When parents use material goods in these ways, their children, when grown, are on average more likely to believe that success in life is defined by the quality and number of material goods an individual owns or that acquiring certain products will make them more attractive. According to Richins, previous research has shown that adults who define themselves or others by their possessions are at a much higher risk for marital problems, gambling, financial debt and decreased well-being. Materialism also contributes to environmental degradation due to overconsumption and waste of goods.

New Year's resolution-makers should beware of skewed perceptions. People tend to believe good behaviors are more beneficial in reaching goals than bad behaviors are in obstructing goals, according to a University of Colorado Boulder-led study.

A dieter, for instance, might think refraining from eating ice cream helps his weight-management goal more than eating ice cream hurts it, overestimating movement toward versus away from his target.

A research team at Bielefeld University has succeeded in teaching the only robot of its kind in the world how to walk. Its first steps have been recorded in a video. You can watch them in Bielefeld University's latest posting on 'research_tv'. The robot is called Hector, and its construction is modelled on a stick insect. Inspired by the insect, Hector has passive elastic joints and an ultralight exoskeleton.

DURHAM, N.C. - Duke University scientists have developed new forensic tracers to identify coal ash contamination in water and distinguish it from contamination coming from other sources.

A team of researchers from the University of California, San Diego have demonstrated a way to emit and control quantum light generated using a chip made from silicon--one of the most widely used materials for modern electronics.

The UC San Diego researchers recently described their new device's performance online in the journal Nature Communications, available via Open Access .

No visit to Rome is complete without a visit to the Pantheon, Trajan's Markets, the Colosseum, or the other spectacular examples of ancient Roman concrete monuments that have stood the test of time and the elements for nearly two thousand years. A key discovery to understanding the longevity and endurance of Roman architectural concrete has been made by an international and interdisciplinary collaboration of researchers using beams of X-rays at the Advanced Light Source (ALS) of the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab).

Driving vehicles that use electricity from renewable energy instead of gasoline could reduce the resulting deaths due to air pollution by 70 percent. This finding comes from a new life cycle analysis of conventional and alternative vehicles and their air pollution-related public health impacts, published Monday, Dec. 15, 2014, in the Proceedings of the National Academy of Sciences.

ORANGE, Calif. - Researchers in Chapman University's Food Science Program and their collaborators at University of Washington have just published a study on the presence of Salmonella and E. coli on certain herbs sold at farmers' markets. The study focused on farmers' markets in Los Angeles and Orange counties in California, as well as in the Seattle, Washington, area. Specifically tested were samples of the herbs cilantro, basil and parsley. Of the 133 samples tested from 13 farmers' markets, 24.1 percent tested positive for E.

A new study indicates that women with mobility disabilities often experience problems during pregnancy related to their functional impairments.

The study included 8 women with spinal cord injuries, 4 with cerebral palsy, and 10 with other conditions. Impairment-related complications during pregnancy included falls, urinary tract and bladder problems, wheelchair fit and stability problems, significant shortness of breath, increased spasticity, bowel management difficulties, and skin integrity problems.

BLOOMINGTON, Ind. -- Research by Indiana University scientists finds that soil may be a significant and underappreciated source of nitrous acid, a chemical that plays a pivotal role in atmospheric processes such as the formation of smog and determining the lifetime of greenhouse gases.

Scientists from the Department of Energy's Pacific Northwest National Laboratory will present a variety of research at the 2014 American Geophysical Union Fall Meeting, which runs Monday, Dec. 15 through Friday, Dec. 19 at the Moscone Convention Center in San Francisco. Noteworthy PNNL research presentations include the following topics:

Even with global warming cold air outbreaks will remain

Leading conservation scientists from around the world have called for a substantial role for nuclear power in future energy-generating scenarios in order to mitigate climate change and protect biodiversity.

In an open letter to environmentalists with more than 60 signatories, the scientists ask the environmental community to "weigh up the pros and cons of different energy sources using objective evidence and pragmatic trade-offs, rather than simply relying on idealistic perceptions of what is 'green' ".

Researchers at Yale and Boston University and their Russian collaborators have found that occasional heroin use by HIV-positive patients may be particularly harmful to the immune system and worsens HIV disease, compared to persistent or no heroin use.

The findings are published in the journal AIDS and Behavior.

WASHINGTON, Dec. 15, 2014--Credit card fraud and identify theft are serious problems for consumers and industries. Though corporations and individuals work to improve safeguards, it has become increasingly difficult to protect financial data and personal information from criminal activity. Fortunately, new insights into quantum physics may soon offer a solution.

A study conducted by University of Granada scientists (from the Physiology, Obstetrics and Gynaecology Departments) and from the San Cecilio Clinical Hospital (Granada) has demonstrated that delaying the cutting of the umbilical cord in newborns by two minutes leads to a better development of the baby during the first days of life.

This multidisciplinary work, published in the prestigious journal Pediatrics reveals that the time in cutting the umbilical cord (also called umbilical cord clampling) influences the resistance to oxidative stress in newborns.
