DNA origami rectangle made with 'bottom-up' construction approach

The construction of complex man-made objects--a car, for example, or even a pizza--almost invariably entails what are known as "top-down" processes, in which the structure and order of the thing being built is imposed from the outside (say, by an automobile assembly line, or the hands of the pizza maker).

Discovery of marker for colon stem cells could shed light on tumor growth

Cancer researchers led by Bruce Boman, M.D., Ph.D. director of Cancer Genetics and Stem Cell Biology at the Helen F. Graham Cancer Center of the Christiana Care Health System, and a faculty member at the University of Delaware, have discovered an enzyme common to both normal and malignant colon stem cells that will assist scientists searching for a cure for colon cancer.

Antibiotics could treat cystic fibrosis, other genetic diseases

By modifying the properties of the common antibiotic gentamicin, researchers at the Technion-Israel Institute of Technology have developed what could become an effective treatment for many human genetic diseases, including cystic fibrosis (CF), Duchenne muscular dystrophy, Usher Syndrome and numerous cancers.
