Addicted to tanning?

BOWLING GREEN, O.—They keep tanning, even after turning a deep brown and experiencing some of the negative consequences. Skin cancer is among the most common, preventable types of the disease, yet many continue to tan to excess.

Family problems experienced in childhood and adolescence affect brain development

New research has revealed that exposure to common family problems during childhood and early adolescence affects brain development, which could lead to mental health issues in later life.

A*STAR scientists discover protein's role in human memory and learning functions

1. Scientists at A*STAR's Institute of Molecular and Cell Biology (IMCB) have identified the precise role of the protein, SNX27, in the pathway leading to memory and learning impairment. The study broadens the understanding of the brain's memory function and could be used to explain defects in the cognitive development of those with Down's syndrome. The newly established knowledge could potentially facilitate exploration of strategies to improve memory and learning abilities in Down's syndrome.

Dreams, deja vu and delusions caused by faulty 'reality testing'

New research from the University of Adelaide has delved into the reasons why some people are unable to break free of their delusions, despite overwhelming evidence explaining the delusion isn't real.

Chronic pain relief more likely when psychological science involved

WASHINGTON - When it comes to chronic pain, psychological interventions often provide more relief than prescription drugs or surgery without the risk of side effects, but are used much less frequently than traditional medical treatments, according to a comprehensive review published by the American Psychological Association.

A circuit for change

To answer the seemingly simple question "Have I been here before?" we must use our memories of previous experiences to determine if our current location is familiar or novel. In a new study published in the Journal of Neuroscience researchers from the RIKEN Brain Science Institute have identified a region of the hippocampus, called CA2, which is sensitive to even small changes in a familiar context. The results provide the first clue to the contributions of CA2 to memory and may help shed light on why this area is often found to be abnormal in the schizophrenic brain.

Research of zebrafish neurons may lead to understanding of birth defects like spina bifida

COLUMBIA, Mo. – The zebrafish, a tropical freshwater fish similar to a minnow and native to the southeastern Himalayan region, is well established as a key tool for researchers studying human diseases, including brain disorders. Using zebrafish, scientists can determine how individual neurons develop, mature and support basic functions like breathing, swallowing and jaw movement. Researchers at the University of Missouri say that learning about neuronal development and maturation in zebrafish could lead to a better understanding of birth defects such as spina bifida in humans.

Can you boost your brain power through video?

PHILADELPHIA – Watching video of simple tasks before carrying them out may boost the brain's structure, or plasticity, and increase motor skills, according to a study released today that will be presented at the American Academy of Neurology's 66th Annual Meeting in Philadelphia, April 26 to May 3, 2014. Brain plasticity is the brain's ability to flex and adapt, allowing for better learning. The brain loses plasticity as it ages.

Neuropsychological assessment more efficient than MRI for tracking disease progression

Amsterdam, NL, February 18, 2014 – Investigators at the University of Amsterdam, The Netherlands, have shown that progression of disease in memory clinic patients can be tracked efficiently with 45 minutes of neuropsychological testing. MRI measures of brain atrophy were shown to be less reliable to pick up changes in the same patients.

SDSC/UC San Diego researchers hone in on Alzheimer's disease

Researchers studying peptides using the Gordon supercomputer at the San Diego Supercomputer Center (SDSC) at the University of California, San Diego (UCSD) have found new ways to elucidate the creation of the toxic oligomers associated with Alzheimer's disease.

Igor Tsigelny, a research scientist with SDSC, the UCSD Moores Cancer Center, and the Department of Neurosciences, focused on the small peptide called amyloid-beta, which pairs up with itself to form dimers and oligomers.

Wistar scientists develop gene test to accurately classify brain tumors

cientists at The Wistar Institute have developed a mathematical method for classifying forms of glioblastoma, an aggressive and deadly type of brain cancer, through variations in the way these tumor cells "read" genes. Their system was capable of predicting the subclasses of glioblastoma tumors with 92 percent accuracy. With further testing, this system could enable physicians to accurately predict which forms of therapy would benefit their patients the most.

Personality and spaces, remaking love, meaning in life, and commonsense morality

People and spaces, the tragedy of commonsense morality, myths about meaning of life, and remaking love were four themes at the Society for Personality and Social Psychology (SPSP) conference in Austin. Researchers presented new work, showing how psychology reaches into our everyday lives. Video from four of these talks is now available online.

Researchers discover how ALS spreads

A study led by University of British Columbia and Vancouver Coastal Health Research Institute researchers has revealed how the fatal neurodegenerative disease amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is transmitted from cell to cell, and suggests the spread of the disease could be blocked.

Study uncovers surprising differences in brain activity of alcohol-dependent women

BLOOMINGTON -- A new Indiana University study that examines the brain activity of alcohol-dependent women compared to women who were not addicted found stark and surprising differences, leading to intriguing questions about brain network functions of addicted women as they make risky decisions about when and what to drink.

Frequent school moves can increase the risk of psychotic symptoms in early adolescence

Researchers at Warwick Medical School have shown that frequently moving schools during childhood can increase the risk of psychotic symptoms in later years.

The study, published in the Journal of American Academy of Child and Adolescent Psychiatry, found that school mobility during childhood heightens the risk of developing psychotic-like symptoms in early adolescence by up to 60%.

Suffering from psychotic-like symptoms at young age is strongly associated with mental health problems in adulthood, including psychotic disorders and suicide.
