Urinary tract and sexually transmitted infections in women are misdiagnosed by emergency departments nearly half the time, according to a paper in the Journal of Clinical Microbiology, a publication of the American Society for Microbiology. These misdiagnoses result in overuse of antibiotics, and increased antibiotic resistance, according to Michelle Hecker, MD, an assistant professor in the Department of Medicine, Division of Infectious Diseases, MetroHealth Medical Center, Case Western Reserve University, Cleveland, and her collaborators. "Less than half the women ...

Astronomers using NASA's Hubble Space Telescope have discovered an immense cloud of hydrogen dubbed "The Behemoth" bleeding from a planet orbiting a nearby star. The enormous, comet-like feature is about 50 times the size of the parent star. The hydrogen is evaporating from a warm, Neptune-sized planet, due to extreme radiation from the star. This phenomenon has never been seen around an exoplanet so small. It may offer clues to how other planets with hydrogen-enveloped atmospheres could have their outer layers evaporated by their parent star, leaving behind solid, rocky ...

Cystic fibrosis is more deadly for Hispanic than non-Hispanic patients, a disparity that is not explained by differences in their access to health care, according to a new study from the Stanford University School of Medicine. The study, published online June 18 in Chest, tracked more than 1,700 California residents with cystic fibrosis. Between 1991 and 2010, Hispanic CF patients were almost three times as likely to die as non-Hispanic CF patients, the study found. The gap in survival existed in spite of the fact that both groups visited CF specialty clinics equally ...

Glowing corals that display a surprising array of colours have been discovered in the deep water reefs of the Red Sea by scientists from the University of Southampton, UK, Tel Aviv University and the Interuniversity Institute for Marine Sciences (IUI), Israel, together with an international team of researchers. The researchers, whose findings have been published online today in research journal PLOS ONE, hope that some of the coral pigments could be developed into new imaging tools for medical applications. The team studied corals at depths of more than 50 metres and ...

Vitamin B12 tweaks how genes behave in the facial bacteria of some people who normally enjoy clear skin. The activity changes of the facial bacteria promote inflammation and lead to pimples. By shedding light on one mechanism behind B12's role in acne, the UCLA finding may identify drug targets that lead to new treatments for acne. Huiying Li, an assistant professor of molecular and medical pharmacology at the David Geffen School of Medicine at UCLA, and Dr. Noah Craft, a dermatologist at LA BioMed at Harbor-UCLA Medical Center, are available for interviews. Science ...

On the hunt for better cancer screening tests, Johns Hopkins scientists led a proof of principle study that successfully identified tumor DNA shed into the blood and saliva of 93 patients with head and neck cancer. A report on the findings is published in the June 24 issue of Science Translational Medicine. "We have shown that tumor DNA in the blood or saliva can successfully be measured for these cancers," says Nishant Agrawal, M.D., associate professor of otolaryngology -- head and neck surgery -- and of oncology at the Johns Hopkins University School of Medicine. "In ...

Various diagnostic imaging techniques are currently used for clinical imaging/disease diagnosis. The accuracy of diagnosis is mainly based on the type of energy used (such as X-ray, sound waves, photons and positrons) to derive the visual information, as well as the degree of spatial resolution (mesoscopic or microscopic) and the level of information that can be obtained (physiological, anatomical or molecular). Based on potential health hazards imposed by type of energy used, clinical imaging modalities can be broadly categorized as ionizing and non-ionizing modalities. ...

From AGU's blogs: Landslide-induced sediment production after the Sabah earthquake in Malaysia The Mw=6.0 5 June 2015 Sabah earthquake in Malaysia, which killed 18 people in rockfalls on Mount Kinabalu, generated landslides that have released large volumes of sediment. The heavy tropical rainfall in Sabah means that this sediment is now starting to enter the river systems in the form of mudflows and sediment-rich flash floods. Dave Petley explores the aftermath of the Sabah earthquake in a new post on The Landslide Blog. From Eos.org: Improving predictions of Arctic ...

A new study of an otherworldly creature from half a billion years ago - a worm-like animal with legs, spikes and a head difficult to distinguish from its tail - has definitively identified its head for the first time, and revealed a previously unknown ring of teeth and a pair of simple eyes. The results, published today in the journal Nature, have helped scientists reconstruct what the common ancestor of everything from tiny roundworms to huge lobsters might have looked like. Researchers from the University of Cambridge, the Royal Ontario Museum and the University of ...

LA JOLLA--Telomeres, specialized ends of our chromosomes that dictate how long cells can continue to duplicate themselves, have long been studied for their links to the aging process and cancer. Now, a discovery at the Salk Institute shows that telomeres may be more central than previously thought to a self-destruct program in cells that prevents tumors, a function that could potentially be exploited to improve cancer therapies. When cells replicate in a process called mitosis, their telomeres get a little shorter each time. Eventually, after many cell divisions, telomeres ...

The prospect of finding ocean-bearing exoplanets has been boosted, thanks to a pioneering new study. An international team of scientists, including from the University of Exeter, has discovered an immense cloud of hydrogen escaping from a Neptune-sized exoplanet. Such a phenomena not only helps explain the formation of hot and rocky 'super-earths', but also may potentially act as a signal for detecting extrasolar oceans. Scientists also believe they can use the discovery to envisage the future of Earth's atmosphere, four billion years from today. The ground-breaking ...

DETROIT - Urban gardens are becoming more commonplace across Detroit and other major urban cities throughout the United States. These gardens offer a source of free or inexpensive healthy food for the public and educate community members about food production and rehabilitating the local ecosystem. The revolution of urban agriculture has the potential to address many economic, environmental and personal health issues. With urban agriculture gaining popularity for improving local and sustainable food systems, the question of food safety has become a growing concern. To ...

The initial results of a study suggested that children born by cesarean section were 21 percent more likely to be diagnosed with autism spectrum disorder but that association did not hold up in further analysis of sibling pairs, implying the initial association was not causal and was more likely due to unknown genetic or environmental factors, according to an article published online by JAMA Psychiatry. Autism spectrum disorder (ASD) is thought to affect about 0.62 percent of children worldwide, although estimates in the United States have been closer to 1.5 percent. ...

The notion that geography often shapes economic and political destiny has long informed the work of economists and political scholars. Now a study led by medical scientists at Johns Hopkins reveals how geography also appears to affect the very survival of people with end-stage kidney disease in need of dialysis. "If you are a person with kidney failure in Texas you're in trouble, but if you're in New England you're golden, and that's profoundly troubling because the quality of care shouldn't be predicated on your ZIP code," says senior investigator Mahmoud Malas, M.D., ...

(BOSTON) - Antibiotics are the mainstay in the treatment of bacterial infections, and together with vaccines, have enabled the near eradication of infectious diseases like tuberculosis, at least in developed countries. However, the overuse of antibiotics has also led to an alarming rise in resistant bacteria that can outsmart antibiotics using different mechanisms. Some pathogenic bacteria are thus becoming almost untreatable, not only in underdeveloped countries but also in modern hospital settings. While some researchers seek to develop antibiotics with new mechanisms ...

COLUMBUS, Ohio - A new study performed by researchers at The Ohio State University Wexner Medical Center shows that when it comes to overuse injuries in high school sports, girls are at a much higher risk than boys. Overuse injuries include stress fractures, tendonitis and joint pain, and occur when athletes are required to perform the same motion repeatedly. The study published in April in the Journal of Pediatrics. Dr. Thomas Best analyzed 3,000 male and female injury cases over a seven year period across 20 high school sports such as soccer, volleyball, gymnastics ...

PITTSBURGH, June 24 -- Moving closer to the possibility of "materials that compute" and wearing your computer on your sleeve, researchers at the University of Pittsburgh Swanson School of Engineering have designed a responsive hybrid material that is fueled by an oscillatory chemical reaction and can perform computations based on changes in the environment or movement, and potentially even respond to human vital signs. The material system is sufficiently small and flexible that it could ultimately be integrated into a fabric or introduced as an inset into a shoe. Anna ...

Researchers from the University of Illinois at Urbana-Champaign have, for the first time, uncovered the complex interdependence and orchestration of metabolic reactions, gene regulation, and environmental cues of clostridial metabolism, providing new insights for advanced biofuel development. "This work advances our fundamental understanding of the complex, system-level process of clostridial acetone-butanol-ethanol (ABE) fermentation," explained Ting Lu, an assistant professor of bioengineering at Illinois. "Simultaneously, it provides a powerful tool for guiding strain ...

Alexandria, VA - Humans depend on copper for everything from electrical wiring to water pipes. To meet demand, the metal has been largely mined from Porphyry Copper Deposits (PCDs). For decades, scientists generally agreed upon the geological processes behind PCD formation; now EARTH Magazine examines two new studies that suggest alternatives to these long-held understandings. From enriched pulses of magmatic fluids creating copper concentrations, to remelted crust allowing deeper PCDs to rise up to shallower depths, these conclusions may better inform geologists about ...

Amsterdam, NL, June 24, 2015 - Despite an urgent need for new medications, clinical trials in Parkinson's disease (PD) have a relatively low rate of success. The reasons for this are complex, prompting a group of investigators from PD advocacy groups to conduct a survey of the principle stakeholders, PD scientists, patients, and caregivers, to determine some of the underlying barriers. Their results are published in the Journal of Parkinson's Disease. "With development of a new drug estimated to cost between $1 and $3 billion and taking as long as 15 years, the successful ...

Cultural "lore" outweighs criminal law when Indigenous drivers in regional and remote communities get behind the wheel drunk, a new study by Queensland University of Technology has found. Michelle Fitts, from QUT's Centre for Accident Research & Road Safety-Queensland (CARRS-Q), said the decision to drink drive was not necessarily made in disregard for criminal law but rather to meet cultural obligations. As part of her Ph.D., Fitts explored the motivations that influence Indigenous people to drink drive in regional and remote communities through one-on-one interviews ...

Researchers from North Carolina State University have developed a new technique for "scheduling" energy in electric grids that moves away from centralized management by tapping into the distributed computing power of energy devices. The approach advances the smart grid concept by coordinating the energy being produced and stored by both conventional and renewable sources. Currently, power infrastructure uses a centralized scheduling approach to forecast and coordinate the energy produced at the thousands of large power plants around the country. But as renewable energy ...

Research has shown that New Zealand blackcurrants are good for keeping us mentally young and agile, a finding that could have potential in managing the mental decline associated with aging populations, or helping people with brain disorders such as Parkinson's disease or depression. The research, conducted by scientists at Plant & Food Research (New Zealand) in collaboration with Northumbria University (UK), showed that compounds found in New Zealand blackcurrants increased mental performance indicators, such as accuracy, attention and mood. The study also showed that ...

Although minority children are frequently reported to be overrepresented in special education classrooms, a team of researchers suggests that minority children are less likely than otherwise similar white children to receive help for disabilities. The previously reported overrepresentation is most likely due to a greater exposure to environmental and economic risk factors, said Paul Morgan, associate professor of education, Penn State. "The general limitation of the available studies is that they haven't been able to correct for minority children's unfortunate, but ...
