UD professors study microbes as potential biomarkers for damaged concrete
Concrete is the most widely used construction material in the world. However, many concrete roadways and bridges crack due to internal chemical reactions, temperature fluctuations or external chemical and physical stresses.
One internal chemical reaction is the Alkali-Silica Reaction (ASR) that destroys the concrete from within. (more…)
ANN ARBOR, Mich.— Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study from an international research team.
The study is the first comprehensive effort to directly compare the impacts of biological diversity loss to the anticipated effects of a host of other human-caused environmental changes.
The results highlight the need for stronger local, national and international efforts to protect biodiversity and the benefits it provides, according to the researchers, who are based at nine institutions in the United States, Canada and Sweden. (more…)
*In a newly published study, researchers found the majority of medical residents surveyed experienced a decline in empathy over the course of the oft-used “long-call” shift.*
Fatigue and sleep deprivation are undisputed job descriptors for medical residents, but results from a new study indicate the common “long-call” shift may have adverse effects not only for residents, but also their patients.
University of Arizona alumna Stacey Passalacqua, now a visiting assistant professor at James Madison University’s School of Communication, surveyed nearly 100 medical residents at several different hospitals. (more…)
