Previous simulations of the Martian atmosphere have shown how topography acts to confine the low-level Hadley cell flow into intense jets on the eastern flanks of Tharsis and Syrtis Major. We now conduct detailed studies of these jets using the NASA Ames Mars general circulation model (MGCM). The structure of...
Mars Pathfinder successfully landed at Ares Vallis on July 4, 1997, deployed and navigated
a small rover about l00 m clockwise around the lander, and collected data from three science
instruments and ten technology experiments. The mission operated for three months and returned
2.3 Gbits of data, including over 16,500...
Despite potential advantages of rights-based management over competitive fisheries, there has been significant political resistance to rights-based management from many fishermen, which has slowed the
adoption of rights-based management. This paper explores the concept of voluntary transitions to rights-based
management, under which fishermen may choose between an allocated fishery (with...
SCOPE: Aim of the study was to identify and monitor metabolite markers of dry bean consumption
in parallel human and mouse studies that each had shown chemopreventive effects of dry
bean consumption on colorectal neoplasia risk.
METHODS and RESULTS: Using LC/mass spectroscopy ± ESI and GC/mass spectroscopy, serum
metabolites of...

During the Ice in Clouds Experiment–Layer Clouds (ICE-L), aged biomass-burning particles were identified within two orographic wave cloud regions over Wyoming using single-particle mass spectrometry and electron microscopy. Using a suite of instrumentation, particle chemistry was characterized in tandem with cloud microphysics. The aged biomass-burning particles comprised ~30%–40% by number...
Simulations with a Mars general circulation model (GCM) are used to perform idealized tracer transport experiments, which are analyzed to yield estimates of eddy mixing coefficients as well as “stratospheric” ventilation timescales for the zonal-mean circulation. The results indicate that relatively moderate values of the vertical eddy mixing coefficient, KZ...
Drosophila suzukii (Spotted Wing Drosophila) has recently become a serious invasive pest of fruit crops in the USA, Canada, and Europe, leading to substantial economic losses. D. suzukii is a direct pest, ovipositing directly into ripe or ripening fruits; in contrast, other Drosophilids utilize decaying or blemished fruits and are...
