Each year, nearly 500,000 Americans are admitted to hospitals for staph infections. Research shows that more than 50 percent of those are from methicillin-resistant S. aureus, or MRSA, which is resistant to current antibiotics.
Boise State biology scientists created a vaccine that uses a cholera toxin molecule called A2/B chimera, which also contains an iron-regulated surface determinant from S. aureus, that was given to mice through the nose. The researchers believed that these stable chimeric molecules with unique binding properties would provide immunity to staph infections. The results supported this theory and showed that the new vaccine could induce significant immunity to staph in mice when delivered through the nose.
The results appear online in the journal Clinical and Vaccine Immunology.
“We knew that a successful vaccine against staph would have to contain a combination of antigens,” study co-author Juliette Tinker, assistant professor of biological sciences at Boise State. “Staph is a very complex bacteria that has a lot of proteins on the surface that change frequently, so we picked one that seemed to be present in many of the strains of staph. We knew only incorporating one or two proteins into a vaccine wasn’t enough, we needed many.”
Tinker and her research team studied the immune response in 24 mice that were given the vaccine they created and measured how many antibodies the mice produced against staph over 45 days. The results showed the mice had a significant number of antibodies against staph, although a booster dose was needed after the 10th day.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
