    Readers ponder mitochondria, Neandertal diets, deep sea corals and more

    Dad’s contribution

    Scientists have long thought that children inherit mitochondria — tiny energy factories found in cells — from only their mothers. But data from three unrelated families suggest that in rare cases children can also inherit mitochondria from their fathers, Tina Hesman Saey reported in “Dads, not just moms, can pass along mitochondrial DNA” (SN: 1/19/19, p. 8).

    Tidal floods driven by climate change may hurt small businesses

    WASHINGTON — Sea level rise, driven by climate change, is causing increased flooding during high tides along much of the U.S. coastline. Though such floods are usually minor, a new study suggests that car traffic patterns could help reveal how floods harm an area’s business revenues.

    Tidal flooding events “are not one in a hundred years or one in a thousand years. They’re once a week,”...

    An Antarctic expedition will search for what lived under the Larsen C ice shelf

    Maybe the fourth time’s the charm. On February 9, an international team of scientists is embarking on yet another mission to hunt for ocean life that may have once dwelled in the shadow of a giant iceberg (SN Online: 10/13/17).  The scientists, led by researchers at the Alfred Wegener Institute in Bremerhaven, Germany, are headed to the Larsen C ice shelf on the Antarctic Peninsula, where a...

    2018 was the fourth-hottest year on record, and it’s getting even hotter

    Overall, 2018 was the fourth-warmest year on record, and climate change trends suggest that temperatures will only continue to climb, scientists said February 6 during a joint news conference by the National Oceanic and Atmospheric Administration and NASA.

    The agencies’ data show that global atmospheric temperatures in 2018 were on average 0.79 degrees Celsius warmer than the average...

    Collapsing ice cliffs may not contribute to sea level rise

    Sea level rise over the next century won’t get a feared boost from Antarctic ice cliffs crumbling into the ocean like dominoes, a new study suggests.

    The finding, published February 7 in Nature, is based on a new statistical analysis showing that such a rapid collapse of marine ice cliffs in Antarctica was extremely unlikely to have happened in the past, even during some of Earth’s...

    Climate change might not slow ocean circulation as much as thought

    New findings from an international ocean observing network are calling into question the long-standing idea that global warming might slow down a big chunk of the ocean’s “conveyor belt.” The first 21 months of data from sensors moored across much of the North Atlantic are giving new insight into what controls the strength of the Atlantic Meridional Overturning Circulation, a system of...
