Origins of DNA folding suggested in archaea
In the cells of palm trees, humans, and some single-celled microorganisms, DNA gets bent the same way. Now, by studying the 3-D structure of proteins bound to DNA in microbes called Archaea, University of Colorado Boulder ...

How the African striped mouse got its stripes
A gene called Alx3 blocks the differentiation of pigment-producing cells in the skin of the African striped mouse, thus generating the mouse's characteristic light-colored stripes, a new study shows. The same gene also determines ...

Researchers identify new factors that guide organization of plant roots
As the root of a growing plant pushes its way through soil, its cells have a lot of organizing to do. New cells must take on the appropriate identities and positions to form distinct layers of tissue that give the root its ...

Technique takes cues from astronomy and ophthalmology to sharpen microscope images
The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the ...
