The primary goal of the search for extraterrestrial intelligence is to gain an understanding of the prevalence of technologically advanced beings (organic or inorganic) in the Galaxy. One way to approach this is to look for technosignatures: remotely

Recent results in the effort to characterize the galactic population of extrasolar planets suggest that Earth-size planets in the habitable zone of their parent star may be numerous. This finding adds to a growing collection of evidence that the envi

Decreased activity of the rate limiting gluconeogenic enzyme, phosphoenolpyruvate carboxykinase (PEPCK), has been recently suggested to be the critical lesion in the acute toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). We now show that other
