Capture of Galactic Dark Matter by the Solar System |
We have calculated the amount of galactic dark matter captured by the Solar System as a result of its gravitational scattering by the planets. Thus obtained local density of dark matter near the planets is compared with the observational upper limits. |

Does Cosmological Term Influence Gravitational Lensing? |
We analyze the bending of light by galaxies or clusters of galaxies in the presence of the $\La$ term. Going over to the Friedmann-Robertson-Walker (FRW) coordinates, used in fact for the description of actual observations, we demonstrate that the cosmological constant does not influence practically the lensing effect. |

Can one detect passage of small black hole through the Earth? |
The energy losses of a small black hole passing through the Earth are examined. In particular, we investigate the excitations in the frequency range accessible to modern acoustic detectors. The main contribution to the effect is given by the coherent sound radiation of the Cherenkov type. |
