“This is a long-standing, really neat experimental idea,” says Paul Lett, of the National Institute of Standards and Technology in GaithersburgLett, “Now we have to see whether or not it will lead to something practical, or will remain just a clever demonstration of quantum mechanics.”(CreditBarreto-Lemos, Vergano)

The Borexino neutrino detector uses a sphere filled with liquid scintillator that emits light when excited. This inner vessel is surrounded by layers of shielding and by about 2,000 photomultiplier tubes to detect the light flashes.(Credit: Borexino Collaboration)

MOLECULAR MODEL In the molecular model, quark-antiquark pairs form two color-neutral mesons that become weakly linked as a molecule.DIQUARK MODEL The particles form quark-quark and antiquark-antiquark pairs, which are forced to combine to balance their color charges.

A computer model shows one scenario for how light is spread through the early universe on vast scales (more than 50 million light years across). Astronomers will soon know whether or not these kinds of computer models give an accurate portrayal of light in the real cosmos. (Credit: Andrew Pontzen/Fabio Governato)

. A novel class of electronic materials – the so-called transition-metal oxides – hold promise for exciting, new applications. Where layers of this novel class of electronic materials touch, often a unique, and unprecedented phenomenon occurs: for instance, the interface between two insulators can become superconducting, or a strong magnetic order can build up between two non-magnetic layers.

WISE thermal-infrared images of (29075) 1950 DA. The image scale is 2.75 arcsec per pixel for the W1, W2 and W3 bands and 5.53 arcsec per pixel for the W4 band. White pixels are ‘bad’ pixels that do not contain data. The object seen in the red circle is (29075) 1950 DA. (Credit: Rozitis, MacLennan, Emery)

Experimental arrangement. A tip is approached to a distance of micrometres from a grounded highly ordered pyrolytic graphene (HOPG) surface carrying Ag nanostructures (illustrated in the inset). Electrons are field-emitted from the tip when a negative tip voltage Vt of hundreds of volts is applied, and the surface plasmon resonance (SPR) of the Ag nanostructures is excited by the field-emitted electrons under a strong electric field introduced by the tip–sample bias. The backscattered electrons are collected and analysed by the TEEA. (Credit: Nature Physics (2014) doi:10.1038/nphys3051)

Because of that alacrity, and the fact that they had repeat observations at roughly a decade’s detach, the Russian scientists were able to single out stars that dimmed by at least tenfold. They’ve been named 1RXS J114727.1 + 494302, 1RXS J130547.2 + 641252, and 1RXS J235424.5-102053. (Credit: Davies, NASA)

Mapping signals on the sky can offer clues about where the signals originate. Pulsars (top) concentrate in the Milky Way, because most of the ones we see sit in our galaxy. Gamma bursts (middle) come from everywhere, which means they’re parked in other galaxies. Fast radio bursts (bottom) seem to mostly avoid our galgaxy, a hint that they may come from very far away.(Credits: Green Bank Telescope, West Virginia Univ; G. Fishman et al/BATSE, CGRO, NASA.; J.

What is the view of time that Albert Einstein presents to us in special relativity? Einstein tells us that there is no separate ‘time’ or ‘space.’ ‘Time’ and ‘space’ cannot be separated; they are a united whole.
