    Scientists set sail for the elusive island of stability

    On March 6, 1869, Dmitrii Mendeleev’s periodic table was unveiled, and we’ve launched a yearlong celebration of the 150th anniversary of his iconic work. In this issue, we’re looking ahead to imagine the periodic table of the future, as scientists strive to create bizarre new elements. And we also set ourselves a science visualization challenge: charting the half-lives of all the...

    Why kids may be at risk from vinyl floors and fire-resistant couches

    WASHINGTON — Home decor like furniture and flooring may not be notorious polluters like gas-guzzlers, but these indoor consumer products can also be significant sources of potentially dangerous chemicals.

    Kids who live in homes with all vinyl flooring or living room couches that contain flame retardants have much higher concentrations of chemicals called semivolatile organic compounds in...

    Why some Georgia O’Keeffe paintings have ‘art acne’

    WASHINGTON — Like pubescent children, the oil paintings of Georgia O’Keeffe have been breaking out with “acne” as they age, and now scientists know why.

    Tiny blisters, which can cause paint to crack and flake off like dry skin, were first spotted forming on the artist’s paintings years ago. O’Keeffe, a key figure in the development of American modern art, herself had noticed these knobs...

    A new 3-D printed ‘sponge’ sops up excess chemo drugs

    Bringing the filtering abilities of a fuel cell into the blood vessels of living organisms, a new device could cut down on toxic effects of cancer treatment.

    At the heart of this approach — recently tested in pigs — is a tiny, cylindrical “sponge” created by 3-D printing. Wedged inside a vein near a tumor being treated with chemotherapy, the sponge could absorb excess drug before it...

    Your phone could reveal your radiation exposure after a nuclear disaster

    In the event of a nuclear attack or accident, personal electronics could be repurposed as radiation detectors.

    A ceramic insulator found in many devices, such as cell phones and fitness trackers, gives off a glow under high heat that reveals its past nuclear radiation exposure, researchers report in the February Radiation Measurements. That insight may allow experts to gauge someone’s...

    150 years on, the periodic table has more stories than it has elements

    Recognize these rows and columns? You may remember a detail or two about this mighty table’s organization from a long-ago chemistry class. Elements are ordered according to their number of protons, or atomic number. Metals are mostly to the left and nonmetals to the right. The column at the far right holds the noble gases, named for their general unwillingness to interact with other elements...

    How the periodic table went from a sketch to an enduring masterpiece

    Every field of science has its favorite anniversary.

    For physics, it’s Newton’s Principia of 1687, the book that introduced the laws of motion and gravity. Biology celebrates Darwin’s On the Origin of Species (1859) along with his birthday (1809). Astronomy fans commemorate 1543, when Copernicus placed the sun at the center of the solar system.

    And for chemistry, no cause for...

    The periodic table remains essential after 150 years

    It’s another raw day in St. Petersburg, Russia, but the man striding down the University Embankment along the Neva River isn’t pondering how the icy wind off the Gulf of Finland chills his bones or whether Emperor Alexander II’s reforms will increase salaries for professors like him. Instead, Dmitrii Mendeleev is imagining how he could reveal the chemical underpinnings of the universe...

    Green darner dragonflies migrate a bit like monarch butterflies

    The monarch butterfly isn’t the only insect flying up and down North America in a mind-boggling annual migration. Tests show a big, shimmering dragonfly takes at least three generations to make one year’s migratory loop.

    Ecologist Michael Hallworth and his colleagues pieced together the migration of the common green darner, described December 19 in Biology Letters, using data on forms of...

    Why a chemistry teacher started a science board game company

    A physicist, a gamer and two editors walk into a bar. No, this isn’t the setup for some joke. After work one night, a few Science News staffers tried out a new board game, Subatomic. This deck-building game combines chemistry and particle physics for an enjoyable — and educational — time.

    Subatomic is simple to grasp: Players use quark and photon cards to build protons, neutrons and...
