Researchers have crafted a gene circuit that permits precise tuning of a gene's expression in a cell, an advance that should allow for more accurate analysis of the gene's role...
How Stem Cells Develop Into Blood Cells
How messages sent within stem cells through a specific communication pathway can trigger the cells to specialize and become blood cells in humans has been discovered by scientists of the...
Satellite spies on tree-eating bugs
More than 150 years after a small Eurasian tree named tamarisk or saltcedar started taking over river banks throughout the U.S. Southwest, saltcedar leaf beetles were unleashed to defoliate the...
Small molecules block cancer gene
Finding molecules that block the activity of the oncogene Stat 3 (signal transducer and activator of transcription) required screening literally millions of compounds, using computers that compared the structure of...
