Josephson Vortices MIPT physicists have learned how to locally control Josephson vortices. The discovery can be used for quantum electronics superconducting devices and future quantum processors.  A few months ago, a team of researchers led by Louis Taillefer at the University of Sherbrooke measured the thermal Hall conductivity in several compounds of copper, oxygen and other elements that are also high-temperature superconductors known as 'cuprates.'  Now, a new study in the journal Nature by scientists from Spain, the U.S., China and Japan shows that superconductivity can be turned on or off with a small voltage change, increasing its usefulness for electronic devices.  Superconducting nanowires could be used as both targets and sensors for the direct detection of dark matter, physicists in Israel and the US have shown.  "We invoke a different theory, the self-interacting dark matter model or SIDM, to show that dark matter self-interactions thermalize the inner halo, which ties ordinary dark matter and dark matter distributions together so that they behave like a collective unit."  Technology proposed 30 years ago to search for dark matter is finally seeing the light.  They're looking for dark matter-the stuff that theoretically makes up a quarter of our universe.  Results from its first run indicate that XENON1T is the most sensitive dark matter detector on Earth.  Scientists at Johannes Gutenberg University Mainz (JGU) in Germany have now come up with a new theory on how dark matter may have been formed shortly after the origin of the universe.  Map of dark matter made from gravitational lensing measurements of 26 million galaxies in the Dark Energy Survey.  CfA astronomers Annalisa Pillepich and Lars Hernquist and their colleagues compared gravitationally distorted Hubble images of the galaxy cluster Abell 2744 and two other clusters with the results of computer simulations of dark matter haloes.
