P30: Are There Anxious Genes?

Anxiety comprises many clinical descriptions and phenotypes. A genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. Extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-HT) transporter (5-HTT) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. Complete genome-wide linkage s...

Martian clouds observed by Mars Global Surveyor Mars Orbiter Camera

[1] We have made daily global maps that cover both polar and equatorial regions of Mars for Ls 135 –360 and 0 –111 using the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) red and blue wide-angle swaths taken from May 1999 to January 2001. We study the seasonal distribution of condensate clouds and dust clouds during roughly 1 Martian year using these daily global maps. We present the dev...

Are there carbonate deposits in the Valles Marineris, Mars?

The thick sequences of layered deposits found in the Valles Marineris have recently been determined by S.S. Nedell, S.W. Squyres, and D.W. Andersen (1987, Icarus, 70, 409-441) to contain a minimum of approximately 10(5) km3 of material. We suggest that this material could be derived from the precipitation of 30 mbar of atmospheric CO2 as carbonates in lakes. As surface temperatures fell on Ma...

Carbon reservoirs on Mars: Constraints from Martian meteorites

Introduction: The search for life on Mars is a subject of enormous scientific and public interest; it is anticipated that remote missions to Mars over the coming few years will garner the requisite data that will allow the presence, or otherwise, of martian biological carbon to be determined. The only previous attempt to detect the presence of life in martian soil, made by instruments on the Vi...
