Nicotinoid, fungal disease team up to break down termites' tough defenses Posted: 20 May 2015 04:41 PM PDT |
Metabolic abnormalities may increase cardiovascular risk more in black women than white women Posted: 20 May 2015 04:39 PM PDT Large waistline, cholesterol disorders and other metabolic abnormalities may increase the relative risk of cardiovascular disease more among black women than among white women. Black women who were overweight or obese had elevated cardiovascular risk compared with normal weight black women even when they did not have metabolic abnormalities. White women who were overweight or obese, but did not have the metabolic syndrome had a cardiovascular risk similar to that of normal weight white women without the metabolic syndrome. |
Support group, home exercise improves mobility for peripheral artery disease patients Posted: 20 May 2015 04:39 PM PDT Group therapy that encourages walking at home improves and prevents mobility loss among patients with clogged arteries in the legs, a study concludes. Clogged arteries in the legs can cause pain and fatigue while walking. Maintaining mobility is integral to preserving functional independence, social interactions and daily activities. |

International study reveals that cold weather kills far more people than hot weather Posted: 20 May 2015 04:38 PM PDT Cold weather kills 20 times as many people as hot weather, according to an international study analyzing over 74 million deaths in 384 locations across 13 countries. The findings also reveal that deaths due to moderately hot or cold weather substantially exceed those resulting from extreme heat waves or cold spells. |
Surviving harsh environments becomes a death-trap for specialist corals Posted: 20 May 2015 04:35 PM PDT |
Online safety: If you want something done right, do it yourself Posted: 20 May 2015 01:03 PM PDT |
Arctic ducks combine nutrients from wintering, breeding grounds to grow healthy eggs Posted: 20 May 2015 01:03 PM PDT It takes a lot of nutrients to build an egg. One of the big questions among researchers who study the eggs of migratory birds is where those nutrients come from -- does the mother make the egg directly out of what she eats during the breeding season, or does she save up nutrients consumed on her wintering grounds? The answer appears to be both for Common Eiders, large, sea-going ducks that breed in the Arctic. |
Inexpensive way to manufacture nanofibers Posted: 20 May 2015 01:03 PM PDT |
Drinking chamomile decreases risk of death in older Mexican American women Posted: 20 May 2015 01:03 PM PDT Drinking chamomile tea was associated with a decreased risk of death from all causes in Mexican-American American women over 65, a new study has shown. Chamomile is one of the oldest, most-widely used and well-documented medicinal plants in the world and has been recommended for a variety of healing applications. It is currently widely used as an herbal remedy in Mexico and among Mexican-Americans. |
Analysis compares stent expansion achieved with guidance from OCT versus IVUS Posted: 20 May 2015 01:03 PM PDT Data from the ILUMIEN II trial found that guidance from optimal coherence tomography was associated with comparable stent expansion as guidance from intravascular ultrasound in patients undergoing percutaneous coronary intervention. Results from the study were presented today at EuroPCR 2015, the official annual meeting of the European Association for Percutaneous Cardiovascular Interventions. |
New studies contradict earlier findings on Rett syndrome Posted: 20 May 2015 01:03 PM PDT Bone marrow transplant does not rescue mouse models of Rett syndrome, a severe neurological disease that affects very young girls, a new study shows. The findings contradict seemingly promising results published in 2012, which initiated a clinical trial for human patients. Rett syndrome is caused by mutations in the X-linked MECP2 gene and affects about 1 in every 10,000 girls (it is most often fatal in boys at or near birth). Rett syndrome causes many disabilities, both intellectual and physical. |

Copd is independent risk factor for cardiovascular death, but not risk of stroke Posted: 20 May 2015 01:01 PM PDT Chronic obstructive pulmonary disease, or COPD, is associated with increased risk of dying from a cardiovascular disease such as heart failure or a heart attack, as well as diseases not associated with the heart. However, COPD is not by itself associated with increased likelihood of having a stroke or a systemic embolism, according to a new research study. |
Australian public not being informed about dangers of medical overdiagnosis Posted: 20 May 2015 12:16 PM PDT A national survey reveals that only one in ten Australians report being told about the risk of overdiagnosis by their doctors, according to research. The increasingly recognized problem of overdiagnosis happens when someone is diagnosed with a disease that will never cause them any harm, often as a result of healthy people being screened for diseases such as breast or prostate cancer. Overdiagnosis can be harmful due to unnecessary labeling and treatment. |
Acetaminophen in pregnancy may lower testosterone in unborn boys Posted: 20 May 2015 12:16 PM PDT |
Deepwater Horizon oil spill contributed to high number of Gulf dolphin deaths Posted: 20 May 2015 12:16 PM PDT |
First dinosaur fossil discovered in Washington state Posted: 20 May 2015 12:16 PM PDT |
Male Java sparrows may 'drum' to their songs Posted: 20 May 2015 12:16 PM PDT Male Java sparrows may coordinate their bill-clicking sounds with the notes of their song. Birds may communicate using both vocalizations and movement, as for instance occurs during courtship displays, but scientists' understanding of how they coordinate their movements with the sounds they produce is limited. To further investigate birds' communicative and musical abilities, the authors of this study looked into the vocalizations and bill sounds associated with singing in the Java sparrow, a song bird. |

Colorado's biggest storms can happen any time, study shows Posted: 20 May 2015 11:07 AM PDT In a state known for its dramatic weather and climate, Colorado's history of extreme precipitation varies considerably by season and location, according to a new study. Decision makers -- often facing increased pressure to consider climate change information -- typically turn to historical averages to understand when and where extreme rain, hail and snow happen in the state. But those averages often are not reliable because they're based on observations of events that don't happen frequently and because the observations themselves are limited, especially in remote areas, researchers say. |

Scientists reveal potential new drug target for the treatment of rheumatoid arthritis Posted: 20 May 2015 11:06 AM PDT A novel drug target for the treatment of rheumatoid arthritis has been identified, which focuses on the cells that are directly responsible for the cartilage damage in affected joints. Rheumatoid arthritis, an autoimmune disease that leads to stiff, deformed joints and often crippling pain, affects around 1.5 million adults in the United States. The immune system's attack on the body's own tissue leads to chronic, painful inflammation in the affected joints. |
Study reveals how eastern US forests came to be Posted: 20 May 2015 10:46 AM PDT Spring visitors to Great Smoky Mountains or the Blue Ridge Parkway will see ridges and valleys covered in flowering mountain laurels, rhododendrons, tulip poplars, dogwoods, black locusts and silverbell trees. A new study of nearly all the trees and shrubs in the southern Appalachians suggests that roughly half of the species can trace their relatives to thousands of miles away in Asia. Most of the rest likely arose within North America, the researchers say. |
How video gamers will be able to play in the cloud without guzzling gigabytes Posted: 20 May 2015 10:46 AM PDT Gamers might one day be able to enjoy the same graphics-intensive fast-action video games they play on their gaming consoles or personal computers from mobile devices such as smartphones and tablets without guzzling gigabytes, thanks to a new tool developed. Named 'Kahawai' after the Hawaiian word for stream, the tool delivers graphics and gameplay on par with conventional cloud-gaming, while using one sixth of the bandwidth. |
Resolving a lymphatic riddle: Researchers to grow, for the first time, lymphatic cells in the lab Posted: 20 May 2015 10:36 AM PDT For over one hundred years, scientists have debated the question of the origins of the lymphatic system -- a parallel system to the blood vessels that serves as a conduit for everything from immune cells to fat molecules to cancer cells. This debate is over, now that researchers have grown, for the first time, lymphatic cells in the lab. |
Supernova ignition surprises scientists Posted: 20 May 2015 10:36 AM PDT Scientists have captured the early death throes of supernovae for the first time and found that the universe's benchmark explosions are much more varied than expected.The scientists used the Kepler space telescope to photograph three type 1a supernovae in the earliest stages of ignition. They then tracked the explosions in detail to full brightness around three weeks later, and the subsequent decline over the next few months. |
Supernova collides with its companion star Posted: 20 May 2015 10:35 AM PDT Type Ia supernovae, one of the most dazzling phenomena in the universe, are produced when small dense stars called white dwarfs explode with ferocious intensity. At their peak, these supernovae can outshine an entire galaxy. Although thousands of supernovae of this kind were found in the last decades, the process by which a white dwarf becomes one has been unclear. |
World's oldest stone tools challenge ideas about first toolmakers Posted: 20 May 2015 10:35 AM PDT Scientists working in the desert of northwestern Kenya have found stone tools dating back 3.3 million years, long before the advent of modern humans, and by far the oldest such artifacts yet discovered. The tools push the known date of such tools back by 700,000 years; they also may challenge the notion that our own most direct ancestors were the first to bang two rocks together to create a new technology. |

Natural gas versus diesel: Examining the climate impacts of natural gas trucks Posted: 20 May 2015 08:43 AM PDT Some major trucking companies are turning to natural gas to fuel their fleets -- and to earn 'green' credit among customers. But celebrating lower emissions could be premature, according to a recent analysis. Researchers have found that converting heavy-duty trucks to run on natural gas could lead to negative climate impacts if steps are not taken to improve engine efficiency and reduce methane emissions from the fuel's supply chain. |
Include men in osteoporosis screening guidelines, experts urge Posted: 20 May 2015 08:43 AM PDT Osteoporosis affects more men than prostate cancer. In a large study of smokers, men were more likely than women to have osteoporosis and fractures of their vertebrae. Smoking history and chronic obstructive pulmonary disease (COPD) were independent risk factors for low bone density among both men and women. Researchers say screening for low vBMD by using QCT in men and women who are smokers will increase opportunities to identify and treat osteoporosis in this at-risk population. |

Do CEOs deserve all the attention they get? New research provides answers Posted: 20 May 2015 08:43 AM PDT |
One simple molecule regulates sexual behavior in Drosophila Posted: 20 May 2015 08:42 AM PDT Until now researchers have failed to identify the specific pheromone in Drosophila melanogaster that leads to mating success. Although the pheromones that inhibit mating in Drosophila were known, the positive pheromone signal that elicits courtship behavior and mating remained a mystery. Scientists have succeeded in identifying the molecule that regulates complex mating behavior in vinegar flies: a fatty acid methyl ester called methyl laurate. |
Amazing microdroplet structures may lead to new technologies Posted: 20 May 2015 08:42 AM PDT Unexpected shapes of mesoscale atoms -- structures built of microdroplets encapsulated within microdroplets -- have now been created. The discovery was possible with a new method for precise control over placement of tiny segments of liquid, one in another. With further progress in innovative microfluidic systems, the method may find use in medicine and materials science. |
