What’s the new story on fruit flies?
CALTECH (US)—For decades, science texts have told a simple and straightforward story about a particular protein—a transcription factor—that helps the embryo of the fruit fly, Drosophila melanogaster, pattern tissues in a manner that depends on the levels of this factor within individual cells. (more…)

Hope for newborns found in heart’s early beginning
CORNELL (US)—Congenital heart defects are the most common malformations in newborns born in the United States, and in most cases, scientists don’t know why the defects occur. Treatment options, including valve replacement surgery, come with a host of drawbacks for tiny infants. Jonathan Butcher, assistant professor of biomedical engineering at Cornell University, studies embryonic heart valve development from the very beginning of the process with hopes that a greater understanding will lead to new treatments.
