B-mode polarisation
(Preview)
Title: The Superhorizon Test of Future B-mode Experiments Author: Hayden Lee, S.-C. Su, Daniel Baumann Inflation predicts B-mode polarisation with correlations that span superhorizon scales at recombination. In contrast, the correlations set up by causal sources, such as phase transitions...

The Antares telescope takes its first look at the heavens
The first detection line of the Antares neutrino telescope, lying under 2,500 meters of water, was connected by Ifremer's remotely operated robot Victor 6000 to the onshore station at La Seyne-sur-Mer (Var) on Thursday 2 March at 12:11...

Holometer
(Preview)
Do we live in a 2-D hologram? A unique experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory called the Holometer has started collecting data that will answer some mind-bending questions about our universe - including whether we live in a hologram. Much like charact...

PandaX
(Preview)
China launches world's deepest particle-physics experiment - but it joins a crowded field. Ongoing dark matter experiments in Italy, the United States and Japan are now being joined by a fourth in China, called PandaX. Installed in the deepest laboratory in the world, 2,500 metres under the marbl...

Darkest Material
(Preview)
The "darkest ever" substance known to science has been made in a US laboratory. The material was created from carbon nanotubes - sheets of carbon just one atom thick rolled up into cylinders. Researchers say it is the closest thing yet to the ideal black material, which absorbs light perf...

Tungsten
(Preview)
As the filament in an incandescent light bulb, tungsten can illuminate a room, but it hasn't been spotlighted as an environmental contaminant in the same way that lead or mercury has. In fact, in the mid-1990s, believing that tungsten is relatively insoluble in water and nontoxic, the Army replace...

MicroBooNE dectector
(Preview)
Massive 30-ton MicroBooNE particle detector moved into place, will see neutrinos this year On Monday, June 23, the next phase of neutrino physics at Fermilab fell (gently) into place. The MicroBooNE dectector - a 30-ton, 40-foot-long cylindrical metal tank designed to detect ghostly particle...

Element 117
(Preview)
Scientists Discover Heavy New Element A team of Russian and American scientists has discovered a new element that has long stood as a missing link among the heaviest bits of atomic matter ever produced. The element, still nameless, appears to point the way toward a brew of still more massive element...

Virtual Particles
(

)
(Preview)
Any vibrating object should be slowed by quantum "virtual" particles that permeate empty space, according to theory. This weak "friction" should spew photons like sparks from a dangling bumper. In the 26 May PRL researchers propose detecting this effect by vibrating one end of a small reflective...

Oklo Natural Nuclear Reactor
(Preview)
In May 1972 a worker at a nuclear fuelprocessing plant in France noticed something suspicious. He had been conducting a routine analysis of uranium derived from a seemingly ordinary source of ore. As is the case with all natural uranium, the material under study contained three isotopes - that is to...

Carbon-14 decay

Researchers studying the labyrinthine nature of atomic nuclei say they have answered a question that has puzzled physicists for more than half a century: Why does the radioactive isotope known as carbon-14 decay so slowly? The discovery could lead to a better understanding of the workings of the s...
