  • Genetics of the body snatchers!
    Genetics of the body snatchers!

    athogens can change the behavior of their hosts — and now we see that a single viral gene forces a caterpillar to climb a tree before it dies. From that high vantage, the virus can infect more caterpillars. It’s nifty and thrifty, unless you’re a gypsy moth!

  • Enter the realm of the ants
    Enter the realm of the ants

    In many environments, ants know the tricks of survival, even domination. Skeptical? Ask the fire ant. Ask the army ant. A series of studies is revealing the genetic basis for survival and domination. What genes are active, and which have disappeared after prolonged unemployment?

  • Genetic solution to cancer, diabetes?
    Genetic solution to cancer, diabetes?

    People with a genetic case of dwarfism in Ecuador don’t get cancer or diabetes, and a new study links that benefit to the genetic changes we see when calories are severely restricted. Could blocking growth hormone in adulthood lead to serious health benefits?

  • Untangling cancer’s genetic trajectory
    Untangling cancer’s genetic trajectory

    Until now, getting a picture of genetic change in a tumor over time has been next to impossible. A new study reveals that cancer’s genetic tangle gets more complicated with time.

  • Genetic tests go mainstream
    Genetic tests go mainstream

    Companies are marketing genetic tests direct to consumers. Some tests can be lifesavers. But many tests return confusing results, which even doctors have a hard time interpreting.

  • Celebrating Darwin and evolution
    Celebrating Darwin and evolution

    The theory of evolution is 150 years old, but forever young. We examine proofs for evolution, and four cool studies showing just how correct Charles Darwin was. Want to talk about silent crickets?

  • “Store that fat” says new gene. Is obesity explained?

    New discovery shows how all animals store fat in cells, could lead to advances in fight against obesity or diabetes. Funny, maybe storing fat is a good thing.

  • Nobel goes to gene-knockouts

    A technology that revolutionized medicine and genetics gets the big Nobelian Nod. Cancer. Heart disease. Obesity. Research into virtually every major disease has gotten a boost from the Knockout Nobel!

  • Study finds key to colony-collapse disorder

    Fast genomic analysis could open the door to breakthroughs in health, ecology and genetics. How do these machines work, and what have they taught about obesity, microbial diversity, and drug treatment?

  • Ants: My Family, Right or Wrong!

    The Argentine ant invaded California 100 years ago, forming “super-colonies” that stretch hundreds of miles. Most ants attack nearby nests. Why have Argentine ants declared peace with neighbors?
