Researchers at Lehigh University have identified differences in the protein composition of bone marrow extracted from the hip versus the shoulder—an insight that could help refine regenerative treatments for joint injuries. The study, published in ACS Omega, used machine learning models to analyze 109 proteins and found six that may distinguish between the two extraction sites. The findings highlight how the source of bone marrow aspirate can influence its biological makeup, offering a framework for more standardized analysis of bone marrow-based therapies and other biological tissues.

Depending on where you live in the United States, the meat you eat each year could be responsible for a level of greenhouse gas emissions that's similar to what's emitted to power your house. That's according to new research from the University of Michigan and the University of Minnesota published in the journal Nature Climate Change.
