Immersed in violence: How 3-D gaming affects video game players
Playing violent video games in 3-D makes everything seem more real – and that may have troubling consequences for players, a new study reveals. Researchers found that people who played violent video games in 3-D showed more evidence of anger afterward than did people who played using traditional 2-D systems -- even those with large screens.

In disease outbreak management, flexibility can save lives, money
A new, more flexible, approach for responding to and managing disease outbreaks has been developed that could save many lives and millions of dollars. The approach, called 'adaptive management,' allows decision-makers to use knowledge gained during an outbreak to update ongoing interventions with the goal of containing outbreaks more quickly, efficiently, and effectively.

Let there be light: Evolution of complex bioluminescent traits may be predictable
A longstanding question among scientists is whether evolution is predictable. A team of researchers from University of California Santa Barbara may have found a preliminary answer. The genetic underpinnings of complex traits in cephalopods may in fact be predictable because they evolved in the same way in two distinct species of squid.

Novel approach for treating non-cardiac chest pain suggested
Chest pain doesn't necessarily come from the heart. An estimated 200,000 Americans each year experience non-cardiac chest pain. New research suggests a novel approach to treating non-cardiac chest pain due to esophageal hypersensitivity. The treatment involves a drug called dronabinol, a cannabinoid receptor activator that has traditionally been used to treat nausea and vomiting in HIV patients and for cancer patients undergoing chemotherapy.

Could I squeeze by you? Scientists model molecular movement within narrow channels of mesoporous nanoparticles
Scientists have developed deeper understanding of the ideal design for mesoporous nanoparticles used in catalytic reactions, such as hydrocarbon conversion to biofuels. The research will help determine the optimal diameter of channels within the nanoparticles to maximize catalytic output.

Cosmic rays threaten future deep-space astronaut missions
Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky, concludes a new article.

Impressions shaped by facial appearance foster biased decisions
Research in recent years has shown that people associate specific facial traits with an individual's personality. People consistently associate trustworthiness, competence, dominance, and friendliness with specific facial traits. According to a new article, people rely on these subtle facial traits to make important decisions, from voting for a political candidate to convicting a suspect for a crime. The authors present its real-world consequences and discuss potential ways of overcoming it.

Research highlights extent, effects of school violence in U.S.
Six percent of U.S. children and youth missed a day of school over the course of a year because they were the victim of violence or abuse at school. "This study really highlights the way school violence can interfere with learning," says the lead author. "Too many kids are missing school because they do not feel safe."

Resetting the circadian clock: Shift workers might want to skip high-iron foods at night
Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don’t disrupt the circadian clock in their livers. "Iron is like the dial that sets the timing of the clock," the lead researcher says. "Discovering a factor, such as iron, that sets the circadian rhythm of the liver may have broad implications for people who do shift work."
