Harmful algal blooms (HABs) cause significant economic and ecological damage worldwide. Despite considerable efforts, a comprehensive understanding of the factors that promote these blooms has been lacking, because the biochemical pathways that facilitate their dominance relative to other phytoplankton within specific environments have not been identified.(More)
In a 6-month, double-blind, placebo-controlled study, 100 to 150 mg/d indomethacin appeared to protect mild to moderately impaired Alzheimer's disease patients from the degree of cognitive decline exhibited by a well-matched, placebo-treated group. Over a battery of cognitive tests, indomethacin patients improved 1.3% (+/- 1.8%), whereas placebo patients(More)
The repressor REST/NRSF restricts expression of a large set of genes to neurons by suppressing their expression in non-neural tissues. We find that REST repression involves two distinct repressor proteins. One of these, CoREST, interacts with the COOH-terminal repressor domain of REST (Andres, M. E., Burger, C., Peral-Rubio, M. J., Battaglioli, E.,(More)
The Mercury Laser Altimeter (MLA) is one of the payload science instruments on the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) mission, which launched on August 3, 2004. The altimeter will measure the round-trip time of flight of transmitted laser pulses reflected from the surface of the planet that, in combination with the(More)
Cyanobacteria blooms caused by species such as Microcystis have become commonplace in many freshwater ecosystems. Although phosphorus (P) typically limits the growth of freshwater phytoplankton populations, little is known regarding the molecular response of Microcystis to variation in P concentrations and sources. For this study, we examined genes involved(More)

Initial images of Venus's south pole by the Venus Express mission have shown the presence of a bright, highly variable vortex, similar to that at the planet's north pole. Using high-resolution infrared measurements of polar winds from the Venus Express Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) instrument, we show the vortex to have a(More)
Harmful algal blooms (HABs) caused by microalgae have become a serious threat to public health, tourism, fisheries, ecosystems, and economies around the world. Recent studies have indicated that some macroalgae may inhibit the growth of HABs-forming microalgae. The red macroalgae, Porphyra spp. (nori), are the most valuable maricultured seaweed with a(More)
