A novel method, developed by an economist at the Tepper School of Business at Carnegie Mellon University, has been created to evaluate a worker's skillset and determine its impact on wages.
A study of an unusual snapping turtle with one lung found shared characteristics with humans born with one lung who survive beyond infancy. Digital 3-D anatomical models created by Emma Schachner, PhD, Assistant Professor of Cell Biology & Anatomy at LSU Health New Orleans School of Medicine, made the detailed research possible.
If you've ever tapped a screen to send a tweet, opted for a glass bottled soda because of taste, or drooled over art glass in a gallery, then your life has been changed for the better by the transparent yet durable combination of sand and simple chemicals we call glass. Reactions visited McFadden Art Glass in Baltimore, Maryland, to learn about the chemistry of this ancient material.
Physicists at MIT have designed a pocket-sized cosmic ray muon detector to track these ghostly particles. The detector can be made with common electrical parts, and when turned on, it lights up and counts each time a muon passes through. The relatively simple device costs just $100 to build, making it the most affordable muon detector available today.
Researchers at Portland State University are learning more about undergraduates' experience in science, technology, engineering and math (STEM) classes and sharing a set of survey questions that will help researchers and educators at other universities do the same. This survey was developed by a team of researchers in PSU's STEM Equity and Education Institute with the help of instructors in chemistry, biology and physics.
Bystander cardiopulmonary resuscitation (CPR) is known to improve survival of cardiac arrest; however, there is a disparate geographic variation in cardiac arrest survival and only a small number of the US population is trained in CPR annually. A review published in the Journal of the American College of Cardiology found that over half of US states require some form of CPR training in high school, but there is wide variability in instruction.
By six to nine months, babies already have a basic understanding of words for food and body parts. In a new report, Duke University researchers show that babies also recognize that words like 'car' and 'stroller' are more alike than 'car' and 'juice.' By analyzing home recordings, the team found that overall, babies' word knowledge correlated with the proportion of time they heard people talking about objects in their immediate surroundings.
Childhood obesity is often attributed to a lack of exercise. So what about sports among elementary school students? A team from the Technical University of Munich pursued this question and collected the results of fitness tests for first-year students over a period of one decade. Their study shows that students did not lose their strength. Speed or balance even increased over the time of 10 years. One change was in the boys, whose endurance decreased compared to the girls of the same age.
While simulation platforms have been used to train surgeons before they enter an actual operating room (OR), few studies have evaluated how well trainees transfer those skills from the simulator to the OR. Now, a study led by Rensselaer Polytechnic Institute that used noninvasive brain imaging to evaluate brain activity has found that simulator-trained medical students successfully transferred those skills to operating on cadavers and were faster than peers who had no simulator training.
Given the critical role livestock play in Mongolia, transmission of tick-borne diseases can have very real health and economic implications for livestock and herders. George Mason University's Dr. Michael von Fricken and colleagues explored the interaction between nomadic herders, the livestock they own, and the tick-borne diseases they are exposed to.
