# New studies document PFAS breast cancer risk, tick infection mechanics, oarfish locomotion

Three separate research teams published peer reviewed findings in medical and biological journals.

A study published in the Journal of Clinical Oncology found women with higher blood levels of PFOA and PFOS had 67% and 93% higher rates of ER-negative breast cancer, respectively. [^1]

ER-negative breast cancers are more aggressive and have worse outcomes compared to estrogen-responsive breast cancers, according to the U.S. Department of Health and Human Services. [^2]

Chanakan Suwanbongkot, Ph.D., published findings from her dissertation research in the journal PLOS Pathogens, advancing understanding of how tick-borne bacteria enter the body and interact with the immune system. [^3]

Gulf Coast ticks transmit Rickettsia parkeri within one hour of attachment before spreading to lymph nodes and internal tissues. [^4]

A research team published a study on oarfish locomotion mechanics in the peer-reviewed journal BioOne on 2026-09-30. [^5]

Each oarfish dorsal fin ray is controlled by six muscles attached at 12 points, via a ball-and-socket joint allowing full 360 degree rotation. [^6]

The oarfish propels itself efficiently and silently by undulating its full-length dorsal fin while keeping its main body rigid. [^7]
