| Impact of childhood bullying still evident after 40 years Posted: 17 Apr 2014 06:25 PM PDT The negative social, physical and mental health effects of childhood bullying are still evident nearly 40 years later, according to new research. The study is the first to look at the effects of bullying beyond early adulthood. Just over a quarter of children in the study (28%) had been bullied occasionally, and 15% bullied frequently -- similar to rates in the UK today. Individuals who were bullied in childhood were more likely to have poorer physical and psychological health and cognitive functioning at age 50. Individuals who were frequently bullied in childhood were at an increased risk of depression, anxiety disorders, and suicidal thoughts.  |
| Gene variant increases risk of colorectal cancer from eating processed meat Posted: 17 Apr 2014 04:16 PM PDT A common genetic variant that affects one in three people appears to significantly increase the risk of colorectal cancer from the consumption of processed meat, according to a new study.  |
| Inhibited children become anxious adults: Examining the causes and effects of early shyness Posted: 17 Apr 2014 12:59 PM PDT Three little girls sit together in a room, playing with the toys surrounding them. One of the girls -- "Emma" -- has clearly taken charge of the group, and the others happily go along with her. A fourth girl -- "Jane" -- enters the room, hiding her face while clinging to her mother. The first three continue to play, while mom sits Jane down with some toys a few feet away from the group. After mom leaves, however, Jane sits alone against the wall. Emma makes her way over to Jane, inviting her to play with the rest of the group. Jane -- looking trapped -- starts to cry, then stands up and tries desperately to open the door.  |
| Loud talking, horseplay in car results in more serious incidents for teen drivers Posted: 17 Apr 2014 11:19 AM PDT Adolescent drivers are often distracted by technology while they are driving, but loud conversations and horseplay between passengers appear more likely to result in a dangerous incident, according to a new study. Researchers ecruited 52 North Carolina high-school age drivers to have in-vehicle cameras mounted in their cars and trucks to observe distracted driving behaviors and distracted conditions when teen drivers were behind the wheel. Young drivers were recorded in a variety of real-world driving situations over six months -- with parents in the car, with other teens in the car and alone.  |
| Fish consumption advisories for expecting mothers fail to cover all types of contaminants Posted: 17 Apr 2014 11:19 AM PDT Fish consumption advisories for expecting mothers are ineffective in reducing infant exposure to contaminants like persistent organic pollutants. The researchers' model estimates that women who stop eating fish shortly before or during their pregnancy may only lower their child's exposure to POPs by 10 to 15 per cent.  |
| Connecting sleep deficits among young fruit flies to disruption in mating later in life Posted: 17 Apr 2014 11:19 AM PDT Mom always said you need your sleep, and it turns out, she was right. According to a new study, the lack of sleep in young fruit flies profoundly diminishes their ability to do one thing they do really, really well -- make more flies. To address whether sleep loss in young flies affects development of courtship circuits, the team investigated a group of neurons implicated in courtship. One particular subset of those neurons was smaller in sleep-deprived animals than normal flies, suggesting a possible mechanism for how sleep deprivation can lead to altered courting behavior.  |
| Boosting depression-causing mechanisms in brain increases resilience, surprisingly Posted: 17 Apr 2014 11:18 AM PDT New research uncovers a conceptually novel approach to treating depression. Instead of dampening neuron firing found with stress-induced depression, researchers demonstrated for the first time that further activating these neurons opens a new avenue to mimic and promote natural resilience.  |
| Internet use may cut retirees' depression Posted: 17 Apr 2014 09:47 AM PDT Spending time online has the potential to ward off depression among retirees, particularly among those who live alone, according to research. Authors report that internet use reduced the probability of a depressed state by 33 percent among their study sample. Late-life depression affects between 5 and 10 million Americans age 50 and older. This new study shows that the Internet offers older Americans a chance to overcome the social and spatial boundaries that are believed to fuel depression.  |
| Distracted driving among teens threatens public health and safety Posted: 17 Apr 2014 06:05 AM PDT Motor vehicle crashes rank as the leading cause of teen deaths and in 2008, 16% of all distraction-related fatal automobile crashes involved drivers under 20 years of age. These grim statistics, coupled with an increasing nationwide awareness of the dangers of distracted driving for all ages, prompted the publication of important research that explores the causes of distracted driving and offers practical recommendations to reduce the incidence of distracted driving among teens.  |
| Book early, after work if you want to enjoy your next hotel stay Posted: 16 Apr 2014 01:24 PM PDT If you're planning a summer vacation or weekend getaway, when you book your hotel room can make a big difference. A new study found you'll be happier with your hotel stay if you book your room after business hours. The research found that consumers who made reservations during business hours selected a higher quality hotel, but they were ultimately less satisfied with their choice. Additionally, the study's findings on hotel quality and satisfaction is the same regardless of whether a reservation is made online, by phone or through a travel agent.  |
| In old age, lack of emotion, interest may signal brain is shrinking Posted: 16 Apr 2014 01:24 PM PDT Older people who have apathy but not depression may have smaller brain volumes than those without apathy, according to a new study. Apathy is a lack of interest or emotion.  |
| Massage therapy improves circulation, alleviates muscle soreness Posted: 16 Apr 2014 09:54 AM PDT Massage therapy improves general blood flow and alleviates muscle soreness after exercise, according to a study. The results also showed that massage improved vascular function in people who had not exercised, suggesting that massage has benefits for people regardless of their level of physical activity.  |
| Low vitamin D may not be a culprit in menopause symptoms Posted: 16 Apr 2014 06:08 AM PDT No significant connection between vitamin D levels and menopause symptoms has been made from the results of a research project on the topic. The authors analyzed the relationship between the blood levels of vitamin D and a number of menopause symptoms, including hot flashes, night sweats, sleep disturbance, concentration, and forgetfulness in 530 women who participated in the calcium and vitamin D trial.  |

| First potentially habitable Earth-sized planet confirmed by Gemini and Keck observatories Posted: 17 Apr 2014 11:19 AM PDT The first Earth-sized exoplanet orbiting within the habitable zone of another star has been confirmed by observations with both the W. M. Keck Observatory and the Gemini Observatory. The initial discovery, made by NASA's Kepler Space Telescope, is one of a handful of smaller planets found by Kepler and verified using large ground-based telescopes. It also confirms that Earth-sized planets do exist in the habitable zone of other stars.  |
| Posted: 17 Apr 2014 11:18 AM PDT Scientists were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice. This finding provides strong evidence that the ice sheet has persisted much longer than previously known, enduring through many past periods of global warming.  |
| Posted: 16 Apr 2014 02:22 PM PDT New research demonstrates how carnivores transitioned into herbivores for the first time on land. Previously unknown, the 300-million-year old fossilized juvenile skeleton of Eocasea martini is less than 20 cm long. Found in Kansas, it consists of a partial skull, most of the vertebral column, the pelvis and a hind limb. By comparing the skeletal anatomy of related animals, scientists discovered that Eocasea martini belonged to the caseid branch of the group Synapsid. This group, which includes early terrestrial herbivores and large top predators, ultimately evolved into modern living mammals. Eocasea lived nearly 80 million years before the age of dinosaurs.  |
| Eavesdropping on brain cell chatter Posted: 16 Apr 2014 11:33 AM PDT Everything we do -- all of our movements, thoughts and feelings -- are the result of neurons talking with one another, and recent studies have suggested that some of the conversations might not be all that private. Brain cells known as astrocytes may be listening in on, or even participating in, some of those discussions. But a new mouse study suggests that astrocytes might only be tuning in part of the time -- specifically, when the neurons get really excited about something.  |
| How smells stick to your memories: Your nose can be a pathfinder Posted: 16 Apr 2014 10:33 AM PDT Waves in your brain make smells stick to your memories and inner maps. Researchers have recently discovered the process behind this phenomenon. The brain, it turns out, connects smells to memories through an associative process where neural networks are linked through synchronized brain waves of 20-40 Hz.  |
| Posted: 16 Apr 2014 10:33 AM PDT It does not always take a huge accelerator to do particle physics: First results from a low energy, table top alternative takes validity of Newtonian gravity down by five orders of magnitude and narrows the potential properties of the forces and particles that may exist beyond it by more than one hundred thousand times. Gravity resonance spectroscopy is so sensitive that it can now be used to search for Dark Matter and Dark Energy.  |
| Scientists re-define what's healthy in newest analysis for human microbiome project Posted: 16 Apr 2014 10:31 AM PDT A new look at the Human Microbiome Project shows wide variation in the types of bacteria found in healthy people. Based on their findings, there is no single healthy microbiome. Rather each person harbors a unique and varied collection of bacteria that's the result of life history as well their interactions with the environment, diet and medication use.  |
| Posted: 15 Apr 2014 05:37 PM PDT A functional brain imaging technique known as positron emission tomography is a promising tool for determining which severely brain damaged individuals in vegetative states have the potential to recover consciousness, according to new research.  |
| Real-time audio of corporal punishment shows kids misbehave within 10 minutes of spanking Posted: 15 Apr 2014 11:40 AM PDT Real-time audio recordings of children being spanked showed parents responded impulsively or emotionally, rather than being intentional with their discipline, says a psychologist and parenting expert. Researchers discovered that spanking was more common than parents admit, that children were hit for trivial misdeeds, and that children misbehaved within 10 minutes of punishment.  |
| New method of screening children for autism spectrum disorders works at 9 months old Posted: 15 Apr 2014 09:55 AM PDT Researchers have identified head circumference and head tilting reflex as two reliable biomarkers in the identification of autism spectrum disorders (ASD) in children that are between 9 and 12 months of age. ASD is identifiable as early as two years old, although most children are not identified until after the age of four. While a number of studies have reported that parents of children with ASD notice developmental problems in children before their first birthday, there has yet to be a screening tool to identify those children.  |
| How nerve cells flexibly adapt to acoustic signals Posted: 11 Apr 2014 07:31 AM PDT Nerve cells flexibly adapt to acoustic signals, research has shown. Depending on the input signal, neurons generate action potentials either near or far away from the cell body. Nerve cells ensure that the various kinds of input signals are optimally processed -- and thus allow us to perceive both small and large acoustic arrival time differences well, and thereby localize sounds in space.  |
| Impact of the 1,000 mph supersonic car predicted Posted: 11 Apr 2014 07:31 AM PDT What are the aerodynamic characteristics of traveling at 1,000 mph? Simulations have looked at how the car will cope with the supersonic rolling ground, rotating wheels and resulting shock waves in close proximity to the test surface at the record attempt site in Hakskeen Pan, South Africa. Where, in 2015, it will make high speed test runs of up to 800mph, with the full 1,000mph attempt scheduled for 2016.  |
| Grandmas stay sharp when they care for grandkids once a week Posted: 08 Apr 2014 08:17 AM PDT Taking care of grandkids one day a week helps keep grandmothers mentally sharp, finds a study. That's good news for women after menopause, when women need to lower their risks of developing Alzheimer's disease and other cognitive disorders. On the other hand, taking care of grandchildren five days a week or more had some negative effects on tests of mental sharpness.  |

| ADHD: Scientists discover brain's anti-distraction system Posted: 18 Apr 2014 11:12 AM PDT Psychologists have made a brain-related discovery that could revolutionize doctors' perception and treatment of attention-deficit disorders. This discovery opens up the possibility that environmental and/or genetic factors may hinder or suppress a specific brain activity that the researchers have identified as helping us prevent distraction.  |
| Mom's diet mirrors child's food allergies Posted: 18 Apr 2014 11:08 AM PDT A long-term study evaluating maternal diet's impact on food allergy in later life is expected to uncover causes of allergy in children. A particular focus for the project is the different effects of allergenic foods in different contexts.  |
| Impact of childhood bullying still evident after 40 years Posted: 17 Apr 2014 06:25 PM PDT The negative social, physical and mental health effects of childhood bullying are still evident nearly 40 years later, according to new research. The study is the first to look at the effects of bullying beyond early adulthood. Just over a quarter of children in the study (28%) had been bullied occasionally, and 15% bullied frequently -- similar to rates in the UK today. Individuals who were bullied in childhood were more likely to have poorer physical and psychological health and cognitive functioning at age 50. Individuals who were frequently bullied in childhood were at an increased risk of depression, anxiety disorders, and suicidal thoughts.  |
| Recalculating costs of combination vaccines Posted: 17 Apr 2014 04:20 PM PDT One of the most popular vaccine brands for children may not be the most cost-effective choice. And doctors may be overlooking some cost factors when choosing vaccines, driving the market toward what is actually a more expensive option, according to a new study. The researchers encourage physicians and advisory boards to take all factors into account when determining how to administer the best combination of vaccines for the lowest cost.  |
| Multitarget TB drug could treat other diseases, evade resistance Posted: 17 Apr 2014 04:20 PM PDT A drug under clinical trials to treat tuberculosis could be the basis for a class of broad-spectrum drugs that act against various bacteria, fungal infections and parasites, yet evade resistance, according to a study. The team determined the different ways the drug SQ109 attacks the tuberculosis bacterium, how the drug can be tweaked to target other pathogens from yeast to malaria -- and how targeting multiple pathways reduces the probability of pathogens becoming resistant.  |
| Target for treating dengue fever discovered Posted: 17 Apr 2014 04:17 PM PDT New research may help scientists develop treatments or vaccines for dengue fever, West Nile virus, yellow fever, Japanese encephalitis and other disease-causing flaviviruses. More than 40 percent of people around the world are at risk of being bitten by mosquitoes infected with the virus that causes Dengue fever and more than 100 million people are infected. This new work explains how flaviviruses produce a unique RNA molecule that leads to disease.  |
| How the immune system protects children from malaria Posted: 17 Apr 2014 04:17 PM PDT Children who live in regions of the world where malaria is common can mount an immune response to infection with malaria parasites that may enable them to avoid repeated bouts of high fever and illness and partially control the growth of malaria parasites in their bloodstream. The findings may help researchers develop future interventions that prevent or mitigate the disease caused by the malaria parasite.  |
| Malaria pathogen's cellular skeleton under super-microscope Posted: 17 Apr 2014 04:17 PM PDT The tropical disease malaria is caused by the Plasmodium parasite. For its survival and propagation, Plasmodium requires a protein called actin. Scientists used high-resolution structural biology methods to investigate the different versions of this protein in the parasite. Their results may in the future contribute to the development of tailor-made drugs against malaria -- a disease that causes more than half a million deaths per year.  |
| Gene variant raises risk for aortic tear, rupture Posted: 17 Apr 2014 04:17 PM PDT The significance of a genetic variant that substantially increases the risk of a frequently fatal thoracic aortic dissection or full rupture has been confirmed by researchers. Thoracic aortic aneurysms, or bulges in the artery wall, can develop without pain or other symptoms. If they lead to a tear -- dissection -- or full rupture, the patient will often die without immediate treatment. Therefore, better identification of patients at risk for aortic aneurysm and dissection is considered essential.  |
| Novel stapled peptide nanoparticle combination prevents RSV infection, study finds Posted: 17 Apr 2014 04:17 PM PDT A combination of advanced technologies may lead to a therapy to prevent or treat respiratory syncytial virus, a potentially lethal respiratory infection affecting infants, young children and the elderly, new research suggests. Despite a wide range of anti-RSV efforts, there are no vaccines or drugs on the market to effectively prevent or treat the infection.  |
| Tracking flu levels with Wikipedia Posted: 17 Apr 2014 04:16 PM PDT Can monitoring Wikipedia hits show how many people have the flu? Researchers have developed a method of estimating levels of influenza-like illness in the American population by analyzing Internet traffic on specific flu-related Wikipedia articles.  |
| Our brains are hardwired for language Posted: 17 Apr 2014 04:16 PM PDT People blog, they don't lbog, and they schmooze, not mshooze. But why is this? Why are human languages so constrained? Can such restrictions unveil the basis of the uniquely human capacity for language? New research shows the brains of individual speakers are sensitive to language universals. Syllables that are frequent across languages are recognized more readily than infrequent syllables. Simply put, this study shows that language universals are hardwired in the human brain.  |
| Deadly human pathogen Cryptococcus fully sequenced Posted: 17 Apr 2014 04:16 PM PDT A ten-year effort by an international team has sequenced the entire genome and all the RNA products of the most important pathogenic lineage of Cryptococcus neoformans, a strain called H99.These genetic instructions can give valuable insight into why a fungus responsible for a million cases of pneumonia and meningitis every year is so malleable and dangerous.  |
| Proteomics discovers link between muscle damage and cerebral malaria Posted: 17 Apr 2014 04:16 PM PDT Malaria-related complications remain a major cause of death for children in many parts of the world. Why some children develop these complications while others don't is still not understood. Scientists now report results of a systematic proteomics approach to the question.  |
| Gene variant increases risk of colorectal cancer from eating processed meat Posted: 17 Apr 2014 04:16 PM PDT A common genetic variant that affects one in three people appears to significantly increase the risk of colorectal cancer from the consumption of processed meat, according to a new study.  |
| Building 'smart' cell-based therapies Posted: 17 Apr 2014 01:42 PM PDT A technology for engineering human cells as therapies has been developed by scientists. The the technology becomes activated only in diseased tissues. It sits on the surface of a cell and can be programmed to sense specific external factors. For example, the engineered cell could detect big, soluble protein molecules that indicate that it's next to a tumor. When the biosensor detects such a factor, it sends a signal into the engineered cell's nucleus to activate a gene expression program, such as the production of tumor-killing proteins or chemicals.  |
| Inhibited children become anxious adults: Examining the causes and effects of early shyness Posted: 17 Apr 2014 12:59 PM PDT Three little girls sit together in a room, playing with the toys surrounding them. One of the girls -- "Emma" -- has clearly taken charge of the group, and the others happily go along with her. A fourth girl -- "Jane" -- enters the room, hiding her face while clinging to her mother. The first three continue to play, while mom sits Jane down with some toys a few feet away from the group. After mom leaves, however, Jane sits alone against the wall. Emma makes her way over to Jane, inviting her to play with the rest of the group. Jane -- looking trapped -- starts to cry, then stands up and tries desperately to open the door.  |
| Is Parkinson's an autoimmune disease? Posted: 17 Apr 2014 12:12 PM PDT The cause of neuronal death in Parkinson's disease is still unknown, but a new study proposes that neurons may be mistaken for foreign invaders and killed by the person's own immune system, similar to the way autoimmune diseases like type 1 diabetes, celiac disease, and multiple sclerosis attack the body's cells.  |
| Loud talking, horseplay in car results in more serious incidents for teen drivers Posted: 17 Apr 2014 11:19 AM PDT Adolescent drivers are often distracted by technology while they are driving, but loud conversations and horseplay between passengers appear more likely to result in a dangerous incident, according to a new study. Researchers ecruited 52 North Carolina high-school age drivers to have in-vehicle cameras mounted in their cars and trucks to observe distracted driving behaviors and distracted conditions when teen drivers were behind the wheel. Young drivers were recorded in a variety of real-world driving situations over six months -- with parents in the car, with other teens in the car and alone.  |
| How vision makes sure that little fish do not get carried away Posted: 17 Apr 2014 09:47 AM PDT Our eyes not only enable us to recognize objects, they also provide us with a continuous stream of information about our own movements. The world glides by us and leaves a characteristic motion trace on our retinas. Seemingly without effort, our brain calculates self-motion from this "optic flow." This way, we can maintain a stable position and a steady gaze during our own movements. Scientists have now discovered an array of new types of neurons, which help the brain of zebrafish to perceive, and compensate for, self-motion.  |
| Adrenaline does little to increase patient's survival after cardiac arrest, study finds Posted: 17 Apr 2014 09:45 AM PDT Giving patients adrenaline after they suffer a cardiac arrest outside of a hospital does not increase their prospects of surviving long-term, according to new research. When a person has a cardiac arrest, his or her heart stops beating. Unless the heart is restarted within minutes, the person usually dies. More than 90 per cent of people who experience a cardiac arrest outside of a hospital will die before reaching a hospital or soon after.  |
| Refining language for chromosomes Posted: 17 Apr 2014 09:44 AM PDT A new classification system that may standardize how structural chromosomal rearrangements are described has been proposed by a team of researchers. Known as Next-Gen Cytogenetic Nomenclature, it is a major contribution to the classification system to potentially revolutionize how cytogeneticists worldwide translate and communicate chromosomal abnormalities.  |
| Neurons in brain tune into different frequencies for different spatial memory tasks Posted: 17 Apr 2014 09:43 AM PDT Your brain transmits information about your current location and memories of past locations over the same neural pathways using different frequencies of a rhythmic electrical activity called gamma waves, report neuroscientists. The research may provide insight into the cognitive and memory disruptions seen in diseases such as schizophrenia and Alzheimer's, in which gamma waves are disturbed.  |
| Surprise: Lost stem cells naturally replaced by non-stem cells, fly research suggests Posted: 17 Apr 2014 09:41 AM PDT An unexpected phenomenon in the organs that produce sperm in fruit flies has been discovered: When a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out of retirement to replace them. This study has been using the fruit fly as a model living system in which to study stem cells in their natural state. Most stem cell research is done on cells grown in the laboratory, but in real life, stem cells reside in tissues, where they are sequestered in tiny spaces known as niches. Adult stem cells keep dividing throughout life to make various kinds of cells, like new blood cells and germ cells.  |
| Conceptual representation in the brain: Towards mind-reading? Posted: 17 Apr 2014 06:05 AM PDT Your measured brain signals can reveal whether you are thinking about an animal or a tool. That's what neuroscientists discovered during her research, where she investigated the conceptual representation of words and objects in the human brain. This knowledge is useful for the development of tools that convert brain signals into speech.  |
| Distracted driving among teens threatens public health and safety Posted: 17 Apr 2014 06:05 AM PDT Motor vehicle crashes rank as the leading cause of teen deaths and in 2008, 16% of all distraction-related fatal automobile crashes involved drivers under 20 years of age. These grim statistics, coupled with an increasing nationwide awareness of the dangers of distracted driving for all ages, prompted the publication of important research that explores the causes of distracted driving and offers practical recommendations to reduce the incidence of distracted driving among teens.  |
