Study of U.S. Travelers to Mexico and Guatemala Found 65 Percent Prevalence Rate
A majority of traveler’s diarrhea cases among U.S. travelers to Mexico and Guatemala were attributed to Norovirus, a common cause of nonbacterial gastroenteritis outbreaks usually associated with developed countries, according to a new study by researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions. The researchers also found that the longer travelers stayed at their destination, the more likely they were to contract Norovirus infections. The study is published in the March 2005 issue of the Journal of Clinical Microbiology.
"Noroviruses are known to be a major cause of food and waterborne gastronteritis outbreaks in domestic and unique settings, such as cruise ships, and also have been documented among military groups during deployment overseas. However, few studies have investigated the prevalence of Norovirus infection among civilians traveling from industrialized to developing countries,” said Kellogg J. Schwab, PhD, corresponding author of the study and an assistant professor in the Department of Environmental Health Sciences at the Johns Hopkins Bloomberg School of Public Health.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
