Source of cancer stem cells' resistance to radiation discovered

Much to the dismay of patients and physicians, cancer stem cells - tiny powerhouses that generate and maintain tumor growth in many types of cancers - are relatively resistant to the ionizing radiation often used as therapy for these conditions.

Super-fine oil-and-water emulsion protects against superbugs that kill cystic fibrosis patients

University of Michigan scientists report highly encouraging evidence that a super-fine oil-and-water emulsion, already shown to kill many other microbes, may be able to quell the ravaging, often drug-resistant infections that cause nearly all cystic fibrosis deaths.
