11 papers retracted from a PhD student. Surprising? Not really. Just check the recent news: 1. The rector of a Spanish university ran a citation-inflation scheme. He was one of Spain’s most-cited academics. Springer Nature retracted 75 papers linked to him in 2024. 2.

See our recent work in @AmJSurgery, which presents one of the largest single-center analyses of blunt cerebrovascular injuries ever performed, highlighting key stroke risk factors. @EmorySurgery @EmoryatGrady

Minimal literature correlates stroke rates in blunt cerebrovascular injury (BCVI) to bilaterality, multi-vessel injury, or multifocal injury. We hypothesized that a synchronous cerebrovascular injury...

I’m heartbroken to share the shooting in Lexington at Richmond Road Baptist Church has taken the lives of two people. Other injuries — including a Kentucky State Police trooper from the initial stop — are being treated at a nearby hospital. The shooter has also been killed. 1/3

p-values supposedly measure the correlation between interventions and outcomes. But what happens when a measure becomes a target?

Remind me what happens when a measure becomes a target.

Some studies (including work published in Science in 2023) have indicated that taurine concentrations decline with age, and supplementation has been suggested to improve both healthspan and lifespan. A new Science study now reports results that show taurine is not a reliable

Anti-aging effects of popular supplement taurine challenged. This new study is “more convincing” than the previous one, says David Sinclair @Nature

Very humbled to have contributed to this work. See our recent paper in Science, where we challenge the idea that circulating taurine is a biomarker of aging:
science.org
Low circulating taurine concentrations have been proposed as a driver of the aging process. We found that circulating taurine concentrations increased or remained unchanged with age in three geogra...

NotebookLM generates AI podcasts but you can't use it on the phone. Paper2Pod is a free iPhone app that turns research papers into audio podcasts, so you can listen to them on the go. Here's how to use it:

Triple duty from @ChrisL_He repping the lab at #ISHLT2025 1️⃣ Uncomplicated HM3 long-term outcomes as good as OHT 2️⃣ EVLP enables use of higher-risk lungs with comparable survival 3️⃣ Impella support up to 93 days shown to be safe @EmoryCTSurgery @EmoryLungtxp:

A flow chart for every single variable type you could think of in data science (I think). I made this because I had such a hard time remembering all the terminology and categories. Hope this helps if you also struggle with remembering all this!!!
