New UCLA research published in Nature may lead to an effective alternative to antibiotic drugs for treating bacterial diseases.
UCLA microbiologists report the discovery of a new class of genetic elements, similar to retroviruses, that operate in bacteria, allowing them to diversify their proteins to bind to a large variety of receptors. The team discovered this fundamental mechanism in the most abundant life?forms on Earth: bacteriophages, the viruses that infect bacteria.
"A problem with antibiotics is that bacteria can mutate and become resistant to a particular antibiotic, while the antibiotic is static and cannot change," said Jeffery F. Miller, professor and chair of microbiology, immunology and molecular genetics at UCLA, who holds UCLAs M. Philip Davis Chair in Microbiology and Immunology, and who led the research team. "Bacteriophages ("phages") are natures anti-microbials, and they are amazingly dynamic. If the bacterium mutates in an effort to evade, the bacteriophage can change its specificity using the mechanism we discovered, to kill the newly resistant bacterium."

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
