Study Finds People with Certain Blood Types Have Increased Risks of Heart Attack During Periods of High Air Pollution
Individuals who have A, B, or AB blood types have an elevated risk of having a heart attack during periods of significant air pollution, compared to those with the O blood type, according to new research from the Intermountain Medical Center Heart Institute and Brigham Young University.
The new study is unique in that it links increased risk of heart attack associated with small particulate pollution to increased risk of heart attack for people with certain blood types who have coronary artery disease.
Scripps Scientists Use Photomosaic Technology to Find Order in the Chaos of Coral Reefs
In a study published recently in Coral Reefs, scientists from Scripps Institution of Oceanography at UC San Diego created and analyzed detailed photomosaics of the coral reef at Palmyra Atoll, and made surprising discoveries around coral spatial ecology. The scientists, led by graduate student Clinton Edwards, canvassed more than 17,000 square feet of reef, and 44,008 coral colonies, taking more than 39,000 images that were then stitched together to create 3D photomosaics that encompassed the reef.
