Discovery in parasite movement may offer insights into malaria

...uses. In addition, the organism is used as a model experimental system for studying the closely related mosquito-borne malaria parasite Plasmodium. "The way these organisms move and the way their movement is controlled is absolutely critical to their ability to cause disease," said Dr. Con Beckers, associate prof...

Stuart Lipton honored with Jung Prize for Medicine

Dr. Lipton shares this year's award with Prof. Dr. Tobias Bonheoffer of the Max-Planck-Institut fur Neurobiologie, Munich-Martinsried. The co-recipients each received 125,000 Euros from the Jung-Stiftung fur Wissenschaft und Forschung. ...

High Flux Isotope Reactor marks 400th cycle

...Science. New beam lines, which channel neutrons to experimental instruments, have been installed. A new experiment hall has been constructed, and a "cold source" is in preparation that literally chills the energetic neutrons, slowing them and making them more useful for studying polymers and biological materials....

Earth, sky tapped in unique global climate change study

...spent a year designing and building the elaborate, experimental system. Volder joined the team recently as the climate simulations and data collection began. The system includes eight giant shelters built to exclude rainfall but allow a free flow of air so as not to create greenhouse-like conditions. Under each ...

Chemical reaction in birds provides sense of direction during migratory flights

...authors of the paper, who developed the behavioral experimental setup used in the study for testing magnetic orientation in birds. During migratory unrest, the birds could move in their cages. Each cage was funnel-shaped, lined with coated paper and measured approximately 1.5 feet in diameter. When the birds move...

"But once in orbit we found both Proba and CHRIS performed well above expectations, and so we put out an Announcement of Opportunity for scientists ...

Catastrophic shift in species diversity and productivity of an ecosystem

... hard, critical look at this reigning view. In the experimental system, top predators instrumentally control species diversity and productivity of the ecosystem. This control comes about by causing herbivores to feed on and suppress the abundance of a highly productive plant that otherwise would out-compete many ...

JGI decodes wood & toxic waste-degrading fungus genome

...porium genome database now established provides an experimental framework to more fully understand this fundamental process," says Dan Cullen, research scientist with the USDA Forest Products Lab in Madison, Wisconsin, and another author on the paper. "The oxidative enzyme systems of P. chrysosporium not only deg...

Though little was known about it, a mouse homolog had been identified as a mitotic chromosome-associated protein. "It immediately jumped out at us that this could very well be the mitotic tether that we had been looking f...

Mexican farmers effectively cultivate phenotypic diversity in maize

Selection criteria are still a highly individual choice and depend on a number of factors. For instance taste, colour, and cooking quality ch...

Biological oceanographers examine 'regime shifts' in complex marine ecosystems

..., scope and interrelatedness of marine ecosystems, experimental manipulation is infeasible. Ecological theory and mathematical models are therefore essential tools for developing this understanding. Regime shifts can occur, for example, when changes in ocean conditions, such as warming, affect plankton productio...

UCSD finds genetic time bomb in heart that leads to heart failure in some patients
