Tel Aviv ― Naukrtis, a Greek trade emporium on Egyptian soil, has long captured the imagination of archaeologists and historians. Not only is the presence of a Greek trading settlement in Egypt during the 7th and 6th century B.C.E. surprising, but the Greeks that lived there in harmony hailed from several Greek states which traditionally warred amongst themselves.
New research led by economists at the University of Warwick reveals that medieval England was not only far more prosperous than previously believed, it also actually boasted an average income that would be more than double the average per capita income of the world's poorest nations today.
Lesbian, gay and bisexual (LGB) adolescents are about 40 percent more likely than other teens to be punished by school authorities, police and the courts, according to a study by Yale University researchers.

INDIANAPOLIS – The most frequent contributors to medication errors and adverse drug events in busy primary care practice offices are communication problems and lack of knowledge, according to a study of a prototype web-based medication error and adverse drug event reporting system.

A new report recently released by the National Science Foundation, titled "Doctorate Recipients from U.S. Universities: 2009," presents a statistical overview of the U.S. doctoral education system in snapshots and long-term trends.
It notes the American system of doctoral education is widely considered the world's best, as evidenced by the large number of international students who choose to pursue a doctorate at U.S. universities. But this status is subject to the many factors that shape U.S. doctoral education.
The Earth has run out of room to expand fisheries, according to a new study led by University of British Columbia researchers that charts the systematic expansion of industrialized fisheries.
November 30, 2010 -- Despite the existence of effective programs for treating alcohol dependencies and disorders, less than a quarter of people who are diagnosed actually seek treatment. In a recent study by Columbia University's Mailman School of Public Health researchers report that people diagnosed with alcoholism at some point in their lifetime were more than 60% less likely to seek treatment if they believed they would be stigmatized once their status is known.
With almost one billion people lacking access to clean, safe drinking water, scientists are reporting development and successful initial tests of an inexpensive new filtering technology that kills up to 98 percent of disease-causing bacteria in water in seconds without clogging. A report on the technology appears in Nano Letters, a monthly American Chemical Society journal.
Experiences with violence cause teens growing up in dangerous neighborhoods to adopt a range of coping strategies, with notable impact whether the violence takes place at home, among friends or during police incidents, a University of Chicago study shows.
The responses to violence include seeking out non-violent friends, avoiding trouble, becoming resigned to the situation, striving to do well in school, or for some, retaliating physically, the authors said.

In addition, fear of death is most common among women than men, which affects their children's perception of death. In fact, 76% of children that report fear of death is due to their mothers avoiding the topic. Additionally, more of these children fear early death and adopt unsuitable approaches when it comes to deal with death.
PROVIDENCE, R.I. [Brown University] — Quitting smoking is certainly healthy for the body, but doctors and scientists haven't been sure whether quitting makes people happier, especially since conventional wisdom says many smokers use cigarettes to ease anxiety and depression. In a new study, researchers tracked the symptoms of depression in people who were trying to quit and found that they were never happier than when they were being successful, for however long that was.
A prescribed set of hospital-wide patient-safety programs can lead to rapid improvements in the "culture of safety" even in a large, complex, academic medical center, according to a new study by safety experts at Johns Hopkins.
Expectant parents who completed a brief relationship-strengthening class around the time their child was born showed lasting effects on each family member's well being and on the family's overall relationships, according to a recent Penn State study.
The team, led by Mark Feinberg, senior research associate in Penn State's Prevention Research Center for the Promotion of Human Development, analyzed the effects of the Family Foundations program for three years after a child was born.
People who are deemed social misfits or "losers" aren't effective leaders, even if they are crusading for a cause that would benefit a larger group, according to new research from Rice University, the University of Texas and Universitat de Valencia.
The study's authors observed the contributions of 80 participants in a repeated public-goods game and found that players were more likely to mimic the actions of a leader they perceived as a high-status individual; they ignored leaders perceived as low-status and, when they had a chance, punished them for trying to lead.
