An international team of nuclear physicists has found strong evidence for the existence of nuclear supersymmetry, a theory that relates bosons, which have integer values of spin, and fermions, with ha...
Superconductivity happens when the charge carriers overcome their mutual repulsion and bind together into Cooper pairs. In low-temperature superconductors phonons – quantized vibrations of the c...

The image of G21.5-0.9, a supernova remnant which is 16,000 light years from Earth, shows a bright central source (the neutron star) with bright nebula and surrounded by a much larger diffuse cloud. T...
Most semiconductor lasers emit light from the edge of the active laser region. However, in the VSCEL geometry light is emitted from the top of the device. This can reduce the threshold current needed ...
The first evidence for the accelerating universe came from observations of distant supernovae. However, the data were also consistent with an open universe – a universe that would expand forever...
Brian DeMarco and Deborah Jin used a pair of magneto-optical traps to confine about 700000 atoms of potassium-40 at temperatures below 300 nanokelvin. This is about half of the degeneracy temperature ...
Only two other methods have previously been used to manufacture quantum dots: electron beam lithography and epitaxy. Lithography is a top down approach in which the beam defines the dot pattern, where...
In copper oxide each of the copper atoms is expected to bond with two oxygen atoms. According to some theories however, the copper atoms can covalently bond with each other. Such bonds – in whic...

Campbell left his position last Friday after a series of anonymous faxes was sent to officials at the Department of Energy (DOE) saying that he did not have a doctorate degree. Although Campbell finis...
Results presented at the International Europhysics Conference on High Energy Physics in mid-July provide strong hints that the Higgs boson, one of the holy grails of particle physics, is lurking just ...
