Astronomers Create 3D Map of Dark Matter (SPACE.com)
   SPACE.com - SEATTLE - Astronomers have mapped the positions of vast, invisible isles of dark matter in the sky, within which normal "bright" matter galaxies are embedded like glittering gems. The three-dimensional map [image] spans not only space, but also time, and stretches back to when the universe was only about half its present age.

Dr. Anthony Atala, head of Wake Forest's regenerative medicine institute,  is photographed in his research lab at Piedmont Triad Research Park in Winston-Salem, NC, Friday, Jan. 5, 2007.  Scientists reported Sunday they had found a plentiful source of stem cells in the fluid that cushions babies in the womb and produced a variety of tissue types from these cells _ sidestepping the controversy over destroying embryos for research.   Researchers at Wake Forest University and Harvard University reported the stem cells they drew from amniotic fluid donated by pregnant women hold much the same promise as embryonic stem cells.

Rapid, Low-Cost DNA Testing

Rapid, Low-Cost DNA Testing
   University of Rochester Professor Lewis Rothberg received a NYSTAR grant to continue working on a recent discovery by his group: how to rapidly test DNA to improve our health and make sure we're drinking clean water and eating uncontaminated food. Rothberg's new method can help forensics labs identify criminals, test water, and identify harmful genetic sequences in medical research. Rothberg's innovative procedure quickly and inexpensively identifies genetic sequences in any sample of DNA.
