A study led by a researcher from Plymouth University in the UK, has discovered that the inhibition of a particular mitochondrial fission protein could hold the key to potential treatment for Parkinson's Disease (PD). The findings of the research are published today, 5th November 2014, in Nature Communications. PD is a progressive neurological condition that affects movement. At present there is no cure and little understanding of why some people get the condition. In the UK one on 500 people, around 127,000, have PD. The debilitating movement symptoms of the disease ...

ANN ARBOR, Mich. — Millions of people with diabetes take medicine to ease the shooting, burning nerve pain that their disease can cause. And new research suggests that no matter which medicine their doctor prescribes, they'll get relief. But some of those medicines cost nearly 10 times as much as others, apparently with no major differences in how well they ease pain, say a pair of University of Michigan Medical School experts in a new commentary in the Annals of Internal Medicine. That makes cost -- not effect -- a crucial factor in deciding which medicine ...

TALLAHASSEE, Fla. — A new study by a Florida State University researcher reveals that a new dietary supplement is superior to calcium and vitamin D when it comes to bone health. Over 12 months, Bahram H. Arjmandi, Margaret A. Sitton Professor in the Department of Nutrition, Food and Exercise Sciences and Director of the Center for Advancing Exercise and Nutrition Research on Aging (CAENRA) at Florida State, studied the impact of the dietary supplement KoACT® versus calcium and vitamin D on bone loss. KoACT is a calcium-collagen chelate, a compound containing ...

A child's ability to distinguish musical rhythm is related to his or her capacity for understanding grammar, according to a recent study from a researcher at the Vanderbilt Kennedy Center. Reyna Gordon, Ph.D., a research fellow in the Department of Otolaryngology and at the Vanderbilt Kennedy Center, is the lead author of the study that was published online recently in the journal Developmental Science. She notes that the study is the first of its kind to show an association between musical rhythm and grammar. Though Gordon emphasizes that more research will be necessary ...

VTT Technical Research Centre of Finland has developed an innovative magnetometer that can replace conventional technology in applications such as neuroimaging, mineral exploration and molecular diagnostics. Its manufacturing costs are between 70 and 80 per cent lower than those of traditional technology, and the device is not as sensitive to external magnetic fields as its predecessors. The design of the magnetometer also makes it easier to integrate into measuring systems. Magnetometers are sensors that measure magnetic fields or changes in magnetic fields. The kinetic ...

Although gluten-free foods are trendy among the health-conscious, they are necessary for those with celiac disease. But gluten, the primary trigger for health problems in these patients, may not be the only culprit. Scientists are reporting in ACS' Journal of Proteome Research that people with the disease also have reactions to non-gluten wheat proteins. The results could help scientists better understand how the disease works and could have implications for how to treat it. Armin Alaedini, Susan B. Altenbach and colleagues point out that celiac disease symptoms are triggered ...

Photosynthesis is one of the most important processes in nature. The complex method by which all green plants harvest sunlight and thereby produce the oxygen in our air is still not fully understood. Researchers have used DESY's X-ray light source PETRA III to investigate a photosynthesis subsystem in a near-natural state. According to the scientists led by Privatdozentin Dr. Athina Zouni from the Humboldt University (HU) Berlin, X-ray diffraction experiments on the so-called photosystem II revealed structures which were yet unknown. The results are published in the scientific ...

Many pollutants with the potential to meddle with hormones — with bisphenol A (BPA) as a prime example — are already common in the environment. In an effort to clean up these pollutants found in the soil and waterways, scientists are now reporting a novel way to break them down by recruiting help from nanoparticles and light. The study appears in the journal ACS Applied Materials & Interfaces. Nikhil R. Jana and Susanta Kumar Bhunia explain that the class of pollutants known as endocrine disruptors has been shown to either mimic or block hormones in animals, ...

This news release is available in Japanese. In an article published in Frontiers in Computational Neuroscience by Okinawa Institute of Science and Technology Graduate University's Professor Robert Sinclair, he suggests that there still is a place in science in modern times for the interpretation of results using rational numbers or simple ratios. In a time where supercomputers dominate scientific analysis, Prof. Sinclair argues that there is not enough attention being paid to the basic approaches to science of the past, which were able to profoundly illuminate our ...

JRC scientists have developed a new index to measure the magnitude of heat waves, in cooperation with colleagues from five research organisations. According to the index projections, under the worst climate scenario of temperature rise nearing 4.8⁰C, extreme heat waves will become the norm by the end of the century. Heat waves like the one that hit Russia in summer 2010, the strongest on record in recent decades, will occur as often as every two years in southern Europe, North and South America, Africa and Indonesia. The Heat Wave Magnitude Index is the first to ...

WASHINGTON, Nov. 5, 2014—A new handheld probe developed by a team of university and industry researchers in the Netherlands and France could give doctors powerful new imaging capabilities right in the palms of their hands. The imaging system, which is described in a paper published in The Optical Society's (OSA) open-access journal Optics Express, shrinks a technology that once filled a whole lab bench down to a computer screen and a small probe about the size of a stapler. The new device combines two imaging modalities: ultrasound and photoacoustics. Ultrasound ...

If you're inside, chances are you're breathing in low levels of indoor air pollution, a mix of volatile organic compounds and other gaseous substances that can accumulate in buildings and potentially make you sick. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, describes the latest in air-cleaning technology, including one approach based on a filter for the International Space Station. Mitch Jacoby, a senior correspondent with C&EN, writes that in recent years, scientists have been gaining a better understanding ...

COLUMBUS, Ohio – A new study reveals the secret of how some fashion and beauty magazines continue to attract devoted audiences, even though they glamorize super-thin models that would seem to taunt normal-sized women. The research suggests that some readers, rather than comparing themselves unhappily with the thin models, may derive "thinspiration": the belief that they can make themselves look just as attractive as the models they see in these magazines. But this is not any kind of positive inspiration, said Silvia Knobloch-Westerwick, author of the study and ...

Around 5,000 cases of DCIS, a condition where cancerous cells are contained within the milk ducts of the breast, are diagnosed each year in the UK, with two thirds diagnosed through breast screening. If left untreated, up to half of DCIS cases could progress into invasive breast cancer, but it is not possible to say which ones, so all women are offered treatment. This usually involves breast-conserving surgery (lumpectomy) and, to reduce the risk of the cancer returning, radiotherapy to kill any remaining cancer cells. However, even with treatment up to one in five ...

RICHLAND, Wash. – In the Pacific Northwest, young salmon must dodge predatory birds, sea lions and more in their perilous trek toward the ocean. Hydroelectric dams don't make the trip any easier, with their manmade currents sweeping fish past swirling turbines and other obstacles. Despite these challenges, most juvenile salmon survive this journey every year. Now, a synthetic fish is helping existing hydroelectric dams and new, smaller hydro facilities become more fish-friendly. The latest version of the Sensor Fish – a small tubular device filled with sensors ...

Since 1999, the conjecture by Asher Peres, who invented quantum teleportation, has piqued the interest of many scientists in the field. According to his hypothesis, the weakest form of quantum entanglement can never result in the strongest manifestation of the phenomenon. Today, a team of researchers from the University of Geneva (UNIGE), Switzerland, and the Hungarian Academy of Sciences have proven this conjecture to be false, thus solving one of the most famous problems in quantum information physics. This news was published in Nature Communications review. The physicist ...

Providence, RI— Results of a new study published in The American Journal of Managed Care show that the presence of a family caregiver during patient recruitment is associated with a greater rate of completion of a post hospital transitional care coaching intervention, particularly among men. Discharge is a crucial component of the hospitalization process. Patients' understanding and engagement in discharge plans greatly influence their experiences, health outcomes, such as hospital readmission, and overall costs. The study looked at discharges using the Care Transitions ...

There's more to the decline of the once mighty ancient Assyrian Empire than just civil wars and political unrest. Archaeological, historical, and paleoclimatic evidence suggests that climatic factors and population growth might also have come into play. This is the opinion of Adam Schneider of the University of California-San Diego in the US, and Selim Adali of the Research Center for Anatolian Civilizations in Turkey, published in Springer's journal Climatic Change. In the 9th century BC, the Assyrian Empire of northern Iraq relentlessly started to expand into most of ...

Washington, DC (November 5, 2014) – Since the 1920s, scholars and politicians have blamed violence in movies and other media as a contributing factor to rising violence in society. Recently the responses to mass shootings in Aurora, CO and at Sandy Hook Elementary followed this theme as media consumption came into the equation. But can consumption of violent media really be a factor in real-world violence? A recent study published in the Journal of Communication by a researcher at Stetson University found that there were no associations between media violence consumption ...

For years, a multidisciplinary team of Johns Hopkins researchers has tracked an elusive creature, a complex of proteins thought to be at fault in some cases of sudden cardiac death. As they report Nov. 5 in the online edition of Nature Communications, they have finally captured images of the complex. Those images reveal the connection between some genetic mutations and electrical abnormalities of the heart and provide a starting point for designing therapies. Sudden cardiac death is often caused by conditions that affect electrical signaling in the heart. Genetic studies ...

Berlin, Germany (November, 2014) – Reconstructing ancient life has long required a certain degree of imagination. This is especially true when considering the coloration of long-extinct organisms. However, new methods of investigation are being incorporated into paleontology that may shed light (and color) on fossils. Research presented at the recent Society of Vertebrate Paleontology meeting shows the importance of using new imaging technologies in reconstructing the color of Archaeopteryx, one of the most famous and important fossils species. Ryan Carney of Brown ...

Berlin, Germany (November, 2014) – Unexpectedly one of the largest diamond mines in Africa, Catoca in Angola, holds 118 million year old dinosaur, crocodile and large mammal tracks. The mammal tracks show a raccoon-sized animal, during a time when most were no larger than a rat. Nearly 70 distinct tracks were recovered in the Catoca mine in Angola. All the tracks were found in a small sedimentary basin, formed about 118 Ma, during the Early Cretaceous, in the crater of a kimberlite pipe. The most important of these finds are those whose morphology is attributable ...

SALT LAKE CITY, Nov. 5, 2014 – University of Utah engineers developed the first room-temperature fuel cell that uses enzymes to help jet fuel produce electricity without needing to ignite the fuel. These new fuel cells can be used to power portable electronics, off-grid power and sensors. A study of the new cells appears online today in the American Chemical Society journal ACS Catalysis. Fuel cells convert energy into electricity through a chemical reaction between a fuel and an oxygen-rich source such as air. If a continuous flow of fuel is provided, a fuel ...

While roses are red, and violets are blue, how exactly do flower colors change? In the case of penstemons, with over 200 species to choose from, scientists Carolyn Wessinger and Mark Rausher have now shown that turning their flowers from blue to red involves knocking out the activity of just a single enzyme involved in the production of blue floral pigments. A genetically conserved biochemical pathway produces the vivid blue pigments that they found to mutate over time to produce red. To shift into red pigment production, the enzyme flavonoid 3', 5' –hydroxylase ...

MANY patients whose lung cancer is diagnosed as an emergency in hospital reported difficulties in previously seeing their GP, according to research presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool today (Tuesday). The study, carried out by researchers from the London Cancer Alliance (LCA) and King's College London, investigated around 130 patients who were diagnosed with lung cancer after attending as an emergency at one of seven hospitals in south and west London. Overall, nearly half of the patients reported that something ...
