    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.

    Or, as in Isaac Asimov’s imaginative novel The Gods Themselves, alien inhabitants of a...

    Audubon’s insect cafeteria

    Read the main feature story on insects here.

    Would you fancy grasshopper gumbo? Perhaps mushroom hors d’oeuvres topped with a batter-dipped and lightly fried dragonfly—in season, of course—drizzled with a sauce of Dijon mustard, soy and butter? These are among recipes that self-taught insect chef Zack Lemann has whipped up as possible menu items for Bug Appétit. This restaurant...

    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....

    ISEF winners announced

    ATLANTA— More than 1,500 young scientists from 51 countries, regions and territories flexed their mental muscles in Atlanta May 12–16 at an event of Olympic proportions. Three students took home the gold.

    All together, $4 million in scholarships, tuition grants and scientific trips and equipment were at stake at the Intel International Science and Engineering Fair, the world's...

    Phlegmatic molecules

    Chemists can now watch the structures of molecules as they change shape, much like shooting multiple frames of a galloping horse. The new view reveals that when certain molecules switch between different conformations, they do so less often than expected — a finding that could require chemists to revise their theories and that could lead to a better understanding of processes such as how...

    Climate clues in ice

    A kilometers-long ice core from Antarctica has recorded climate information for the past 800,000 years and has revealed a three millennia–long period when carbon dioxide levels in the air were lower than any previously measured.

    The longest detailed records of atmospheric gases previously reported, from the uppermost sections of a 3.2 kilometer–long ice core...

    A shifty moon

    Imagine a shift in the position of Earth’s continents so extreme that Alaska would move to the equator. Astronomers have now found evidence that such a shift actually happened on Jupiter’s large icy moon Europa. The sliding of the moon’s icy surface provides further evidence that an ocean lies beneath the ice, upping the odds that Europa has a subterranean habitat that could support some kind...

    Identifying viable embryos

    Australian researchers have taken fingerprinting children to the next level. A group at MonashUniversity in Melbourne is using DNA fingerprinting and other molecular techniques to identify viable embryos created during fertility procedures.

    Such research could improve the chance a woman will get pregnant when only one embryo is transferred to the womb. Currently, many...
