Astrophysicists discover a quasar that acts as a cosmic lens (w/ Video)
contains nearly a million galaxies and over 120,000 quasars.
A sample of some 23,000 of these quasars in the northern hemisphere was selected by the Laboratory of Astrophysics team. In the end, only four of them seemed to act as a gravitational lens.

Heart of darkness could explain sun mysteries - New Scientist
Their simulations show that gravity would pull such dark particles to the centre of the sun, where they would absorb heat. Some of these dark matter particles would then carry this heat from the core to the surface, decreasing the core temperature

[1005.5102] Light WIMPs in the Sun: Constraints from Helioseismology
Our main conclusion demonstrates that both direct detection experiments and particle accelerators may be complemented by using the Sun as a probe for WIMP dark matter particles in the 5-50 GeV mass range.
