Young genes that appeared after the primate branch split off from other mammal species are more likely to be expressed in the developing human brain, a new analysis finds. The correlation suggests that evolutionarily recent genes, which have been largely ignored by scientists thus far, may be responsible for constructing the uniquely powerful human brain. The findings are published October 18 in the online, open access journal PLoS Biology. "We found that there is a correlation between new gene origination and the evolution of the brain," said senior author Manyuan Long, ...

Researchers from Sweden have uncovered an association between shift work and increased risk of multiple sclerosis (MS). Those who engage in off-hour employment before the age of 20 may be at risk for MS due to a disruption in their circadian rhythm and sleep pattern. Findings of this novel study appear today in Annals of Neurology, a journal published by Wiley-Blackwell on behalf of the American Neurological Association and Child Neurology Society. Previous research has determined that shift work—working during the night or rotating working hours—increases the risk of ...

New research into evolutionary psychology suggests that physical stature affects our preferences in political leadership. The paper, published in Social Science Quarterly, reveals that a preference for physically formidable leaders, or caveman politics, may have evolved to ensure survival in ancient human history. The paper, published by Gregg R. Murray and J. David Schmitz, from Texas Tech University, focuses on evolutionary psychology, the study of universal human behavior which is related to psychological mechanisms which evolved to solve problems faced by humans in ...

Virginia Tech released today results from the first study ever to instrument child football helmets. Youth football helmets are currently designed to the same standards as adult helmets, even though little is known about how child football players impact their heads. This is the first study to investigate the head impact characteristics in youth football, and will greatly enhance the development of improved helmets specifically designed for children. The Auburn Eagles, a local, Montgomery County, Va., youth team consisting of 6 to 8 year old boys, has participated in ...

Customers are a business' best asset. They provide opportunities for new sales and act as an endorsement to products and services when everything's going well. But businesses could be losing sales, customers and their reputation if they're not maintaining a positive relationship by using an effective business CRM system. "As National Customer Service Week demonstrates, customers are the key to good business and growth. CRM systems such as webCRM ensure a business maintains a proactive relationship with its customers," said Stephen Todd of Leicestershire-based ...

Higher surgical costs for adult congenital heart patients is associated with higher rates of inpatient death compared to surgical admissions that incur lower costs, according to a study in Circulation: Quality and Outcomes, a journal of the American Heart Association. In the study, researchers sought to understand resource use by adults undergoing congenital heart surgery in pediatric hospitals, analyze the association between high resource use and inpatient death, and identify risk factors for high resource use. They found that although the number of adults undergoing ...

Young genes that appeared since the primate branch split from other mammal species are expressed in unique structures of the developing human brain, a new analysis finds. The correlation suggests that scientists studying the evolution of the human brain should look to genes considered recent by evolutionary standards and early stages of brain development. "There is a correlation between the new gene origination and the evolution of the brain," said Manyuan Long, PhD, Professor of Ecology & Evolution at the University of Chicago and senior author of the study in PLoS ...

CHICAGO - Between 1998 and 2008, heart-failure related hospitalizations declined substantially among Medicare patients, but at a lower rate for black men, according to a study in the October 19 issue of JAMA. Also, 1-year mortality rates declined slightly during this period, but remain high. "Heart failure (HF) imposes one of the highest disease burdens of any medical condition in the United States with an estimated 5.8 million patients experiencing HF in 2006. The risk of developing HF increases with advancing age, and as a result, HF ranks as the most frequent cause ...

CHICAGO – A review and analysis of 26 validated hospital readmission risk prediction models finds that most, whether for hospital comparison or clinical purposes, have poor predictive ability, according to an article in the October 19 issue of JAMA. "An increasing body of literature attempts to describe and validate hospital readmission risk prediction tools," according to background information in the article. "Predicting hospital readmission risk is of great interest to identify which patients would benefit most from care transition interventions, as well as to risk-adjust ...

CHICAGO – Patients who had undergone hemodialysis using dialyzers that had been sterilized with the use of electron beams were more likely to develop thrombocytopenia (an abnormally low platelet count in the blood, associated with increased risk of bleeding), according to a study in the October 19 issue of JAMA. "Adverse device reactions to hemodialysis treatments are uncommon but can still occur in today's era of hemodialysis membranes and technology. During hemodialysis treatment, patients are exposed to a variety of components of the dialysis circuit and could have ...

New York, NY, October 18, 2011—The U.S. health care system scored 64 out of 100 on key measures of performance, according to the third national scorecard report from the Commonwealth Fund Commission on a High Performance Health System, released today. The scorecard finds that—despite pockets of improvement—the U.S as a whole failed to improve when compared to best performers in this country, and among other nations. The report also finds significant erosion in access to care and affordability of care, as health care costs rose far faster than family incomes. At the same ...

Ecologists are a step closer to understanding one of nature's most extraordinary sights – the 'arribada' or synchronised mass nesting of female olive ridley sea turtles. The new study, published today in the British Ecological Society's Journal of Animal Ecology, is the first to combine three different approaches – genetics, demography and behaviour, and the results should help conserve these vulnerable marine creatures. The study, lead by Virginie Plot of the National Center for Scientific Research (CNRS) in France, gathered three sets of data. First, to get an accurate ...

Antineoplastic agents such as immunotherapies and targeted therapies that specifically target signaling pathways in cancer cells are associated with thyroid dysfunction in 20%-50% of cancer patients taking them, which can adversely affect patients' quality of life, according to a study published Oct. 18 in the Journal of the National Cancer Institute. Over the past two decades, novel antineoplastic agents have been introduced that inhibit specific cellular processes to limit cancer cell growth. Some of these agents cause thyroid dysfunction, which physicians often overlook ...

New research successfully reverses epilepsy-associated pathology by using a sophisticated single-cell modeling paradigm to examine abnormal cell behavior and identify the optimal modulation of channel activity. The study, published by Cell Press in the October 18th issue of Biophysical Journal, describes a procedure that may be useful for rescuing function in organs with excitable cells, such as the heart and pancreas. Ion channels regulate the flow of ions into and out of the cell and are absolutely critical for a wide range of biological processes, including transmission ...

Ottawa, Ontario – October 18, 2011 – Oncolytic virology uses live viruses to sense the genetic difference between a tumor and normal cell. Once the virus finds a tumor cell, it replicates inside that cell, kills it and then spreads to adjacent tumor cells to seed a therapeutic "chain reaction". As reported in today's issue of Cancer Cell, Dr. David Stojdl, a scientist from the Children's Hospital of Eastern Ontario Research Institute at the University of Ottawa has found a way to trick resistant cancer cells into committing suicide following oncolytic virus therapy. When ...

The term "sex offender" conjures different images or meanings for different people. For those accused of sex crimes, it might bring to mind thoughts of lifetime registration on local sex-offender registries and social stigma. For others, the term might mean older adults who have had inappropriate contact with minors or of people who have committed forcible sex crimes against other adults. The term sex offender, however, rarely brings to mind teenagers who have engaged in consensual sexual relations. Until recently, teenagers or young adults convicted of sex ...

NAIROBI, KENYA (14 October 2011)— On a continent battered by weather extremes, famine and record food prices, new research released today from the World Agroforestry Centre documents an exciting new trend in which hundreds of thousands of poor farmers in Southern Africa are now significantly boosting yields and incomes simply by using fast growing trees and shrubs to naturally fertilize their fields. The analysis of two decades of work to bring the soil-enriching benefits of so-called "fertilizer trees" to the nutrient-depleted farms of Africa was published in the most ...

Volcanologists from the Universities of Leicester and Durham have forensically reconstructed the impact of a meteorite on Earth and how debris was hurled from the crater to devastate the surrounding region. New research by Mike Branney, of the University of Leicester's Department of Geology, and Richard Brown, University of Durham, shows that some aspects of giant meteorite impacts onto Earth may mimic the behaviour of large volcanic eruptions. Meteorite impacts are more common than is popularly appreciated – but what happens when the meteorite hits? Direct observation ...
