New DESI Results Strengthen Hints That Dark Energy May Evolve

Alt text: A long-exposure image captures circular star trails above telescope domes illuminated in red light on a dark mountain. A golden glow on the horizon marks distant city lights. Caption: DESI maps distant objects to study dark energy. The instrument is installed on the Mayall Telescope, shown here beneath star trails.

Faint green glow tints the curved horizon.

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.
