Researchers at Columbia University Medical Center (CUMC) have identified a brain receptor that appears to play a central role in regulating appetite. The findings, published today in the online edition of Cell, could lead to new drugs for preventing or treating obesity.

A team of Idaho State University researchers have discovered that fish show autism-like gene expression after exposure to water containing psychoactive pharmaceuticals. The results may suggest an environmental trigger for autism, although this finding may only apply to genetically predisposed individuals.

The brain receives information from the ear in a surprisingly orderly fashion, according to a University at Buffalo study scheduled to appear June 6 in the Journal of Neuroscience. The research focuses on a section of the brain called the cochlear nucleus, the first way-station in the brain for information coming from the ear. In particular, the study examined tiny biological structures called synapses that transmit signals from the auditory nerve to the cochlear nucleus.

Using translucent zebrafish larvae the researchers were able to visualise how white blood cells interact with the early cancer cell formation as they arise in tissues.

Wearing a robotic harness, paralyzed rats have been made to walk again, according to a new studyalbeit with an oddly upright, humanlike gait and while stimulated by judicious jolts of electricity and chemicals. It's the first time severely injured spinal cords have been reawakened, say researchers, who add that the technique might hold some promise for disabled people.

The tuberculosis vaccine is often used as a treatment for bladder cancer, and adding vitamin D might improve the vaccine’s effectiveness, according to new research from the University of Rochester Medical Center .

Researchers have shown in mice how immune cells in the brain target and remove unused connections between brain cells during normal development. This research, supported by the National Institutes of Health, sheds light on how brain activity influences brain development, and highlights the newly found importance of the immune system in how the brain is wired, as well as how the brain forms new connections throughout life in response to change.

Is it possible that liposuction or other fat removal procedures are beneficial for treating obesity and reducing the risk of cancer?

When it comes to humans, scientists can’t answer that question. They know that obesity increases the risk of heart disease, diabetes and cancer.  But there have not been clinical studies to determine if the surgical removal of fat tissue would decrease cancer risk in humans.

Scientists at Queen Mary, University of London have shown that zebrafish could be used to study the underlying causes of psychiatric disorders.

A project that maps dopamine circuits in the prefrontal cortex through optogenetic manipulation was given top honors in this year's annual Addiction Science Awards at the 2012 Intel International Science and Engineering Fair (ISEF) — the world's largest science competition for high school students.

Scientists at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa (uOttawa) have discovered that mice that lack a gene called Snf2l have brains that are 35 per cent larger than normal. The research, led by Dr. David Picketts and published in the prestigious journal Developmental Cell, could lead to new approaches to stimulate brain regeneration and may provide important insight into developmental disorders such as autism and Rett syndrome.

For decades, scientists have studied Caenorhabditis elegans – tiny, transparent worms – to glean clues about how neurons develop and function. A new Harvard study suggests that the worms' nervous system is much more capable and complex than previously thought, and has a way to monitor its own motion, a model one day could serve to develop treatments for disorders like schizophrenia.

An experimental therapy that reprograms the immune system then spurs the growth of healthy insulin-producing cells reversed late-stage diabetes in mice and may lead to a cure for people, researchers said.

According to a 2011 statement by the Centers for Disease Control and Prevention, nearly one in 10 American children is diagnosed with ADHD. To better understand the cause of ADHD and to identify methods to prevent and treat it, researchers at Oregon Health & Science University (OHSU) and OHSU's Oregon National Primate Research Center have developed a new form of specially bred mouse that mimics the condition.

 In the battle against obesity, brown fat appears to be our friend and white fat our foe. Now a team of researchers led by Jorge Plutzky, MD, director of The Vascular Disease Prevention Program at Brigham and Women's Hospital (BWH) and Harvard Medical School has discovered a way to turn foe to friend.
