Cometary Glycolaldehyde as a Source of pre-RNA Molecules.

Abstract: Over 200 molecules have been detected in multiple extraterrestrial environments, including glycolaldehyde (C2(H2O)2, GLA), a two-carbon sugar precursor that has been detected in regions of the interstellar medium. Its recent in situ detection on the nucleus of comet 67P/Churyumov-Gerasimenko and through remote observations in the comae of others provides tantalizing evidence that it is common on most (if not all) comets. Impact experiments conducted at the Experimental Impact Laboratory at NASA's Johnson Space Center have shown that samples of GLA and GLA mixed with montmorillonite clays can survive impact delivery in the pressure range of 4.5 to 25 GPa. Extrapolated to amounts of GLA observed on individual comets and assuming a monotonic impact rate in the first billion years of Solar System history, these experimental results show that up to 1023 kg of cometary GLA could have survived impact delivery, with substantial amounts of threose, erythrose, glycolic acid, and ethylene glycol also produced or delivered. Importantly, independent of the profile of the impact flux in the early Solar System, comet delivery of GLA would have provided (and may continue to provide) a reservoir of starting material for the formose reaction (to form ribose) and the Strecker reaction (to form amino acids). Thus, comets may have been important delivery vehicles for starting molecules necessary for life as we know it.

Subpersonalities: Who Conducts the Orchestra?

Abstract: The theory of subpersonalities is a rapidly emerging theory of personality. In this article, the author offers a critique of the theory and urges that it be viewed and developed within the context ...

A comparison of techniques for measuring hue appearance

Abstract: Three different techniques for the direct measurement of color appearance were studied. Color estimation proved superior both to color naming and to color setting. The results have defined one technique in generating a color metric.

Systems Alignment for Comprehensive Faculty Development in Liberal Arts Colleges.

Abstract: Using an alignment framework, the authors explore faculty development initiatives in liberal arts colleges in order to understand the connection between organizational priorities and processes as connected to faculty members’ stated needs. The study draws on mixed-methods data from The Initiative for Faculty Development in Liberal Arts Colleges (IFDLAC), including survey and interview data from the 13 member institutions of the Great Lakes Colleges Association (GLCA).The authors offer future implications for faculty development practice.

Escape and avoidance learning in the earthworm Eisenia hortensis

Abstract: Interest in instrumental learning in earthworms dates back to 1912 when Yerkes concluded that they can learn a spatial discrimination in a T-maze. Rosenkoetter and Boice determined in the 1970s that the “learning” that Yerkes observed was probably chemotaxis and not learning at all. We examined a different form of instrumental learning: the ability to learn both to escape and to avoid an aversive stimulus. Freely moving “master” worms could turn off an aversive white light by increasing their movement; the behavior of yoked controls had no effect on the light. We demonstrate that in as few as 12 trials the behavior of the master worms comes under the control of this contingency.
