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.
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
Thirteen of the US NIH’s advisory councils, which must review grant applications before funding is awarded, are on track to have no voting members

US federal agencies were gutted in 2025, losing ~20% of their staff relative to 2024.
Global warming surpassed 1.5 degrees Celsius for the past three years, meaning Earth is currently on track to breach the Paris climate agreement by the end of the decade
While Louisville has plenty of room for improvement, its cycling infrastructure is one of the features I truly appreciate here. I eagerly await my daily bike commutes once I graduate from elementary school taxi driver.

Congrats to Brittany Reynolds of @cardiometabosci.bsky.social for successfully defending her dissertation today! Way to represent the team with a straightforward talk and meaningful insights how e-cig exposures evoke arrhythmias! Now to get this last cherry on the top submitted and published!
Today’s nanosecond pause in the news cycle 🥱 is a great excuse to hop on over to the AJP-Heart podcast about Brittany Reynolds’ concerning findings that vaping may increase postpartum arrhythmias 😱

A single dose of psilocybin reduced pain, pain-induced anxiety and depression-like behaviors in mice, according to a study published in Nature Neuroscience. 🧪
Disagreement, sure. 2 schools of thought, no. Most of us realize and routinely acknowledge the uncertainty re: health effects. Advocating for vaping altogether without acknowledging need for regulation to reduce youth appeal and prevent youth uptake seems naive and irresponsible.
This is a false dichotomy. There’s more nuance in the scientific discussion about the merits and/or harms of e-cigs. You somehow missed I am “they” and my “claims” regard my scientific results and their implications, which I believe. The suggestion there are “2 schools of thought” is false.
Thank you for the clearly baited lead into this with an ambiguous loaded question 🤣. I will read these with an open mind as soon as I am able.
What claims, and who are they?

Don’t go vaping my heart, especially when pregnant💨 🫀🤰 Want to know why? Find out more in the latest publication by the Alex Carll, PhD, lab in AJP-Heart, led by PhD student, Brittany Reynolds. journals.physiology.org/doi/abs/10.1...
Proud of Anand Ramalingam for coalescing this data to show repeat e-cigarette exposure transiently evokes arrhythmias via the beta1 adrenoceptor, consistently increases BP, changes the cardiac proteome, and persistently depresses HR and ventricular repolarization. www.ahajournals.org/doi/full/10....

We need to make pregnancy and the postpartum period safe for all women. Currently, maternal mortality rates are at an all time high in the US. In order to make things safer, we need more funding, research, and representation. pubmed.ncbi.nlm.nih.gov/39832282/

This is figure 3, which shows city-level net changes in temperature-related excess death rates for each warming level under scenario SSP3-7.0 and no adaption to heat.
Temperature-related deaths in European cities could increase by up to 50% by the end of the century in the absence of climate change-mitigation policies, totalling up to 2.3 million additional deaths, suggests a paper published in Nature Medicine. https://go.nature.com/4glnYzU 🧪
