In a feat of quantum one-upmanship, two teams of scientists have staked new claims of linking whopping numbers of atoms at the quantum level. Researchers from Geneva demonstrated quantum entanglement of 16 million atoms, smashing the previous record of about 3,000 entangled...
How does a galaxy like our own Milky Way form? Until now there’s been a lot of inferring involved in answering that question. The basic story is that gas collects toward the center of roughly spherical “halos” of matter.
Conventional fluids flow only in response to external forces, but scientists are increasingly interested in "active matter" that consumes energy and moves itself. Previously, this has been seen only on millimeter or centimeter scales, but now researchers in the U.S. have...
Astronomers using the Hubble Space Telescope have spotted a supermassive black hole that has been propelled out of the centre of the galaxy where it formed. They reckon the huge object was created when two galaxies merged and was then ejected by gravitational waves.
Thirty years ago, a professor in Japan folded an origami crane smaller than a pinhead. Peering through a microscope, he used a sewing needle to carefully crimp the paper. Now researchers at Cornell University in Ithaca, New York, have gone one step further, creating origami...
When we look out at the luminous matter in the Universe -- stars, galaxies, clusters of galaxies and the hot gas in and between them -- it tells a couple of different stories. One is the story of how normal matter (based...
