Older adult clumsiness linked to brain changes 2013-06-17

By Washington University in St. Louis

For many older adults, the aging process seems to go hand-in-hand with an annoying increase in clumsiness. New research suggests some of these reaching-and-grasping difficulties may be caused by changes in the mental frame of reference that older adults u

Insights into a debilitating brain disease 2013-06-17

By University of Georgia

From the neurons that enable thought to the keratinocytes that make toenails grow -- a complex canopy of sugar molecules, commonly known as glycans, envelop every living cell in the human body. These complex carbohydrate chains perform a host of vital fun

Test to improve stem cell safety 2013-06-17

By CSIRO Australia

Scientists have developed a test to identify unsafe stem cells. It is the first safety test specifically for human induced pluripotent stem cells.

Evolutionary history of a cancer-related gene 2013-06-17

By Centro Nacional de Investigaciones Oncologicas (CNIO)

Scientists have described how a genetic duplication that took place in the vertebrate ancestor some 500 million years ago encouraged the evolution of the ASF1b gene; a gene essential for proper cell division and related to some types of cancer such as bre

Targeting an aspect of Down syndrome 2013-06-17

By University of Michigan

Researchers have determined how a gene that is known to be defective in Down syndrome is regulated and how its dysregulation may lead to neurological defects, providing insights into potential therapeutic approaches to an aspect of the syndrome.

Brain imaging study eliminates differences in visual function as a cause of dyslexia 2013-06-17

By Georgetown University Medical Center

A new brain imaging study of dyslexia shows that visual system differences do not cause the disorder, but instead are likely a consequence.

Cognitive ability differences among the elderly explained 2013-06-17

By McGill University

A new study shows compelling evidence that associations between cognitive ability and cortical grey matter in old age can largely be accounted for by cognitive ability in childhood.

Half of those diagnosed with PTSD also suffer from depression 2013-06-17

By Case Western Reserve University

About one of every two people diagnosed with posttraumatic stress disorder also suffer symptoms of depression, according to new research.

New technique for deep brain stimulation surgery proves accurate and safe 2013-06-17

By Oregon Health & Science University

The surgeon who more than two decades ago pioneered deep brain stimulation surgery in the United States to treat people with Parkinson's disease and other movement disorders has now developed a new way to perform the surgery -- which allows for more accur

Stem cell study could aid quest to combat range of diseases 2013-06-17

By University of Edinburgh

Scientists have taken a vital step forward in understanding how cells from skin tissue can be reprogrammed to become stem cells.

Zebrafish help identify mutant gene in rare muscle disease 2013-06-17

By University of Michigan

Zebrafish with very weak muscles helped scientists decode the elusive genetic mutation responsible for Native American myopathy, a rare, hereditary muscle disease that afflicts Native Americans in North Carolina.

Nontoxic cancer therapy proves effective against metastatic cancer 2013-06-17

By University of South Florida (USF Health)

A combination of dietary and hyperbaric oxygen therapies effectively increased survival time in a mouse model of aggressive metastatic cancer, a new research team found. The study demonstrates the potential of these cost-effective, nontoxic therapies to p

Risk of kidney disease doubled with use of fluoroquinolone antibiotics 2013-06-17

By Canadian Medical Association Journal

The risk of acute kidney disease is doubled for people taking oral fluoroquinolone antibiotics, according to a new study.

Enhancer RNAs alter gene expression: New class of molecules may be key emerging 'enhancer therapy' 2013-06-17

By University of California, San Diego Health Sciences

In a pair of distinct but complementary papers, researchers illuminate the functional importance of a relatively new class of RNA molecules. The work suggests modulation of “enhancer-directed RNAs” or “eRNAs” could

Anxious? Activate your anterior cingulate cortex with a little meditation 2013-06-17

By Wake Forest Baptist Medical Center

Scientists, like Buddhist monks and Zen masters, have known for years that meditation can reduce anxiety, but not how. Scientists have now succeeded in identifying the brain functions involved.

Wolbachia bacteria evolved to infect stem cell niches through successive generations of their hosts 2013-06-17

By Boston University College of Arts & Sciences

A new study provides evidence that Wolbachia target the ovarian stem cell niches of its hosts -- a strategy previously overlooked to explain how Wolbachia thrive in nature.

One in four patients with newly-diagnosed erectile dysfunction is a young man 2013-06-17

By Wiley

In a recent analysis of one outpatient clinic, one in four men seeking medical help for newly-developed erectile dysfunction (ED) was younger than 40 years, and nearly half of young men with the condition had severe ED. While larger population-based studi

Researchers focus on a brain protein and an antibiotic to block cocaine craving 2013-06-17

By Indiana University

A new study by neuroscientists demonstrates that GLT1, a protein that clears glutamate from the brain, plays a critical role in the craving for cocaine that develops after only several days of cocaine use.

Candidate drug provides benefit in spinal muscular atrophy animal models 2013-06-17

By Children's Memorial Hospital

The drug RG3039 demonstrates that it can extend survival and improve function in two spinal muscular atrophy mouse models.

Time limits on welfare can lead to higher mortality rates 2013-06-17

By Columbia University's Mailman School of Public Health

US workfare programs have been praised for improving the economic well-being of families but little is known about how these policies affected participants' health and mortality. In a study of enrollees in Florida's Family Transition Program who were give
