Under the Coalition Government which came to power in Britain in May 2010, major changes in the community supervision of offenders are underway in England and Wales. Under the new contract for electronic monitoring (EM) (the third since 1999), the government is planning a huge increase in the use of GPS tracking by 2015. Using GPS tracking could well come to be seen as a more reliable and credible way of 'doing' offender management. The government is planning to create the largest and most advanced electronic monitoring (EM) scheme in the world, using combined GPS tracking ...

(NEW YORK, NY, August 18, 2014) – Patients who rely on pacemakers and defibrillators to maintain a normal heart rhythm run the risk of serious health complications if they don't fully understand how the devices work and what to do when they experience an irregular heartbeat. But a study from Columbia University School of Nursing published this month in the Journal of Cardiovascular Nursing found that 40 percent of patients with these devices had little to no ability to understand information about their cardiac health. "As a nurse practitioner, I use every patient encounter ...

Social integration, including strong family ties, can protect one's well-being and even reduce the impact high-risk genes have on health. Scientists call this phenomenon a gene-environment interaction. An Indiana University study focusing on substance abuse, however, found that a three-way interplay of gender, genetics and social integration produced the different outcomes for men and women. The study looked at men and women with a genetic sensitivity to stressful situations. Strong family and community ties were protective for such men, reducing their risk of abusing ...

(Boston)—Probing deeper into the complex decisions that parents and providers face regarding the human papilloma virus (HPV) vaccine, researchers found that though both parties appreciated importance of the HPV vaccine, their personal assumptions surrounding timing of administration relative to onset of sexual activity resulted in decreased vaccination rates. Researchers at Boston University School of Medicine (BUSM) conducted hundreds of interviews to offer new insights into this frequent—and often controversial—clinic room conversation. Their findings and recommendations ...

Feeling that conventional doctors did not take their suffering seriously, women instead sought out hormonal treatments for menopausal symptoms from anti-aging clinicians, according to a Case Western Reserve University study that investigated the appeal of anti-aging medicine. Some women also feared the harmful side effects from conventional hormone replacement therapy (HRT) that had shown increased risks for cancer, heart disease and high blood pressure. Yet, they thought that the bioidentical, "natural" hormones their anti-aging doctors prescribed were safe, despite ...

SAN FRANCISCO — While some suggest that flexible work arrangements have the potential to reduce workplace inequality, a new study finds these arrangements may exacerbate discrimination based on parental status and gender. Study author Christin Munsch, an assistant professor of sociology at Furman University, analyzed the reactions both men and women received when making flexible work requests — meaning that they either asked to work from home or to work non-traditional hours. Among those who made flexible work requests, men who asked to work from home two days a week ...

SAN FRANCISCO — While previous research has documented the existence of a racial hierarchy within the dating world with white women and men on top, a new study finds that in certain circumstances multiracial daters are actually seen as more desirable than individuals from all other racial groups, including whites. "The most interesting and surprising finding from our study is that some white-minority multiracial daters are, in fact, preferred over white and non-white daters," said Celeste Vaughan Curington, a doctoral student in sociology at the University of Massachusetts-Amherst ...

SAN FRANCISCO — Mental health experts in the past three decades have emphasized the dangers of post-partum depression for mothers, but a University of Kansas researcher says expanding awareness of several other perinatal mental health conditions is important for all new parents, including fathers. This awareness has become even more critical as "super mom" and "super dad" pressures continue to grow, said Carrie Wendel-Hummell, a KU doctoral candidate in sociology, who will present her study on perinatal mental health disorders at the 109th Annual Meeting of the American ...

SAN FRANCISCO — The "Great Recession" may have put a dent in many older adults' pocketbooks, but a new study, which will be presented at the 109th Annual Meeting of the American Sociological Association, finds that more than 40 percent reported a decrease in "financial strain" between 2006 and 2010. Researcher Lindsay R. Wilkinson, an assistant professor of sociology in Baylor University's College of Arts & Sciences, drew on 5,205 respondents from the Health and Retirement Study (HRS) to examine the effect of financial strain on the mental health and use of mood-altering ...

High-intensity exercise can help stable heart transplant patients reach higher levels of exercise capacity, and gain better control of their blood pressure than moderate intensity exercise, investigators report in a new study published in the American Journal of Transplantation. Recent research shows that high-intensity interval exercise—training for a few minutes at close to the maximum heart rate—is safe and more efficient than moderate exercise for improving exercise capacity in different groups of patients with heart disease. Researchers led by Christian Dall, PhD ...

Boston, MA – A new study led by researchers at Brigham and Women's Hospital (BWH) and Rush University Medical Center, reveals how early changes in brain DNA methylation are involved in Alzheimer's disease. DNA methylation is a biochemical alteration of the building blocks of DNA and is one of the markers that indicate whether the DNA is open and biologically active in a given region of the human genome. The study is published online August 17, 2014 in Nature Neuroscience. According to the researchers, this is the first large-scale study employing epigenome-wide association ...

Local surface uplift can block rivers, particularly in mountainous regions. The impounded water, however, always finds its way downstream, often cutting a narrow gorge into the rocks. Subsequent erosion of the rocks can lead to a complete eradication of this initial incision, until not a trace is left of the original breakthrough. In extreme cases the whole gorge disappears, leaving behind a broad valley with a flat floodplain. Previously, the assumption was that this transition from a narrow gorge to a wide valley was driven by gorge widening and the erosion of the walls ...

A team led by researchers at the University of Exeter Medical School and King's College London has uncovered some of the strongest evidence yet that epigenetic changes in the brain play a role in Alzheimer's disease. Epigenetic changes affect the expression or activity of genes without changing the underlying DNA sequence and are believed to be one mechanism by which the environment can interact with the genome. Importantly, epigenetic changes are potentially reversible and may therefore provide targets for the development of new therapies. Globally, more than 26 million ...

(SALT LAKE CITY) – In an environment where others struggle to survive, Tibetans thrive in the thin air on the Tibetan Plateau, with an average elevation of 14,800 feet. A study led by University of Utah scientists is the first to find a genetic cause for the adaptation – a single DNA base pair change that dates back 8,000 years – and demonstrate how it contributes to the Tibetans' ability to live in low oxygen conditions. The study appears online in the journal Nature Genetics on Aug. 17, 2014. "These findings help us understand the unique aspects of Tibetan adaptation ...

The electronics we use for our computers only knows two different states: zero or one. Quantum systems on the other hand can be in different states at once, they can store a superposition of "zero" and "one". This phenomenon could be used to build ultrafast quantum computers, but there are several technological obstacles that have to be overcome first. The biggest problem is that quantum states are quickly destroyed due to interactions with the environment. At TU Wien (Vienna), scientists have now succeeded in using a protection effect to enhance the stability of a particularly ...

NEW YORK, NY (August 17, 2014) —Researchers at Columbia University Medical Center (CUMC) have identified the immune cells responsible for destroying hair follicles in people with alopecia areata, a common autoimmune disease that causes hair loss, and have tested an FDA-approved drug that eliminated these immune cells and restored hair growth in a small number of patients. The results appear in today's online issue of Nature Medicine. In the paper, the researchers report initial results from an ongoing clinical trial of the drug, which has produced complete hair regrowth ...

The universe has so many black holes that it's impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big, and colossal. Astronomers know that black holes ranging from about 10 times to 100 times the mass of our sun are the remnants of dying stars, and that supermassive black holes, more than a million times the mass of the sun, inhabit the centers of most galaxies. But scattered across the universe like oases in a desert are a few apparent black holes of a more ...

Cold Spring Harbor, NY – With three billion letters in the human genome, it seems hard to believe that adding a DNA base here or removing a DNA base there could have much of an effect on our health. In fact, such insertions and deletions can dramatically alter biological function, leading to diseases from autism to cancer. Still, it is has been difficult to detect these mutations. Now, a team of scientists at Cold Spring Harbor Laboratory (CSHL) has devised a new way to analyze genome sequences that pinpoints so-called insertion and deletion mutations (known as "indels") ...

One of the most bizarre-looking fossils ever found - a worm-like creature with legs, spikes and a head difficult to distinguish from its tail – has found its place in the evolutionary Tree of Life, definitively linking it with a group of modern animals for the first time. The animal, known as Hallucigenia due to its otherworldly appearance, had been considered an 'evolutionary misfit' as it was not clear how it related to modern animal groups. Researchers from the University of Cambridge have discovered an important link with modern velvet worms, also known as onychophorans, ...

VIDEO: Human neurons firing Click here for more information. A genetic variation linked to schizophrenia, bipolar disorder and severe depression wreaks havoc on connections among neurons in the developing brain, a team of researchers reports. The study, led by Guo-li Ming, M.D., Ph.D., and Hongjun Song, Ph.D., of the Johns Hopkins University School of Medicine and described online Aug. 17 in the journal Nature, used stem cells generated from people with and without mental illness ...

As children learn basic arithmetic, they gradually switch from solving problems by counting on their fingers to pulling facts from memory. The shift comes more easily for some kids than for others, but no one knows why. Now, new brain-imaging research gives the first evidence drawn from a longitudinal study to explain how the brain reorganizes itself as children learn math facts. A precisely orchestrated group of brain changes, many involving the memory center known as the hippocampus, are essential to the transformation, according to a study from the Stanford University ...

Researchers have long suspected that major mental disorders are genetically-rooted diseases of synapses – the connections between neurons. Now, investigators supported in part by the National Institutes of Health have demonstrated in patients' cells how a rare mutation in a suspect gene disrupts the turning on and off of dozens of other genes underlying these connections. "Our results illustrate how genetic risk, abnormal brain development and synapse dysfunction can corrupt brain circuitry at the cellular level in complex psychiatric disorders," explained Hongjun Song, ...

People with schizophrenia struggle to turn goals into actions because brain structures governing desire and emotion are less active and fail to pass goal-directed messages to cortical regions affecting human decision-making, new research reveals. Published in Biological Psychiatry, the finding by a University of Sydney research team is the first to illustrate the inability to initiate goal-directed behaviour common in people with schizophrenia. The finding may explain why people with schizophrenia have difficulty achieving real-world goals such as making friends, completing ...

Bragging of sexual conquests, suggestive jokes and innuendo, and sexual one-upmanship can all be a part of demonstrating one's manhood, especially for young men eager to exert their masculinity. But how does masculinity manifest itself among young men who have pledged sexual abstinence before marriage? How do they handle sexual temptation, and what sorts of challenges crop up once they're married? "Sexual purity and pledging abstinence are most commonly thought of as feminine, something girls and young women promise before marriage," said Sarah Diefendorf, a sociology ...
