In an attempt to help students discuss challenging topics, researchers from the University of Exeter are to launch a new taster course for schools that teaches sex education through the examination and discussion of ancient artefacts. The Sex and History project will see youngsters aged between 14 and 19 discuss illustrations of objects from the collection of Sir Henry Wellcome.

October 14, A pair of neurons have been found in the brain of male nematode worms that allow them to remember and seek sex even at the expense of food. These neurons, which are male-specific, are required for sex-based differences in learning, suggesting that sex differences in cognitive abilities can be genetically hardwired.

Developmental genetic studies in Drosophila unraveled the importance of Polycomb group PcG and Trithorax group TrxG genes in controlling cellular identity. PcG and TrxG proteins form histone modifying complexes that catalyze repressive or activating histone modifications, respectively, and thus maintaining the expression status of homeotic genes. Human orthologs of PcG and TrxG genes are implicated in tumorigenesis as well as in determining the prognosis of individual cancers.

It is widely hypothesized that the evolution of female extra-pair reproduction in socially monogamous species reflects indirect genetic benefits to females. However, a critical prediction of this hypothesis, that extra-pair young EPY are fitter than within-pair young WPYhas rarely been rigorously tested. We used 18 years of data from free-living song sparrows, Melospiza melodiato test whether survival through major life-history stages differed between EPY and WPY maternal half-siblings.
