Copper Identified as Culprit in Alzheimer's Disease

August 20, 2013 11:12 am | by University of Rochester Medical Center | News | Comments

Copper appears to be one of the main environmental factors that trigger the onset and enhance the progression of Alzheimer's disease by preventing the clearance and accelerating the accumulation of toxic proteins in the brain. That is the conclusion of a study appearing today in the journal Proceedings of the National Academy of Sciences.

How Brain Microcircuits Integrate Information from Different Senses

New Tool Peeks into Brain to Measure Consciousness

August 15, 2013 10:40 am | by Lauran Neergaard, AP Medical Writer | News | Comments

When people have a brain injury so severe that they can't squeeze a loved one's hand or otherwise respond, there are few good ways to tell if they have any lingering awareness or are in a vegetative state. Now researchers have created a tool to peek inside the brain and measure varying levels of consciousness.

Inducing Labor May Be Tied to Autism, Study Says

August 14, 2013 2:20 pm | by Lindsey Tanner, AP Medical Writer | News | Comments

The biggest study of its kind suggests autism might be linked with inducing and speeding up labor, preliminary findings that need investigating since labor is induced in increasing numbers of U.S. women. It's possible that labor-inducing drugs might increase the risk — or that the problems that lead doctors to start labor explain the results.

Brain Scans May Help Diagnose Dyslexia

August 14, 2013 11:24 am | by Anne Trafton, MIT News Office | News | Comments

About 10 percent of the U.S. population suffers from dyslexia, a condition that makes learning to read difficult. Dyslexia is usually diagnosed around second grade, but the results of a new study from MIT could help identify those children before they even begin reading, so they can be given extra help earlier.

Ambient Backscatter Eliminates Power Needs for Wireless Device Communication

August 13, 2013 5:18 pm | by University of Washington | Videos | Comments

University of Washington engineers have created a new wireless communication system that allows devices to interact with each other without relying on batteries or wires for power. The new communication technique, which the researchers call “ambient backscatter,” takes advantage of the TV and cellular transmissions that already surround us around the clock.

Stopping Alzheimer Before the First Symptoms

August 13, 2013 11:14 am | by Ciência Viva - Agência Nacional para a Cultura Científica e Tecnológica | News | Comments

New research opens the door for the development of treatments capable of stopping Alzheimer’s disease before its first symptoms, that is to say before any crucial damage occurs. In fact, if AD is a devastating disorder, it is also an extremely slow one; it takes more than 10 years for the first symptoms to appear, making this preclinical period the ideal time to intervene.

Dissolvable Sutures Material Could Treat Brain Infections

August 13, 2013 10:37 am | by ACS Chemical Neuroscience | News | Comments

A plastic material already used in absorbable surgical sutures and other medical devices shows promise for continuous administration of antibiotics to patients with brain infections, scientists are reporting in a new study. Use of the material, placed directly on the brain’s surface, could reduce the need for weeks of costly hospital stays now required for such treatment.
