Being treated unfairly at work increases risk of long-term sick leave



Posted: 07 Dec 2017 06:42 PM PST


Staff who feel they are treated unfairly at work are at increased risk of being off sick more frequently and for longer, according to new research.


Mindful yoga can reduce risky behaviors in troubled youth



Posted: 07 Dec 2017 03:25 PM PST


Study shows a marked reduction in risky sex and substance abuse in troubled 18- to 24-year-olds after several months of participating in mindful yoga and positive coping strategies.


Discrimination harms your health, and your partner's, study shows



Posted: 07 Dec 2017 12:45 PM PST


Discrimination not only harms the health and well-being of the victim, but the victim's romantic partner as well, indicates new research.


Hope for autism: Optogenetics shines light on social interactions



Posted: 07 Dec 2017 11:17 AM PST


New research, using mice to identify a neural link between spatial learning and socialization, hints at new avenues to help people with autism and other social behavior disorders that affect their prefrontal cortex.


Monkey feel, monkey do: Microstimulation in premotor cortex can instruct movement



Posted: 07 Dec 2017 11:17 AM PST


Finding ways to get around those broken networks in the brain is an important area of research for those seeking to develop treatment interventions. Now researchers are showing in monkeys that stimulation delivered directly to the premotor cortex can elicit a feeling or experience that can instruct different movements, even when the stimulus is too small to induce any response directly.


Why we can't always stop what we've started



Posted: 07 Dec 2017 11:17 AM PST


When we try to stop a body movement at the last second, perhaps to keep ourselves from stepping on what we just realized was ice, we can't always do it -- and neuroscientists have figured out why.


Mutations in neurons accumulate as we age; may explain normal cognitive decline and neurodegeneration



Posted: 07 Dec 2017 11:16 AM PST


Researchers used whole-genome sequencing of individual neurons and found strong evidence that brain mutations accumulate as we age. They also found that mutations accumulate at a higher rate in people with genetic premature aging disorders causing early brain degeneration.


Atlas of developing human brain launched by researchers



Posted: 07 Dec 2017 11:16 AM PST


Scientists have taken the first step towards a comprehensive atlas of gene expression in cells across the developing human brain, making available new insights into how specific cells and gene networks contribute to building this most complex of organs, and serving as a resource for researchers around the world to study the interplay between these genetic programs and neurodevelopmental disorders such as autism, intellectual disability, and schizophrenia.


Electrical stimulation in brain bypasses senses, instructs movement



Posted: 07 Dec 2017 11:16 AM PST


The brain's complex network of neurons enables us to interpret and effortlessly navigate and interact with the world around us. But when these links are damaged due to injury or stroke, critical tasks like perception and movement can be disrupted. New research is helping scientists figure out how to harness the brain's plasticity to rewire these lost connections, an advance that could accelerate the development of neuro-prosthetics.


Canola oil linked to worsened memory and learning ability in Alzheimer's



Posted: 07 Dec 2017 11:16 AM PST


Canola oil is one of the most widely consumed vegetable oils, yet little is known about its health effects. Now, a study links canola oil consumption in the diet with worsened memory, worsened learning ability and weight gain in mice which model Alzheimer's disease. It's the first study to suggest that canola oil is more harmful than healthful for the brain.


Psychologist examines methods of classifying mental disorders



Posted: 07 Dec 2017 10:22 AM PST


A new article presents the challenges in using three major diagnostic manuals from a scientific perspective and offer some recommendations for re-conceptualizing the mental disorders they describe.


Genes behind higher education linked to lower risk of Alzheimer’s



Posted: 07 Dec 2017 06:54 AM PST


Using genetic information, researchers provide new evidence that higher educational attainment is strongly associated with a lower risk of Alzheimer’s disease.


Night owls have larger social networks than early birds



Posted: 07 Dec 2017 06:53 AM PST


Using anonymous mobile phone data, researchers have tapped into patterns in people’s behavior. They have found out that our ‘chronotypes’ – our inherent periods of sleep during a 24-hour-period – correlate with the size of our social networks and how much we are in contact with others and also the kind of chronotypes with whom we interact.


Recreational drug users not what we think



Posted: 07 Dec 2017 06:50 AM PST


A researcher has been investigating why Australians are among the top users of illegal drugs in the world -- and has uncovered some revealing new facts about the motivations of recreational drug users.


Is there a musical method for interpreting speech?



Posted: 07 Dec 2017 06:50 AM PST


Vocoded speech, or distorted speech that imitates voice transduction by a cochlear implant, is used throughout acoustic and auditory research to explore speech comprehension under various conditions. Researchers evaluated whether musicians had an advantage in understanding and reciting degraded speech as compared to nonmusicians.


Brain scans may reveal most effective anti-drug messages



Posted: 07 Dec 2017 06:49 AM PST


What if you could look into the brains of potential drug abusers and see what messages would be most likely to persuade them to 'just say no?' That's the ultimate goal of researchers whose new study scanned the brains of people while they watched anti-drug public service announcements.


Link found between morning sickness, smoking and healthy pregnancies



Posted: 06 Dec 2017 04:37 PM PST


A link between the 'old wives' tale that morning sickness may indicate a healthy pregnancy, and the reason smoking is so detrimental has been found, according to a new review. The article discusses the importance of the hormone endokinin for healthy pregnancies, its role in causing morning sickness, and how its normal function may be adversely affected by smoking, leading to poor outcomes in pregnancy.


Traumatic brain injury causes intestinal damage, study shows



Posted: 06 Dec 2017 02:42 PM PST


A two-way link between traumatic brain injury and intestinal changes has been uncovered by research. These interactions may contribute to increased infections in these patients, and may also worsen chronic brain damage.


Existing cancer medication offers potential to treat Huntington's disease



Posted: 06 Dec 2017 01:23 PM PST


A drug already used to treat certain forms of cancer appears to be an effective therapy for Huntington's disease, and offers a potential pathway to treat other neurodegenerative diseases.


Can diet help reduce disability, symptoms of MS?



Posted: 06 Dec 2017 01:23 PM PST


For people with multiple sclerosis (MS), eating a healthy diet of fruits, vegetables and whole grains may be linked to having less disability and fewer symptoms than people whose diet is less healthy, according to a study.


Cryo-EM reveals 'crown-like' structure of protein responsible for regulating blood flow



Posted: 06 Dec 2017 01:23 PM PST


Scientists have revealed for the first time the atomic-level structure of a promising drug target for conditions such as stroke and traumatic brain injury.


Seizure study sheds light on lasting brain effects in children



Posted: 06 Dec 2017 09:25 AM PST


Prolonged convulsive seizures in childhood could be linked to the development of other brain conditions, a study suggests.


Brain remaps itself in child with double hand transplant



Posted: 06 Dec 2017 06:05 AM PST


The first child to undergo a successful hand transplant also is the first child in whom scientists have detected massive changes in how sensations from the hands are represented in the brain. The brain reorganization is thought to have begun six years before the transplant, when the child had both hands amputated because of a severe infection during infancy. Notably, after he received transplanted hands, the patient's brain reverted toward a more typical pattern.
