SNMMI introduced a new slate of officers during its 2025 Annual Meeting, held June 21-24 in New Orleans.

In a step toward treating mitochondrial diseases, researchers in the Netherlands have successfully edited harmful mutations in mitochondrial DNA using a genetic tool known as a base editor. The results, published June 24^th in the open-access journal PLOS Biology, offer new hope for people with rare genetic conditions.

A groundbreaking study in PLOS Biology from researchers at Harvard University, offers a fresh and compelling answer to the fundamental evolution mystery of how mammals went from sprawling like lizards to upright; revealing the path to upright posture wasn’t linear, but full of unexpected detours, evolutionary experimentation, and dramatic anatomical upheaval.

The transition from sprawling (reptile-like) to more upright (parasagittal) posture and locomotion was a transformative event in mammalian evolution. A study published June 24^th in the open-access journal PLOS Biology by Dr. Robert Brocklehurst and Professor Stephanie Pierce at Harvard University, USA and colleagues suggests that parasagittal posture evolved via an indirect, dynamic, and radiating process.

A trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California Davis, US, and colleagues report June 24^th in the open-access journal PLOS Biology.

Has your skin ever felt tight and dry after coming out of the ocean? You’re not just imagining it. Scientists from Binghamton University, State University of New York have confirmed what beachgoers have felt for years – saltwater dries out your skin – and why it happens.
