A defect in how proteins are transported inside cells may be at least partially responsible for some symptoms of amyotrophic lateral sclerosis, according to a new study.


Differences in Brain Structure and Memory Suggest Adolescents May Not ‘Grow Out of’ ADHD

August 28, 2015 10:10 am | by University of Cambridge | Comments

Young adults diagnosed with attention deficit/hyperactivity disorder (ADHD) in adolescence show differences in brain structure and perform poorly in memory tests compared to their peers, according to new research.


Vitamin D May Play Key Role in Preventing Macular Degeneration

August 28, 2015 9:30 am | by University at Buffalo | Comments

Vitamin D has been studied extensively in relation to bone health as well as cancer. Now, a team has discovered that vitamin D may play a significant role in eye health, specifically in the possible prevention of age-related macular degeneration, or AMD, among women who are more genetically prone to developing the sight-damaging disease.


Cells Cling and Spiral ‘Like Vines’ in First 3D Tissue Scaffold for Plants

August 27, 2015 10:59 am | by University of Cambridge | Comments

New cost-effective material which mimics natural ‘extracellular matrix’ has allowed scientists to capture previously unseen behavior in individual plant cells, including new shapes and interactions. New methods highlight potential developments for plant tissue engineering.


Jammed Up Cellular Highways May Initiate Dementia and ALS

August 27, 2015 10:41 am | by Johns Hopkins University | Comments

Researchers say they have discovered some of the first steps in how a very common gene mutation causes the brain damage associated with both amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

Automated Speech Analysis Helps Predict Psychosis Onset

August 27, 2015 9:37 am | by Bevin Fletcher, Associate Editor | Comments

A small proof-of-principal study by researchers at Columbia University Medical Center found an automated speech analysis program was able to differentiate between at-risk young people who developed psychosis and those who did not, with 100 percent accuracy. 


Developing a New Tool to Detect a Frequently Missed Sex Chromosome Disorder in Boys

August 26, 2015 10:54 am | by Columbia University | Comments

Klinefelter syndrome is the most common disorder of the male sex chromosomes, yet is rarely diagnosed in children. A new assessment tool is being developed by researchers to help pediatricians detect the physical traits of the syndrome. The tool could pave the way for early interventions that prevent and treat a range of physical, psychological, social, and cognitive impairments.


Scientists Develop Novel Technique for Kidney Research

August 26, 2015 10:39 am | by Yale University | Comments

One in four patients treated with the widely used anti-cancer drug cisplatin develop chronic kidney disease. To better understand how the treatment leads to kidney damage, and possibly prevent it, a team of researchers developed a new 3D-imaging technique to peer deep into these vital organs.


These Microscopic Fish are 3D-printed to Do More Than Swim

August 26, 2015 10:23 am | by UC San Diego | Comments

Nanoengineers used an innovative 3D printing technology they developed to manufacture multipurpose fish-shaped microrobots -- called microfish -- that swim around efficiently in liquids, are chemically powered by hydrogen peroxide and magnetically controlled.
