| Hubble tells a tale of galactic collisions Posted: 12 May 2013 11:53 AM PDT When we look into the distant cosmos, the great majority of the objects we see are galaxies: immense gatherings of stars, planets, gas, dust, and dark matter, showing up in all kind of shapes. A new Hubble picture registers several, but the galaxy catalogued as 2MASX J05210136-2521450 stands out at a glance due to its interesting shape.  |
| Graphene joins the race to redefine the ampere Posted: 12 May 2013 11:12 AM PDT New research could pave the way for redefining the ampere in terms of fundamental constants of physics. The world's first graphene single-electron pump provides the speed of electron flow needed to create a new standard for electrical current based on electron charge.  |
| Nano-breakthrough: Solving the case of the herringbone crystal Posted: 12 May 2013 11:12 AM PDT Leading nanoscientists created beautiful, tiled patterns with flat nanocrystals, but they were left with a mystery: Why did some sets of crystals arrange themselves in an alternating, herringbone style? To find out, they turned to experts in computer simulation.  |
| Better dyes for imaging technology Posted: 12 May 2013 07:55 AM PDT From microscopes to MRI scanners, imaging technology is growing ever more vital in the world's hospitals, whether for the diagnosis of illness or for research into new cures. Imaging technology requires dyes or contrast agents of some sort. Current contrast agents and dyes are expensive, difficult to work with and far from ideal. Now, chemists have discovered a new dye and proved its worth against any of the dyes currently available.  |
| Highly fragile, volatile body observed with new quantum-mechanical measurement technique Posted: 05 May 2013 11:59 AM PDT Scientists have observed a highly fragile and volatile body through a new quantum-mechanical measurement technique.  |
