Challenges and future directions for Mendelian randomization - Nature Genetics Mendelian randomization is widely used but relies on specific assumptions that are rarely systematically assessed. This Perspective argues that researchers should rigorously test these assumptions thr...

We have a new paper outlining the latest challenges and future directions for Mendelian randomization.

We used AI to review 10,126 abstracts from studies using Mendelian randomization.

Cover of JAMA Cardiology features Robert O. Bonow, MD, MS, along with the text 'The First Decade of JAMA Cardiology'. Published online January 30, 2026.

JAMA Cardiology marks its 10th anniversary with gratitude to founding Editor in Chief Robert O. Bonow, MD, MS.

In his farewell Editorial, Bonow reflects on building a top-cited cardiovascular journal: “It’s a very rare, once‑in‑a‑lifetime opportunity.”

Amid the hype of using polygenic scores for embryo selection, some thoughts on their implementation potential in real-world settings (and problems) 👇

Massive multi-ancestry GWAS resource for 1,167 clinical traits & diseases in 6 global biobanks (n=1,789,365)

👉29,139 locus-trait pairs
👉2,624 non-overlapping loci across the genome
👉associated with 6 traits each (median)
👉colocalization across traits for 72% of loci [1/3]

Very excited to share our preprint led by M. Levin @skoyama.bsky.social J. Woerner & with S. Damrauer assessing genome-wide pleiotropy of >1,000 clinical traits across ~1.7M individuals with nearly 30K locus-trait associations!

Figure 2. Concordance of Individual Scores in the Primary All of Us (AOU) Research Sample

Despite similar performance at the population level, different coronary heart disease polygenic risk scores produced highly variable individual-level risk estimates.
