  • The Art and Science of the Diagram: Communicating the Knowledge of the Heavens, the Earth and the Arcane, Final Part

    Credit: http://members.westnet.com.au/gary-david-thompson/page11-24.html

    In this final blog post of the Art and Science of the Diagram (see Part 1 and Part 2) series, I will venture away from more overt conceptual (and computational) diagrams in the practices of science to consider what it means to have all these diagrammatic models and schemas. As a refresher of what I [...]

    mating cicadas smaller

    All the hoopla over the 17-year cicadas, set to emerge any day now in the Northeast, has so far missed one of the greatest facts about them. Sure, it’s no surprise for grand gatherings of male animals to get together and sing their hearts out. Frogs do it, crickets do it, and we all know [...]

    We Fit Nature to Us: Evolution’s 2-Way Street

    Sci Am New Evo Theory Need Stool

    It is in our nature to fit nature to us. We are best at it, but other species do it. This obvious but overlooked factor contradicts the dominant one-way-street gene-centric view of adaptation. A better framework for evolution is needed. Its shape isn’t clear, but it must incorporate: extracorporeal gene effects, “gene-culture coevolution,” “niche construction,” [...]

    Prolonging the Buzz with Grandma

    Sperm and eggs fuse and divide repeatedly, eventually creating more germ cells to continue the "immortal germline."

    A nonagenarian puts aging research into perspective. “To another ninety years!” I said, toasting my grandma. My brother and I had stopped by her apartment on her birthday with a six-pack of bock beer, her favorite brewing style. Being a German Wisconsin woman, there are few things she likes better.

    Gardasil_vaccine_and_box_new

When President Nixon began the war on cancer in 1971 with the signing of the National Cancer Act, it was intended to “…strengthen the National Cancer Institute in order to more effectively carry out the national effort against cancer.” Despite the billions of dollars spent, and a [...]

    In the Facebook age, it’s increasingly clear that scientific research and innovation simply can’t be relegated to the informational vacuums or institutional silos of yore. Long before the golden era of all networks social (and even before Alan Alda had a grad program at Stony Brook in communicating science named after him), luminaries including Sagan [...]
