History: Einstein was no lone genius.
Marcel Grossmann (left) and Michele Besso (right), university friends of Albert Einstein (centre), both made important contributions to general relativity.
Lesser-known and junior colleagues helped the great physicist to piece together his general theory of relativity, explain Michel Janssen and Jürgen Renn.

Device can theoretically trap a light ‘bit’ for an infinite amount of time
The optical meta-atom has a core (with radius R1) and shell (with radius R2). Light of a specific wavelength (quantized energy) can be trapped inside the core. Credit: Lannebère, et al. CC-BY-4.0

Fermi mission finds hints of gamma-ray cycle in an active galaxy
Astronomers using data from NASA’s Fermi Gamma-ray Space Telescope have detected hints of periodic changes in the brightness of a so-called “active” galaxy, whose emissions are powered by a supersized black hole. If confirmed, the discovery would mark the first years-long cyclic gamma-ray emission ever detected from any galaxy, which could provide new insights into physical processes near the black hole.

What every physicist should know about string theory
Some of nature’s rhymes—the appearance of similar structures in different areas of physics—underlie the way that string theory potentially unifies gravity with the other forces of nature and eliminates the ultraviolet divergences that plague quantum gravity.
