GAINESVILLE, Fla. — By analyzing the genes of bacteria, University of Florida researchers have moved a step closer to pinpointing how two brain disorders common in small-breed dogs occur.
The researchers found that the bacteria, known as Mycoplasma canis, invade dog’s cells and suppress their immune system responses. (more…)
International team of scientists finds adaptations to stress in oyster genome
When it comes to stress, oysters know how to deal. The tough-shelled mollusks can survive temperature fluctuations, toxic metals and exposure to air, and a new study of their genetic makeup is helping to explain how.
An international team of scientists, including the University of Delaware’s Patrick M. Gaffney, professor of marine biosciences, sequenced the genome of the Pacific oyster, Crassostrea gigas, in a Nature paper published on Sept. 19. (more…)
EAST LANSING, Mich. — A team of researchers at Michigan State University has documented the step-by-step process in which organisms evolve new functions.
The results, published in the current issue of Nature, are revealed through an in-depth, genomics-based analysis that decodes how E. coli bacteria figured out how to supplement a traditional diet of glucose with an extra course of citrate. (more…)
Analysis of data from the National Science Foundation’s South Pole Telescope, for the first time, more precisely defines the period of cosmological evolution when the first stars and galaxies formed and gradually illuminated the universe. The data indicate that this period, called the epoch of reionization, was shorter than theorists speculated — and that it ended early.
“We find that the epoch of reionization lasted less than 500 million years and began when the universe was at least 250 million years old,” said Oliver Zahn, a postdoctoral fellow at the Berkeley Center for Cosmological Physics at the University of California, Berkeley, who led the study. “Before this measurement, scientists believed that reionization lasted 750 million years or longer, and had no evidence as to when reionization began.” (more…)
A University of Colorado analysis of state-by-state factors leading to the Electoral College selection of every U.S. president since 1980 forecasts that the 2012 winner will be Mitt Romney.
The key is the economy, say political science professors Kenneth Bickers of CU-Boulder and Michael Berry of CU Denver. Their prediction model stresses economic data from the 50 states and the District of Columbia, including both state and national unemployment figures as well as changes in real per capita income, among other factors.
“Based on our forecasting model, it becomes clear that the president is in electoral trouble,” said Bickers, also director of the CU in DC Internship Program. (more…)
A research team at the Georgia Tech Research Institute (GTRI) has developed a software tool that enables users to perform in-depth analysis of modeling and simulation data, then visualize the results onscreen. The new data analysis and visualization tool offers improved ease of use compared to similar tools, the researchers say, and could be readily adapted for use with existing data sets in a variety of disciplines.
The data analysis and visualization tool is a subset of the Test Matrix Tool (TMT), a multi-component system developed by GTRI for designing, executing and analyzing large-scale modeling and simulation data sets. The visualization capability offers a graphical user interface that provides both on-screen data-manipulation features like filters and the ability to see query results in the form of graphical images almost instantly.
