Virtual reality crowds produce real behavior insights

Science Daily - Tue, 08/07/2014 - 6:09pm
Scientists are advancing virtual reality technology in the service of studying the science of the swarm: how patterns of crowd movement emerge from individual behaviors. They have developed a wireless virtual reality system to study how pedestrians interact with each other and how those individual behaviors, in turn, generate patterns of crowd movement. It's an everyday experience for all kinds of animals including ants, birds, fish and people.

Here Comes the Panopticon: Insurance Companies

Slashdot - Tue, 08/07/2014 - 5:47pm
New submitter jbmartin6 writes: The Panopticon may be coming, but perhaps not how we think. Instead of a massive government surveillance program, we might end up subjected to ubiquitous monitoring to save on our insurance premiums. The "internet of things (you can't get away from)" makes this more and more possible. Here a company saved money on its health insurance premiums by distributing Fitbits and an online service to enable reporting fitness gains back to the insurance company. We've already seen the stories on using black boxes to monitor drivers. There is even an insurance company named Panoptic! Heck, why not a premium hike for owners of this or that "aggressiveness gene"? What if in the future we got a quick "+50 cents" tweet for every scoop of ice cream? I suppose the natural stopping point might be the balance between an individual's willingness to be monitored and the desire to reduce insurance premiums.

NASA-JAXA's new precipitation satellite sees first Atlantic hurricane

Science Daily - Tue, 08/07/2014 - 5:23pm
The Global Precipitation Measurement (GPM) Core Observatory flew over Hurricane Arthur five times between July 1 and July 5, 2014. Arthur is the first tropical cyclone of the 2014 Atlantic hurricane season. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency. The Core Observatory was launched Feb. 27 from Japan and began its prime mission on May 29, just in time for the hurricane season.

Solar energy gets a boost: 'Singlet fission' can increase solar cell efficiency by as much as 30 percent

Science Daily - Tue, 08/07/2014 - 5:21pm
Scientists have reviewed chemists' work on "singlet fission," a process in which a single photon generates a pair of excited states. This conversion process has the potential to boost solar cell efficiency by as much as 30 percent.

Many Texans eligible for subsidies from ACA still believe coverage is too expensive

Science Daily - Tue, 08/07/2014 - 5:21pm
Half of Texans who are eligible for premium subsidies under the Affordable Care Act (ACA) and who looked for health plans in the ACA's Health Insurance Marketplace said cost was the main reason they didn't enroll in a plan. The report specifically looked at lower- to middle-income families in Texas who don't have access to health insurance through an employer and who earn too much to qualify for public programs. That group includes approximately 2 million uninsured Texans and is a key target population of the ACA.

Astronomers bring the third dimension to a doomed star's outburst

Science Daily - Tue, 08/07/2014 - 5:19pm
In the middle of the 19th century, the massive binary system Eta Carinae underwent an eruption that ejected at least 10 times the sun's mass and made it the second-brightest star in the sky. Now, a team of astronomers has used extensive new observations to create the first high-resolution 3-D model of the expanding cloud produced by this outburst.

Harmful hookahs: Many young smokers aren't aware of danger

Science Daily - Tue, 08/07/2014 - 5:18pm
Despite warnings that hookah smoking can be just as dangerous as cigarettes, many young adults believe that using the water pipes is not harmful to their health, according to a study. "With hookah smoking on the rise, particularly among young adults, our goal was to identify factors influencing perceptions, attitudes and preferences toward hookah smoking," said the lead researcher.

Stretching forces shaped Jupiter moon's surface, laboratory model suggests

Science Daily - Tue, 08/07/2014 - 5:18pm
Processes that shaped the ridges and troughs on the surface of Jupiter's icy moon Ganymede are likely similar to tectonic processes seen on Earth, according to a team of researchers. To arrive at this conclusion, the team subjected physical models made of clay to stretching forces that simulate tectonic action.

Advances in mollusk parasite culturing methods drives research

Science Daily - Tue, 08/07/2014 - 5:18pm
Researchers dug into the last 70 years of peer-reviewed publications about protozoan parasites that infest bivalve mollusks and found that when an organism can be cultured in the laboratory, a three to 10 fold increase in papers and greater understanding result. Four protozoan parasitic genera that threaten natural and bivalve populations were studied. Increased understanding about how they function, interact and evolve enhances potential protection of food resources.

New compounds that could affect circadian rhythm uncovered in study

Science Daily - Tue, 08/07/2014 - 5:17pm
A surprising new role has been found for a pair of compounds that have the potential to alter circadian rhythm, the complex physiological process, present in most living things, that responds to a 24-hour cycle of light and dark. At least one of these compounds could be developed as a chemical probe to uncover new therapeutic approaches to a range of disorders, including diabetes and obesity.

Cognitive assessment provides window into proficiency level of robot-assisted surgeons

Science Daily - Tue, 08/07/2014 - 5:17pm
Cognitive assessment can effectively measure the expertise of robotic surgeons with varying levels of experience, researchers have determined. For the cognitive testing, the participants’ cognitive engagement, mental workload and mental state were calculated from the measured EEG during each task. When they compared the results of both testing approaches among the three groups, the researchers found that cognitive assessment detected significant differences that were not identified by the tool-based metrics available through the surgical robot.
