A new study published in the Journal of Addiction Medicine found that CUD diagnoses rose substantially across all age, race/ethnicity, and comorbidity subgroups nationwide from 2000 to 2022. These diagnoses were consistently higher among people living with HIV, compared to people living without HIV, and people over 65 experienced the greatest relative increase. 

Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The discovery will allow researchers to engineer technologies that make use of the technique to develop applications in fields such as biomedical testing and drug development.
