People could be exposed to antibiotic-resistant bacteria from breathing the air from concentrated swine feeding facilities, according to researchers at the Johns Hopkins Bloomberg School of Public Health. They detected bacteria resistant to at least two antibiotics in air samples collected from inside a large-scale swine operation in the Mid-Atlantic region of the United States. Until now, little research has been conducted regarding the presence of antibiotic-resistant bacteria in the air within industrial swine facilities. The study adds to the understanding of various pathways in which humans can be exposed to antibiotic-resistant bacteria, such as consumption of retail pork products and contact with or ingestion of soil, surface water and groundwater near production operations. The article is published in the online edition of Environmental Health Perspectives.
“Eating retail pork products is not the only pathway of exposure for the transfer of antibiotic-resistant bacteria from swine to humans. Environmental pathways may be equally important,” said Amy Chapin, the study’s lead author and a doctoral candidate at the Bloomberg School of Public Health’s Department of Environmental Health Sciences.
Chapin explained that the use of antibiotics in industrial animal production has a significant impact on the emergence of antibiotic-resistant bacteria that threaten human health. Using antibiotics in animals can decrease the effectiveness of the same antibiotics used to combat human infections. The non-therapeutic use of antimicrobials in livestock production in the United States comprises an estimated 60 to 80 percent of the total antimicrobial production nationally. Nontherapeutic doses of drugs are given to swine to promote growth and improve feed efficiency - not to treat actual swine disease.

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,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
