Previous research indicates that the scent of developmental stability (low fluctuating asymmetry, FA) is attractive to women who are fertile (at high-conception risk points in their menstrual cycles), but not other or men. Prior also dissimilarity major histocompatibility complex (MHC) genes may play a role human mate choice. We studied attractiveness opposite sex t-shirts worn for 2 nights' sleep.

The production and event topology of three-jet events produced in p¯p collisions at √s=1.8 TeV have been studied with the Collider Detector Fermilab Tevatron Collider. distributions angular variables (ψ∗ cosθ∗) describing energy sharing between jets (x3 x4) are found to agree well tree-level QCD calculations. These predicted different shapes for initial-state subprocesses (quark-antiquark, quark-gluon, gluon-gluon). data consistent small expected contribution from quark-antiquark initial...
