| Antioxidants can protect against omega 6 damage -- or promote it Posted: 04 Apr 2014 11:03 AM PDT Given omega 6 fatty acid's reputation for promoting cancer -- at least in animal studies -- researchers are examining the role that antioxidants play in blocking the harmful effects of this culprit, found in many cooking oils. After all, antioxidants are supposed to prevent DNA damage. But employing antioxidants could backfire, say researchers.  |
| Grandparents may worsen some moms' baby blues Posted: 04 Apr 2014 11:03 AM PDT Does living with grandparents ease or worsen a mother's baby blues? The answer may depend on the mother's marital status, a new study suggests. Married and single mothers suffer higher rates of depression when they live in multi-generational households in their baby's first year of life. But for moms who live with, but aren't married to, their partners, it's just the opposite.  |
| Does too much time at the computer lead to lower bone mineral density in adolescents? Posted: 04 Apr 2014 11:02 AM PDT In boys, higher screen time was adversely associated to bone mineral density at all sites even when adjusted for specific lifestyle factors. These were contrasting results to those found in girls -- and this could not be explained by adjustments for the different parameters measured.  |
| Knowledge, use of IUDs increases when women are offered counseling, 'same-day' service Posted: 04 Apr 2014 06:29 AM PDT Health care clinics should routinely offer same-day placement of intrauterine devices (IUDs) to women seeking emergency contraception, according to researchers. The study findings demonstrate that providing patient education along with same-day placement service increases both knowledge and use of IUDs three months and a year after women seek emergency contraception.  |
| Empowering parents to inspire first-generation college-goers Posted: 04 Apr 2014 05:57 AM PDT Parents who have not attended college are at a disadvantage when it comes to talking about higher education with their kids -- yet these are the students who most need a parent's guidance. A new approach developed by researchers may help solve the problem. "There is a common perception that low-income parents don't care about college, but it's not true," said the lead researcher on the project. "The parents we worked with really wanted to be engaged in their kids' educational pursuits -- in fact they came to us and asked us for help."  |
| Impact of long-term vitamin D insufficiency on fracture risk Posted: 04 Apr 2014 05:57 AM PDT The results of a study suggest that long-term low levels of vitamin D intake are associated with higher 10-year fracture risk in elderly women. Vitamin D insufficiency in seniors has been shown to contribute to increased risk of osteoporotic fractures. Previous studies have used single vitamin D measurements to investigate effects on bone. However, in elderly women, relatively little is known about the effects of long-term vitamin D insufficiency on bone health.  |
| Dwindling visibility of tobacco in prime time US TV linked to fall in smoking rates Posted: 03 Apr 2014 06:25 PM PDT The dwindling visibility of tobacco products in prime time US TV drama programs may be linked to a fall in smoking prevalence of up to two packs of cigarettes per adult a year, suggests research. The impact may be as much as half of that exerted by pricing, say the authors.  |
| Posted: 03 Apr 2014 06:24 PM PDT Expensive, intense physiotherapy sessions do not show any additional benefit over a single physiotherapy session of education and advice with phone follow-up, results of a new trial of treatments for chronic whiplash pain suggest. The findings are in line with previous studies on the subject, which have reported minimal additional benefit of longer physiotherapy programs over briefer physiotherapy programs for acute whiplash-associated disorders.  |
| One in 4 people with high blood pressure not taking their meds properly Posted: 02 Apr 2014 06:25 PM PDT Around one in four people prescribed drugs to lower longstanding blood pressure either just doesn't take them at all or only part of the time, suggests a study of a simple technique designed to find out why drug treatment might not be working in these patients. Those referred for further treatment, because of "resistant hypertension" were most likely not to be taking their tablets properly, the findings show.  |
| Men who started smoking before age 11 had fatter sons Posted: 02 Apr 2014 07:57 AM PDT Men who started smoking regularly before the age of 11 had sons who, on average, had 5-10 kg more body fat than their peers by the time they were in their teens, according to new research. The researchers say this could indicate that exposure to tobacco smoke before the start of puberty may lead to metabolic changes in the next generation.  |
| Allergy tablet approval warrants caution for some Posted: 02 Apr 2014 07:55 AM PDT A pill a day keeps spring allergies away. In a perfect world, it would be that easy. And for those suffering from an allergy to some grasses, the Food and Drug Administration's (FDA) approval of the oral dissolvable tablets designed to help treat symptoms may be beneficial. But for the majority of seasonal sufferers allergic to pollens from the more than 30 other pollinating species, relief isn't that easy.  |
| Why we think we're good at something when we're not Posted: 02 Apr 2014 06:50 AM PDT Reality TV shows, like American Idol, are a good example of how we all have a hard time accurately evaluating our abilities. People often think they are good at their job or have a talent, such as singing, because of the feedback they receive from employers, family and friends. Too often that feedback is vague and does not offer any suggestions for improvement. It is much easier to tell someone they are doing a good job instead of being honest and risk hurting their feelings.  |
| Tobacco promotions still reaching youth Posted: 01 Apr 2014 02:30 PM PDT Teens and young adults who are exposed to marketing materials for tobacco products, such as coupons and websites, were far more likely to begin smoking or to be current smokers than those not exposed, finds a new study. The U.S. government has made efforts over time to limit tobacco advertising. For instance, in the 1960s, health concerns about tobacco prompted Congress to ban cigarette ads on television and radio.  |
| Oxytocin, 'love hormone,' promotes group lying, according to researchers Posted: 01 Apr 2014 11:22 AM PDT Oxytocin is a peptide of nine amino acids produced in the brain's hypothalamus, functioning as both a hormone and neurotransmitter. Research has shown that in addition to its bonding effect in couples and between mothers and babies, it also stimulates one's social approach. "Our results suggest people are willing to bend ethical rules to help the people close to us, like our team or family," says the lead researcher. "This raises an interesting, although perhaps more philosophical, question: Are all lies immoral?"  |

| Light-activated neurons from stem cells restore function to paralyzed muscles Posted: 04 Apr 2014 11:03 AM PDT A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists. The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches. These motor neurons are designed to react to pulses of blue light, allowing scientists to fine-tune muscle control by adjusting the intensity, duration and frequency of the light pulses.  |
| Posted: 04 Apr 2014 06:29 AM PDT An international team of researchers has discovered a previously unknown atmospheric phenomenon over the tropical West Pacific. Like in a giant elevator to the stratosphere, many chemical compounds emitted at the ground pass unfiltered through the so-called 'detergent layer' of the atmosphere, known as the 'OH shield.' The newly discovered phenomenon over the South Seas boosts ozone depletion in the polar regions and could have a significant influence on the future climate of the Earth.  |
| Posted: 04 Apr 2014 05:58 AM PDT G2, a doomed gas cloud, is edging closer to Sgr A*, the hungry supermassive black hole at the Milky Way's center. The closest approach between the two is predicted to occur any day now. Astrophysicists have been watching closely, and the data do not show enhanced emission in the X-rays.  |
| Materials, electronics that dissolve when triggered being developed Posted: 04 Apr 2014 05:54 AM PDT An research team is developing "transient materials" and "transient electronics" that can quickly and completely melt away when a trigger is activated. That could mean that one day you could send out a signal to destroy a lost credit card, or when soldiers are wounded, their electronic devices could be remotely triggered to melt away, securing sensitive military information. The field of study is very new, but progress is being made.  |
| Oxytocin, 'love hormone,' promotes group lying, according to researchers Posted: 01 Apr 2014 11:22 AM PDT Oxytocin is a peptide of nine amino acids produced in the brain's hypothalamus, functioning as both a hormone and neurotransmitter.

| Researchers design trees that make it easier to produce paper Posted: 03 Apr 2014 11:20 AM PDT Researchers have genetically engineered trees that will be easier to break down to produce paper and biofuel, a breakthrough that will mean using fewer chemicals, less energy and creating fewer environmental pollutants.  |
| Gravity measurements confirm subsurface ocean on Saturn's moon Enceladus Posted: 03 Apr 2014 11:20 AM PDT In 2005, NASA's Cassini spacecraft sent pictures back to Earth depicting an icy Saturnian moon spewing water vapor and ice from fractures, known as "tiger stripes," in its frozen surface. It was big news that tiny Enceladus -- a mere 500 kilometers in diameter -- was such an active place. Since then, scientists have hypothesized that a large reservoir of water lies beneath that icy surface, possibly fueling the plumes. Now, using gravity measurements collected by Cassini, scientists have confirmed that Enceladus does in fact harbor a large subsurface ocean near its south pole, beneath those tiger stripes.  |
| Fermi data tantalize with new clues to dark matter: Gamma rays from center of Milky Way galaxy Posted: 03 Apr 2014 09:36 AM PDT A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the Harvard-Smithsonian Center for Astrophysics (CfA), the Massachusetts Institute of Technology (MIT) and the University of Chicago have developed new maps showing that the galactic center produces more high-energy gamma rays than can be explained by known sources and that this excess emission is consistent with some forms of dark matter.  |
| Posted: 02 Apr 2014 06:25 PM PDT A surprising new strategy for managing your weight? Bright morning light. People who had most of their daily exposure to bright light in the morning had a significantly lower body mass index (BMI) than those who had most of their light exposure later in the day, reports a new study. The earlier light exposure occurred, the lower the BMI. The influence of morning light on weight was independent of physical activity, caloric intake, sleep timing, age or season.  |
| Ancient volcanic explosions shed light on Mercury's origins Posted: 02 Apr 2014 12:36 PM PDT The surface of Mercury crackled with volcanic explosions for extended periods of the planet's history, according to a new analysis. The findings are surprising considering Mercury wasn't supposed to have explosive volcanism in the first place, and they could have implications for understanding how Mercury formed.  |
| Most comprehensive wiring diagram of the mammalian brain to date Posted: 02 Apr 2014 10:39 AM PDT Researchers have published the first comprehensive, large-scale data set on how the brain of a mammal is wired, providing a groundbreaking data resource and fresh insights into how the nervous system processes information. Their landmark paper describes the publicly available Allen Mouse Brain Connectivity Atlas and demonstrates the exciting knowledge that can be gleaned from this valuable resource.  |
| 'Geologic clock' helps determine moon's age Posted: 02 Apr 2014 10:39 AM PDT Planetary scientists have determined that the moon formed nearly 100 million years after the start of the solar system, according to a new article. This conclusion is based on measurements from the interior of the Earth combined with computer simulations of the protoplanetary disk from which the Earth and other terrestrial planets formed.  |
| Key chocolate ingredients could help prevent obesity, diabetes Posted: 02 Apr 2014 08:00 AM PDT Improved thinking. Decreased appetite. Lowered blood pressure. The potential health benefits of dark chocolate keep piling up, and scientists are now homing in on what ingredients in chocolate might help prevent obesity, as well as type-2 diabetes. They found that one particular type of antioxidant in cocoa prevented laboratory mice from gaining excess weight and lowered their blood sugar levels.  |
| Europeans have three times more Neanderthal genes for lipid catabolism than Asians or Africans Posted: 02 Apr 2014 07:00 AM PDT Contemporary Europeans have as many as three times more Neanderthal variants in genes involved in lipid catabolism than Asians and Africans. Although Neanderthals are extinct, fragments of their genomes persist in modern humans. These shared regions are unevenly distributed across the genome and some regions are particularly enriched with Neanderthal variants.  |
| Biological evidence of positive and negative people in the world Posted: 02 Apr 2014 07:00 AM PDT The ability to stay positive when times get tough -- and, conversely, of being negative -- may be hardwired in the brain, finds new research. The study focused on women because they are twice as likely as men to suffer from anxiety related problems and previously reported sex differences in brain structure and function could have obscured the results.  |
| Natural variation: Warm North Atlantic Ocean promotes extreme winters in U.S. and Europe Posted: 01 Apr 2014 06:04 PM PDT The extreme cold weather observed across Europe and the east coast of the U.S. in recent winters could be partly down to natural, long-term variations in sea surface temperatures, according to a new study. Researchers have shown that a phenomenon known as the Atlantic Multidecadal Oscillation (AMO) -- a natural pattern of variation in North Atlantic sea surface temperatures that switches between a positive and negative phase every 60-70 years -- can affect an atmospheric circulation pattern, known as the North Atlantic Oscillation (NAO), that influences the temperature and precipitation over the Northern Hemisphere in winter.  |
| Ancient stormy weather: World's oldest weather report could revise bronze age chronology Posted: 01 Apr 2014 02:29 PM PDT An inscription on a 3,500-year-old stone block from Egypt may be one of the world's oldest weather reports -- and could provide new evidence about the chronology of events in the ancient Middle East. A new translation of a 40-line inscription on the 6-foot-tall calcite block called the Tempest Stela describes rain, darkness and "the sky being in storm without cessation, louder than the cries of the masses."  |
| Breast milk and diet up to two years old: A means of preventing the risk of child obesity Posted: 01 Apr 2014 08:21 AM PDT Scientists have shown that breast-feeding has a protective effect on the risk of obesity at 20 years of age. Researchers also emphasize that nutritional intake at the age of 2 years are critical in providing this beneficial effect.  |
| Arctic melt season lengthening, ocean rapidly warming Posted: 31 Mar 2014 03:06 PM PDT The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap's thickness, according to a new study.  |
| Posted: 30 Mar 2014 12:16 PM PDT Using a new gene-editing system based on bacterial proteins, researchers have cured mice of a rare liver disorder caused by a single genetic mutation. The findings offer the first evidence that this gene-editing technique, known as CRISPR, can reverse disease symptoms in living animals. CRISPR, which offers an easy way to snip out mutated DNA and replace it with the correct sequence, holds potential for treating many genetic disorders, according to the research team.  |
