Bacteria manipulate salt to build shelters to hibernate
http://www.mybiologica.com/wp-content/uploads/2014/07/38e8140725080316.jpg
For the first time, Spanish researchers have detected an unknown interaction between microorganisms and salt. When Escherichia coli cells are introduced into a droplet of salt water that is left to dry, bacteria manipulate the sodium chloride crystallisation to create biomineralogical biosaline 3-D morphologically complex formations, where they hibernate. Afterwards, simply by rehydrating the material, bacteria are revived. The discovery was made by chance with a home microscope, but it made the cover of the ‘Astrobiology’ journal and may help us find signs of life on other planets.The bacterium Escherichia coli is one of the most studied living forms by biologists, but none had to date noticed what this microorganism can do within a simple drop of salt water: create impressive biomineralogical patterns in which it shelters itself when it dries.”It was a complete surprise, a fully unexpected result, when I introduced E.. coli cells into salt water and I realised that the bacteria had the ability to join the salt crystallisation and modulate the development and growth of the sodium chloride crystals,” biologist Jos Mara Gmez said.”Thus, in around four hours, in the drop of water that had dried, an impressive tapestry of biosaline patterns was created with complex 3D architecture,” added the researcher, who made the discovery with the microscope in his house, although he later confirmed it with the help of his colleagues from the Laboratory of BioMineralogy and Astrobiological Research (LBMARS, University of Valladolid-CSIC), Spain.Until present, we knew of similar patterns created from saline solutions and isolated proteins, but this is the first report that demonstrates how whole bacterial cells can manage the crystallisation of sodium chloride (NaCl) and generate self-organised biosaline structures of a fractal or dendritic appearance. The study and the striking three-dimensional patterns are on the front cover of this month’s edition of Astrobiology.”The most interesting result is that the bacteria enter a state of hibernation inside these desiccated patterns, but they can later be ‘revived’ simply by rehydration,” said Gmez, who highlighted a very important result from an astrobiological point of view: “Given the richness and complexity of these formations, they may be used as biosignatures in the search for life in extremely dry environments outside our own planet, such as the surface of Mars or that of Jupiter’s satellite, Europa.”In fact, the LBMARS laboratory participates in the development of the Raman RLS instrument of the ExoMars rover, the mission that the European Space Agency (ESA) will send to the red planet in 2018, and this new finding may help them search for possible biological signs. According to the researcher, “the patterns observed will help calibrate the instrument and test its detection of signs of hibernation or traces of Martian life.””The challenge we now face is to understand how the bacteria control the crystallisation of NaCl to create these incredible 3D structures and vice-versa, how salt influences this action, as well as studying the structure of these microorganisms that withstand desiccation,” said Gmez, who reminds us that a simple curiosity and excitement about science, although it may be with simple means, still allows us to make some interesting discoveries: “This is a tribute to scientists such as the Spaniard Santiago Ramn y Cajal and the Dutch scientist Anton van Leeuwenhoek, who also worked from home with their own microscopes”Story Source:The above story is based on materials provided by Plataforma SINC.

Slow walking speed, memory complaints can predict dementia
http://feeds.feedburner.com/~ff/sciencedaily/top_news/top_health?d=Gqkty0xVXF4
A study involving nearly 27,000 older adults on five continents found that nearly 1 in 10 met criteria for pre-dementia based on a simple test that measures how fast people walk and whether they have cognitive complaints. People who tested positive for pre-dementia were twice as likely as others to develop dementia within 12 years. The study, led by scientists at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center, was published online on July 16, 2014 in Neurology, the medical journal of the American Academy of Neurology.The new test diagnoses motoric cognitive risk syndrome (MCR). Testing for the newly described syndrome relies on measuring gait speed (our manner of walking) and asking a few simple questions about a patient’s cognitive abilities, both of which take just seconds. The test is not reliant on the latest medical technology and can be done in a clinical setting, diagnosing people in the early stages of the dementia process. Early diagnosis is critical because it allows time to identify and possibly treat the underlying causes of the disease, which may delay or even prevent the onset of dementia in some cases.”In many clinical and community settings, people don’t have access to the sophisticated tests — biomarker assays, cognitive tests or neuroimaging studies — used to diagnose people at risk for developing dementia,” said Joe Verghese, M.B.B.S., professor in the Saul R. Korey Department of Neurology and of medicine at Einstein, chief of geriatrics at Einstein and Montefiore, and senior author of the Neurology paper. “Our assessment method could enable many more people to learn if they’re at risk for dementia, since it avoids the need for complex testing and doesn’t require that the test be administered by a neurologist. The potential payoff could be tremendous — not only for individuals and their families, but also in terms of healthcare savings for society. All that’s needed to assess MCR is a stopwatch and a few questions, so primary care physicians could easily incorporate it into examinations of their older patients.”The U.S. …

Climate Change Increases Risk of Crop Slowdown in Next 20 Years
http://www.mybiologica.com/wp-content/uploads/2014/07/d106140725144459.jpg
The world faces a small but substantially increased risk over the next two decades of a major slowdown in the growth of global crop yields because of climate change, new research finds.The authors, from Stanford University and the National Center for Atmospheric Research (NCAR), say the odds of a major production slowdown of wheat and corn even with a warming climate are not very high. But the risk is about 20 times more significant than it would be without global warming, and it may require planning by organizations that are affected by international food availability and price.”Climate change has substantially increased the prospect that crop production will fail to keep up with rising demand in the next 20 years,” said NCAR scientist Claudia Tebaldi, a co-author of the study.Stanford professor David Lobell said he wanted to study the potential impact of climate change on agriculture in the next two decades because of questions he has received from stakeholders and decision makers in governments and the private sector.”I’m often asked whether climate change will threaten food supply, as if it’s a simple yes or no answer,” Lobell said. “The truth is that over a 10- or 20-year period, it depends largely on how fast Earth warms, and we can’t predict the pace of warming very precisely. So the best we can do is try to determine the odds.”Lobell and Tebaldi used computer models of global climate, as well as data about weather and crops, to calculate the chances that climatic trends would have a negative effect of 10 percent on yields of corn and wheat in the next 20 years. This would have a major impact on food supply. Yields would continue to increase but the slowdown would effectively cut the projected rate of increase by about half at the same time that demand is projected to grow sharply.They found that the likelihood of natural climate shifts causing such a slowdown over the next 20 years is only 1 in 200. But when the authors accounted for human-induced global warming, they found that the odds jumped to 1 in 10 for corn and 1 in 20 for wheat.The study appears in this month’s issue of Environmental Research Letters. It was funded by the National Science Foundation (NSF), which is NCAR’s sponsor, and by the U.S. Department of Energy (DOE).More crops needed worldwideGlobal yields of crops such as corn and wheat have typically increased by about 1-2 percent per year in recent decades, and the U.N. Food and Agriculture Organization projects that global production of major crops will increase by 13 percent per decade through 2030 — likely the fastest rate of increase during the coming century. …

Experiences at every stage of life contribute to cognitive abilities in old age
http://www.mybiologica.com/wp-content/uploads/2014/07/7989140725110944.jpg
Early life experiences, such as childhood socioeconomic status and literacy, may have greater influence on the risk of cognitive impairment late in life than such demographic characteristics as race and ethnicity, a large study by researchers with the UC Davis Alzheimer’s Disease Center and the University of Victoria, Canada, has found.”Declining cognitive function in older adults is a major personal and public health concern,” said Bruce Reed professor of neurology and associate director of the UC Davis Alzheimer’s Disease Center.”But not all people lose cognitive function, and understanding the remarkable variability in cognitive trajectories as people age is of critical importance for prevention, treatment and planning to promote successful cognitive aging and minimize problems associated with cognitive decline.”The study, “Life Experiences and Demographic Influences on Cognitive Function in Older Adults,” is published online in Neuropsychology, a journal of the American Psychological Association. It is one of the first comprehensive examinations of the multiple influences of varied demographic factors early in life and their relationship to cognitive aging.The research was conducted in a group of over 300 diverse men and women who spoke either English or Spanish. They were recruited from senior citizen social, recreational and residential centers, as well as churches and health-care settings. At the time of recruitment, all study participants were 60 or older, and had no major psychiatric illnesses or life threatening medical illnesses. Participants were Caucasian, African-American or Hispanic.The extensive testing included multidisciplinary diagnostic evaluations through the UC Davis Alzheimer’s Disease Center in either English or Spanish, which permitted comparisons across a diverse cohort of participants.Consistent with previous research, the study found that non-Latino Caucasians scored 20 to 25 percent higher on tests of semantic memory (general knowledge) and 13 to 15 percent higher on tests of executive functioning compared to the other ethnic groups. However, ethnic differences in executive functioning disappeared and differences in semantic memory were reduced by 20 to 30 percent when group differences in childhood socioeconomic status, adult literacy and extent of physical activity during adulthood were considered.”This study is unusual in that it examines how many different life experiences affect cognitive decline in late life,” said Dan Mungas, professor of neurology and associate director of the UC Davis Alzheimer’s Disease Research Center.”It shows that variables like ethnicity and years of education that influence cognitive test scores in a single evaluation are not associated with rate of cognitive decline, but that specific life experiences like level of reading attainment and intellectually stimulating activities are predictive of the rate of late-life cognitive decline. This suggests that intellectual stimulation throughout the life span can reduce cognitive decline in old age.”Regardless of ethnicity, advanced age and apolipoprotein-E (APOE genotype) were associated with increased cognitive decline over an average of four years that participants were followed. APOE is the largest known genetic risk factor for late-onset Alzheimer’s. Less decline was experienced by persons who reported more engagement in recreational activities in late life and who maintained their levels of activity engagement from middle age to old age. Single-word reading — the ability to decode a word on sight, which often is considered an indication of quality of educational experience — was also associated with less cognitive decline, a finding that was true for both English and Spanish readers, irrespective of their race or ethnicity. …

Trees save lives, reduce respiratory problems
http://www.mybiologica.com/wp-content/uploads/2014/07/a027140725163557.jpg
In the first broad-scale estimate of air pollution removal by trees nationwide, U.S. Forest Service scientists and collaborators calculated that trees are saving more than 850 human lives a year and preventing 670,000 incidents of acute respiratory symptoms.While trees’ pollution removal equated to an average air quality improvement of less than 1 percent, the impacts of that improvement are substantial. Researchers valued the human health effects of the reduced air pollution at nearly $7 billion every year in a study published recently in the journal Environmental Pollution.The study by Dave Nowak and Eric Greenfield of the U.S. Forest Service’s Northern Research Station and Satoshi Hirabayashi and Allison Bodine of the Davey Institute is unique in that it directly links the removal of air pollution with improved human health effects and associated health values. The scientists found that pollution removal is substantially higher in rural areas than urban areas, however the effects on human health are substantially greater in urban areas than rural areas.”With more than 80 percent of Americans living in urban area, this research underscores how truly essential urban forests are to people across the nation,” said Michael T. Rains, Director of the Forest Service’s Northern Research Station and the Forest Products Laboratory. “Information and tools developed by Forest Service research are contributing to communities valuing and managing the 138 million acres of trees and forests that grace the nation’s cities, towns and communities.”The study considered four pollutants for which the U.S. EPA has established air quality standards: nitrogen dioxide, ozone, sulfur dioxide, and particulate matter less than 2.5 microns (PM2.5) in aerodynamic diameter. Health effects related to air pollution include impacts on pulmonary, cardiac, vascular, and neurological systems. In the United States, approximately 130,000 PM2.5-related deaths and 4,700 ozone-related deaths in 2005 were attributed to air pollution.Trees’ benefits vary with tree cover across the nation. …

Bothered by hot flashes? Acupuncture might be the answer, analysis suggests
http://feeds.feedburner.com/~r/sciencedaily/health_medicine/alternative_medicine/~4/xRd883w9miE
In the 2,500+ years that have passed since acupuncture was first used by the ancient Chinese, it has been used to treat a number of physical, mental and emotional conditions including nausea and vomiting, stroke rehabilitation, headaches, menstrual cramps, asthma, carpal tunnel, fibromyalgia and osteoarthritis, to name just a few. Now, a meta-analysis of randomized controlled trials which is being published this month in Menopause, the journal of The North American Menopause Society (NAMS), indicates that acupuncture can affect the severity and frequency of hot flashes for women in natural menopause.An extensive search of previous studies evaluating the effectiveness of acupuncture uncovered 104 relevant students, of which 12 studies with 869 participants met the specified inclusion criteria to be included in this current study. While the studies provided inconsistent findings on the effects of acupuncture on other menopause-related symptoms such as sleep problems, mood disturbances and sexual problems, they did conclude that acupuncture positively impacted both the frequency and severity of hot flashes.Women experiencing natural menopause and aged between 40 and 60 years were included in the analysis, which evaluated the effects of various forms of acupuncture, including traditional Chinese medicine acupuncture (TCMA), acupressure, electroacupuncture, laser acupuncture and ear acupuncture.Interestingly, neither the effect on hot flash frequency or severity appeared to be linked to the number of treatment doses, number of sessions or duration of treatment. However, the findings showed that sham acupuncture could induce a treatment effect comparable with that of true acupuncture for the reduction of hot flash frequency. The effects on hot flashes were shown to be maintained for as long as three months.Although the study stopped short of explaining the exact mechanism underlying the effects of acupuncture on hot flashes, a theory was proposed to suggest that acupuncture caused a reduction in the concentration of β-endorphin in the hypothalamus, resulting from low concentrations of estrogen. These lower levels could trigger the release of CGRP, which affects thermoregulation.”More than anything, this review indicates that there is still much to be learned relative to the causes and treatments of menopausal hot flashes,” says NAMS executive director Margery Gass, MD. “The review suggests that acupuncture may be an effective alternative for reducing hot flashes, especially for those women seeking non- pharmacologic therapies.”A recent review indicated that approximately half of women experiencing menopause-associated symptoms use complementary and alternative medicine therapy, instead of pharmacologic therapies, for managing their menopausal symptoms.Story Source:The above story is based on materials provided by The North American Menopause Society (NAMS).

Epigenetic changes can drive cancer, study shows
http://www.mybiologica.com/wp-content/uploads/2014/07/3c0d140726082322.jpg
Cancer has long been thought to be primarily a genetic disease, but in recent decades scientists have come to believe that epigenetic changes — which don’t change the DNA sequence but how it is ‘read’ — also play a role in cancer. In particular DNA methylation, the addition of a methyl group (or molecule), is an epigenetic switch that can stably turn off genes, suggesting the potential to cause cancer just as a genetic mutation can. Until now, however, direct evidence that DNA methylation drives cancer formation was lacking.Researchers at the USDA/ARS Children’s Nutrition Research Center at Baylor College of Medicine and Texas Children’s Hospital have now created a mouse model providing the first in vivo evidence that epigenetic alterations alone can cause cancer. Their report appears in the Journal of Clinical Investigation.”We knew that epigenetic changes are associated with cancer, but didn’t know whether these were a cause or consequence of cancer. Developing this new approach for ‘epigenetic engineering’ allowed us to test whether DNA methylation changes alone can drive cancer,” said Dr. Lanlan Shen, associate professor of pediatrics at Baylor and senior author of the study.Shen and colleagues focused on p16, a gene that normally functions to prevent cancer but is commonly methylated in a broad spectrum of human cancers. They devised an approach to engineer DNA methylation specifically to the mouse p16 regulatory region (promoter). As intended, the engineered p16 promoter acted as a ‘methylation magnet’. As the mice reached adulthood, gradually increasing p16 methylation led to a higher incidence of spontaneous cancers, and reduced survival.”This is not only the first in vivo evidence that epigenetic alteration alone can cause cancer,” said Shen. “This also has profound implications for future studies, because epigenetic changes are potentially reversible. …

Alternative to surgery for Graves" eye disease: Low-carb, gluten-free diet may help
http://feeds.feedburner.com/~r/sciencedaily/health_medicine/cosmetic_surgery/~4/GBsDdjuMKQA
Don Parker was facing a second surgery to treat the bulging eyes and double vision he was experiencing due to Graves’ eye disease.But then ophthalmologist James McDonnell, MD, of Loyola University Medical Center recommended an alternative therapy that did not involve surgery or medication.McDonnell told Parker to change his diet, lose weight and take a nutraceutical (natural food product) that’s designed to restore proper immune and digestive function.Parker followed McDonnell’s regimen. He lost more than 35 pounds by giving up soda pop and eating a low-carb, gluten-free diet with lots of vegetables. Each day, he takes 12 capsules of the nutraceutical.“My double vision is almost gone and there is so little bulging in my eyes that they look almost completely normal,” he said.Graves’ eye disease, also known as Graves’ ophthalmopathy, is present in about half of people who have Graves’ disease, an autoimmune disorder. In Graves’ eye disease, the immune system attacks muscles and other tissues around the eye. This can cause the eyes to bulge out and become misaligned.Bulging eyes can be treated with orbital decompression surgery. The surgeon removes bone and/or fat from behind the eye, allowing the eye to move back into its socket. Double vision can be treated with a different surgery, which straightens the eyes by adjusting the eye muscles.When Parker came to see McDonnell, he already had undergone one orbital decompression, and was facing a possible second surgery for his double vision. But rather than recommending surgery, McDonnell suggested a holistic approach.“Once you clear up and balance your body, a whole raft of problems can go away,” McDonnell said.Parker said his doctor’s appointment with McDonnell served as a wake-up call. “I was at a crossroads in my life,” Parker said. “I would have to either change my ways or die. …

Caffeine intake may worsen menopausal hot flashes, night sweats
http://feeds.feedburner.com/~r/sciencedaily/health_medicine/alternative_medicine/~4/ikL5a-3pewU
A new Mayo Clinic study, published online by the journal Menopause, found an association between caffeine intake and more bothersome hot flashes and night sweats in postmenopausal women. The study also showed an association between caffeine intake and fewer problems with mood, memory and concentration in perimenopausal women, possibly because caffeine is known to enhance arousal, mood and attention. The findings of this largest study to date on caffeine and menopausal symptoms are published on the Menopause website and will also be printed in a future issue of the journal.For the study, researchers conducted a survey using the Menopause Health Questionnaire, a comprehensive assessment of menopause-related health information that includes personal habits and ratings of menopausal symptom presence and severity. Questionnaires were completed by 2,507 consecutive women who presented with menopausal concerns at the Women’s Health Clinic at Mayo Clinic in Rochester between July 25, 2005, and July 25, 2011. Data from 1,806 women who met all inclusion criteria were analyzed. Menopausal symptom ratings were compared between caffeine users and nonusers.Approximately 85 percent of the U.S. population consumes some form of caffeine-containing beverage daily. Vasomotor symptoms (hot flashes and night sweats) are the most commonly reported menopausal symptoms, occurring in 79 percent of perimenopausal women and 65 percent of postmenopausal women. Although it has long been believed that caffeine intake exacerbates menopausal vasomotor symptoms, research has challenged this assumption, as caffeine has been both positively and negatively linked to hot flashes.”While these findings are preliminary, our study suggests that limiting caffeine intake may be useful for those postmenopausal women who have bothersome hot flashes and night sweats,” says Stephanie Faubion, M.D., director of the Women’s Health Clinic at Mayo Clinic in Rochester. “Menopause symptoms can be challenging but there are many management strategies to try.”Other strategies Dr. …

What has happened to the tsunami debris from Japan?
http://feeds.feedburner.com/~r/sciencedaily/top_news/top_science/~4/giLKrJMoOdY
The amount of debris in the ocean is growing exponentially, becoming more and more hazardous and harmful to marine life and therefore also to our ocean food source. Measuring and tracking the movements of such debris are still in their infancy. The driftage generated by the tragic 2011 tsunami in Japan gave scientists Nikolai Maximenko and Jan Hafner a unique chance to learn about the effects of the ocean and wind on floating materials as they move across the North Pacific Ocean.Shortly after the tsunami struck, Maximenko and Hafner used the IPRC Ocean Drift Model to predict where the debris from the tsunami would go. Their computer model is based on trajectories of real satellite-tracked drifting buoys and satellite-measured winds.The model has now been charting the possible paths of the tsunami driftage for nearly 3 years. The scientists have made a major improvement to the initial model: it now accommodates objects of different shapes and buoyancies that expose different amounts of surface to the wind and travel at different speeds and different trajectories. The model therefore now includes different levels of wind-forcing, simulating the movement of different types of floating debris.No formal marine debris observing systems exist to verify the model simulations. The model paths for tsunami debris, however, agree with reports of such debris washing up on the shores of Oregon, Washington, Alaska, and the Hawaiian Islands, as well as with observations by sailors crossing the North Pacific.The first physical evidence of tsunami driftage far from the coasts of Japan, for example, came in September 2011 from the Russian sail training ship Pallada. The captain had been forewarned that the ship might run into a tsunami debris field on its voyage from Honolulu to Vladivostok. Sailors, alerted and on the lookout, sighted much debris just northwest of Midway, and picked up a little fishing boat later confirmed lost in the tsunami.The model predicted both the timing and the type of material that has washed up along windward shores of Hawaii: the first tsunami driftage came in August — September 2012, about 1 years after the tragedy. These were very buoyant pieces, for example, oyster buoys, crates, small fishing boats like the one picked up by Pallada, and parts of small refrigerators.Then 2 years after the tsunami, materials sitting lower in the water and less buoyant than the previous driftage arrived: poles and beams with mortise and tenon features. …

Agricultural productivity loss a result of soil, crop damage from flooding
http://feeds.feedburner.com/~r/sciencedaily/plants_animals/agriculture_and_food/~4/dLjzFcY8Zag
The Cache River Basin, which once drained more than 614,100 acres across six southern Illinois counties, has changed substantively since the ancient Ohio River receded. The basin contains a slow-moving, meandering river; fertile soils and productive farmlands; deep sand and gravel deposits; sloughs and uplands; and one of the most unique and diverse natural habitats in Illinois and the nation.According to a recent University of Illinois study, the region’s agricultural lands dodged a bullet due to the timing of the great flood of April 2011 when the Ohio River approached the record high of 332.2 feet above sea level.“The floodwaters eventually drained back into the Ohio River and upper Mississippi River ultimately leaving approximately 1,000 acres of agricultural land flooded from a backup in the middle and lower Cache River Valley, which flooded the adjacent forest-covered alluvial soils and the slightly higher cultivated soils,” said U of I researcher Ken Olson.According to Olson, who has studied the effects of that particular flood extensively, these cultivated soils drained by the middle of June 2011 and were planted to soybeans. The floodwaters left a thin silt and clay deposition on the agricultural lands and crop residue when they receded. These coatings included significant amounts of soil organic carbon, microbes, and pathogens. After the coatings dried, they were incorporated into the topsoil layer of the alluvial soils using tillage equipment.“Because the flooding occurred during the non-growing season for corn and soybeans, the mixing in of sediment into the topsoil prior to planting resulted in little significant loss of soil productivity, little soybean damage, or yield reduction on lands outside the levees along the Mississippi, Cache, and Ohio rivers,” Olson said.As a result of the record Ohio River flood level, floodwaters passed north through the Post Creek cut-off, then west through the 2002 Karnak breach and into the middle Cache River valley to the Diversion to Mississippi River, which was already above flood stage so the floodwaters continued west. In late April, the Ohio River floodwaters then started to flood the towns of Olive Branch and Miller City, the Horseshoe Lake area, and surrounding agricultural lands. On May 2, 2011, the Len Small levee on the Mississippi River failed and resulted in the flooding of an additional 30,000 acres of Illinois public and private lands.Illinois agricultural statistics recorded the harvest of 4,500 fewer acres of corn and 6,500 fewer acres of soybeans in Alexander County in 2011. Soybean production was 1,200,000 bushels in 2010 but dropped to 865,000 bushels in 2011 due to flooding from both the Ohio and Mississippi rivers and crop and soil damage. The floodwaters also scoured lands in some places and deposited sand in other locations.Olson cautioned that, had winter wheat been planted outside the levees in the fall of 2010, the wheat crop would have drowned. “Illinois farmers are aware of the flooding potential, especially in the winter and early spring, so they don’t plant winter wheat on unprotected bottomlands,” he said. …

Despite a number of social/behavioral intervention and educational programs, the spread of hepatitis C (HCV) in people who inject drugs (PWIDs) remains a chronic problem. Now, researchers affiliated with New York University’s Center for Drug Use and HIV Research (CDUHR) are focusing on intervention strategies that highlight the lesser-known dangers of HCV transmission through the sharing of other injection equipment such as cookers, filters, drug-dilution water and water containers.Their article, “The Staying Safe Intervention: Training People Who Inject Drugs in Strategies to Avoid Injection-Related HCV and HIV Infection,” published in AIDS Education and Prevention, Vol. 26:2, April 15, 2014, explores the feasibility and efficacy of their “Staying Safe Intervention,” a strengths-based social/behavioral intervention conducted with small groups of PWID, designed to facilitate long-term prevention of HIV and HCV.”The Staying Safe Intervention seeks to reduce injection risk by intervening upstream in the causal chain of risk behaviors by modeling, training in, and motivating the use of strategies and practices of long-term risk-avoidance,” said Dr. Pedro Mateu-Gelabert, the study’s Principal Investigator, at the NYC-based National Development Research Institutes.Dr. Mateu-Gelabert and his NDRI-CDUHR team evaluated 68 street-recruited injectors from the Lower East Side of Manhattan. The objective was to reduce participants’ injection risk behaviors, empower and motivate behavioral change, and teach tactics to help reduce drug intake. The current program was built upon findings of their 2005 study, “Staying Safe,” which looked at the behaviors and strategies of individuals who had injected drugs for long periods of time (8-15 years) but had not contracted HIV or HCV.”The Staying Safe Intervention does not focus exclusively on the moment of injection,” explains Dr. Mateu-Gelabert, “but on the upstream determinants of risk behavior, such as stigma, risk networks, social support and income, while encouraging injectors to plan ahead in order to better manage the drug-related risk contexts they are likely to face.”The social/behavioral intervention showed substantial improvement in motivation and planning to avoid injection-related risks, increased use of stigma management strategies, and decreases in drug withdrawal episodes (known to reduce safe injection practices) and number of weekly injections. The research team also noted that participants in the study have been spreading the word on safer drug use within their communities.The Centers for Disease Control and Prevention estimate that not only do nine percent of new HIV infections originate from drug use, but 18 percent of PWID are HIV positive and up to 70-77 percent of PWIDs have HCV.”Given the substantial reductions observed among Staying Safe participants in key injection-related risk behaviors associated with HCV transmission, the Staying Safe Intervention may have the potential to contribute to sufficient additional risk reduction to help address the seemingly intractable rates of HCV transmission among PWID,” said Dr. Mateu-Gelabert.Currently, Dr. …

Temperature and ecology: Rival Chilean barnacles keep competition cool
http://feeds.feedburner.com/~r/sciencedaily/earth_climate/ecology/~4/4KH4zrlJiX4
Here are two facts that make the lowly barnacle important: They are popular models for ecology research, and they are very sensitive to temperature. Given that, the authors of a new study about a bellwether community of two barnacle species in Chile figured they might see clear effects on competition between these two species if they experimentally changed temperature. In the context of climate change, such an experiment could yield profound new insights into the biological future of a major coastline that is prized for its ecological, aesthetic, and economic values.But in the study to be printed in the April 2014 issue of the Journal of Experimental Marine Biology and Ecology, the scientists found no significant effect of temperature on competition at all. That surprising non-finding may have its own implications.”The dominant if somewhat dated narrative in marine ecology, and ecology more broadly, is that competition is a major structuring force in natural communities,” said co-author Heather Leslie, assistant professor of environmental studies and biology at Brown University. “We know it’s a more nuanced story, but to find cases where it’s a bit of a draw is really unusual.”Moreover, temperature did not turn out to be the mediating factor.”Temperature wasn’t the beast that we often think of it being, which in itself is surprising,” Leslie said.Plenty of studies of other co-occurring barnacles would have suggested otherwise. In the North Atlantic, there is a well-documented and clear dynamic between two barnacle species, the little gray barnacle (Chthamalus fragilis) and the northern rock barnacle (Semibalanus balanoides). The little gray barnacle can only survive high up on the rocks, where it is hottest and driest, because farther down it gets thoroughly routed by the northern rock barnacle. Temperature, in other words, provides the little gray’s only refuge.The picture in Chile was downright unclear. Previous studies had yielded conflicting hints about how temperature might affect the competition between two southern hemisphere barnacle species, Jehlius cirratus and Notochthalamus scabrosus. Led by Emily Lamb, who began the work as a Brown undergraduate concentrating in environmental science and is now a research assistant at the Estacin Costera de Investigaciones Marinas (ECIM) in Chile, the team devised an experiment to get a more definitive answer.Made in the shadeLike their northern cousins, the Chilean barnacles Jehlius and Notochthalamus live in a clearly stratified society with Jehlius more abundant higher up and Notochthalamus more abundant lower down into the tide. …
