Scientists Zoom In and Out as Brain Processes Sound

July 31, 2014 12:00 pm | News | Comments

Researchers have mapped the sound-processing part of the mouse brain in a way that keeps both the proverbial forest and the trees in view. Their technique allows zooming in and out on views of brain activity within mice, and it enabled the team to watch brain cells light up as mice “called” to each other.

Autistic Brain Less Flexible at Taking on Tasks

July 31, 2014 9:41 am | News | Comments

The brains of children with autism are relatively inflexible at switching from rest to task performance, according to a new study. Instead of changing to accommodate a job, connectivity in key brain networks of autistic children looks similar to connectivity in the resting brain. And the greater this inflexibility, the more severe the child’s manifestations of repetitive and restrictive behaviors that characterize autism, the study found.

Dissolvable Fabric Loaded with Medicine Might Offer Faster Protection Against HIV

July 31, 2014 9:27 am | News | Comments

University of Washington bioengineers have discovered a potentially faster way to deliver a topical drug that protects women from contracting HIV. Their method spins the drug into silk-like fibers that quickly dissolve when in contact with moisture, releasing higher doses of the drug than possible with other topical materials such as gels or creams.

Kids with Autism, SPD Show Differences in Brain Wiring

July 31, 2014 8:30 am | News | Comments

Researchers have found that children with sensory processing disorders have decreased structural brain connections in specific sensory regions different than those in autism, further establishing SPD as a clinically important neurodevelopmental disorder.

Team Makes Cancer Glow to Improve Surgical Outcomes

July 30, 2014 1:49 pm | News | Comments

The best way to cure most cases of cancer is to surgically remove the tumor. The Achilles heel of this approach, however, is that the surgeon may fail to extract the entire tumor, leading to a local recurrence. With a new technique, researchers at the University of Pennsylvania have established a new strategy to help surgeons see the entire tumor in the patient, increasing the likelihood of a positive outcome.

Midlife Problem Drinking Doubles Chance of Memory Issues

Deadly Melanoma Cases Jump 200%, Report Says

July 30, 2014 8:22 am | by Anne Flaherty - Associated Press - Associated Press | News | Comments

Stop sunbathing and using indoor tanning beds, the acting U.S. surgeon general warned in a report released Tuesday that cites an alarming 200 percent jump in deadly melanoma cases since 1973.                 

Advance in Capturing Elusive Circulating Tumor Cells

July 29, 2014 3:33 pm | by Cynthia Fox | Articles | Comments

When cancers spread into the bloodstream, they often take on different characteristics, requiring different therapies. But it is hard to find these rare blood-borne cells. So, relapsed patients often do not get personalized care. Now, researchers have come up with a solution that zeros in on elusive circulating tumor cells (CTCs).

New Gene Function Discovery Offers Clues to ALS

July 29, 2014 12:11 pm | News | Comments

Researchers have found a missing link that helps to explain how ALS, one of the world’s most feared diseases, paralyses and ultimately kills its victims. The breakthrough is helping them trace a path to a treatment or even a cure.       

LFMS Shows Immediate Results as Depression Treatment

Individuals with major depressive disorder or bipolar disorder who receive low-field magnetic stimulation (LFMS) show immediate and substantial mood improvement, researchers report.                    

Memory Relies on Astrocytes

July 29, 2014 11:46 am | Videos | Comments

When you're expecting something— like the meal you've ordered at a restaurant— or when or when something captures your interest, unique electrical rhythms called gamma oscillations sweep through your brain. New research shows that little known supportive cells in the brain known as astrocytes may in fact be major players that control these waves.

Cell's Recycling Center Implicated in Division Decisions

July 29, 2014 11:37 am | News | Comments

Researchers have identified a mechanism that overrides the cells’ warning signals, enabling cancers to continue to divide even without a robust blood supply.                           

New Protein Structure Could Help Treat Alzheimer’s

July 29, 2014 11:23 am | News | Comments

Bioengineers have designed a peptide structure that can stop the harmful changes of the body’s normal proteins into a state that’s linked to widespread diseases such as Alzheimer’s, Parkinson’s, heart disease, Type 2 diabetes and Lou Gehrig’s disease.
