Tentacles test tenets of evolution
Elie Dolgin | Nov 17, 2008 | 3 min read
Novel genes, rather than regulatory DNA, underlie the evolution of morphological traits, according to research published today (Nov. 17) in __PLoS Biology__. The new linkurl:study;http://biology.plosjournals.org/perlserv/?request=get-document&doi=10.1371/journal.pbio.0060278 reports that genes found in simple freshwater animals -- but not in any other evolutionary lineage -- can drive changes in body plan, and stokes the flames of a long-standing debate among evolutionary developmental biologist

Lasker Awards Target Developmental, Diagnostic Genetics
Rebecca Andrews | Sep 29, 1991 | 6 min read
The Laskers are among the most prestigious medical research awards in the world and among the oldest in the United States. Since they were first presented in 1944, 49 winners have gone on to win Nobel Prizes. Jordan Gutterman of the M.D. Anderson Cancer Center in Houston, executive vice president of the Albert and Mary Lasker Foundation, and director of the awards program since earlier this year, attributes the prestige of the awards to their longevity and to the "extraordinary quality&quo
