Can cooling ingredients in e-cigarettes cause irregular heartbeat or cardiac arrest?

Research Highlights: Adding cooling ingredients to e-cigarettes resulted in mis-timed heartbeats that could increase the risk for sudden cardiac arrest, according to a study conducted in mice and in l...

Cooling additives in e-cigs aren’t harmless. New work from the Carll Lab shows synthetic coolants (WS‑3, WS‑23) ↑ autonomic imbalance and trigger ventricular arrhythmias—independent of nicotine. Implication: “ice” flavors may elevate cardiac risk beyond nicotine alone. #Vaping #Cardiosky

Scientists are raising the alarm about a White House proposal that could fundamentally recast federally funded science. The proposed rules would put political appointees in control of all federal grants and de-emphasize peer review, among other measures. go.nature.com/4ucZgsk

70% of ppl believe at least one false or unproven health claim — such as ‘risk of childhood vax outweighs benefits’ or ‘paracetamol use during pregnancy causes autism’, suggests a new survey. My story for @nature.com examines the questioning of scientific evidence www.nature.com/articles/d41...

Congratulations to Dr. Brittany Reynolds, a former Trainee in the Laboratory of Dr. Alex Carll, who received the Paper of the Year Award from the Cardiovascular Toxicology Specialty Section of the Society of Toxicology at their recent annual meeting.

Really proud of Dr. Ramalingam for not only generating but also demystifying this very complicated dataset. Wishing he had been able to visit from Hungary to receive this honor at SOT in person himself.

Congratulations to Drs. Anand Ramalingam and Alex Carll, for receiving the Paper of the Year Award from the Inhalation and Respiratory Specialty Section of the Society of Toxicology (SOT) at their recent annual meeting.

Next, at the Society of Toxicology conference, on Tuesday afternoon, Dr. Brittany Reynolds, a former PhD student in the Laboratory of Dr. Alex Carll, will present her thesis research showing that beta-blockade prevents e-cigarette-induced arrhythmias during and after pregnancy.#Toxicology#SOT2026
