A novel screening method for Parkinson’s disease (PD) analyzes the volatile compounds in ear wax to detect early signs of the condition. Researchers found that four specific volatile organic compounds (VOCs) are significantly different in people with PD.
Alzheimer’s Risk Linked to Increased Social Activity, Not Isolation
Contrary to popular belief, a new study suggests that people with a higher genetic risk for Alzheimer’s may become more socially engaged—not less. Researchers analyzed data from over 500,000 individuals and found that higher-risk participants reported lower social isolation and more positive family interactions.
RyR1 Channel Triggers Sedation from Anesthetics
A new study uncovers the long-elusive mechanism of inhalational anesthetics by identifying the RyR1 calcium channel as a key molecular target. Researchers demonstrated that anesthetics like isoflurane activate RyR1 to trigger calcium release from the endoplasmic reticulum, a crucial step in inducing general anesthesia.
