WASHINGTON, DC, May 24, 2011 — Children whose parents get divorced generally don't experience detrimental setbacks in the pre-divorce period, but often fall behind their peers—and don't catch up—when it comes to math and interpersonal social skills after their parents begin the divorce process, according to a new study.
MADISON — Divorce is a drag on the academic and emotional development of young children, but only once the breakup is under way, according to a study of elementary school students and their families.
"Children of divorce experience setbacks in math test scores and show problems with interpersonal skills and internalizing behavior during the divorce period," says Hyun Sik Kim, a Ph.D. candidate in sociology at the University of Wisconsin-Madison. "They are more prone to feelings of anxiety, loneliness, low self-esteem and sadness."
Until a decade, it was believed that differences between people were due solely to the existence of genetic changes, which are alterations in the sequence of our genes. The discoveries made during these last ten years show that beings with the same genetics like the twins and cloned animals may have different characteristics and disease due to epigenetic changes.
NEW YORK — June 2, 2011 — A new study by Columbia Business School Professor Paul Ingram, Kravis Professor Business, Management and senior scholar at the Jerome A. Chazen Institute for International Business at Columbia Business School; Hayagreeva Rao, Atholl McBean Professor of Organizational Behavior and Human Resources, Stanford Graduate School of Business; and Qingyuan (Lori) Yue, Assistant Professor of Management and Organization, USC Marshall School of Business, found evidence of how firms engage in regulatory arbitrage and make decisions based on a state's regulatory policies.
Sufferers of the sleep disorder obstructive sleep apnoea could benefit from following a low energy diet to lose weight, finds research published on bmj.com today.
Sleep apnoea is a common disorder caused by abnormal pauses in breathing during sleep. Sufferers rarely feel refreshed after a night's sleep and the disease is linked to negative health effects such as increased risk of accidents, decreased quality of life and a higher chance of premature death.
Excessive use of antimicrobials in livestock promotes resistance and risks the future health of both animals and humans, warn experts in an editorial published by Student BMJ today.
Jørgen Schlundt and colleagues at the National Food Institute in Denmark argue that the routine use of antimicrobials can be reduced substantially, while maintaining profitable animal production, and call for their use to be monitored in all countries.
BIRMINGHAM, Ala. – Although cytomegalovirus infection is a known cause of birth defects, including permanent hearing loss, most CMV infections in infants are not identified early, when interventions can lessen the effects of hearing loss.
Swabbing a newborn's mouth for saliva can be used to quickly and effectively screen for cytomegalovirus (CMV) infection, a leading cause of hearing loss in children, says research in the June 2 issue of the New England Journal of Medicine.
To survive temperatures below -50 ° C and gale-force winds above 180 km/h during the Antarctic winter, Emperor penguins form tightly packed huddles and, as has recently been discovered – the penguins actually coordinate their movements to give all members of the huddle a chance to warm up. Physicist Daniel P. Zitterbart from the University of Erlangen-Nuremberg, Germany, recently spent a winter at Dronning Maud Land in the Antarctic, making high-resolution video recordings of an Emperor penguin colony. Together with biophysicist Ben Fabry from Erlangen University, physiologist James P.
ANN ARBOR, Mich. – Surgery death rates have dropped nationwide over the past decade, according to a University of Michigan Health System study that reveals cancer surgeries have seen the most dramatic improvement in safety.
The U-M study in this week's New England Journal of Medicine shows surgery mortality dropped substantially for eight different high-risk surgeries performed on 3.2 million Medicare patients from 1999 to 2008.
FLAGSTAFF, Ariz. — June 1, 2011 — Deadly bacteria may be evolving antibiotic resistance by mimicking human proteins, according to a new study by the Translational Genomics Research Institute (TGen).
This process of "molecular mimicry" may help explain why bacterial human pathogens, many of which were at one time easily treatable with antibiotics, have re-emerged in recent years as highly infectious public health threats, according to a study published in PLoS One.
CHICAGO -- Newly diagnosed cancer patients frequently face hurdles in obtaining an appointment for care with an oncologist, according to new research from the Perelman School of Medicine at the University of Pennnsylvania that will be presented Saturday, June 4 at the 2011 annual meeting of American Society of Clinical Oncology (Abstract #6128).
Intensity modulated radiation therapy, a newer, more precise form of radiation therapy, causes fewer gastrointestinal side effects when combined with hormone therapy than using three-dimensional radiation therapy, according to a study published in the June issue of the International Journal of Radiation Oncology•Biology•Physics, the official scientific journal of the American Society for Radiation Oncology (ASTRO).
(CHICAGO) –– Women with the BRCA1 or BRCA2 gene mutations, which are linked to a very high risk of breast and ovarian cancer, can safely take hormone-replacement therapy (HRT) to mitigate menopausal symptoms after surgical removal of their ovaries, according to new research from the Perelman School of Medicine at the University of Pennsylvania which will be presented Monday, June 6 during the American Society for Clinical Oncology's annual meeting (Abstract #1501).
