A new study offers strategies for rekindling marriage after a spouse returns home from combat with post-traumatic stress symptoms present in one or both of the spouses. For participants as individuals, it's important to allow negative emotions, to give each other time and space to do the work of rediscovery and accept a changed reality, and to recognize and address the individual needs of the other. As couples, strategies include going with the flow, opening your heart, becoming best friends, maintaining trust, and communicating effectively. As families, it's helpful ...

An exciting new special issue of the Canadian Journal of Earth Sciences shines the spotlight on the Danek Bonebed in Edmonton, Alberta and increases our knowledge of Edmonton's urban dinosaurs, especially the iconic hadrosaurid Edmontosaurus. Well-preserved, articulated dinosaur specimens often receive much attention from scientists and the public, but bonebeds provide a great deal of information that even the most spectacular articulated specimens cannot. Because of the amount of fossil material, the quality of preservation, ease of preparation, and volume of associated ...

"Most researchers have treated the order in which the information is shown as a nuisance that can bias the interpretation of data," said Ting Qian, lead author and a former graduate student in brain and cognitive sciences at the University of Rochester. But as Qian's co-author and thesis advisor, Professor Richard Aslin explained, "We see it as a part of the natural statistics of the real world, and therefore a signal--or cue--that can be the basis of rational decisions." In a paper published in the journal Proceedings of the National Academy of Sciences, Qian and Aslin ...

VIDEO: Caltech neuroeconomists have found that your ability to exercise self-control when deciding what to eat may depend upon just how quickly your brain factors healthfulness into a decision. Click here for more information. When you open the refrigerator for a late-night snack, are you more likely to grab a slice of chocolate cake or a bag of carrot sticks? Your ability to exercise self-control--i.e., to settle for the carrots--may depend upon just how quickly your brain factors ...

LANSING, Mich. December 15, 2014 - Cyclists who are preparing for race day may have a new sports drink to give them an edge in recovery: tart cherry juice. A new study published in Applied Physiology, Nutrition, and Metabolism found that Montmorency tart cherry juice helped accelerate recovery, maintain muscle function and reduce certain markers of exercise-induced inflammation among a group of cyclists participating in a simulated road race. The research team, led by Glyn Howatson and Phillip G. Bell at Northumbria University in the U.K., conducted this double-blind, ...

Each day, thunderstorms around the world produce about a thousand quick bursts of gamma rays, some of the highest-energy light naturally found on Earth. By merging records of events seen by NASA's Fermi Gamma-ray Space Telescope with data from ground-based radar and lightning detectors, scientists have completed the most detailed analysis to date of the types of thunderstorms involved. "Remarkably, we have found that any thunderstorm can produce gamma rays, even those that appear to be so weak a meteorologist wouldn't look twice at them," said Themis Chronis, who led ...

Online content creation has become easier than ever and is quickly reaching parity with content consumption. From writing a blog or social media post to letting an app turn your photos into a video montage, anyone with an Internet connection can publish these creations with the click of a button. But in the age of Web publishing, it has become increasingly confusing for content creators to figure out how to protect their original works or to use other content legally -- such as for remixes or parodies -- on major websites for user-generated content, including YouTube ...

New York (15 December 2014)--A study published today is the first detailed assessment of whether the 8-year Iraq War had an effect on childbearing. The study found that before the war, from 1997 to 2003, adolescent fertility in Iraq was stable at just below 70 births per 1,000 girls aged 15-19. However, soon after the beginning of the war, adolescent fertility rose by more than 30 percent, reaching over 95 births per 1,000 girls in 2010. The study is included in the December 2014 issue of Population and Development Review, a peer-reviewed journal published by the Population ...

Tropical Cyclone Bakung ran into adverse conditions in the Southern Indian Ocean that weakened it to a remnant low pressure system when NASA's Aqua satellite spotted it on Dec. 15. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard Aqua captured a visible picture of Bakung's elongated remnants on Dec. 5 at 08:05 UTC (3:05 a.m. EST). The storm appeared to be stretched out from west to east in the visible image. The last advisory on the tropical cyclone came on Dec. 13 when the storm was still a tropical storm with maximum sustained ...

WASHINGTON (Dec. 15, 2014)--Over prescription of antibiotics is a major factor driving one of the biggest public health concerns today: antibiotic resistance. In a first-of-its-kind study, research led by the George Washington University suggests that public health educational materials may not address the misconceptions that shape why patients expect antibiotics, driving doctors to prescribe them more. The research appeared in October in the journal Medical Decision Making. Researchers from George Washington, Cornell and Johns Hopkins universities surveyed 113 patients ...

Researchers in Spain have discovered that if lead atoms are intercalated on a graphene sheet, a powerful magnetic field is generated by the interaction of the electrons' spin with their orbital movement. This property could have implications in spintronics, an emerging technology promoted by the European Union to create advanced computational systems. Graphene is considered the material of the future due to its extraordinary optical and electronic mechanical properties, especially because it conducts electrons very quickly. However, it does not have magnetic properties, ...

To the casual observer, the colonies of social insects like bees and ants appear to be harmonious societies where individuals work together for the common good. But appearances can be deceiving. In fact, individuals within nests compete over crucial determinants of fitness such as reproductive dominance and production of male eggs. The intensity of competition often depends on the level of kinship between colony members. This is because selfish individuals lose indirect fitness when their behavior harms close relatives. A new study by Eva Schultner and colleagues from ...

Just in time for Christmas, Simon Fraser University computing science professor Richard Zhang reveals how to print a 3D Christmas tree efficiently and with zero material waste, using the world's first algorithm for automatically decomposing a 3D object into what are called pyramidal parts. A pyramidal part has a flat base with the remainder of the shape forming upwards over the base with no overhangs, much like a pyramid. A pyramidal shape is optimal for 3D printing because it incurs no material waste and saves print time. The algorithm promises to become a big deal in ...

DALLAS - Dec. 15, 2014 - UT Southwestern Medical Center researchers have identified a possible therapy to treat neurofibromatosis type 1 or NF1, a childhood neurological disease characterized by learning deficits and autism that is caused by inherited mutations in the gene encoding a protein called neurofibromin. Researchers initially determined that loss of neurofibromin in mice affects the development of the part of the brain called the cerebellum, which is responsible for balance, speech, memory, and learning. The research team, led by Dr. Luis F. Parada, Chairman ...

Irvine, Calif., Dec. 15, 2014 - Dangerously high levels of air pollutants are being released in Mecca during the hajj, the annual holy pilgrimage in which millions of Muslims on foot and in vehicles converge on the Saudi Arabian city, according to findings reported today at the American Geophysical Union meeting in San Francisco. "Hajj is like nothing else on the planet. You have 3 to 4 million people - a whole good-sized city - coming into an already existing city," said Isobel Simpson, a UC Irvine research chemist in the Nobel Prize-winning Rowland-Blake atmospheric ...

Early discoveries by NASA's newest Mars orbiter are starting to reveal key features about the loss of the planet's atmosphere to space over time. The findings are among the first returns from NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission, which entered its science phase on Nov. 16. The observations reveal a new process by which the solar wind can penetrate deep into a planetary atmosphere. They include the first comprehensive measurements of the composition of Mars' upper atmosphere and electrically charged ionosphere. The results also offer an unprecedented ...

A breast cancer specialist and clinical researcher at Women & Infants Hospital of Rhode Island presented research yesterday at the 2014 San Antonio Breast Cancer Symposium showing that adding either the chemotherapy drug carboplatin or the blood vessel-targeting drug bevacizumab to the standard treatment of chemotherapy before surgery helped women who have the basal-like subtype of triple-negative breast cancer. "We found that adding either carboplatin or bevacizumab to standard preoperative chemotherapy increased pathologic complete response rates for women with basal-like ...

Noteworthy PNNL research presentations include the following topics: Even with global warming cold air outbreaks will remain Just because the climate is warming doesn't mean Cold Air Outbreaks are going away, especially in Southwestern Canada and Northwestern United States. Overall, global climate models ...

Leading conservation scientists from around the world have called for a substantial role for nuclear power in future energy-generating scenarios in order to mitigate climate change and protect biodiversity. In an open letter to environmentalists with more than 60 signatories, the scientists ask the environmental community to "weigh up the pros and cons of different energy sources using objective evidence and pragmatic trade-offs, rather than simply relying on idealistic perceptions of what is 'green' ". Organized by ecologists Professor Barry Brook and Professor Corey ...

SALT LAKE CITY, Dec. 15, 2014 - The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, University of Utah researchers and their colleagues found. The findings mean the so-called Paleocene-Eocene thermal maximum, or PETM, can provide clues to the future of modern climate change. The good news: Earth and most species survived. The bad news: It took millennia to recover from the episode, when temperatures rose ...

PROVIDENCE, R.I. [Brown University] -- Using a computer algorithm that can sift through mounds of genetic data, researchers from Brown University have identified several networks of genes that, when hit by a mutation, could play a role in the development of multiple types of cancer. The algorithm, called Hotnet2, was used to analyze genetic data from 12 different types of cancer assembled as part of the pan-cancer project of The Cancer Genome Atlas (TCGA). The research looked at somatic mutations -- those that occur in cells during one's lifetime -- and not genetic variants ...

Cold Spring Harbor, NY - The next time you are in a crowded room, or a meeting, or even at the park with your kids, take a look around. How many people are on their phone? Distractions invade every aspect of our lives. Status updates, text messages, email notifications all threaten to steal our attention away from the moment. While we fight the urge to check the phone, our brains are making constant judgment calls about where to focus attention. The brain must continually filter important information from irrelevant interference. Scientists have hypothesized for decades ...

AMHERST, Mass. - Traditional genomic, proteomic and other screening methods currently used to characterize drug mechanisms are time-consuming and require special equipment, but now researchers led by chemist Vincent Rotello at the University of Massachusetts Amherst offer a multi-channel sensor method using gold nanoparticles that can accurately profile various anti-cancer drugs and their mechanisms in minutes. As Rotello and his doctoral graduate student Le Ngoc, one of the lead authors, explain, to discover a new drug for any disease, researchers must screen billions ...

Researchers have released one of the most comprehensive assessments of the timing and amount of greenhouse gas emissions that each of the world's major economies could produce under different scenarios, i.e. without new climate policies, for the currently discussed pledges, and under a scenario that limits future temperature rise to 2°C. "The pledges made so far lead to earlier emission peaking in many countries, with 1-1.5 °C less total warming than without these policies, but not sufficient to meet the 2oC target. Under the proposed commitments, cumulative CO2 ...
