A new study from researchers at The University of Texas MD Anderson Cancer Center finds that, in healthy women, some breast cells that otherwise appear normal may contain chromosome abnormalities typically associated with invasive breast cancer. The findings question conventional thinking on the genetic origins of breast cancer, which could influence early cancer detection methods. The study, published today in Nature, discovered that at least 3% of normal cells from breast tissue in 49 healthy women contain a gain or loss of chromosomes, a condition known as aneuploidy, and that they expand and accumulate with age. This poses questions for our understanding of 鈥渘ormal鈥� tissues, according to principal investigator Nicholas Navin, Ph.D., chair of Systems Biology.

The pipe organ stands as a bastion in concert halls and church sanctuaries, and even when not in use, it affects the acoustical environment around it. Researchers performed a sine-sweep through loudspeakers facing the organ pipes and measured the response with a microphone at different positions. They verified experimentally that sympathetic resonance does occur in organ pipes during musical performances and speeches, and that the overall amplitude increases when the signal matches the resonance of one or more pipes.

A new Harvey L. Neiman Health Policy Institute study found non-physician practitioners鈥� (NPPs) share of imaging interpretation in office-based practices increased 117%, from 2.52% of Medicare imaging studies in 2013 to 5.47% in 2022. Interpretations by NPPs are performed by a small minority (5.55%) of NPPs with considerable variation by imaging modality and state.

A new study has discovered that siderophores, molecules produced by certain bacteria, are instrumental in the microbiome's defense against Ralstonia solanacearum, a pathogen causing severe crop losses. The research indicates that siderophores significantly boost the inhibitory effects of Pseudomonas strains on the pathogen, particularly under iron-limited conditions, offering a new avenue for developing eco-friendly disease control strategies in agriculture.
