Average smartphone users are willing to pay up to $5 extra for a typical application—or “app”—that won’t monitor their locations, contact lists and other personal information, a study conducted by two economists at the University of Colorado Boulder has found.
The researchers believe theirs is the first economic study to gauge the monetary value smartphone users place on privacy. That value is measured in consumers’ “willingness to pay” for five different kinds of digital anonymity. (more…)
American megachurches use stagecraft, sensory pageantry, charismatic leadership and an upbeat, unchallenging vision of Christianity to provide their congregants with a powerful emotional religious experience, according to research from the University of Washington.
“The megachurches movement is one of the leading indicators of how American Christians exercise their faith these days, so therefore they should be understood,” said James Wellman, associate professor of American religion at the University of Washington. “And our study shows they’re doing a pretty effective job for their members, based on self-reports, contrary to public opinion that tends to pass them off as a type of consumerist religion. In fact, their members speak eloquently of their spiritual growth.” (more…)
The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter recorded a scene on Jan. 29, 2012, that includes the first color image from orbit showing the three-petal lander of NASA’s Mars Exploration Rover Spirit mission. Spirit drove off that lander platform in January 2004 and spent most of its six-year working life in a range of hills about two miles to the east.
Another recent image from HiRISE, taken on Jan. 26, 2012, shows NASA’s Phoenix Mars Lander and its surroundings on far-northern Mars after that spacecraft’s second Martian arctic winter. Phoenix exceeded its planned mission life in 2008, ending its work as solar energy waned during approach of its first Mars winter. (more…)
Summertime hail could all but disappear from the eastern flank of Colorado’s Rocky Mountains by 2070, says a new study by the National Oceanic and Atmospheric Administration, the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences and the National Center for Atmospheric Research.
Less hail damage could be good news for gardeners and farmers, said lead author Kelly Mahoney, a research scientist at CIRES, but a shift from hail to rain can also mean more runoff, which could raise the risk of flash floods. “In this region of elevated terrain, hail may lessen the risk of flooding because it takes awhile to melt,” Mahoney said. “Decision makers may not want to count on that in the future.” (more…)
PASADENA, Calif. — NASA’s twin spacecraft to study the moon from crust to core are nearing their New Year’s Eve and New Year’s Day main-engine burns to place the duo in lunar orbit.
Named Gravity Recovery And Interior Laboratory (GRAIL), the spacecraft are scheduled to be placed in orbit beginning at 1:21 p.m. PST (4:21 p.m. EST) for GRAIL-A on Dec. 31, and 2:05 p.m. PST (5:05 p.m. EST) for GRAIL-B the next day. (more…)
NASA’s Mars Exploration Rover Opportunity has nearly completed its three-month examination of a crater informally named “Santa Maria,” but before the rover resumes its overland trek, an orbiting camera has provided a color image of Opportunity beside Santa Maria.
The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter acquired the image on March 1, while Opportunity was extending its robotic arm to take close-up photos of a rock called “Ruiz Garcia.” From orbit, the tracks Opportunity made as it approached the crater from the west are clearly visible. Santa Maria crater is about 90 meters (295 feet) in diameter. (more…)
PASADENA, Calif. — NASA’s Stardust spacecraft returned new images of a comet showing a scar resulting from the 2005 Deep Impact mission. The images also showed the comet has a fragile and weak nucleus.
The spacecraft made its closest approach to comet Tempel 1 on Monday, Feb. 14, at 8:40 p.m. PST (11:40 p.m. EST) at a distance of approximately 178 kilometers (111 miles). Stardust took 72 high-resolution images of the comet. It also accumulated 468 kilobytes of data about the dust in its coma, the cloud that is a comet’s atmosphere. The craft is on its second mission of exploration called Stardust-NExT, having completed its prime mission collecting cometary particles and returning them to Earth in 2006. (more…)
Children as young as age 2 are seeing more fast food ads than ever before, and restaurants rarely offer parents the healthy kids’ meal choices, according to a new study from Yale’s Rudd Center for Food Policy & Obesity. The new evaluation, the most comprehensive study of fast food nutrition and marketing ever conducted, shows that fast food marketers target children across a variety of media and in restaurants. In addition, the study finds that restaurants provide largely unhealthy defaults for the side dishes and drinks that come with kids’ meals. The detailed findings of this study will be presented in Denver today during the American Public Health Association’s annual meeting. (more…)
