    The Zika epidemic began long before anyone noticed

    The Zika virus probably arrived in the Western Hemisphere from somewhere in the Pacific more than a year before it was detected, a new genetic analysis of the epidemic shows. Researchers also found that as Zika fanned outward from Brazil, it entered neighboring countries and South Florida multiple times without being noticed.

    Although Zika quietly took root in northeastern Brazil in late...

    Hybrid protein offers malaria protection

    Dogged genetic detective work has led scientists to a hybrid red blood cell protein that offers some protection against malaria.

    Reporting online May 18 in Science, researchers describe a genetic variant that apparently is responsible for the fusion of two proteins that protrude from the membranes of red blood cells. In its hybrid form, the protein somehow makes it more difficult for the...

    Jumping genes play a big role in what makes us human

    Face-to-face, a human and a chimpanzee are easy to tell apart. The two species share a common primate ancestor, but over millions of years, their characteristics have morphed into easily distinguishable features. Chimps developed prominent brow ridges, flat noses, low-crowned heads and protruding muzzles. Human noses jut from relatively flat faces under high-domed crowns.

    Those facial...

    Selfish genes hide for decades in plain sight of worm geneticists

    View the video

    A strain of wild Hawaiian worms has helped unmask long-studied genes as just plain selfish. The scammers beat the usual odds of inheritance and spread extra fast by making mother worms poison some of their offspring.

    Biologists have for decades discussed how two genes in the familiar lab nematode Caenorhabditis elegans might help embryos build their organs. Working...

    Breast cancer cells spread in an already-armed mob

    COLD SPRING HARBOR, N.Y. — When breast cancer spreads, it moves in gangs of ready-to-rumble tumor cells, a small genetic study suggests. Most of the mutations that drive recurrent tumors when they pop up elsewhere in the body were present in the original tumor, geneticist Elaine Mardis reported May 9 at the Biology of Genomes meeting.

    For many types of cancer, it is the spread, or...

    Fox experiment is replaying domestication in fast-forward

    How to Tame a Fox (and Build a Dog)Lee Alan Dugatkinand Lyudmila TrutUniv. of Chicago, $26

    In 1959, Lyudmila Trut rode trains through Siberia to visit fox farms. She wasn’t looking for furs. She needed a farm to host an audacious experiment dreamed up by geneticist Dmitry Belyaev: to create a domestic animal as docile as a dog from aggressive, wily silver foxes.

    Evolutionary...

    Ancient DNA bucks tale of how the horse was tamed

    DNA from 2,000-year-old stallions is helping rewrite the story of horse domestication.

    Ancient domesticated horses had much more genetic diversity than their present-day descendants do, researchers report in the April 28 Science. In particular, these ancient horses had many more varieties of Y chromosomes and fewer harmful mutations than horses do now. Previous studies based on the...

    Dog DNA study maps breeds across the world

    Mapping the relationships between different dog breeds is rough (get it?), but a team of scientists at the National Institutes of Health did just that using the DNA of 1,346 dogs from 161 breeds. Their analysis, which appears April 25 in Cell Reports, offers a lot to chew on.

    Here are five key findings from the work:

    Dogs were bred for specific jobs, and this shows in their genes.

    Gene knockouts in people provide drug safety, effectiveness clues

    Some Pakistani people are real knockouts, a new DNA study finds. Knockouts in this sense doesn’t refer to boxing or a stunning appearance, but to natural mutations that inactivate, or “knock out” certain genes. The study suggests that human knockouts could prove valuable evidence for understanding how genes work and for developing drugs.

    Among 10,503 adults participating in a heart...

    Genetic risk of getting second cancer tallied for pediatric survivors

    WASHINGTON — A second cancer later in life is common for childhood cancer survivors, and scientists now have a sense of the role genes play when this happens. A project that mined the genetic data of a group of survivors finds that 11.5 percent carry mutations that increase the risk of a subsequent cancer.

    “We’ve always known that among survivors, a certain population will experience...
