Using health records, Stanford researchers developed an algorithm for scoring the risk of a stroke patient experiencing a heart condition known as atrial fibrillation, a major risk factor for a second stroke. One stroke is dangerous, and a second, even more so. One important risk factor for that perilous second stroke is an irregular heart beat called atrial fibrillation. If doctors could identify the stroke patients who are most likely to experience atrial fibrillation, they could start treatments that would help prevent a second stroke. But which stroke patients are at risk for the condition has been hard to predict without costly 24/7 monitoring forRead More →

For the first time ever, astronomers at The University of New Mexico say they’ve been able to observe and measure the orbital motion between two supermassive black holes hundreds of millions of light years from Earth – a discovery more than a decade in the making. UNM Department of Physics & Astronomy graduate student Karishma Bansal is the first-author on the paper, ‘Constraining the Orbit of the Supermassive Black Hole Binary 0402+379’, recently published in The Astrophysical Journal. She, along with UNM Professor Greg Taylor and colleagues at Stanford, the U.S. Naval Observatory and the Gemini Observatory, have been studying the interaction between these blackRead More →

For surfers, finding the “sweet spot,” the most powerful part of the wave, is part of the thrill and the challenge. Scripps Institution of Oceanography at the University of California postdoctoral researcher Nick Pizzo has found the exact location on the wave where a surfer gains the greatest speed to get the best ride. Published this month online in the Journal of Fluid Mechanics, Pizzo applied principles of physics at the ocean’s surface—where air and water meet—to study how energy is transferred from the underlying wave to a particle on the surface, in this case, a surfer. “Based upon the speed and geometry of theRead More →
