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.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
