Brain

JACKSONVILLE, Fla. — Using a new and powerful approach to understand the origins of neurodegenerative disorders such as Alzheimer's disease, researchers at Mayo Clinic in Florida are building the case that these diseases are primarily caused by genes that are too active or not active enough, rather than by harmful gene mutations.

WORCESTER, MA – Degeneration of the axon and synapse, the slender projection through which neurons transmit electrical impulses to neighboring cells, is a hallmark of some of the most crippling neurodegenerative and brain diseases such as amyotrophic lateral sclerosis (ALS), Huntington's disease and peripheral neuropathy. Scientists have worked for decades to understand axonal degeneration and its relation to these diseases.

URBANA –Teachers learn a lot about how to teach curriculum in college, but they don't get much training in helping very young children learn to handle frustration, anger, and excitement, skills that kids need for kindergarten readiness, said Nancy McElwain, a University of Illinois professor of human development and family studies who conducted a study on the topic.

Developmental psychology researchers have long known that children aren't simply mini-adults – their minds and brains work in fundamentally different ways. Exploring those differences can help us understand how kids think and behave and can provide insights into how the mind and brain develop and change over time. Here is some of the latest research involving children from Psychological Science, a journal of the Association for Psychological Science.

Who is Good At This Game? Linking an Activity to a Social Category Undermines Children's Achievement

SAN FRANCISCO, CA—June 7, 2012—Scientists at the Gladstone Institutes have for the first time transformed skin cells—with a single genetic factor—into cells that develop on their own into an interconnected, functional network of brain cells. The research offers new hope in the fight against many neurological conditions because scientists expect that such a transformation—or reprogramming—of cells may lead to better models for testing drugs for devastating neurodegenerative conditions such as Alzheimer's disease.

New York, NY (June 7, 2012) — 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 study led by Karolinska Institutet in Sweden reports for the first time the positive effects of an active vaccine against Alzheimer's disease. The new vaccine, CAD106, can prove a breakthrough in the search for a cure for this seriously debilitating dementia disease. The study is published in the distinguished scientific journal Lancet Neurology.

SALT LAKE CITY, June 6, 2012 – Talk about throwing yourself into a relationship too soon.

A University of Utah study found that when a virgin male moth gets a whiff of female sex attractant, he's quicker to start shivering to warm up his flight muscles, and then takes off prematurely when he's still too cool for powerful flight. So his headlong rush to reach the female first may cost him the race.

Evarcha culicivora jumping spiders, also known as vampire spiders, are picky eaters by any standards. Explaining that the arachnid's environment is swamped with insects, Ximena Nelson from the University of Canterbury, New Zealand, says, 'You can see from the diet when you find them in the field that there is a high number of mosquitoes in what they eat'. And when Robert Jackson investigated their diet further, he found that the spiders were even more selective. The delicacy that E.

Tampa, Fla. (June 6, 2012) – Two studies appearing in thecurrent issue of Cell Transplantation (21:2/3), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/, evaluate the transplantation potential and success of islet cells derived from pancreatic tissues, in addition to a clinical study that reports the occurrence of adverse events.

Fresh islets are better than cultured islets

An Indiana University biologist has shown that natural variation in measures of the brain's ability to process steroid hormones predicts functional variation in aggressive behavior.

MADISON — Stress may affect brain development in children — altering growth of a specific piece of the brain and abilities associated with it — according to researchers at the University of Wisconsin–Madison.

CHAPEL HILL, N.C. – New research by scientists at the University of North Carolina School of Medicine may have pinpointed an underlying cause of the seizures that affect 90 percent of people with Angelman syndrome (AS), a neurodevelopmental disorder.

Published online Thursday June 7, 2012 in the journal Neuron, researchers led by Benjamin D. Philpot, PhD, professor of cell and molecular physiology at UNC, describe how seizures in individuals with AS could be linked to an imbalance in the activity of specific types of brain cells.

Even when brain injury is so subtle that it can only be detected by an ultra-sensitive imaging test, the injury might predispose soldiers in combat to post-traumatic stress disorder, according to a University of Rochester Medical Center study.

A lucky rabbit foot. A glass of wine. A pill. What do these things all have in common? Their effects – whether we do well on a test, whether we mingle at the cocktail party, whether we feel better – all depend on the power of suggestion.
