Potentially worrisome weight gains following tonsillectomy occur mostly in children under the age of 6, not in older children, a study by Johns Hopkins experts in otolaryngology- head and neck surgery shows. Sudden increases in body mass index, or BMI, have been routinely observed for months after some of the more than half-million surgeries performed annually in the United States to remove the sore and swollen tissues at the back of the throat. The Johns Hopkins study, in 115 children in the Baltimore region, is believed to be the first to dispel long-held beliefs ...

The Pencil Nebula is pictured in a new image from ESO's La Silla Observatory in Chile. This peculiar cloud of glowing gas is part of a huge ring of wreckage left over after a supernova explosion that took place about 11 000 years ago. This detailed view was produced by the Wide Field Imager on the MPG/ESO 2.2-metre telescope. Despite the tranquil and apparently unchanging beauty of a starry night, the Universe is far from being a quiet place. Stars are being born and dying in an endless cycle, and sometimes the death of a star can create a vista of unequalled beauty as ...

A number of environmental toxins pose considerable health threats to humans, and the heavy metal cadmium (Cd) ranks high on the list. Most of us are exposed to it through plant-derived foods such as grains and vegetables. Now, new research offers ways in which investigators can reduce the amount of Cd found in the food we eat, according to a review published online September 12th in the Cell Press journal Trends in Plant Science. "Cadmium is virtually everywhere in the environment, and it is taken up into the human body and bioaccumulates for decades in the kidney," ...

Baltimore, MD —You may think you have dinner all to yourself, but you're actually sharing it with a vast community of microbes waiting within your digestive tract. A new study from a team including Carnegie's Steve Farber and Juliana Carten reveals that some gut microbes increase the absorption of dietary fats, allowing the host organism to extract more calories from the same amount of food. Previous studies showed gut microbes aid in the breakdown of complex carbohydrates, but their role in dietary fat metabolism remained a mystery, until now. The research is published ...

LIVERMORE, Calif.— U.S. energy policy should simultaneously pursue security of its energy supply, economic stability and reduced environmental impacts, says a national poll of energy professionals jointly prepared by Sandia National Laboratories and OurEnergyPolicy.org. The findings of the national poll, "The Goals of Energy Policy," show that the vast majority — more than 85 percent — of the 884 energy professionals surveyed prefer policymaking that pursues all three goals at once. The poll asked the experts to allocate 100 points, representing a 100 percent policymaking ...

A new paper appearing in the September 2012 edition of the Bulletin of The American Ceramic Society for the first time provides a scientific explanation of why some glass cookware sold in the United States is more susceptible than others to "explosive" shattering and the possibility of exposing consumers to injury from flying glass shards. Clear glass baking dishes and pots are a staple in many households around the world and have been since they were first introduced in 1915 to consumers by the Corning Glass Works, which created the Pyrex brand name. The original Pyrex ...

PARSONS, W. Va., September 12, 2012 – Using old deeds and witness trees, a U.S. Forest Service scientist has created a glimpse of the composition of the forests that covered today's Monongahela National Forest before settlement and logging changed the landscape. "European Settlement-Era Vegetation of the Monongahela National Forest, West Virginia" describes how a Forest Service scientist and her West Virginia University colleague answered questions about the composition of early forests using a unique dataset. The dataset was built with original deeds, metes and bounds ...

Vegas, Monte Carlo, and Atlantic City draw people from around the world who are willing to throw the dice and take their chances. Researchers from the Technical University of Lodz, Poland, have spotted something predictable in the seemingly random throw of the dice. By applying chaos theory and some high school level mechanics, they determined that by knowing the initial conditions – such as the viscosity of the air, the acceleration of gravity, and the friction of the table – it should be possible to predict the outcome when rolling the dice. The researchers created ...

New research from the Hebrew University of Jerusalem shows that a carefully scheduled high-fat diet can lead to a reduction in body weight and a unique metabolism in which ingested fats are not stored, but rather used for energy at times when no food is available. The research was conducted by Prof. Oren Froy along with Prof. Zecharia Madar, research student Yoni Genzer and research fellow Dr. Hadas Sherman at the Institute of Biochemistry, Food Science and Nutrition, at the Hebrew University's Robert H. Smith Faculty of Agriculture, Food and Environment. The results ...

There is a growing need for better biomarkers that allow early detection of human diseases, especially cancer. The markers can improve primary prevention, diagnosis and prognosis of disease. Furthermore, it is possible to predict which ...

OTTAWA, Canada, September 12, 2012—Vitamin D is increasingly being recognized as important for good health. Vitamin D is a hormone made in the skin following sun exposure or acquired from diet and supplement intake. Previous medical research has shown that low body levels of vitamin D make people more susceptible to problems such as bone fractures, poor mental health and infections like the common cold. Until recently, there had been little consideration given to the role of vitamin D in more severe diseases, which is why Dr. Dayre McNally's recent publication in the esteemed ...

CINCINNATI – New research indicates marijuana-like compounds called endocannabinoids alter genes and biological signals critical to the formation of a normal placenta during pregnancy and may contribute to pregnancy complications like preeclampsia. A study in the Sept. 14 edition of The Journal of Biological Chemistry offers new evidence that abnormal biological signaling by endocannabinoid lipid molecules produced by the body disrupts the movement of early embryonic cells important to a healthy pregnancy, in particular trophoblast cells that form the placenta. Abnormal ...

Businesses perform a large share of their research and development in a small number of geographic areas, two of the largest being the San Jose-San Francisco-Oakland area and the New York-Newark-Bridgeport area. In these two areas alone, designated as combined statistical areas (CSAs) by the Office of Management and Budget, companies performed at least $29.3 billion of R&D, according to a recent National Science Foundation report. Data are from the 2008 Business R&D and Innovation Survey (BRDIS). These new BRDIS data allow policymakers and researchers to explore patterns ...

Helicoverpa armigera: a global pest Larvae of the cotton bollworm (Helicoverpa armigera) are dreaded pests all over the world. They have a very wide host range: About 200 different plant species are known as potential food for the voracious insect. The herbivore attacks crops in Africa, South Europe, India, Central Asia, New Zealand, and Australia. Nearly 30% of all globally used insecticides − Bt toxins as well as pyrethroids − are applied to protect cotton and other crops against the bollworm. Resistance to pyrethroids Pyrethroids are synthetic substances ...

In an advance toward development of a nasal spray that protects against infection with influenza and spread of the disease, scientists are reporting identification of a substance that activates the first-line defense system against infection inside the nose. They describe effects of a synthetic form of a natural substance found in bacterial cell walls in ACS' journal Molecular Pharmaceutics. David C. Jackson and colleagues explain that the body's so-called innate immune system forms a first-line defense system against respiratory diseases like influenza A — which causes ...

People in the United States took more prescription drugs than ever last year, with the number of prescriptions increasing from 3.99 billion (with a cost of $308.6 billion) in 2010 to 4.02 billion (with a cost of $319.9 billion) in 2011. Those numbers and others appear in an annual profile of top prescription medicines published in the journal ACS Chemical Neuroscience. Journal Editor-in-Chief Craig W. Lindsley analyzed data on 2011 drugs with a focus on medications for central nervous system (CNS) disorders. So-called antipsychotic medicines — including those used to ...

The distribution system piping in U.S. public water systems that rely on non-disinfected well water or "ground water" may be a largely unrecognized cause of up to 1.1 million annual cases of acute gastrointestinal illness (AGI), involving nausea, vomiting and diarrhea, scientists are reporting. Their study in ACS' journal Environmental Science & Technology concludes that such illnesses may become more of a problem as much of the nation's drinking water supply system continues to age and deteriorate. Frank J. Loge, Mark A. Borchardt and colleagues explain that more than ...

EAST LANSING, Mich. — The brutally repressive Soviet Union Vladimir Shlapentokh left behind 33 years ago may have opened its borders to the world, but today's Russia has become wracked with greed, corruption and mass emigration that threaten the nation's future. So argues Shlapentokh, a Michigan State University sociologist, in the academic journal Communist and Post-Communist Studies. "As Russia's plight shows, the assumption that openness and liberalization automatically promote democracy and guarantee it will function turned out to be wrong," Shlapentokh said. "It ...

WASHINGTON -- Glaciers in the eastern and central regions of the Himalayas appear to be retreating at accelerating rates, similar to those in other areas of the world, while glaciers in the western Himalayas are more stable and could be growing, says a new report from the National Research Council. The report examines how changes to glaciers in the Hindu Kush-Himalayan region, which covers eight countries across Asia, could affect the area's river systems, water supplies, and the South Asian population. The mountains in the region form the headwaters of several major ...

Many high-achieving students experience math anxiety at a young age — a problem that can follow them throughout their lives, new research at the University of Chicago shows. In a study of first- and second-graders, Sian Beilock, professor in psychology, found that students report worry and fear about doing math as early as first grade. Most surprisingly math anxiety harmed the highest-achieving students, who typically have the most working memory, Beilock and her colleagues found. "You can think of working memory as a kind of 'mental scratchpad' that allows us to 'work' ...

Philadelphia, PA, September 12, 2012 – Glucocorticoids, a group of hormones that includes cortisol, are considered stress hormones because their levels increase following stress. When their relationship to stress was first identified, it was shown that the release of cortisol prepared the body to cope with the physical demands of stress. Subsequently, high levels of cortisol were linked to depression and other stress-related disorders, giving rise to the hypothesis that high levels of cortisol on a long-term basis may impair the psychological capacity to cope with stress. ...
