See-through zebrafish, new imaging method put blood stem cells in high-resolution spotlight

MADISON — For the first time, researchers can get a high-resolution view of single blood stem cells thanks to a little help from microscopy and zebrafish.Researchers at the University of Wisconsin–Madison and the University of California San Diego have developed a method for scientists to track a single blood stem cell in a live organism and then describe the ultrastructure, or architecture, of that same cell using electron microscopy.

Researcher gets National Science Foundation grant to study hidden messages in digital images

For more than 25 years, Binghamton University’s Jessica Fridrich has studied digital-image steganography — the science of hiding messages inside ordinary-looking photos. Just as technology has evolved and become more sophisticated, so have the methods to share secrets — and a recent $768,964 grant from the National Science Foundation will help Fridrich stay ahead of the curve.
