2 Abstract. We present the rst results of an ongoing eeort to search for new species in the lunar atmosphere. We discuss our observations in terms of the degree to which atomic metal abundances in the lunar atmosphere are stoichiometric, that is, proportional to surface abundances (as the Na:K ratio is). Na and K are the only atmospheric constituents to have been observed from Earth, but Apollo...

To establish which meiosis genes are present in ciliates, and to look for clues as to which recombination pathways may be treaded by them, four genomes were inventoried for 11 meiosis-specific and 40 meiosis-related genes. We found that the set of meiosis genes shared by Tetrahymena thermophila, Paramecium tetraurelia, Ichthyophthirius multifiliis, and Oxytricha trifallax is consistent with the...

Using an international sample of 9-to 11-year olds (n = 5812), monitored by accelerometers, Chaput and his team found no relationship between lunar cycle and physical activ...
