Work in attosecond physics has led to a better understanding of how electrons move around. Oselote/iStock via Getty ImagesA group of three researchers earned the 2023 Nobel Prize in physics for work that has revolutionized how scientists study the electron – by illuminating molecules with attosecond-long flashes of light. But how long is an attosecond, and what can these infinitesimally short pulses tell researchers about the nature of matter? I first learned of this area of research as a gradua

Designing Less Addictive Opioids, Through Chemistry Please share this article - Go to very top of page, right hand side, for social media buttons. Opioids are one of the most powerful pain medications available, but millions of Americans have struggled with prescription opioid misuse after getting hooked on the feelings of calm and euphoria they also induce. But new research suggests there may be a way to chemically tailor opioids to reduce their addictive potential. The first wave of the opioid epidemic in the United States began in the 1990s. By 2015, approximately 11.5 million Americans we...
