The diversity of microbes on the skin of frog species in Brazil's Atlantic Forest can vary with habitat, according to a new study.

According to a study encompassing the entire Finnish population, traumatic brain injury associated with an increased risk for dementia in working-age adults. Yet, no such relationship was found between traumatic brain injury and later onset of Parkinson's disease or ALS. The researchers believe that these results may play a significant role for the rehabilitation and long-term monitoring of traumatic brain injury patients.

The microbes inhabiting a hydraulically fractured shale formation produce toxic, corrosive sulfide through a poorly understood pathway, researchers report. The team's findings reveal that the oil and gas industry may need new ways to monitor and mitigate sulfide-producing bacteria in fractured shales.

Two complementary nanotechnologies have been combined to develop a 3-D computer chip that could enable new generation of energy-efficient electronics for data-intensive applications.

Wind-driven incursions of warm water forced the retreat of glaciers in West Antarctica during the past 11,000 years, a new report explains. These new results enable researchers to better understand how environmental change may impact future sea-level rise from this climate-sensitive region.

A new study has shown that the infectious agent responsible for malaria, the Plasmodium parasite, is able to to sense and actively adapt to the host's nutritional status.

Moving genes about could help cells to respond to change according to scientists. Changing the location of a gene within a cell alters its activity. Contrary to expectations, this latest study reveals that each gene doesn't have an ideal location in the cell but are constantly moving. This work, which has also inspired a musical collaboration, suggests that moving genes could help cells to fine-tune the volume of each gene to suit the cell's needs.

While the negative health and environmental effects of mining and burning coal are well documented, simply transporting and storing coal can also adversely affect the health outcomes of individuals living near coal-fired power plants. New research explores the health and environmental costs of coal storage and transportation, finding that increases in the level of coal stockpiles held by US power plants increase local air pollution levels, which in turn increases the average infant and adult mortality rates in the communities near these plants.

Watching television sometimes gets a bad rap -- especially where children and screen time are concerned -- but not all of it's deserved, suggest authors of a new report.

A study by social psychologists shows that people can reliably tell if someone is richer or poorer than average just by looking at a neutral face without any expression. This is due to visibility of the positions of muscles that become etched in the face over time as a result of repeated life experiences.

Green infrastructure is an attractive concept, but there is concern surrounding its effectiveness. Researchers are using a mathematical technique traditionally used in earthquake engineering to determine how well green infrastructure works and to communicate with urban planners, policymakers and developers.

Older Americans are cheating on their spouses more than their younger counterparts, with 20 percent of married Americans over age 55 reporting they've engaged in extramarital sex. Just 14 percent of those under age 55 say they've cheated.

Researchers asked people why they use Facebook, then identified four categories of users.

Westerners view handshaking more positively than do East Asians, researchers report in a new study. Western men also rate handshakes initiated by men and women differently, the study found.

When exposed to potential predators as an embryo, the invasive American bullfrog becomes harder to kill when it becomes a tadpole, according to a new study.
