    ‘The Poisoned City’ chronicles Flint’s water crisis

    The Poisoned CityAnna ClarkMetropolitan Books, $30

    America is built on lead. Networks of aging pipes made from the bluish-gray metal bring water into millions of U.S. homes. But when lead, a poison to the nervous system, gets into drinking water — as happened in Flint, Mich. — the heavy metal can cause irreparable harm (SN: 3/19/16, p. 8). In The Poisoned City, journalist Anna Clark...

    The brain may clean out Alzheimer’s plaques during sleep

    Neuroscientist Barbara Bendlin studies the brain as Alzheimer’s disease develops. When she goes home, she tries to leave her work in the lab. But one recent research project has crossed into her personal life: She now takes sleep much more seriously.

    Bendlin works at the University of Wisconsin–Madison, home to the Wisconsin Registry for Alzheimer’s Prevention, a study of more than 1,500...

    First global maps of Pluto and Charon show the worlds’ highs and lows

    The first global maps of Pluto and its moon Charon are now available, putting a bookend on NASA’s New Horizons mission.

    “From a completionist’s point of view, they are all the good data we have, stitched together into a coherent, complete mosaic,” says planetary scientist Ross Beyer of NASA’s Ames Research Center in Moffett Field, Calif.

    The charts focus on the 42 percent of Pluto...

  • 50 years ago, neutrinos ghosted scientists

    Tracking the neutrino

    The definite detection of nonterrestrial neutrinos, whether from the sun or from beyond the solar system, will yield a far deeper understanding of stellar interiors and, therefore, of how today’s universe came to be. — Science News, July 20, 1968.

    Update

    In May 1968, researchers reported that a particle detector in South Dakota spotted ghostly subatomic...

    Ötzi loaded up on fatty food before he died

    Ötzi didn’t die hungry.

    Around 5,300 years ago, the Iceman dined on wild meat and grains before meeting his end in the Italian Alps. His last meal was high in fat and optimal for a high-altitude trek, researchers report July 12 in Current Biology.

    Since his mummified remains were discovered in 1991, Ötzi’s life has undergone more scrutiny than many reality TV stars. His cause of...

    The ecosystem that controls a galaxy’s future is coming into focus

    There’s more to a galaxy than meets the eye. Galaxies’ bright stars seem to spiral serenely against the dark backdrop of space. But a more careful look reveals a whole lot of mayhem.

    “Galaxies are just like you and me,” Jessica Werk, an astronomer at the University of Washington in Seattle, said in January at a meeting of the American Astronomical Society. “They live their lives in a...

    See this star nursery shine in a stunning new infrared image

    New tech is revealing how young stars have an outsized influence on their environment. In this image from the Very Large Telescope in Chile, hundreds of newborn stars sculpt and illuminate gas and dust in their stellar nursery.

    Released July 11 by the European Southern Observatory, the image shows star cluster RCW 38, which is located about 5,500 light-years from Earth toward the...

    How a particle accelerator helped recover tarnished 19th century images

    With the aid of a particle accelerator, scientists are bringing back ghosts from the past, revealing portraits hidden underneath the tarnished surface of two roughly 150-year-old silver photographic plates.

    Researchers used an accelerator called a synchrotron to produce strong, but nondamaging beams of X-rays to scan the damaged photographs, called daguerreotypes, and map their chemical...

    Why humans, and Big Macs, depend on bees

    Buzz: The Nature and Necessity of BeesThor HansonBasic Books, $27

    When you hear the word bee, the image that pops to mind is probably a honeybee. Maybe a bumblebee. But for conservation biologist Thor Hanson, author of the new book Buzz, the world is abuzz with thousands of kinds of bees, each as beautiful and intriguing as the flowers on which they land.

    Most Americans think funding science pays off

    Forget all the ridicule heaped on treadmill-running shrimp.

    About 80 percent of U.S. adults think that government spending on medical research, engineering and technology, and basic science usually leads to meaningful advances, a new survey from the Pew Research Center shows. The nonprofit, nonpartisan research organization queried 2,537 people from April 23 to May 6.
