Engineering a Protein to Prevent Brain Damage from Toxic Agents

July 31, 2014 | Comments

Research at New York University is paving the way for a breakthrough that may prevent brain damage in civilians and military troops exposed to poisonous chemicals—particularly those in pesticides and chemical weapons. The research outlines the advancement in detoxifying organophosphates, which are compounds commonly used in pesticides and warfare agents.

Mosaicism: Study Clarifies Parents as Source of New Mutations

July 31, 2014 3:36 pm | Comments

Scientists have long speculated that mosaicism plays a bigger role in the transmission of rare disease mutations than is currently known. Now, a study sheds new light on the frequency of mosaicism in genomic disorders and its influence on recurrence risk.

Strict Genomic Partitioning by Biological Clock Separates Key Metabolic Functions

July 31, 2014 3:10 pm | Comments

Much of the liver’s metabolic function is governed by circadian rhythms—our own body clock—and UC Irvine researchers have now found two independent mechanisms by which this occurs. The study reveals new information about the body clock’s sway over metabolism and points the way to more focused drug treatments for liver disease and such metabolic disorders as obesity and diabetes.

Drug Target Identified for Common Childhood Blood Cancer

July 31, 2014 12:00 pm | Comments

In what is believed to be the largest genetic analysis of what triggers and propels progression of tumor growth in a common childhood blood cancer, researchers report that they have identified a possible new drug target for treating the disease.

Scientists Zoom In and Out as Brain Processes Sound

July 31, 2014 12:00 pm | 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 | 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 | 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.

Birth Weight and Breastfeeding Have Implications for Children’s Health Decades Later

July 31, 2014 9:20 am | Comments

Young adults who were breastfed for three months or more as babies have a significantly lower risk of chronic inflammation associated with cardiovascular and metabolic diseases, according to research from the Brown School at Washington University in St. Louis.

Team Makes Cancer Glow to Improve Surgical Outcomes

July 30, 2014 1:49 pm | 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.
