Timing is everything: Bacterial attachment mimics just-in-time industrial model

ScienceDaily (Nov. 30, 2011) — n the human world of manufacturing, many companies are now applying an on-demand, just-in-time strategy to conserve resources, reduce costs and promote production of goods precisely when and where they are most needed. A recent study from Indiana University Bloomington scientists reveals that bacteria have evolved a similar just-in-time strategy to constrain production of an extremely sticky cement to exactly the appropriate time and place, avoiding wasteful and problematic...

More accurate tropical cyclone prediction model developed

ScienceDaily (Nov. 18, 2011) — Researchers at the Naval Research Laboratory Marine Meteorology Division (MMD), Monterey, Calif., have developed the Coupled Ocean/Atmosphere Mesoscale Prediction System Tropical Cyclone (COAMPS-TC™) model, achieving a significant research milestone in predictions of tropical cyclone intensity and structure.While the predictions of the paths or tracks of hurricanes, more generally referred to as tropical cyclones (TC), have steadily improved over the last few decades,...

Yeast model connects Alzheimer's disease risk and amyloid beta toxicity

ScienceDaily (Oct. 27, 2011) — In a development that sheds new light on the pathology of Alzheimer's disease (AD), a team of Whitehead Institute scientists has identified connections between genetic risk factors for the disease and the effects of a peptide toxic to nerve cells in the brains of AD patients.The scientists, working in and in collaboration with the lab of Whitehead Member Susan Lindquist, established these previously unknown links in an unexpected way. They used a very simple cell...
