Jackie Speier (D-Calif.) and Rep. Jim McDermott ...

The seasonal influence of aerosols on Australia's tropical climate can now be included in climate models following completion of the first long-term study of fine smoke particles generated by burning of the savanna open woodland and grassland. Australia's biomass burning emissions comprise about eight per cent of the global total, ranking third by continent behind Africa (48 per cent) and South America (27 per cent). Lead researcher, CSIRO's Dr Ross Mitchell, said fine particles generated by burning of the tropical savanna of Northern Australia are a globally significant ...

Researchers from the Gene and Stem Cell Therapy Program at Sydney's Centenary Institute have confirmed that, far from being "junk", the 97 per cent of human DNA that does not encode instructions for making proteins can play a significant role in controlling cell development. And in doing so, the researchers have unravelled a previously unknown mechanism for regulating the activity of genes, increasing our understanding of the way cells develop and opening the way to new possibilities for therapy. Using the latest gene sequencing techniques and sophisticated computer ...

SAN FRANCISCO -- New evidence suggests the 1906 earthquake ruptured the San Andreas Fault in a single trace through Portola Village, current day Town of Portola Valley, and indicates a revised location for the fault trace. Portola Valley, south of San Francisco, has been extensively studied and the subject of the first geological map published in California. Yet studies have offered conflicting conclusions, caused in part by a misprinted photograph and unpublished data, as to the location and nature of the 1906 surface rupture through the area. "It is critical for ...

The future is looking good for drugs designed to combat Alzheimer's disease. EPFL scientists have unveiled how two classes of drug compounds currently in clinical trials work to fight the disease. Their research suggests that these compounds target the disease-causing peptides with high precision and with minimal side-effects. At the same time, the scientists offer a molecular explanation for early-onset hereditary forms of Alzheimer's, which can strike as early as thirty years of age. The conclusions of their research, which has been published in the journal Nature Communications, ...

Researchers from North Carolina State University have developed a new technique for creating devices out of a water-based hydrogel material that can be patterned, folded and used to manipulate objects.

Researchers at the University of Basel have successfully replaced the rare element iodine in copper-based dye-sensitized solar cells by the more abundant element cobalt, taking a step forward in the development of environmentally friendly energy production. The journal «Chemical Communications» has published the results of these so-called Cu-Co cells. Dye-sensitized solar cells (DSCs) transform light to electricity. They consist of a semiconductor on which a dye is anchored. This colored complex absorbs light and through an electron transfer process produces electrical ...

As any nervous first-time mother will confirm, the initial three months of pregnancy are the most risky time: many expectant women are reluctant to inform their friends or colleagues that they are pregnant until after this period is past. It is less well known that horses suffer from similar problems, with a considerable number of pregnancies failing to progress beyond the first five weeks. The explanation is still unclear but may relate to a problem with the mare's immune system, as the latest work in the group of Christine Aurich in the Vetmeduni's Centre for Artificial ...

New research into the fight against Dengue, an insect-borne tropical disease that infects up to 390 million people worldwide annually, may influence the development of anti-viral therapies that are effective against all four types of the virus. The findings, led by researchers at the University of Bristol and published in the Journal of Biological Chemistry today [2 August], show for the first time that there may be significant differences in specific properties of the viral proteins for the four dengue virus types. Due to the effects of globalisation, including increased ...

A study of gene expression led by scientists at the EMBL-European Bioinformatics Institute (EMBL-EBI) and the University of Cambridge has revealed the first steps of evolution in gene regulation in mice. Published in the journal Cell, the research has implications for the study of differences in gene regulation between people. "We found an impressive amount of variation between these apparently very similar mice in terms of transcription-factor binding, which is an important indicator of gene-regulation activity," says Paul Flicek of EMBL-EBI. "Often you'll see a specific ...

Lixisenatide (trade name: Lyxumia) has been approved in Germany since February 2013 for the treatment of type 2 diabetes mellitus in combination with oral blood-glucose lowering drugs or basal insulin when these, together with diet and exercise, do not provide adequate glycaemic control. In an early benefit assessment pursuant to the Act on the Reform of the Market for Medicinal Products (AMNOG), the German Institute for Quality and Efficiency in Health Care (IQWiG) examined whether this new drug offers an added benefit over the current standard therapy. No such added benefit ...

Researchers at the Max Planck Institute for Ornithology and the University of Lausanne have discovered that the sleeping patterns of baby birds are similar to that of baby mammals. What is more, the sleep of baby birds appears to change in the same way as it does in humans. Studying barn owls in the wild, the researchers discovered that this change in sleep is strongly correlated with the expression of a gene involved in producing dark, melanic feather spots, a trait known to covary with behavioral and physiological traits in adult owls. These findings raise the intriguing ...

Vandetanib (trade name: Caprelsa) has been approved in Germany since February 2012 for the treatment of adult patients who have a particular form of aggressive thyroid cancer. In a new benefit assessment, the German Institute for Quality and Efficiency in Health Care (IQWiG) has now examined the added benefit of the drug pursuant to the Act on the Reform of the Market for Medicinal Products (AMNOG). There is a hint that pain occurs later or gets worse later in a part of the patients, the ones aged under 65 years.But because of the overall poor data on side effects, no ...

August 2, 2013 / Kiel. How is vital oxygen supplied to the tropical ocean? For the first time, oceanographers at GEOMAR Helmholtz Centre for Ocean Research Kiel were able to make quantitative statements regarding this question. They showed that about one third of the oxygen supply in these areas is provided by turbulent processes, such as eddies or internal waves. The study, conducted in the framework of the Collaborative Research Center SFB 754 "Climate-Biogeochemistry Interactions in the Tropical Ocean", was just published in the international journal Biogeosciences.

Drexel University students will bring to light these and other findings about the plight, perils and peculiarities of the Northern Pine Snake in several presentations and posters at the Ecological Society of America annual meeting next week (ESA 2013), based on their research with Dr. Walt Bien's Laboratory of Pinelands Research in the New Jersey Pinelands. Northern pine snakes are charismatic ambassadors for the Pinelands National Reserve, an ecologically important ...

SAN ANTONIO -- Children's perceptions of living with asthma may differ significantly from their caregivers' perceptions, which means both should be interviewed when they visit the doctor's office, a new study from UT Kids San Antonio and the Center for Airway Inflammation Research (cAIR) shows. The study analyzed the agreement between 79 children and their caregivers on health-related quality-of-life questionnaires. The children ranged in age from 5 to 17. Fifty-three were classified as having acute asthma and 26 had refractory, or treatment-resistant, asthma. Include ...

BOZEMAN, Mont. – Within sight of the Trans-Canada Highway, a team of ecologists with the Western Transportation Institute at Montana State University set out on foot for a nearby site where they'd strung wire snags to catch the fur of passing bears. In the short distance they walked, with Canada's busiest transportation artery paralleling a prime patch of buffalo berries in the Bow River bottomland, the team spotted five grizzly bears, including a sow with two cubs. Since counting and genetically identifying bears was critical for Mike Sawaya, Tony Clevenger and Steven ...

WASHINGTON -- The United States lags behind other international plans to evaluate obesity prevention efforts, and the country needs to know whether these efforts are having their intended impact, says a new report from the Institute of Medicine. The committee that wrote the report concluded that more systematic and routine evaluations could help determine how well obesity prevention programs and policies are being implemented and which interventions work best. The committee also recommended specific national and community plans for evaluation of obesity prevention efforts. ...
