One of the great frustrations of modern medicine is the creeping ability of pathogenic microbes to develop resistance to the antibiotics we throw at them.
More and more, microbes are able to eliminate, modify and sequester the toxic molecules that make up the arsenal of antibiotics that humans use to treat infection, making once-miraculous drugs increasingly impotent. Now, adding to the mix of devices dangerous microbes deploy to evade destruction by antibiotics, scientists have discovered another way pathogens escape from the most potent drugs: self-sacrifice.
It is the equivalent of the courageous soldier throwing himself on a grenade, says Jon S. Thorson, a University of Wisconsin-Madison professor of pharmacy and the senior author of a paper describing the newfound method of antibiotic resistance published in this weeks (Sept. 12) edition of the journal Science.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
