Parkinson's in a dish: Researchers reproduce brain oscillations

Science Daily - Wed, 03/05/2017 - 5:43pm
Abnormal oscillations in neurons that control movement, which likely cause the tremors that characterize Parkinson's disease, have long been reported in patients with the disease. Now, researchers working with stem cells report that they have reproduced these oscillations in a petri dish, paving the way for much faster ways to screen for new treatments or even a cure for Parkinson's disease.

New catalyst for water splitting developed

Science Daily - Wed, 03/05/2017 - 5:23pm
Water-splitting systems require a very efficient catalyst to speed up the chemical reaction that splits water into hydrogen and oxygen, while preventing the gases from recombining back into water. Now an international research team has developed a new catalyst with a molybdenum coating that prevents this problematic back reaction and works well in realistic operating conditions.

In children with severe heart defect, more brain abnormalities appear as staged surgeries progress

Science Daily - Wed, 03/05/2017 - 5:23pm
As children with single-ventricle disease, a complex and severe heart defect, undergo a series of three reconstructive surgeries, pediatric researchers have detected higher rates of brain abnormalities at each stage. The scientists also found associated changes in the infants’ cerebral blood flow that could offer important clues to improving long-term neurological outcomes in these children.

Research team finds no adverse risk to use of common antimalarials in first trimester of pregnancy

Science Daily - Wed, 03/05/2017 - 5:22pm
The most comprehensive international analysis on artemisinin combination antimalarials safety in pregnancy has now been released by researchers. Malaria is more common and severe in pregnant women, increasing their risk of miscarriage and other adverse outcomes. Now an international collaboration released the largest meta-analysis of all observational studies-to-date showing there was no difference in the risk of miscarriage, still births or major birth defects associated with the use of artemisinins anytime during the first trimester, compared with quinine.

First clear-cut risk genes for Tourette disorder revealed

Science Daily - Wed, 03/05/2017 - 5:19pm
Tourette disorder afflicts as many as one person in a hundred worldwide with potentially disabling symptoms including involuntary motor and vocal tics. However, researchers have so far failed to determine the cause of the disorder, and treatments have only limited effectiveness, in part because the genetics underlying the disorder have remained largely a mystery.

Spotted skunk evolution driven by climate change, suggest researchers

Science Daily - Wed, 03/05/2017 - 5:19pm
Climate plays a key role in determining what animals can live where. And while human-induced climate change has been causing major problems for wildlife as of late, changes in the Earth's climate have impacted evolution for millions of years -- offering tantalizing clues into how to protect animals facing climate change today. In a new paper, scientists have delved into the effects of Ice Age climate change upon the evolution of tiny, hand-standing skunks.

How migrations and other population dynamics could have shaped early human culture

Science Daily - Wed, 03/05/2017 - 5:19pm
Bursts of cultural advance are usually assumed to result from climate or biological changes. A new theory digs into how humans innovate, and suggests such bursts could be the result of population dynamics and culture itself.

Scientists turn human induced pluripotent stem cells into lung cells

Science Daily - Wed, 03/05/2017 - 5:19pm
Scientists have announced two major findings that further our understanding of how stem cells become organs: the ability to grow and purify the earliest lung progenitors that emerge from human stem cells, and the ability to differentiate these cells into tiny 'bronchospheres' that model cystic fibrosis. Researchers hope the results will lead to new, 'personalized medicine' approaches to treating lung disease.
