San Diego, Calif. (April 18, 2014) ― A new study in the American Journal of Preventive Medicine analyzing weekly patterns in health-related Google searches reveals a recurring pattern that could be leveraged to improve public health strategies.

Investigators from San Diego State University, the Santa Fe Institute, Johns Hopkins University, and the Monday Campaigns, analyzed "healthy" Google searches (searches that included the term healthy and were indeed health-related, e.g., "healthy diet") originating in the U.S. from 2005 to 2012. They found that on average, searches for health topics were 30 percent more frequent at the beginning of the week than on days later in the week, with the lowest average number of searches on Saturday.

PROVIDENCE, R.I. [Brown University] — Asteroid and comet impacts can cause widespread ecological havoc, killing off plants and animals on regional or even global scales. But new research from Brown University shows that impacts can also preserve the signatures of ancient life at the time of an impact.

A research team led by Brown geologist Pete Schultz has found fragments of leaves and preserved organic compounds lodged inside glass created by a several ancient impacts in Argentina. The material could provide a snapshot of environmental conditions at the time of those impacts. The find also suggests that impact glasses could be a good place to look for signs of ancient life on Mars.

The work is published in the latest issue of Geology Magazine.

Myelin, the electrical insulating material long believed to be essential for the fast transmission of impulses along the axons of nerve cells, is not as ubiquitous as thought, according to a new paper that turns 160 years of neuroscience on its head.

During the 20 year span of global warming policy debates, climate scientists have used an estimate of soil organic carbon sequestration rates suggesting that soil organic carbon can be sequestered by simply switching from moldboard or conventional tillage systems to no-till systems.

Optics researchers from the University of Central Florida's College of Optics&Photonics and the University of Arizona are working on a new technique to aim a high-energy laser beam into clouds to make it rain or trigger lightning. They are developing the a technique to surround a primary beam with a second beam that acts as an energy reservoir, sustaining the central beam to greater distances than previously possible.

The secondary "dress" beam refuels and helps prevent the dissipation of the high-intensity primary beam, which on its own would break down quickly.

A new article reports that listening to religious music is associated with a decrease in anxiety about death and increases in life satisfaction, self-esteem, and sense of control over their lives among older Christians. 

The associations are similar for blacks and whites, women and men, and individuals of both low- and high-socioeconomic status.
