As science gets wiser, so do the bugs. The rates of drug-resistant bacteria infecting patients in the community and in the hospital have been increasing steadily in recent years, according to two new studies in the June 15 issue of Clinical Infectious Diseases, now available online.
Drug resistance in microorganisms has become a problem due in part to inappropriate prescribing and overuse of antibiotics. These drug-resistant “superbugs” can infect people and cause health problems that are difficult to address with the standard antibiotic regimens. One of the culprits is methicillin-resistant Staphylococcus aureus, or MRSA, an organism that was associated mainly with hospital-acquired infections, but is becoming increasingly common in the general community, as has been reported recently in the medical literature. It can cause problems ranging from skin infections to severe bloodstream infections and even death.
Researchers at the Baylor College of Medicine and Texas Children’s Hospital conducted a three-year study of S. aureus infections in children. They found that among S. aureus isolates acquired in the community, the proportion of isolates that were MRSA had reached 76 percent in 2003. Over the preceding three years, the number of MRSA infections acquired in the community had more than doubled. The MRSA isolates caused skin and soft tissue infections in most cases, and more than 60 percent of these children were admitted to the hospital.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
