    How they shine

    Believe it or not, science has barely begun to fathom the peacock’s tail. Subtle as a pink tuxedo, one might think. Big flashy thing. Peahens love it. What’s not to understand.

    Roslyn Dakin, though, has plenty of questions. There’s the matter of choreography. Already this year she has left Queen’s University in Kingston, Canada, to visit peacocks (the birds) in Los Angeles...

    When Worlds Collide

    Science fiction movies and books are full of parallel universes.

    In a typical scenario, as in the movie Sliding Doors, something happens in one universe—like a woman misses a train—but in a parallel universe, the same woman catches it, setting in motion diverging life paths.

    Insects (the original white meat)

    You bite into a piece of candy and find a cricket leg. Eewwww. Or notice that raisin in a bowl of cereal has legs and wings. Bam, down the disposal it goes. Such filth in foods is supposedly illegal, but the Food and Drug Administration’s actual tolerance is far from zero. FDA rules allow up to 60 insect fragments on average in a composite of six 100-gram chocolate samples. For peanut butter...

    Reviving extinct DNA

    Tasmanian tigers are back. Sort of. A small bit of the extinct marsupial’s DNA is alive and well in the cells of some genetically engineered mice.

    Scientists have produced proteins from mammoth and Neandertal genes in cells, but the new study, appearing in the May 19 PLoS ONE, is the first to examine the activity of an extinct piece of DNA in a whole animal....
