    Gene editing of human embryos yields early results

    Scientists have long sought a strategy for curing genetic diseases, but — with just a few notable exceptions — have succeeded only in their dreams. Now, though, researchers in China and Texas have taken a step toward making the fantasies a reality for all inherited diseases.

    Using the gene-editing tool known as CRISPR/Cas9, the researchers have successfully edited disease-causing...

    Spray-on mosquito repellents are more effective than other devices

    Mosquitoes are more than an itchy nuisance. They can carry serious diseases, including Zika, West Nile, yellow fever and chikungunya. Now after testing 11 types of mosquito repellents, researchers say they’ve identified the products most effective at warding off the bloodsuckers.

    Spray-on repellents with DEET or a refined tree extract called oil of lemon eucalyptus are most likely to...

    Palace remains in Mexico point to ancient rise of centralized power

    Remnants of a royal palace in southern Mexico, dating to between around 2,300 and 2,100 years ago, come from what must have been one of the Americas’ earliest large, centralized governments, researchers say.

    Excavations completed in 2014 at El Palenque uncovered a palace with separate areas where a ruler conducted affairs of state and lived with his family, say archaeologists Elsa...

    Most Americans like science — and are willing to pay for it

    Americans don’t hate science. Quite the contrary. In fact, 79 percent of Americans think science has made their lives easier, a 2014 Pew Research Center survey found. More than 60 percent of people also believe that government funding for science is essential to its success.

    But should the United States spend more money on scientific research than it already does? A layperson’s answer to...

    Anatomy analysis suggests new dinosaur family tree

    The standard dinosaur family tree may soon be just a relic.

    After examining more than 400 anatomical traits, scientists have proposed a radical reshuffling of the major dinosaur groups. The rewrite, reported in the March 23 Nature, upsets century-old ideas about dinosaur evolution. It lends support to the accepted idea that the earliest dinosaurs were smallish, two-legged creatures. But...

    Lab tests aren’t the answer for every science question

    In the second half of the 17th century, the chemist and polymath Robert Boyle and philosopher Thomas Hobbes engaged in a divisive debate centered on a temperamental, mechanical contraption known as an air pump. In a series of famous experiments, Boyle used the air pump, which has been called “the cyclotron of its age,” to test basic scientific principles such as the relationship between a gas’...

    How Pluto’s haze could explain its red spots

    Pluto may get its smattering of red spots from the fallout of its hazy blue skies, researchers say.

    Haze particles from the dwarf planet’s atmosphere settle onto all of Pluto’s surfaces. But some regions may become redder and darker than others because parts of the atmosphere collapse, exposing those spots to more surface-darkening radiation from space, researchers report March 22 at the...

    Colorful pinwheel puts a new spin on mouse pregnancy

    View slideshow of other winners

    This rainbow pinwheel of mouse placentas isn’t just an eye-catching, award-winning image. The differences in color also provide researchers with new clues to how a mother’s immune system may affect her or her baby’s health during pregnancy. The work could lead to earlier diagnosis and treatment of preeclampsia, a common pregnancy complication.

    Cancer cells cast a sweet spell on the immune system

    Shrink yourself small enough to swoop over the surface of a human cell, and you might be reminded of Earth’s terrain. Fats, or lipids, stay close to the surface, like grasses and shrubs. Proteins stand above the shrubs, as mighty oaks or palm trees. But before you could distinguish the low-lying lipids from the towering proteins, you’d see something else adorning these molecules — sugars.

    Close pass by sun didn’t radically alter comet 67P’s landscape

    At least one of comet 67P/Churyumov-Gerasimenko’s dusty outbursts was the result of a landslide. But such changes to the surface of the comet haven’t radically altered its appearance, suggesting it has had roughly the same look for decades — or longer.

    Images from the Rosetta spacecraft taken before its demise show what happened to the comet as it passed close to the sun in 2015. Cliffs...
