New physical phenomenon on nanowires seen for the first time

Very tiny wires made of semiconducting materials – more than one thousand times thinner than a human hair – promise to be an essential component for the semiconductor industry. Thanks to these tiny nanostructures, scientists ...

Controlling lasers with dancing DNA

DNA is the hereditary material in the nucleus of all cells in humans and other living organisms. Besides its significance in biology, DNA has also played a specific role in controlling many physical devices. Recently, an ...

Twists and turns in interacting galaxies

(Phys.org)—Almost thirty years ago the Infrared Astronomy Satellite, IRAS, discovered that the universe contained many fabulously luminous galaxies, some of them more than a thousand times brighter than our own galaxy, ...

Abell 30: X-rays from a Reborn Planetary Nebula

(Phys.org)—These images of the planetary nebula Abell 30, (a.k.a. A30), show one of the clearest views ever obtained of a special phase of evolution for these objects. The inset image on the right is a close-up view of ...

Diamond color centers for nonlinear photonics

Researchers from the Department of Applied Physics at the University of Tsukuba demonstrated second-order nonlinear optical effects in diamonds by taking advantage of internal color center defects that break inversion symmetry ...

Very Large Telescope celebrates 15 years of success

(Phys.org) —With this new view of a spectacular stellar nursery ESO is celebrating 15 years of the Very Large Telescope—the world's most advanced optical instrument. This picture reveals thick clumps of dust silhouetted ...

Quasar jets confuse orbital telescope

Astrophysicists from the Moscow Institute of Physics and Technology, the Lebedev Physical Institute of the Russian Academy of Sciences (LPI RAS), and NASA have found an error in the coordinates of active galactic nuclei measured ...
