    These weather events turned extreme thanks to human-driven climate change

    NEW ORLEANS — For the first time, scientists have definitively linked human-caused climate change to extreme weather events.

    A handful of extreme events that occurred in 2016 — including a deadly heat wave that swept across Asia — simply could not have happened due to natural climate variability alone, three new studies find. The studies were part of a special issue of the Bulletin of...

    Fracking linked to low birth weight in Pennsylvania babies

    Living near a fracking site appears to be detrimental to infant health, a study eyeing the gas production practice in Pennsylvania suggests.

    Babies of moms living within one kilometer of a hydraulic fracturing, or fracking, site in the state had a 25 percent greater chance of being born underweight than did babies whose moms lived at least three kilometers away, researchers report online...

    Worries grow that climate change will quietly steal nutrients from major food crops

    2017 was a good year for worrying about nutrient losses that might come with a changing climate.

    The idea that surging carbon dioxide levels could stealthily render some major crops less nutritious has long been percolating in plant research circles. “It’s literally a 25-year story, but it has come to a head in the last year or so,” says Lewis Ziska, a plant physiologist with the U....

    What the Pliocene epoch can teach us about future warming on Earth

    Imagine a world where the polar ice sheets are melting, sea level is rising and the atmosphere is stuffed with about 400 parts per million of carbon dioxide. Sound familiar? It should. We’re living it. But the description also matches Earth a little over 3 million years ago, in the middle of the geologic epoch known as the Pliocene.

    To understand how our planet might respond as global...

    Step away from the cookie dough. E. coli outbreaks traced to raw flour

    Eggs, long condemned for making raw cookie dough a forbidden pleasure, can stop taking all the blame. There’s another reason to resist the sweet uncooked temptation: flour.

    The seemingly innocuous pantry staple can harbor strains of E. coli bacteria that make people sick. And, while not a particularly common source of foodborne illness, flour has been implicated in two E. coli outbreaks...

    How Asian nomadic herders built new Bronze Age cultures

    Nomadic herders living on western Asia’s hilly grasslands made a couple of big moves east and west around 5,000 years ago. These were not typical, back-and-forth treks from one seasonal grazing spot to another. These people blazed new trails.

    A technological revolution had transformed travel for ancient herders around that time. Of course they couldn’t make online hotel reservations....

    Whether psychology research is improving depends on whom you ask

    For more than a decade, psychology has been contending with some of its research findings going up in smoke. Widely publicized attempts to replicate major findings have shown that study results that scientists and the public took for granted might be no more than a statistical fluke. We should, for example, be primed for skepticism when studying priming. Power posing may be powerless.

    In many places around the world, obesity in kids is on the rise

    Over the last 40 years, the number of kids and teens with obesity has skyrocketed worldwide. In 1975, an estimated 5 million girls and 6 million boys were obese. By 2016, those numbers had risen to an estimated 50 million girls and 74 million boys, according to a report published online October 10 in the Lancet. While the increase in childhood obesity has slowed or leveled off in many high-...

    Jennifer Dionne harnesses light to illuminate nano landscapes

    Jennifer Dionne, 35Materials scientistStanford University

    To choose her research goals, Jennifer Dionne envisions conversations with hypothetical grandchildren, 50 years down the line. What would she want to tell them she had accomplished? Then, to chart a path to that future, “I work backward to figure out what are the milestones en route,” she says.

    That long-term vision has led...

    The list of diseases linked to air pollution is growing

    To the residents of Donora, Pa., a mill town in a crook of the Monongahela River, the daily haze from nearby zinc and steel plants was the price of keeping their families fed. But on October 27, 1948, the city awoke to an unusually sooty sky, even for Donora. The next day, the high school quarterbacks couldn’t see their teammates well enough to complete a single pass.

    The town was...
