Ununbium
(Preview)
Researchers are normally hard-pressed to catch a fleeting glimpse of the so-called superheavy elements at the far edge of the periodic table. Now a team has gone a step further and studied the chemistry of short-lived element 112, which seems to bond with other elements in the same way as its mundane...

Benford's law
(Preview)
What do earthquakes, spinning stellar remnants, bright space objects and a host of other natural phenomena have in common? Some of their properties conform to a curious and little known mathematical law, which could now find new uses. A subject of fascination to mathematicians, Benford's law sta...

Element 115
(Preview)
Two super heavy elements discovered
For the first time a Swiss research group has participated in the discovery of new chemical elements. The elements have the numbers 113 and 115 and were discovered by a combination of physical and chemical techniques in the Russian nuclear research...

Zc(3900)
(Preview)
First particle containing four quarks is confirmed. Physicists have resurrected a particle that may have existed in the first hot moments after the Big Bang. Arcanely called Zc(3900), it is the first confirmed particle made of four quarks, the building blocks of much of the Universes matter. Unti...

Atoms
(Preview)
It has long been known that it is possible to confine electrons or atoms in atomic structures in the same way as sheep can be shut in a pen. Physicists at the Max Planck Institute for Microstructure Physics in Halle have now discovered a strange thing: if the atomic fences have the right shape and the sub...

Osram LED
(Preview)
Osram has developed the world’s brightest white light-emitting diode. Known as Ostar Lighting, this LED supplies 200 lumens, thus literally putting light bulbs and neon lamps in the shade. Previously, the brightest LED from the Siemens subsidiary Osram had an output of 120 lumens. As far as its lu...

Title: What is the entropy of the universe? Authors: Paul Frampton, Stephen D.H. Hsu, Thomas W. Kephart, David Reeb Standard calculations suggest that the entropy of the universe is dominated by black holes, although they comprise only a tiny fraction of its total energy. We give a physical interp...
