituents of SQ and investigate their absorption and pharmacokinetic behavior in rat plasma.

High-quality nanodiamonds for bioimaging and quantum sensing applications

Okayama University
Peer-Reviewed Publication

Researchers have developed nanodiamond sensors with nitrogen-vacancy (NV) centers, offering exceptional brightness and spin properties for quantum sensing and bioimaging. These nanodiamonds outperform commercial options, requiring 20 times less energy and maintaining quantum states 11 times longer. Enhanced sensitivity to magnetic fields and temperature enables precise applications, including disease detection, battery analysis, and thermal management of electronics, marking a significant advancement in nanotechnology-driven quantum sensing for biological and industrial innovations.
