Philadelphia, Pa. (November 12, 2012) – For elderly patients receiving home healthcare after a hospital stay, "social environmental factors"—particularly care provided by a family member or other informal caregiver—have a significant impact on the risk of repeated hospital admissions, reports a study in the October-December issue of Advances in Nursing Science. The journal is published by Lippincott Williams & Wilkins, a part ofWolters Kluwer Health. "Understanding how social environmental factors contribute to home healthcare patients being rehospitalized would be ...

LAGOS, Nigeria – Fifteen science academies of Africa issued a joint statement in Lagos, Nigeria, today calling on the African scientific community to intensify its study of the impact of climate change. Noting that Africa's contribution of scientific information to understanding climate change has been "meagre" to date, the statement calls for African researchers to step up their observation, modeling, and analyses of the effects of climate change on a regional scale, and to help plan interventions to mitigate and adapt to the impacts of climate change on the continent. ...

Philadelphia, PA—Scientists have estimated that there are 1.7 million species of animals, plants and algae on earth, and new species continue to be discovered. Unfortunately, as new species are found, many are also disappearing, contributing to a net decrease in biodiversity. The more diversity there is in a population, the longer the ecosystem can sustain itself. Hence, biodiversity is key to ecosystem resilience. Disease, destruction of habitats, pollution, chemical and pesticide use, increased UV-B radiation, and even the presence of new species are some of the causes ...

Children living in poorer neighborhoods are nearly 30 percent more likely to be obese than children in more affluent residences, according to a new study from Rice University. The study by Rice sociologists Rachel Tolbert Kimbro, director of the Kinder Institute for Urban Research's Urban Health Program, and Justin Denney, associate director of the program, reveals that living in neighborhoods with higher levels of poverty and lower levels of education is associated with increased child obesity risk, regardless of family composition or other individual factors. The research ...

The role that new low carbon technologies can play in helping the UK meet its targets for reducing greenhouse gas emissions and moving towards a green economy have been highlighted today with the publication of three in-depth reports into core areas of innovation. These three new analyses, Technology Innovation Needs Assessments (TINAs), cover non-domestic buildings, industrial emissions efficiency, and domestic buildings and are part of a series that spans 11 low carbon technology areas. The TINAs examine the potential for innovation in these technologies and assess the ...

EVANSTON, Ill. --- A new Northwestern University study shows the power of language in infants' ability to understand the intentions of others. As the babies watched intently, an experimenter produced an unusual behavior--she used her forehead to turn on a light. But how did babies interpret this behavior? Did they see it as an intentional act, as something worthy of imitating? Or did they see it as a fluke? To answer this question, the experimenter gave 14-month-old infants an opportunity to play with the light themselves. The results, based on two experiments, ...

Recommendations and decisions to use "least toxic pesticides" and "pesticides as a last resort" have flourished in the last decade, but according to three scientific organizations – the Weed Science Society of America (WSSA), the American Phytopathological Society (APS) and the Plant-Insect Ecosystems Section of the Entomological Society of America (P-IE ESA) – these are not the correct approaches to the pesticide component of an Integrated Pest Management (IPM) program. The three organizations have joined to take an objective look at the problems associated with "least ...

iFreedom Direct, a dedicated VA-approved lender serving military members, celebrates Veterans Day 2012 by debuting an informative new graphic on its two company websites and Facebook page. The infographic entitled Beyond Commander in Chief features a timeline of the 44 Presidents and their terms along with 24 headshots of those who served their country in the Armed Forces before calling the White House their home. Of course, George Washington started it all when he was named Commander in Chief of the Continental Army in 1775 -- even before being elected President. ...

Mental health experts from Meharry Medical College School of Medicine have released the first comprehensive report on the correlation between the incarceration of African American males and substance abuse and other health problems in the United States. Published in Frontiers in Psychology on the 12th of November, the report looks at decades of data concerning the African American population rates of incarceration and subsequent health issues. The authors conclude that the moral and economic costs of current racial disparities in the judicial system are fundamentally avoidable, ...

Child protection professionals are to be offered new guidance on how best to involve families in the case reviews that follow the death or serious injury of a child as a result of abuse or neglect. A report being launched today (Monday November 12) will reveal the results of a study led by experts at The University of Nottingham and commissioned by the British Association for the Study and Prevention of Child Abuse and Neglect (BASPCAN). The research explored the personal experiences of both professionals and families to make recommendations on best practice in this ...

MADISON — High levels of family stress in infancy are linked to differences in everyday brain function and anxiety in teenage girls, according to new results of a long-running population study by University of Wisconsin-Madison scientists. The study highlights evidence for a developmental pathway through which early life stress may drive these changes. Here, babies who lived in homes with stressed mothers were more likely to grow into preschoolers with higher levels of cortisol, a stress hormone. In addition, these girls with higher cortisol also showed less communication ...

China's endangered wild pandas may need new dinner reservations – and quickly – based on models that indicate climate change may kill off swaths of bamboo that pandas need to survive. In this week's international journal Nature Climate Change, scientists from Michigan State University and the Chinese Academy of Sciences give comprehensive forecasts of how changing climate may affect the most common species of bamboo that carpet the forest floors of prime panda habitat in northwestern China. Even the most optimistic scenarios show that bamboo die-offs would effectively ...

PHILADELPHIA - Fat cells store excess energy and signal these levels to the brain. In a new study this week in Nature Medicine, Georgios Paschos PhD, a research associate in the lab of Garret FitzGerald, MD, FRS director of the Institute for Translational Medicine and Therapeutics, Perelman School of Medicine, University of Pennsylvania, shows that deletion of the clock gene Arntl, also known as Bmal1, in fat cells, causes mice to become obese, with a shift in the timing of when this nocturnal species normally eats. These findings shed light on the complex causes of obesity ...

How can solar energy be stored so that it can be available any time, day or night, when the sun shining or not? EPFL scientists are developing a technology that can transform light energy into a clean fuel that has a neutral carbon footprint: hydrogen. The basic ingredients of the recipe are water and metal oxides, such as iron oxide, better known as rust. Kevin Sivula and his colleagues purposefully limited themselves to inexpensive materials and easily scalable production processes in order to enable an economically viable method for solar hydrogen production. The device, ...

ANN ARBOR—A thin, flexible electrode developed at the University of Michigan is 10 times smaller than the nearest competition and could make long-term measurements of neural activity practical at last. This kind of technology could eventually be used to send signals to prosthetic limbs, overcoming inflammation larger electrodes cause that damages both the brain and the electrodes. The main problem that neurons have with electrodes is that they make terrible neighbors. In addition to being enormous compared to the neurons, they are stiff and tend to rub nearby cells ...

An international group of scientists has identified three genetic regions that predispose Asian women who have never smoked to lung cancer. The finding provides further evidence that risk of lung cancer among never-smokers, especially Asian women, may be associated with certain unique inherited genetic characteristics that distinguishes it from lung cancer in smokers. Lung cancer in never-smokers is the seventh leading cause of cancer deaths worldwide, and the majority of lung cancers diagnosed historically among women in Eastern Asia have been in women who never smoked. ...

A novel miniature diagnostic platform using nuclear magnetic resonance (NMR) technology is capable of detecting minuscule cell particles known as microvesicles in a drop of blood. Microvesicles shed by cancer cells are even more numerous than those released by normal cells, so detecting them could prove a simple means for diagnosing cancer. In a study published in Nature Medicine, investigators at the Massachusetts General Hospital (MGH) Center for Systems Biology (CSB) demonstrate that microvesicles shed by brain cancer cells can be reliably detected in human blood through ...

SEATTLE – An international research team co-led by a scientist at Fred Hutchinson Cancer Research Center has identified two genetic factors behind the third most common form of muscular dystrophy. The findings, published online in Nature Genetics, represent the latest in the team's series of groundbreaking discoveries begun in 2010 regarding the genetic causes of facioscapulohumeral muscular dystrophy, or FSHD. The team, co-led by Stephen Tapscott, M.D., Ph.D., a member of the Hutchinson Center's Human Biology Division, discovered that a rare variant of FSHD, called type ...

Nobody knows the remarkable properties of human skin like the researchers struggling to emulate it. Not only is our skin sensitive, sending the brain precise information about pressure and temperature, but it also heals efficiently to preserve a protective barrier against the world. Combining these two features in a single synthetic material presented an exciting challenge for Stanford Chemical Engineering Professor Zhenan Bao and her team. Now, they have succeeded in making the first material that can both sense subtle pressure and heal itself when torn or cut. Their ...

This press release is available in German. Using the world's most powerful X-ray laser in California, an international research team discovered a surprising behaviour of atoms: with a single X-ray flash, the group led by Daniel Rolles from the Center for Free-Electron Laser Science (CFEL) in Hamburg (Germany) was able to kick a record number of 36 electrons at once out of a xenon atom. According to theoretical calculations, these are significantly more than should be possible at this energy of the X-ray radiation. The team present their unexpected observations in the ...

Scientists from the University of Hawaii at Manoa (UHM) published a study today in Nature Climate Change showing that besides marine inundation (flooding), low-lying coastal areas may also be vulnerable to "groundwater inundation," a factor largely unrecognized in earlier predictions on the effects of sea level rise (SLR). Previous research has predicted that by the end of the century, sea level may rise 1 meter. Kolja Rotzoll, Postdoctoral Researcher at the UHM Water Resources Research Center and Charles Fletcher, UHM Associate Dean, found that the flooded area in urban ...

(SALT LAKE CITY)—In a discovery that can fundamentally change how drugs for arthritis, and potentially many other diseases, are made, University of Utah medical researchers have identified a way to treat inflammation while potentially minimizing a serious side effect of current medications: the increased risk for infection. These findings provide a new roadmap for making powerful anti-inflammatory medicines that will be safer not only for arthritis patients but also for millions of others with inflammation-associated diseases, such as diabetes, traumatic brain injury, ...

Cold Spring Harbor, N.Y. – Flowers don't just catch our eyes, they catch those of pollinators like bees as well. They have to, in order to reproduce. Because plants need to maximize the opportunity for pollinators to gain access to their seeds, variations in the timing of flowering can have profound effects on flower, fruit, and seed production, and consequently agricultural yields. We know that the major driving forces of flowering are external factors such as light and temperature. However, new research from CSHL Assistant Professor Zach Lippman, Ph.D. and his collaborators, ...

A recent finding by medical geneticists sheds new light on how Facioscapulohumeral Muscular Dystrophy develops and how it might be treated. More commonly known as FSHD, the devastating disease affects both men and women. FSHD is usually an inherited genetic disorder, yet sometimes appears spontaneously via new mutations in individuals with no family history of the condition. "People with the condition experience progressive muscle weakness and about 1 in 5 require wheelchair assistance by age 40," said Dr. Daniel G. Miller, University of Washington associate professor ...

Researchers using the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have found a way to strip most of the electrons from xenon atoms, creating a "supercharged," strongly positive state at energies previously thought too low. The findings, which defy expectations and theory, could help scientists deliberately induce the high levels of damage needed to study extreme states of matter or ward off damage in samples they're trying to image. The results were reported this week in Nature Photonics. While the ...
