|  Multiple sclerosis drug shows promise for preventing heart failure  | A drug already approved to treat multiple sclerosis may also hold promise for treating cardiac hypertrophy, or thickening of the cardiac muscle -- a disorder that often leads to heart failure, researchers report. | Read More » Weight gain early in pregnancy means bigger, fatter babies  | A researcher cautions against too much weight early into pregnancy, which leads to larger, chubbier babies. | Read More » Rare fossil of late Cretaceous plesiosaur discovered  | Researchers have discovered the fossilized remains of an elasmosaur. A subgroup of the late Cretaceous plesiosaurs, the elasmosaurid plesiosaurs are recognized by their large body size and shape. This find is only the second elasmosaurid specimen containing more than one or two bones found in Alabama. | Read More » Step closer to custom-building new blood vessels  | Researchers have coaxed stem cells into forming networks of new blood vessels in the laboratory, then successfully transplanted them into mice. The stem cells are made by reprogramming ordinary cells, so the new technique could potentially be used to make blood vessels genetically matched to individual patients and unlikely to be rejected by their immune systems, the investigators say. | Read More » Ecological forces structure your body's personal mix of microbes  | Environmental conditions have a stronger influence on the mix of microbes living in your body than does competition between species. Instead of excluding each other, microbes that fiercely compete for similar resources are more likely to cohabit the same individual. The findings are a step toward building a predictive model of the human microbiome to study how medical conditions change this massive biological system, identify how to promote beneficial microbiomes, and design interventions for hard-to-manage problems like chronic digestive inflammation. | Read More » Steering stem cells with magnets  | By feeding stem cells tiny particles made of magnetized iron oxide, scientists can then use magnets to attract the cells to a particular location in the body. | Read More » Self-perpetuating signals may drive tumor cells to spread  | Scientists have identified a self-perpetuating signaling circuit inside connective tissue cells that allows these cells to form a front and a back and propel themselves in a particular direction over a long period of time. This propulsion is the same movement that tumor cells use to invade healthy tissue during cancer metastasis so cracking the code to this signaling network may lead to new therapeutic strategies. | Read More » Research supports mosquito indexing system that identifies best time to act against potential West Nile virus outbreaks  | Researchers have unlocked some of the mysteries of West Nile virus outbreaks and shown that use of a mosquito vector-index rating system works well to identify the best time for early intervention. | Read More » Predicting long-term success in college  | Long-term success in college may be better predicted with Advanced Placement (AP) exams and personality traits in combination with standard admission practices, according to new research. | Read More » Trade-offs between food security and climate change mitigation explored  | Improving agricultural productivity could help cut greenhouse gas emissions from agriculture, shows new research. But, sustainable farming methods are key. | Read More » Young children with autism benefit regardless of high-quality treatment model  | Researchers have found that preschoolers with autism spectrum disorder who receive high-quality early intervention benefit developmentally regardless of the treatment model used -- a surprising result that may have important implications for special-education programs and school classrooms across the country. | Read More » 'Brown ocean' can fuel inland tropical cyclones  | In the summer of 2007, Tropical Storm Erin stumped meteorologists. Most tropical cyclones dissipate after making landfall, weakened by everything from friction and wind shear to loss of the ocean as a source of heat energy. Not Erin. The storm intensified as it tracked through Texas. Erin is an example of a newly defined type of inland tropical cyclone that maintains or increases strength after landfall. Storms in the newly defined category derive their energy from the evaporation of abundant soil moisture -- a phenomenon that experts call the "brown ocean." | Read More » What are fructooliogosaccharides and how do they provide digestive, immunity and bone health benefits?  | New research has focused on the health benefits of short-chain fructooliogosaccharides (scFOS), which are low-calorie, non-digestible carbohydrates that can improve food taste and texture while aiding immunity, bone health and the growth and balance of important bacteria in the digestive track. | Read More » Taste rules for kids and healthy food choices  | Sweet and salty flavors, repeat exposure, serving size and parental behavior are the key drivers in children's food choices, according to new research. | Read More » Newly discovered flux in Earth may solve missing-mantle mystery  | Researchers have identified a "hidden flux" of material in the Earth's mantle that would make the planet's overall composition much more similar to that of meteorites. | Read More » Parasites change bees brains, but not their behavior  | Honey bees infected with the parasitic mite, Varroa destructor, or the microsporidia, Nosema ceranae, have changes in the chemical profile of their skin and in their brains. Despite this, parasitized bees were not expelled from the hive, which, the authors say, supports the hypothesis that stressed bees leave the hive altruistically to prevent the spread of infection. | Read More » Ripped apart by a black hole: Gas cloud makes closest approach to monster at center of Milky Way  | New observations show for the first time a gas cloud being ripped apart by the supermassive black hole at the centre of the galaxy. The cloud is now so stretched that its front part has passed the closest point and is traveling away from the black hole at more than 10 million km/h, whilst the tail is still falling towards it. | Read More » Family tree of fish yields surprises  | The mighty tuna is more closely related to the dainty seahorse than to a marlin or sailfish. That is one of the surprises from the first comprehensive family tree, or phylogeny, of the "spiny-rayed fish," a group that includes about a third of all living vertebrate species. | Read More » Discovery of a new class of white blood cells uncovers target for better vaccine design  | Scientists have discovered a new class of white blood cells in human lung and gut tissues that play a critical role as the first line of defense against harmful fungal and bacterial infections. This research will have significant impact on the design of vaccines and targeted immunotherapies for diseases caused by infectious microbes such as the hospital-acquired pneumonia. | Read More » Single dose of ADHD drug can reduce fall risk in older adults, study suggests  | A single dose of MPH improves walking by reducing the number of step errors and the step error rate in both single and dual tasks, a new study suggests. | Read More » Bird brain? Birds and humans have similar brain wiring  | You may have more in common with a pigeon than you realize, according to research. | Read More » Outgoing people lead happier lives  | Young adults who are more outgoing or more emotionally stable are happier in later life than their more introverted or less emotionally stable peers. | Read More » The key to ion beams' polarizability  | Polarizability determines the force with which an inhomogeneous external electric field acts on the ions of an ion beam. However, it can be quite tricky to obtain accurate values for this force. Now chemists have devised formulas providing the polarizability of atomic ions as a function of their total charge number. | Read More » Information in brain cells' electrical activity combines memory, environment, and state of mind  | The information carried by the electrical activity of neurons is a mixture of stored memories, environmental circumstances, and current state of mind, scientists have found in a study of laboratory rats. The findings offer new insights into the neurobiological processes that give rise to knowledge and memory recall. | Read More » Stop marine pollution to protect kelp forests  | Marine biologists have found that reducing nutrient pollution in coastal marine environments should help protect kelp forests from the damaging effects of rising CO2. | Read More » Deciphering butterflies' designer colors: Findings could inspire new hue-changing materials  | Scientists have uncovered how subtle differences in the tiny crystals of butterfly wings create stunningly varied patterns of color even among closely related species. The discovery could lead to new coatings for manufactured materials that could change color by design, if researchers can figure out how to replicate the wings' light-manipulating properties. | Read More » A lost frog in the lost world?  | Ecotourism and Conservation - Can it work? In the context of a study in the forests of Central Guyana, scientists investigated this very question and by chance found a previously undiscovered species of frog that only exists in a very confined area of the so-called Iwokrama Forest. | Read More » Chromosomal abnormalities may explain increased cancer risk in type 2 diabetes  | Certain chromosomal abnormalities of the preleukemic type appear to be over-represented in patients with type 2 diabetes (T2D) who are suffering from vascular complications. This finding may provide a partial explanation for the higher rates of cancer-related mortality observed among patients with this type of diabetes. | Read More » Injectable 'smart sponge' holds promise for controlled drug delivery  | Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core. The sponge expands and contracts in response to blood sugar levels to release insulin as needed. The technique could also be used for targeted drug delivery to cancer cells. | Read More » Monkey nation: Mainland Africa's most important nation for primates  | A five-year study gives new hope to some of the world's most endangered primates by establishing a roadmap to protect all 27 species in Tanzania – mainland Africa's most primate-diverse country. | Read More » Cost of treating dizziness in the emergency room soars  | Emergency room visits for severe dizziness have grown exponentially in recent years, with costs topping $3.9 billion in 2011 and projected to reach $4.4 billion by 2015. The investigators say roughly half a billion a year could be saved immediately if emergency room physicians stopped the routine and excessive use of head CT scans to search for stroke in dizzy patients, and instead used simple bedside physical exams to identify the small group of patients that truly needs imaging. | Read More » New Anagnorisma moth species from beautiful Binaloud Mountain Iran  | Researchers have described a new species of Noctuidae moth from Iran, which is the fifth described species of the genus Anagnorisma. The new species belongs to the owlet moths (family Noctuidae). which are a large worldwide group of more than 20,000 species of nocturnal lepidopterans. | Read More » Ghost particles: New limits on extremely rare decay  | Neutrinos are the most elusive particles having extremely weak interactions with all other particles. They have rather unusual properties and are even expected to be identical with their own antiparticles. So far this property is, however, not experimentally verified even though many studies of neutrinos over the last 60 years have already boosted our understanding of elementary particle physics. Now scientists have obtained new strong limits for the so-called neutrino-less double beta decay, which tests if neutrinos are their own antiparticles. | Read More » Monitoring nutrient intake can help vegetarian athletes stay competitive  | A balanced plant-based diet provides the same quality of fuel for athletes as a meat-based diet, provided vegetarians seek out other sources of certain nutrients that are more commonly found in animal products, according to new research. | Read More » | |
