WASHINGTON – Deep down, men may not bask in the glory of their successful wives or girlfriends. While this is not true of women, men's subconscious self-esteem may be bruised when their spouse or girlfriend excels, says a study published by the American Psychological Association. It didn't matter if their significant other was an excellent hostess or intelligent, men were more likely to feel subconsciously worse about themselves when their female partner succeeded than when she failed, according to the study published online in the APA Journal of Personality and Social ...

Scientists at ETH Zurich and the Lawrence Livermore National Laboratory (LLNL) in California have developed an innovative sensor for surface-enhanced Raman spectroscopy (SERS). Thanks to its unique surface properties at nanoscale, the method can be used to perform analyses that are more reliable, sensitive and cost-effective. In experiments with the new sensor, the researchers were able to detect a certain organic species (1,2bis(4-pyridyl)ethylene, or BPE) in a concentration of a few hundred femtomoles per litre. A 100 femtomolar solution contains around 60 million molecules ...

All too often, when a person takes a pill full of a potent and effective drug, the drug passes straight through the body, not reaching the organ where it is needed — a waste of money and inconvenient if it is a cold medicine, but potentially dire if it is a treatment for a serious illness. Polymer chemists at Virginia Tech and pharmaceutical scientists at Purdue University have teamed up to design a solution. Their research to identify, understand, and create new polymer additives that enhance the ability of orally administered drugs to reach the bloodstream has been ...

Even though most Americans believe some kind of conspiracy theory about HIV care and research, many are willing to take part in vaccine trails, according to a new study1 by Ryan Westergaard of the University of Wisconsin School of Medicine and Public Health, published in Springer's Journal of General Internal Medicine.2 The study found no link between distrust in medical research and willingness to participate in related studies. Westergaard and his team asked 601 Chicago residents at various shopping centers to voluntarily complete a set of 235 questions. The survey ...

Chicago, IL – (August 27, 2013) – When a woman becomes pregnant, she knows it is important to maintain a healthy lifestyle to ensure both the health of herself and the health of her baby. New clinical recommendations from the American Academy of Periodontology (AAP) and the Eurpean Federation of Periodontology (EFP) urge pregnant women to maintain periodontal health as well. Research has indicated that women with periodontal disease may be at risk of adverse pregnancy outcomes, such giving birth to a pre-term or low-birth weight baby, reports the AAP and EFP. Periodontal ...

Tuesday, August 27: The radioactive ocean plume from the 2011 Fukushima nuclear plant disaster will reach the shores of the US within three years from the date of the incident but is likely to be harmless according to new paper in the journal Deep-Sea Research 1. While atmospheric radiation was detected on the US west coast within days of the incident, the radioactive particles in the ocean plume take considerably longer to travel the same distance. In the paper, researchers from the Centre of Excellence for Climate System Science and others used a range of ocean simulations ...

SAN DIEGO, Calif. (August 28, 2013) — In the United States there are millions of sports related concussions each year, but many go undiagnosed because for some athletes, the fear of being benched trumps the fear of permanent brain damage, and there is no objective test available to accurately diagnose concussions on the sidelines. Researchers at San Diego State University have set out to change that. A team led by Daniel Goble, an exercise and nutritional sciences professor at SDSU, have developed software and an inexpensive balance board that can measure balance with ...

Researchers have identified five enzymes that are essential to the survival of a parasitic worm that infects livestock worldwide and is a great threat to global food security. Two of these proteins are already being studied as potential drug targets against other pathogens. The team sequenced the genome of Haemonchus contortus, or the barber pole worm, a well-studied parasitic worm that resides in the gut of sheep and other livestock globally. This genome could provide a comprehensive understanding of how treatments against parasitic worms work and point to further new ...

Much as human siblings can have vastly different personalities despite their similar resemblance and genetics, two closely related species of electric fish from the Amazon produce very different electric signals. These species, new to science, are described in the open access journal ZooKeys by Drs. John Sullivan of Cornell University in Ithaca, New York, Jansen Zuanon of the National Amazonian Research Institute in Manaus, Brazil and Cristina Cox Fernandes of the University of Massachusetts, Amherst. The two new species are bluntnose knifefish, genus Brachyhypopomus, ...

Patients attending clinical nurse specialist clinics do not get inferior treatment to that offered by consultant rheumatologists, the results of a major new clinical trial have revealed. The results of the multi-centre trial at the University of Leeds, funded by Arthritis Research UK, showed that there may be some clinical benefit to people with rheumatoid arthritis, whose condition is managed in clinics run by rheumatology clinical nurse specialists, especially with respect to their disease activity, pain control, physical function and general satisfaction with their ...

An innovative measurement method was used at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw for estimating power generated by motors of single molecule in size, comprising a few dozens of atoms only. The findings of the study are of crucial importance for construction of future nanometer machines – and they do not instil optimism. Nanomachines are devices of the future. Composed of a very little number of atoms, they would be in the range of billionth parts of a meter in size. Construction of efficient nanomachines would lead most likely ...

New research suggests that children are far less likely to be diagnosed with Attention deficit hyperactivity disorder (ADHD) in the UK than they are in the USA. However, the same study, led by the University of Exeter Medical School, suggests that autism diagnosis is still rising. The study is published online in the Journal of Autism Developmental Disorders, published by Springer, and was supported by the NIHR Collaboration for Leadership in Applied Health Research and Care in the South West Peninsula (NIHR PenCLAHRC). ADHD is thought to be the most common disorder of ...

The first mammals arose in the Triassic period, over 225 million years ago. These early furballs include small shrew-like animals such as Morganucodon from England, Megazostrodon from South Africa, and Bienotherium from China. They had differentiated teeth (incisors, canines, molars) and large brains and were probably warm-blooded and covered in fur – all characteristics that make them stand apart from their reptile ancestors, and which contribute to their huge success today. However, new research from the University of Lincoln, the National Museum in Bloemfontein, ...

Leveraging the amazing natural properties of the Morpho butterfly's wings, scientists have developed a nanobiocomposite material that shows promise for wearable electronic devices, highly sensitive light sensors and sustainable batteries. A report on the new hybrid material appears in the journal ACS Nano. Eijiro Miyako and colleagues explain that Morpho butterfly wings have natural properties that are beyond the capabilities of any current technology to reproduce artificially. In addition to being lightweight, thin and flexible, the butterfly's wings absorb solar energy, ...

Astronomers have only been observing the Sun with telescopes for 400 years — a tiny fraction of the Sun's age of 4.6 billion years. It is very hard to study the history and future evolution of our star, but we can do this by hunting for rare stars that are almost exactly like our own, but at different stages of their lives. Now astronomers have identified a star that is essentially an identical twin to our Sun, but 4 billion years older — almost like seeing a real version of the twin paradox in action [1]. Jorge Melendez (Universidade de São Paulo, Brazil), the leader ...

A modified law of gravity correctly predicted, in advance of the observations, the velocity dispersion -- the average speed of stars within a galaxy relative to each other -- in 10 dwarf satellite galaxies of the Milky Way's giant neighbor Andromeda. The relatively large velocity dispersions observed in these types of dwarf galaxies is usually attributed to dark matter. Yet predictions made using the alternative hypothesis Modified Newtonian Dynamics (MOND) succeeded in anticipating the observations. Stacy McGaugh, professor of astronomy at Case Western Reserve, and ...

In the midst of an intensifying global water crisis, scientists are reporting development of a more economical way to use one form of the "ice that burns" to turn very salty wastewater from fracking and other oil and gas production methods into water for drinking and irrigation. The study on the method, which removes more than 90 percent of the salt, appears in the journal ACS Sustainable Chemistry & Engineering. Yongkoo Seol and Jong-Ho Cha explain that salty wastewater is a byproduct of oil and gas production, including hydraulic fracturing, or fracking. These methods ...

In the latest advance in efforts to find an inexpensive way to make hydrogen from ordinary water — one of the keys to the much-discussed "hydrogen economy" — scientists are reporting that powder from high-grade charcoal and other forms of carbon can free hydrogen from water illuminated with laser pulses. A report on the discovery appears in ACS' Journal of Physical Chemistry C. Ikuko Akimoto and colleagues point out that traditional approaches to breaking down water, which consists of hydrogen and oxygen, involve use of expensive catalysts or electric current passed through ...

For online and print audiences deep into lazy late-summer-day reading, yearning for diversions from everyday cares, how about a glimpse 400 years back in time at a famous clash between Galileo and an arch-enemy over why ice floats on water? That debate, between a giant in the history of science and a little-remembered naysayer who challenged Galileo's idea that Earth revolves around the sun, is the topic of a story in the current edition of Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society. Sarah ...

Four alcohol brands—Patron tequila, Hennessy cognac, Grey Goose vodka, and Jack Daniel's whiskey—accounted for more than half of alcohol brand mentions in the songs that mentioned alcohol use in Billboard's most popular song lists in 2009, 2010 and 2011, according to a new study from researchers at the Boston University School of Public Health and the Center on Alcohol Marketing and Youth (CAMY) at the Johns Hopkins Bloomberg School of Public Health. The study, published online by Substance Use & Misuse and the first to examine the context of specific brand mentions in ...

The Los Angeles Times reports: "The Rim fire spread deeper into Yosemite National Park on Tuesday with flames racing unimpeded to the east even as firefighters shored up defenses for communities on the western edges of the blaze. The fire was 20% contained by Tuesday evening, with almost all of the containment coming on the fire's southwest edge. On the east, the fire has a relatively flat, clear path farther into Yosemite and the 3,700 firefighters battling the blaze have fewer options to control it. The blaze has destroyed 111 buildings, including 31 residences, and ...

NASA's Tropical Rainfall Measuring Mission satellite, also known as TRMM has the ability to measure rainfall from space. When Tropical Storm Fernand formed near Mexico's Gulf coast earlier this week, TRMM gathered data on the storm. Heavy rain with Tropical Storm Fernand generated mudslides. According to the Latin Times, a total of 13 people died as the result of mudslides from Fernand's heavy rainfall. Nine people died in the municipality of Yecuautla, while three people died in Tuxpan and one person in Atzalan. TRMM precipitation data are used to calibrate rainfall ...

The patient-relevant benefit of positron emission tomography (PET) in oesophageal cancer, alone or in combination with computed tomography (CT), is not proven due to a lack of comparative studies. In terms of their diagnostic and prognostic accuracy, it also remains unclear whether these diagnostic techniques can detect the spreading of tumours better than conventional diagnostics. This is the conclusion of the final report of the German Institute for Quality and Efficiency in Health Care (IQWiG) published on 20 August 2013. More reliable diagnosis ought to improve treatment About ...

Baltimore, MD – August 28, 2013 – A research team at the University of Maryland School of Medicine has identified a cell signaling pathway which plays a significant role in causing developmental defects of the fetal spinal cord and brain in babies of women with diabetes. Using an animal model of disease, the team's results point to a potential new therapeutic target for preventing these defects in pregnant women having preexisting diabetes. The results of this study are published in the August 27th issue of Science Signaling. "Providing the best possible care for women ...
