    Why some low-income neighborhoods are better than others

    Chicago’s mayor-elect Lori Lightfoot pledged in her victory speech on April 2 to “make Chicago a place where your zip code doesn’t determine your destiny.” But turning that pledge into reality will require addressing more than poverty, according to a study that followed the lives of thousands of children in the city.

    Kids from low-income neighborhoods that are beset by high rates of...

    The delight of discovering an asteroid that spits

    These are wondrous times for space exploration. Just when you think exploring the cosmos couldn’t possibly get more fun, another discovery delivers a new “oh wow” moment.

    Consider the asteroid Bennu. It’s an unprepossessing space rock that drew scientists’ curiosity because it is among the most pristine objects in our solar system, and it might provide clues to the origins of life....

    What we know and don’t know about how mass trauma affects mental health

    In March, three people connected to mass school shootings died by suicide, raising questions about the lingering effects of such trauma on a person’s mental health.

    Two teenagers who survived the 2018 shooting at Marjory Stoneman Douglas High School in Parkland, Fla., took their own lives within days of each other. The father of a child killed in the 2012 Sandy Hook Elementary School...

    A Nobel Prize winner argues banning CRISPR babies won’t work

    Scientists are vigorously debating how, and if, they can put the human gene-editing genie back in the bottle.

    There is widespread agreement that it’s currently “irresponsible” to make heritable changes in human cells. Gene editors, even the much lauded CRISPR/Cas9 molecular scissors, have not yet been proven safe and effective enough to use to alter genes in the human germline; embryos,...

    The science of CBD lags behind its marketing

    Treatments for pain and other common health problems often fall short, leading to untold misery and frustration. So it’s not hard to understand the lure of a treatment that promises to be benign, natural and good for just about everything that ails you. Enter cannabidiol, or CBD.

    So far, the U.S. Food and Drug Administration has approved only one drug containing the chemical: a...

    The CBD boom is way ahead of the science

    A few months back, a new storefront appeared in my small Oregon town. Its shelves were packed with tinctures, jars of salve, coffee beans, bath bombs — even beard oil. This motley collection shared a single star ingredient: CBD.

    Produced by the cannabis plant, CBD is the straitlaced cousin of marijuana’s more famous component — the THC that delivers a mind-swirling high. CBD, or...

    The learning gap between rich and poor students hasn’t changed in decades

    The average performance of the lowest income students in the United States lags about three to four years behind that of the highest income students — an achievement gap that has remained constant for more than four decades, a new study finds.

    An analysis of standardized tests given to more than 2.7 million middle and high school students over almost 50 years suggests that federal...

    A new T. rex exhibit takes a deep dive into the iconic dinosaur

    Ultrafierce Tyrannosaurus rex is an icon. But the “tyrant lizard king,” which lived between 68 million and 66 million years ago, is just the youngest member of a family of dinosaurs that went back to about 167 million years ago. The earliest tyrannosaurs were quick and small. So how did T. rex become so big and bad?

    That’s one of the questions at the heart of “T. rex: The Ultimate...

    Students worldwide are striking to demand action on climate change

    For the past several months, growing numbers of students around the world have been cutting class — not to play but to protest.

    The topic driving them is the same: Earth’s changing climate, as evidenced by increasing wildfires and droughts, rising seas and more extreme weather. As the students see it, governments have not done enough to cut the emissions of greenhouse gases, such as...

    Geneticists push for a 5-year global ban on gene-edited babies

    Eighteen researchers, including two CRISPR pioneers, are calling for a temporary ban on creating gene-edited babies.

    “We call for a global moratorium on all clinical uses of human germline editing — that is, changing heritable DNA (in sperm, eggs or embryos) to make genetically modified children,” the statement’s cosigners, who come from seven countries, wrote in the March 14 Nature....
