This news release is available in Spanish. Since 2006, the team of researchers has sequenced the mitochondrial DNA of all the known species of butterflies in the Iberian peninsula (228) and its main populations. The result is a report that compiles more than 3500 genetic sequences of all the species, which have been compared to the genetic sequences of other European populations. The paper has 277 pages of supplementary material, including pictures and 80 maps of the geographical distribution of the butterfly genetic lineages identified. This is the first time ...

(Philadelphia, PA) - Patients who have lower extremity proximal deep vein thrombosis (LE-DVT), or a blood clot in their leg, are increasingly undergoing minimally invasive catheter-based blood clot removal - also referred to as catheter-directed thrombolysis (CDT) - rather than solely being treated with traditional blood-thinning medications (anticoagulation alone). This trend is due to recent literature showing reductions in lifestyle-limiting post-thrombotic complications of acute DVT in patients who undergo CDT compared to those that are treated with anticoagulation ...

La Jolla, Calif., July 23, 2015 - A new study by researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP), the National Cancer Institute, and the Chulabhorn Research Institute has found that blocking the activity of a key immune receptor, the lymphotoxin-beta receptor (LTβR), reduces the progression of liver cancer. The results, published today in the online edition of Gut, could provide new treatment strategies for the disease, which is the third leading cause of cancer-related deaths worldwide. "Our findings point to a new way to improve the treatment ...

After decades of overtreatment for low-risk prostate cancer and inadequate management of its more aggressive forms, patients are now more likely to receive medical care matched to level of risk, according to a study by researchers at UC San Francisco. In the first study to document updated treatment trends, researchers found that from 2010 to 2013, 40 percent of men with low-risk prostate cancer opted for active surveillance, in which the disease is monitored closely with blood tests, imaging studies and biopsies. Treatment is deferred unless these tests show evidence ...

Today an international team of astronomers from NASA's Kepler mission have announced the discovery of a near-Earth-sized planet in the habitable zone of a Sun-like star. Dr Daniel Huber from the University of Sydney's School of Physics is part of the team which made the discovery with NASA's Kepler Space Telescope. The planet named Kepler-452b is 60 per cent larger than Earth and orbits a Sun-like star with an orbital period of 385 days. The mere 20 day difference between the planet's orbital period and that of Earth's makes it the closest analogue to Earth ever ...

EU's grid connected cumulative capacity in 2014 reached 129 GW, meeting 8% of European electricity demand, equivalent to the combined annual consumption of Belgium, the Netherlands, Greece and Ireland. According to a JRC report, the impressive growth of the industry will allow at least 12% electricity share by 2020, a significant contribution to the goal of the European energy and climate package of 20% share of energy from renewable sources. The 2014 JRC wind status report presents the technology, market and economics of the wind energy sector with a focus on the EU. ...

Scientists at the University of York believe they have identified how some tiny regulatory molecules in cells can make prostate cancers resistant to radiotherapy. It is hoped that this new development could pave the way for more effective treatments - allowing a lower dose of radiotherapy to be used while prolonging the lives of thousands of men. Prostate cancer is the most commonly diagnosed form of male cancer in the UK and kills more than 11,000 men every year. In the latest studies, published in European Urology and the British Journal of Cancer, scientists in The ...

July 24, 2015 - Patient satisfaction ratings after surgery for spinal degenerative disease--especially in terms of reduced pain and disability--are a good indicator of the procedure's effectiveness, reports a study in the August issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Wolters Kluwer. "Patient satisfaction with outcome may accurately represent the effectiveness of surgical spine care in terms of one-year improvement in pain and disability," according to the new research by Dr. Clinton J. Devin of Vanderbilt ...

It doesn't happen often that a young scientist makes a significant and unexpected discovery, but postdoctoral researcher Stephen Wu of the U.S. Department of Energy's Argonne National Laboratory just did exactly that. What he found--that you don't need a magnetic material to create spin current from insulators--has important implications for the field of spintronics and the development of high-speed, low-power electronics that use electron spin rather than charge to carry information. Wu's work upends prevailing ideas of how to generate a current of spins. "This is a ...

While all-inside techniques have many advantages, including shorter surgical time and reduced risk of damage to neurovascular tissues, potential drawbacks include risks of local soft-tissue irritation and implant migration or breakage. In particular, the "Watch" offers important tips for successfully using FAST-FIX meniscal-repair devices produced by Smith & Nephew. ...

Nailing the diagnosis of a psychiatric disorder may not be important in prescribing effective treatment, according to Mark Zimmerman, M.D., a clinical researcher at Rhode Island Hospital. His opinion editorial was published online today in the Journal of Clinical Psychiatry. "During the past 35 years, we have witnessed a revolution in the treatment of psychiatric disorders," said Zimmerman, director of outpatient psychiatry and the partial hospital program at Rhode Island Hospital and director of the Rhode Island Methods to Improve Diagnostic Assessment and Services ...

A new Animal Conservation study shows that sports stadium lighting can alter patterns of bat species activity and feeding, which may in turn have cascading effects on other organisms and the ecosystem as a whole. Using a novel field experiment, Dr. M. Corrie Schoeman demonstrates that urban exploiter bats are more likely to hunt insects attracted to bright light pollution sources such as stadiums than urban avoider bats. (Exploiter organisms can take advantage of food or resources supplied by humans, while avoider organisms have either a history of conflict with humans ...

In a recent year-long study, 40% of patients with chronic obstructive pulmonary disease (COPD) experienced falls, with more than 75% of these falling multiple times. Factors linked with an increased risk of falling included smoking, having other illnesses, taking multiple medications, having a fear of falling, and falling in the past. "The findings could be useful for developing preventative strategies," said Dr. Cristino Oliveira, lead author of the Respirology study. INFORMATION: ...

A computerized attention-control training program significantly reduced combat veterans' preoccupation with - or avoidance of -- threat and attendant PTSD symptoms. By contrast, another type of computerized training, called attention bias modification - which has proven helpful in treating anxiety disorders - did not reduce PTSD symptoms. NIMH and Israeli researchers conducted parallel trials in which the two treatments were tested in US and Israeli combat veterans. Daniel Pine, M.D., of the NIMH Emotion and Development Branch, Yair Bar-Haim, Ph.D., School of Psychological ...

Boston, MA -- More than 70% of pollen and honey samples collected from foraging bees in Massachusetts contain at least one neonicotinoid, a class of pesticide that has been implicated in Colony Collapse Disorder (CCD), in which adult bees abandon their hives during winter, according to a new study from Harvard T.H. Chan School of Public Health. The study will be published online July 23, 2015 in the Journal of Environmental Chemistry. "Data from this study clearly demonstrated the ubiquity of neonicotinoids in pollen and honey samples that bees are exposed to during ...

The over 50s who are 'successful agers'--healthy, active, sociable, and well off--are more at risk of harmful drinking than their less successful peers, concludes research published in the online journal BMJ Open. Harmful drinking is a "middle class phenomenon" which may be a hidden health and social problem in otherwise successful older people, warn the researchers, who call for explicit guidelines on alcohol consumption for this group. They base their findings on more than 9000 responses to the two most recent waves (2008-9 and 2010-11) of the English Longitudinal ...

Two new studies, both published in The Lancet, suggest that two different classes of drugs, aromatase inhibitors (AIs) and bisphosphonates, can each improve survival prospects for postmenopausal women with early breast cancer. Moreover, the researchers suggest that the two types of drug can be used together, increasing the benefits while also decreasing some side-effects. Most women are post-menopausal when they develop breast cancer, and breast cancer is usually found early, when surgery can remove all detectable disease, but might leave dangerous undetected micrometastases ...

A class of hormonal drugs called aromatase inhibitors substantially reduce the risk of death in postmenopausal women with the most common type of breast cancer, a major study of more than 30,000 women shows. The research underlines the importance of aromatase inhibitors in the treatment of oestrogen receptor (ER)-positive breast cancer - and shows they reduce risk of death by significantly more than the older hormonal treatment tamoxifen. The study, published in The Lancet today (Friday), is relevant to postmenopausal women with ER-positive breast cancer, which accounts ...

Highlight Proteins in the Wnt signaling pathway help drive kidney scarring that can lead to chronic kidney disease. Washington, DC (July 23, 2015) -- Chronic diseases such as diabetes and hypertension cause injury to the kidneys, which can lead to scarring and the development of chronic kidney disease. By identifying proteins important to this scarring process, researchers now point to a new strategy for possibly preventing kidney failure and the need for dialysis or transplantation in many patients. The findings appear in an upcoming issue of the Journal of the ...

MIAMI - New research reveals that some of the earliest civilizations in the Middle East and the Fertile Crescent may have been affected by abrupt climate change. These findings show that while socio-economic factors were traditionally considered to shape ancient human societies in this region, the influence of abrupt climate change should not be underestimated. A team of international scientists led by researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science found that during the first half of the last interglacial period known ...

A biomarker found in the blood of alcohol users is significantly higher in binge drinkers than in those who consume alcohol moderately, according to a study by researchers at the University of Illinois at Chicago. The biomarker, called phosphatidylethanol (PEth), could be used to screen young adults for harmful or heavy drinking such as binge drinking. Having performed extensive research on alcohol and its effects on health throughout her career, Mariann Piano, professor and head of the department of biobehavioral health science in the UIC College of Nursing, knew PEth ...

With the flick of a tiny mechanical wrist, a team of engineers and doctors at Vanderbilt University's Medical Engineering and Discovery Laboratory hope to give needlescopic surgery a whole new degree of dexterity. Needlescopic surgery, which uses surgical instruments shrunk to the diameter of a sewing needle, is the ultimate form of minimally invasive surgery. The needle-sized incisions it requires are so small that they can be sealed with surgical tape and usually heal without leaving a scar. Although it's been around since the 1990s, the technique, which is also called ...

NEW YORK, NY (July 23, 2015)--Researchers at Columbia University Medical Center (CUMC) have developed a computer algorithm that is helping scientists see how drugs produce pharmacological effects inside the body. The study, published in the journal Cell, could help researchers create drugs that are more efficient and less prone to side effects, suggest ways to regulate a drug's activity, and identify novel therapeutic uses for new and existing compounds. "For the first time we can perform a genome-wide search to identify the entire set of proteins that play a role in ...

SPOKANE, Wash. - Pharmaceutical sciences researchers at Washington State University have discovered a protein's previously unknown role in cell division. The well known protein ATF5, or Activating Transcription Factor 5, controls how often specific genes are expressed, or copied from DNA. ATF5 regulates genes that control cell survival. But the research team has identified a part this protein is playing that is not related to its transcription factor role. Within the part of the cell called the centrosome, ATF5 is also acting as a structural protein. Structural ...
