Three-star performance

Article Abstract:

Italian astronomers used tomographic data to observe light from three outer stars to determine how light was deformed from the central star. Multiconjugate adaptive optic techniques used lights from several stars or lasers to produce three-dimensional maps of atmospheric turbulence known commonly as twinkling stars.

A glimpse of supersolid

Article Abstract:

Physicist Moses Chan and Eun-Seong Kim at Pennsylvania State University observed the behavior in helium 4 that was compressed to near absolute zero and its rotational inertia decrease. Supporting the idea of condensation, the two researchers did not observe superfluidity in solid helium 3, an isotope of helium that as a liquid undergoes a kind of condensation and becomes superfluid only at temperatures far below that needed by liquid helium 4.

A hint of axions

Article Abstract:

The laboratory made axions assumed to arrive from sun, as a result of big bang which were detected for the first time by an experiment in Italy known as polarization of the vacuum with a laser (PVLAS) is presented. The results from other observations contradict and rule out a large path of possible masses and interaction strengths and argue that if axions interact as strongly as PVLAS indicates, they could be produced in large quantities in stars, causing stars to grow old much faster than they are known to.
