Scientists from Trinity College Dublin have unearthed a “universal thermal performance curve” (UTPC) that seemingly applies to all species and dictates their responses to temperature change. This UTPC essentially “shackles evolution” as no species seem to have broken free from the constraints it imposes on  how temperature affects performance.

All living things are affected by temperature, but the newly discovered UTPC unifies tens of thousands of seemingly different curves that explain how well “species work” at different temperatures. And not only does the UTPC seem to apply to all species, but also to all measures of their performance with regard to temperature variation – whether you are measuring lizards running on a treadmill, sharks swimming in the ocean, or recording cell division rates in bacteria.

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.
