Drifter or homebody? Study first to show where whitespotted eagle rays roam
It's made for long-distance travel, yet movement patterns of the whitespotted eagle ray remain a mystery. Between 2016 and 2018, scientists fitted 54 rays with acoustic transmitters and tracked them along both the Gulf of Mexico and Atlantic coasts of Florida, which differ in environmental characteristics. Results of the study reveal striking differences in travel patterns on the Atlantic coast compared to the Gulf coast and findings have significant conservation and adaptive management implications for this protected species.

Cancer-sniffing dogs 97% accurate in identifying lung cancer, according to study in JAOA
The next step will be to further fractionate the samples based on chemical and physical properties, presenting them back to the dogs until the specific biomarkers for each cancer are identified. The goal is to develop an over-the-counter screening product, similar to a pregnancy test, in terms of cost, simplicity and availability. Dr. Quinn envisions a device that someone can breathe into and see a color change to indicate a positive or negative finding. (2019-06-17)
