Is there a brain area for mind-wandering? For religious experience? For reorienting attention? A recent study casts serious doubt on the evidence for these ideas, and rewrites the rules for neuroimaging. Brain mapping experiments attempt to identify the cognitive functions associated with discrete cortical regions. They generally rely on a method known as "cognitive subtraction." However, recent research reveals a basic assumption underlying this approach—that brain activation is due to the additional processes triggered by the experimental task—is wrong "It is such ...

WASHINGTON -- While numerous studies are under way to determine the impacts of the Deepwater Horizon oil spill on the Gulf of Mexico, the extent and severity of these impacts and the value of the resulting losses cannot fully be measured without considering the goods and services provided by the Gulf, says a new report from the National Research Council. The congressionally mandated report offers an approach that could establish a more comprehensive understanding of the impacts and help inform options for restoration activities. Currently, state and federal resource ...

WASHINGTON — Emergency physicians and other emergency department staff were fairly accurate in assessing which patients were drug-seekers in the emergency department, changing their prescribing plans for less than 10 percent of patients after consulting an objective computerized state prescription drug monitoring program (PDMP). The analysis of emergency providers' prescribing patterns and clinical factors associated with suspecting drug-seeking in the ER were published online yesterday in Annals of Emergency Medicine ("Clinician Impression vs. Prescription Drug Monitoring ...

CHAPEL HILL, N.C. — Different factors influence delay between diagnosis and first course of treatment for breast cancer for African-American and White women. The study used data from the Carolina Breast Cancer Study (CBCS) Phase III, a program of UNC Lineberger Comprehensive Cancer Center. Scientists found that among White women, household size and losing a job due to one's diagnosis were reasons for delay in treatment, while among African-American women, the type of treatment received influenced delay. Both African-American and White women experienced delay if they underwent ...

MANHATTAN -- Wind power development does not ruffle the feathers of greater prairie chicken populations, according to the results of a seven-year study from a Kansas State University ecologist and his team. The researchers -- led by Brett Sandercock, professor of biology -- discovered that wind turbines have little effect on greater prairie chickens, and that these grassland birds are more affected by rangeland management practices and by the availability of native prairie and vegetation cover at nest sites. Unexpectedly, the scientists also found that female survival ...

Alexandria, VA -- Scientists have recently confirmed the existence of an impact crater buried below the town of Decorah, Iowa. Scientists first discovered what they thought resembled a crater in 2008, but now it has been corroborated by an airborne geophysical survey and hydrology surveys. Scientists estimate the diameter of the crater at 5.5 kilometers wide, nearly five times the size of the Barringer Meteor Crater in Arizona. Based on the crater's size, scientists calculate that the region was likely hit by a meteorite roughly 250 meters in diameter about 500 million ...

(Boston) - Researchers from Boston University School of Medicine (BUSM) and George Washington University (GWU) have developed a method to rapidly identify pathogenic species and strains causing illnesses, such as pneumonia, that could help lead to earlier detection of disease outbreaks and pinpoint effective treatments more quickly. The findings are featured online in the journal Genome Research. Emerging sequencing technologies have revolutionized the collection of genomic data for bioforensics, biosurveillance and for use in clinical settings. However, new approaches ...

LA JOLLA, CA – July 10, 2013 – Scientists at The Scripps Research Institute (TSRI) have published one of the first laboratory studies of MDPV, an emerging recreational drug that has been sold as "bath salts." The TSRI researchers confirmed the drug's powerful stimulant effects in rats and found evidence that it could be more addictive than methamphetamine, one of the most addictive substances to date. "We observed that rats will press a lever more often to get a single infusion of MPDV than they will for meth, across a fairly wide dose range," said TSRI Associate Professor ...

DALLAS – July 10, 2013 – Researchers at UT Southwestern Medical Center report the identification of a new cellular source for an important disease-fighting protein used in the body's earliest response to infection. The protein interferon-gamma (IFN-γ) keeps viruses from replicating and stimulates the immune system to produce other disease-fighting agents. Neutrophils, the newly identified cellular source of the protein, are the major component of the pus that forms around injured tissue. The researchers also report that the neutrophils appear to produce IFN-γ ...

Boston – July 10, 2013 – Researchers at Joslin Diabetes Center have discovered that when excessive PKC beta is found in the endothelium, the thin layer of cells that line blood vessels, atherosclerosis is exacerbated. Their findings were published on-line on June 11 by Circulation Research. For people with diabetes, the increased risk of cardiovascular disease is an unfortunate reality. This includes atherosclerosis, a condition where the walls of the artery thicken due to accumulating fatty deposits, which can lead to heart attack and stroke. "Heart disease is a major ...

Fires around James Bay continue raging in Canada due to the driest summer the region has seen in 40 years as seen in this Aqua satellite photo from July 09, 2013. These fires have been raging for several weeks now and are also causing other problems besides burning land and causing pollution. About 10 per cent of Quebecers lost electricity on July 5, on the second day of blackouts triggered by the powerful forest fires. Hydro-Quebec said 500,000 households or businesses were affected at the peak of the blackout. Apparently the smoke from forest fires had prompted a ...

PROVIDENCE, R.I. [Brown University] — Researchers from Brown University have shown how tiny graphene microsheets — ultra-thin materials with a number of commercial applications — could be big trouble for human cells. The research shows that sharp corners and jagged protrusions along the edges of graphene sheets can easily pierce cell membranes. After the membrane is pierced, an entire graphene sheet can be pulled inside the cell where it may disrupt normal function. The new insight may be helpful in finding ways to minimize the potential toxicity of graphene, said Agnes ...

In the 2012 presidential election, seven out of 10 Latino immigrants voted for President Obama. As news pundits dissected the defeat of Mitt Romney, they dismissed the Latino vote as unattainable for the Republican Party. But University of Nebraska-Lincoln political scientist Sergio Wals says that's not necessarily the case. In a new study published in the journal Electoral Studies, Wals found that Mexican immigrants who are more politically invested are center or center-right in their political ideologies. That means that at least this segment of the Latino electorate ...

A study made with 191 patients reveal that symptoms of hyperactivity due to the deficit of attention and hyperactivity disorder (ADHD) are associated with more impulsivity and more severity, and probably a worse prognosis in patients with eating disorders. ADHD in adults is poorly investigated and, although several studies have reported associations between this disorder and abnormal eating behaviour, so far it had not been described associations between ADHD and eating disorders in adults. The results of the study conducted by researchers from the group of Psychiatry ...

CORVALLIS, Ore. – Migrant workers are more likely to receive medical care from community health centers in partnership with faith-based organizations, a new study shows, because fear of deportation is lower than they might face at other medical facilities. The study was recently published online in the Journal of Immigrant and Minority Health. Daniel López-Cevallos, associate director of research at Oregon State's Center for Latino/a Studies and Engagement, said this research points to the importance of health services being administered to migrant farmworkers by trusted ...

Children who were later diagnosed with autism spectrum disorder had excessive cerebral spinal fluid and enlarged brains in infancy, a study by a multidisciplinary team of researchers with the UC Davis MIND Institute has found, raising the possibility that those brain anomalies may serve as potential biomarkers for the early identification of the neurodevelopmental disorder. The study is the first to follow the brain-growth trajectories from infancy in children who later develop autism and the first to associate excessive cerebrospinal fluid during infancy with autism. ...

Statins -- the popular class of cholesterol-lowering drugs used widely to prevent recurrent heart disease or stroke as well as risk for having a first cardiac or stroke event -- appear to cause few side effects, according to new research reported in Circulation: Cardiovascular Quality and Outcomes. Researchers conducted the largest meta-analysis on statin side effects to date, reviewing data from 135 previous drug studies to evaluate the safety of the seven statins on the market. They concluded "as a class, adverse events associated with statin therapy are not common." ...

The link between previous termination of pregnancy (abortion) and preterm delivery in a subsequent pregnancy has disappeared over the last 20-30 years, according to a study of data from Scotland published in this week's PLOS Medicine. The study, led by Gordon Smith from the University of Cambridge, found that abortion was a strong risk factor for subsequent preterm birth in the 1980s but over the next 20 years, the link progressively weakened and was no longer present among women giving birth from 2000 onwards. These findings are important as the current recommendations ...

Implementing smoke-free laws and increased tobacco taxes in India would yield substantial and rapid health benefits by averting future cardiovascular disease (CVD) deaths, according to a new study published this week in PLOS Medicine. The results of this study, conducted by Sanjay Basu and colleagues of Stanford University, USA, suggest that specific tobacco control strategies would be more effective than others for the reduction of CVD deaths over the next decade in India and possibly in other low- and middle-income countries. Cardiovascular diseases are conditions that ...

New interventional cardiac catheterization services offered by U.S. hospitals generally duplicate existing programs and do not help patients gain access to timely emergency cardiac care, according to a new study. Examining new cardiac catheterization programs nationally from 2004 to 2008, researchers found the programs were most likely to be introduced in areas that had existing services, near populations that had higher rates of private health insurance and in states where there is little oversight of hospitals. The findings are published online by the journal Circulation: ...

BUFFALO, N.Y. – The idea that females are more resilient than males in responding to stress is a popular view, and now University at Buffalo researchers have found a scientific explanation. The paper describing their embargoed study will be published July 9 online, in the high-impact journal, Molecular Psychiatry. "We have examined the molecular mechanism underlying gender-specific effects of stress," says senior author Zhen Yan, PhD, a professor in the Department of Physiology and Biophysics in the UB School of Medicine and Biomedical Sciences. "Previous studies have ...

A new study has shed light on the potential of birds to survive in the face of climate change. In the analysis, based on more than fifty years' detailed study of a population of great tits near Oxford, UK, a team of scientists were able to make predictions about how the birds could cope with a changing climate in the future. They found that for small, short-lived birds like the great tit, evolution can work fast enough for genetic adaptation to keep pace with a changing environment. However, even for such fast-evolving species, evolution on its own is not enough. By studying ...

Sexual reproduction is costly to those organisms that depend on it, like humans. For starters, only half of the population can bear offspring and the other half has to work hard to make sure they're included in the future gene pool. The payoff is that sexual reproduction allows the mixing of parental genomes to generate potentially beneficial new combinations of gene variants that had not previously coexisted on the same strand of DNA, or to separate beneficial mutations from detrimental ones. In contrast, bacteria reproduce by asexual reproduction—this is more efficient ...

Pre-eclampsia affects 3-5% of pregnant women and can lead to preterm delivery, prematurity, perinatal morbidity and mortality. Although preterm birth and low birth weight are associated with excess risk of CP, the causes remain largely unknown. Some studies have found an excess risk of CP in children born at term from mothers with pre-eclampsia while others have reported no association. Researchers from Norway therefore tested the hypothesis that pre-eclampsia poses a risk of CP in preterm and small babies. This is the first study to report that the association between ...
