Wearable sweat sensor tracks vitamin levels in real time

Researchers developed a wearable electrochemical patch that detects six vitamins in sweat at nanomolar levels, combining sweat induction, microfluidic sampling, wireless readout, and pH/ionic-strength calibration. Human testing focused mainly on vitamin B9, showing sweat levels rose after supplementation or a vitamin B9-rich diet and correlated with serum levels, supporting future use for non-invasive nutrition trend monitoring.

TikTok chatter could help predict where the opioid crisis is heading next

A large-scale analysis of 569,581 TikTok comments found that opioid-related discussions may help track and forecast synthetic opioid overdose mortality in the US. Recovery, harm reduction, drug use, drug sourcing, and loss-related conversations provided near-real-time signals that improved 6-month forecasting accuracy.

Why H2N2 flu is back on the pandemic preparedness radar

A historical review in Vaccine warns that global H2N2 immunity has sharply declined since the 1957 Asian influenza pandemic, leaving most people without H2-specific protection if the virus re-emerges. The authors highlight animal reservoirs, waning birth-cohort immunity, and modern H2 vaccine platforms as key priorities for pandemic preparedness.

Modeling the synergy of maternal screening and newborn HBV vaccination

Hepatitis B virus (HBV) infection acquired at birth or during early infancy can lead to lifelong health complications, including chronic liver disease. Despite longstanding recommendations for prenatal screening, an estimated 12% to 16% of pregnant individuals in the US are not screened for hepatitis B. This gap leaves a portion of newborns at risk for undetected exposure.
