Tiny carrier molecules called nanoparticles are often attached to radiation-emitting atoms in advanced medical imaging systems such as positron emission tomography (PET). These nanoparticles, paired with the right radioactive partners, can emit their own distinctive and readily detectable radiation—often visible light, according to a study from Weill Cornell Medicine scientists.

For Susannah Calhoun, her differences are also her greatest strengths. As a congenital amputee, she was inspired to overcome the challenges she faced and pursue a future in science, an interest first sparked in high school and culminating in her PhD.
