Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
New research by astronomers at the University of Utah and the Harvard-Smithsonian Center for Astrophysics (CfA) shows that supermassive black holes can grow…
Using very long observations of Cassiopeia A (or Cas A), a team of scientists has mapped the distribution elements in the supernova remnant in unprecedented…
In a paper published in the March 29 issue of the journal Nature, the scientists describe the emergence of “spontaneous coherence,” “spin textures” and “phase…
Some people like company. Others prefer to be alone. The same holds true for the particles that constitute the matter around us: Some, called bosons, like to…
When stars and their orbiting plants wander too close to the supermassive black hole at the center of the Milky Way, their encounter with the black hole's…

Periodontal disease, edentulism (tooth loss), cysts and malignant tumors are some of the major causes of bone loss in the periodontium. For these patients a…
By aiming high- and low-frequency laser beams at a semiconductor, the researchers caused electrons to be ripped from their cores, accelerated, and then smashed…
Active optical fibers with silicon photonic chips can carry a lot more information for data interconnect than copper cables. Silicon photonics can also be the…
Scientists created the colour picture by combining infrared light images from telescopes in the northern and southern hemispheres. Large structures of the…
