Agilent Technologies Introduces First Commercial Mouse Microarray for Comparative Genomic Hybridization Research

Tuberculosis remains a major global health threat. Although more than 3 billion doses of the BCG vaccine have been administered to fight tuberculosis, the ability of the BCG vaccine to protect adults is very limited, as is its efficacy against newly emerging isolates. . In a study appearing online on August 18 in advance of print publication of the September 1 issue of the Journal of Clinical Inv...

Divergent mating systems and parental conflict as a barrier to hybridization in flowering plants

Sexual reproduction can be thought of as a cooperative process in which two individuals come together to produce a new individual. It can also be viewed as a process in which two parties with differing interests, investment, and background interact to produce a new individual. From the former perspective, parental interests are unified (both wish to produce vigorous offspring), while the latter s...

Ring-like formations in drying DNA drops could affect hybridization studies

Coffee drinkers are familiar with the ring-shaped stains that result from spilled drops that have dried, in which the brown stain is not evenly distributed, but instead concentrated at the edge. Now, a team led by Gerard Wong, a professor of materials science and engineering, physics, and bioengineering at the University of Illinois at Urbana-Champaign has found the same "coffee-ring" formation i...

Study provides new understanding of spontaneous hybridization

Plant and animal breeders have long used hybridization to transfer useful traits between species. But does the same process happen without human aid? In a new study in the June issue of American Naturalist, Kenneth D. Whitney (Indiana University and Rice University), Rebecca A. Randell (Indiana University), and Loren H. Rieseberg (Indiana University), explore how spontaneous hybridization ?known...
