# s-brain: stress, differences between the sexes

<< Men and women react differently to stress. Animal studies suggest the root of the difference is messaging within the brain >>

<< But until recently, studies of people’s responses to such stress have focused primarily on men >>

# s-chem: fuel from air

<< A highly efficient homogeneous catalyst system for the production of CH3OH from CO2 using pentaethylenehexamine and Ru-Macho-BH (1) at 125–165 °C in an ethereal solvent has been developed (initial turnover frequency = 70 h–1 at 145 °C) >>

<< Various sources of CO2 can be used for this reaction including air, despite its low CO2 concentration (400 ppm) >>

# s-pharma: about inflammation: aspirin vs reduced lethal prostate cancer

<< Among undiagnosed men who took regular aspirin, the risk of developing a lethal form of prostate cancer was reduced by 24 percent, and among those already diagnosed with the disease, regular aspirin use lowered their risk of dying from it by 39 percent >>
