A New Approach to Efficient Optoelectronics, Inspired by the Human Eye

A recipe for energy efficiency: an optical sensor that also processes data. The transparent dome represents interactions between photons (red and green) and the nanoscale elements on the substrate. Carbon nanotubes with quantum dots (small spheres) are shown connected to CMOS circuitry below. (Credit: François Léonard/Sandia National Laboratories)

A nearby supernova could end the search for dark matter

An artist's concept of a highly magnetized neutron star. According to current theory, axions would be created in the hot interior of the neutron star. UC Berkeley astrophysicists say that the strong magnetic field of the star will transform these axions into gamma rays that can be detected from Earth, pinpointing the mass of the axion.

DESI 3D Map of the Universe named one of Time Magazine's 'Best Inventions of 2024'

DESI has made the largest 3D map of our universe to date. Earth is at the center of this thin slice of the full map. In the magnified section, it is easy to see the underlying structure of matter in our universe. Credit: Claire Lamman/DESI collaboration; custom colormap package by cmastro
