Impatient people have lower credit scores, study finds Posted: 02 Dec 2011 12:58 PM PST Is there a psychological reason why people default on their mortgages? A new study finds that people with bad credit scores are more impatient -- more likely to choose immediate rewards rather than wait for a larger reward later.

Astronomers find 18 new planets: Discovery is the largest collection of confirmed planets around stars more massive than the sun Posted: 02 Dec 2011 12:58 PM PST Discoveries of new planets just keep coming and coming. A team of astronomers has found 18 Jupiter-like planets in orbit around massive stars. The discoveries further constrain theories of planet formation.

Even unconsciously, sound helps us see Posted: 02 Dec 2011 12:57 PM PST Imagine you are playing ping-pong with a friend. Your friend makes a serve. Information about where and when the ball hit the table is provided by both vision and hearing. And this is how the senses interact in how we perceive the world.

Are doing harm and allowing harm equivalent? Ask fMRI Posted: 02 Dec 2011 12:55 PM PST Individuals and courts deal more harshly with people who actively commit harm than with people who willfully allow the same harm to occur. A new study finds that this moral distinction is psychologically automatic. It requires more thought to see each harmful behavior as morally equivalent.

Many older Floridians have no backup plan after hanging up their keys Posted: 02 Dec 2011 12:55 PM PST Florida is home to one of the highest percentages of residents ages 65 and older in the United States, but very few of them have thought ahead to a time when they will no longer be able to drive a vehicle safely or considered how they will get around without a car, according to a new survey.

Instant nanodots grow on silicon to form sensing array Posted: 02 Dec 2011 12:55 PM PST Scientists have shown that it is now possible to simultaneously create highly reproductive three-dimensional silicon oxide nanodots on micrometric scale silicon films in only a few seconds. Scientists were able to create a square array of such nanodots, using regularly spaced nanoindents on the deposition layer, that could ultimately find applications as biosensors for genomics or bio-diagnostics.

Research improves diagnosis and potential treatment of neuromyelitis optica Posted: 02 Dec 2011 06:19 AM PST Researchers have identified critical steps leading to myelin destruction in neuromyelitis optica (NMO), a debilitating neurological disease that is commonly misdiagnosed as multiple sclerosis. The findings could lead to better care for the thousands of patients around the world with NMO.

Vegetables, fruits, grains reduce stroke risk in women Posted: 01 Dec 2011 01:35 PM PST Swedish women who ate an antioxidant-rich diet had fewer strokes especially if they had no history of cardiovascular disease, according to a new study. The findings persisted even after statistics were adjusted for other risk factors such as smoking and physical activity. Women with the highest level of antioxidants in their diet consumed about half their antioxidants from fruits and vegetables.
