**"We present results from the analysis of cosmic microwave background (CMB), large scale structure (galaxy redshift survey) and X-ray galaxy cluster (baryon fraction and X-ray luminosity function) data, assuming a geometrically flat cosmological model and allowing for tensor components and a non-negligible neutrino mass. From a combined analysis of all data, assuming three degenerate neutrinos species, we measure a contribution of neutrinos to the energy density of the universe, Ω<sub>ν</sub>h<sup>2</sup> = 0.0059(+0.0033;−0.0027)(68 per cent confidence limits), with zero falling on the 99 per cent confidence limit. This corresponds to ~4 per cent of the total mass density of the Universe and implies a species-summed neutrino mass Σ<sub><i>i</i></sub><i>m</i><sub><i>i</i></sub> = 0.56(+0.30;−0.26)eV, or <i>m</i><sub><i>i</i></sub> = 0.2eV per neutrino." | **"We present results from the analysis of cosmic microwave background (CMB), large scale structure (galaxy redshift survey) and X-ray galaxy cluster (baryon fraction and X-ray luminosity function) data, assuming a geometrically flat cosmological model and allowing for tensor components and a non-negligible neutrino mass.

- "Neutrinos are no longer just a curiosity of physics but a practical tool for astronomy...Neutrinos will give astronomers a type of x-ray vision far better than actual x-rays. Being the most unreactive type of subatomic particle, they pass through intervening matter as though it were hardly there—revealing the cores of stars and other dramatic but otherwise hidden places in the cosmos."

From a combined analysis of all data, assuming three degenerate neutrinos species, we measure a contribution of neutrinos to the energy density of the universe, Ωνh2 = 0.0059(+0.0033;−0.0027)(68 per cent confidence limits), with zero falling on the 99 per cent confidence limit. This corresponds to ~4 per cent of the total mass density of the Universe and implies a species-summed neutrino mass Σimi = 0.56(+0.30;−0.26)eV, or mi = 0.2eV per neutrino."
