Needling chromosomes yields insights into cell division
...n chromosome duplication. "So, we're left with the mystery of what molecules hold the chromatids together at this point in cell division," Nicklas said. "But that's the usual outcome of work in my laboratory and a sign that we're doing good science since we raise new questions. We lay the mechanistic groundw...Discovery of first demethylase molecule, a long-sought gene regulator
...had exhausted the likely possibilities for how the mystery protein worked to suppress gene activity, so one day he tried an unlikely experiment. He had the purified protein in a test tube and decided to feed it methylated histones. His finding, that the enzyme could efficiently chew off the methyl group, lea...Study in Royal Society journal on first evidence for magnetic field detection in sharks
...ts that benefit others evolve has been a perennial mystery for evolutionary biology. We chose antibiotic resistance as a test case for looking at the evolution of group-beneficial traits. We constructed strains of bacteria that secrete an enzyme into their environment that breaks down the antibiotic ampicill...Rob DeSalle and Michael Yudell to appear at the American Museum of Natural History

Unraveling the often-misunderstood mystery of the genome and how it can better our lives, Dr. DeSalle and Mr. Yudell will discuss such controversial and vital topics as: Personalized Medicine Race and Genetics Genetically Modified Food Evolution and Genetics Ethical and Policy Chal...Salt-water minnow research helps explain human cardiology
...nd a genetic set of keys that begins to unlock the mystery of why certain people can eat fatty foods and not suffer from heart disease, and why some medical treatments work more effectively in some people than in others," said Philip Taylor, director of NSF's biological oceanography program.

We need to know more about the cognitive processes involved in egg recognition and rejection by the coots," Lyon said.
