The rare isotope iron-60 is created in massive stellar explosions. Only a very small amount of this isotope reaches the earth from distant stars. Now, a research team with significant involvement from the Technical University of Munich (TUM) has discovered iron-60 in Antarctic snow for the first time. The scientists suggest that the iron isotope comes from the interstellar neighborhood.

Japanese researchers show how a holographic tabletop experiment can be used to simulate the physics of a black hole. This work may lead the way to a more complete theory of quantum gravity that harmonizes quantum mechanics and relativity.

Lithium fluoride crystals have recently been used to register the tracks of nuclear particles. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow have just demonstrated that these crystals are also ideal for detecting tracks of high-energy ions of elements even as heavy as iron.

An experiment to test a popular theory of dark energy has found no evidence of new forces, placing strong constraints on related theories.

Physicists from HKUST and PKU have successfully created the world's first 3D simulation of topological matter consisting of ultracold atoms.

Researchers at the University of Illinois at Urbana-Champaign, collaborating with scientists at the SLAC National Accelerator Laboratory, have shed new light on how superconductivity and charge order can exist adjacent to one another.

an international team of researchers, including scientists from the Department of Energy's SLAC National Accelerator Laboratory, has demonstrated a potentially much brighter electron source based on plasma that could be used in more compact, more powerful particle accelerators.

In a new study, Yale postdoctoral associate Nir Mandelker and professor Frank C. van den Bosch report on the most detailed simulation ever of a large patch of the intergalactic medium (IGM). For the first time, they were able to see how cold, dense gas clouds in the IGM organize themselves and react within much larger 'sheets' or 'pancakes' of matter in the vastness of space.
