Team finds an economical way to boost the vitamin A content of maize (1/21/2008)

A team of plant geneticists and crop scientists has pioneered an economical approach to the selective breeding of maize that can boost levels of provitamin A, the precursors that are converted to vitamin A upon consumption. This innovation could help to enhance the nutritional status of millions of people in the developing world. ...> Full Article

Mechanics of gene transcription (1/9/2008)

The molecular machinery behind gene transcription -- the intricate transfer of information from a segment of DNA to a corresponding strand of messenger RNA -- isn't stationed in special "transcription factories" within a cell nucleus, according to Cornell researchers. Instead, the enzyme RNA polymerase II (Pol II) and other key molecules can assemble at the site of an activated gene, regardless of the gene's position. ...> Full Article
