UT Arlington team develops new storage cell for solar energy storage, nighttime conversion

UT Arlington team develops new storage cell for solar energy storage, nighttime conversion
2015-07-01
A University of Texas at Arlington materials science and engineering team has developed a new energy cell that can store large-scale solar energy even when it's dark. The innovation is an advancement over the most common solar energy systems that rely on using sunlight immediately as a power source. Those systems are hindered by not being able to use that solar energy at night or when cloudy conditions exist. The UT Arlington team developed an all-vanadium photo-electrochemical flow cell that allows for efficient and large-scale solar energy storage even at nighttime. ...

Tropical Cyclone Raquel triggers warnings in Solomon Islands

Tropical Cyclone Raquel triggers warnings in Solomon Islands
2015-07-01
NASA's Terra satellite and RapidScat instrument showed a slowly developing Tropical Storm Raquel affecting the Solomon Islands on June 30 and July 1. A tropical cyclone warning was in effect for all provinces of the Solomon Islands on July 1. The RapidScat instrument that flies aboard the International Space Station measures surface winds. When it passed over former Tropical Depression 25P (now Raquel) it gathered data on sustained winds on June 30 from 7:02 to 8:35 UTC (3:02 to 4:35 a.m. EDT). The RapidScat data showed the strongest sustained winds were near 25 meters ...

2015-07-01
A link to the full report can be found here. July 1, 2015 (Washington) - Public attitudes about climate change and energy policy are strongly intertwined with political party affiliation and ideology. But politics play a more modest, or even peripheral, role on public views about other key issues related to biomedical science, food safety and space, according to a new Pew Research Center analysis. The chart below highlights the wide mix of factors tied to public attitudes across a broad set of 22 science issues. It illustrates the strength of connection between political ...

Study details use of antipsychotic medication in young people

2015-07-01
The use of antipsychotic medication increased among adolescents and young adults from 2006 to 2010 but not among children 12 years or younger, according to an article published online by JAMA Psychiatry. Antipsychotics have gained popularity as treatments for psychiatric disorders in young people. Clinical trials support the efficacy of several antipsychotics for child and adolescent bipolar mania, adolescent schizophrenia, and irritability associated with autism in adolescents and children. Yet most office visits by children and adolescents that involve antipsychotic ...

Longer-term follow-up shows greater type 2 diabetes remission for bariatric surgery compared to life

2015-07-01
Among obese participants with type 2 diabetes mellitus, bariatric surgery with 2 years of a low-level lifestyle intervention resulted in more disease remission than did lifestyle intervention alone, according to a study published online by JAMA Surgery. It remains to be established whether bariatric surgery is a durable and effective treatment for type 2 diabetes (T2DM) and how bariatric surgery compares with intensive lifestyle modification and medication management with respect to T2DM-related outcomes. As demonstrated in observational studies and several small randomized ...

Research letter: Indoor tanning rates drop among US adults

2015-07-01
Indoor tanning rates dropped among adults from 5.5 percent in 2010 to 4.2 percent in 2013, although an estimated 7.8 million women and 1.9 million men still engage in the practice, which has been linked to increased cancer risk, according to the results of a study published online in a research letter by JAMA Dermatology. Gery P. Guy Jr., Ph.D., M.P.H., of the Centers for Disease Control and Prevention, Atlanta, and coauthors analyzed data for 59,145 individuals from the 2010 and 2013 National Health Interview Survey, a nationally representative sample of U.S. adults. In ...

Trends in antipsychotic medication use in children, adolescents, and young adults

2015-07-01
New York, NY (July 1, 2015) -- Despite concerns that use of antipsychotic medications in treating young people has increased, use actually declined between 2006 and 2010 for children ages 12 and under, and increased for adolescents and young adults. In a study published today in JAMA Psychiatry, Mark Olfson, MD, MPH, of Columbia University Medical Center (CUMC) and NYS Psychiatric Institute, and his colleagues analyzed prescription data from 2006-2010 to identify trends in the use of antipsychotic medications in young people in the United States. They found that boys ...

Boys more likely to have antipsychotics prescribed, regardless of age

2015-07-01
Boys are more likely than girls to receive a prescription for antipsychotic medication regardless of age, researchers have found. Approximately 1.5 percent of boys ages 10-18 received an antipsychotic prescription in 2010, although the percentage falls by nearly half after age 19. Among antipsychotic users with mental disorder diagnoses, attention deficit hyperactivity disorder (ADHD) was the most common among youth ages 1-18, while depression was the most common diagnosis among young adults ages 19-24 receiving antipsychotics. Despite concerns over the rising use of ...

What makes fireflies glow? (video)

2015-07-01
As fireflies are delighting children across the country with their nighttime displays, scientists are closing in on a better understanding of how the insects produce their enchanting glow. They report in the Journal of the American Chemical Society new evidence of how the beetles' chemistry works. Their findings could apply to the bioluminescence of other organisms, too. About 60 years ago, scientists figured out in broad strokes the cascade of reactions that allows fireflies to produce light. It starts with a chemical called luciferin, which interacts with the energy-transporting ...

What's in your landscape? Plants can alter West Nile virus risk

Whats in your landscape? Plants can alter West Nile virus risk
2015-07-01
CHAMPAIGN, Ill. -- A new study looks at how leaf litter in water influences the abundance of Culex pipiens mosquitoes, which can transmit West Nile virus to humans, domestic animals, birds and other wildlife. The study found that different species of leaf litter in standing water influence where Culex pipiens mosquitoes deposit their eggs, how quickly the larvae grow, how big they get and whether they survive to adulthood. Because the mosquitoes feed on bacteria that grow on leaf litter, the team also measured how native and non-native leaf species influenced bacterial ...

Implantable 'artificial pancreas' could help diabetes patients control their blood sugar

2015-07-01
Living with Type 1 diabetes requires constant monitoring of blood sugar levels and injecting insulin daily. Now scientists are reporting in the ACS journal Industrial & Engineering Chemistry Research the development of an implantable "artificial pancreas" that continuously measures a person's blood sugar, or glucose, level and can automatically release insulin as needed. Type 1 diabetes, previously known as juvenile diabetes, affects about 1.25 million Americans. About 200,000 of them are under 20 years old. The condition arises when a person's own immune system destroys ...

Helping students stick with MOOCs

2015-07-01
MOOCs -- massive open online courses -- grant huge numbers of people access to world-class educational resources, but they also suffer high rates of attrition. To some degree, that's inevitable: Many people who enroll in MOOCs may have no interest in doing homework, but simply plan to listen to video lectures in their spare time. Others, however, may begin courses with the firm intention of completing them but get derailed by life's other demands. Identifying those people before they drop out and providing them with extra help could make their MOOC participation much ...

Producing fuel from Canada oil sands emits more carbon than from US crude

2015-07-01
The production of petroleum from Canada's oil sands is on the rise with much of it destined for U.S. refineries. As the U.S. takes stock of its greenhouse gas emissions, scientists report in the ACS journal Environmental Science & Technology that the current oil sands production of fuels from "well-to-wheels" releases about 20 percent more carbon dioxide into the atmosphere than making gasoline and diesel from conventional crudes. In 2013, the oil industry was producing nearly 2 million barrels per day from Canadian oil sands. By 2030, that number is expected to rise ...

Ultra-stable JILA microscopy technique tracks tiny objects for hours

Ultra-stable JILA microscopy technique tracks tiny objects for hours
2015-07-01
JILA researchers have designed a microscope instrument so stable that it can accurately measure the 3D movement of individual molecules over many hours--hundreds of times longer than the current limit measured in seconds.* The technology was designed to track the machinery of biological cells, down to the tiniest bits of DNA, a single "base pair" of nucleotides among the 3 billion of these chemical units in human genes. But the instrument could be useful well beyond biology, biochemistry and biophysics, perhaps in manufacturing. JILA is a partnership of the National ...

2015-07-01
GRAND RAPIDS, Mich., June 24, 2015 - Researchers at Spectrum Health Helen DeVos Children's Hospital have completed the first clinical trial of a new treatment for children suffering from neuroblastoma. In a clinical trial led by Giselle Sholler, MD, pediatric oncologist at Helen DeVos Children's Hospital and the Neuroblastoma and Medulloblastoma Translational Research Consortium (NMTRC), DFMO, an investigational agent, showed minimal side effects with long-term survival of three patients. This is the first clinical study of an oral dosing form of DFMO in any pediatric population. ...

Should scientists be allowed to genetically alter human embryos?

2015-07-01
Scientists have at their disposal a way to explore the possible prevention of genetic diseases before birth. But should they? Currently, the most promising path forward involves editing the genes of human embryos, a procedure rife with controversy. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, parses the explosive issue. Britt E. Erickson, a senior editor at C&EN, reports that at least one team of scientists has already published a study on altering disease-related genes of human embryos. The experiment was ...

Penn team identifies gene responsible for some cases of male infertility

Penn team identifies gene responsible for some cases of male infertility
2015-07-01
In the most severe form of male infertility, men do not make any measurable levels of sperm. This condition, called azoospermia, affects approximately 1 percent of the male population and is responsible for about a sixth of cases of male infertility. Oftentimes men with azoospermia don't know the underlying cause of their condition. But new research led by University of Pennsylvania scientists suggests that mutations in an X chromosome gene called TEX11 are responsible for a significant number of cases of infertility -- an estimated 1 percent of cases of non-obstructive ...

Emergence of a 'devil's staircase' in a spin-valve system

2015-07-01
Complex magnetic structures are at the heart of promising new materials for devices in "spintronics", a field of research aiming at more energy efficient data storage and processing. A prominent example is the so-called spin valve, where the magnitude of the electrical current passing through a device is very sensitively dependent on its magnetic configuration. These configurations can be readily controlled by a magnetic field in artificial layer systems, resulting in the giant magnetoresistance effect (GMR), a discovery rewarded with the 2007 Noble price in physics to ...

Extreme heat and precipitation are increasing Salmonella infections, UMD study shows
2015-07-01
College Park, Md. -- Extreme heat and precipitation events, which are expected to increase in frequency and intensity due to climate change, are associated with increased risk of Salmonella infections, according to a study led by researchers from the University of Maryland School of Public Health. The study is the first to provide empirical evidence that Salmonella infections related to extreme weather events are disproportionately impacting those living in the coastal areas of Maryland. "We found that extremely hot days and periods of extreme rainfall are contributing ...

Many patients with advanced form of larynx cancer not receiving recommended treatment

2015-07-01
PHILADELPHIA - Despite findings of previous studies and published guidelines, nearly two-thirds of patients with T4a larynx ("voice box") cancer are not receiving a total laryngectomy (surgical removal of the larynx), the recommended form of treatment, and as a result, have significantly worse survival rates versus those treated with a total laryngectomy, a new study published in the International Journal of Radiation Oncology, Biology and Physics by experts at Penn Medicine found. Patients who underwent a laryngectomy, on average, lived nearly two years longer than those ...

The BMJ's data sharing policy now applies to all clinical trials

2015-07-01
From today (1 July 2015) The BMJ requires sharing of individual patient data for all clinical trials. This means that trials will be considered for publication only if the authors agree to make the relevant anonymised patient level data available on reasonable request. The BMJ is the first general medical journal to require data sharing for all trials, extending its initial policy on sharing data for trials of drugs or devices, which took effect in January 2013, says Elizabeth Loder, The BMJ's acting head of research. In an editorial to mark the launch of the new ...

How cortisol reinforces traumatic memories

2015-07-01
The stress hormone cortisol strengthens memories of scary experiences. However, it is effective not only while the memory is being formed for the first time, but also later when people look back at an experience while the memory reconsolidates. This has been published by cognition psychologists from the Ruhr-Universität Bochum in the journal "Neuropsychopharmacology". They suggest that the results might explain the persistence of strong emotional memories occurring in anxiety and Post-Traumatic Stress Disorder (PTSD). Memories of emotional experiences usually fade ...

Liquids on fibers -- slipping or flowing?

2015-07-01
Thin fibers play a tremendous role in many areas of our daily life, from the use of glass fibers in ultra-fast data transmission to textile fibers in our clothing. In order to enable special properties of these fibers, they are often coated with a thin liquid layer that is supposed to be stable and homogeneous. However, for the production of drinkable water, the exact opposite features are desired: there, one aims at harvesting water, which is transported along the fiber as a liquid film or as liquid droplets, from fog. Now, scientists have been able to reveal, by means ...

Observing the birth of a planet

2015-07-01
This news release is available in German. Observing time at the European Southern Observatory (ESO) on Paranal Mountain is a very precious commodity - and yet the Very Large Telescope (VLT) in Chile spent an entire night with a high-resolution infrared camera pointed at a single object in the night sky. The data collected by the Naco optics instrument enabled an international team headed by ETH Zurich's Sascha Quanz to confirm its earlier hypothesis: that a young gas planet - presumed not unlike Jupiter in our own solar system - is orbiting the star designated HD 100546. At ...
