MRI reveals genetic activity: Deciphering genes' roles in learning and memory Doctors commonly use magnetic resonance imaging (MRI) to diagnose tumors, damage from stroke, and many other medical conditions. Neuroscientists also rely on it as a research tool for identifying parts of the brain that carry out different cognitive functions. Now, biological engineers are trying to adapt MRI to a much smaller scale, allowing researchers to visualize gene activity inside the brains of living animals.
Exploring Brain for Keys to Solving Parkinson's Disease One of the final frontiers of science is the human brain. The brain is the source of our intelligence, feelings and ability to make our bodies move – as well as the locus of terrible diseases such as Parkinson's and Alzheimer's – and is as complicated as any object that scientists explore. Parkinson's disease, which experts say affects more than six million people around the world, can progressively degrade many of those functions, a primary reason why a team of researchers has been given a grant to delve ever more deeply into the circuitry and function of the striatum.
Recreational drug users who switch from ecstasy to mephedrone don't understand dangers Contrary to popular belief among recreational drug users, mephedrone has several important differences when compared with MDMA, commonly known as ecstasy. These differences mean that mephedrone could leave a user with acute withdrawal symptoms and indicate that it may have a higher potential for developing dependence than MDMA according to a study.

Types of Imagery and How to Use Visualization to Achieve Your Goals Imagery classified to help you visualize better and achieve your goals. Find out how mental images can be classified in terms of focus and perspective as well as bodily sensations and experiences to make picture more realistic.
Eating Disorders in the Online World The internet can be a dangerous place where people suffering from eating disorders offer each other encouragement to be ill "˜better'. What are the forces driving this worrying development, and what can we do about it?read more
Good quality sleep crucial to mental health and wellbeing Having a good quality and restorative sleep is essential for one to be able to function well throughout the day. Failure to do so will lead to numerous impacts to health, both long- and short-term.
Coerced Sex Not Uncommon for Young Men, Teenage Boys, Study Finds Result is distress and risky behavior, but not lower self-esteem, according to research
NFL hopes camp for moms will prevent concussions in kids The NFL believes if mothers know how to tackle properly, they can make sure their kids do, too.
Activity levels in mothers and children 'directly linked' Study suggests policies to improve children's health should be aimed at mothers.
High levels of long-term stress linked to two-fold increased risk of infertility Long-term stress may reduce a woman's ability to conceive by as much as 29 percent, a new study reports.
Study shows violent video games may be tied to aggressive thoughts Kids who often play violent video games may show more aggression later on, and more often believe hitting is acceptable, than kids who don't play them.
New depths of complexity in nerve cells discovered The protein CaM Kinase II plays a significant role in controlling when and where neuropeptides are released from neurons, researchers have found using mutant C. elegans. Using a method called "forward genetics," the researchers randomly screened thousands of mutant worms for defects in neuropeptide storage and unexpectedly identified mutant worms lacking CaM Kinase II. Further analysis revealed that CaM Kinase II plays a significant role in controlling when and where neuropeptides are released from neurons.
Fundamentals of facial recognition: Specialized brain mechanisms for recognizing faces? Scientists showed that participants suffering from face blindness performed as well as the average person in training measuring their ability to learn a set of computer-generated objects called greebles. The findings undermine the leading alternative to the idea that prosopagnosia is the result of damage to brain mechanisms specifically devoted to processing faces, and thus indicate that people recognize faces using face-specific brain mechanisms.
For neurons in the brain, identity can be used to predict location There are many types of neurons, defined largely by the patterns of genes they use, and they 'live' in distinct brain regions. But researchers do not yet have a comprehensive understanding of these neuronal types and how they are distributed in the brain. A team of scientists describes a new mathematical model that combines large data sets to predict where different types of cells are located within the brain.
How does one cope with ambiguous loss? The case of the disappeared Malaysian Airlines Flight MH370 The continuing confusion and lack of definitive information about the whereabouts of Malaysian Airline MH370 for over two weeks (when this post is written), has focused the world-s attention on the suffering of the family and friends of the 239 missing passengers. It is difficult to even imagine what these family members and friends are going through. This article looks at how we can help those coping with an ambiguous loss such as is the case for the family and loved ones of those missing on MH370.

No longer junk: Role of long noncoding RNAs in autism risk RNA acts as the intermediary between genes and proteins, but the function of pieces of RNA that do not code for protein has, historically, been less clear. Researchers have ignored these noncoding RNAs until recently for not complying with the central dogma of biology "” that a straight line runs from gene to RNA (transcription) to protein (translation). However, noncoding RNAs are emerging as important regulators of diverse cellular processes with implications for numerous human disorders.
