SAN FRANCISCO -- Where you live could affect whether or not you spend compulsively, according to new research from San Francisco State University published today in the Journal of Consumer Culture.

Individuals who live in wealthy neighborhoods are more likely to have materialistic values and poor spending habits, the study says, particularly if they are young, living in urban areas and relatively poor compared with their surroundings. The study is the first to show a connection between neighborhood socioeconomic status and materialism.

PHILADELPHIA— People receiving mental health care are up to four times more likely to be infected with HIV than the general population, according to a new study published Feb. 13 in the American Journal of Public Health from researchers at Penn Medicine and other institutions who tested over 1,000 patients in care in Philadelphia and Baltimore.

DETROIT – Enhancing the brain's inherent ability to rebuild itself after a stroke with molecularcomponents of stem cells holds enormous promise for treating the leading cause of long-termdisability in adults.

Michael Chopp, Ph.D., Scientific Director of the Henry Ford Neuroscience Institute, will presentthis approach to treating neurological diseases Thursday, Feb. 13, at the American HeartAssociation's International Stroke Conference in San Diego.

Researchers have tied a particular gene to the development of cortical convolutions—the prominent but enigmatic folds covering the surface of the human brain. Their discovery should shed some light on these characteristic contours, which have been the subject of wild speculation for ages, and perhaps also provide a better understanding of how such brain ridges form, how they evolved from our pre-human ancestors and, ultimately, how they influence brain function.

Fifty years of research has revealed the sad truth that the children of lower-income, less-educated parents typically enter school with poorer language skills than their more privileged counterparts. By some measures, 5-year-old children of lower socioeconomic status (SES) score two years behind on standardized language development tests by the time they enter school.

Austin - February 13, 2014 - Social media can do more than just entertain us and keep us connected. It also can help scientists better understand human behavior and social dynamics. The volume of data created through new technology and social media such as Facebook and Twitter is lending insight into everything from mapping modern family dynamics to predicting postpartum depression.

In addition to their trouble with reading, people with dyslexia also have greater difficulty than typical readers do when it comes to managing competing sensory cues, according to a study reported February 13 in Current Biology, a Cell Press publication. The findings suggest that action video games might improve literacy skills in those with dyslexia, which represent five to ten percent of the population.

Researchers at the University of California, San Diego School of Medicine have discovered that a well-known protein has a new function: It acts in a biological circuit to determine whether an immature neural cell remains in a stem-like state or proceeds to become a functional neuron.

Many psychiatric disorders are accompanied by memory deficits. Basel scientists have now identified a network of genes that controls fundamental properties of neurons and is important for human brain activity, memory and the development of schizophrenia. Their results have been published in the online edition of the US journal Neuron.

Women's blood clot risk remains elevated for at least 12 weeks after delivering a baby — twice as long as previously recognized, according to a large study presented at the American Stroke Association's International Stroke Conference 2014.

The chance of a blood clot rises during pregnancy, when platelets and other blood-clotting factors increase. The risk peaks around the time of delivery, but researchers found that afterwards it remained:

Giving intravenous magnesium to stroke patients soon after the start of symptoms, in an attempt to protect brain cells deprived of oxygen, failed to improve stroke-related disability 3 months later, according to research presented at the American Stroke Association's International Stroke Conference 2014.

Investigators showed that paramedics can successfully deliver intravenous medications to most stroke patients within an hour after symptoms begin. This is the "golden hour" the time in which patients have the best chance to survive and avoid long-term neurological damage.

In the first study of its kind, a consortium led by UCLA physicians found that giving stroke patients intravenous magnesium within an hour of symptom onset does not improve stroke outcomes, according to research presented today at the American Stroke Association's International Stroke Conference.

Scientists know there is a strong genetic component to bipolar disorder, but they have had an extremely difficult time identifying the genes that cause it. So, in an effort to better understand the illness's genetic causes, researchers at UCLA tried a new approach.

EVANSTON, Ill. --- Today Americans are looking to their marriages to fulfill different goals than in the past — and although the fulfillment of these goals requires especially large investments of time and energy in the marital relationship, on average Americans are actually making smaller investments in their marital relationship than in the past, according to new research from Northwestern University.

A report in the Feb. 13 New England Journal of Medicine confirms previous studies suggesting that long-term treatment with the type of drugs commonly prescribed to treat restless leg syndrome (RLS) can cause a serious worsening of the condition in some patients.
