The results were announced at the Flavor Physics and CP Violation conference in Vancouver, and have been submitted to Physical Review Letters.
Read article 'HAPPEx shows the proton is not so strange'
Two more rounds of data taken by the Hall A Proton Parity Experiment (HAPPEx) at the US Department of Energy's Jefferson Lab have provided the most precise constraint yet on nucleon strangeness.
Read article 'FLASH produces the shortest wavelength yet'
On 26 April, the vacuum-ultraviolet and soft X-ray free-electron laser (FEL) facility at DESY generated pulses at the shortest wavelength yet, using electron bunches supplied by the TESLA Test Facilit...
Read article 'Neutrinos provide new route to heavy elements in supernovae'
During their long lifetimes stars generate their energies by nuclear fusion in their interiors, which are generally accepted to be the breeding grounds for carbon and heavier elements.
