NASA's Terra satellite passed over the central Alaska and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard captured an image of smoke and hot spots from the Funny River Fire in southern Alaska on May 26 at 21:45 UTC (5:45 p.m. EDT). The heat from the fire appears red in the imagery and the smoke appears light brown. On May 26 at 9:30 a.m. local time, the Alaska Interagency Incident Management Type 2 Team reported on the status of the fire through the multi-agency Incident Information System known as Inciweb. At that time the fire ...

GALVESTON —Researchers have concluded that providing better access to health care may lead to the overuse of mammograms for women who regularly see a primary care physician and who have a limited life expectancy. The cautionary note from researchers at the University of Texas Medical Branch at Galveston is that screening women in this category could subject them "to greater risks of physical, emotional and economic suffering." Dr. Alai Tan, a senior biostatistician in UTMB's Sealy Center on Aging and lead author of the study, said that "there has been little systematic ...

WASHINGTON D.C., May 27, 2014 -- It took every inch of the Large Hadron Collider's 17-mile length to accelerate particles to energies high enough to discover the Higgs boson. Now, imagine an accelerator that could do the same thing in, say, the length of a football field. Or less. That is the promise of laser-plasma accelerators, which use lasers instead of high-power radio-frequency waves to energize electrons in very short distances. Scientists have grappled with building these devices for two decades, and a new theoretical study predicts that this may be easier than ...

A new treatment for drug-resistant epilepsy with the potential to suppress seizures 'on demand' with a pill, similar to how you might take painkillers when you feel a headache coming on, has been developed by UCL (University College London) researchers funded by the Wellcome Trust. The treatment, described in Nature Communications, combines genetic and chemical approaches to suppress seizures without disrupting normal brain function. The technique was demonstrated in rodents but in future we could see people controlling seizures on-demand with a simple pill. Epilepsy ...

Butterflies and dragonflies with lighter colours are out-competing darker-coloured insects in the face of climate change. In a new study published in Nature Communications, scientists from Imperial College London, Philipps-University Marburg and University of Copenhagen have shown that as the climate warms across Europe, communities of butterflies and dragonflies consist of more lighter coloured species. Darker coloured species are retreating northwards to cooler areas, but lighter coloured species are also moving their geographical range north as Europe gets warmer. For ...

Climate changeButterflies and dragonflies with a lighter shade of colour do better in warmer areas of Europe. This gives them a competitive advantage over the darker insects in the face of climate change. Changes in Europe's insect assemblages due to warming can already be seen for dragonflies, shows a study recently published in Nature Communications. "When studying biodiversity, we lack general rules about why certain species occur where they do. With this research we've been able to show that butterfly and dragonfly species across Europe are distributed according to ...

Sexual inequality between boys and girls starts as early as in the mother's womb – but how and why this occurs could be a key to preventing higher rates of preterm birth, stillbirth and neonatal death among boys. A team from the University of Adelaide's Robinson Research Institute has been studying the underlying genetic and developmental reasons why male babies generally have worse outcomes than females, with significantly increased rates of pregnancy complications and poor health outcomes for males. The results - published today in the journal Molecular Human Reproduction ...

Removing a malignant tumor from the head of the pancreas is a risky and demanding operation. The surgeon must carefully navigate around the stomach, the gallbladder, the bile duct, lymph nodes, and several high-pressure blood vessels. But an inexpensive device designed by Harvard engineering students and a surgeon at Beth Israel Deaconess Medical Center offers surgeons a confident grip throughout the delicate procedure. The gentle grasper, equipped with rubberized pressure sensors, has three slender fingers that can slip through a very small incision and tease cancerous ...

The European Medicines Agency (EMA) receives comprehensive clinical study data from drug manufacturers. These data form the basis for the decision on the approval of new drugs. To make this information available to researchers and decision-makers, EMA issued a draft policy in 2013 for the publication of clinical study data, in which extensive data transparency was planned. Besides other interested parties, the German Institute for Quality and Efficiency in Health Care (IQWiG) was intensely involved in the subsequent consultations. The result of these consultations is ...

AUSTRALIA -- Predicted variations in global climates have fruit producers trying to determine which crops are best suited to weathering future temperature changes. Extreme high-temperature events are expected to become more frequent, and predictive models suggest that the global mean surface air temperature will rise by as much as two degrees by the middle of the 21st century. Higher temperatures could have an impact on the duration of critical "winter chill" periods needed for successful fruit production, potentially altering growing strategies. According to the authors ...

LJUBLJANA, SLOVENIA – The leaves and petals of roses are valued for their medicinal and aesthetic uses around the world. A new study identified specific phenolic compounds found in the petals of indigenous rose species and compared them with the phenolic profiles of modern rose cultivars to determine differences in the makeup of roses traditionally used for medicinal purposes and those varieties cherished for aesthetic qualities. According to the results, distinct differences exist in the distribution of leaf phenolic compounds, especially between indigenous rose species ...

A study published today in EMBO Molecular Medicine reveals that the loss of function of the gene RARRES3 in breast cancer cells promotes metastasis to the lung. The research, headed by Roger Gomis, ICREA Professor at the Institute for Research in Biomedicine (IRB Barcelona), is the result of a collaboration between two IRB labs and Joan Massagué, at the Memorial Sloan Kettering Cancer Center in New York. The scientists demonstrate that RARRES3 is suppressed in estrogen receptor-negative (ER-) breast cancer tumours, thus stimulating the later invasion of the cancer cells ...

In terms of ambience, Charlotte Central's cafeteria is -- well, conjure up your own elementary school lunch experience. There's more than one reason to run to recess. But on a recent visit to observe a group of researchers from UVM's Johnson Lab, the lunch ladies were serving up something more likely to be found on a restaurant menu: risotto with mushrooms and peas. It's the result of a host of programs by schools around Vermont to offer more tempting choices -- with locally sourced ingredients when possible, including herbs and vegetables from the playground garden -- ...

Scientists armed with a supercomputer and a vast trove of newly collected data on the body's most potent "tumor suppressor" gene have created the best map yet of how the gene works, an accomplishment that could lead to new techniques for fighting cancers, which are adept at disabling the gene in order to thrive. Scientists from the University of Colorado Cancer Center and the University of Colorado Boulder used a new technology to tease out how the p53 gene—which is responsible for recognizing damaged DNA in cells and then marking them for death—is actually able to suppress ...

This news release is available in French. Montreal, May 27, 2014 — Retail stores overflowing with merchandise can make consumers feel claustrophobic rather than ready to spend. But the recent move towards open, minimally stocked spaces can leave them feeling just as anxious. The solution to this shopping conundrum may be smell, as new research from Concordia University shows. In a study recently published in the American Journal of Business, researchers from the university's John Molson School of Business (JMSB) suggest that, when diffused in retail environments, ...

Imaging scientists at Western University's Robarts Research Institute (London, Canada) have developed a better way to track the progression of Multiple Sclerosis (MS) from its earliest stages. Led by Ravi Menon, PhD, the researchers used what's called "Quantitative Susceptibility (QS) Magnetic Resonance Imaging (MRI)," to measure damage in specific areas of the brain which the study showed to be common to all patients. The findings are published in advance online, in Radiology. "In MS research, there is something we call a clinical-radiological paradox. When ...

New Johns Hopkins research suggests that critically ill patients receiving steroids in a hospital's intensive care unit (ICU) are significantly more likely to develop delirium. Results of their research, they say, suggest minimizing the use of steroids could reduce delirium in the ICU. While it usually goes away after a few days, studies show delirium in the ICU has a long-term impact. It has been associated with worse functional recovery and cognitive impairments of a magnitude consistent with moderate traumatic brain injury or mild Alzheimer's disease. Overall, up ...

Heat shock protein (HSP90) has been suggested to be involved in neuronal protein misfolding and accumulation in Parkinson's disease (PD) brains leading to dopaminergic neuronal death and the eventual dopamine depletion. Therefore, HSP90 has been suggested as a therapeutic target in PD. Dr. Muhammed Al-Jarrah and co-workers from Jordan University of Science and Technology (JUST) point out exercise training significantly inhibited HSP90 overexpression in the soleus and gastrocnemius in PDe rats, which is a potential therapeutic target for ameliorating skeletal muscle abnormalities ...

Researchers at ITbM, Nagoya University developed a new nickel catalyst with a "Kabuto-like" structure that was found to catalyze the cross-coupling reaction between carbonyl compounds and readily available phenol derivatives, to form alpha-arylketones, which are found in many biologically active compounds (Kabuto = a helmet worn by Japanese samurai). Nagoya, Japan – Professors Kenichiro Itami and Junichiro Yamaguchi of the Institute of Transformative Bio-Molecules (WPI-ITbM) and graduate students Ryosuke Takise and Kei Muto of Nagoya University have succeeded in developing ...

A newly discovered tick-borne bacterium known as "Candidatus Neoehrlichia mikurensis" has been implicated in six cases of disease in Sweden. A new international study led by the Sahlgrenska Academy has shown that this bacterium is primarily a risk for people who are already sick and who are receiving immunosuppressive drugs. The Candidatus Neoehrlichia mikurensis bacterium, known in the medical world by its short name Neoehrlichia, was discovered and described for the first time in a scientific article in 2010. The bacterium, which is spread by rodents and ticks mainly ...

Environmental influences such as ionizing radiation, intense heat or various chemical substances damage the DNA constantly. Only thanks to efficient repair systems can mutations – changes in the DNA – largely be prevented. DNA crosslinks that covalently link both strands of the DNA double helix are among the most dangerous DNA lesions. Crosslinks block DNA replication and can thus cause cell death. Moreover, their faulty repair can trigger the development of tumors. Crosslink repair is highly complex and only vaguely understood today. A team of cancer researchers headed ...

As the team reports in the Investigative Radiology journal, this method shows promise in detecting diseases such as pulmonary emphysema at an earlier stage, than it is currently available. Conventional radiographic procedures generate images based on the absorption of X-rays as they pass through the tissue. The newly developed technique of X-ray dark-field radiography uses new technology to monitor wave changes during tissue transmission to create higher resolution images. Detailed images With the aid of this new technique, the team from the HMGU, KUM and TUM around Dr. ...

HOUSTON -- ( May 27, 2014 ) -- The suppression of two genes reduce breast cancer tumor formation and metastasis by interfering with blood vessel formation and recruitment, report scientists from Houston Methodist and five other institutions in the Proceedings of the National Academy of Sciences (now online). The findings may help medical researchers identify effective drug targets for triple negative breast cancer, or TNBC. The genes, MLF2 (myeloid leukemia factor 2) and RPL39 (a ribosomal protein), were found to most profoundly impact the production of nitric oxide synthase, ...

There are large numbers of entrepreneurs in developing countries who aren't registering their businesses with official authorities, hampering economic growth, according to new research. Shadow entrepreneurs are individuals who manage a business that sells legitimate goods and services but they do not register it. This means that they do not pay tax, operating in a shadow economy where business activities are performed outside the reach of government authorities. The shadow economy results in loss of tax revenue, unfair competition to registered businesses and also poor ...

This news release is available in German. Most terrestrial plants enter into biocoenosis with funghi. Both sides benefit: the fungus, which surrounds the small roots of the host plant with a thick felt, supplies the plant with trace elements and water. The plant, in turn, supplies the fungus with sugars and other metabolites which it is unable to produce itself. Toxic protein kills intestinal cells ETH researchers from the research group of microbiology professor Markus Aebi have discovered a protein in the cells of one such ectomycorrhizal fungus which offers an ...
