A team of scientists from Chile and the United States discovered dozens of red cusk-eels, fish prized in Chilean seafood markets and celebrated in a poem by renowned Chilean poet Pablo Neruda, embedded in a bushy thicket of tubeworms at a methane seep off the coast of central Chile. This is the first time this commercially important species has been documented using methane seeps as habitat.

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.
