In a national study of children in motor vehicle crashes, researchers at The Childrens Hospital of Philadelphia report that traumatic stress can occur without injury. Looking at a wide range of crashes reported to State Farm Insurance Companies®, researchers found that while most children did well, two percent of the children and five percent of their parents experienced multiple traumatic stress symptoms that disrupted their lives.
There are more than 1.5 million crashes involving children in the U.S. annually, suggesting that more than 25,000 children each year may require help in coping with reactions to a crash. Researchers urge clinicians to screen children and their parents after any crash experience.
"Until now, research on traumatic stress after crashes had only examined patient populations in hospitals or clinics," said Dr. Flaura Winston, M.D., Ph.D., a pediatrician at The Childrens Hospital of Philadelphia and lead author on the study. "In this study, we found that, although its less common, traumatic stress can occur in children and their parents even if a child wasnt injured in the crash." Dr Winston is also co-Director and a principal investigator on the Partners for Child Passenger Safety study.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
