Virginia Key, Fla. – In a paper published in the journal Science today, scientists Gabriel A. Vecchi of NOAA's Geophysical Fluid Dynamics Laboratory, Kyle L. Swanson of the University of Wisconsin - Milwaukee Atmospheric Sciences Group and Brian J. Soden from the University of Miami's Rosenstiel School of Marine and Atmospheric Science teamed up to study hurricane data observed over more than 50 years.

Oregon researchers have synthesized an elusive metal-hydroxide compound in sufficient and rapidly produced yields, potentially paving the way for improved precursor inks that could boost semiconductor capabilities for large-area applications.
The key to a "bottom-up" production of possibly the first heterometallic gallium-indium hydroxide nanocluster was the substitution of nitroso-butylamine as an additive in place of nitrosobenzene.
Dr. Paul Haridakis, associate professor of Communication Studies at Kent State University and a long-time scholar in the area of the impact of media on the political landscape in the U.S., is investigating the impact of hugely popular social media's impact on the upcoming presidential contest.
We have previously shown that E2 and P4 have clear and distinct effects on inflammatory response and gastric epithelial changes during early H. pylori infection. Recently, Ohtani et al., have shown a protective role of E2 administration in H. pylori-infected InGas mice. Other studies have demonstrated that E2 and P4 have anti-ulcerative effects in murine gastric mucosa. ER and PR have been reported in human, mouse and rat stomach. However, there is no information to date of their expression and regulation in Mongolian gerbil stomach.
COLUMBIA, Mo. – The 2008 presidential campaign, as reflected in candidates' television spots, has been one of the most negative campaigns in history. A University of Missouri professor analyzed this year's candidates' television spots, including last night's 30-minute ad by Sen. Barack Obama and found that only one other campaign matched this level of negativity.
CHAPEL HILL – A new study seeking to improve scientists' understanding of breast cancer, including why the disease's fatality rate is higher in African-American women, is getting underway in 44 counties in North Carolina.
The project, named after the late Jeanne Hopkins Lucas, a North Carolina state senator who died of breast cancer last year, is being run by the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill.
WASHINGTON, D.C. (Oct. 30, 2008) -- Next week marks a pivotal moment for Eastern Pacific tuna. The Inter-American Tropical Tuna Commission (IATTC), the international body charged with the conservation and management of tuna and associated species in the eastern tropical Pacific Ocean, will meet in San Diego from Nov. 2-7 to consider conservation measures for vulnerable tuna populations. Whether this 16-nation Commission will act to protect declining tuna stocks, or once again demonstrate their impotence to do so, remains to be seen. The fate of Pacific tuna stocks hangs in the balance.
GAINESVILLE, Fla. — Small islands dwarf large ones in archaeological importance, says a University of Florida researcher, who found that people who settled the Caribbean before Christopher Columbus preferred more minute pieces of land because they relied heavily on the sea.
What makes a great leader? Traits that we look for typically include a sense of power, great negotiating skills and lots of charisma. However, a recent study suggests that it is not just an outgoing personality and great communication skills that determine who is chosen as leader of a group. Previous research has implicated that there is a gender bias when selecting leaders; preference for a male versus female leader may depend on the specific situation that a group finds itself in. Psychologists Mark Van Vugt and Brian R.
It has been shown (and probably experienced by all of us) that performing worse than our peers on a particular task results in negative self-esteem and poorer subsequent performance on the same task. How people respond when their peers perform better than they do has been studied in a variety of age groups and it turns out that preschoolers have thicker skin than adults do! Previous research has shown that preschoolers (4-5 year old children) maintain positive self-evaluations and high levels of performance even when they see that their peers have out-performed them.
Scientists are on the hunt for evidence of antimatter - matter's arch nemesis – left over from the very early Universe. New results using data from NASA's Chandra X-ray Observatory and Compton Gamma Ray Observatory suggest the search may have just become even more difficult.
TALLAHASSEE, Fla. -- It's one of the coldest and most remote areas on Earth, but the Arctic region has long held great strategic interest for a number of nations. Now, a Florida State University researcher is leading an international team that is working to produce one of the most comprehensive histories to date of the northernmost part of the world from the late 19th century to the present.
CAMBRIDGE, Mass. — The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end a period of about a decade in which atmospheric levels of the potent greenhouse gas were essentially stable, according to a team led by MIT researchers.
PROVIDENCE, R.I. [Brown University] — Newspaper endorsements for presidential candidates can influence voting decisions, according to new research by two Brown University economists. In a working paper, Brian Knight and graduate student Chun Fang Chiang demonstrate that voters are more likely to support the recommended candidate following the publication of an endorsement, but any degree of influence depends on the credibility of the paper's pick.

Like something from a horror movie, the swarm of bacteria ripples purposefully toward their prey, devours it and moves on.
Researchers at the University of Iowa are studying this behavior in Myxococcus xanthus (M. xanthus), a bacterium commonly found in soil, which preys on other bacteria.
