The 'Atomic Photon Source' consists of a planar Ag/amorphous SiOx/Pt junction with optical antennas, emitting light during electrical connection formation.
A cohort study of nearly 1,000 pregnant persons in NYC found that neighborhoods most affected by racism and economic inequality had higher rates of COVID-19 infection and preterm births. The researchers linked structural racism and community unemployment to increased risk of preterm birth.
Researchers mapped living corals in Hawaii before and after a mass bleaching event, discovering 'winners' that thrive in cleaner waters with less coastal development. The study found coral reefs near heavily developed coasts are more susceptible to mortality during heat waves, highlighting the need for targeted conservation efforts.
