Alcohol-exposed babies respond more slowly to their environment, and take longer to calm down
Most of the research on arousal and attention deficits caused by prenatal alcohol exposure has been conducted with children. An innovative new study, published in the March issue of Alcoholism: Clinical & Experimental Research, examines different components of attention through use of heart-rate data collected from six-month-old infants whose mothers drank during pregnancy. The findings indicate that slower processing speeds and arousal-regulation problems exist as early as infancy.
"The postnatal environment that children experience has a tremendous impact on childrens cognitive status and attentional regulation skills," explained Julie A. Kable, assistant professor at Emory University School of Medicine and first author of the study. "Children of women who consume large amounts of alcohol during pregnancy and/or are substance abusers often experience family environments that do not support optimal development. As a result, when you examine older children it is often difficult to partition out the impact of the prenatal exposure with the impact of the postnatal environment. Assessments conducted closer in time to the insult provide a more accurate picture of the teratogenic effect."

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
