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 has discovered iron-60 in Antarctic snow for the first time. The scientists suggest that the iron isotope comes from the interstellar neighborhood.

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.
