It only takes one bad apple to spoil the bunch, and the same may be true of certain proteins in the brain. Studies have suggested that just one rogue protein (in this case, a protein that is misfolded or shaped the wrong way) can act as a seed, leading to the misfolding of nearby proteins. According to an NIH-funded study, various forms of these seeds — originating from the same protein — may lead to different patterns of misfolding that result in neurological disorders with unique sets of symptoms.

Jena (Germany) Spain, France and Great Britain – these are the favourite countries of young Germans who study abroad under the ERASMUS programme. More and more German students consider one or two terms at a university abroad an essential part of their CVs. As a consequence, the number of students who spent some time at a foreign university has more than doubled over the last few years and it is estimated that about a quarter of all German students have gained some form of international experiences.
Scientists at the University of Liverpool have shown that young people who show impulsive tendencies are more prone to drinking heavily at an early age.
The research suggests that targeting personality traits, such as impulsivity, could potentially be a successful intervention in preventing adolescent drinking from developing into problems with alcohol in later life.
Studies in the UK show that approximately 24% of 12 year olds have reported at least one episode of alcohol consumption, rising to 77% of 15 year olds.
In 2000, researchers at the UCLA Center for Sleep Research published findings showing that people suffering from narcolepsy, a disorder characterized by uncontrollable periods of deep sleep, had 90 percent fewer neurons containing the neuropeptide hypocretin in their brains than healthy people. The study was the first to show a possible biological cause of the disorder.
Brain aneurysms of all sizes — even small ones the size of a pea — are up to 12 times more likely to rupture if they are growing, according to a new UCLA study.
Published July 2 in the online edition of the journal Radiology, the discovery counters current guidelines suggesting that small aneurysms pose a low risk for rupture, and it emphasizes the need for regular monitoring and earlier treatment.
If you rely on hand gestures to get your point across, you can thank fish for that! Scientists have found that the evolution of the control of speech and hand movements can be traced back to the same place in the brain, which could explain why we use hand gestures when we are speaking.
DURHAM, N.C. -- You might be falling in love with that new car, but you probably wouldn't pay as much for it if you could resist the feeling.
Researchers at Duke University who study how the brain values things -- a field called neuroeconomics -- have found that your feelings about something and the value you put on it are calculated similarly in a specific area of the brain.
Amsterdam, NL, July 2, 2013 – Multiple sclerosis (MS) can lead to severe cognitive impairment as the disease progresses. Researchers in Italy have found that patients with high educational levels show less impairment on a neuropsychological evaluation compared with those with low educational levels. Their results are published in Restorative Neurology and Neuroscience.
In the first study to compare all available IVF treatments and the risk of neurodevelopmental disorders in children, researchers find that IVF treatments for the most severe forms of male infertility are associated with an increased risk of intellectual disability and autism in children.
Autism and intellectual disability remain a rare outcome of IVF, and whilst some of the risk is associated with the risk of multiple births, the study provides important evidence for parents and clinicians on the relative risks of modern IVF treatments.
More people die from heart-disease during the winter months, and according to a new study published in the journal Cell Metabolism, the increase in mortality is possibly due to the accelerated growth of atherosclerotic plaque in the blood vessels caused by the activation of brown fat by the cold.
PITTSBURGH -- Older adults diagnosed with brain disorders such as Parkinson's disease often feel a loss of independence because of their lack of mobility and difficulty walking. To better understand and improve these mobility issues—and detect them sooner—a University of Pittsburgh multidisciplinary research team is working toward building a more advanced motion test that addresses a wider range of walking patterns and movements.
STANFORD, Calif. —An existing FDA-approved drug improves cognitive function in a mouse model of Down syndrome, according to a new study by researchers at the Stanford University School of Medicine.
The drug, an asthma medication called formoterol, strengthened nerve connections in the hippocampus, a brain center used for spatial navigation, paying attention and forming new memories, the study said. It also improved contextual learning, in which the brain integrates spatial and sensory information.
Employers are increasingly using Facebook to screen job applicants and weed out candidates they think have undesirable traits. But a new study from North Carolina State University shows that those companies may have a fundamental misunderstanding of online behavior and, as a result, may be eliminating desirable job candidates.
On July 2nd, JoVE will publish a video article showing the details of a technique developed by researchers to improve language function in stroke patients with chronic speech-language impairment.
CHAPEL HILL, N.C. -- Researchers have pinpointed the role of a gene known as Arl13b in guiding the formation and proper placement of neurons in the early stages of brain development. Mutations in the gene could help explain brain malformations often seen in neurodevelopmental disorders.
The research, led by a team at the University of North Carolina School of Medicine, was published June 30 in the journal Nature Neuroscience.
