Détente, and a good fence, can be far more effective than all-out assault in the age-old war between man and microbe, University of Chicago researchers report in the February issue of Gastroenterology. By injecting a protective coating into the intestines to pacify bacteria there instead of relying on antibiotics to kill them, the scientists were able to protect mice from otherwise lethal infections.
The protective coating, a high-molecular-weight polyethylene glycol, protected mice who had had major surgery from infection with Pseudomonas aeruginosa, a virulent pathogen that quickly kills 100 percent of untreated mice. A Pseudomonas infection is one of the most lethal complications for patients after major surgery.
"If you cant beat them -- and you cant -- then you want to indulge them," says John Alverdy, M.D., associate professor of surgery at the University of Chicago and director of the study. "An unhappy parasite is programmed to kill the host and move on. So we decided to look for ways to gratify them, to please these powerful microbes and keep them content."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
