Spanish researchers have discovered a key component of infectious bacteria's battle plan, identifying a protein that tells bacteria in a colony to halt their forward march when antibiotics are present, waiting until the coast is clear before resuming the infection. The finding shows how bacteria outmaneuver antibiotics in the body to continue infecting an organ even after treatment, but it also pinpoints a vulnerability that researchers may be able to exploit to make antibiotics more effective.
When it comes to burns and other exterior flesh wounds, bacteria often show no quarter, getting in deep and causing serious complications for patients unlucky enough to be stricken with infections. But a new technique takes a page from the book of guerrilla warfare, lacing wound dressings with antibacterial land mines that coax malicious microbes into spelling their own dooms.
As Space Shuttle Discovery lifted off this morning -- setting a record for the most women simultaneously in space -- three other women on the ground looked to break some ground of their own. An Arizona State U. Biodesign Institute research trio launched a first-of-its-kind experiment aboard Discovery that will offer insight into how cells react to infectious disease under the low-gravity conditions of space.
