Individuals with traumatic brain injury have significantly more difficulty with gist reasoning than traditional cognitive tests, research shows. Using a unique cognitive assessment, these findings indicate that an individual's ability to 'get the gist' after a TBI more strongly predicts daily functionality than traditional cognitive tests alone.

Using multiphoton imaging, researchers are now able to move beyond characterizing the properties of individual cells to investigate how communication among neurons changes over the course of development. In a new paper, researchers report substantial developmental changes in communication among cells that significantly improve the information processing capabilities of the brain.

Taking in such spine-tingling wonders as the Grand Canyon, Sistine Chapel ceiling or Schubert's 'Ave Maria' may give a boost to the body's defense system. Researchers have linked positive emotions -- especially the awe we feel when touched by the beauty of nature, art and spirituality -- with lower levels of pro-inflammatory cytokines.

The roots of children's hunger today may stretch back, in part, to the past childhood trauma of their caregivers. Evidence amassed over the past two decades has demonstrated that stress and deprivation during childhood have lifelong consequences on health, as well as school and job performance. A new small-scale study now suggests a strong relationship between exposure to adverse childhood experiences (ACEs) and household food insecurity among mothers of young children.

Facebook use can lead to symptoms of depression if the social networking site triggers feelings of envy among its users, research shows. "Facebook can be a fun and healthy activity if users take advantage of the site to stay connected with family and old friends and to share interesting and important aspects of their lives," an author said. "However, if Facebook is used to see how well an acquaintance is doing financially or how happy an old friend is in his relationship--things that cause envy among users--use of the site can lead to feelings of depression."

A new study has revealed how children with an aggressive cancer predisposition syndrome experience a never before seen flood of mutations in their disease in just six months. The syndrome, called 'biallelic mismatch repair deficiency' (bMMRD) causes multiple brain tumours, lymphomas and gastrointestinal cancers by the age of 10. As a result these children rarely survive into adulthood.

Both autism and Alzheimer's disease can have tragic consequences for sufferers and their families. Now a new study may offer insight into the pathology of both autism and Alzheimer's by revealing that different activities of certain proteins in males and females cause gender-specific tendencies toward these diseases. The research may lead to new drugs for potential future therapeutics to treat both illnesses.

We all know the type -- people who can talk on and on about their latest adventures, seemingly unaware that those around them may not be interested. They also get really psyched up about their own experiences. A new paper suggests that what separates such people from the rest of us is their perceived sense of power: Powerful people, researchers found, draw inspiration from themselves rather than others.

Among patients with severe trauma and major bleeding, those who received a transfusion of a balanced ratio of plasma, platelets, and red blood cells (RBCs) were more likely to have their bleeding stopped and less likely to die due to loss of blood by 24 hours compared to patients who received a transfusion with a higher ratio of RBCs, according to a study.

Cell-free fetal DNA testing, which measures the relative amount of free fetal DNA in a pregnant woman's blood, is a new screening test that indicates the risk of Down syndrome (trisomy 21), researchers report.

Gene expression within neurons is critical for the formation of memories, but it's difficult to identify genes whose expression is altered by learning. Now researchers have successfully monitored the expression of genes in neurons after rats were exposed to auditory fear conditioning, in which a neutral auditory tone is paired with electric shock.

The daily rhythm of bone turnover is likely important for normal bone health, and recent research suggests that sleep apnea may be an unrecognized cause of some cases of osteoporosis. Sleep apnea's effects on sleep duration and quality, oxygen levels, inflammation, and other aspects of health may have a variety of impacts on bone metabolism, experts say.

When reminded, or primed, of past winning outcomes as part of a controlled test, people were over 15% more likely to gamble and select the risky option. Surprisingly, being reminded of past losing outcomes did not change their gambling behavior.

Access to state-supported early childhood programs significantly reduces the likelihood that children will be placed in special education in the third grade, academically benefiting students and resulting in considerable cost savings to school districts, according to new research.

A collection of simple strategies used by parents can lead to significant improvements in one-year-olds at risk for autism spectrum disorder (ASD), researchers have found. The study followed 18 families with a one-year-old child at risk for ASD. Researchers compared the effects of a parent-coaching, home-based intervention called "Adapted Responsive Teaching" (ART) versus referral to early intervention and monitoring.

As the U.S. Food and Drug Administration is preparing to issue a final ruling on whether it will extend its tobacco regulatory authority to electronic cigarettes (e-cigarettes), researchers have identified strong support for a number of e-cigarette policies among smokers. Findings included strong support for advertising restrictions and placing warning labels for potential risks on the devices.

Precision medicine is getting a jump-start from a new national initiative announced in President Obama's State of the Union message. One Georgia family has already experienced its benefits: genomic testing called whole exome sequencing helped a neurologist solve a medical mystery that had left a boy with painful, jerking spasms that at times prevented him from walking or talking. The doctor describes the case in a newly published article.

The disruptiveness of the noise generated by wind power plants in Finland is the focus of a new study that combines the measurement of the noise produced by wind power with the noise experienced by humans in relation to sound pressure levels and the time and frequency behavior of sound.

A new study heightens concerns over the detrimental impact of the apolipoprotein E (APOE) ?4 allele -- the most prevalent genetic risk for Alzheimer’s disease -- upon cognition, olfaction, and metabolic brain indices in healthy urban children and teens.

Evidence that cooking foods at high temperatures increases the risk of Alzheimer's disease has been gained through a new study. This study looked at the content of advanced glycation end products (AGEs) in national diets and clinical studies comparing and compared total AGEs to Alzheimer's disease rates.

Grasping an object involves a complex network of brain functions. First, visual cues are processed in specialized areas of the brain. Then, other areas of the brain use these signals to control the hands to reach for and manipulate the desired object. New findings suggest that the cerebellum, a region of the brain that has changed very little over time, may play a critical role. Findings could lead to advancements in assistive technologies benefiting the disabled.
