Electric shock revealed that worms may have "emotions"

Researchers discovered that Caenorhabditis elegans worms exhibit persistent brain activity and ignore food when subjected to electrical stimulation, suggesting a basic emotional response. The study suggests that genes controlling emotions in worms may have counterparts in humans, potentially leading to new treatments for mood disorders.

E-cigarettes are not a gateway into smoking

A comprehensive study found no evidence that e-cigarettes promote smoking and may even compete against cigarettes, potentially speeding up the decline in smoking rates. The study compared countries with different e-cigarette regulations and found a slower decline in smokers among those with stricter controls.

Study shows B-type natriuretic peptides lose prognostic value for clinical outcomes in LVAD recipients with cardiogenic shock

Researchers at the University of Alabama at Birmingham found that BNP levels are high in end-stage heart failure patients with cardiogenic shock, but no longer a reliable predictor of clinical outcomes after ventricular assist device (VAD) implantation. This study suggests reevaluating routine use of BNP testing for these patients.
