| Significant decline of genital warts in young women Posted: 20 Jul 2012 06:55 AM PDT The incidence of condyloma or genital warts (GW) is significantly declining in young women, according to a novel register study from Karolinska Institutet. The researchers suggest that this recent development may be explained by the introduction of the national HPV vaccine programme in Sweden. |
| ‘Seeds’ of Massive Black Holes Found at the Center of the Milky Way Galaxy Posted: 20 Jul 2012 06:49 AM PDT A research team at Keio University, led by Associate Professor Tomoharu Oka, has discovered intermediate-mass black hole (IMBH) candidates at the center of the Milky Way Galaxy. It is about 30,000 light-years from the solar system in the direction of Sagittarius. IMBH candidates are considered to be the "seeds" that form and grow massive black holes. |
| What 10,000 fruit flies have to tell us about differences between the sexes Posted: 20 Jul 2012 06:22 AM PDT What do you get when you dissect 10 000 fruit-fly larvae? A team of researchers led by the EMBL-European Bioinformatics Institute (EMBL-EBI) in the UK and the Max Planck Institute of Immunobiology and Epigenetics (MPI) in Germany has discovered a way in which cells can adjust the activity of many different genes at once. Their findings, published in the journal Science, overturn commonly held views and reveal an important mechanism behind gender differences. |
| Modifying surfaces by means of nanostructured reliefs to prevent the spread of bacteria Posted: 20 Jul 2012 06:17 AM PDT Researchers at the Institute for Agrobiotechnology (a mixed research centre set up by the Public University of Navarre, the CSIC-National Scientific Research Council, and the Government of Navarre) are designing, by means of laser application, nanostructured reliefs on surfaces so that they acquire antibacterial properties and are more resistant to the formation of bacterial biofilms. |
| Parkinson’s: newly discovered antibody could facilitate early diagnosis Posted: 20 Jul 2012 06:13 AM PDT Conditions such as Parkinson’s disease are a result of pathogenic changes to proteins. In the neurodegenerative condition of Parkinson’s disease, which is currently incurable, the alpha-synuclein protein changes and becomes pathological. Until now, there have not been any antibodies that could help to demonstrate the change in alpha-synuclein associated with the disease. An international team of experts led by Gabor G. Kovacs from the Clinical Institute of Neurology at the MedUni Vienna has now discovered a new antibody that actually possesses this ability. |
| Sorghum should be in the mix as a biofuel crop Posted: 19 Jul 2012 05:09 PM PDT Sweet and biomass sorghum would meet the need for next-generation biofuels to be environmentally sustainable, easily adopted by producers and take advantage of existing agricultural infrastructure, a group of researchers led by Purdue University scientists believes. |
| Probing the role of disorder in quantum coherence Posted: 19 Jul 2012 05:01 PM PDT A new experiment conducted at the Joint Quantum Institute (JQI) examines the relationship between quantum coherence, an important aspect of certain materials kept at low temperature, and the imperfections in those materials. These findings should be useful in forging a better understanding of disorder, and in turn in developing better quantum-based devices, such as superconducting magnets. |
| Anti-Tau Drug Improves Cognition, Decreases Tau Tangles in Alzheimer's Disease Models Posted: 19 Jul 2012 04:47 PM PDT While clinical trial results are being released regarding drugs intended to decrease amyloid production - thought to contribute to decline in Alzheimer's disease - clinical trials of drugs targeting other disease proteins, such as tau, are in their initial phases. |
| Modified tPA could be effective stroke treatment without bleeding risk Posted: 19 Jul 2012 04:39 PM PDT Even when its clot-dissolving powers are removed, the stroke drug tPA can still protect brain cells from the loss of oxygen and glucose induced by a stroke, researchers have discovered. |
| Novel Anti-Malarial Drug Target Identified Posted: 19 Jul 2012 04:25 PM PDT An international team of scientists, led by researchers from the Department of Pediatrics at the University of California, San Diego School of Medicine, have identified the first reported inhibitors of a key enzyme involved in survival of the parasite responsible for malaria. Their findings, which may provide the basis for anti-malarial drug development, are currently published in the online version of the Journal of Medicinal Chemistry. |
| Being in awe can expand time and enhance well-being Posted: 19 Jul 2012 04:18 PM PDT It doesn't matter what we've experienced – whether it's the breathtaking scope of the Grand Canyon, the ethereal beauty of the Aurora Borealis, or the exhilarating view from the top of the Eiffel Tower – at some point in our lives we've all had the feeling of being in a complete and overwhelming sense of awe. |
| Blood condition is highly predictive of graft failure in pediatric kidney transplant Posted: 19 Jul 2012 02:07 PM PDT For children receiving kidney transplants, a potentially correctable blood condition present in about one in four recipients is associated with a moderately increased risk of the graft's later failure, suggesting that clinicians should weigh whether transplant is advisable when the condition is present, according to UC Davis research presented today at the 24th International Congress of the Transplantation Society in Berlin. |
| New targeting technology improves outcomes for patients with atrial fibrillation Posted: 19 Jul 2012 02:02 PM PDT n a landmark study of atrial fibrillation, researchers from UCLA, UC San Diego and Indiana University report having found for the first time that these irregular heart rhythms are caused by small electrical sources within the heart, in the form of electrical spinning tops ("rotors") or focal beats. |
| Posted: 19 Jul 2012 01:56 PM PDT The powerful magnitude-8.6 earthquake that shook Sumatra on April 11, 2012, was a seismic standout for many reasons, not the least of which is that it was larger than scientists thought an earthquake of its type—an intraplate strike-slip quake—could ever be. Now, as Caltech researchers report on their findings from the first high-resolution observations of the underwater temblor, they point out that the earthquake was also unusually complex—rupturing along multiple faults that lie at nearly right angles to one another, as though racing through a maze. |
| Researchers develop rapid diagnostic test for pathogens, contaminants Posted: 19 Jul 2012 12:13 PM PDT Using nanoscale materials, researchers at the University of Georgia have developed a single-step method to rapidly and accurately detect viruses, bacteria and chemical contaminants. In a series of studies, the scientists were able to detect compounds such as lactic acid and the protein albumin in highly diluted samples and in mixtures that included dyes and other chemicals. Their results suggest that the same system could be used to detect pathogens and contaminants in biological mixtures such as food, blood, saliva and urine. |
| New Technique Reveals Cross-Talk Between Two Essential Cellular Processes Posted: 19 Jul 2012 10:25 AM PDT Scientists at The Scripps Research Institute have simultaneously mapped two of the most important types of protein-modification in cells, revealing their extensive cooperation during an essential cellular process. |
| Scripps Research Scientists Show Potent New Compound Virtually Eliminates HIV in Cell Culture Posted: 19 Jul 2012 10:22 AM PDT A new study by scientists on the Florida campus of The Scripps Research Institute shows, in cell culture, a natural compound can virtually eliminate human immunodeficiency virus (HIV) in infected cells. The compound defines a novel class of HIV anti-viral drugs endowed with the capacity to repress viral replication in acutely and chronically infected cells. |
| Despite Clear Benefits, Heart Failure Clinics Are Rarely Utilized Posted: 19 Jul 2012 09:35 AM PDT Outpatient heart failure (HF) clinics that provide patient education on ways to manage heart failure and risk factors, prescribe home-based exercises, and monitor therapy compliance have been shown to reduce morbidity, mortality, and health care costs. A new study published in the current issue of the Canadian Journal of Cardiology finds that despite guidelines that encourage physicians to recommend heart failure clinics, very few patients recently hospitalized with HF receive referrals or use one. |
| A good night's sleep could keep you out of a nursing home Posted: 19 Jul 2012 09:29 AM PDT Tired? Scientists have discovered another possible benefit of a night of restful and uninterrupted sleep. According to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health fragmented or interrupted sleep could predict future placement in a nursing home or assisted living facility. The study is featured in the July 2012 issue of the Journal of the American Geriatrics Society and outlines the association between objectively measured sleep and subsequent institutionalization among older women. |
| New melanoma mutations linked to sun Posted: 19 Jul 2012 09:19 AM PDT Cancer is a disease driven by genetic mutations. Melanoma, the deadliest form of skin cancer, displays the highest number of mutations, most of which bear the genetic signature of sun damage. |
