GAINESVILLE, Fla. — A new study co-authored by University of Florida researchers provides details on the first cookiecutter shark attack on a live human, a concern as warm summer waters attract more people to the ocean. (more…)
*Smartphones Reach Key Milestone; Now Owned by 1 in 3 Americans*
RESTON, VA, July 5, 2011 – comScore, Inc., a leader in measuring the digital world, today released data from the comScore 
MobiLens service, reporting key trends in the U.S. mobile phone industry during the three month average period ending May 2011. The study surveyed more than 30,000 U.S. mobile subscribers and found Samsung to be the top handset manufacturer overall with 24.8 percent market share. Google Android led among smartphone platforms with 38.1 percent market share.
OEM Market Share
For the three month average period ending in May, 234 million Americans ages 13 and older used mobile devices. Device manufacturer Samsung ranked as the top OEM with 24.8 percent of U.S. mobile subscribers, followed by LG with 21.1 percent share and Motorola with 15.1 percent share. Apple strengthened its position at #4 with 8.7 percent share of mobile subscribers (up 1.2 percentage points), while RIM rounded out the top five with 8.1 percent share. (more…)
*Three friends are sailing the U.S. Eastern Seaboard in search of the American spirit. They’ve chronicled their journey and stayed connected with help from Office 365, an official sponsor of the trip.*
BOSTON – July 5, 2011 – In 1987, John Mirassou and two friends set sail from Ft. Lauderdale on a 17-foot Boston Whaler. They didn’t expect to find anything more than good times on their journey, which ultimately logged some 6,100 miles. They were wrong.
“What started out as way to see the country by boat really turned into a story about the American people,” Mirassou said. “Everywhere we went we were taken in by people we had never met. This American spirit came out in amazing instances of generosity.” (more…)
*MU meteorologists say weather played a key role in union defeat*
COLUMBIA, Mo. — One hundred fifty years ago, two armies battled each other and the weather in Missouri’s first significant Civil War battle. While the battle’s course is familiar to historians, virtually no scientific data exists about the atmospheric conditions that influenced the fighting. In a project that blends history, sleuthing and modern weather analysis, Tony Lupo, professor and chair of the Department of Atmospheric Sciences at the University of Missouri, and Mike Madden, a meteorology student, have scientifically examined the heavy rains that hampered the union forces, eventually leading to a costly defeat.

Woods Hole Oceanographic Institution (WHOI) researchers have filled an important gap in the study of tunicate evolution by genetically sequencing 40 new specimens of thaliaceans, gelatinous, free-swimming types of tunicates. Their study was featured on the cover of the June issue of the Journal of Plankton Research.
Tunicates are a phylum of animals closely related to vertebrates, with a firm, rubbery outer covering called a tunic, from which the name derives. (more…)
The sun and the solar system’s rocky inner planets, including the Earth, may have formed differently than previously thought, according to UCLA scientists and colleagues analyzing samples returned by NASA’s Genesis mission.
The data from Genesis, which collected material from the solar wind blowing from the sun, reveal differences between the sun and planets with regard to oxygen and nitrogen, two of the most abundant elements in our solar system, the researchers report in two studies in the June 24 issue of the journal Science. And although the differences are slight, the research could help determine how our solar system evolved. (more…)
Nuclear power is a major component of our nation’s long-term clean-energy future, but the technology has come under increased scrutiny in the wake of Japan’s recent Fukushima disaster. Indeed, many nations have called for checks and “stress tests” to ensure nuclear plants are operating safely.
In the United States, about 20 percent of our electricity and almost 70 percent of the electricity from emission-free sources, including renewable technologies and hydroelectric power plants, is supplied by nuclear power. Along with power generation, many of the world’s nuclear facilities are used for research, materials testing, or the production of radioisotopes for the medical industry. The service life of structural and functional material components in these facilities is therefore crucial for ensuring reliable operation and safety. (more…)
ANN ARBOR, Mich.—In type 2 diabetes, a protein called amylin forms dense clumps that shut down insulin-producing cells, wreaking havoc on the control of blood sugar. But zinc has a knack for preventing amylin from misbehaving.
Recent research at the University of Michigan offers new details about how zinc performs this “security guard” function. The findings appear in the July 8 issue of the Journal of Molecular Biology. (more…)
