    Maps show genetic diversity in mammals, amphibians around the world

    View the slideshow

    Maps have long been used to show the animal kingdom’s range, regional mix, populations at risk and more. Now a new set of maps reveals the global distribution of genetic diversity.

    “Without genetic diversity, species can’t evolve into new species,” says Andreia Miraldo, a population geneticist at the Natural History Museum of Denmark in Copenhagen. “It...

  • Staph infections still a concern

    New hope for control of staph infections

    Staphylococcal infections — especially rampant in hospitals and responsible for … some fatal disorders — may be virtually stamped out. Researchers … have extracted teichoic acid from the bacteria’s cell wall and used it to protect groups of mice from subsequent massive doses of virulent staph organisms. — Science News, October 29, 1966

    2016 Nobels: Science News fans read it here first

    This year’s Nobel Prizes honored scientific achievements that dedicated Science News readers (with good memories) would have found familiar. A dive into our archives revealed some interesting results.

    The physiology or medicine prize recognized autophagy, the cellular process by which living cells dispose of — or recycle — their biochemical garbage. Molecular biology writer Tina...

    Readers question the biology of alcoholism and more

    Gene and tonic

    Lab rats bred to drink a lot or hardly at all have revealed 930 genes linked to a preference for alcohol, a recent study shows. Tina Hesman Saey reported the findings in “Rats offer DNA clues to a­lcoholism” (SN: 9/3/16, p. 8).

    John M. Wozniak Jr. wondered if the drinking rats were truly alcoholic, or if they gained nutritional or energy b­enefits from the alcohol....

    Big biological datasets map life's networks

    Michael Snyder’s genes were telling him that he might be at increased risk for type 2 diabetes. The Stanford University geneticist wasn’t worried: He felt healthy and didn’t have a family history of the disease. But as he monitored other aspects of his own biological data over months and years, he saw that diabetes was indeed emerging, even though he showed no symptoms.

    Snyder’s story...
