AbstractMillimetre-band scans of the frequency space towards optically dim quasars is potentially a highly efficient method for detecting new high red-shift molecular absorption systems. Here we describe scans towards 7 quasars over wide bandwidths (up to 23 GHz) with sensitivity limits sufficient to detect the 4 redshifted absorbers already known. With wider frequency bands, highly efficient searches of large numbers of possibly obscured objects will yield many new molecular absorbers.

A device that uses fluorescent powder to automatically mark large numbers of honeybees provides a good method to distinguish focal colony foragers from foragers of other colonies. However, when humidity is high, the powder readily forms pellets that cannot pass through the mesh and marking is diminished. We present here an apparatus to mass-mark honeybees with liquid paint. We demonstrate that this low-cost device is a highly efficient method to mark honeybees and does not produce any observable mortality on test foragers or impairing flight ability.
